A simple modification of choledochoenterostomy using continuous pull through suture.

A simple modification of choledochoenterostomy is described. Using continuous suture and pull through technique, the posterior line of the anastomosis is completed without immediate approximation of the two structures. By improving the access, good control of the posterior suture line is ensured, the risk of anastomotic leakage is minimized and the use of stent or T tube is unnecessary.

Iatrogenic bile duct injuries. The real incidence and contributing factors--implications for laparoscopic cholecystectomy.

Laparoscopic cholecystectomy has achieved wide acceptance as the preferred treatment for symptomatic gallbladder disease. Yet there are alarming reports of iatrogenic bile duct injuries. To establish a comparison standard, the incidence of iatrogenic bile duct injury during conventional cholecystectomy has to be known. A single institutional retrospective review of 1,617 consecutive open cholecystectomies between 1980 and 1989 was performed. Eight patients (0.49%) sustained iatrogenic bile duct injury in this study. Inflammation, anatomic variation, or both were contributing factors in all injuries. Operative cholangiography identified the injury at the initial operation in three patients. Treatment consisted of either primary ductal repair, ductal repair over a stent, or ductal-enteric anastomosis. There were no late complications after surgery (follow-up 26 to 97 months; mean 50.9 months). The implications for laparoscopic cholecystectomy are apparent. Iatrogenic bile duct injuries are associated with acute inflammation and/or variant ductal anatomy; routine operative cholangiography assumes increased importance; and immediate repair of the injury minimizes long-term complications.

Iatrogenic extrahepatic bile duct injury in 182 patients: causes and management.

OBJECTIVE: To describe the causes and treatment of iatrogenic bile duct injury caused by cholecystectomy. METHODS: 182 patients with iatrogenic extrahepatic bile duct injury from 4 university hospitals of China were reviewed. Details of primary cholecystectomy, biliary reconstruction as well as postoperative management were recorded. All patients were followed up for at least 6 months (6 months to 9 years, median 3.5 years). The adequacy of repair was assessed by regular evaluation of the patients' clinical status and liver function variables. Hepatobiliary B-ultrasonography was used routinely in the follow up of patients, and magnetic resonance cholangiopancreatography was applied in the patients suggestive of abnormality. RESULTS: In 152 patients, bile duct injury happened during open cholecystectomy, and in 30 patients during laparoscopic cholecystectomy. All the injuries developed during anterograde cholecystectomy (at the Calot's triangle). All the patients with these injuries underwent choledochocholedochostomy or Roux-en-Y choledochojejunostomy with good results (161 patients), recurrent stricture (11), and death (10). CONCLUSIONS: During cholecystectomy, the Calot's triangle should be identified anatomically, but retrograde cholecystectomy is the optimal choice. Bile duct injury should be discovered as soon as possible and be managed timely. Different operative methods are optional according to the degree of injury and the postoperative period.

[Clinical significance of endoscopic sphincterotomy compared with surgical common bile duct exploration and surgical sphincterotomy].

Records of 940 patients with endoscopic sphincterotomy (ES) and 100 patients with choledochotomy for stone removal were compared. Those with ES were characterized by older mean age (65.9 vs. 60.6, p < 0.001), similar frequency of operative risks (36% vs. 45%), and a less complication rate (8.2% vs. 53%, p < 0.001) as compared with the surgery group. Complications of ES included cholangitis, pancreatitis, bleeding, and basket impaction. One patient each with cholangitis and pancreatitis died, thus a mortality rate of 0.2%. Complications of choledochotomy occurred in 53 patients with no death. Most of them were associated with anesthesia, laparotomy, wound and immobilization. The complications of ES should decrease due to recent development of lithotripsy instruments and endoscopic stenting to prevent cholangitis. Follow-up of 74 patients 15-21 years after surgical sphincterotomy revealed recurrent stones in 3.5%, which was lower than a recurrence rate of 10.3% in 290 patients 5-14 years after ES. However, that rate may be an underestimate, because the follow-up was obtained in only 79% of those with surgical sphincterotomy as compared with 99% of ES. Ninety percent of those with recurrence after ES underwent endoscopic treatments again, whereas 10% had surgery. Easy repetition at the time of recurrence is one of major advantages of the endoscopic treatment.

