A Family Doctor's Tale - DIVERTICULOSIS

DOC I HAVE DIVERTICULOSIS

Diverticulosis are pouches in the wall of the colon.

Main symptoms are abdominal pain and bloating and constipation.

Treatment is mainly by control of diet, prevention of constipation and antispasmodics for pain.

Rarely diverticulitis  a infection of the colon pouches may be needed to be treated with antibiotics.

Generally prognosis is good.


Diverticulosis is a disorder of the colon or large intestine where there are one or more sac-like pouches(called diverticula) in the walls of the colon.

It is more common in the descending and sigmoid colon.



Diverticulosis becomes more obvious with age.
50% of people over the age 0f 60 years have Diverticulosis.



The exact cause of Diverticulosis is not known.

It has been suggested that a low-fiber diet is the main cause of diverticular disease.

Diverticulosis is common in developed countries where low-fiber diets are common whereas it is rare in Asia and Africa where people eat high-fiber vegetable diets.

Fiber prevents constipation which can make the muscles strain and increase pressure in the colon.

This increased pressure makes the weak spots in the colon lining to bulge out like pouches and become diverticula.



Most cases of Diverticulosis have no or little symptoms.

In the more severe cases, the main symptoms of Diverticulosis are:

1.Abdominal pain or cramps-usually over the left side or over the lower abdomen

2.Bloating

3.constipation

The symptoms can range from mild to severe.

Diagnosis of Diverticulosis is made by:


1.A history of abdominal pain especially on the left lower abdomen, bloating and constipation

2.The physical exam consists of
a.palpation of the left abdomen for tenderness or masses
b.digital rectal exam to detect tenderness or blood.

3.stool may be tested for blood

4.blood tests(WBC,ESR,bood culture) are done for evidence of infection.

5.Xrays of the abdomen and barium enema may be done to show evidence of pouches in the colon

6.Colonoscopy is also done to confirm evidence of diverticulosis and exclude malignant tumours.

Complications of Diverticulosis are:

1.Diverticulitis
Diverticulitis occurs when diverticula become infected with bacteria, viruses or become inflamed.
Bacteria are caught in the pouches and develops into diverticulitis suddenly.

The symptoms and signs of diverticulitis are:
1.abdominal pain usually continuous in the lower left abdomen with tenderness

2.fever due to infection,

3.nausea, vomiting,

4.cramping,

5.constipation

6.rectal tenderness

Diverticulitis can lead to:

1.Bleeding,
rare.
Bleeding can be severe caused by a small blood vessel in a diverticulum that weakens and finally bursts.
Surgery may be needed to stop bleeding if bleeding continues.

2.Abscess, Perforation, and Peritonitis
Often a few days of treatment with antibiotics will cure the diverticulitis.
If the infection gets worse, an abscess which is an infected area with pus may form in the colon.

Small abscesses usually clear up with antibiotics.

More severe abscesses may require drainage of the pus using a catheter.

If pus leaks from perforations in the lining of the colon, then it can cause infection in the abdominal cavity and results in peritonitis.

This is an emergency and requires immediate surgery to clean up the pus in the abdominal cavity and removal of the damaged part of the colon.

3.Intestinal Obstruction
The infection of the diverticula can cause scarring of the lining of the colon resulting in partial or total blockage of the large intestine.

If the obstruction blocks the intestine completely, emergency surgery is required to allow faecal matter to pass through.

A temporary colostomy may be necessary.

4.Fistula
occurs as an abnormal connection between two organs or between an organ and the skin.

It results from the damaged tissues coming together and an opening is left between the two tissues.

Usually the bladder, small intestine, vagina, and skin are the organs involved.

The most common fistula occurs between the bladder and the colon especially in men. This can cause a long-lasting infection of the urinary tract.

Surgery may be necessary to remove the fistula as well as the damaged part of the colon.

5.Urinary tract infections occurs frequently due to the fistula and proximity of the bladder to the infected colon.

6.Discharge of faecal material may occur through a fistula between the colon and vagina in some women.

Treatment of Diverticulosis is by:


Medication:
1.pain medications will relieve any pain symptoms.

2.Antispasmotic medication for spams of the colon

3.Antibiotics may be needed in diverticulitis and complications such as urinary infection and peritonitis.

Diet:
1.high-fiber diet

a.whole grain breads and cereals;
b.fruit like apples and peaches;
c.vegetables like carrots, broccoli, spinach, carrots, cabbage, beans.

2.fiber product such as Metamucil once a day.

3.Avoid nuts, popcorn, pumpkin, and sesame seeds or any food which can cause discomfort in the abdomen

Diverticulitis
1.Antibiotics to treat the infection and inflammation,

2.resting the colon by bed rest, nasogastric suction and a liquid diet

3.hospital stay to prevent complications such as abscess.

4.surgery if the attacks are severe or there are complications.
The surgeon resects the affected part of the colon and then joins the remaining sections.

Surgery is also done for complications such as a fistula or intestinal obstruction.

Emergency surgery may be done for a large abscess, perforation, peritonitis, or continued bleeding.

Prognosis of Diverticulosis is fair.


About 1% develop diverticulitis.
70% of patients with acute attacks of diverticulitis can be treated with medical management and have no further attacks
