Gastric stump carcinoma as a long-term complication of pancreaticoduodenectomy: report of two cases and review of the English literature

چکیده
BACKGROUND Gastric stump carcinoma is an exceptional and poorly known long-term complication after pancreaticoduodenectomy. CASES PRESENTATION Two patients developed gastric stump carcinoma 19 and 10 years after pancreaticoduodenectomy for malignant ampulloma and total pancreaticoduodenectomy for pancreatic adenocarcinoma, respectively. Both patients had pT4 signet-ring cell carcinoma involving the gastrojejunostomy site that was revealed by bleeding or obstruction. Patient 1 is alive and remains disease-free 36 months after completion gastrectomy. Patient 2 presented with peritoneal carcinomatosis and died after palliative surgery. We identified only 3 others cases in the English literature. CONCLUSIONS Prolonged biliary reflux might be the most important risk factor of gastric stump carcinoma following pancreaticoduodenectomy. Its incidence might increase in the future due to prolonged survival observed after pancreaticoduodenectomy for benign and premalignant lesions.
