RecruitingCombination productUltrasound Evaluation for Improving Patient Selection in vNOTESVaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) is an emerging field in minimally invasive surgery. International consensus-based statement was recently published to help guide the basis for adopting vNOTES into clinical practice, including regarding patient selection. It was agreed that women with potential adhesions are not appropriate candidates for vNOTES approach including women with suspected adhesions due to history of severe pelvic inflammatory disease (PID) or endometriosis. However, as some pelvic infections might be asymptomatic, pre-operation imaging might be beneficial to complete improved selection of patients. Moreover, women with previous severe PID or endometriosis might still have favorable pelvic to perform the vNOTES approach. Therefore, we aim to compare pre-operation ultrasound evaluation to operative characteristics and outcomes in women undergoing VNOTES approach surgery.
