General Surgery - Upper GI Bleeding Flashcards
(105 cards)
1
Q
What is upper GI bleeding?

Q
Why is it possible to have hematochezia?
A
Blood is a cathartic and hematochezia
usually indicates a vigorous rate of
bleeding from the UGI source

Q
Which lab tests should be
performed?

Because of absorption of blood by the GI
tract
15
Q
What is the initial treatment?
A
-
IVFs (16 G or larger peripheral
IVS x 2), Foley catheter (monitor
fluid status) -
NGT suction (determine rate and
amount of blood) - Water lavage (use warm H2O—will
remove clots) -

Intractability
Hemorrhage (massive or relentless)
Obstruction (gastric outlet obstruction)
Perforation
45

Opening of the duodenum through the
pylorus
Oversewing of the bleeding vessel
46

bleeding duodenal ulcers?
Gastroduodenal artery
47
What are the common
surgical options for the
following conditions:
Duodenal perforation?
Graham patch (poor candidates, shock,
prolonged perforation)
Truncal vagotomy and pyloroplasty
incorporating ulcer
Graham patch and highly selective
vagotomy
Truncal vagotomy and antrectomy
(higher mortality rate, but lowest
recurrence rate)
48
Duodenal obstruction resulting from ulcer scarring (gastric outlet obstruction)?
```
Truncal vagotomy, antrectomy, and
duodenal gastroduodenostomy (BI or BII)
Truncal vagotomy and drainage procedure
(gastrojejunostomy)
```
49
Duodenal ulcer intractability?
PGV (highly selective vagotomy)
Vagotomy and pyloroplasty
Vagotomy and antrectomy BI or BII
(especially if there is a coexistent
pyloric/prepyloric ulcer) but
associated with a higher mortality
50
Which ulcer operation has
the highest ulcer recurrence
rate and the lowest dumping
syndrome rate?
PGV (proximal gastric vagotomy)
51
Which ulcer operation has
the lowest ulcer recurrence
rate and the highest
dumping syndrome rate?
Vagotomy and antrectomy
52
Why must you perform a
drainage procedure
(pyloroplasty, antrectomy)
after a truncal vagotomy?
Pylorus will not open after a truncal vagotomy

Which duodenal ulcer operation has the lowest mortality rate?
PGV (1/200 mortality), truncal vagotomy
and pyloroplasty (1–2/200), vagotomy
and antrectomy (1%–2% mortality)
Thus, PGV is the operation of choice
for intractable duodenal ulcers with
the cost of increased risk of ulcer
recurrence
54
What is a “kissing” ulcer?

pH of 7.0 initially
56
Why may a perforated
duodenal ulcer present as
lower quadrant abdominal
pain?
Fluid from stomach/bile drains down paracolic gutters to lower quadrants and causes localized irritation
57

ulcer population)
Rare in patients younger than 40 years
58
How does the incidence in
men compare with that of
women?
Men \> women
59
Which is more common overall: gastric or duodenal ulcers?
Duodenal ulcers are more than twice as
common as gastric ulcers (Think:
Duodenal = Double rate)
60
What is the classic pain
response to food?
Food classically increases gastric ulcer pain
61

67
What is the most common
location?
~70% are on the lesser curvature; 5% are on the greater curvature
68
When and why should biopsy be performed?

69
What is the medical treatment?
Similar to that of duodenal ulcer—PPIs or
H2 blockers, Helicobacter pylori treatment
70
When do patients with gastric ulcers need to have an EGD?

Gastric = increased pain
(Think: Duodenal = Decreased pain)
96
```

poor operative candidates/unstable
patients
Place viable omentum over perforation
and tack into place with sutures
97
Truncal vagotomy
Resection of a 1- to 2-cm segment of
each vagal trunk as it enters the
abdomen on the distal esophagus,
decreasing gastric acid secretion
98
What other procedure must
be performed along with a truncal vagotomy?
“Drainage procedure” (pyloroplasty, antrectomy, or gastrojejunostomy),
because vagal fibers provide relaxation of
the pylorus, and, if you cut them, the
pylorus will not open
99
```
# Define the following terms:
Vagotomy and pyloroplasty
```
Pyloroplasty performed with vagotomy to
compensate for decreased gastric emptying
100
Vagotomy and antrectomy

102
What is the advantage of
proximal gastric vagotomy
(highly selective
vagotomy)?

103
What is a Billroth I (BI)?
Truncal vagotomy, antrectomy, and
gastroduodenostomy (Think: BI ONE
limb off of the stomach remnant)
104
What are the contraindications for a Billroth I?
Gastric cancer or suspicion of gastric cancer
105
