Abstract

Objectives: This study describes the epidemiology of functional anorectal abnormalities on high–resolution anorectal manometry (HRAM) and compares HRAM metrics between people with normal pushing maneuvers and patients having dyssynergic defecation (DD). Subjects and methods: A retrospective descriptive study on 204 patients who performed HRAM from August 2020 to January 2023. Results: The study included 70 males and 134 females; the mean age was 51.0 ± 16.0. 78.4% of patients had incomplete evacuation feeling and over 50% had symptoms related to bowel habit disorders, stool apperarance changes. There was significant difference between the males and females in anal canal length, anal canal resting and squeeze pressure. Type II was the most common in DD and the rectal sensation levels were different between two groups (normal pushing maneuver and dyssynergic defecation). Conclusions: Type II was the most predominant among dyssynergic defecation patients. There was difference in HRAM metrics between males and females, normal pushing maneuver group and dyssynergic defecation group.
