Abstract
Pyloric duodenal stenosis is usually caused by pyloric, juxtapyloric or duodenal ulcer, or by postbulbar ulcer. Gallbladder cancer (GBC), duodenal diverticula, annular pancreas and superior mesenteric artery syndrome (Wilkie's syndrome) are rare causes of pyloric duodenal stenosis. The case of a 66-year-old female patient is presented. The patient was admitted to hospital presenting anorexia, repeated alimentary vomiting, epigastric pain, and weight loss. Objective clinical examination upon admission: clapotage à jeun is present, triggered by tapping the epigastric region. Laboratory tests reveal moderate anemia, hypokalemic alkalosis, increased levels of cholestatic enzymes and of tumor markers. Gastroendoscopy: Stomach presenting stasis fluid in large quantity. Deformed antropyloric region caused by extrinsic compression. Abdominal native magnetic resonance imaging (MRI) and with contrast medium: cholecyst lumen entirely obstructed with calculi; thickened wall, with heterogeneous gadolinophilia; gadolinophilic mass erasing the bordering limit in relation to the cholecyst wall and the colon hepatic angle, and leaving a print on the pyloric region. During surgery, upon opening the peritoneal cavity, a tumoral pericholecystic block was observed, including the pyloric-duodenal region and the transverse mesocolon. Histopathology tests of tissue samples showed adipose conjunctive tissue with invasive adenocarcinoma. Immunohistochemical tests [cytokeratin (CK) 7, CK17, CK19, CK20, CDX2, mucin (MUC) 1, MUC2, MUC5AC, MUC6, epithelial membrane antigen (EMA) and carcinoembryonic antigen (CEA)] were consistent with infiltrating neoplastic carcinoma, originating in the gallbladder epithelium. Gastrointestinal obstruction cases caused by gallbladder carcinoma are rare. The pyloric-duodenal region is more frequently affected, as compared to the small intestine or the colon.
