Robotic Colostomy Takedown in a Patient with Extensive Ventral Hernias and Adhesive Disease.

To demonstrate a surgical video wherein a robot-assisted colostomy takedown was performed with anastomosis of the descending colon to the rectum after reduction of ventral hernias and extensive lysis of adhesions. Case report and a step-by-step video demonstration of a robot-assisted colostomy takedown and end-to-side anastomosis. Tertiary referral center in New Haven, Connecticut. A 64-year-old female was diagnosed with stage IIIA endometrioid endometrial adenocarcinoma in 2015 when she underwent an optimal cytoreductive surgery. In addition, she required resection of the sigmoid colon and a descending end colostomy with Hartmann's pouch, mainly secondary to extensive diverticulitis. After adjuvant chemoradiation, she remained disease free and desired colostomy reversal. Body mass index at the time was 32 kg/m Enterolysis was extensive and took approximately 2 hours. The splenic flexure of the colon had to be mobilized to provide an adequate proximal limb to the anastomosis site. An anvil was then introduced into the distal descending colon through the colostomy site. A robotic stapler was used to seal the colostomy site and detach it from the anterior abdominal wall. Unfortunately, the 28-mm EEA sizer (Covidien, Dublin, Ireland) perforated through the distal rectum, caudal to the stricture site. A substantial length of the distal rectum had to be sacrificed secondary to the perforation, which mandated further mobilization of the splenic flexure. The rectum was then reapproximated with a 3-0 barbed suture in 2 layers. This provided us with approximately 6- to 8-cm distal rectum. An end-to-side anastomosis of the descending colon to the distal rectum was performed. Anastomotic integrity was confirmed using the bubble test. Because of the lower colorectal anastomosis, a protective diverting loop ileostomy was performed. The patient had an uneventful postoperative course. A hypaque enema performed 3 months after the colostomy takedown showed no evidence of anastomotic leak or stricture. The ileostomy was then reversed without any complications. Robot-assisted colostomy takedown and anastomosis of the descending colon to rectum were successfully performed. Although there is a paucity of literature examining this technique within gynecologic surgery, the literature on general surgery has supported laparoscopic Hartmann's reversal and has demonstrated improved rates of postoperative complications and incisional hernia and reduced duration of hospitalization [1]. Minimally invasive technique is a feasible alternative to laparotomy for gynecologic oncology patients who undergo colostomy, as long as the patients are recurrence free.
