Colorectal Dis. 2009 Apr 13; Brunner W, Schirnhofer J, Waldstein-Wartenberg N, Frass R, Weiss HAim: On the way to "no-scar" techniques we developed a novel method for colorectal resection utilizing three intraumbilical trocars which results in a non-visible postoperative scar. Methods: Two female patients (Age: 56a, 42a) underwent laparoscopic colorectal resection for diverticulitis and infiltrating endometriosis of the rectosigmoid colon, respectively. The entire operation was carried out transumbilically following the standardized principles of colorectal resection. Results: The operative time was 110min and 180min, respectively. No intraoperative adverse events or significant perioperative complication was noticed. The specimen measured 22cm and 18cm in length respectively. Estimated blood loss was minimal in both cases. Oral diet was resumed on postoperative day 1. Patients were discharged on postoperative day 7 and day 6, respectively. At follow-up patients presented with an optimal cosmetic result without apparent scarring. Conclusions: For the first time a novel laparoscopic technique for sigmoid colon resection utilizing a single intraumbilical approach is presented. This new method allows further reduction of the surgical trauma and obviates any visible scar.
