Background Patients with altered anatomy due to Roux-en-Y gastric bypass (RYGB) present unique diagnostic and therapeutic challenges when they present with periampullary pathology. We describe a series of patients who underwent pancreatoduodenectomy (PD) after gastric surgery with Roux-en-Y reconstruction and review the literature to highlight technical considerations and outcomes. Methods Patients from two institutions were identified and data regarding preoperative workup, operative conduct, and pathologic and clinical outcomes were collected. Results Eleven patients were included in the institutional series. At the time of periampullary pathology, the median age was 64 years and time since RYGB was 10 years. Median operative time was 361 minutes, estimated blood loss was 500 mLs, and length of stay was 6 days. Remnant gastrectomy was performed in nine patients and reconstruction was performed using the biliopancreatic limb (BP) without revision of the jejuno-jejunostomy in ten patients. Pathology revealed pancreatic cancer (8), chronic pancreatitis (2), and duodenal cancer (1). Three patients experienced major complications and there were no 90-day mortalities. Conclusion Pancreatic surgeons will see an increasing number of patients with Roux-en-Y anatomy who will require evaluation and resection for periampullary diseases. For PD after RYGB, we recommend remnant gastrectomy with reconstruction using the BP limb.
