Introduction Anal fistula surgery is often associated with continence disorders due to transection of the anal sphincter muscles. A comprehensive understanding of the anatomy of the anal canal and fistula can help prevent this outcome. Objective To correlate the anatomy of the intersphincteric anal fistula with the patient's sex using three-dimensi...

Studies have demonstrated the relationships among abnormalities found on imaging, dysfunction, and symptoms remain unclear in female with levator ani muscle damage/avulsion. Therefore, the aim of this study was to investigate correlations among defects in the levator ani muscles, symptoms related to anorectal and/or urinary disorders, dynamic dysfu...

Background: Few studies measured the pre-and postoperative anatomic and functional anal canal using 3-dimensional endoanal ultrasound and anal manometry, and correlated sphincter division with fecal incontinence, severity, and function. Objective: Assess the incidence of fecal incontinence in patients who underwent internal anal sphincter divisi...

Study objectives: To evaluate blood supply in the anal canal, rectal wall and mesorectal fat of men and women, using color Doppler endorectal sonography to establish normal ranges for vascular parameters. Methods: A prospective cross-sectional study conducted at a tertiary-care hospital recruited asymptomatic volunteers (≤50 years). Vascularity pe...

PurposeThis study aims to evaluate pubovisceral muscle and anal sphincter defects in women with previous vaginal delivery and fecal incontinence and to correlate the findings with the severity of symptoms using the combined anorectal and endovaginal 3D ultrasonography with a new ultrasound scoring system. Methods Consecutive female patients with pr...

Background: Numerous studies have described the use of biofeedback therapy for the treatment of anismus. Success rates vary widely, but few data are available regarding factors predictive of success. Objective: Our aim was to evaluate short-term results of biofeedback associated with diet in patients with obstructed defecation because of anismus...

Objectives: To assess the prevalence of polyps in patients with a family history of colorectal cancer, in comparison to asymptomatic individuals with indication for screening. Methods: A prospective study in a group of patients who underwent colonoscopy between 2012 and 2014. Patients were divided into two groups: Group I: no family history of col...

Purpose: We aimed to correlate the course of the anal fistula tract (T), location of the external opening (EO) and internal opening (IO) in anterior (A) and posterior (P) circumference using 3D-US according to Goodsall's rule. Methods: 151 patients with primary ptoglandular Transsphincteric fistulas were examined with 3D-US and compared with surgi...

Objectives: To evaluate anal sphincter anatomy using three-dimensional ultrasonography (3-DAUS) in incontinent women with vaginal delivery, correlate anatomical findings with symptoms of fecal incontinence and determine the effect of vaginal delivery on anal canal anatomy and function. Methods: Female with fecal incontinence and vaginal delivery...

AimWe assessed pubovisceral muscle (PVM) defects, levator hiatal dimensions, and anal sphincter defects using 3-D endovaginal and anorectal ultrasonography in women with previous vaginal delivery and faecal incontinence to determine the relationship between anatomic/functional findings and severity of faecal incontinence symptoms.Method This was a...

Objetivo Avaliar os resultados clínicos, funcionais e morfológicos de pacientes submetidas à esfincterotomia para tratamento de fissura anal, correlacionando os resultados com os fatores que podem interferir com a continência fecal. Método Foram prospectivamente avaliadas pacientes do sexo feminino submetidas à esfincterotomia lateral interna devi...

New ultrasound techniques may complement current diagnostic tools, and combined techniques may help to overcome the limitations of individual techniques for the diagnosis of anorectal dysfunction. A high degree of agreement has been demonstrated between echodefecography (dynamic 3-dimensional anorectal ultrasonography) and conventional defecography...

: Sphincterotomy is used to treat chronic anal fissure, but the length of the sphincterotomy is associated with incontinence. : We used 3-dimensional anal ultrasonography to determine the proportion of the internal anal sphincter that may be divided during lateral internal sphincterotomy in women without predisposing them to a high risk of fecal in...

To determine anatomical and functional pelvic floor measurements performed with three-dimensional (3-D) endovaginal ultrasonography in asymptomatic nulliparous women without dysfunctions detected in previous dynamic 3-D anorectal ultrasonography (echo defecography) and to demonstrate the interobserver reliability of these measurements. Asymptomatic...

Management of patients with obstructed defecation syndrome is still controversial. To analyze the efficacy of clinical, clinical treatment followed by biofeedback, and surgical treatment in patients with obstructed defecation, rectocele and multiple dysfunctions evaluated with echodefecography. The study included 103 females aged 26-84 years with o...

Knowledge of risk factors is particularly useful to prevent or manage pelvic floor dysfunction but although a number of such factors have been proposed, results remain inconsistent. The purpose of this study was to evaluate the impact of aging on the incidence of posterior pelvic floor disorders in women with obstructed defecation syndrome evaluate...

Aim The effect of vaginal delivery and ageing on the anatomy of the anal canal was assessed using three-dimensional anorectal ultrasound to determine the interobserver reliability. Method One-hundred and eighteen asymptomatic women without sphincter damage were grouped according to parity and mode of delivery. They were then stratified by age (≤50...

The purpose of the study was to describe a novel three-dimensional dynamic anorectal ultrasonography technique (dynamic 3-DAUS) for assessment of perineal descent (PD) and establishment of normal range values, comparing it with defaecography. Secondarily, the study compares the ability of the two techniques to identify various pelvic floor dysfunct...

Surgery for anal fistula is often associated with continence disorders due to the transection of sphincter muscles. Extensive knowledge of anal canal anatomy and anal fistula can help prevent this outcome. This study aimed to correlate the anatomical conformation of the anal canal, the fistula track, and the internal opening according to sex and he...

Anismus is a prevalent functional cause of outlet delay. It is characterized by symptoms of obstructed defecation associated with paradoxical contraction of the pelvic floor muscles. To evaluate the ability of two dimensional anal ultrasonography to identify anismus patients with paradoxical contraction or normal relaxation, comparing findings with...

The aim of this study was to identify criteria for three-dimensional anorectal ultrasonography (3D-AUS) to assess the response of rectal cancer to chemoradiotherapy; the 3D-AUS results were compared with the histopathological findings of the resected specimen. Thirty-five patients underwent 3D-AUS and were grouped according to the presence (GI; n =...
