Study Notes
Peptic Ulcers: Pathophysiology, Diagnosis, and Management
- Chronic use of NSAIDs suppresses mucosal prostaglandin synthesis, leading to decreased bicarbonate secretion, mucin production, and increased hydrochloric acid secretion, contributing to peptic ulcer pathogenesis.
- Zollinger-Ellison syndrome is a rare cause of peptic ulcers, associated with gastrin-secreting neuroendocrine tumors in the pancreas or duodenum, resulting in excess gastric acid secretion and ulcers.
- Diagnosis of Zollinger-Ellison syndrome involves secretin- or calcium-stimulated gastrin level measures, gastric pH levels, and symptomatic evidence of peptic ulcer disease.
- Proton pump inhibitors reduce gastric acid secretion, while surgical removal of tumors limits metastasis in Zollinger-Ellison syndrome.
- Duodenal ulcers are commonly caused by H. pylori infection and NSAID use, with rare idiopathic cases associated with altered mucosal defenses, rapid gastric emptying, elevated serum gastrin levels, or smoking-induced acid production.
- Acid and pepsin concentrations in the duodenum penetrate the mucosal barrier, leading to ulceration, often facilitating H. pylori infection.
- Clinical manifestations of duodenal ulcers include chronic intermittent epigastric pain, particularly after eating and relieved by food or antacids, with some individuals being asymptomatic.
- Diagnostic differentiation of duodenal ulcers from other conditions involves endoscopic evaluation, radioimmune assays of gastrin levels, and H. pylori detection using various tests.
- Management of duodenal ulcers aims to relieve hyperacidity, prevent complications, and eradicate H. pylori, utilizing antacids, acid secretion suppressants, antibiotics, probiotics, ulcer-coating agents, anticholinergic drugs, and diet therapy.
- Surgical resection may be necessary for duodenal ulcer complications such as bleeding, perforation, obstruction, or peritonitis.
- Gastric ulcers are less common than duodenal ulcers, usually occurring between the ages of 55 and 65 years.
- Gastric ulcers require similar diagnostic and management approaches as duodenal ulcers, including endoscopic evaluation, H. pylori detection, and a range of therapeutic interventions.
