1
00:00:00,000 --> 00:00:02,480
Speaker 1: Today we're gonna be going over gastric disorders, so it's

2
00:00:02,480 --> 00:00:06,120
going to be involving gastritis, peptic ulcer disease, and pyloric stenosis.

3
00:00:06,400 --> 00:00:07,919
And I just want to mention really quick, if you

4
00:00:08,000 --> 00:00:10,800
do like the podcast, it's helping you. Please, please, if

5
00:00:10,800 --> 00:00:14,480
you wouldn't mind giving me a review on Apple Podcasts, Spotify,

6
00:00:14,599 --> 00:00:16,559
just let me know that it's helping you. It kind

7
00:00:16,559 --> 00:00:18,960
of also gets the word out about the podcast and

8
00:00:19,039 --> 00:00:21,559
helps other people discovered as well. I'd really appreciate that.

9
00:00:21,960 --> 00:00:23,800
So with that being said, let's go ahead and start

10
00:00:23,839 --> 00:00:27,920
with aqte gastritis. So qute gastritis is an inflammation resulting

11
00:00:27,920 --> 00:00:30,839
from gastric mucosal injury. It's important to note that there

12
00:00:30,920 --> 00:00:33,799
is something else called gastropathy, which is going to be

13
00:00:33,880 --> 00:00:37,799
a more superficial mucosal injury with no associated inflammation. So

14
00:00:37,840 --> 00:00:39,520
that's another term that you need to know as well.

15
00:00:39,640 --> 00:00:43,920
As far as eteologies, H pylori most common cause by

16
00:00:44,079 --> 00:00:46,679
far H pylori. Remember this is going to be your

17
00:00:46,679 --> 00:00:48,439
most common cause of acte gastritis.

18
00:00:48,719 --> 00:00:49,079
Speaker 2: And H.

19
00:00:49,119 --> 00:00:52,600
Speaker 1: Pylori is a GRAM negative bacteria that's very common. It's

20
00:00:52,600 --> 00:00:55,880
actually found in about half of the world's population, So

21
00:00:56,000 --> 00:00:58,759
not everybody gets symptoms from this though, So just because

22
00:00:58,759 --> 00:01:01,640
it's part of your microbio doesn't mean you're gonna have symptoms,

23
00:01:01,640 --> 00:01:04,879
but the people that do develop symptoms. H Pylori infects

24
00:01:04,879 --> 00:01:08,599
the gastric mucosa. It releases certain enzymes and toxins, and

25
00:01:08,680 --> 00:01:12,000
it injures the epithelial cells of the stomach, which leaves

26
00:01:12,040 --> 00:01:15,319
the stomach more vulnerable to the acid that's present and

27
00:01:15,480 --> 00:01:18,599
causes gastritis. It can cause peptic ulcers as well as

28
00:01:18,640 --> 00:01:21,079
pain and a number of other symptoms. So that's how

29
00:01:21,200 --> 00:01:23,879
H bilori causes that. Again, most common cause. That keep

30
00:01:23,959 --> 00:01:26,519
repeating it because it's important. And then your second most

31
00:01:26,560 --> 00:01:29,519
common cause is going to be from n seds and aspirin.

32
00:01:29,959 --> 00:01:33,280
So the way n seds and aspirin and cause gastritis

33
00:01:33,519 --> 00:01:36,319
one way is that it's just from a superficial irritation

34
00:01:36,480 --> 00:01:39,400
of the epithelium of the gastric mucosa. So that can

35
00:01:39,439 --> 00:01:42,400
happen if you take like eight hundred milligrams vibuprof and

36
00:01:42,439 --> 00:01:44,159
you didn't any food with it, and you just have

37
00:01:44,280 --> 00:01:47,040
this stomach pain for a couple hours. But the more

38
00:01:47,079 --> 00:01:51,359
important factor is that n sets inhibit COX one production,

39
00:01:51,840 --> 00:01:57,920
so COX one production is actually responsible for producing prostag landins.

40
00:01:58,120 --> 00:02:01,040
So if you decrease COX one production, decrease production of

41
00:02:01,079 --> 00:02:04,480
prostic landings. Well, why does that matter. It's because prostac

42
00:02:04,599 --> 00:02:09,240
landins actually inhibit gastric acid secretion, so less prostac landins

43
00:02:09,479 --> 00:02:13,800
means more gastric acid and more irritation like gastritis peptic ulcers.

44
00:02:13,840 --> 00:02:16,960
So that's why n sets are really important as a

45
00:02:17,000 --> 00:02:20,759
factor that can cause gastritis. And that's actually why n

46
00:02:20,879 --> 00:02:24,360
sets like celebres, which is also known as celocoxid, were

47
00:02:24,400 --> 00:02:29,680
created because celebres actually targets COX two rather than COX one,

48
00:02:29,919 --> 00:02:33,039
So this leads to less gastric issues and they have

49
00:02:33,080 --> 00:02:36,240
a number of other cardiovascular problems, but that's besides the point.

50
00:02:36,360 --> 00:02:38,879
But that's why they were created because when you don't

51
00:02:38,879 --> 00:02:41,240
target COX one, you don't affect the prostac landids in

52
00:02:41,240 --> 00:02:43,599
the stomach and you have less gastric problems. So that's

53
00:02:43,639 --> 00:02:46,479
why nc's are a big issue here. Some other less

54
00:02:46,479 --> 00:02:50,560
important causes are going to be alcohol, trauma, acute stress,

55
00:02:51,240 --> 00:02:53,439
radiation and things like that, but the ones you need

56
00:02:53,520 --> 00:02:56,639
to know is going to be h pylori and n sets.

