Most of the gastric tube can be taken out in 3~7 days after gastric perforation surgery, the details of which are closely related to the surgical condition and postoperative recovery. If the gastric perforation is simply repaired, the gastric tube can be taken out in about 3 days as long as there is normal gas and defecation; if the anastomosis is done after the gastric resection, the recovery time will be longer, and it will take 5~7 days. Better health, good postoperative recovery status, and generally faster recovery of gastrointestinal function, can be relatively early gastric tube removal, need to be operated under the clinician. After the gastric perforation operation, we should pay attention to closely observe the recovery of the operation area and the status of defecation, once obvious gastrointestinal reaction or persistent non-defecation, we need to consult a doctor for observation and standardized treatment under the guidance of the clinician in order to avoid delaying the condition.
