How do you test for Colovesical fistula?

To diagnose a colovesical fistula, the doctor will perform a computed tomography (CT) scan. To confirm the diagnosis, a test called a cystography, which involves inserting a thin, flexible tube with a camera into the bladder, may be performed. The doctor can use this test to determine if there’s a fistula present.

What is the most common cause of Colovesical fistula?

The most common cause of colovesical fistula is diverticulosis; however, it may be caused by malignant diseases, Crohn’s disease, radiation, etc. The underlying mechanism is the direct extension of a ruptured diverticulum or secondary erosion of a diverticular abscess into the bladder [9, 10].

How do you treat a Colovesical fistula?

Colovesical fistulae can almost always be treated with resection of the involved segment of colon and primary reanastomosis. Fistulae due to inflammation are generally managed with resection of the primarily affected diseased segment of intestine, with repair of the bladder only when large visible defects are present.

Are Colovesical fistulas common?

Colovesical fistulas are uncommon. They’re also known as vesicocolic fistulas. The colon, which helps form stool to be released through the rectum, sits above the bladder.

What happens if you have a colovesical fistula?

A colovesical fistula (CVF) is an abnormal connection between the colon and urinary bladder. Although they are uncommon, CVFs can cause significant morbidity, affect quality of life, and may lead to death, usually secondary to urosepsis .

What kind of blood workup is needed for enterovesical fistula?

Recurrent UTIs with various organisms are consistent with, but not diagnostic of, enterovesical fistulae. Blood studies should include measurement of the blood urea nitrogen (BUN), creatinine, and electrolytes; findings are typically within the reference range. The results of the complete blood cell count (CBC) are typically normal.

Can a CT scan detect colovesical fistulae preoperatively?

In another study, colovesical fistulae identified preoperatively with CT scanning in 12 patients were surgically confirmed in 11 of those patients. CT scanning was also used to exclude fistulae in 20 patients with uncomplicated acute diverticulitis. [ 38]

What should I do if I have a fistula in my colon?

Conservative treatment may include: having a catheter inserted into the bladder to drain fluid that may have seeped into it from the colon The goal of conservative treatment is for the fistula to close and heal on its own. However, surgery may still be necessary in cases where the fistula does not heal on its own.
