Gastrojejunostomy is a surgical procedure that creates a bypass between the stomach and the jejunum, part of the small intestine. This surgery is typically performed in cases where there is a blockage or narrowing in the stomach or duodenum that prevents food from passing through.

The procedure involves rerouting food around the obstruction by connecting the stomach directly to the jejunum. It is commonly used in the treatment of gastric cancer, peptic ulcers, or gastric outlet obstruction.

Postoperative care includes managing pain, supporting digestion with a modified diet, and monitoring for complications like infection or leakage from the surgical site. Nutritional supplements may be needed to address any absorption issues.

Gastrojejunostomy provides an effective solution for patients with gastric obstructions, improving digestion and quality of life by allowing normal food passage through the intestines.
