Colovesical fistula secondary to hernia mesh migration: an unusual incident

Abstract

We evaluated a 27-year old male with pneumaturia and fecaluria with a past history of right inguinal hernia repair. Though, cystoscopy and contrast enhanced computed tomography did not furnish any evidence to arrive at a diagnosis, interestingly, colonoscopy revealed a mesh in the sigmoid colon making apparent the diagnosis of colovesical fistula secondary to mesh migration. Later, surgical removal of the mesh from the sigmoid colon with rent closure of the fistulous opening was done successfully. Our case thus, highlights the vital role of common diagnostic tool like colonoscopy in making an uncommon diagnosis.

Migration of a bladder diverticulum stone into the rectum revealing an advanced rectal process

“…An abnormal connection between 2 separate cavities is referred to as a fistula. When it involves the colonic tract and the bladder, it is known as a colovesical fistula [1 , 2] . The exact incidence of colovesical fistulas is still unknown.…”

Colovesical fistula in a young adult due to sigmoid colon diverticulitis undetected in computed tomography: Case report and review of literature

“…The presence of an abnormal communication between two different cavities is called fistula and when it involves the colon tract and the urinary bladder is defined as a colovesical fistula [ 1 , 2 ]. This type of fistula is usually related to inflammatory processes or neoplasm conditions.…”

“…Colovesical fistula is the most common enterovesical fistula type, which is the existence of a pathological communication between the colon and urinary bladder [ [1] , [2] , [3] ]. Diverticular disease induces these conditions in 65–75% of the enterovesical fistula cases [ 1 , 2 ]. Enterovesical fistulas are associated with high morbimortality [ 3 , 4 ].…”
