BACKGROUND/PURPOSE The results from the Japanese Biliary Tract Cancer Statistics Registry from 1988 to 1998 were reported in 2002. In the present study, we report here selectively summarized data as an overview of the 2006 follow-up survey of the registered cases from 1998 to 2004 for information bearing on problems with the treatment of cancer of the(More)
It is widely accepted that congenital choledochal cyst is associated with pancreaticobiliary maljunction (PBM). But, PBM is an independent disease entity from choledochal cyst. PBM is synonymous with “abnormal junction of the pancreaticobiliary ductal system”, “anomalous arrangement of pancreaticobiliary ducts”, “anomalous union of bilio-pancreatic ducts”,(More)
INTRODUCTION Pancreaticobiliary maljunction (PBM) is a congenital anomaly, which can be defined as a union of the pancreatic and biliary ducts located outside off the duodenal wall. We herein investigate clinical features of PBM including as the 2nd report of a Japanese nationwide survey. PATIENTS AND METHODS During a period of 18 years (from 1990 to(More)
BACKGROUND/PURPOSE It is important to predict the development of clinically relevant pancreatic fistula (grade B/C) in the early period after pancreaticoduodenectomy (PD). This study has been carried out as a project study of the Japanese Society of Hepato-Biliary-Pancreatic Surgery (JSHPBS) to evaluate the predictive factors associated with clinically(More)
BACKGROUND/AIMS Intraductal papillary mucinous neoplasm (IPMN) and pancreatic endocrine tumors can develop at multiple sites of the pancreas at the same time, sometimes necessitating total pancreatectomy. When low-grade pancreatic malignancy is treated surgically, preservation of function to improve long-term QOL is emphasized. For low grade malignancy(More)
BACKGROUND/AIMS Although the role of hepatectomy for patients with colorectal liver metastases is well established, few reports exist of hepatectomy for patients with metastases of gastric cancer origin. This study reviews cases of hepatectomy for metastatic gastric cancer at Fujita Health University Hospital. METHODOLOGY Between 1989 and 2004, 18(More)
We posed six clinical questions (CQ) on preoperative biliary drainage and organized all pertinent evidence regarding these questions. CQ 1. Is preoperative biliary drainage necessary for patients with jaundice? The indications for preoperative drainage for jaundiced patients are changing greatly. Many reports state that, excluding conditions such as(More)
The 3(rd) English edition of the Japanese classification of biliary tract cancers was released approximately 10 years after the 5(th) Japanese edition and the 2(nd) English edition. Since the first Japanese edition was published in 1981, the Japanese classification has been in extensive use, particularly among Japanese surgeons and pathologists, because the(More)
The tumor production of human calcitonin (CT) was examined by radioimmunoassay, and it was found that 50 of 85 (59%) tumor tissues collected at random contained immunoreactive CT. These tumors were grouped as to whether they were derived from the amine precursor uptake and decarboxylation (APUD) series. The group that was derived from APUD cells showed(More)
Duodenum-preserving pancreatic head resection with preservation of the bile duct or without, has been performed in cases of benign or low-grade malignancies, such as intraductal papillary tumors, of the head of the pancreas. However, the selection of the patients, the area of resection in the head of the pancreas, and the operative procedures for the(More)
