Five months after gastric surgery, the drain port did not heal, mostly considered due to the patient’s own poor nutritional status and incision infection, and may be the patient’s own existence of some special physical condition. For example, diabetes. For gastrointestinal surgery, usually the drain needs to be pulled out 3 to 5 days after the operation, long time to leave the drain tube is easy to cause infection, at the same time is not conducive to the healing of the wound, usually the wound can be initially healed within two weeks, after a month can be completely healed. If the wound is still not healed after surgery, the patient can eat more protein-rich food such as beef, fish, eggs, etc., considering that the patient’s own nutritional status is poor; there is also the possibility that the wound infection can lead to delayed healing of his own incision; as well as the patient’s own diabetic body caused by delayed healing of the wound.
