Introduction Annular pancreas is a rare congenital abnormality characterized by a ring of pancreatic tissue surrounding the descending portion of the duodenum. Annular pancreas coexisting with replaced common hepatic artery which is also a rare anatomical variation has not been reported previously. Case Presentation A 53-year-old man visited our hospital complaining of epigastric pain. Based ...

Ectopia of the pancreatic tissue is a developmental anomaly found in ~2% of all autopsies, and 70~90% of these anomalies are located in the gastrointestinal tract. Mediastinal localization of an ectopic pancreas is extremely rare. Herein, we report two cases with mediastinal ectopic pancreas clarified by pathology and shown by thoracic contrast-enhanced computed tomography (CT) and magnetic res...

abstract background: the pancreatojejunostomy has notoriously been known to carry a high rate of operative complications, morbidity and mortality, mainly due to anastomotic leak and ensuing septic complications. objective: in order to decrease anastomotic leak and its attendant morbidity and mortality in operations requiring a pancreato-jejunal anastomosis, and also in order to simplify the ope...

CONTEXT Complete agenesis of the dorsal pancreas is an unusual congenital anomaly. Nowadays, the diagnosis is based on four imaging studies: transabdominal ultrasonography, computed tomography, magnetic resonance cholangiopancreatography and, the gold-standard, endoscopic retrograde cholangiopancreatography. Sometimes the ability of these studies are limited to distinguishing agenesis of the do...

Hyperspectral anomaly detection is one of the main challenging topics in both military and civilian fields. The spectral information contained in a hyperspectral cube provides a high ability for anomaly detection. In addition, the costly spatial information of adjacent pixels such as texture can also improve the discrimination between anomalous targets and background. Most studies miss the wort...

Situs inversus totalis (SIT) denotes complete right-left inversion of the thoracic and abdominal viscera. Diagnosis and surgical procedures for abdominal pathology in patients with SIT are technically more complicated because of mirror-image transposition of the visceral organs. Moreover, SIT is commonly associated with cardiovascular and hepatobiliary malformations, which make hepatobiliary-pa...

JF305 is a highly prolific pancreatic cancer cell line that originated from a Chinese patient. The cell line bears a functional HR double strand DNA repair mechanism but very responsive to PARP treatment a phenomenon clearly suggesting presence of an anomaly in the mechanism. Brca1, Brca2 and CHK2 proteins are very important constituents of the HR mechanism whose respective gene coding mutation...

A 74-year-old Japanese housewife was shown to have a large, smooth-surfaced, protruding, subpedunculated tumor covered with the normal-appearing mucosa on the posteromedial wall of the mid descending part of the duodenum immediately oral to the papilla of Vater by endoscopy. ERCP demonstrated the normal main and accessory pancreatic ducts. Just after abruptly contracted, the terminal common bil...

A 40-year-old female without history of alcohol consumption and medication suffered from persistent epigastralgia for four days and was admitted to our hospital. Elevated serum amylase and lipase levels were noted. She was admitted and treated under the working diagnosis of acute pancreatitis. Abdominal sonography showed normal common bile duct, but enlargement of the whole pancreas and mild ma...
