Effects of previous abdominal surgery incision type on complications and conversion rate in laparoscopic cholecystectomy.

For laparoscopic cholecystectomy, previous abdominal operations are seen as a relative contraindication. 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. Data from 677 patients who had previously undergone abdominal surgery before undergoing laparoscopic cholecystectomy were prospectively collected and evaluated. From the previous operations, the incisions were upper abdominal in 66 patients, lower abdominal in 567, and upper plus lower in 44. Conversion rates in the upper, lower and upper plus lower groups were 27.27%, 2.82%, and 25%, respectively. Intraoperative major complications were bile duct injury (1 patient, upper plus lower incision group), small bowel mesentery injury, and aortic injury (1 patient each, both in the lower incision group). Postoperative major intra-abdominal complications were duodenal injury (1 patient, upper incision group) and small intestine injury (1 patient, lower incision group). The lower abdominal incision group had fewer adhesions in the upper abdomen than did the other 2 groups, and as a result had a much lower conversion rate.
