The small belly is distended and hard, generally speaking, the common reasons are mainly the following: a. Older patients have complete intestinal obstruction, mostly seen in a large amount of feces stagnation in the intestinal canal, causing significant expansion of the intestinal canal, and a hard intestinal shape can be palpated in the small abdomen during body check. Patients can take oral lactulose, pantopamine and low-pressure enema to promote the excretion of feces in the intestinal canal, so as to reduce the symptoms of distension and hardness in the small abdomen. Second, huge malignant tumor of uterus invades the lower abdomen, which can be accompanied by local intestinal tube compression, and the patient can touch a swollen and hard mass in the abdomen. Through CT examination, the size and source of the mass can be clarified, and surgery can be performed as soon as possible to remove the giant uterine tumor, so as to relieve the compression of intestinal canal in the abdomen and the symptoms of swelling and hardness.
