To induce pneumoperitoneum for laparoscopic examination, a transvaginal route and a modified Verres needle were used in an effort to reduce the failure rate of the subumbilical route and to avoid some of its dangers. The technic not only reduces the rate of complications, but its precision and simplicity make it easier to learn and execute.
