BACKGROUND Despite an increased propensity to primary failure in forearm arteriovenous fistulae compared with upper arm fistulae, forearm fistulae remain the preferred primary access type for chronic hemodialysis patients. In a high risk patient population with multiple medical comorbidities associated with requirement for intravenous access we compared the rates of access failure in forearm an...

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...

The report presented is an analysis of 30 patients with an oroantral Fistula. The tooth most frequently involved was the upper first molar, followed by the second molar and second premolar. The highest incidence was seen in the third and the fourth decades of life and the lowest incidence in the second decade. In this study intercurrent sinusitis was the most obvious cause of the chronic oroant...

Purpose: The purpose of this study is to check up the possible usage of a new approach when treating oroantral communication (OAC) which includes the usage of platelet-rich fibrin (PRF). Methods and materials: 6 patients (4 women and 2 men) participated in this study with oroantral communications after the extractions of maxillary molars. The OAC was closed surgically using PRF membranes. The c...

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...

The authors present the problems of oroantral fistula by reviewing the possibilities of surgical treatment. Known and less known operative methods are described and their advantages and disadvantages analysed. The object of this study is to remind the reader of the iatrogenic possibility of the occurrence of an antrooral communication and possibility of the development of a fistula and infectio...

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 ...

The aim of this study was to evaluate and analyze the occurrence, characteristics and treatment outcome of oroantral fistula in 29 patients from Sept 2004 to Nov 2009. These patients were examined both clinically and radio-logically for oroantral fistula. Data regarding the age, gender, cause and site of fistula and treatment outcome was evaluated and reviewed. The age range was 18-60 years wit...

Oroantral communication (OAC) is a common complication following extraction of maxillary premolar and molar teeth. This is due to the close anatomic proximity of the roots of these teeth to the maxillary sinus. The most frequent methods utilized in the office described in the literature to close an oroantral communication involve the use of a buccal or palatal rotational advancement flap or use...
