Percutaneous biopsy of bowel lesions: Technique, efficacy and safety

The purpose of this study is to present the indications, rationale and techniques used in minimally invasive percutaneous biopsy of the bowel. Both efficacy and rate of complications were evaluated. A series of 63 patients over a ten-year period were retrospectively reviewed. Techniques using fluoroscopy, ultrasound and CT guidance are described.

Percutaneous biopsy of the bowel is a safe and effective method for obtaining histological samples in selected patients who are not fit for endoscopy or for other technical reasons. Radiologists should be aware of its potential as a valid alternative.
