De Novo Development of Distal Jejunal and Duodenal Adenomas After 41 Months of Teduglutide Treatment in a Patient With Short-Bowel Syndrome: A Case Report.

The glucagon-like peptide-2 (GLP-2) analogue teduglutide is a medical treatment option for patients with short-bowel syndrome-associated chronic intestinal failure. Because studies in mice have shown that GLP-2 analogues may promote the growth of colonic neoplasms, surveillance colonoscopies before and during teduglutide therapy were recommended. The occurrence of small-intestinal neoplasms has not been reported so far, except for a recent report about de novo development of hamartomatous duodenal polyps. We report a case of de novo development of small-intestinal premalignant adenomatous polyps in both bulbar duodenum and distal jejunum in a patient treated with teduglutide for 41 months. Therefore, additional endoscopic surveillance of the upper gastrointestinal tract may be advised during teduglutide therapy for early detection and removal of potential small-bowel adenomas.