57
00:02:56,680 --> 00:02:59,159
Do not forget those H pyloris You're most common and

58
00:02:59,319 --> 00:03:01,199
says you're second most common costs.

59
00:03:00,919 --> 00:03:01,560
Speaker 2: So remember those.

60
00:03:01,599 --> 00:03:04,879
Speaker 1: As far as the patient presentation, some patients initially may

61
00:03:04,919 --> 00:03:07,680
be asymptomatic, but as it progresses, you're going to have

62
00:03:07,719 --> 00:03:12,439
these non specific symptoms. It's like epigastric discomfort also known

63
00:03:12,479 --> 00:03:15,960
as dyspepsia. They may have some nausea, loss of appetite,

64
00:03:16,080 --> 00:03:18,479
nothing really specific that you need to know that's gonna

65
00:03:18,479 --> 00:03:21,000
stick out in a vignette, but just these non specific

66
00:03:21,039 --> 00:03:26,199
epigastric symptoms. Diagnosing while your test of choice, although it

67
00:03:26,240 --> 00:03:28,080
isn't necessarily going to be the first thing you do,

68
00:03:28,439 --> 00:03:30,400
is going to be an upper endoscopy. This is going

69
00:03:30,439 --> 00:03:34,439
to be your best test. But initially you're going to

70
00:03:34,520 --> 00:03:36,680
do some testing for H pylori because these are things

71
00:03:36,719 --> 00:03:39,120
that are non invasive. You can do a uria breath test,

72
00:03:39,120 --> 00:03:41,280
a fecal antigen test to test for H pylori to

73
00:03:41,319 --> 00:03:42,960
see if you need to treat that. I'll go over

74
00:03:43,000 --> 00:03:45,080
those tests a little bit in pepticals or disease and

75
00:03:45,479 --> 00:03:47,960
what they involve, but those so initially you probably test

76
00:03:48,000 --> 00:03:52,680
for h uria breath test fecal antigen test, and then eventually,

77
00:03:52,719 --> 00:03:55,280
if those tests come back negative, these patients are still

78
00:03:55,280 --> 00:03:58,280
having symptoms, you may move on to an upper endoscopy,

79
00:03:58,280 --> 00:04:01,080
which would be your best test. And this is going

80
00:04:01,120 --> 00:04:03,719
to be patients that are refractory to PPIs, H two

81
00:04:03,719 --> 00:04:05,479
blockers things like that. So some of the ways you

82
00:04:05,479 --> 00:04:10,319
can diagnose test for H pylori, upper endoscopy, and treatment, well,

83
00:04:10,360 --> 00:04:12,800
it all depends on the cause. So if these patients

84
00:04:12,840 --> 00:04:15,159
have H pylori, your test came back positive, you're your

85
00:04:15,280 --> 00:04:17,759
breath test or vecal antigen test came back positive. You're

86
00:04:17,759 --> 00:04:19,839
going to treat H pylori. So how do you treat

87
00:04:19,959 --> 00:04:23,160
H pyloria, whether it's quadruple therapy. Quadruple therapy is going

88
00:04:23,199 --> 00:04:27,160
to be a combination of PPIs, bismuth, metronidazol, and tetracycling.

89
00:04:27,240 --> 00:04:31,160
So H pylori positive treat the H pylori with quadruple therapy.

90
00:04:31,759 --> 00:04:33,759
You want to discontinue n SAID use if that's what's

91
00:04:33,800 --> 00:04:36,800
causing it, and you can also use PPIs and H

92
00:04:36,839 --> 00:04:41,519
two blockers, particularly in patients who require the continued use

93
00:04:41,560 --> 00:04:44,319
of n SET. So whether it's a cardiovascular patient that

94
00:04:44,360 --> 00:04:47,399
requires daily aspirin patient with chronic pain that has to

95
00:04:47,439 --> 00:04:50,360
take their ND sets but they develop gastritis, then you

96
00:04:50,399 --> 00:04:52,600
can use PPIs and H two blockers as well for

97
00:04:52,720 --> 00:04:56,600
the treatment. So treatment depends on the cause H pylori.

98
00:04:56,720 --> 00:04:59,480
Treat the H pylori discontinue n said use if they're

99
00:04:59,560 --> 00:05:02,160
using it, and PPIs and H two blockers are going

100
00:05:02,199 --> 00:05:02,759
to be your main.

101
00:05:02,639 --> 00:05:03,959
Speaker 2: Ways to treat qute gastritis.

102
00:05:04,000 --> 00:05:05,639
Speaker 1: As something else that I'm going to go over, it's

103
00:05:05,759 --> 00:05:07,879
definitely not very high yield, but you need to know

104
00:05:07,920 --> 00:05:10,560
that it exists because it is on the blueprint. It's

105
00:05:10,560 --> 00:05:15,279
something called autoimmune metaplastic atrophic gastritis, so again not high yield,

106
00:05:15,439 --> 00:05:18,000
but be aware that it exists. It's a chronic form

107
00:05:18,040 --> 00:05:22,800
of gastritis. It's an inherited autoimmune disease, so unlike a

108
00:05:22,920 --> 00:05:25,079
cute gastritis, this isn't going to be from N sets

109
00:05:25,160 --> 00:05:28,759
or it's pylori use. It's going to be an autoimmune process.

