Patients with combined colonic stenosis can be treated clinically according to the severity of the stenosis and whether it is accompanied by obvious obstructive symptoms: a. If the stenosis is mild and does not cause intestinal obstruction, and the intestinal contents can pass normally, it is recommended that patients choose conservative treatment methods, which can be done by eating liquid, easily digestible food to soften the stool and keep the stool open, so as to avoid progressive aggravation. Second, if the patient’s colon stenosis causes difficulty in passing intestinal contents, accompanied by different degrees of abdominal pain, abdominal distension and other manifestations of incomplete intestinal obstruction, it is necessary to implant an intestinal stent to expand the narrowed intestinal tube, which can often achieve certain therapeutic effects. Third, if the intestinal lumen is completely obstructed due to colonic stenosis, and the intestinal contents cannot pass completely, patients need to undergo surgery to remove the diseased intestinal tube, and release the symptoms of colonic stenosis by proximal and distal intestinal tube anastomosis or proximal intestinal tube fistula.
