Iatrogenic colorectal perforation during therapeutic colonoscopy is a rare but serious complication [1]. It is usually managed with immediate open surgery. However, conservative therapy has recently been advocated [2], provided that adequate precolonoscopic bowel preparation has been carried out and that no peritoneal signs are present [3]. Asymptomatic perforations after colonoscopic polypectomy have been conservatively managed using close observation, even in the presence of intra-abdominal free air [4]. Recently, endoclip closure was used to treat iatrogenic colonic perforation conservatively [5]; however, endoclipping cannot be used to repair perforations that are larger than the endoclip (diameter 11 mm) [5].

We report the case of a large iatrogenic rectal perforation due to endoscopic mucosal resection (EMR) and its subsequent conservative treatment.

A 65-year-old woman with a flat 30-mm-wide rectal adenoma underwent EMR after injection of 0.4 % sodium hyaluronate ([Fig. 1 a]).

Fig. 1 a A flat, 30-mm-wide rectal adenoma underwent endoscopic mucosal resection. b An approximately 25-mm-wide perforation was noted at the mucosectomy site, and the marginal mucosa of the perforation was circumferentially attached to the tissue adjacent to the rectum using endoclips. c Closure of the perforation was confirmed 10 days later.

The lesion was completely removed; however, a 25-mm-wide perforation was noted on the posterior wall at 10 cm from the anal verge. The perforation was too large to be closed by endoclipping, so the marginal mucosa of the perforation was circumferentially attached to the presacral tissue adjacent to the rectum using endoclips ([Fig. 1 b]). Computed tomography (CT) revealed free air in the presacral space, but no pneumoperitoneum ([Fig. 2 a]).

The patient was asymptomatic and her general status was stable. Therefore, conservative treatment was instituted, with intravenous antibiotic injections and discontinuance of oral nutrition. On the next day, the patient’s white blood cell count and C-reactive protein level were normal; the amount of free air observed on CT had not increased ([Fig. 2 b]). Proctoscopy revealed closure of the perforation 10 days later ([Fig. 1 c]), and the patient was discharged on day 16. At 2 years after EMR she has had no further complication. The resected specimen was 38 mm wide, and the pathological diagnosis was tubulovillous adenoma (diameter 30 mm; [Fig. 3]).
