Gastric perforation is a common complication of gastric ulcer, with acute onset, rapid changes and severe condition. Gastric perforation suture or gastric resection is often used according to the degree of severity of the condition, and the surgical steps are roughly as follows: firstly, search for the site of the perforation after opening the abdomen, then choose different surgical methods according to the size of the perforation and the contamination of the abdominal cavity, and then close the abdominal cavity after treating the perforation and suture the incision. 1. Perforation closure: Laparoscopic perforation closure is preferred for patients with mild symptoms. Usually, the perforation is closed with a full layer of suture first, and then the free part of the greater omentum is covered over the repair site to reduce the chance of fluid leakage from the perforation. 2. Gastric resection: for patients with bleeding or serious contamination of the abdominal cavity, or for patients with gastric perforation, hemorrhage, pyloric obstruction, and carcinoma complicated by ineffective conservative treatment of gastric ulcer. The surgical procedure consists of resection of gastric tissue and reconstruction of the digestive tract. Gastrectomy usually involves removal of the distal 2/3 to 3/4 of the gastric tissue and the pylorus, and part of the duodenal bulb. There are various surgical methods for digestive tract reconstruction, and the specific surgical methods need to be considered in the light of the patient’s condition. Specific surgical methods and corresponding steps need to refer to the patient’s condition and his/her own situation, and it is recommended to make an individualized plan under the guidance of a professional physician in order to expect to reap the best therapeutic results.
