A Resected Case of Simultaneous cholangiocarcinoma and Gastric Cancer

We experienced a rare case of cholangiocarcinoma combined simultaneously with gastric cancer. A 69-year-old male was admitted to our hospital because of dilated intrahepatic bile duct and mass in the lateral segment of the liver diagnosed on enhanced CT scan and ultrasound examination. Endoscopic retrograde changiography showed obstruction of the bile duct in the lateral segment of the liver. Angiography showed encasement of the left hepatic artery. Simultaneously endoscopic study of the upper gastrointestinal tract showed a Iia + IIc lesion at the antrum of the stomach. Therefore we preoperative diagnosed cholangiocarcinoma associated with gastric cancer. Distal partial gastrectomy, left hepatectomy and left caudate lobectomy with lymph node dissection were performed for these lesions. The patient was died of peritoneal carcinomatosis caused by advanced cholangiocarcinoma after surgery. We found only six case reports of cholangiocarcinoma combined simultaneously with gastric cancer in Japan. Because cholangiocarcinoma shows a poor prognosis, protection of peritoneal carcinomatosis and more extended radical resection would needed to improve its prognosis.
