| duodenal glands | Small, branched, coiled tubular glands that occur mostly in the submucosa of the first third of the duodenum; they secrete an alkaline mucoid substance that serves to neutralise gastric juice. Synonym: glandulae duodenales, Brunner's glands, Wepfer's glands. (05 Mar 2000) |

| duodenal impression | A hollow on the visceral surface of the right lobe of the liver alongside the gallbladder, marking the situation of the duodenum. Synonym: impressio duodenalis. (05 Mar 2000) |

| duodenal smear | A group of cytologic specimens containing material from the mouth (oral smear), oesophagus and stomach (gastric smear), duodenum (paraduodenal smear), and colon, obtained by specialised lavage techniques; used principally for the diagnosis of cancer of those areas. (05 Mar 2000) |
| duodenal sphincter | One of the physiological sphincter's described in the duodenum. (05 Mar 2000) |
| duodenal tumours | <radiology> 90% benign, in 2nd and 3rd portion: 50% malignant, in 4th portion: most malignant, of malignancies: 80-90% leading to adenocarcinoma Differential diagnosis: benign, tubular adenoma, leiomyoma, lipoma, hamartoma (Peutz-Jeghers), prolapsed antral polyp, Brunner's gland adenoma (really hypertrophy and hyperplasia), malignant, adenocarcinoma (80-90% of malignant lesions), villous adenoma (pre-malignant), carcinoid / isleT-cell tumour (12 Dec 1998) |
| duodenal ulcer | A nonmalignant ulcer that develops in the portion of the gastrointestinal tract that is exposed to gastric secretions. Peptic ulcers occur in the stomach or duodenum. Common symptoms include epigastric abdominal pain and anorexia. Complications include perforation, penetration (into adjacent organs) and bleeding. The microorganism Helicobacter pylori has been implicated in the development of peptic ulcer disease. For this reason, new therapies may now involve the use of oral antibiotics. (27 Sep 1997) |
| inferior duodenal fold | A fold of peritoneum bounding the inferior duodenal recess. Synonym: plica duodenalis inferior, plica duodenomesocolica, duodenomesocolic fold. (05 Mar 2000) |
| inferior duodenal fossa | The variable peritoneal recess which lies behind the inferior duodenal fold and along the ascending part of the duodenum. Synonym: recessus duodenalis inferior, Gruber-Landzert fossa, inferior duodenal fossa. (05 Mar 2000) |
| inferior duodenal recess | The variable peritoneal recess which lies behind the inferior duodenal fold and along the ascending part of the duodenum. Synonym: recessus duodenalis inferior, Gruber-Landzert fossa, inferior duodenal fossa. (05 Mar 2000) |
| thickened duodenal folds | <radiology> Inflammatory, peptic ulcer (most common cause), Zollinger-Ellison syndrome, pancreatitis, cholecystitis, Crohn disease, infection (TB, parasites, cryptosporidia in AIDS), neoplastic, lymphoma, infiltrative, Whipple disease, amyloidosis, eosinophilic enteritis, vascular, intramural haematoma, ischemia, oedema, hypoproteinaemia, portal hypertension, congestive heart failure (12 Dec 1998) |
| ulcer, duodenal | An ulcer (a hole in the lining) of the duodenum (the first portion of the small intestine). Ulcer formation is related to h. Pyloridus bacteria in the stomach, anti-inflammatory medications, and smoking cigarettes. Ulcer pain may not correlate with the presence or severity of ulceration. Diagnosis is made with barium X-ray or endoscopy. Complications of ulcers include bleeding and perforation. Treatment involves antibiotics to eradicate h. Pyloridus, eliminating risk factors, and preventing complications. (12 Dec 1998) |
