[Ultrasound-controlled cutting biopsy for collecting histologic specimens].
The fine-needle puncture under ultrasound guidance has the disadvantage that the material obtained can only be evaluated by cytology. The cutting biopsy cannula represents a compromise between the fine and the Menghini needle. In this way, small tissue cylinders can be attained. The aim of the present study was to investigate to what extent the sampled specimen could be assessed by cytology or histology. Fine-needle puncture resulted in 22 (69%) out of 32 cases in material suitable for cytology. Cutting biopsy led in 34 out of 36 cases (94%) to specimen valid for histology. Thus, cutting biopsy clearly extends our diagnostic tools. It is not yet clear at present whether procedures with a higher risk - such as the Menghini puncture - can be in part replaced by alternative ones.
