BACKGROUND/AIMS Duodenitis is not infrequent finding in patient undergoing endoscopy. However, hospitalized patients have a higher incidence of secondary duodenal mucosal lesions that might be related with inflammatory bowel disease (IBD), cytomegalovirus (CMV) infection, tuberculosis, immunologic disorders, or other rare infections. We aimed to identify clinicopathologic features of duodenal m...
We have reported that a single injection of 1 alpha,25-dihydroxyvitamin D3 (1 alpha,25(OH)2D3), the active form of vitamin D3, into vitamin D-deficient chicks produces a marked increase in the formation of duodenal putrescine by two pathways, one from ornithine and one from spermidine (Shinki, T., Takahashi, N., Kadofuku, T., Sato, T., and Suda, T. (1985) J. Biol. Chem. 260, 2185-2190). In this...
Duodenal injury following blunt abdominal trauma is uncommon. The severity of injury can vary from an intramural haematoma to a duodenal rupture with associated transection of the pancreatic duct. A case of duodenal rupture with avulsion of the ampulla of Vater is presented and discussed.
Duodenal varices are uncommon causes of gastrointestinal bleeding. In the literature, treatment of duodenal variceal bleeding is limited to case reports and case series. Treatment options are endoscopic, interventional radiologic and surgical modalities. In this article, we presented a case of a successful duodenal variceal bleeding treatment with transjugular intrahepatic portosystemic shunt. ...
2.6% of pancreatic cancer patients have the primary manifestation of gastrointestinal bleeding. It is not feasible to stop the duodenal hemorrhage caused by the pancreatic cancer infiltration. A 43-year-old woman who was diagnosed as having pancreatic cancer with multiple hepatic metastases and duodenal infiltration was administered gemcitabine and S-1 combination therapy. During the chemothera...
We report a case of lipoma in the antum of the stomach which prolapsed into the duodenal bulb and caused a duodenal ulcer, speculated to have been induced by the friction of its top against the duodenal mucosa. Although the ulcer healed after the administration of a proton pump inhibitor, the symptom of epigastric discomfort continued, suggested to be due to prolapsing. Therefore, a laparoscopi...
In 66 endoscopic duodenal biopsies studied retrospectively and in 84 paired duodenal and antral biopsies assessed prospectively campylobacter like organisms were seen in 22 (33%) of the retrospectively examined duodenal biopsies and in 61 (73%) examined prospectively, and in 70 (83%) of antral biopsies. In the duodenum the organisms were mostly confined to the surface epithelium in areas showin...
CONTEXT Benign proliferative changes of the Brunner's glands account for about 10% of neoplasias of the duodenal bulb. CASE REPORT The authors present a case of giant hamartoma of Brunner's glands. The patient presented clinically with vague epigastric discomfort. A pancreas-sparing duodenal resection was performed. The patient made an uneventful recovery and is well at a one year follow-up. ...
Somatostatin-producing neuroendocrine tumors (SOM-NETs) of the duodenum and pancreas appear to be heterogeneous. To determine their clinicopathological profiles, respective data were analyzed on a series of 82 duodenal and 541 pancreatic NETs. In addition, the clinical records of 821 patients with duodenal or pancreatic NETs were reviewed for evidence of a somatostatinoma syndrome. Predominant ...
Epidermal growth factor (EGF) is localised in man to salivary and Brunner's glands. It is present in large concentrations in saliva and duodenal contents but the mechanisms of its release have been little studied. This study carried out on four groups of healthy subjects was designed to determine the distribution and the release of immunoreactive EGF (IR-EGF) in salivary, gastric, duodenal, and...
