## Overview Duodenal stricture is narrowing of the duodenum, most often from scarring after ulceration (especially in foals) or from other inflammatory or neoplastic processes. It obstructs outflow from the stomach, producing recurrent colic after feeding, gastric reflux, and weight loss. ## Causes Healed duodenal ulcers, chronic inflammation, or rarely neoplasia or external compression. ## Diagnosis History of postprandial colic and reflux, plus contrast radiographs, ultrasound, or endoscopy/gastroscopy demonstrating delayed gastric emptying and narrowing. ## Treatment Surgical bypass (gastrojejunostomy) is often required for significant strictures. Medical management of concurrent ulcers is supportive. ## Recovery and Prognosis Guarded. Surgical cases can do well if performed before severe debilitation, but complications occur. ## Prevention Prompt treatment of duodenal ulceration in foals may reduce stricture formation.
