摘要
To analyze patient safety in laparoscopic ovarian tissue transplantation surgery by tracking the rate of postoperative complications and the learning curves of the surgeons by statistical process control analysis.A retrospective study.A university-affiliated hospital.A total of 100 patients with premature ovarian insufficiency who underwent ovarian tissue cryopreservation by vitrification and then autologous transplantation of frozen-thawed ovarian tissues with in vitro activation.Ovarian tissue cryopreservation, in vitro activation, and transplantation.We assessed the surgery complications, differences in total surgery time, transplantation time, and transplantation time per ovarian sheet in operations performed by 3 experienced laparoscopic surgeons. Surgeon A performed 80 operations; surgeon B, 29 operations; and surgeon C, 20 operations. Complications occurred in 1.55% of the procedures. Although all 3 surgeons' performance never fell below the unacceptable failure limit, only surgeon A became competent after 66 cases.The laparoscopic ovarian tissue transplantation surgery was generally safe given that the postoperative complications were infrequent (1.55%). Although the performance of all 3 surgeons was acceptable, only surgeon A attained the level of competency after 66 cases. The transplantation method may not be the key factor for reducing surgery time in this surgery. An efficient ovarian tissue transplantation team is more important in reducing the surgery time than the surgeon's surgical technique alone.
