The common surgical procedures for pyloric obstruction are usually distal gastrectomy and gastrojejunostomy. 1. Most of the gastrectomy is to remove the distal 2/3 to 1/2 of the gastric body, including the entire sinus, pylorus and duodenal bulb, and anastomose the remnant stomach directly to the duodenum. This procedure is more effective in treating gastric ulcer and is suitable for young people. 2. Gastrojejunostomy is to anastomose the lower part of the stomach directly to the small intestine. It is suitable for patients with unresectable gastric pyloric tumor and pyloric obstruction who cannot tolerate gastrectomy. This procedure is easy to perform, takes less time, and is suitable for the elderly and people with multiple underlying diseases. The above options are for reference only, and specific surgical methods should be selected under the guidance of a professional doctor.
