Abstract

Background: Pancreaticoduodenectomy is often required in patients with duodenal adenoma and adenocarcinoma and these patients generally have soft pancreatic texture and small pancreatic ducts, the two most significant factors associated with post-operative pancreatic fistula (POPF). The aims of the study were to evaluate the rate of POPF and long-term outcomes for patients with duodenal adenoma and adenocarcinoma who underwent curative resection. Methods: This retrospective study (2004–2014) examined patients treated surgically with non-ampullary duodenal tumours (NADTs) in two hepatopancreaticobiliary units in Victoria, Australia, and Swansea, UK. Results: There were 49 resections performed including 33 pancreaticoduodenectomies, five pancreas-preserving total duodenectomies and 11 segmental duodenal resections. Median length of follow-up was 23.5 months. Final histopathology revealed 18 duodenal adenomas and 31 adenocarcinomas. POPF rate for NADTs was 28.9% (of which 54.5% were grade C) compared to 14.5% for all other pathologies. Grade C POPF was associated with poorer survival outcomes (hazard ratio = 6.73; P = 0.005). The 5-year overall survival for patients with duodenal adenocarcinoma was 66.5%. Conclusion: Due to the soft pancreatic texture and small pancreatic duct, pancreatic resection for NADTs is associated with a high rate of POPF which contributes to reduced survival. Nevertheless, surgery is associated with favourable 5-year survival compared to pancreatic resection for pancreatic adenocarcinoma.
