preoperative imaging diagnosis
Laparoscopic cholecystectomy becomes one of the standard procedures for digestive surgeons. There is consensus that careful dissection and correct elucidation of the anatomy avoids the complications during cholecystectomy. From May 1991 to March 2005, 433 cases of laparoscopic cholecystectomy were retrospectively analyzed. Conversion to open cholecystectomy was required in 19 cases（4.4%）and the rate of vascular injury or bile duct injury was 0.7% each. CT angiography was effective for preoperative evaluation of vascular anatomy. In many cases, middle hepatic vein was located near gallbladder bed. CT cholangiography was also useful for obtaining information of the biliary tract. Careful evaluation of preoperative CT angiography and cholangiography contributes to decrease the risk of complications during laparoscopic cholecystectomy.
