Pyloric Obstruction

Pyloric obstruction is obstruction at gastric outlet (pylorus/antrum), due to peptic ulcer scarring, malignancy, adult hypertrophic pyloric stenosis, or inflammation, presenting with postprandial pain, vomiting of undigested food, weight loss, and dehydration. Treatment: NPO; nasogastric decompression; IV fluids/electrolytes (correct hypokalemic alkalosis); endoscopy to diagnose/treat (dilation for benign stricture, stent for malignancy); surgical resection/gastrojejunostomy; PPI for ulcer disease; nutritional support; treat underlying cause; follow-up to prevent recurrence.

Common Symptoms

Postprandial pain; vomiting of undigested food; weight loss/dehydration; by ulcer/malignancy/hypertrophy

Causes and Pathogenesis

Scarring/malignancy/hypertrophy causes gastric outlet obstruction.

Treatment

NPO; NG decompression; IV fluids; endoscopy; dilation/surgery; treat cause

Preventive Measures

Treat peptic ulcer early; surveillance endoscopy if at risk.
