Biopsy of bowel wall pathology under ultrasound control.

Primary lesions of bowel wall were biopsied transabdominally in 7 patients. Adequate material for histological diagnosis was obtained in all. In 3 patients previous biopsy performed at endoscopy had failed to establish a diagnosis. In 2 others the area biopsied, i.e., gallbladder, was inaccessible to endoscopy and confirmation would have otherwise required laparotomy. No complications occurred.
