A colovesical fistula (CVF) represents an abnormal communication between the colon and the bladder. Although CVFs are uncommon, they cause significant morbidity and may markedly affect the patient’s quality of life. Colovesical fistulae most frequently are the consequence of advanced-stage malignant disease, inflammatory bowel disease, and traumatic or iatrogenic injuries. The diagnosis of a CV...

Summary Background Crohn’s disease is an inflammatory, penetrating intestinal associated with fistula formation. Fistulae in can be classified into external and internal fistulae. Internal fistulae form between the gastrointestinal tract another organ include enteroenteric, enterocolic, enterovesical rectovaginal They are significant morbidity a decreased quality of life. Aim To review classifi...

BACKGROUND The pathogenesis of fistulae in Crohn's disease (CD) patients is barely understood. We recently showed that more than two-thirds of CD fistulae are covered with flat, mesenchymal-like cells (transitional cells [TC]) forming a patchy basement membrane. Epithelial-to-mesenchymal transition (EMT) is a process of reprogramming epithelial cells, allowing them to migrate more effectively a...

OBJECTIVES To review our experience in causes, diagnosis and basic principles of surgical treatment of urogenital fistulae. METHODS A retrospective study of 213 patients with different types of urogenital fistulae were reviewed between October 1995 to October 2008. They were analyzed with regard to age, parity, causal factor, mode of treatment and outcome. Patients were also evaluated at two ...

Functional vascular access is a prerequisite for adequate haemodialysis treatment in patients with end-stage renal disease. Autogenous arteriovenous fistulae are considered superior to synthetic grafts and central venous catheters; however, fistulae are not without problems. Fistulae thrombosis has become a clinical challenge in nephrology practice, with relevant clinical implications for dialy...

sialography is the retrograde injection of an iodinated contrast agent into the ductal system of salivary glands and this technique is the only method capable of adequately demonstrating the status of the ductal system. one of the indications of sialography is classification of the salivary ductal system fistulae. this classification has important prognostic and therapeutic values. in the prese...

Fistulae may be defined as direct connections between arteries and veins. Carotid-cavernous fistulae (CCF) are formed secondarily to abnormal communications between the cavernous portion of the carotid artery and the venous plexus of the cavernous sinus. Traumatic fistulae usually result from injuries to the internal carotid artery in its course to the cavernous sinus. These types of fistula fr...

BACKGROUND Uro-genital fistulas, majority of which are vesico-vaginal fistulas (VVF), are a great challenge for women in developing countries. It is commonly caused by prolong obstructed labour and is one of the worst complications of child birth and poor obstetric care. The objective of this descriptive study was to review the cases of genitourinary fistulae so as to understand the magnitude o...

The lacrimal system is comprised of the lacrimal glands for tear production and the lacrimal drainage system for draining tears away from the eyes. Congenital lacrimal system anomalies other than nasolacrimal duct obstruction are uncommon. Congenital lacrimal fistulae are a rare developmental anomaly, and when they occur, they are usually unilateral. Fistulae and diverticulae can originate from...

BACKGROUND The National Kidney Foundation has established detailed guidelines due to increasing morbidity and costs related to haemodialysis vascular access in the end-stage renal disease population. METHODS A quality assurance multidisciplinary committee was formed to implement the Dialysis Outcome Quality Initiative (DOQI) guidelines in September, 1999. Beginning January 2000, a 'Save the V...
