Comparison of direct trocar and veress needle insertion in the performance of pneumoperitoneum in laparoscopic cholecystectomy.

Veress needle insertion, direct trocar insertion and open technique are different methods of establishing pneumoperitoneum to perform a successful laparoscopic procedure. We conducted this study to compare the use of a Veress needle and direct trocar insertion to create pneumoperitoneum. 274 laparoscopic cholecystectomy operations were evaluated. There were no significant differences in the age and gender between Veress needle and direct trocar entry groups. In this study we have seen that the complication rate while performing pneumoperitoneum by direct trocar entrance was less than in Veress needle usage. Direct trocar entrance also reduces the operation time. In laparoscopic cholecystectomy the direct trocar entrance method is a more reliable and less time consuming method than Veress needle usage.
