Other Treatment
Draining an abscess. In some cases of diverticulitis, a pocket of infection (abscess) in the abdomen heals on its own. At other times it can be drained without surgery. A needle is passed through the skin into the abscess, and the liquid containing the infection is drained. A computed tomography (CT) scan is used to help the doctor guide the needle into the abscess. Sometimes a plastic drain is placed temporarily in the abdomen to drain the abscess.
Bowel rest. A blocked colon can sometimes be treated with bowel rest. You are not given anything to eat but instead receive fluids and nutrients through a tube connected to a vein. Suction through a tube placed in the nose and down into the stomach may be needed to keep the stomach emptied of digestive juices.
After 2 to 3 days of bowel rest, you are given something to eat. If the obstruction has cleared up, no surgery is needed. If the obstruction remains, bowel rest may be continued. If repeated periods of bowel rest fail to clear up the obstruction, surgery to remove the diseased part of the colon may be considered.
