Study design: Case Report
Abstract: INTRODUCTION: Portal annular pancreas (PAP) is a rare congenital anomaly in which the uncinate process encircles the portal vein (PV) or superior mesenteric vein (SMV) and fuses with the dorsal aspect of the pancreatic body. We herein report a case of ampullary carcinoma associated with PAP treated by subtotal stomach-preserving pancreaticoduodenectomy. CASE PRESENTATION: A 51-year-old woman presented with scleral icterus and watery diarrhea. Following a detailed examination, she was diagnosed with carcinoma of the ampulla of Vater and underwent surgical treatment. During pancreatic resection, 2 pancreatic cut surfaces were identified on the ventral and dorsal sides of the SMV, leading to the intraoperative diagnosis of PAP. A lifted jejunal limb was rotated in a spiral fashion, and pancreaticojejunostomy was performed for each pancreatic stump. The postoperative course was uneventful, with no evidence of postoperative pancreatic fistula, and the patient was discharged in good condition. CONCLUSIONS: Although PAP is a rare anatomical anomaly, it requires careful attention during surgical procedures and reconstruction; therefore, it should be recognized preoperatively whenever possible. The reconstruction method employed in the present case may be useful as a reconstructive option for PAP because it avoids excessive pancreatic resection. We report this case with a review of the relevant literature.
