Strategy and technique of laparoscopic common bile duct exploration.

The laparoscopic approach to common bile duct exploration enables the complete clearance of stones from the bile duct without damage to structures of physiological importance such as the ampulla of Vater. Despite preoperative endoscopic retrograde cannulation of the biliary tree (ERCP) in patients with suspected stones, routine intraoperative cholangiography reveals a further 6% with unsuspected common bile duct stones. Both the preoperative suspected stone and the stone found on intraoperative cholangiography can be adequately managed by the laparoscopic method. The approach to the common bile duct via the cystic duct avoids incising the common duct or the sphincter of Oddi. The common bile duct can be approached satisfactorily by balloon dilatation of the cystic duct to 5 mm so enabling the choledochoscope to be inserted into the common bile duct. Small stones are washed into the duodenum or extracted by the Segura basket retrogradely through the cystic duct. Larger stones can be disintegrated by laser or electrohydraulic lithotripsy; the fragments can either be washed into the duodenum or sucked out via the cystic duct. Laparoscopic choledochotomy is indicated for multiple big or proximally located stones. The larger sized Segura basket can be used effectively for these large stones. Residual stones are extracted under cholangioscopic control and any incarcerated stone disintegrated by lithotripsy. A small catheter placed in the common bile duct or a standard T-tube completes the exploration and avoids disordered function of the sphincter of Oddi.(ABSTRACT TRUNCATED AT 250 WORDS)

[Apropos of a case of acute pancreatitis revealing cystic dilatation of the common bile duct].

Dilatation of the common bile duct is rarely caused by cystic formations. Though the pathogenesis is uncertain, congenital disorders have been suggested. Most cases are observed in small children (80% female predominance) with only 20% of the cases reported in adults. Clinical signs vary. Recurrent acute pancreatitis has been reported but is rare. New imaging techniques using CT-scan cholangiography and sometimes MR cholangiography have greatly improved the diagnostic approach. MR of the bile ducts is a recent noninvasive technique enabling an analysis of the biliopancreatic ducts without contrast injection into the bile. To our knowledge, cystic dilatation of the common bile duct has not been previously reported in the literature. We report an interesting case in a 25-year-old woman who developed an episode of acute pancreatitis during the post partum period. We describe the clinical aspects and the different imaging findings, including magnetic resonance cholangiography results.

Does routine cystic duct cholangiogram during laparoscopic cholecystectomy prevent common bile duct injury?

Between November 1989 and September 1992, the author performed 1,000 laparoscopic cholecystectomies. Three common bile duct injuries occurred (0.3%). Selective cystic duct cholangiograms were performed for diagnosis and management of common bile duct stones. A total of 102 cholangiograms (10%) were done. Only eight of these cholangiograms were done for anatomical verification in the face of severe chronic or acute cholecystitis. Five were cystic duct cholangiograms, resulting in two common bile duct injuries. To avoid the problem of common bile duct injury in cases of obscure anatomy where clarification was needed, a cholecystocholangiogram was done for duct identification in three subsequent cases without event. The third common bile duct injury occurred early in the learning experience without benefit of the cholangiogram.

Post-traumatic ischemic necrosis of the common bile duct.

A case of blunt injury to the extrahepatic bile ducts is reported. The injury was more likely caused by ischemia than by forces acting directly on the ducts. When disruption occurs at the time of injury, its recognition may be delayed considerably, because the leaked bile is encapsulated or remains sterile and is therefore well tolerated. When there is ischemia without disruption, as in the case presented, perforation due to necrosis may also take some time (days to weeks) to occur. In the interval, loss of appetite, nausea, vomiting, abdominal distension and jaundice may develop. Bile-stained ascitic fluid is present.

Carcinoma of the cystic duct protruding into the common bile duct: report of a case.

We report herein the case of 65-year-old man in whom a diagnosis of primary carcinoma of the cystic duct was made on the basis of Farrar's criteria. The patient was admitted with upper abdominal pain, and although there was no evidence of jaundice or a palpable mass, there was tenderness in his right upper quadrant. Carcinoma of the cystic duct was suspected on the basis of computed tomography and magnetic resonance imaging findings. Cholecystectomy with resection of the bile duct and lymph node resection was performed, and percutaneous transhepatic cholangiography revealed a filling defect in the common bile duct (CBD). The tumor was found to have arisen from the cystic duct and demonstrated papillary growth into the CBD intraluminally through the orifice of the cystic duct. Microscopically, the tumor was identified as papillary adenocarcinoma with invasion limited to the subserosal layer of the cystic duct. There were no signs of nodal metastasis.

Management of common bile duct stones.

Management of common bile duct stones has changed rapidly as new developments in surgical and endoscopic equipment have become available. Prior to advanced laparoscopic surgical techniques and endoscopic sphincterotomy, common bile duct stones required open surgery, choledochotomy, and manual removal. New alternatives in the management of choledocholithiasis must be understood to allow for comprehensive management of common bile duct stones. Endoscopic and surgical techniques can also be combined for excellent results utilizing minimally invasive techniques. The appropriate choice of therapy will depend on the experience and the resources available.

