Summary

Computed tomography (CT) accurately stages acute perforated sigmoid diverticulitis in most patients, aiding disease severity assessment and surgical planning. This imaging tool is valuable for diagnosing perforation sites and extraluminal contrast material.

Area of Science:

  • Gastroenterology
  • Radiology
  • Surgical Pathology

Background:

  • Acute perforated sigmoid diverticulitis is a serious condition requiring accurate staging.
  • The Hinchey classification is a standard method for grading perforated diverticular disease.
  • Computed tomography (CT) is a key imaging modality in evaluating abdominal conditions.

Purpose of the Study:

  • To evaluate the diagnostic accuracy of CT in staging acute perforated sigmoid diverticulitis.
  • To correlate CT findings with the Hinchey classification.
  • To determine CT's value in surgical planning for this condition.

Main Methods:

  • Retrospective analysis of 30 patients with acute perforated sigmoid diverticulitis.
  • CT scans were performed prior to surgical intervention.

  • CT findings were compared with surgical and histopathological reports using the Hinchey classification.

    • Main Results:

    • CT correctly determined the Hinchey stage in 93% of patients.
    • CT identified perforation sites in 86% of cases and contained perforations in 100%.
    • Extraluminal contrast material was detected in 35% of patients with proven perforation.

    Conclusions:

    • CT is a valuable tool for staging acute perforated sigmoid diverticulitis.
    • CT assists in stratifying patients by disease severity.
    • CT findings aid in surgical planning for perforated diverticulitis.
