Functional Correlates of Anal Canal Anatomy: Puborectalis Muscle and Anal Canal Pressure

Abstract

BACKGROUND:Resting and squeeze pressures in the anal canal are thought to reflect the contributions of the internal anal sphincter (IAS) and the external anal sphincter (EAS) respectively. Role of the puborectalis muscle (PRM) in the genesis of anal canal pressure is not known.OBJECTIVES:To determine the functional correlates of anal canal anatomy.METHODS… (More)
