Rectal cancer is a malignant tumor that occurs in the rectum. Because the rectum is an organ for storing stool, once a tumor occurs in the rectum, it can easily cause luminal narrowing, which can lead to stool obstruction. Once stool obstruction and intestinal obstruction occurs, it may be life-threatening, so an emergency, temporary fistula is needed to allow stool to pass out from the intestine to relieve the occurrence of intestinal obstruction. Therefore, a temporary stoma in the abdominal wall is needed to facilitate the passage of stool when rectal cancer patients experience intestinal obstruction. When the rectal cancer is removed by radical surgery, the stoma can be returned if the disease is stable, thus improving the patient’s quality of life. Of course, if the rectal cancer is not resected by radical surgery, the temporary stoma will be preserved permanently.
