[Our choice of the method to induce pneumoperitoneum in videolaparoscopic surgery].
BACKGROUND
In laparoscopic surgery, pneumoperitoneum may be obtained either by a blind or an open access technique. These two techniques and the advantages of Hasson technique are compared.


METHODS
Through January 1998 and May 1999, 262 unselected patients underwent laparoscopic surgery; pneumoperitoneum was obtained with a random technique, while in the patients previously operated on the open technique was always performed. In 161 cases (61.5%) pneumoperitoneum was obtained with Hasson technique and in 101 (38.5%) with Veress technique. All the patients were clinically evaluated after surgery and then after 30-40 days. The complications encountered were always associated with the Veress needle blind access: peritoneal space insufflation in 3 cases, greater omentum insufflation in 3 cases, 4 cases of difficult management and only one case of incisional hernia on the umbilical wound.


RESULTS
Our data confirm that Hasson open technique is safer than Veress blind technique as the risk of severe early and late complications is lower.


CONCLUSIONS
The open laparoscopic technique with the Hasson trocar is recommended as it showed to be a quicker, safer and superior technique for obtaining pneumoperitoneum.
