Transfundal insertion of a Veress needle in laparoscopy of obese subjects: a practical alternative

Because induction of artificial pneumoperitoneum through the infra-umbilical route is associated with complications in laparoscopic procedures, especially in obese patients, we performed a prospective randomized study comparing the conventional infra-umbilical route with a transfundal route, in which the Veress needle is inserted into the peritoneal cavity through the uterine fundus. One hundred obese subjects (body mass index >/=25 kg/m(2)) scheduled for laparoscopic sterilization were randomized into two groups. In the infra-umbilical group pneumoperitoneum was achieved at a ratio (punctures/pneumoperitoneum) of 56/49 (1.14). There was one failure in this group. In the transfundal group the ratio was 53/51 (1.04). There was no clinically significant bleeding in either of the groups; nor were there any major complications. One subject in whom the infra-umbilical route failed was moved to the transfundal group. This subject also underwent dilatation and curettage at the time of laparoscopy. Postoperatively she contracted chlamydial pelvic inflammatory disease. No other infections were detected postoperatively in either of the groups. In conclusion, the transfundal route of inducing artificial pneumoperitoneum proved to be easy, safe and effective.
