Article originalExérèses multiviscérales dans les polyposes familiales adénomateuses. À propos de neuf observationsMultivisceral resections of extracolorectal lesions in familial adenomatous polyposis

Aims. – 1/ To report our experience with multivisceral resections in familial adenomatous polyposis (FAP) for extracolorectal lesions in a cohort of nine patients. 2/ Discuss the long term results of an agressive surgery. Patients and methods. – Nine patients (7 males and 2 females) were operated at the University Hospital of Nimes (N = 4) and Nantes (N = 5). The median age at the first operation was 29 years (range 18–43). A genetic study was performed in six patients and confirmed the mutation on APC gene (exon 11, 13 and 15). All the patients were operated through a classic laparotomy. Results. – All patients have underwent a mean of three operations (range 2–5). Eight patients have had initially a total colectomy and 4 underwent subsequent proctectomy. Seven patients had pancreaticoduodenectomy for extensive duodenal adenomas and/or carcinoma. Three had one or multiple small bowel resections for development of carcinoma and one had partial gastric resection for large adenovillous tumor. The median follow up was 25 years (range 15–37) since the first operation. Three patients were died: one of gastric cancer with hepatic metastases, one of peritoneal carcinosis after ileal resection and one of astrocytoma. Conclusion. – With regard to these nine observations, the authors underline the possibility of multivisceral resection in FAP. Despite a major digestive mutilation, it permits a long survival with acceptable quality of life. The prognosis depends on the aggressiveness of the duodenal or jejunoileal lesions more than of the colorectal tumors if found at the first resection.