110
00:05:28,959 --> 00:05:31,800
So the immune system is actually attacking the parietal cells,

111
00:05:31,920 --> 00:05:34,360
an intrinsic factor in the body. This can lead to

112
00:05:34,399 --> 00:05:37,199
B twelve deficiency as well as this gastritis that these

113
00:05:37,199 --> 00:05:40,480
patients have. These patients are also at a high risk

114
00:05:40,920 --> 00:05:42,360
of gastric carcinoma.

115
00:05:42,839 --> 00:05:44,160
Speaker 2: And one other important thing.

116
00:05:44,040 --> 00:05:46,800
Speaker 1: That you need to know is that while acute gastritis

117
00:05:47,040 --> 00:05:50,680
most commonly affects the antrum of the stomach, chronic or

118
00:05:50,720 --> 00:05:54,480
autoimmune gastritis spares the antrum and most commonly affects the

119
00:05:54,519 --> 00:05:57,759
fundus or the body. So for real life maybe not

120
00:05:57,839 --> 00:06:01,600
so important, but for a vin yet they may mention that.

121
00:06:01,680 --> 00:06:05,920
So remember a QT gastritis affects the antrum, chronic autoimmune

122
00:06:06,000 --> 00:06:07,759
is going to most commonly affect the fundus in the

123
00:06:07,800 --> 00:06:10,160
body and spares the andantrum. That's really all you need

124
00:06:10,199 --> 00:06:12,120
to know for that. Don't go crazy again, not very

125
00:06:12,199 --> 00:06:12,680
high yield.

126
00:06:13,000 --> 00:06:13,959
Speaker 2: Now moving on.

127
00:06:13,920 --> 00:06:16,439
Speaker 1: To something that is high yield is peptic ulcer disease.

128
00:06:16,439 --> 00:06:17,560
So there's a lot of stuff you need to know

129
00:06:17,600 --> 00:06:19,040
on this. Let's go over that. There's going to be

130
00:06:19,079 --> 00:06:21,800
some overlap two with gastritis as well. So peptic ulcer

131
00:06:21,839 --> 00:06:26,480
disease encompasses both duodenal ulcers and gastric ulcers. So some

132
00:06:26,560 --> 00:06:28,399
things that two have in common, some things that help

133
00:06:28,439 --> 00:06:30,959
differentiate them. So we'll go over the different things. So

134
00:06:31,040 --> 00:06:34,279
let's start with duoden ulcers so duoden ulcers are going

135
00:06:34,319 --> 00:06:37,240
to be an area of erosion obviously in the duodenum.

136
00:06:37,439 --> 00:06:39,600
It's going to be your most common type, so much

137
00:06:39,639 --> 00:06:42,920
more common, about four times more common than gastric ulcers,

138
00:06:43,160 --> 00:06:46,399
and usually it's benign. Gastric Ulcers are going to be

139
00:06:46,600 --> 00:06:49,199
an area of erosion in the stomach, and these are

140
00:06:49,279 --> 00:06:53,680
less prevalent than duodenal ulcers and more commonly associated with

141
00:06:53,800 --> 00:06:58,279
gastric edinal carcinoma. So remember that duodenal ulcers usually benign.

142
00:06:58,399 --> 00:07:02,680
Gastric ulcers are more commonly associated with gastric adino carcinoma,

143
00:07:02,800 --> 00:07:05,600
and duoden ulcers are your more common type as far

144
00:07:05,639 --> 00:07:09,079
as eteologies, a lot of overlap here with gastritis. Again

145
00:07:09,360 --> 00:07:12,480
h pylori most common cause overall, nothing new that you

146
00:07:12,480 --> 00:07:15,360
need to know there, Second most common cause, N SAIDs

147
00:07:15,360 --> 00:07:18,160
an aspirin really easy. You already know this for gastritis,

148
00:07:18,360 --> 00:07:22,000
So again hpylori most common. N says an aspirin second

149
00:07:22,079 --> 00:07:24,959
most common. And then another odd bowl that you need

150
00:07:25,040 --> 00:07:27,800
to know of that's not very common about you know,

151
00:07:27,839 --> 00:07:30,360
like less than one percent of patients. It's something called

152
00:07:30,439 --> 00:07:35,160
Zollinger Ellison syndrome and This is a disease that produces

153
00:07:35,279 --> 00:07:40,040
high levels of gastrin from a neuroendocrine tumor, and gastrin

154
00:07:40,120 --> 00:07:42,079
leads to high levels of acid in the stomach, which

155
00:07:42,079 --> 00:07:44,639
can lead to ulcers and gastritis as well as another

156
00:07:44,800 --> 00:07:47,600
a few other things. So again not a very common cause,

157
00:07:47,600 --> 00:07:49,240
but something that you do need to know because it

158
00:07:49,240 --> 00:07:52,439
may come up in the boards, and just a small

159
00:07:52,519 --> 00:07:54,560
factor that you need to know as well. So hpylori

160
00:07:54,639 --> 00:07:56,279
is your most common cause overall, but it's going to

161
00:07:56,319 --> 00:07:59,879
be more associated with duodeno ulcers, where n sets an asper,

162
00:08:00,079 --> 00:08:02,240
your second most common cause overall is going to be

163
00:08:02,319 --> 00:08:05,360
more commonly associated with gaster cultures, So just know that,

164
00:08:05,439 --> 00:08:09,360
but again same overlap with gastritis. Hpylori most common, and

165
00:08:09,439 --> 00:08:11,560
sayd as an aspirin second most common, and then just

166
00:08:11,680 --> 00:08:15,000
know about zolinger ellison just as that oddball that may

167
00:08:15,000 --> 00:08:17,399
come up, as well as some of the other factors

168
00:08:17,439 --> 00:08:19,240
you know that can lead to pepic ulcers as well.

