Hyperplasia of Brunner glands with a lesion greater than 1 cm was initially described as a Brunner gland adenoma. Several features of these lesions favor their designation as hamartomas, including the lack of encapsulation; the mixture of acini, smooth muscles, adipose tissue, Paneth cells, and mucosal glands; and the lack of any cell atypia ...
Duodenal lymphocytosis; Idiopathic; Types. Acute duodenitis; Chronic duodenitis; Diagnosis. Diagnosis is generally made by endoscopy with biopsy to evaluate histology ...
The definition of the condition includes the requirement that the duodenal histological appearances are otherwise unremarkable, specifically with normal villous architecture. [2] In coeliac disease (also known as gluten-sensitive enteropathy), duodenal lymphocytosis is found in untreated or partially treated cases. This is the least severe type ...
Secretin, which is a hormone released from the duodenal S cells that induces the release of pancreatic bicarbonate (HCO 3) that would neutralize the acidic environment due to high gastrin levels. Therefore, if the patient's level of gastrin remains consistently high indicating gastrin release due to tumor such as gastrinoma.
Duodenal-type follicular lymphoma (DFL) is a form of lymphoma in which certain lymphocyte types, the B-cell-derived centrocytes and centroblasts, form lymph node follicle-like structures principally in the duodenum and other parts of the small intestine. It is an indolent disease which on rare occasions progresses to a more aggressive lymphoma ...
In these cases, re-operation rates were 31% and 27%, respectively, indicating that strictureplasty is a safe and effective treatment for selected people with duodenal involvement. [228] Postsurgical recurrence of Crohn's disease is relatively common. Crohn's lesions are nearly always found at the site of the resected bowel.
Peptic ulcers are most commonly caused by a bacterial Helicobacter pylori infection. [5] Epstein–Barr virus infection is another factor to induce gastric cancer. [6] [7] As well as peptic ulcers, vomiting blood may result from abnormal arteries or veins that have ruptured, including Dieulafoy's lesion and Gastric antral vascular ectasia.
Truncal vagotomy is a treatment option for chronic duodenal ulcers. [5] [6] It was once considered the gold standard, but is now usually reserved for patients who have failed the first-line "triple therapy" against Helicobacter pylori infection: two antibiotics (clarithromycin and amoxicillin or metronidazole) and a proton pump inhibitor (e.g., omeprazole).
