Patients with postoperative intestinal obstruction can show the following symptoms: first, abdominal pain, which can appear as persistent abdominal distension and sometimes unbearable pain; second, the abdomen can be touched with intestinal pattern, and at the same time, the sound of air over water can be heard, and sometimes intestinal sounds cannot be heard when intestinal peristalsis is too poor; third, patients can also experience nausea, vomiting, abdominal distension, and difficulty in exhaustion and defecation. The treatment of intestinal obstruction can be divided into conservative treatment, medication, and also surgical treatment. If it is caused by poor exhaustion and defecation, enema treatment can be given, and saline or paraffin oil can be used as the enema solution. Some patients can also be treated with oral motivational drugs, such as Mosapride. If intestinal obstruction is considered to be caused by inflammatory infection, antibiotics may be given, but if conservative treatment does not work, another surgical exploration may be required to separate the adhesions or even remove the intestinal canal.
