Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

Imaging Studies VI: Voiding Cystourethrography and Cystography

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Summary
This summary is machine-generated.

Recurrence after rectal prolapse surgery may be predicted by diabetes mellitus, enterocele, cul-de-sac hernia, and low psoas muscle mass. These factors, identified via magnetic resonance defecography, offer opportunities for preoperative optimization.

Area of Science:

  • Gastroenterology
  • Colorectal Surgery
  • Radiology

Background:

  • Rectal prolapse recurrence after surgical repair is a significant clinical challenge.
  • Previous research on recurrence risk factors has produced inconsistent findings.
  • A limited number of factors have been assessed in prior recurrence risk studies.

Purpose of the Study:

  • To identify preoperative biomarkers for rectal prolapse recurrence after rectopexy.
  • To evaluate the utility of magnetic resonance defecography, anorectal manometry, and balloon expulsion testing in predicting recurrence.
  • To integrate imaging findings with clinical factors for enhanced risk assessment.

Main Methods:

  • Retrospective cohort study utilizing a prospectively maintained rectal prolapse registry.
  • Analysis of 155 patients (145 female) who underwent robotic rectopexy between 2017 and 2025.
  • Comparison of clinical, technical, and imaging parameters between patients with and without recurrence.

Main Results:

  • The overall recurrence rate was 10.3% over a median follow-up of 1295 days.
  • Diabetes mellitus was the only clinical factor significantly associated with recurrence (31.3% vs 5.8%, p < 0.001).
  • Magnetic resonance defecography revealed associations between recurrence and cul-de-sac hernia (75% vs 42.9%, p = 0.015), enterocele (43.8% vs 16.7%, p = 0.018), and lower mean psoas muscle cross-sectional area (12.3 cm² vs 14.3 cm², p = 0.04).

Conclusions:

  • This study is the first to combine MRI findings with clinical factors for rectal prolapse recurrence risk assessment.
  • Potential predictors of recurrence include diabetes mellitus, enterocele, cul-de-sac hernia, and sarcopenia (indicated by low psoas muscle mass).
  • Modifiable factors like diabetic control and sarcopenia present opportunities for preoperative optimization, warranting further large-scale validation studies.
