About the book
Functional gastrointestinal disorders are common disorders that are characterized by persistent and recurring gastrointestinal symptoms, not explained by structural or biochemical abnormalities. In keeping with this definition, this book addresses anorectal symptoms, the etiology of which is currently unknown or is related to the abnormal functioning of normally innervated and structurally intact muscles, or is attributed to psychological causes. Anorectal disorders are a common reason for visits to both primary care physicians and gastroenterologists.
This book reviews the most common benign anorectal disorders, including fecal incontinence (defined as the recurrent uncontrolled passage of fecal material for at least 3 months), functional anorectal pain (three types described: proctalgia fugax, levator ani syndrome, and unspecified), functional defecation disorders (characterized by paradoxical contraction or inadequate relaxation of the pelvic floor muscles during attempted defecation and/or inadequate propulsive forces during attempted defecation), hemorrhoids (an extremely common condition, affecting approximately 10 million persons per year, also called piles, are swollen veins in the anus and lower rectum, similar to varicose veins), anorectal abscesses and fistulae (originated from an infected anorectal gland and thought to be a spectrum of the same disease: include Crohn’s disease, radiation proctitis, foreign body, prior anal surgery, infections such as HIV, tuberculosis, or actinomycosis, and malignancy), anal fissures (a linear or oval shaped tear in the anal canal starting just below the dentate line extending to the anal verge).
This title will provide guidelines and treatment options for all patients suffering from anorectal disorders.
