Fine-needle aspiration biopsy of colonic masses.
Between 1989 and 1996, fine-needle aspiration biopsy was performed in 22 patients with palpable colonic masses. In all of these patients colonoscopic examination was either not possible or could not be carried out successfully. The results of aspiration biopsy were confirmed by surgery and histopathological examination of the tissue. Aspiration biopsy correctly diagnosed all except one case. It identified all cases of colonic cancer. One patient with colonic tuberculosis was also diagnosed correctly. However, in another patient with colonic tuberculosis, aspiration biopsy showed only nonspecific changes in the form of inflammatory and epithelial cells. There were no false-positive results or complications from the procedure. It is concluded that fine-needle aspiration biopsy is a simple, rapid, and accurate method of diagnosing palpable colonic masses in patients in whom a colonoscopy is not possible or cannot be performed satisfactorily.
