For symptoms of intestinal obstruction, the typical manifestations are abdominal pain, bloating, vomiting, and cessation of passing gas or stool. Most people may experience several of these symptoms; however, the severity of the symptoms depends on the location and condition of the obstruction. Once symptoms of intestinal obstruction occur, it is necessary to refrain from eating and then carry out appropriate examinations. Identifying the cause of the obstruction is crucial. If the obstruction is caused by tumor-related factors, surgical treatment should be considered based on a comprehensive assessment. If the obstruction is due to adhesions, conservative treatment methods should be adopted where possible.
