METHODS: A total of 210 patients with bile duct injury occurred during cholecystectomy admitted to Hunan Provincial People’s Hospital from March 1990 to March 2006 were included in this study for retrospective analysis. RESULTS: There were 59.5% (103/173) of patients with IBDI resulting from the wrong identification of the anatomy of the Calot’s triangle during cholecystectomy. The diagnosis of IBDI was made on the basis of clinical features, diagnostic abdominocentesis and imaging findings. Abdominal B ultrasonography (BUS) was the most popular way for IBDI with a diagnostic rate of 84.6% (126/149). Magnetic resonance cholangiography (MRC) could reveal the site of injury, the length of injured bile duct and variation of bile duct tree with a diagnostic rate 100% (45/45). According to the site of injury, IBDI could be divided into six types. The most common type (type 3) occurred in 76.7% (161/210) of the patients and was treated with partial resection of the common hepatic duct and common bile duct. One hundred and seventy-six patients were followed up. The mean follow-up time was 3.7 (range 0.25-10) years. Good results were achieved in 87.5% (154/176) of the patients. CONCLUSION: The key to prevention of IBDI is to follow the "identifying-cutting-identifying" principle during cholecystectomy. Re-operation time and surgical procedure are decided according to the type of IBDI.展开更多

Based on our experience with 600 laparoscopic cholecystectomies, we present a new classification of anatomic variations of the cystic artery, which can be divided into three groups： （1） Calot＇s triangle type, found in 513 patients （85.5%）; （2） outside Calot＇s triangle, found in 78 patients （13%）; （3） compound type, observed in 9 patients （1.5%）.CONCLUSION： Our classification of the anatomic variations of the cystic artery uncontrollable cystic artery extrahepatic bile duct injury. will be useful for decreasing hemorrhage, and avoiding extrahepatic bile duct injury.展开更多

METHODS: A retrospective analysis was performed using 644 consecutive patients who underwent LC from 1991 to 2006. An educational program with the use of IOUS as an operative guide has been used in 276 cases since 1998. RESULTS: IOUS was highly feasible even in patients with high-grade cholecystitis. No BDI was observed after the introduction of the educational program, despite 72% of operations being performed by inexperienced surgeons. Incidences of other morbidity, mortality, and late complications were comparable before and after the introduction of routine IOUS. However, the operation time was significantly extended after the educational program began (P < 0.001), and the grade of laparoscopic cholecystitis (P = 0.002), use of IOUS (P = 0.01), and the experience of the surgeons (P = 0.05) were significant factors for extending the length of operation. CONCLUSION: IOUS during LC was found to be a highly feasible modality, which provided accurate, real- time information about the biliary structures. Theeducational program using IOUS is expected to minimize the incidence of BDI following LC, especially when performed by less-skilled surgeons.展开更多

We present a patient who underwent laparoscopic cholecystectomy for gallstones, in which the biliary injury was recognized intraoperatively. The surgical procedure was converted to an open one. The first surgeon repaired the injury over a T-tube without recognizing the anatomy and type of the biliary lesion, which led to an unusual biliary mal-repair. Immediately postoperatively, the abdominal drain brought a large amount of bile. A T-tube cholangiogram was performed. Despite the contrast medium leaking through the abdominal drain, the mal-repair was recognized intraoperatively. The surgical procedure was converted to an open one. The first surgeon repaired the injury over a T-tube without recognizing the anatomy and type of the biliary lesion, which led to an unusual biliary mal-repair. Immediately postoperatively, the abdominal drain brought a large amount of bile. A T-tube cholangiogram was performed. Despite the contrast medium leaking through the abdominal drain, the mal-repair was unrecognized. The patient was referred to our hospital for biliary leak. Ultrasound and cholangiography was repeated, which showed an unanatomical repair （right to left hepatic duct anastomosis over the T-tube）,with evidence of contrast medium coming out through the abdominal drain. Eventually the patient was subjected to a definitive surgical treatment. The biliary continuity was re-established by a Roux-en-Y hepaticojejunostomy, over transanastomotic external biliary stents. The patient is now doing well 4 years after the second surgical procedure. In reviewing the literature, we found a similar type of injury but we did not find a similar surgical real-repair. We propose an algorithm for the treatment of early and late biliary injuries.展开更多
