Single incision laparoscopic sigmoid colon resections without visible scar: a novel technique.

Objective: On the way to 'no-scar' techniques we developed a novel method for colorectal resection utilizing three intraumbilical trocars which results in a nonvisible postoperative scar.

Method: 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.
