Aim:
To investigate the role of ischemia in the pathogenesis of small bowel strictures.
Methods:
Vascular anatomy of 39 small bowel strictures was studied using modified Spalteholtz method. Ten normal small bowel segments were studied as controls.
Results:
71.8% of small bowel strictures showed block in the mesenteric vessels (p=0.008). Subset analysis of tuberculous strictures showed block in the mesenteric vessels in 70.8% of strictures (p=0.0098).
Conclusions:
Ischemia plays a significant role in the pathogenesis of small bowel strictures. Mesenteric vasculopathy has a significant association with tuberculous strictures of the intestine.

Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
Histology of the Small Intestine
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
Histology of the Large Intestine
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...
