INTRODUCTION: Natural orifice specimen extraction is the next step in minimally invasive colorectal surgery but can be technically challenging, with additional risks, especially for oncologic surgery. For several key reasons, sigmoid volvulus is well suited for natural orifice specimen extraction surgery. We describe our method and experience with double-stapled anastomosis transrectal natural orifice specimen extraction for sigmoid volvulus.
TECHNIQUE: Using 3- or 4-port laparoscopy, the mesentery is separated from the long sigmoid loop. After the distal bowel is tied off and washed out, the rectum is completely transected and the proximal bowel delivered transrectally through a wound protector. Proximal transection is performed externally, and the circular stapler anvil is set before the bowel is returned into the abdominal cavity. The rectum stump is closed with an endoscopic linear stapler, and a circular-stapled anastomosis is performed.
RESULTS: After successful endoscopic decompression, 6 patients underwent elective laparoscopic sigmoidectomy with natural orifice specimen extraction for volvulus at China Medical University Hospital from 2015 to 2020. The median operative time was 179 minutes (range, 151-236 min). No intraoperative complications were encountered. The median postoperative length of stay was 4 days (range, 2-9 d). One patient experienced postoperative small-bowel ileus resulting in readmission. The median follow-up duration was 12 months (range, 2-49 mo). One recurrence of volvulus was recorded 27 months postsurgery.
CONCLUSION: Uncomplicated sigmoid volvulus can be treated effectively with sigmoidectomy and natural orifice specimen extraction. Surgeons who attempt this procedure should be well versed with conventional laparoscopy but do not necessarily need to be experienced with natural orifice specimen extraction for successful surgery.
