Impact of routine intraoperative cholangiography during laparoscopic cholecystectomy on bile duct injury.

BACKGROUND: The role of intraoperative cholangiography (IOC) in the diagnosis, prevention and management of bile duct injury (BDI) remains controversial. The aim of the present study was to determine the value of routine IOC in the diagnosis and management of BDI sustained during laparoscopic cholecystectomy (LC) at a high-volume centre. METHODS: A retrospective analysis of a single-institution database was performed. Patients who underwent LC with routine IOC between October 1991 and May 2012 were included. RESULTS: Among 11,423 consecutive LCs IOC was performed successfully in 95.7 per cent of patients. No patient had IOC-related complications. Twenty patients (0.17 per cent) sustained a BDI during LC, and the diagnosis was made during surgery in 18 patients. Most BDIs were type D according to the Strasberg classification. The sensitivity of IOC for the detection of BDI was 79 per cent; specificity was 100 per cent. All injuries diagnosed during surgery were repaired during the same surgical procedure. Two patients developed early biliary strictures that were treated by percutaneous dilatation and a Roux-en-Y hepaticojejunostomy with satisfactory long-term results. CONCLUSION: The routine use of IOC during LC in a high-volume teaching centre was associated with a low incidence of BDI, and facilitated detection and repair during the same surgical procedure with a good outcome.

Bile duct injuries: management of late complications.

BACKGROUND: Laparoscopic cholecystectomy is the treatment of choice for gallbladder stones. In the current study, this approach was associated with a higher incidence of biliary injuries. The authors evaluate their experience treating complex biliary injuries and analyze the literature. METHODS: In a 15-year period, 169 patients with bile duct injuries (BDIs) resulting from open and laparoscopic cholecystectomies were treated. The patients were retrospectively evaluated through their records. Biliary injury and associated lesions were evaluated with imaging studies. Surgical management included therapeutic endoscopy, percutaneous interventions, hepaticojejunostomy, liver resection, and liver transplantation. Postoperative outcome was recorded. Survival analysis was performed with G-Stat and NCSS programs using the Kaplan-Meier method. RESULTS: Of the 169 patients treated for BDIs, 148 were referred from other centers. The injuries included 115 lesions resulting from open cholecystectomy and 54 lesions resulting from laparoscopic cholecystectomy. A total of 110 patients (65%) fulfilled the criteria for complex injuries, 11 of whom met more than one criteria. Injuries resulting from laparoscopic and open cholecystectomies were complex in 87.5% and 72% of the patients, respectively. The procedures used were percutaneous transhepatic biliary drainage for 30 patients, hepaticojejunostomy for 96 patients, rehepaticojejunostomy for 16 patients, hepatic resection for 9 patients, and liver transplantation projected for 18 patients. Hepaticojejunostomy was effective for 85% of the patients. The mean follow-up period was 77.8 months (range, 4-168 months). The mortality rate for noncomplex BDI was 0%, as compared with the mortality rate of 7.2% (8/110) for complex BDI. Mortality after hepatic resection was nil, and morbidity was 33.3%. The actuarial survival rate for liver transplantation at 1 year was 91.7%. CONCLUSIONS: Complex BDIs after laparoscopic cholecystectomy are potentially life-threatening complications. In this study, late complications of complex BDIs appeared when there was a delay in referral or the patient received multiple procedures. On occasion, hepatic resections and liver transplantation proved to be the only definitive treatments with good long-term outcomes and quality of life.
