Chronic hemolysis predisposes adults with sickle cell disease (SCD) to the formation of bilirubinate cholelithiasis. To study the impact of laparoscopic cholecystectomy (LC) on this groups, we reviewed our records of all patients with SCD and cholelithiasis treated electively from 1991 to 1999. During that period, 13 consecutive patients with SCD underwent(More)
BACKGROUND With the evolution of laparoscopic cholecystectomy (LC) as the standard operation for benign gallbladder disease, the role of endoscopic retrograde cholangiopancreatography (ERCP) in the management of common bile duct (CBD) stones has to be defined. METHODS From November 1990 to April 1994 we attempted LC in 1,788 patients. Eighty-nine patients(More)

The concentrations of nitrate, nitrite, N-nitroso compounds and bacteria were measured in 96 samples of fasting gastric juice, pH 0.90-8.50, obtained from 56 individuals just before or at various times (8 days - 1 year) after gastric operation. The mean pH of the post-operative samples [4.66 +/- 0.39 (SEM)] was significantly higher than that of the(More)