169
00:08:19,759 --> 00:08:23,240
Increased alcohol use, smoking also more common and elderly. Those

170
00:08:23,279 --> 00:08:25,120
are the less less important things that you need to know.

171
00:08:25,319 --> 00:08:27,920
But of course hpilor and SAIDs know those. Don't forget

172
00:08:27,959 --> 00:08:31,240
that as far as the history and exam, these patients

173
00:08:31,279 --> 00:08:36,399
are going to have some again non specific epigastric pain, burning, nausea,

174
00:08:36,440 --> 00:08:37,799
they may have early satiety.

175
00:08:38,159 --> 00:08:39,480
Speaker 2: Those things aren't that important.

176
00:08:39,519 --> 00:08:42,000
Speaker 1: It's not going to help you differentiate on of it and yet,

177
00:08:42,200 --> 00:08:44,120
But what you do need to know with this on

178
00:08:44,159 --> 00:08:47,679
the history and exam is the different presentation. Do oddinal

179
00:08:47,799 --> 00:08:51,360
ulcers are going to get better with food? Gastric ulcers

180
00:08:51,399 --> 00:08:54,200
are going to get worse with food. So why does

181
00:08:54,240 --> 00:08:58,000
that happen? Well, gastric cultures. When you eat, acids obviously

182
00:08:58,039 --> 00:09:00,240
released to help break down the food, and so the

183
00:09:00,320 --> 00:09:02,799
ulcers in the stomach you have pain right away. So

184
00:09:02,799 --> 00:09:05,799
as soon as you eat, immediately these patients start having pain,

185
00:09:06,159 --> 00:09:08,960
whereas duadinal ulcers obviously a little bit further down the

186
00:09:08,960 --> 00:09:12,080
GI tract. As you're eating, the food's kind of shut down,

187
00:09:12,159 --> 00:09:14,840
it's clamped off, it's churning up in there trying to

188
00:09:14,840 --> 00:09:17,440
break down the food. So all the acids in the stomach,

189
00:09:17,840 --> 00:09:19,840
but it's not until about two to five hours later

190
00:09:19,879 --> 00:09:22,600
that the food starts to be released from the stomach

191
00:09:22,840 --> 00:09:26,399
enters the duodom. Now these patients start to have pain.

192
00:09:26,799 --> 00:09:29,159
So while these patients are eating and they have a

193
00:09:29,240 --> 00:09:31,399
duodin ulcer. They have some relief for about two to

194
00:09:31,480 --> 00:09:34,440
five hours while the acids still sitting in the stomach.

195
00:09:34,480 --> 00:09:36,120
Speaker 2: Once it starts to come out, then they have pain.

196
00:09:36,480 --> 00:09:39,799
Speaker 1: So duodenal ulcers they're gonna have, They're gonna have relief

197
00:09:40,200 --> 00:09:43,759
with food. They're gonna see their symptoms improved. Duadinals are

198
00:09:43,759 --> 00:09:46,000
going to be better with food. Gastric is gonna be

199
00:09:46,000 --> 00:09:49,320
worse with food. The way I remember that duodenal ulcers.

200
00:09:49,480 --> 00:09:52,360
Du I remember, dude, give me food?

201
00:09:52,639 --> 00:09:53,320
Speaker 2: Do you do?

202
00:09:54,039 --> 00:09:56,639
Speaker 1: Just like in dude and duodenal? Dude give me food?

203
00:09:57,039 --> 00:09:59,919
So better with food, duodonal ulcers and gastric.

204
00:09:59,559 --> 00:10:00,600
Speaker 2: Is worse with food.

205
00:10:00,879 --> 00:10:04,559
Speaker 1: And that's why patients with gastric ulcers that the pain

206
00:10:04,600 --> 00:10:06,320
gets worse with eating. A lot of times you'll see

207
00:10:06,320 --> 00:10:09,519
weight loss in these individuals compared to duaden ulcers. You

208
00:10:09,559 --> 00:10:13,200
may see weight gain because their symptoms get better with food,

209
00:10:13,279 --> 00:10:15,200
so they tend to eat more, So it makes sense.

210
00:10:15,480 --> 00:10:16,360
Speaker 2: One other thing to be.

211
00:10:16,360 --> 00:10:19,799
Speaker 1: Mindful of is that peptic ulcers can bleed and they

212
00:10:19,799 --> 00:10:22,919
can also perforate, So you need to know that peptic

213
00:10:23,000 --> 00:10:26,759
ulcers are actually peptic ulcer disease is the most common

214
00:10:27,159 --> 00:10:30,399
cause of an upper GI bleed. Peptic Ulcer disease most

215
00:10:30,440 --> 00:10:32,840
common cause of an upper GI bleed. And in the

216
00:10:32,879 --> 00:10:35,759
case that they do perforate, these patients are going to

217
00:10:35,840 --> 00:10:39,159
go from this kind of vague epigastric pain pepsia blah

218
00:10:39,200 --> 00:10:43,200
blah blah, to this sudden onset of this sharp, acute

219
00:10:43,240 --> 00:10:46,399
abdominal pain. They may have signs of peritonitis like rebound

220
00:10:46,440 --> 00:10:50,320
tenderness guarding. So know that these peptic ulcers can perforate,

221
00:10:50,399 --> 00:10:52,559
they can bleed, and the presentation is going to be

222
00:10:52,639 --> 00:10:55,080
much different. It's obviously a much more serious situation as

223
00:10:55,120 --> 00:10:59,159
far as diagnosing. Ultimately, your most sensitive and specific test

224
00:10:59,279 --> 00:11:01,799
is going to be in an endoscopy, But there's a

225
00:11:01,840 --> 00:11:03,279
few things you want to do before you get to

226
00:11:03,320 --> 00:11:07,000
an endoscopy. But remember, if an endoscopy is on the

227
00:11:08,000 --> 00:11:10,440
answer listen it says what is your best test endoscopy,

228
00:11:10,480 --> 00:11:12,720
it's always going to be the endoscopy. But in real life,

229
00:11:12,759 --> 00:11:14,039
there's a few things that you're going to do first

230
00:11:14,080 --> 00:11:16,279
and a few other tests. So if it says what's

231
00:11:16,320 --> 00:11:18,480
your initial test, you may go with some other things.

