Objectives: To use three-dimensional anorectal ultrasonography (3D-US) to evaluate the outcome of ligation of the intersphincteric fistula tract (LIFT) in patients with crypto-glandular transsphincteric fistula and describing the patterns of healing, failure, and recurrence rate.
Methods: After classifying the fistula and determining the length of the sphincter muscle to be transected, the patients were submitted to LIFT. The accuracy of pre- and postoperative 3D-US with 360° endoprobe (16 MHz) with automatic scanning and clinical findings was evaluated against surgical findings.
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: To assess the incidence of fecal incontinence in patients who underwent internal anal sphincter division for anal fissure or intersphincteric anal fistula and correlate severity of symptoms with percentage of divided muscle, anatomical measurements, and anal pressures.
Design: Prospective cohort study.
Background: Biofeedback is an effective method of treatment for fecal incontinence but there is controversy regarding factors that may be correlated with its effectiveness.
Objective: To evaluate the efficacy of biofeedback in the treatment of fecal incontinence, identifying the predictive factors for unsuccessful treatment.
Methods: Consecutive female patients who had fecal incontinence and were treated with a full course of biofeedback were screened.
Context: Management of patients with obstructed defecation syndrome is still controversial.
Objective: 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.
Methods: The study included 103 females aged 26-84 years with obstructed defecation, grade-II/III rectocele and multiple dysfunctions on echodefecography.
Context: The correlation between vaginal delivery, age and pelvic floor dysfunctions involving obstructed defecation is still a matter of controversy.
Objectives: To determine the influence of age, mode of delivery and parity on the prevalence of posterior pelvic floor dysfunctions in women with obstructed defecation syndrome.
Methods: Four hundred sixty-nine females with obstructed defecation syndrome were retrospectively evaluated using dynamic 3D ultrasonography to quantify posterior pelvic floor dysfunctions (rectocele grade II or III, rectal intussusception, paradoxical contraction/non-relaxation of the puborectalis and entero/ sigmoidocele grade III).
Context: Since anorectocele is usually associated with mucosa prolapse and/or rectal intussusceptions, it was developed a stapled surgical technique using one circular stapler.
Objective: To report the results of Transanal Repair of Rectocele and Rectal Mucosectomy with one Circular Stapler (TRREMS procedure) in the treatment of anorectocele with mucosa prolapse in a prospective multicenter trial.
Methods: It was conducted by 14 surgeons and included 75 female patients, mean aged 49.
Context: 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.
Objective: To evaluate the ability of two dimensional anal ultrasonography to identify anismus patients with paradoxical contraction or normal relaxation, comparing findings with manometric measurements.
Types of pelvic floor dysfunctions in nulliparous, vaginal delivery, and cesarean section female patients with obstructed defecation syndrome identified by echodefecography.

Purpose: This study aims to show pelvic floor dysfunctions in women with obstructed defecation syndrome (ODS), comparing nulliparous to those with vaginal delivery or cesarean section using the echodefecography (ECD).
Materials And Methods: Three hundred seventy female patients with ODS were reviewed retrospectively and were divided in Group I-105 nulliparous, Group II-165 had at least one vaginal delivery, and Group III-comprised of 100 patients delivered only by cesarean section. All patients had been submitted to ECD to identify pelvic floor dysfunctions.
Background: Three-dimensional anorectal ultrasound (3-DAUS) scanning provides accurate information on tumor size and its relation to the anal muscles. The purpose of this study was to evaluate the ability of 3-DAUS to assess response to radiochemotherapy (RCT) for rectal cancer by comparing 3-DAUS images to pathological findings.
Methods: Twenty-five patients (mean age 52.
Background: Anorectal endosonography is actually the main image exam to evaluate some anorectal diseases.
Aim: To show the three-dimensional endosonography importance in the anal canal anatomic evaluation and the anorectal diseases diagnosis.
Methods: Seventy four anorectal ultrasound were performed, 23 normal individuals (13 women) and 51 patients (33 women) with benign and malignant diseases.
Purpose: Develop an experimental model of laparoscopic hand-sewn suture in colon of dogs to be specially used for surgeons' training.
Methods: Forty male dogs were operated on, weight between 15 and 20 kg, from the laboratory of the Veterinary School of the State University of Ceara. They were distributed within two groups with 20 animals each: GI--The colonic wall incision was done with an electrical scalpel followed by haemosthasia and GII--The colonic wall incision was performed with a scissors.
