Extra-hepatic biliary-ductal necrosis in acute pancreatitis: a rare complication.

An 8-year-old male presented with an acute abdomen. Exploration revealed bilious ascites, oedematous pancreatitis with areas of necrosis, and omentum showing patches of fat necrosis. The common bile duct and almost all of the common hepatic duct were gangrenous and had sloughed, with bile leaking from the junctional stump of the right and left hepatic ducts. The patient was managed successfully by Roux-en-Y hepaticojejunostomy. This is a rare case showing necrosis and sloughing of the extrahepatic bile ducts in acute pancreatitis.

Effect of diazepam sedation on arterial oxygen saturation during esophagogastroduodenoscopy: a placebo-controlled study.

OBJECTIVE: To determine the effect of sedation using diazepam on hemoglobin oxygen saturation (SpO2) in patients undergoing esophagogastroduodenoscopy (EGD). METHOD: 100 consecutive patients scheduled for EGD were randomly allocated to receive 0.03 mL/Kg of either diazepam (5 mg/mL solution) or normal saline intravenously after topical oropharyngeal anesthesia immediately before the procedure. SpO2 was continuously monitored throughout the procedure by an anesthetist who was unaware of the drug received. RESULTS: Fall in SpO2 exceeding 4% was noted in 78% of patients in the diazepam group and in 38% of patients in the placebo group (p < 0.001). Fall in SpO2 to suboptimal level (89%) was seen in 20% of patients in the diazepam group and in 10% patients in the placebo group (p < 0.001). The duration of suboptimal SpO2 was similar (means +/- SD being 2.47 +/- 0.10 min in diazepam group and 2.86 +/- 0.32 min in placebo group). CONCLUSION: Intravenous diazepam administration before EGD produces a significant fall in SpO2 during the procedure, and so should be avoided; continuous monitoring of SpO2 should be done during EGD.

Jejunal diverticulosis.

Diverticulosis of the jejunum is an uncommon condition. We found four patients with such diverticula among 40,341 hospital admissions. All four patients presented with acute volvulus of the small bowel. It is suggested that the diverticula bearing segment becomes heavier due to the diverticula and the semisolid jejunal contents consisting of roughage, millet and cereals in the staple diet of our patients. Both factors contribute to small bowel volvulus. Jejunal diverticula may be missed because they are buried between the leaves of mesentery or adherent loops of jejunum. With a patient has vague abdominal symptoms, the possibility of jejunal diverticula should be considered.
