A Systematic Review of Stapled Hemorrhoidectomy

Abstract

INTERNAL HEMORRHOIDS develop when cushions of vascular tissue in the anus undergo pathological change. These cushions have an important role in maintaining continence because they function, along with the internal anal sphincter, to allow the complete closure of the anal canal.¹ Hemorrhoids can be thought of as symptomatic aggregations of this subepithelial tissue² that may cause bleeding, mucosal or fecal soiling, itching, and occasional pain.¹ The prevalence of hemorrhoids is estimated at between 4% and 34%.³