[Diagnosis and management of benign biliary strictures with percutaneous transhepatic cholangioscopy (PTCS)].

From January 1981 through March 1991, we encountered twenty four cases of benign biliary strictures. In 10 cases of anastomotic stricture, percutaneous dilatation was carried out in 1 patient under fluoroscopy and in 3 patients under PTCS without recurrence. Endoprosthesis with silicone or polyurethane catheters was carried out under PTCS in 5 patients. One of them died of hepatic failure due to clogging of the catheter, and in other four patients the endoprosthetic catheter was dislodged spontaneously or removed by PTCS because of dislodgement or obstruction of the catheter, and PTCS revealed that the anastomotic stricture had improved. Reoperation of cholangiojejunostomy was carried out in 1 patient, who died of hepatic failure 5 years later due to recurrent of stricture. In 8 cases of the iatrogenic and 1 case of traumatic stricture, percutaneous dilatation was carried out (1 under fluoroscopy and 4 under PTCS) without recurrence. Cholangiojejunostomy was carried out in 3 cases without anastomotic stricture. PTCS was performed for 5 cases of the inflammatory stricture of the hepatic hilus due to cholecystitis to confirm the histological findings by cholangioscopic biopsy. And all cases could be managed by cholecystectomy. Authors recommend that PTCS should be used for the diagnosis and treatment of benign biliary stricture.

Anomalous pancreaticobiliary junction: image analysis and treatment principles.

BACKGROUND: Anomalous pancreaticobiliary junction is often associated with biliary tract carcinoma and acute pancreatitis. We assessed the value of image analysis in the diagnosis of patients with anomalous pancreaticobiliary junction (APBJ) and the principles for the treatment of APBJ. METHODS: Sixty-four patients with APBJ were subjected to ultrasound imaging, endoscopic retrograde cholangiopancreatography (ERCP) and magnetic resonance cholangiopancreatography (MRCP) before surgery. The diagnostic accuracy of image analysis and their surgical outcomes were evaluated retrospectively. RESULTS: On ERCP and MRCP, the length of the common channel was calculated to be 15 mm or longer in all patients, and the angle of the junction was more than 75 degree in 49 (76.6%) of the 64 patients. Of the 64 patients, 28 were defined of pancreatic duct type (P-C) (28/64, 43.75%), 32 bile duct type (C-P) (32/64, 50%), and 4 common channel type (4/64, 6.25%). CONCLUSIONS: Patients with APBJ are often associated with biliary tract and pancreatic diseases, and early detection and correct surgical treatment could avoid serious complications. ERCP and MRCP are accurate in the diagnosis of APBJ.

Surgical treatment of hepatic hydatid disease.

The results of surgery in 38 patients with hepatic hydatid disease are described. Cystectomy was done in four patients with small peripheral cysts. For them the mean postoperative stay was 8.2 days. Partial cystectomy, introflexion and omentoplasty were performed in 28 patients with uncomplicated large cysts. The mean postoperative stay for these patients was 8.6 days. One patient in this group died of massive hemorrhage and disseminated intravascular coagulation. Exploration of the common bile duct and choledochoduodenostomy were required in three patients who had large cysts complicated by rupture into the biliary tree. This complication resulted in a mean postoperative stay of 11.5 days. Three patients who had cysts complicated by pyogenic infection were treated with tube drainage. They were discharged with their tubes in place after a mean hospital stay of 26.5 days. Hydrogen peroxide 10% was used as a scolicidal agent and was successful in preventing dissemination. All patients underwent ultrasonography 3 months after surgery, and 28 (74%) were followed up by annual examination. There was no recurrence after a mean follow-up of 2.7 years. The results suggest that surgical treatment of hepatic hydatid disease should be governed by the size, location and complications of the cyst. The combination of partial cystectomy, introflexion and omentoplasty was safe and effective therapy for patients with large hepatic cysts uncomplicated by pyogenic infection.
