[A Case of Double Cancers of the Gallbladder and Duodenal Papilla]

A 65-year-old man was diagnosed with gallbladder cancer during a medical checkup that revealed liver dysfunction. He was referred to our hospital seeking bloodless treatment due to religious beliefs. Blood tests revealed elevated hepatobiliary enzyme levels, and abdominal echocardiography revealed a broad nodular protuberant lesion in the body of the gallbladder and marked dilatation of the common bile duct. PET revealed marked abnormal accumulation of FDG in the gallbladder mass and duodenal papilla. Based on the imaging findings, double cancers of the gallbladder and duodenal papilla were diagnosed. A subtotal gastric-sparing pancreaticoduodenectomy was performed along with resection of the liver bed, gallbladder, and bile ducts, and D2 regional lymph node dissection. Both of postoperative histopathologic diagnosis were papillotubular adenocarcinoma. The patient has remained recurrence-free for 5 years postoperatively. Double cancers of the gallbladder and duodenal papilla are rare, and we report this case based on a review of the literature.
