[Decreasing the surgical risk of laparoscopy by using a newly developed, blunt trocar]

Laparoscopy is one of the most frequent interventions used in operative gynaecology. Because of the possible, occasionally grave complications through the use of the trocar forms applied so far, we have developed a new blunt trocar. By using this trocar throughout 1889 interventions, we have had no complications which could be ascribed to the use of this blunt instrument. The advantage of this trocar lies in the avoidance of the possible and feared injuries to the intestines and vessels. Even though overall complication rates in laparoscopy are low and there is no evidence of a statistically significant reduction compared with the use of the sharp trocar, the advantages of the blunt trocar are obvious. There is only one disadvantage, namely the slightly prolonged training time of the younger colleagues, as well as the theoretical possibility of a prolapse of the omentum. Nevertheless, in our opinion, the use of the blunt trocar is advisable to reduce the complication rate in laparoscopy.