232
00:11:18,480 --> 00:11:20,759
So let's go over that Initially you're probably going to

233
00:11:20,840 --> 00:11:22,559
test for H. Pylori, So you can do that a

234
00:11:22,600 --> 00:11:24,679
couple of different ways. You can do a urrea breath

235
00:11:24,720 --> 00:11:28,200
test or an H. Pylori stool antigen H pylori testing.

236
00:11:28,200 --> 00:11:30,120
When you do a uria breath test, what you need

237
00:11:30,120 --> 00:11:33,639
to know about this is is that H. Pylori produces

238
00:11:33,679 --> 00:11:38,480
an enzyme called urease, which breaks down urrea into ammonia

239
00:11:38,519 --> 00:11:41,360
and carbon dioxide. So the way this test works is

240
00:11:41,399 --> 00:11:43,679
that during the test, the patient is given a pill

241
00:11:43,720 --> 00:11:46,919
containing urea and then they blow into this bag. They

242
00:11:46,960 --> 00:11:48,799
blow into the bag, they close off the bag, it's

243
00:11:48,799 --> 00:11:50,240
sent to a lab, and then they test for the

244
00:11:50,279 --> 00:11:53,240
amount of exhaled carbon dioxide. And remember again they were

245
00:11:53,240 --> 00:11:56,960
given urea, and as I said before, H pylori turns

246
00:11:57,120 --> 00:11:59,480
urea into carbon dioxide and ammonia. So if there's an

247
00:11:59,480 --> 00:12:02,000
increase in all this carbon dioxide that's in this bag,

248
00:12:02,159 --> 00:12:04,240
then obviously this is gonna be a positive test for H.

249
00:12:04,240 --> 00:12:04,639
Speaker 2: Pylori.

250
00:12:04,720 --> 00:12:07,960
Speaker 1: So that's how a urrea breath test works. H Pylori

251
00:12:08,000 --> 00:12:10,799
stool intogen is straightforward. It's literally just checking for a

252
00:12:10,840 --> 00:12:11,840
stool antigen of H.

253
00:12:11,840 --> 00:12:12,240
Speaker 2: Pylori.

254
00:12:12,399 --> 00:12:14,120
Speaker 1: So that's another test that you can do as well.

255
00:12:14,360 --> 00:12:16,840
And then ultimately, like I said before, the gold standard

256
00:12:16,879 --> 00:12:19,840
test is going to be your endoscopy. That's going to

257
00:12:19,879 --> 00:12:21,759
be to diagnose. You can visualize the ulcer and you

258
00:12:21,799 --> 00:12:24,919
can take biopsies if needed, and then treatment depends on

259
00:12:24,960 --> 00:12:28,000
the cause. So let's start with H pylori. If this

260
00:12:28,080 --> 00:12:31,840
patient is H pylori positive, again, just like in guesstritis,

261
00:12:31,919 --> 00:12:34,440
you're going to do quadruple therapy. The way I remember

262
00:12:34,519 --> 00:12:38,159
quadruple therapy for an hpylori positive patient is I remember

263
00:12:38,480 --> 00:12:41,600
these patients have belly pain. They want you to treat

264
00:12:41,600 --> 00:12:43,399
their belly pain so they can get better. So they

265
00:12:43,440 --> 00:12:47,840
say to you, treat my belly, please, treat my belly please.

266
00:12:48,279 --> 00:12:55,000
TMBP that stands for tetracycling, metronideisol, bismyth subseliciy, and PPIs

267
00:12:55,120 --> 00:12:59,480
treat my belly please. Tetracycling, metronide, is al, bismuth, subselicily,

268
00:12:59,639 --> 00:13:03,159
and P. Those are for your H. Pylori positive patients. Now,

269
00:13:03,159 --> 00:13:05,840
if these patients are hpylori negative, how do you treat

270
00:13:05,840 --> 00:13:08,919
their peptic ulcer disease? Well, first, treat the underlying cause.

271
00:13:09,399 --> 00:13:13,240
If they're taking nsids, they're smokers, they drink a bunch

272
00:13:13,240 --> 00:13:16,039
of alcohol. You're going to discontinue all those things obviously,

273
00:13:16,519 --> 00:13:19,039
and then you're going to give them PPIs as well.

274
00:13:19,879 --> 00:13:24,000
You can also use H two blockers, but realistically, anytime

275
00:13:24,039 --> 00:13:25,919
you have an option of a PPI or an H

276
00:13:26,000 --> 00:13:30,519
two blocker, unless there's some contraindication of PPIs, always use PPIs.

277
00:13:30,840 --> 00:13:34,639
Why is that PPIs are much more effective, and that's because,

278
00:13:34,799 --> 00:13:37,000
I mean, just really quickly break down the way these

279
00:13:37,039 --> 00:13:38,639
work and just to give you a little bit about

280
00:13:38,679 --> 00:13:41,440
the may of the mets. So you have a parietal

281
00:13:41,519 --> 00:13:44,799
cell in the stomach. The parietal cell has a proton pump.

