What are the treatments for Diverticular Disease ?
Diverticulitis can attack suddenly and cause complications, such as
                
- an abscessa painful, swollen, pus-filled area just outside the colon wallcaused by infection  - a perforationa small tear or hole in the diverticula  - peritonitisinflammation of tissues inside the abdomen from pus and stool that leak through a perforation  - a fistulaan abnormal passage, or tunnel, between two organs, or between an organ and the outside of the body  - intestinal obstructionpartial or total blockage of movement of food or stool through the intestines
                
These complications need to be treated to prevent them from getting worse and causing serious illness. In some cases, surgery may be needed.
                
Abscess, perforation, and peritonitis. Antibiotic treatment of diverticulitis usually prevents or treats an abscess. If the abscess is large or does not clear up with antibiotics, it may need to be drained. After giving the person numbing medication, a radiologist inserts a needle through the skin to the abscess and then drains the fluid through a catheter. The procedure is usually guided by an abdominal ultrasound or a CT scan. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure.
                
A person with a perforation usually needs surgery to repair the tear or hole. Sometimes, a person needs surgery to remove a small part of the intestine if the perforation cannot be repaired.
                
A person with peritonitis may be extremely ill, with nausea, vomiting, fever, and severe abdominal tenderness. This condition requires immediate surgery to clean the abdominal cavity and possibly a colon resection at a later date after a course of antibiotics. A blood transfusion may be needed if the person has lost a significant amount of blood. Without prompt treatment, peritonitis can be fatal.
                
Fistula. Diverticulitis-related infection may lead to one or more fistulas. Fistulas usually form between the colon and the bladder, small intestine, or skin. The most common type of fistula occurs between the colon and the bladder. Fistulas can be corrected with a colon resection and removal of the fistula.
                
Intestinal obstruction. Diverticulitis-related inflammation or scarring caused by past inflammation may lead to intestinal obstruction. If the intestine is completely blocked, emergency surgery is necessary, with possible colon resection. Partial blockage is not an emergency, so the surgery or other procedures to correct it can be scheduled.
                
When urgent surgery with colon resection is necessary for diverticulitis, two procedures may be needed because it is not safe to rejoin the colon right away. During the colon resection, the surgeon performs a temporary colostomy, creating an opening, or stoma, in the abdomen. The end of the colon is connected to the opening to allow normal eating while healing occurs. Stool is collected in a pouch attached to the stoma on the abdominal wall. In the second surgery, several months later, the surgeon rejoins the ends of the colon and closes the stoma.
