The purpose of this study was to investigate the effects of the incision type of previous abdominal surgery on laparoscopic cholecystectomy in terms of complications and conversion to open surgery. From among the previous operations, the incisions were upper abdominal in 40 patients and lower abdominal in 193. Conversion rates was one case (1.7 percent). Intraoperative major complications were bile duct injury (0.4 percent, small bowel injury (0.8 percent), gallbladder injury (11.6 percent) and bleeding (7.7 percent). The lower abdominal incision group had fewer adhesions in the upper abdomen than did the upper abdomen. In conclusions, previous abdominal surgery is not a contraindication to safe laparoscopic cholecystectomy. However, previous upper abdominal surgery is associated with a prolonged operation time.
