Advanced duodenal adenomatosis in patients with familial adenomatous polyposis (FAP) is associated with a significant risk of duodenal carcinoma. Duodenectomy is sometimes indicated to prevent malignant transformation or to resect established carcinomas. Advanced recurrent adenomatosis and cancer formation in the neo-duodenum after duodenectomy in FAP have been reported. The aim of this study was to describe findings during endoscopic follow-up in a cohort of FAP patients after duodenectomy, to assess the indication and whether recommendations can be made for endoscopic surveillance. All FAP patients with a history of duodenectomy performed at a single tertiary referral centre between January 2000 and July 2011 were identified. Patient characteristics and postoperative upper endoscopic procedures were reviewed retrospectively. 19 patients, with a mean age of 49 years at the time of duodenectomy were identified. One patient was lost to follow-up. The majority of patients underwent prophylactic pancreas preserving duodenectomy (95%). Mean duration of postoperative follow-up in 18 patients was 78 months with 4 postoperative endoscopies on average. An increase in neo-Spigelman stage was seen in 9 patients, after an average interval of 35 months. Overall, newly formed adenomas in the neo-duodenum were found in 14 of 18 patients (78%), after a mean of 46 months after duodenectomy. Recurrent adenomas were mostly located in close proximity to the neo-papilla. This included advanced adenomas in 7 patients, warranting enteric re-resection in 2 patients. Continued intensive endoscopic surveillance is indicated after duodenectomy in FAP, especially of the area around the bilio- and pancreatico-enteric anastomoses.organization: University of Amsterdam
