Laparoscopic surgery recently has been conducted to repair colonic perforation that is associated with colonoscopy. The authors describe their laparoscopic repair of perforation using passing sutures and an endoscopic linear stapler. One 12-mm and several 5-mm trocars were inserted in the lower abdomen under general anesthesia. Observing with a laparoscope, passing sutures were threaded transversely through all layers of the margin of defect and pulled up with forceps to hold the margin straight, along which the defect was stapled with an endoscopic linear stapler. The authors applied this method for five patients, where the perforation occurred in the sigmoid colon or in the cecum (perforation size ranging from 10 mm to 50 mm). Perforation was successfully repaired in all patients, with no complications because of perforation or the procedures. The current method is beneficial because the perforated lesion is safely and easily closed and postoperative colonic stenosis is avoided.
