Objective. To report a technique for securing specimens during laparoscopic procedures. Measurements and Main Results. As it frequently would be convenient to retain small specimens in the abdomen until a later stage of laparoscopy, a technique was developed to help prevent loss of specimens. A suture is placed through the specimen and the port is removed. Free ends of the suture are held with a clamp outside the abdomen while the port is reinserted into the abdomen. The suture is pulled in order to visualize the specimen when necessary. Conclusion. This technique of suture placement acting as a leash adds an insignificant amount to surgical time, but saves time wasted locating a misplaced specimen.

Objective. To describe the electrosurgical resection ablation (ERA) resectoscope sleeve. Measurements and Main Results. By testing modified rollerball electrodes in vitro and in vivo, technology has developed modified rollerball electrodes to be used for endometrial ablation. In vitro studies were performed in extirpated uteri to test safety, efficacy, and endometrial destruction by serially incrementing unmodulated current power from what was considered minimum (150 W) to maximum effect (300 W). The electrodes were used similarly in women just before hysterectomy and after uterine extirpation. Tissue damage was evaluated by histopathologic examination. Conclusion. New electrodes can destroy endometrium and superficial portions of myometrium, and will permit use of the ERA resectoscope sleeve with saline or electrolyte-containing solutions.
184. Radially Expanding Access System Is Setting

Objective. To describe experience with radially expanding access system. Measurements and Main Results. In a series of over 1000 women involving several centers and physicians, the radially expanding system was a safe, convenient, and fast access device. Two prospective studies reported diminished pain with this system compared with conventional cannulas. Conclusion. With a diminished residual defect requiring no fascial closure, the radial expanding access arm relieves the surgeon of one small but often difficult procedure at the end of a case.

Objective. To evaluate feasibility of the see-and-treat approach to endometrial polyps. Measurements and Main Results. From March 1997 to February 1998,739 diagnostic hysteroscopies were performed in 103 women, and endometrial polyp was diagnosed. In 67 (65%) patients the polyp appeared smaller than 2 cm. We removed these polyps with microforceps through a 5.5-mm operative sheath. If polyps were larger, the surgical procedure was postponed and resectoscopy was performed under local anesthesia with paracervical block. In 39 women
Objective. To describe the Hermes operating room control system. Measurements and Main Results. Hermes is a voiceactivated, surgeon-specific control system for laparoscopic operating room equipment. It includes camera, light source, VCR, video printer, insufflator, and robotic ann (AESOP). Ultimately, it will include more
