3-port laparoscopic D3 right hemicolectomy with transvaginal natural orifice specimen extraction - A Video Vignette

Vaginal natural orifice transluminal endoscopic surgery (vNOTES) right hemicolectomy with intracorporeal anastomosis for cecal cancer

Vaginal natural orifice transluminal endoscopic surgery (vNOTES) for colorectal cancer utilizes transvaginal access for bowel mobilization, vascular pedicle ligation, oncological resection, and bowel anastomosis, along with subsequent transvaginal natural orifice specimen extraction (NOSE), reducing or eliminating the need for transabdominal access. In this report, we describe the technique of vNOTES right hemicolectomy for cecal cancer, with intracorporeal anastomosis and transvaginal NOSE, including a step-by-step operative video. The patient was a 59-year-old Chinese female (body mass index 32.0 kg/m2) with a cT3N0M0 3 cm cecal adenocarcinoma. Posterior colpotomy was created with insertion of a dual-ring wound protector. vNOTES D2 right hemicolectomy with a fully stapled intracorporeal anastomosis was performed via a homemade transvaginal glove port, using extra-long rigid instruments. A 10 mm, 30° rigid laparoscope was used for operative visualization through a transumbilical port, without additional percutaneous trocars. Operative difficulties pertained to suboptimal instrument reach, lack of triangulation, and frequent clashing within the restricted access space. Surgical duration was 300 min, with 50 ml of blood loss. There was minimal postoperative pain. Return of bowel function occurred on postoperative day 2, with discharge from hospital on postoperative day 3. The patient resumed normal daily activities and regular diet by 1-week post-surgery. Self-reported cosmetic satisfaction score was excellent. No operative complications were observed at 2 months' follow-up. vNOTES right hemicolectomy with intracorporeal anastomosis is safe and feasible in highly selected colon cancer patients. Operators should be proficient in conventional laparoscopic colectomy and transvaginal NOSE. More experience with the vNOTES technique is required to ascertain best practices.
