Risk Factors for Morbidity and Mortality in Acute Gastrointestinal Hemorrhage • Age >60 yr • Comorbid disease • Renal failure • Liver disease • Respiratory insufficiency • Cardiac disease • Magnitude of the hemorrhage • Systolic blood pressure <100 mm Hg on presentation • Transfusion requirement • Persistent or recurrent hemorrhage • Onset of hemorrhage during hospitalization • Need for surgery

5) With regard to Meckel’sdiverticula, which of the following statements are true ? (B.) A. They are found in various anatomic forms and clinical presentations in 50% 2% of the population B. They are true diverticula – antimesenteric border 50cm from IC valve, band to umbilicus C. Some All can be visualized on technetium 99m pertechnetate (99mTc) scans – ectopic gastric mucosa peptic ulcer and bleed D. Most complications occur in the elderly pediatrics E. Diverticulitisbleeding, 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 intestine B. 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 images C. Capsule endoscopy of the SB may be completed in 1 day D. The capsule endoscope is reusable E. Endoscopic images are viewed using existing endoscopic imaging systems
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 intestine – 1.cm in diameter can cause SBO B. 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 images C. Capsule endoscopy of the SB may be completed in 1 day - reach colon in 7hrs D. The capsule endoscope is not reusable E. Endoscopic images are viewed using existing endoscopic imaging systems

7) Which of the following is true regarding SB enteroscopy ? (D.) A. Capsule endoscopy has replaced push enteroscopy in the evaluation of the SB – enteroscopyonly examine 50cm from prox or distal direction miss central SB B. Capsule endoscopy is available only in specialized centers participating in clinical trials C.

8) Which 2 of the following are the most common causes of massive colonic bleeding ? A. Cancer – occult bleed B. UC – mild bleeding C. **Diverticulosis ** – ruptured vasa recta D.

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.

Rigid proctoscopy – anorectal source, UC mucosa D. Colonoscopy – not use when bleed briskly. No bowel prep E. BE – barium will obscure angio; not show bleeding
