Adenocarcinoma at a strictureplasty site in Crohn's disease: report of a case.

Strictureplasties have proven useful and safe in Crohn's disease. Concerns have been raised, however, about the potential of carcinoma arising at the strictureplasty site. Here the authors report a case of a small-bowel adenocarcinoma developing at the site of a prior strictureplasty in a middle-aged male patient seven years postoperatively in the absence of any other preneoplastic disease of the small bowel. Presenting symptoms were of progressive obstruction after a long period of quiescent disease. With this report comes stronger evidence that adenocarcinoma does occur at strictureplasty sites, raising questions of its long-term safety.
