There is really no good way to deal with abdominal distension when stomach cancer patients have poor gastrointestinal digestive function, but they can take oral medicine to promote gastrointestinal peristalsis and help digestion, such as mosapride, morpholine, compound digestive enzyme, etc., which may have many definite effects. If hypoproteinemia or cancer metastasis causes large amount of ascites causing abdominal distension, laparotomy can be done to drain ascites from the tube to temporarily relieve the symptoms of abdominal distension, and at the same time, albumin can be supplemented and excessive water can be eliminated from the body through urine with diuretic treatment. If the patient can tolerate chemotherapy, he can be given effective systemic combination chemotherapy. If he cannot tolerate chemotherapy, he can also undergo intraperitoneal infusion chemotherapy, which means that chemotherapy drugs can be injected directly into the abdominal cavity to temporarily relieve the symptoms of abdominal distension.
