[The current situation and treatment strategy for gastric cancer at the National Cancer Center of Tokyo, Japan].

At the National Cancer Center of Tokyo Gastric Division, from 13/09/1993 to 12/11/93, 42 gastrectomies, 3 local resections and 1 exploratory laparotomy, for gastric cancer, were carried out. Resection R2 were carried out in 29/42 (69%), resection R2 plus dissection of the station 16 in 5/42 (12%), resection R3 plus dissection of the station 16 in 4/42 (9.5%) and distal pancreas preserving in 11/14 (78.6%) of the total gastrectomies. The most frequently type of reconstruction done after distal gastrectomy was Billroth 1 in 20/28 (71.4%) and the most frequent stage of the disease was la-b in 34/46 (74%). Postoperative severe complications were present in 5/42 (12%) and the most frequently histological type was tubular adenocarcinoma 27/46 (58.7%).

Intrahepatic cholangiocarcinoma presenting intrabile duct tumor growth: report of a case.

A case of intrahepatic cholangiocarcinoma with intrabile duct tumor growth is presented. A 70-year-old female with prolonged obstructive jaundice and cholangitis was diagnosed with a mass lesion in the left lobe of the liver accompanied by an intrabile duct component which caused hilar bile duct obstruction. Percutaneous transhepatic biliary drainage (PTBD) was performed via three routes with intensive care of the drainage catheters over a 2-month period to alleviate jaundice and cholangitis. Extended left hepatic lobectomy with combined resection of extrahepatic bile duct and regional lymph nodes were carried out curatively. Macroscopically, a tumor formed a 8 x 6 cm mass with a scalloped margin in the left lobe and had an intraductal component with a round smooth surface protruding from the lumen of the left hepatic duct into the common bile duct. The histologic type of the tumor was well differentiated tubular adenocarcinoma. The intraluminal tumor grew expansively without invasion to the bile duct wall. The postoperative course was uneventful and the patient has remained in good health without recurrence for 1 year and 3 months since surgery. This case report discusses a rare extension pattern in ICC and the management of malignant hilar obstruction during radical surgery.

Partial hepatectomy for metastatic seeding complicating pancreatoduodenectomy.

We present a case report of metastatic seeding at the percutaneous transhepatic biliary drainage tract in a 68 year-old man who previously underwent pancreatoduodenectomy with bile duct resection for distal bile ductal carcinoma. Three years and 5 months after the initial operation, dilation of the left lateral segmental bile ducts was detected by abdominal ultrasonography. Percutaneous transhepatic cholangiography disclosed a stricture at the confluence of the ventral and dorsal branches of the left lateral anterior segmental duct. This region corresponded to the punctured point of the previous percutaneous transhepatic biliary drainage. Implantation of the bile duct carcinoma at the percutaneous transhepatic biliary drainage sinus tract was diagnosed, and the recurrent tumor was successfully resected by an extended left hepatic lobectomy with a total caudate lobectomy. Currently, 8 years and 3 months after the second surgery, the patient is in good health without any signs of tumor recurrence. This case report discusses the entity of metastatic seeding, a rare but serious complication of percutaneous transhepatic biliary drainage. An aggressive surgical approach is important for recurrent biliary tract malignancies.
