Transvaginal endoscopic surgery-assisted versus conventional laparoscopic adnexectomy (TVEA vs. CLA): A propensity-matched study and literature review

Abstract Objective Natural orifice transluminal endoscopic surgery (NOTES) may be useful in gynecologic endoscopic surgery. This study evaluated the efficacy, safety, and perioperative outcomes of combined NOTES and vaginal approach, transvaginal endoscopic surgery-assisted adnexectomy (TVEA), for the surgical treatment of presumed benign ovarian tumors. Materials and methods Records were reviewed for 33 consecutive TVEA procedures performed between May 2011 and March 2014. Patient age, body mass index, parity, mass size, and mass bilaterality were used to select comparable patients who had undergone conventional laparoscopic adnexectomy (CLA). Results A total of 236 patients were included in this study (203 CLAs and 33 TVEAs). No cases switched to abdominal laparotomy. Operating time and length of postoperative stay were significantly longer in the CLA group than in the TVEA group, while total hospital charges were higher in the TVEA group ( p conclusion TVEA can be safely performed for benign and large ovarian tumors. In addition, TVEA offers superior operative efficiency compared to CLA.
