Discoid Resection of Rectosigmoid Endometriotic Nodules

Abstract

Study ObjectiveTo show various techniques to perform laparoscopic anterior discoid resection of rectosigmoid endometriotic nodules. DesignA step-by-step explanation of the techniques using video with narration (educational video). SettingSegmental bowel resection and reanastomosis are treatment options for larger rectosigmoid endometriotic nodules. However, laparoscopic anterior discoid resection of rectosigmoid endometriotic nodules is feasible and potentially less morbid in the appropriate candidate. Detailed knowledge of the avascular planes of the pelvis, particularly the pararectal and rectovaginal spaces, is crucial when approaching these nodules, which may initially present within an obliterated posterior cul-de-sac. Resection begins with determination of the nodule size followed by enucleation of the nodule itself. A 2-layer closure with barbed suture is then performed using a rectal probe as a template. Our institution previously demonstrated that barbed suture is safe to use in bowel repair and did not result in major complications [1]. An air leak test assesses the integrity of the repair and may be completed with air insufflation or with a methylene blue or povidone-iodine enema. With larger nodules, a V-shaped closure may be necessary. The patients provided consent to use images and videos of the procedure. Institutional review board approval was not required for this procedure. InterventionsLaparoscopic anterior discoid resection of a rectosigmoid endometriotic nodule. ConclusionLaparoscopic anterior discoid resection avoids the need for segmental bowel resection and reanastomosis. Barbed suture is a safe option for 2-layer bowel closure [1].
