In pancreatoduodenectomy (PD), mesopancreas excision with division of the inferior pancreatoduodenal artery (IPDA) is technically difficult because of the complex anatomy resulting from intestinal rotation occurring during embryological development. We have developed an intestinal derotation procedure for facilitating mesopancreas excision. The perioperative factors of PD were retrospectively compared...
Background: The aim of this study was to establish an optimal management strategy for pancreatic disorders associated with anomalous pancreaticobiliary junction (APBJ). Methods: In 64 adult surgical cases of APBJ (common channel 15 mm or longer) (43 with and 21 without choledochal cyst), associated pancreatic disorders, pancreatographic results, and treatment outcomes were analyzed. Results: Of 64...
Background: Conventional preoperative imaging modalities are unreliable for assessing portal venous invasion by pancreatobiliary carcinoma. We evaluated the usefulness of intraoperative ultrasonography for detecting pancreatobiliary carcinoma and assessing portal venous invasion, compared with other imaging modalities. Methods: Ninety-one patients with pancreatic carcinoma (n = 66) or bile duct carcinoma...
Background: Acute biliary pancreatitis, particularly severe pancreatitis, necessitates urgent diagnosis and treatment of common bile duct (CBD) stones. The roles of urgent endoscopic ultrasonography (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) in the management of biliary pancreatitis were prospectively studied. Methods: Thirty-five consecutive patients with suspected acute biliary...
Background: Anomalous pancreaticobiliary junction (a long common channel), with or without congenital choledochal cyst, is frequently associated with biliary tract carcinoma. We assessed the diagnostic value of magnetic resonance cholangiopancreatography (MRCP) for patients with anomalous pancreaticobiliary junction (PBJ). Methods: In 159 adult patients with pancreatobiliary disease, breath-hold (1...
Background. This study focuses on clinicopathologic, imaging, and prognostic differences between two types of mucin-producing cystic tumors of the pancreas, with the aim of appropriate management of these tumors.Methods. Forty-six patients with mucin-producing cystic tumors underwent operation. The types of tumors were as follows: mucinous cystic neoplasm, adenoma (6) and adenocarcinoma (12); intraductal...
