Objective
The aim of this study was to evaluate hernia appearance at the trocar site after laparoscopic treatment of primary or incisional ventral hernias using an intraperitoneal prosthetic mesh. Chronic pain at the trocar site and primary hernia recurrence were also evaluated.
Patients and methods
Two-hundred and twenty-six consecutive patients who underwent a standardized laparoscopic hernia repair for primary or incisional ventral hernia at our centre between January 2000 and December 2008 were included. All patients had clinical and radiological examinations. Primary end points were port site hernia and the occurrence of chronic trocar site pain. Secondary end point was primary hernia recurrence.
Results
Seventy-eight patients were excluded: 6 declined to participate, 48 were unreachable, and 24 did not meet the inclusion criteria (nine underwent a single site laparoscopic approach, ten died of unrelated disease, three were unable to visit the hospital and two had relocated). After exclusion, 148 remained in our study. Mean follow-up was 49 ± 12.6 months. Mean age at the time of surgery was 60 years (range, 28–83) In total, 504 port sites were clinically and radiologically evaluated, and only one (0.02%) had secondary herniation. Three patients (2.0%) had a recurrent hernia, and 14 (9.5%) had developed chronic pain at time of assessment. Nine patients (6.1%) were re-operated for the recurrent hernia before the follow-up evaluation. The overall recurrence rate is, therefore, 8.1%. Only two minor complications and no major complications occurred after surgery. No mortality was observed.
Conclusion
Laparoscopic repair for primary or incisional ventral hernias is a safe surgical approach, with low rates of hernia recurrence and a low morbidity rate. When fascial closure is maintained for 10 mm port sites, the incidence of port site hernias is very low. Five millimetre ports do not require closure.
