Rupture of mature ovarian cystic teratoma is often secondary to surgical procedures such as laparoscopic ovarian cystectomy, resulting in chemical peritonitis. We use a method of placing a bag under the tumor during laparoscopic ovarian cystectomy (In-Bag method) to prevent chemical peritonitis in our hospital. We retrospectively reviewed laparoscopic ovarian cystectomy performed in our hospital from 2020 to 2023, divided into an In-Bag method group and a Without In-Bag method group. No chemical peritonitis due to spillage of the cyst contents was observed.Compared to the Without In-Bag group, the In-Bag group had significantly shorter operative time (83 minutes vs. 88 minutes) and significantly lower C-reactive protein levels (0.5 mg/dL vs. 0.8 mg/dL). These results suggest that incorporation of the In-Bag method was associated with improved surgical outcomes.
