Summary

Defecography, particularly videoproctography, effectively diagnoses rectal prolapse and associated anorectal disorders. This imaging technique accurately visualizes dynamic changes, aiding in patient assessment and follow-up care.

Area of Science:

  • Gastroenterology
  • Radiology
  • Pelvic Floor Disorders

Background:

  • Pelvic floor and rectal prolapse conditions benefit from advanced diagnostic imaging.
  • Defecography is crucial for understanding pathophysiology and differential diagnosis.

Purpose of the Study:

  • To evaluate the efficacy of defecography in assessing rectal prolapse.
  • To determine the role of videoproctography in diagnosing dynamic anorectal disorders.

Main Methods:

  • 224 patients with rectal prolapse were studied using defecography and videoproctography.
  • Mahieu's technique was employed with slight filter position modification.
  • Other examinations included sigmoidoscopy, occult blood tests, and barium enemas to exclude organic colon conditions.

Main Results:

  • Mucosal prolapse (71%) was more common than intussusception (34%).
  • External rectal prolapse occurred in 12 cases of anorectal intussusception.
  • Rectal prolapse was frequently associated with rectocele, perineal descent, and puborectalis muscle syndrome (96 cases).

Conclusions:

  • Videoproctography effectively depicts dynamic ampullary changes and anorectal normalization.
  • Defecography demonstrates good capability in identifying rectal wall function abnormalities.
  • Videoproctography is a low-radiation, non-invasive, and easily performed examination suitable for patients with anorectal disorders.
