Congenital absence of the gall-bladder is a rare condition. It is sometimes associated with other congenital defects. We report here two cases of gall-bladder agenesis discovered at laparoscopy. Both had a history of skeletal and cardiovascular anomalies. The investigation of patients with absent gall-bladder can be very difficult. Ultrasound scanning is usually inconclusive and further noninva...

Gall bladder storage of hepatic bile prevents complete recovery of biliary excretion of drugs to be obtained under physiological conditions in man. The aim of this study was to develop and validate a method for simultaneous measurement of gall bladder storage of a cholephilic drug, and of its duodenal excretion and t1/2 in bile. Duodenal perfusion using polyethylene glycol as intestinal recover...

Endoscopic sphincterotomy with extraction of the stones is often the only treatment for stones in the bile duct in patients considered unfit for surgery. Most of these patients fare well even when they have stones in the gall bladder; cholecystectomy for biliary colic, acute cholecystitis, or jaundice was necessary in less than 15% followed up for up to seven years. 2 After the procedure patien...

Gall-bladder duplication is a rare anatomical variation, which can affect safe performance of cholecystectomy and be a cause of persistent symptoms and a need for reoperation in case of accessory gall-bladder omission. A case of successfully performed elective laparoscopic cholecystectomy in a patient with duplicated gall-bladder accidentally intraoperatively disclosed is presented. The identif...

Studies in animals have suggested a neural reflex between the gall bladder and the sphincter of Oddi. The aim of this study was to investigate whether sphincter of Oddi motility is altered by distension of the gall bladder in humans. Sphincter of Oddi motility was recorded intraoperatively in 10 patients undergoing elective cholecystectomy for gall stones. The manometry was performed by a tripl...

Laparoscopic cholecystectomy can be performed using instruments even smaller than 3 mm in diameter and with two, three or four ports, depending on the choice of the operating surgeon. In any of these techniques of laparoscopic cholecystectomy, the gall bladder is usually removed through the umbilical port. This requires repositioning of the instruments and reorientation. Using the standard four...

Gall bladder mucocele (GBM) may currently represent the most common indication for surgical management of extra-hepatic biliary tract disease in dogs. It has not yet been convincingly described in cats. The underlying lesion has been described as cystic mucosal hyperplasia. Hypersecretion of mucus progressively leads to an accumulation of gelatinous bile within the gall bladder lumen. Increased...

We studied gall bladder contractility in 61 children with beta-thalassaemia who were asymptomatic for gall bladder disease and 51 sex- and age-matched controls in Cairo, Egypt, using, andreal-time ultrasonography. Multiple gall bladder stones were present in 18.0% of thalassaemia patients and sludge in 6.6%. There were statistically significant differences between thalassaemia patients controls...

OBJECTIVE To provide reference ranges of the fetal gall bladder in the Korean population. MATERIALS AND METHODS Fetal gall bladder development was evaluated in well-dated, non-anomalous fetuses in the Korean population between February and April 2003 and the visualization rate and reference values were determined from the obtained data. RESULTS The visualization rate of the fetal gall bladd...

We have carried out overnight measurements of hepatic secretion rate and duodenal output of biliary lipids using a duodenal perfusion technique. We correlated these measurements with the fasting state mass of biliary lipids within the gall bladder on the following morning using a combined nasoduodenal intubation and isotope scanning technique. We studied six gall stone subjects before and durin...
