Transumbilical Single-Port Laparoscopic Cystectomy of Giant Ovarian Teratoma

Abstract

Mature ovarian teratomas are benign germ cell tumors of the ovary, accounting for about 10 % -20 % of ovarian tumors and 95 % of ovarian teratomas. Mature ovarian teratomas are common in young women. They are usually unilateral, slow growing, cystic, mobile, smooth, with little or no ascites. Ovarian cystectomy for benign neoplasms instead of oophorectomy is mandatory for ovarian function preservation. We report a case of a large pelvic teratoma in a 19-year-old adolescent female, approximately 20.7cm×10.5cm in size. The patient's main clinical presentation was mild lower abdominal pain, After transumbilical single-port laparoscopic ovarian cystectomy, the final histopathological report was bilateral ovarian mature teratoma. This case report suggests that transumbilical single-port laparoscopic-assisted in vitro giant ovarian tumor ablation is a safe and feasible surgical approach for patients with benign large adrenal tumors. it effectively combines the advantages of open surgery and laparoscopic resection of large ovarian tumors, which not only protects ovarian function, but also avoids cyst fluid overflow and has significant postoperative cosmetic effects. Nevertheless, this study also had some limitations. First, this was a case report and not a multi-center randomized controlled trial. Second, it included a single patient and the short follow-up data precluded us from deriving any conclusions about the long-term efficacy and safety of this method.
