Abdominal distension after ileostomy retrieval may be related to the stimulation of surgical operation, suppression of anesthetics, and fasting status. 1. Surgical operation: Ileostomy mainly involves direct anastomosis between the stoma end and the distal intestinal tube, which will stimulate and damage the blood vessels and intestinal nerves, etc. Even though the operation time is not long, the intestinal tube at the anastomosis will need a certain period of time to recover, and the intestinal peristalsis will be affected to a certain extent, so it is easy to be bloated after the operation. 2. Anesthesia drugs: Ileostomy requires general anesthesia, anesthesia drugs on the recovery of intestinal function there is a certain inhibitory effect, so postoperative intestinal peristalsis is easy to weaken abdominal distension, general anesthesia drug metabolism, intestinal peristalsis function recovery and exhaust, abdominal distension can be significantly relieved. 3. Fasting status: fasting is required in the early stage after ileostomy, so the lack of food stimulation of intestinal peristalsis reduces abdominal distension. In the later stage, with the gradual feeding, the vagus nerve excitation increases the secretion of digestive juices, which can promote the restoration of intestinal peristalsis, and the abdominal distension can be significantly relieved. If abdominal distension is severe after ileostomy, it is recommended that the patient communicate with the doctor in charge in a timely manner, so as to alleviate the discomfort and follow the doctor’s instructions.
