Summary
Computed tomography (CT) is effective for diagnosing sigma diverticulitis, identifying complications like perforations, abscesses, and fistulas with high sensitivity, aiding surgical planning.
Area of Science:
- Gastroenterology
- Radiology
- Surgical Diagnostics
Background:
- Sigma diverticulitis is a common condition requiring accurate diagnosis.
- Imaging plays a crucial role in evaluating the severity and complications of diverticulitis.
Purpose of the Study:
- To evaluate the diagnostic accuracy of computed tomography (CT) for sigma diverticulitis.
- To compare CT findings with colon monocontrast enema and histopathology.
Main Methods:
- A study of 32 patients operated on for sigma diverticulitis.
- Both CT and monocontrast enema were performed in 30 patients; CT only in 2.
Main Results:
- CT showed high sensitivity for inflammatory wall changes (89.7%) and pericolic reactions (89.7%).
- CT demonstrated superior sensitivity for covered perforations (76.5%) compared to contrast enema (46.7%).
- CT achieved 100% sensitivity for detecting abscesses and fistulas.
Conclusions:
- CT is valuable for identifying extraluminal changes and complications in sigma diverticulitis.
- CT findings can help classify inflammation severity and guide surgical decisions.
