Effect of hemorrhoidectomy on anorectal physiology
2010
Purpose
The aim of this study was to determine whether overactivity of the anal sphincter in patients with hemorhhoids is primary or secondary and thus assess indication of lateral internal sphincterotomy to surgical treatment of hemorrhoids. Tonic contraction of the sphincter muscle in patients with advanced stages of hemorrhoids is considered by many authors as a primary cause, and therefore, they complete hemorrhoid surgery with lateral internal sphincteroomy. If hypertension of anal sphincter is secondary during hemorrhoid disease, lateral internal sphincterotomy is not indicated. Although examinations made immediately after sphincterotomy proved no changes of anal continence, certain sequelae of lateral internal sphincterotomy cannot be excluded and may later negatively affect patient’s anal continence.
