Anal sphincter function in rectal intussusception and high and low "take-off" external rectal prolapse-A prospective observational study.

ABSTRACT:

Aim

Rectal intussusception (RI) and external rectal prolapse (ERP) are associated with anal sphincter dysfunction. The aim of this study was to examine sphincter function with anal acoustic reflectometry (AAR) in RI and two distinct phenotypes of ERP termed high and low "take-off".

Methods

A prospective study of patients with RI and ERP attending a tertiary pelvic floor unit. Clinical data, AAR, and conventional anal manometry were analysed according to the Oxford prolapse grade.

Results

A total of 108 (102 [94%] female, median age 62 years [range: 26-95]) patients were recruited into three groups according to prolapse grade: Oxford grades I and II (intrarectal RI, n = 34), Oxford grades III and IV (intra-anal RI, n = 35) and Oxford grade V (ERP, n = 39). As the grade
