This review highlights acute colonic disorders, focusing on less common obstructions like volvulus and hernias, and nonobstructive dilatation causes such as toxic megacolon. Radiologic features are emphasized for diagnosis.

Area of Science:

  • Gastroenterology
  • Radiology
  • Colorectal Surgery

Background:

  • Acute colonic disorders present diverse clinical scenarios.
  • Understanding uncommon causes of obstruction and dilatation is crucial for timely diagnosis.

Purpose of the Study:

  • To review specific colonic disorders with acute clinical presentations.
  • To emphasize the radiologic features of these conditions.

Main Methods:

  • Literature review of colonic disorders.
  • Analysis of pathogenesis, clinical aspects, and radiologic findings.

Main Results:

  • Common causes of colonic obstruction include volvulus, intussusception, and hernias.
  • Pseudo-obstructions and toxic megacolon are frequent causes of nonobstructive colonic dilatation.

  • Miscellaneous disorders like colonic perforation, leukemia complications, and pseudomembranous colitis are also discussed.

    • Conclusions:

    • Radiologic features are key in diagnosing acute colonic disorders.
    • Comprehensive understanding of varied colonic pathologies aids clinical management.
