Hennessey, James V., Joseph A. Chromiak, Shirley
DellaVentura, Jennifer Guertin, and David B. MacLean. Increase
in percutaneous muscle biopsy yield with a suction-enhancement
technique. J. Appl. Physiol. 82(6):
1739-1742, 1997. The percutaneous muscle biopsy technique is used
in clinical practice and biomedical research. We developed a new
enhanced-suction technique [suction-enhancing nipples
(SEN)] and compared it with techniques currently in practice by
assessing biopsy yields on anesthetized pigs. We applied the enhanced-suction technique to human subjects participating in a
clinical trial. In the pig, there was a mean 91% (1.9-fold) increase
in the size of the samples obtained with the 4-mm needle when SEN was
used and a mean 507% (fivefold) increase in sample size when the SEN
was applied to the 6-mm needles. Nine passes of the 6-mm needle with
SEN obtained from five consecutive human subjects yielded a mean
individual sample size of 109.4 mg or 219.4 mg per needle pass when
using the double-sample technique. Adequate tissue samples for
histomorphometric and other analyses were obtained in all samples
obtained. The percutaneous muscle biopsy performed with enhanced
suction using inexpensive, readily available nipples enhances tissue
yield two- to fivefold.
