Abstract: Objective：To research short-outcome and effect on pregnancy after sparing-fertility surgery of the borderline ovarian tumors (BOTs) with laparoscopy or laparotomy approach. Methods：Clinic-pathologic variants of 74 sparing-fertility cases with BOTs from January 2009 to July 2015 in the Tianjin Central Hospital of Obstetrics & Gynecology were analyzed retrospectively. 44 cases and 30 cases were carried out laparoscopic surgery and laparotomy surgery respectively. Recurrence and pregnancy of two groups were compared. Results：Age of laparotomy group was younger than that of laparoscopic group significantly (P=0.018). Maximal longitude of tumor in laparotomy group was significantly longer than that of the laparoscopic group (P=0.000). Number of unstaging cases in laparoscopic group were significantly more than that of laparotomy group (P=0.000). Total recurrent rate was 6.7% (5/74). There were no significant differences of recurrent rate between the two groups (P=0.980). The total pregnant rate was 33.8% (25/74) in sparing-fertility patients, 30% (9/30) in laparotomic group, 36.4% (16/44) in the laparoscopic group with insignificant difference between two groups (P=0.570). The pregnancy rate of unstaging cases in laparoscopic group was significantly higher than that of laparotomy group (P=0.041). No recurrence occurred in pregnant cases. Conclusions：Short-outcome and pregnancy of BOTs patients with unstaging laparoscopic sparing-fertility surgery were satisfactory. It was safe and feasible to undergo laparoscopic sparing-fertility surgery in selectable patients with BOTs.
