To assess the accuracy of preoperative CT scanning in predicting the stage of severity of perforated diverticulitis.
Key Findings:
64% of patients were correctly staged by CT scanning according to the Hinchey classification.
High inter-observer agreement with a discrepancy rate of 7%.
Use of rectal contrast did not significantly improve accuracy of CT scanning.
Interpretation:
CT scanning is a reliable method for staging perforated diverticulitis, with a notable accuracy rate, but the addition of rectal contrast does not enhance this accuracy.
Limitations:
Retrospective design may introduce selection bias.
Limited to patients who underwent surgery at specific hospitals within a defined time frame.
Conclusion:
Preoperative CT scanning is effective in staging perforated diverticulitis, aiding in treatment decision-making.
