Blind introduction of the Veress needle or the umbilical trocar is the cause of 1 to 4 injuries per 1,000 laparoscopies, particularly in case of abdominal adhesions. The aim of this experimental randomized study was to determine whether the needlescope can improve safety compared with the routinely used syringe test. Adult female rabbits were randomized into two groups of 20. Abdominal adhesions were created surgically in all animals. Three weeks later, a pneumoperitoneum was provoked under general anesthesia and five trocars were introduced into each animal after the needlescope test or the syringe test. The needlescope yielded high sensitivity. Adhesion formations were localized in 95% of the cases. Inversely, the syringe test localized adherences in only 50% of the cases. The number of organ injuries was identical for the two tests: 6.06 versus 6.25%.
