Background:
Access to the peritoneal cavity in laparoscopic procedures is generally achieved by means of a pneumoperitoneum, following introduction of a Veress needle. Because this procedure must be done blindly, it is not without visceral or vascular hazards. Therefore, we sought an alternative technique that might obviate these complications.
Methods:
In a series of 803 patients, a modified Hasson technique was used to obtain a pneumoperitoneum without risking the complications associated with the introduction of a Veress needle.
Results:
The modified Hasson technique proved to be feasible in all cases. No visceral or vascular complications resulted, but 10 patients had a transient serous discharge. Follow-up ranged between 5 and 52 months.
Conclusion:
The modified Hasson technique should always be used in laparoscopic procedures.
