Objective: This study aimed to assess the surgical outcomes and identify the conversion risk factors of Transvaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) in treating ovarian cyst. Methods: This was a retrospective study of 505 patients who underwent vNO TES for treating ovarian cyst from March 2019 to February 2022 wherein the patients were classified into “converted” or “nonconverted” groups. T-tests, χ2 tests, and logistic regression were used for statistical analyses. Results: There were 16 (3.17 %) surgical conversions and 12 (2.38 %) other surgical complications in our study cohort. Teratomas accounted for 56.8 % of complications in nonconverted cases and 18.8 % in converted cases. Adenocystomas were found in 12.3 % of nonconverted cases and 18.8 % of converted cases. Other types included paraovarian cysts (3.3 % and 0 %), fibroma, granulosa cell tumor, Brenner tumor (1.2 % and 0 %), corpus luteum cysts, follicular cysts (7.6 % and 6.3 %), old abscess (0.2 % and 0 %), and simple cysts (17.6 % and 12.5 %) in the nonconverted and converted groups, respectively. The converted group included more cases of endometriotic cysts (43.8 % vs 12.3 %, p = 0.023), bilateral cysts (37.5 % vs 8.2 %, p
