title: Triluminal hybrid NOS as a novel approach for colonic resection with colorectal anastomosis.
abstract: BACKGROUND
  Minimal invasive surgery has led to a significant decrease in surgical trauma, pain, recovery time and improved cosmesis compared with open surgery. However, scar development and the risk of hot spots for infections and hernias are still present. Natural orifice surgery (NOS) promises to offer even further reduction in invasiveness and thus may lead to even faster recovery. The goal of this study was to establish a NOS colonic resection by using commercially available standard surgical instruments avoiding major abdominal incisions.
  
  
  RESULTS
  This article reports a new triluminal hybrid NOS approach for sigmoid and colonic resection (Tri-Port-NOS-SIG), established using rigid laparoscopic instruments through the umbilicus, the vagina, and the rectum, without any major abdominal incision. The specimen was retrieved through the anus avoiding dilatation of the vagina. In an early series of 5 patients the first patient was a 37-year-old woman with a 10-year history of recurrent diverticulitis. She recovered quickly and was discharged on postoperative day 2. She returned to sports activity on day 12 postoperatively and to her heavy-duty job on day 16. The following 4 patients also recovered well and were discharged on postoperative days 7 (2 patients), 8, and 11, respectively. One patient experienced a temporary, mild paresthesia of the left lower dorsal leg, most likely because of intraoperative positioning. No major complications occurred.
  
  
  CONCLUSIONS
  Tri-Port-NOS-SIG offers a feasible scarless approach for abdominal resections using commercially available surgical instruments in experienced hands.
