[null,null,null,"Sommario/riassunto","This book offers an interdisciplinary reference for diagnosis and treatment of anal fistula. First chapters provide state of the art review of anatomy, etiology, sign and symptoms, medical findings and differential diagnosis of anal fistula. The following chapters cover surgical and non-surgical treatment of anal fistula. Other important chapter presents diagnosis and treatment of special anal fistula, including anal fistula of Crohn's disease, anal fistula in infants, tuberculous anal fistula, and anal fistula associated with AIDS. It will appeal to proctologists and surgeons in gastroenterology."]
