Abstract:

Objective　To explore anatomic features of posterior Calot's triangle and its clinical significance in laparoscopic cholecystectomy（LC）.　Methods　The clinical data of 217 patients with acute cholecystitis underwent LC by using three trocars in our hospital from Aug. 2004 to Oct. 2010 were retrospectively analyzed.　Results　Of the patients，LC was successfully completed in 202 cases (93.2% )，however, 10 cases (4.6%) were converted to open surgery， 5 cases complicated with common duct stones were cured by ERCP.  No biliary injury，bile leak or hemorrhage occurred in this series. Postoperative surgical drainage was performed according to the operating conditions. The patients were discharged from hospital in 2-12 days (averagely 4.5 days). No complication was found during a 6-month follow-up in 193 cases. Conclusions　It is safe and feasible to perform LC by using three trocars for treating acute cholecystitis, especially for those with severe tissue adhesion in posterior Calot's triangle.
