Bowel obstruction after gastric cancer resection can be divided into two cases: one is bowel obstruction caused by intestinal adhesion after surgery, and usually the degree of patients’ disease varies, if the obstruction is mild, it can be relieved by reducing food intake or fasting and water. If the obstruction is mild, it can be relieved by reducing food intake or fasting with water. If the obstruction is moderate, it requires fasting, water and parenteral nutritional support to maintain the balance of water and electrolytes, and acid-suppressing and anti-infective treatments can often lead to recovery. If severe intestinal obstruction is ineffective in conservative treatment, surgery is needed. Another situation is that the intestinal obstruction is caused by the recurrence of gastric cancer, at this time, it is necessary to further evaluate whether it is possible to perform surgery again to remove the lesion, and the specific situation needs to be determined according to the patient’s specific condition.
