Obstruction of the passage of gastrointestinal contents due to various reasons is called intestinal obstruction, and patients with intestinal obstruction can develop acid-base balance disorders, which need to be dealt with promptly. Surgery is an important measure in the treatment of intestinal obstruction. For patients with postoperative intestinal obstruction, they can eat canned fruits if the surgery goes well, there are no corresponding postoperative complications, and the function of the gastrointestinal tract is completely restored after a few days. Dietary precautions after surgery are often related to the patient’s specific condition and need to be implemented in accordance with the doctor’s instructions, and if in doubt, communicate with the doctor in charge and follow the instructions. Surgical methods for intestinal obstruction include simple intestinal obstruction relief surgery, intestinal resection and intestinal anastomosis, intestinal short-circuit anastomosis, intestinal stoma or intestinal tube externalization surgery, etc., which are chosen according to different conditions.
