Color coding of sutures in laparoscopic perforated duodenal ulcer: a new concept.

A simple modification for securing the omental patch during laparoscopic oversewing of perforated duodenal ulcers is presented. This new concept uses color coding of sutures to prevent confusion and suture "cut-out" during the tie-over of the omental patch. The concept of suture color-coding may be applicable to other laparoscopic procedures where identification of "suture pairs" is difficult.
