Abstract
PURPOSE: The purpose of this work was to examine the accuracy and safety of CT-guided core biopsy of gastrointestinal wall lesions. METHOD: We reviewed over 1,200 CT-guided abdominal core biopsy results from 1989 through 1998. Forty-five were from gastrointestinal wall lesions (16 gastric, 3 duodenal, 7 small intestine, and 19 colon). RESULTS: A definitive histologic diagnosis was obtained from the core biopsy in 41 patients (91%) without complication. The gastric lesion diagnoses were mesenchymal tumor of smooth muscle origin (eight), lymphoma (one), adenocarcinoma (three), and normal (one). Duodenal core biopsy diagnoses were inflammation (one) and normal (one). Small intestinal core biopsy diagnoses were non-Hodgkin lymphoma (four), metastatic leiomyosarcoma (one), carcinoma (one), and tuberculosis (one). Colon core biopsy diagnoses were carcinoma (11), lymphoma (2), actinomycosis (2), granulomatous inflammation (1), metastatic squamous cell carcinoma (1), chronic abscess (1), and mesenchymal tumor of smooth muscle origin (1). CONCLUSION: Percutaneous CT-guided core needle biopsy from gastrointestinal wall lesions is safe and accurate, especially in submucosal lesions, and should be considered in selected cases with negative endoscopic biopsy or in which endoscopic biopsy is not possible.