282
00:13:44,919 --> 00:13:47,759
That's what shoots out all the hydrochloric acid into the stomach.

283
00:13:48,039 --> 00:13:50,399
That's where all of your acid in the stomach comes from.

284
00:13:50,759 --> 00:13:54,440
So how is your prietal cell activated. Well, acetylcholine, histamine,

285
00:13:54,440 --> 00:13:58,279
and gastrin all activate the prietal cell to pump out

286
00:13:58,279 --> 00:14:02,320
this acid. An H CH two blocker obviously blocks H

287
00:14:02,440 --> 00:14:05,639
two and that's histamine, So that's a histamine blocker, So

288
00:14:05,720 --> 00:14:09,360
it blocks just histamine, but you still have acetocholine and

289
00:14:09,399 --> 00:14:12,480
gastrine that can activate the parietal cell. So while it

290
00:14:12,639 --> 00:14:15,879
helps because you stop the histamine from activating the paryal cell.

291
00:14:16,039 --> 00:14:18,840
Stylcholine and gastrine are still working there to pump out acid,

292
00:14:19,039 --> 00:14:22,159
so there's still some acid production, Whereas a proton pump

293
00:14:22,159 --> 00:14:26,200
inhibitor actually completely shuts off the proton pump, so it

294
00:14:26,200 --> 00:14:28,639
doesn't matter how much is stylcholine, how much histamine, how

295
00:14:28,679 --> 00:14:32,120
much gastrine is activating that parietal cell. The pump is

296
00:14:32,159 --> 00:14:35,159
shut off, so no acids coming out. So PPIs are

297
00:14:35,240 --> 00:14:37,440
much more effective. So remember, if you have an option

298
00:14:37,519 --> 00:14:40,159
of a PPI or hto blocker, use the PPI. So

299
00:14:40,200 --> 00:14:44,080
again H pylor negative, treat the underlying cause, give them PPIs.

300
00:14:44,360 --> 00:14:47,279
That's the treatment. If they're H pylori positive, treat the

301
00:14:47,399 --> 00:14:50,639
H pylori very easy treatment. And then there's one other

302
00:14:50,679 --> 00:14:54,480
treatment option that you should probably know. For refractory patients.

303
00:14:54,519 --> 00:14:58,679
The PPIs aren't working, you discontinued all the ensis, et cetera,

304
00:14:58,960 --> 00:15:01,320
and they're still having SIN, you can do something called

305
00:15:01,320 --> 00:15:04,519
the parietal cell veagotomy, which is where they sever the

306
00:15:04,600 --> 00:15:09,000
vagual nerve, which essentially shuts down the portion of the

307
00:15:09,039 --> 00:15:12,440
stomach where the parietal cells are located. And this obviously

308
00:15:12,519 --> 00:15:15,759
leads to decreased acid by about seventy five percent, So

309
00:15:15,799 --> 00:15:18,639
pretty effective procedure, but it's invasive. Obviously, there's a lot

310
00:15:18,679 --> 00:15:20,320
of things you want to try before you get to

311
00:15:20,360 --> 00:15:22,240
a parietal cell vegotamin. This is just going to be

312
00:15:22,240 --> 00:15:25,080
for your refractory patients. So those are the treatments. Let's

313
00:15:25,120 --> 00:15:26,879
move on to the home stretch here. The last thing

314
00:15:26,879 --> 00:15:28,039
we're going to go over, and that's going to be

315
00:15:28,039 --> 00:15:30,720
pyloric stenosis. So this is going to be a condition

316
00:15:30,960 --> 00:15:33,879
commonly in newborns. About three to six weeks is going

317
00:15:33,919 --> 00:15:36,279
to be your most common age range, and it's a

318
00:15:36,320 --> 00:15:42,000
thickening hypertrophy, a thickening or hypertrophy of the pyloris, which

319
00:15:42,039 --> 00:15:45,080
is the sphincter, the muscular valve between the stomach and

320
00:15:45,120 --> 00:15:49,399
the duodenum, so it prevents gastric emptying. Risk factors are

321
00:15:49,440 --> 00:15:52,399
going to be males four times more common in male,

322
00:15:52,480 --> 00:15:55,200
so definitely know that males are going to be much

323
00:15:55,200 --> 00:15:58,279
more common. Look at your vignette. If it's a female,

324
00:15:58,720 --> 00:16:00,519
you know for a vignette probably and that's so common

325
00:16:00,519 --> 00:16:03,000
that it's going to be pylar scinosis. Three to six

326
00:16:03,039 --> 00:16:05,360
weeks is going to be your most common age of presentation.

