Background: Effect of duration of cholecystectomy on orocecal transit time and small intestinal bacterial overgrowth in gallstone patients is poorly understood. Method: 128 gallstone patients of either sex, aged between 25-68 years were enrolled. 79/128 followed after 4-6 months of cholecystectomy. 49 patients had undergone cholecystectomy 2 15years before study and reported gastrointestinal sy...

Altered hepatic cholesterol metabolism has been implicated in the etiology of cholesterol gallstones. This hypothesis has been examined by determining acyl-coenzyme A:cholesterol acyltransferase (ACAT) activity in liver biopsies from 31 cholesterol gallstone patients and 12 control subjects. Hepatic ACAT activity in gallstone patients was decreased to one-third that in controls (P less than 0.0...

Gallstone ileus is an uncommon cause of small bowel obstruction. We present a case of small intestinal obstruction owing to a large gallstone in lower ileum in a 65 years old man. The diagnosis was made by computed tomography.

HYPOTHESIS Endoscopic retrograde cholangiopancreatography (ERCP) is frequently used preoperatively in adult patients with suspected choledocholithiasis. Cholelithiasis occurs much less often in children, and the indications for ERCP are not established. We hypothesized that the natural history of choledocholithiasis in children is spontaneous passage of stones through the papilla and that these...

Gallstone ileus is a rare disease that accounts for 1-4% of intestinal obstructions. Almost exclusively a condition in the older female population, it is a difficult diagnosis to make. We report the case of gallstone ileus in a 94-year-old Caucasian female, who presented to the emergency department with acute-onset nausea, coffee-ground emesis, lack of bowel movement, and abdominal distension. ...

Gallstone pancreatitis was first recognized as an entity by Opie in 1901 (1), and since then has generated volumes of literature which have attempted to explain its pathophysiology. Multiple animal experiments and human clinical studies in the past thirty years have led to a better understanding of both macro- and microscopic events which lead to pancreatic inflammation in the setting of a pass...

This paper describes an ongoing eeort to verify the cache coherence protocol of the IEEE/ANSI Standard for Scalable Coherent Interface using the Mur' veriication system. A model of the typical set protocol was constructed in the Mur' description language. This model was augmented with a speciication of properties necessary for cache coherence. The Mur' veriication system automatically checks if...

We investigate the neutral Higgs sector of the minimal supersymmetric standard model in explicit CP violation scenario. Within the context of the effective potential formalism, the masses of the neutral Higgs bosons at the one-loop level are calculated by taking into account the contributions of the following loops of ordinary particles and superpartners: top quark, the scalar top quarks, botto...

Cholesterol gallstones are one of the most prevalent and most costly digestive diseases in the developed countries. Although precipitation of cholesterol from supersaturated bile is the first irreversible physical-chemical step in cholesterol gallstone formation, hepatic hypersecretion of biliary cholesterol is the primary defect in the formation of cholesterol gallstones. The other common abno...

Gallstone spillage is a common intraoperative event during laparoscopic cholecystectomy (LC). Patients present months to years with nonspecific symptoms after the original procedure. The complications of retained peritoneal gallstones are infrequent. Having a high index of suspicion is the key to early diagnosis. Every effort should be made to remove spilled gallstones at the index operation to...
