Insufflation techniques in gynecologic laparoscopy.
Our objectives were to assess the safety and efficacy of different insufflation methods in women undergoing laparoscopy and to develop a model for selection of the appropriate insufflation technique based on the patient's characteristics and surgeon's experience. We performed a retrospective analysis of laparoscopic procedures on 3086 women over a 13-year period at the University of Louisville Hospital, Louisville, KY. All laparoscopic procedures were performed on an outpatient basis by residents under faculty supervision. Five different insufflation techniques were evaluated: standard transumbilical insufflation, open laparoscopy, transuterine insufflation, subcostal insufflation, and direct trocar insertion technique. Body mass index and previous abdominal surgeries were identified as the most important factors in the selection of the most successful insufflation method based on the surgeon's experience, using data mining techniques. During the first insufflation attempt, we were successful at achieving a pneumoperitoneum 94.7% of the time. This number increased to 98.1% when we switched to a second alternative insufflation method. In all, there were 5 complications out of 3086 patients (0.16%) after all insufflation techniques.
