Summary
This document provides a detailed overview of peptic ulcer disease, including its surgical aspects, epidemiology, and pathology. It covers topics such as the definition of ulcers versus erosions, the incidence of gastric and duodenal ulcers, and cause and pathophysiology including the balance between mucosal protectors and aggressors. The lecture also discusses treatment options, both pharmacological and surgical.