327
00:16:05,720 --> 00:16:08,440
Sometimes they'll say three to twelve, but generally three to

328
00:16:08,480 --> 00:16:11,519
six is the most common. And then first born patients

329
00:16:11,519 --> 00:16:13,240
are also going to be at a higher risk. And

330
00:16:13,279 --> 00:16:15,919
then the last thing too, not as you know, not

331
00:16:15,960 --> 00:16:17,639
as big of a risk as the other ones, but

332
00:16:17,799 --> 00:16:22,279
macrolide antibiotics, in particular erythromycin within the first two weeks

333
00:16:22,720 --> 00:16:26,200
of birth can also lead to pyloric stenosis. And this

334
00:16:26,360 --> 00:16:29,600
is the way it's explained, is most likely due to

335
00:16:29,639 --> 00:16:33,840
the increased gastric motility with macrolight antibiotics. Erythromycin, even a

336
00:16:33,919 --> 00:16:37,240
zythromycin can cause this. So the increased gastric motility in

337
00:16:37,279 --> 00:16:40,279
these drugs can lead to hypertrophy from the pyloris basically

338
00:16:40,320 --> 00:16:43,200
just being overworked. And it's the same reason that we

339
00:16:43,320 --> 00:16:47,360
use erythromycin and gastroparesis because it increases the gimotility. So

340
00:16:47,399 --> 00:16:49,480
if you have a patient under two weeks they give

341
00:16:49,519 --> 00:16:52,200
them a erythromycin, this may lead to pyloric stenosis. So

342
00:16:52,279 --> 00:16:55,639
risks again males first born three to six weeks of

343
00:16:55,679 --> 00:16:59,240
life and macrolide antibiotics in particular erythromycin. All right, So

344
00:16:59,519 --> 00:17:02,559
as far as the history and the exam. They may

345
00:17:02,600 --> 00:17:06,599
have some non specific symptoms weight loss, dehydration doesn't matter.

346
00:17:06,680 --> 00:17:08,319
You don't care about that stuff because it's not going

347
00:17:08,359 --> 00:17:11,079
to help you differentiate it in Yet, what you need

348
00:17:11,119 --> 00:17:14,079
to know for pylor ex stenosis, there's two really big

349
00:17:14,119 --> 00:17:19,359
things you cannot forget. So pilar stenosis non bilious projectile

350
00:17:19,440 --> 00:17:22,160
vomiting after feeding. That is going to be your vignette

351
00:17:22,240 --> 00:17:24,400
right there. You can just go ahead and circle pilar stenosis.

352
00:17:24,480 --> 00:17:26,440
That's gonna be your answer. So you see non bilious

353
00:17:26,440 --> 00:17:29,839
projectile vomiting after feeding pilar stenosis. So why is it

354
00:17:29,960 --> 00:17:33,599
non bilious? Well, remember this is an obstruction at the stomach.

355
00:17:33,640 --> 00:17:36,519
It's at the pylorus, so we're not into the area

356
00:17:36,519 --> 00:17:38,759
where the bile is coming from the common bioduct. It's

357
00:17:38,799 --> 00:17:41,880
not evolves. It's an unomal rotation of the small bowel,

358
00:17:41,920 --> 00:17:43,559
so we're not in the area where the bile is

359
00:17:43,599 --> 00:17:46,839
being excreted. So it's gonna be non bilious. It's in

360
00:17:46,880 --> 00:17:50,200
the stomach, So non bilious projectile vomiting after feeding that

361
00:17:50,359 --> 00:17:53,359
is going to be pathonomoonic, almost as pathonomonic as The

362
00:17:53,400 --> 00:17:55,119
second thing you need to know for the exam and

363
00:17:55,160 --> 00:17:58,000
that's going to be an olive shaped mass. So on

364
00:17:58,079 --> 00:18:01,720
physical exam, we talked about the the pyloris being hypertropheed.

365
00:18:01,759 --> 00:18:04,960
It's enlarged, and on physical exam, normally you're not gonna

366
00:18:04,960 --> 00:18:07,119
be able to feel the pylorus. But these patients, because

367
00:18:07,119 --> 00:18:10,599
it's hypertrop feed, you're actually going to feel this olive

368
00:18:10,640 --> 00:18:14,440
shaped mass in the epigastric area and it's going to

369
00:18:14,480 --> 00:18:16,759
feel like a small round mass and it's described as

370
00:18:16,799 --> 00:18:20,559
an olive shaped mass. If you see this on a vignette,

371
00:18:20,680 --> 00:18:22,559
you see this or you feel this in real life,

372
00:18:22,599 --> 00:18:25,640
this is really pathdomonic for the disease. And actually, years ago,

373
00:18:25,720 --> 00:18:29,680
before ultrasound was around, this would be the only way

374
00:18:29,680 --> 00:18:31,720
you would diagnose it. If you felt this olive shaped mass,

375
00:18:31,720 --> 00:18:34,000
they would go right to surgery, you know, after you

376
00:18:34,119 --> 00:18:36,720
treated them with fluids and things like that. So physical

377
00:18:36,759 --> 00:18:41,119
exam no non bilious projectile vomiting and no olive shaped mass.

378
00:18:41,119 --> 00:18:42,440
So those are the two things you need to know

379
00:18:42,559 --> 00:18:45,319
as far as diagnosing. Ultrasound is going to be your

380
00:18:45,359 --> 00:18:48,240
test of choice. It's ninety seven to ninety nine percent

381
00:18:48,400 --> 00:18:50,079
sensitive no radiation.

382
00:18:50,160 --> 00:18:50,920
Speaker 2: These are newborns.

383
00:18:50,920 --> 00:18:52,440
Speaker 1: You really don't want to radiate them if you don't

384
00:18:52,480 --> 00:18:54,400
have to. And then on the ultrasound, you're going to

385
00:18:54,440 --> 00:18:58,119
see some pyloric muscle thickness over four millimeters and the

386
00:18:58,160 --> 00:19:00,960
pyloric canal length will be over seven eighteen millimeters. Don't

387
00:19:00,960 --> 00:19:03,079
worry about those numbers, but I just want to throw

388
00:19:03,119 --> 00:19:05,200
that out there so you know that's how you actually

389
00:19:05,400 --> 00:19:06,559
have a positive ultrasound.

