Enterovesical fistulas: diagnosis and management

Abstract

Enterovesical fistula (EVF) is an abnormal communication between the intestine and the bladder. It represents a rare complication of inflammatory or neoplastic disease, and traumatic or iatrogenic injuries. The most common aetiologies are diverticular disease and colorectal carcinoma. Over 75% of affected patients describe pathognomonic features of pneumaturia, faecaluria and recurrent urinary tract infections. The diagnosis of EVF can be challenging, and frequently patients are monitored for months before the condition is recognised and treated effectively. Diagnostic tools include laboratory tests, imaging studies and endoscopic procedures. Although conservative management can be attempted in selected patients, in most cases, the treatment is mainly based on surgical interventions. Recently, the laparoscopic approach to EVF has been shown to be safe and effective. Although it is a rare condition in a general surgery setting, EVF is a challenging condition leading to high morbidity and mortality rates.

Enterovesical fistula caused by regressive change of non-Hodgkin's lymphoma: A case report

“…The Taipei Veterans General Hospital prefers to use CT and magnetic resonance imaging techniques to identify the fistula tract, as they provide a higher detection rate compared with endoscopy or radiographic examination. The accuracy of these diagnostic tests may be associated with the location and characteristics of EVF (1,6). For example, cystourethrography was arranged for the present patient, however, no contrast outside the bladder was shown.…”

“…As spontaneous closure of the fistula is typically rare, surgical resection is preferred for the majority patients with EVF (1,6). The outcome of surgical resection is good and recurrence is uncommon for patients with benign disease or nonradiation-induced fistulae (1,6), as well as primary …”

Enterovesical Fistula Complicating Myomectomy: A Case Report

“…It is an uncommon disease which occurs most frequently in advanced stage malignancies or from traumatic or iatrogenic injuries [1]. Based on the bowel segment involved, it can be divided into colovesical (the commonest form), rectovesical, ileovesical and appendicovesical fistula [3]. Diverticulitis is the most common aetiology which accounts for 50% -70% of cases [3].…”

“…Pneumaturia, fecaluria and recurrent urinary tract infections are common methods of presentation in enterovesical fistula [5] [6]. Diagnosis of this disease is sometimes challenging and patients may be monitored for months before recognition of this disease [3].…”
