Laparoscopic gastric perforation repair is one of the most commonly used minimally invasive surgical approaches in clinical practice. The general specific steps are as follows: I. The patient is placed in a flat position, and after satisfactory general anesthesia, the perforation hole of the abdominal cavity is established at the navel, two centimeters from the lower edge of the left rib arch, and three centimeters from the lower edge of the right rib arch, respectively, and an artificial pneumoperitoneum is established. Second, the degree of infection in the abdominal cavity was explored to find the specific site of gastric perforation, and the fluid and pus accumulation in the abdominal cavity was removed by suction to reduce further absorption of toxins. Third, after clarifying the site of perforation, absorbable sutures are generally used to close the gastric perforation by performing a figure-of-eight suture at the perforation to avoid continuous leakage of gastric juice into the abdominal cavity. At the same time, the large omentum is covered over the perforated area to avoid recurrence of perforation. Fourth, the abdominal cavity was thoroughly cleaned of purulent secretions, and abdominal drains were placed in the gastric perforation site and pelvis respectively to adequately drain the cavity and end the operation.
