TREATMENT OF PEPTIC ULCER (PUD)

Treatment of peptic ulcers varies depending on the etiology and clinical presentation. The initial management of a stable patient with dyspepsia differs from the management of an unstable patient with upper GI hemorrhage. In the latter scenario, failure of medical management not uncommonly leads to surgical intervention.
Treatment options include empiric antisecretory therapy, empiric triple therapy for H pylori infection, endoscopy followed by appropriate therapy based on findings, and H pylori serology followed by triple therapy for patients who are infected. Breath testing for active H pylori infection may be used.
Endoscopy is required to document healing of gastric ulcers and to rule out gastric cancer. This usually is performed 6-8 weeks after the initial diagnosis of PUD. Documentation of H pylori cure with a noninvasive test, such as the urea breath test or fecal antigen test, is appropriate in patients with complicated ulcers.
Given the current understanding of the pathogenesis of PUD, most patients with PUD are treated successfully with cure of H pylori infection and/or avoidance of NSAIDs, along with the appropriate use of antisecretory therapy. Computer models have suggested that obtaining H pylori serology followed by triple therapy for patients who are infected is the most cost-effective approach; however, no direct evidence from clinical trials provides confirmation.
Perform endoscopy early in patients older than 45-50 years and in patients with associated so-called alarm symptoms, such as dysphagia, recurrent vomiting, weight loss, or bleeding. Age is an independent risk factor for the incidence and mortality from bleeding peptic ulcer, with the risk increasing in persons older than 65 years and increasing further in those older than age 75 years.[24] In one study, at least 2 risk factors (previous duodenal ulcer, H pylori infection, use of ASA/NSAID, and smoking) were present in two thirds of persons with acute gastroduodenal bleeding.[25]
The indications for urgent surgery include failure to achieve hemostasis endoscopically, recurrent bleeding despite endoscopic attempts at achieving hemostasis (many advocate surgery after 2 failed endoscopic attempts), and perforation. Many authorities recommend simple oversewing of the ulcer with treatment of the underlying H pylori infection or cessation of NSAIDs for bleeding PUD. Additional surgical options for refractory or complicated PUD include vagotomy and pyloroplasty, vagotomy and antrectomy with gastroduodenal reconstruction (Billroth I) or gastrojejunal reconstruction (Billroth II), or a highly selective vagotomy
