Summary
Computed tomography (CT) is superior to ultrasound (US) for diagnosing gallbladder (GB) perforation. CT better identifies GB wall defects and associated omental or mesenteric changes, aiding surgical confirmation.
Area of Science:
- Radiology
- Abdominal Imaging
- Surgical Diagnosis
Background:
- Gallbladder (GB) perforation is a serious complication requiring accurate and timely diagnosis.
- Ultrasound (US) and computed tomography (CT) are commonly used imaging modalities for evaluating abdominal pathologies.
Purpose of the Study:
- To compare the diagnostic performance of US and CT in identifying findings associated with gallbladder perforation.
- To determine the superiority of one modality over the other in detecting key features of GB perforation.
Main Methods:
- Retrospective analysis of imaging findings in 13 patients with surgically confirmed GB perforation.
- Comparison of US and CT findings, including pericholecystic fluid, GB wall changes, and associated abdominal abnormalities.
- Evaluation of the detection rates for specific signs of perforation, such as GB wall defects.
Main Results:
- Common US findings included pericholecystic fluid and GB wall layering.
- CT revealed pericholecystic fluid, GB wall defects, and importantly, streaky omentum or mesentery (84.6%).
- CT demonstrated a higher detection rate for GB wall defects (69.2%) compared to US (38.5%).
Conclusions:
- CT is superior to US for the diagnosis of gallbladder perforation.
- CT's ability to visualize pericholecystic fluid, GB wall defects, and surrounding mesenteric changes enhances diagnostic accuracy.
