37. Cefoperazone concentrations in bile and gall bladder wall after intravenous administration.
Cefoperazone concentrations in the common duct bile, gall bladder bile, and gall bladder wall were determined in four patients with cholelithiasis and one patient with carcinoma of the head of the pancreas, all of whom had normal renal functions. Within 65 min after a 1-g intravenous administration, maximum concentrations ranged from 373.4 to 3,100 microgram

38. Solitary cystic dilatation of the intrahepatic bile duct.
A 31 year old man was hospitalised with general fatigue and epigastric pain. Abdominal ultrasonography, computed tomography, and magnetic resonance imaging showed a cystic lesion in the left lobe of the liver. Endoscopic retrograde cholangio-pancreatography and percutaneous trans-hepatic cholangiography revealed a localised dilatation of the intrahepatic bil

39. Prospective randomised study of preoperative endoscopic sphincterotomy versus surgery alone for common bile duct stones.
One hundred and twenty patients with known common bile duct stones were entered into a prospective randomised study of preoperative endoscopic sphincterotomy and stone clearance (group 1) versus surgery alone (group 2). Five patients were incorrectly entered; the 55 patients randomised to group 1 and the 60 randomised to group 2 were well matched with respec

40. Innervation of the gall bladder and biliary pathways in the guinea-pig.
The innervation of the gall bladder and the biliary pathways was studied in guinea-pigs by means of histochemical methods for catecholamines and for acetylcholinesterase on whole mount preparations, on cryostat sections and on sections of plastic-embedded tissues. The gall bladder contains on average 367 neurons in a ganglionated plexus which lies at the out

41. Selective cholangiography. Current role in laparoscopic cholecystectomy.
The initial 22-month experience with laparoscopic cholecystectomy in 400 patients employing an algorithm of selective cholangiographic evaluation is reported. Preoperative or postoperative endoscopic retrograde cholangiography was performed whenever stones were suspected clinically. Preoperative endoscopic retrograde cholangiography was performed in 44 patie

42. Towards T-tube free laparoscopic bile duct exploration: a methodologic evolution during 300 consecutive procedures.
OBJECTIVE: To establish a simple, reproducible, and safe technique of laparoscopic common bile duct exploration (CBDE) with high clearance rates and low morbidity and mortality rates. SUMMARY BACKGROUND DATA: For most general surgeons, laparoscopic CBDE appears an unduly complex and demanding procedure. Since the introduction of laparoscopic cholecystectomy,

43. Technique and results of biliary reconstruction using side-to-side choledochocholedochostomy in 300 orthotopic liver transplants.
OBJECTIVE: The authors evaluated the complication rate and outcome of side-to-side common bile duct anastomosis after human orthotopic liver transplantation. SUMMARY BACKGROUND DATA: Early and late biliary tract complications after orthotopic liver transplantation remain a serious problem, leading to increased morbidity and mortality. Commonly performed tech

44. Prediction of common bile duct stones by noninvasive tests.
OBJECTIVE: To define accurate and useful predictors of common bile duct stones (CBDS). SUMMARY BACKGROUND DATA: The ability to predict CBDS with noninvasive tests can avoid unnecessary, costly, or risky procedures. METHODS: All patients referred for examination for CBDS by endoscopic ultrasonography (EUS) from 1993-1996 were prospectively entered in a databa

45. Biliary levels of ceforanide.
Ceforanide levels in plasma, gallbladder bile, gallbladder tissue, and common bile duct were studied in 10 patients with normal biliary tracts and in 35 patients with biliary disease at various intervals after intravenous injection of 1 g of the drug. Peak blood levels were obtained within 1 h of administration (mean, 67 +/- 15 micrograms/ml). Patients with

46. Laparoscopic antegrade sphincterotomy. A new technique for the management of complex choledocholithiasis.
OBJECTIVE: Laparoscopic antegrade sphincterotomy represents a new technique that expands the ability of the surgeon to manage complex choledocholithiasis at the time of laparoscopic cholecystectomy. The authors describe their experience with six patients with cholelithiasis and complex common bile duct stone disease who underwent successful laparoscopic chol

47. Rapid increase in plasma levels of atrial natriuretic peptide after common bile duct ligation in the rabbit.
Previous studies have shown that common bile duct ligation in the rabbit is followed by a reduction of the extracellular water compartment. To further elucidate the mechanisms leading to volume depletion in this model, water and sodium balances and changes in plasma concentrations of atrial natriuretic peptide (ANP), vasopressin (ADH), plasma renin activity

48. Laparoscopic cholecystectomy and common bile duct stones. The utility of planned perioperative endoscopic retrograde cholangiography and sphincterotomy: experience with 63 patients.
OBJECTIVE: Planned perioperative endoscopic retrograde cholangiography (ERC) and sphincterotomy (ES) for suspected or proven common bile duct stones (CBDS) has been attempted in 63 of 540 consecutive patients undergoing laparoscopic cholecystectomy (LC). Experience with this intervention has been studied with respect to accuracy, efficacy, and safety. SUMMAR
