Summary

Defecatography is a valuable diagnostic tool for chronic constipation, identifying functional and organic causes of anorectoperineal symptoms when other methods fail. This study highlights its importance in evaluating complex cases of rectal dysfunction.

Area of Science:

  • Gastroenterology
  • Colorectal Surgery
  • Diagnostic Imaging

Background:

  • Chronic constipation significantly impacts quality of life, often stemming from complex anorectoperineal dysfunctions.
  • Conventional diagnostic methods may not fully elucidate the underlying causes of severe or persistent constipation.

Purpose of the Study:

  • To evaluate the diagnostic utility of defecatography in patients with chronic constipation and anorectoperineal symptoms.
  • To assess the prevalence of functional and organic abnormalities contributing to defecatory dysfunction.

Main Methods:

  • A retrospective study of 65 patients with chronic constipation over 64 months.
  • Standardized defecatography protocol using contrast material and specific imaging techniques.
  • Analysis focused on pubo-rectal beam function, pelvic floor dynamics, and rectal morphology.

Main Results:

  • Functional abnormalities were the predominant findings, including insufficient pubo-rectal laxity (29.23%) and paradoxical contractions (16.92%).
  • Rectocele and pelvic floor descent were observed in significant proportions of patients.
  • Organic causes were less common, with rectal intussusception identified in only 1.53%.

Conclusions:

  • Defecatography is highly effective in diagnosing functional and organic causes of constipation with anorectoperineal symptoms.
  • The procedure is crucial for pre- and post-surgical assessment in therapeutic and reconstructive interventions.
  • It provides essential insights when other diagnostic approaches are inconclusive.
