Slide 10 of 21
Indications for Surgery in Gastrointestinal Hemorrhage
Hemodynamic instability despite vigorous resuscitation (>6 U transfusion)
Failure of endoscopic techniques to arrest hemorrhage
Recurrent hemorrhage after initial stabilization (with up to two attempts at obtaining endoscopic hemostasis)
Shock associated with recurrent hemorrhage
Continued slow bleeding with a transfusion requirement >3 U/day

2) With regard to hemorrhage complicating duodenal ulcer,
which is true ?

2) With regard to hemorrhage complicating duodenal ulcer,
which is true ? (A.)
A. It is a more common common complication of DU than is perforation – melena/hematemesis; eroded GDUB. Endoscopic treatment before operation decreases mortalityC. Endoscopic treatment decreases the need for operation D. Operative management is indicated only if endoscopic treatment fails – active arterial spurting/visible vessel predict recurrent bleedE. Operative management should not include an acid-reducing procedure – suture ligate GDA vessels. Truncal vagotomy + pyloroplasty; parietal cell vagotomy + antrectomy

3) Concerning “stress” bleeding from acute erosive gastritis, which of the
following statements is true ?A. Prophylactic treatments with H2 blockers and anatacids are equally effectiveB.The incidence of such bleeding has been decreasingC. The site of hemorrhage is most often in the antrumD. There is minimal recurrent bleeding after treatment by oversewing of bleeding sites, vagotomy, and pyloroplastyE. Effective surgical treatment necessitates total gastrectomy

3) Concerning “stress” bleeding from acute erosive gastritis, which of the following statements is true ? (B.)
A. Prophylactic treatments with H2 blockers and anatacids are equally effective antacids best titrated to gastric pH; sucralfate works in acid environmentB.The incidence of such bleeding has been decreasingC. The site of hemorrhage is most often in the antrum. - proximal fundus D. There is minimal recurrent bleeding after treatment by oversewing of bleeding sites, vagotomy, and pyloroplasty – superficial bleedingE. Effective surgical treatment necessitates total gastrectomy – only IF not controlled by vagotomy and pyloroplasty

Profuse hemorrhage is 10% the most common manifestationD. Bleeding can generally be managed medically E. Vagotomy is indicated for patients requiring surgical treatment – oversew site of tear no acid reducing operation

5) With regard to Meckel’s diverticula, which of the following
statements are true ?
A. They are found in various anatomic forms and clinical presentations in 50% of the populationB. They are true diverticulaC. All can be visualized on technetium 99m pertechnetate (99mTc) scansD. Most complications occur in the elderlyE. Diverticulitis is the most common complication
Slide 30 of 21
5) With regard to Meckel’s diverticula, which of the following
statements are true ? (B.)
A. They are found in various anatomic forms and clinical presentations in 50% 2% of the populationB. They are true diverticula – antimesenteric border 50cm from IC valve, band to umbilicusC. Some All can be visualized on technetium 99m pertechnetate (99mTc) scans – ectopic gastric mucosa peptic ulcer and bleedD. Most complications occur in the elderly pediatricsE. Diverticulitis bleeding, intussusception, obstruction are is the most common complication – diverticulitis is the least complication. Tx: diverticulectomy for diverticulitis; SBR for bleeding. NO prophylactic diverticulectomy for incidental finding unless gastric mucosa or narrow neck

6) Which is true regarding capsule endoscopy of the SB ?
A. It is a simple, complication free, outpatient procedure that allows examination of the entire length of small intestineB. Capsule endoscopy is not well tolerated by pts since the capsule is attached to a thin wire externalized through the nose to power the device and transmit imagesC. Capsule endoscopy of the SB may be completed in 1 dayD. The capsule endoscope is reusableE. Endoscopic images are viewed using existing endoscopic imaging systems

A. It is a simple, complication free, outpatient procedure that allows examination of the entire length of small intestine – 1.cm in diameter can cause SBOB. Capsule endoscopy is not well tolerated by pts since the capsule is attached to a thin wire externalized through the nose to power the device and transmit imagesC. Capsule endoscopy of the SB may be completed in 1 day - reach colon in 7hrsD. The capsule endoscope is not reusableE. Endoscopic images are viewed using existing endoscopic imaging systems

Intraoperative enteroscopy is a simple, safe technique that eliminates the need for the less sensitive technique of capsule endoscopyD. Push enteroscopy is more sensitive and specific than capsule endoscopy in the area that can be examined by push enteroscopy

7) Which of the following is true regarding SB enteroscopy ? (D.)
A. Capsule endoscopy has replaced push enteroscopy in the evaluation of the SB – enteroscopy only examine 50cm from prox or distal direction miss central SBB. Capsule endoscopy is available only in specialized centers participating in clinical trialsC. Intraoperative enteroscopy is a simple, safe technique that eliminates the need for the less sensitive technique of capsule endoscopy - laparotomyD. Push enteroscopy is more sensitive and specific than capsule endoscopy in the area that can be examined by push enteroscopy

colonic bleeding ?
A. Cancer B. UCC. DiverticulosisD. DiverticulitisE. Angiodysplasia
Slide 36 of 21
8) Which 2 of the following are the most common causes of massive
colonic bleeding ?
A. Cancer – occult bleedB. UC – mild bleedingC. **Diverticulosis ** – ruptured vasa rectaD. Diverticulitis – mild bleedingE. Angiodysplasia – equal frequency with diverticulosis. Aging, intramural muscular hypertrophy obstructs the submucosal veins cause dilatation and bleed

9) A 69 yo M admitted having 3 maroon colored stools. On arrival he passes more bloody stool
and clots. He is pale, orthostatic, and tachycardic. NGT aspirate are bilious. After resuscitation, which is the most appropriate
initial test ? (C.)
A. Angiography – 1 ml/min. #1SMA most bleeds R colon, #2 IMA , #3 celiac. Embolize, 25% rebleed, 5% ischemia/infarction. Vasopressin intra-arterial, cause arrythmia; when stop 30% rebleed.B. Nuclear medicine RBC scan – sulfur colloid cleared rapid. Technetium detect 0.1 ml/min can repeat scanC. Rigid proctoscopy – anorectal source, UC mucosaD. Colonoscopy – not use when bleed briskly. No bowel prepE. BE – barium will obscure angio; not show bleeding
