Summary
Percutaneous mesenteric biopsy is a complex procedure due to deep lesion location, surrounding bowel, and vascularity. This guide offers insights into techniques and potential complications for successful mesenteric biopsy.
Area of Science:
- Interventional Radiology
- Abdominal Imaging
- Gastrointestinal Oncology
Background:
- Mesenteric lesions present unique challenges for biopsy, including deep abdominal location, proximity to bowel, complex vasculature, and high mobility.
- These factors can make percutaneous biopsy technically demanding for radiologists.
Purpose of the Study:
- To provide a comprehensive guide to percutaneous mesenteric biopsy.
- To inform radiologists on techniques, pitfalls, and complications associated with this procedure.
Main Methods:
- Review of available literature and experience from two high-volume teaching centers.
- Discussion of imaging pitfalls, ultrasound (US) and computed tomography (CT) guidance techniques.
- Analysis of potential complications such as hemorrhage and bowel injury.
Main Results:
- Percutaneous mesenteric biopsy is feasible despite anatomical challenges.
- Careful pre-procedural imaging assessment and tailored technique selection are crucial.
- Awareness of potential complications guides safe practice.
Conclusions:
- Percutaneous mesenteric biopsy is an essential tool for diagnosing mesenteric lesions.
- This overview aims to enhance radiologist confidence and competence in performing mesenteric biopsies.
- Adherence to best practices minimizes risks and optimizes diagnostic yield.