Benign disease of the common bile duct.

The incidence of common bile duct (CBD) pathology in a group of patients with benign biliary disease (n = 505) was found to be 23.2 per cent. The spectrum included 111 patients (90.2 per cent) with CBD stones, 37 of whom (33.3 per cent) had no symptoms or findings pre-operatively indicating CBD involvement. Five patients had papillary stenosis, three had postoperative CBD strictures, one had a choledochal cyst and one had an external biliary fistula. Of the 100 CBDs measuring more than 10 mm in diameter, 90 harboured calculi. In the remaining 23 CBDs measuring less than 10 mm, calculi were present in 21. The presence of CBD calculi was demonstrated by intra-operative cholangiography in 49 patients. In the remaining patients (n = 74), the diagnosis of CBD pathology was made either by percutaneous transhepatic cholangiography, endoscopic retrograde cholangio-pancreatography, T-tube cholangiography or peroperative palpation. The surgical procedures performed included choledochotomy and T-tube drainage (n = 74), transduodenal sphincteroplasty (n = 27) and choledochoduodenostomy (n = 18). The overall mortality and morbidity of CBD exploration was 3.3 per cent and 24.4 per cent respectively, which was significantly greater than that for cholecystectomy alone (0.3 per cent and 8.6 per cent respectively). Transduodenal sphincteroplasty carried a much higher mortality (11 per cent) and morbidity (52 per cent) when compared with other procedures.

Gastroduodenal regulation of common duct bile flow in the dog.

We investigated the relationship between the entry of individual drops of bile into the duodenum and gastroduodenal motor activity in the fasted state in 10 conscious dogs. The common bile duct was transected and a catheter was inserted through each end. The exteriorized catheters were connected to a photometric drop-flow meter. During phase III activity, bile entered the duodenum in single drops, only in between two consecutive contractions, or as a series of drops during transient inhibition of duodenal contractions by antral phase III contractions. During phase II activity bile also entered the duodenum, usually in between contractions or when the duodenum was intermittently quiescent. Bile entered the duodenum during a duodenal contraction only when the contraction amplitude was less than 15% +/- 1% (mean +/- SE) of the maximal amplitude during phase III contractions. Bile flow into the duodenum showed a cyclic pattern with a peak during late duodenal phase II activity and a trough during duodenal phase I activity only when phase III activity originated in the duodenum and migrated caudad. There was no cyclic pattern of bile flow when phase III activity originated in the proximal jejunum and migrated caudad. The total volume of bile flow in a migrating motor complex cycle and bile flow rate were greater when phase III activity started in the proximal jejunum than when it started in the duodenum. We conclude that gastroduodenal contractions play an important role in the regulation of bile flow into the duodenum. The cyclic pattern of bile flow is altered when phase III activity starts ectopically in the jejunum.

[Management of common bile duct stones--Results of a nationwide survey with analysis of 8 433 common bile duct explorations in Germany].

BACKGROUND: Aim of this study was the evaluation of the management of choledocholithiasis and outcome of laparoscopic as well as open cholecystectomy in Germany. METHODS: A written questionnaire was sent to 449 randomly selected German surgeons annually from 1991 to 1994 and additionally to all German university hospitals until 1998. RESULTS: A total of 98 482 operations for gallstone disease including 86 485 cholecystectomies (non-university hospitals 1991-1993: n = 60 246, university hospitals 1991-1996: n = 26 239) and 8 433 common bile duct (CBD) explorations (non-university hospitals: n = 6 919, university hospitals: n = 1 514) with or without cholecystectomy were reported. The overall complication rate for CBD explorations was 13.2 % (non-university hospitals) and 15.1 % (university hospitals), the overall hospital mortality rate was 0.64 % (non-university hospitals) and 0.58 % (university hospitals, n. s.). When choledocholithiasis was suspected, in 1998 all university hospitals used a two-stage management with preoperative ERC. In case of diagnosed isolated choledocholithiasis 93 % usually chose an endoscopic approach. When simultaneous cholecysto-choledocholithiasis was diagnosed preoperatively 86 % of the university hospitals used a two-stage management with preoperative ERC and stone extraction and secondary cholecystectomy (1991: 45 %). The percentage of CBD explorations decreased continuously from 7.4 % in 1991 to 3.8 % in 1996 (p < 0.01). CONCLUSION: These results allow for the estimation of frequency and overall risks in surgical therapy of CBD stones. At the moment, laparoscopic CBD exploration does not play a significant role in Germany. Data show a trend to the two-stage "therapeutical splitting" with lower complication rates.

Delayed common bile duct obstruction in acute pancreatitis.

Common bile duct obstruction during acute pancreatitis usually occurs in the early symptomatic phase of the illness, involves only the distal portion of the common bile duct, and subsides with clinical improvement. We present two cases of persistent common bile duct obstruction that developed 2-3 months after complete clinical subsidence of the initial episode of severe acute pancreatitis and involved a long segment of the common bile duct. After surgical decompression, there was no recurrence of common bile duct obstruction or pancreatitis.
