Wear, tear, and possible contamination after 100 clinical cycles of three test trays were investigated on laparoscopic "tracer" instruments in a prospective clinical study. Failure was below 4 per 100 laparoscopies, and remaining contamination was detected after passing 100 cycles in 20%, which happened to control instruments from open surgery as well. Further clinical data of contamination levels for apparently clean instruments must be collected to evaluate and correlate to microbiological testing.
