Summary
Real-time sonography is key for diagnosing peri-pancreatic transplant fluid collections, including pancreatitis and vascular issues. Percutaneous intervention guided by sonography can help patients avoid surgery.
Area of Science:
- Transplant Surgery
- Diagnostic Imaging
- Nephrology
Background:
- Post-transplant fluid collections are common complications.
- Accurate diagnosis is crucial for patient outcomes.
- Various imaging modalities exist for assessment.
Purpose of the Study:
- To evaluate the diagnostic and therapeutic utility of imaging techniques for peri-pancreatic-transplant fluid collections.
- To assess the role of sonography, CT, and cystography.
- To determine the effectiveness of percutaneous interventions.
Main Methods:
- Retrospective review of 46 extraperitoneal pancreatic transplant recipients.
- Analysis of sonography, duplex sonography, CT, cystography, aspiration, and drainage.
- Correlation of imaging findings with clinical outcomes.
Main Results:
- Sonography detected 44 abnormalities, including pseudocysts, abscesses, hematomas, urinomas, and vascular occlusions.
- Sonography was superior for detecting fluid collections, pancreatitis, rejection, thrombosis, and duct malfunction.
- CT aided in hematoma diagnosis; cystography identified urinomas.
- Sonographically guided percutaneous intervention benefited 9 patients.
Conclusions:
- Sonography is the primary imaging modality for peri-pancreatic transplant fluid collections.
- Advanced imaging and percutaneous techniques improve diagnosis and management.
- Minimally invasive interventions can obviate the need for surgery.
