Over-The-Scope-Clip pre-mounted onto a double balloon enteroscope for fast and successful closure of post-EMR jejunal perforation: case report

BACKGROUND Familial adenomatous polyposis (FAP) is a rare, autosomal dominant disease clinically characterized by the early onset of many adenomatous polyps throughout the colon, which turn into colon cancer, if left untreated. In FAP patients, polyps can also occur in the upper gastrointestinal (GI) tract, especially in the duodenum. Adenomas beyond duodenum are rare and mostly located in the proximal jejunum and distal ileum. The management of such polyps can be either surgical or endoscopic, depending on the features of the polyp, Spigelman stage and patient's clinical conditions. Endoscopic mucosal resection (EMR) of jejunal polyps can be challenging, because of the thinner wall of jejunum, compared to the rest of the GI tract, and of the difficulty of maintaining control and stability of the scope. For these reasons, jejunal perforation is a likely occurrence. CASE PRESENTATION A 65-year-old woman with a stage IV FAP, who had previously undergone abdominal surgery because of her disease, came to our attention because of numerous adenomatous-looking duodenal polyps and a 25 mm lesion in proximal jejunum. According to Spigelman staging system, patient was candidate for surgical resection, in light of the risk of developing small bowel cancer. Despite the benefits of surgery were clearly explained to her, she refused to undergo small bowel resection. Therefore, EMR of the largest duodenal polyp and of the jejunal lesion was planned. After the removal of the jejunal polyp, a small perforation was noted. We were able to rapidly close such perforation by using the Over-The-Scope-Clip system (OTSC, 12/6 t; Ovesco, Tübingen, Germany) pre-mounted onto a double balloon (DB) enteroscope. CONCLUSIONS The endoscopic management of jejunal perforation can be tricky and the placement of traditional through-the-scope clips in a narrow space like jejunum may be difficult and time consuming. This case describes the use of the OTSC system pre-mounted onto a DB enteroscope for the closure of post-EMR jejunal perforation.
