 · A duodenal ulcer is a circumscribed lesion in the mucosal membranes of the proximal part of the small intestines It follows a chronic course characterized by remission and exacerbation commonly requiring surgery Pathophysiology With a duodenal ulcer Helicobacter pylori releases a toxin that promotes mucosal inflammation and ulceration Ulceration stems from the inhibition of prostaglandin synthesis increased …

Pathogenesis and pathophysiology of duodenal ulcer

Helicobacter pylori infection down-regulates E-cadherin expression in gastric epithelial cells which affect the resistance of the mucosa to acid attack, Decreased mucus production, release of chemical mediators and down-regulation of E- cadherin leads to mucosal damage leads to ulcer formation,

 · Ulcer usually < 1 cm, circular, small, Brown ulcer base digested blood, no induration of margins of ulcer, Abrupt lesions with normal adjacent mucosa, No scarring or blood vessel thickening, Gastric foveolar cell metaplasia and chronic duodenitis common,

A The ulcer process starts with an imbalance between protective and hostile factors most frequently represented by Helicobacter infection for duodenal ulcers or the excessive use of nonsteroidal anti-inflammatory drugs for gastric ulcers Other modifiers include smoking drinking and several drugs

Duodenal Ulcer Nursing Case Studies with Pathophysiology

Much epidemiological clinical and pathophysiological evidence has accumulated to indicate that the aetiology of duodenal ulcer is heterogeneous Table 8 Recent advances in the medical therapy of duodenal ulcer support the long held concept that hyperacidity is an important physiological abnormality in the majority of patients with duodenal ulcer, It can also be shown that the origin of hyperacidity is heterogeneous, Certain …

Pathophysiology of duodenal and gastric ulcer and gastric

H pylori can elevate acid secretion in people who develop duodenal ulcers decrease acid through gastric atrophy in those who develop gastric ulcers or cancer and leave acid secretion largely unchanged in those who do not develop these diseases Several specialised cells in the gastric mucosa contribute to the control of acid secretion, G cells in the gastric antrum release the hormone gastrin, Gastrin acts on the enterochromaffin …