390
00:19:06,559 --> 00:19:08,200
Speaker 2: But ultra sound is gonna be your test of choice.

391
00:19:08,240 --> 00:19:09,839
Speaker 1: The only reason I'm even going to mention an upper

392
00:19:09,839 --> 00:19:11,559
GI series not so much that you're going to use

393
00:19:11,559 --> 00:19:12,920
it in real life. It's really only going to be

394
00:19:12,920 --> 00:19:17,079
if ultrasounds inconclusive, the physical exam is inconclusive. But you

395
00:19:17,160 --> 00:19:18,960
need to know for the exam because on an upper

396
00:19:18,960 --> 00:19:21,000
GI series, there's a couple of key terms.

397
00:19:21,200 --> 00:19:22,759
Speaker 2: There's one called a string sign.

398
00:19:22,799 --> 00:19:26,200
Speaker 1: It's not specific only to pyloxynosis, but if you do

399
00:19:26,279 --> 00:19:28,559
see it in this vignette, this is going to be

400
00:19:28,599 --> 00:19:32,000
a narrowed area of barium flow. It's literally going to

401
00:19:32,079 --> 00:19:35,160
look like a string of barium because that hypertro feed

402
00:19:35,160 --> 00:19:37,960
area only allowing a small amount of barium through. So

403
00:19:37,960 --> 00:19:40,319
that's a string sign and upper GI. And there's another

404
00:19:40,400 --> 00:19:43,559
one called a railroad track sign, and this is due

405
00:19:43,640 --> 00:19:49,240
to the pyloric mucosa compressing and pushing causing this double

406
00:19:49,319 --> 00:19:52,359
canal where you're going to see two small tracks of

407
00:19:52,400 --> 00:19:54,599
barium flowing through. It kind of looks like a railroad

408
00:19:54,759 --> 00:19:57,000
and that's a railroad sign on upper GI. So again

409
00:19:57,039 --> 00:19:59,160
in real life, probably not going to do an UPPERGI,

410
00:19:59,279 --> 00:20:01,240
but you do need to know for the exams because

411
00:20:01,279 --> 00:20:02,960
they like to throw out these key terms of string

412
00:20:03,039 --> 00:20:05,920
sign and railroad track sign on what you'll see on UPPERGI.

413
00:20:06,079 --> 00:20:08,240
And then as far as labs, they're vomiting up all

414
00:20:08,240 --> 00:20:13,359
the stomach acids, so you may have this hypochloromic metabolic acidosis.

415
00:20:13,519 --> 00:20:17,079
They may also have hypokalmia, and this is just because

416
00:20:17,279 --> 00:20:20,720
the kidney's compensating and flushing out all of the renal

417
00:20:20,759 --> 00:20:26,200
potassium excretion. So hypochloromic metabolic acidosis may be seen. And

418
00:20:26,240 --> 00:20:29,400
then they also may have hypokalemia on labs. But your

419
00:20:29,480 --> 00:20:31,519
key for diagnosis is going to be your ultrasound. But

420
00:20:31,559 --> 00:20:34,000
know these things as well. So as far as treatment,

421
00:20:34,599 --> 00:20:38,039
initially these patients can be kind of sick. They're volume depleted,

422
00:20:38,359 --> 00:20:40,519
so before you get to any intervention, you need to

423
00:20:40,559 --> 00:20:44,200
start with some fluids. You want to do electrolyte replacement.

424
00:20:44,240 --> 00:20:46,680
Remember again I said they may be HYPOKLEMICX you want

425
00:20:46,680 --> 00:20:49,759
to replace the potassium, may give them some dextros IV

426
00:20:49,839 --> 00:20:52,720
fluids and things like that. Once they're euvulymic, then you

427
00:20:52,759 --> 00:20:54,799
get to the actual procedure that needs to be done

428
00:20:54,799 --> 00:20:57,599
in these patients. And this is called the pyloral miotomy

429
00:20:57,839 --> 00:20:59,440
is the name of the procedure that you want to

430
00:20:59,480 --> 00:21:03,640
do once they're stable their euvolemic and this is normally

431
00:21:03,640 --> 00:21:08,400
done laparoscopically. The surgeon makes this longitudinal incision into the

432
00:21:08,400 --> 00:21:12,759
pylorus and once they make this longitudinal incision, that hypertrophied

433
00:21:12,880 --> 00:21:16,319
muscle kind of pops out through this incision that they made.

434
00:21:16,480 --> 00:21:19,920
And once it pops up through this area of the incision,

435
00:21:20,480 --> 00:21:23,960
now beneath the area of the incision, there's this canal

436
00:21:24,000 --> 00:21:26,319
that opened up this new space because all the muscle

437
00:21:26,400 --> 00:21:29,000
kind of tunneled up through this incision, and they actually

438
00:21:29,160 --> 00:21:32,480
have this area where the stomach contents can flow through

439
00:21:32,480 --> 00:21:36,839
this area, so that again it's called a pyloromiotomy. Pyloromotomy

440
00:21:37,000 --> 00:21:39,440
is going to be the treatment of choice once these

441
00:21:39,440 --> 00:21:43,000
patients are stable and euvolemic, so that's what you need

442
00:21:43,039 --> 00:21:45,640
to know. Those are the main things. I feel like

443
00:21:45,640 --> 00:21:48,200
I kind of touched on all the high yield stuff.

444
00:21:48,400 --> 00:21:51,559
I hope that was helpful. And as always, good luck

445
00:21:51,640 --> 00:21:54,480
on your pants, your panry, your ear, and good luck

446
00:21:54,519 --> 00:22:00,039
in PA school and
