The study aims to develop instruments and a hemostasis system via a 7–11 mm trocar‑sheath to enable effective endoscopic intra‑abdominal surgery. The authors evaluated new laparoscopic techniques in over 2,000 procedures from 1973–1976 and expanded them in 1977 to include myomectomy, adnectomy, ovarian cyst resection, cystomectomy, and tubectomy for tubal pregnancy. In 115 cases no intra‑ or postoperative complications occurred, and normal healing was confirmed in follow‑up procedures, demonstrating that the new equipment and techniques ushered in a new era of gynecologic surgery.
The development of suitable instruments for perfect grasping, cutting, sucking, ligating and of a new system of performing hemostasis by endocoagulation through a 7–11 mm Ø trocar-sheath enables us to initiate effective endoscopical intraabdominal surgery. New surgical techniques are being investigated on > 2.000 cases of surgical pelviscopic interventions which were performed between 1973-1976. Since 1977 we have extended the endoscopical intraabdominal surgery as follows: Myomectomy (subserous), adnectomy, ovarian-cyst-resection, cystomectomy, tubectomy in case of tubal pregnancy. In 115 cases no intra- or postoperative complications have occurred. Normal postsurgical healing procedure could be checked on 18 re-pelviscopies and on 2 later laparotomies. The new technical equipment has opened us together with special surgical procedures a new era of gynecologic surgery.
