Abstract:
We here report a case of endoscopy-assisted partial duodenal resection for duodenal adenoma in a patient with familial adenomatous polyposis(FAP). A male underwent total proctocolectomy with ileal pouch anal anastomosis in 1997. Since 2004, duodenal adenomas occurred and the atypical grade of adenoma was gradually aggravated. Therefore, he underwent endoscopy-assisted partial duodenal resection in 2013. The pathological finding of the specimen showed well-differentiated tubular adenocarcinoma(pM, ly0, v0). No recurrence has been observed at 4 years after the operation. Endoscopy-assisted partial duodenal resection was minimum invasive surgery and considered to be useful for the patients with duodenal adenoma.
