Cystic artery and cystic duct assessment with 64-detector row CT before laparoscopic cholecystectomy.

Purpose: To retrospectively assess 64-detector row computed tomography (CT) in the preoperative depiction of the cystic duct and cystic arteries in and around the Calot triangle.

Materials And Methods: Institutional review board approval was obtained, with waiver of informed consent. A total of 245 consecutive patients (133 men, 112 women), including 48 patients who subsequently underwent cholecystectomy, were examined.

Histological study of gallbladder and bile duct epithelia in patients with anomalous arrangement of the pancreaticobiliary ductal system: comparison between those with and without a dilated common bile duct.

Background: We histologically evaluated the epithelia of the gallbladder (GB) and bile duct (BD) in patients with anomalous arrangement of the pancreaticobiliary ductal system (AAPB), with regard to the shape of the common BD (CBD).

Methods: The GB and BD were studied histologically using surgical materials from 44 patients with AAPB: 27 with a dilated CBD (D-type) and 17 with a nondilated CBD (N-type).

Results: GB cancer and BD cancer were found in 11.

[A case of superficial bile duct carcinoma showing extensive intraductal spread without bile duct stenosis, diagnosed by intraductal ultrasonography].

We report a case of superficial bile duct carcinoma showing extensive intraductal spread without dilatation of the bile duct in which diagnosis was established preoperatively by transpapillary forceps biopsy and intraductal ultrasonography. A 78-year-old man was given a diagnosis of acute cholecystitis, and percutaneous transhepatic gallbladder drainage (PTGBD) was performed. Cholangiography via the PTGBD tube revealed a tiny irregularity in the hilar bile duct.

Mode of progression of intraductal papillary-mucinous tumor of the pancreas: analysis of patients with follow-up by EUS.

Background: We investigated the mode of progression of intraductal papillary-mucinous neoplasm of the pancreas (IPMN) in patients who underwent follow-up in order to elucidate the characteristics of malignancy and to establish an effective treatment strategy.

Methods: Fifty-one patients with IPMN (branch-duct type, 47; main-duct type, 4) who had undergone follow-up study by endoscopic ultrasonography (EUS) were included (mean follow-up duration, 41.0+/-32.

Serous cystadenoma of the pancreas associated with obstructive jaundice.

We herein report a case of pancreatic serous cystadenoma in a patient who presented with jaundice, and we provide a review of the literature. A 53-year-old man was admitted with complaints of jaundice and weight loss. With a preoperative diagnosis of pancreatic serous cystadenoma with obstructive jaundice, he underwent pylorus-preserving pancreatoduodenectomy.
