[Intervention ultrasound in abdominal tumors--an analysis of 183 cases]

The results of ultrasound guided percutaneous fine needle biopsy in 183 cases of suspected abdominal space-occupying lesions are reported. The accuracy of fine needle biopsy was 84.1% (127/151) in malignant tumors and 96.6% (28/29) in benign tumors By B-ultrasonography, intratumoral injection of absolute alcohol was done in 17 cases of advanced hepatic cancer. The tumor markedly reduced in size from 12 x 12 cm to 3.5 x 3.5 cm in 1 case, reduced by half in 2 but enlarged again 1 month later, remained unchanged in 2 and progressed in the remaining patients. A 50% decrease in AFP was seen in 4 patients. Eleven cases of liver, kidney or ovarian cyst were treated by intracystic injection of absolute alcohol which led to progressive reduction even disappearance of the cyst. Intervention ultrasonography, being simple, safe, accurate and having less complications, is useful not only for diagnosis but also for treatment of diseases in the abdomen.
