Laparoscopically assisted ovarian cystectomy with totally enclosed protective device for tumor isolation

To present a novel totally enclosed protective device for tumor isolation in laparoscopic ovarian cystectomy.

A retrospective study was conducted of 16 patients with unilateral ovarian teratoma in the Department of Obstetrics and Gynecology of the China-Japan Friendship Hospital. Laparoscopic surgery was performed with a totally enclosed protective device for tumor isolation, followed by a case series retrospective study. The indexes measured included size of cyst, rate of intraoperative rupture, duration of operation, amount of intraoperative blood loss, and postoperative length of stay in the hospital. An intact cyst resected in the device with no spillage seen indicated a successful surgery.

A total of 16 operations were performed successfully. The mean diameter of the cysts was 7.2 ± 1.4 cm. Of them, 12 (75%) had an intraoperative cyst rupture without spillage. The mean duration of surgery was 1.3 ± 0.1 h and the mean amount of intraoperative blood loss was 12.5 ± 3.2 ml. All postoperative histology tests showed benign cysts. The mean length of stay after surgery was 2.4 ± 0.5 days. No peritonitis-related symptoms or complaints were reported.

Laparoscopically assisted ovarian cystectomy with a totally enclosed protective device for tumor isolation was confirmed safe and feasible.
