['To compare the risk of major complications during the set-up procedures for laparoscopy according to whether the classic technique (creation of the pneumoperitoneum followed by introduction of the optics trocar) or open laparoscopy is used.', 'Comparison was made of two retrospective series each carried out in a department promoting one of the two techniques. The setting was a university-affiliated hospital. Two groups of patients were compared: group A, classic laparoscopy, n = 8324; group B, open laparoscopy, n = 1562. We investigated the set-up procedures of operative laparoscopy according to the rules of classic or open laparoscopy.', 'The risk of failure requiring conversion to laparotomy is significantly higher in the group of patients who underwent open laparoscopy [three cases (0.19%) vs. 0 case (0.0%); p = 0.004]. The risk of major complications is comparable in the two groups [group A, four cases (0.05%) vs. group B, three cases (0.19%); p = 0.08]. In the classic laparoscopy group there were four major complications: one injury to the aorta and three bowel injuries. In the open laparoscopy group there were three major complications: two bowel injuries and one postoperative occlusion.'] Does complications during set-up procedures for laparoscopy in gynecology : open laparoscopy reduce the risk of major complications?
