Introduction Colonoscopy is a safe and effective procedure, but it is also an inevitably invasive one. Laparoscopic repair of colonoscopic perforations has been reported to be a safe and effective treatment. Aim We present our surgical technique and outcomes of laparoscopic repairs using an endoscopic linear stapler for iatrogenic colonic perforation during screening colonoscopy. Material and methods Laparoscopic repair using an endoscopic linear stapler for iatrogenic colonic perforation during screening colonoscopy was performed by two experienced laparoscopic surgeons on 14 consecutive patients between April 2010 and December 2017 at our hospital. Using prospectively collected data, an observational study was performed on a per protocol basis. Results The mean age of the 14 patients who underwent laparoscopic repair was 56.6 ±9.1 years. The most common perforation site was the sigmoid colon in 10 (71.4%) patients, followed by the rectosigmoid junction in 3 (21.4%) patients and the splenic flexure in 1 (7.1%) patient. The median perforation size was 10 (range: 5-30) mm. The mean operation time was 73.9 ±28.2 min. Postoperative complications occurred in 1 (7.1%) patient. There was no postoperative mortality or reoperation within 30 days after surgery. The median time to tolerance of a regular diet was 5 (range: 3-6) days. The median postoperative hospital stay was 8.5 (range: 5-15) days. Conclusions Laparoscopic repair using an endoscopic linear stapler is a safe, easy, and effective surgical technique to treat colonic perforation related to screening colonoscopy.
