Laparoscopic cholecystectomy is the treatment of choice for gallstone disease. The ultrasonogram has failed for the early detection of gallbladder cancer, especially if inflammation (chronic or acute) is present. Incidental gallbladder could be an important cancer finding during laparoscopic cholecystectomy, due to the potential cancer cell dissemination(More)
The indications for routine intraoperative cholangiography remain controversial. We present here our recent results concerning the frequency of unknown retained common bile duct stones in 253 consecutive patients who underwent laparoscopic cholecystectomy without intraoperative cholangiography in whom the presence of preoperative choledocholithiasis had(More)
BACKGROUND Bile leakage is more common after laparoscopic cholecystectomy than after open surgery. In our department, the rate of postoperative bile collections after open surgery is 0.2% vs 0.6% after laparoscopic cholecystectomy. METHODS We studied 13 cases of intraperitoneal bile collection without common bile duct damage drawn from a total of 5,200(More)
Laparoscopic cholecystectomy is currently the standard procedure for chronic and acute cholecystitis. The purpose of this prospective study was to evaluate the preoperative ultrasound findings of the gallbladder and correlate those aspects with surgical videoscopic and histopathologic findings and the results concerning intraoperative complications and the(More)
Background: Bile leakage is more common after laparoscopic cholecystectomy than after open surgery. In our department, the rate of postoperative bile collections after open surgery is 0.2% vs 0.6% after laparoscopic cholecystectomy.

Resting common bile duct pressure was measured in three groups of patients: group 1, 53 patients with gallstones but without common duct stones; group 2, 35 patients with common bile duct stones unaccompanied by cholangitis; and group 3, 36 patients with common duct stones and acute suppurative cholangitis. A significantly higher pressure in the common bile(More)
Knowledge of congenital anomalies in abdominal viscera is important for surgeons, if they are to treat such patients and solve their problems adequately. This article presents an unusual case of reversed rotation of the intestine associated with anomalies in the biliary tract and gallbladder. This patient underwent surgery because of a bleeding duodenal(More)
The purpose of this prospective controlled study was to determine the changes in intraluminal pressure and diameter of the common bile duct in a total of 121 bile patients with choledocholithiasis, and the consequences of these alterations for choledochal mucosa and liver histology. In fact, the reflux of bacteria from the obstructed biliary tract into the(More)
BACKGROUND Endoscopic band ligation is the treatment of choice for bleeding esophageal varices. However it is not clear if this procedure is associated with less early and late mortality than sclerotherapy. AIM To assess rates of re-bleeding and mortality in cohorts of patients with bleeding esophageal varices treated with endoscopic injection or band(More)
