The authors are presenting the results of first 50 inguinal hernias treated laparoscopically trough the transperitoneal approach (39 men, 11 women, mean age--42,5 years, 44 uncomplicated and 6 epiploon's incarceration). After the dissection of the hernia's pouch, the parietal defect was covered with Prolène meche in 15 cases, with Marlex in 10 cases and Plastex prosthesis in 25 cases, all of them without fixation. The prosthesis itself was covered with the parietal peritoneum in running suture. The immediate postoperative evolution was good, the patients being able to walk soon after being awake, and without any urinary problems (even in elder patients). The patients left the hospital 24-48 hours after surgery. They were followed-up 2 to 10 months, periodically. The results were good, except 4 patients: 1 case with port-site hematoma (in the right lower quadrant, necessitating open surgery). 2 patients with seromas (vulvar and scrotal) in case of section and abandoning the hernial pouch. 1 patient with prosthesis migration with precocious recidive (24 hours after the operation). We consider the transperitoneal approach as very good in the treatment of uncomplicated and not very large hernias. The easiest and safest technic is that using Prolène prosthesis.
