Abstract
Video Objective To evaluate the efficacy of air pressure device in laparoscopic ovarian endometrioma removal for ovarian wound hemostasis and the significance of ovarian function protection. Setting A prospective study in university hospital. Interventions We developed the air sac device and patented it. After the cyst removed, we placed the air sac pressure device into the pelvic cavity through the right trocar. And then we pumped the air into the sac through a three port valve. When the sac flowed up, the air in sac created air pressure to the wound surface of the ovary. The pressure was kept for 6-10 minutes to stop the bleeding. In 5 cases, the bleeding on ovarian wound surface was inhibited effectively, and the electric coagulation was reduced greatly. Conclusion The application of air sac hemostasis device in laparoscopic cystectomy could stop the bleeding effectively and then reduce the electric coagulation greatly. This may avoid the excessive heat damage to ovarian tissue.
