Randomized clinical trial of Lichtenstein patch or Prolene Hernia System for inguinal hernia repair.
BACKGROUND
In this randomized prospective study the short- and long-term outcomes of patients undergoing inguinal hernia repair with either Lichtenstein mesh or the Prolene Hernia System (PHS) were evaluated.


METHODS
Postoperative pain and time to return to work, driving and sporting hobbies were recorded after 300 inguinal hernia repairs done by one of the two methods. Long-term sequelae and complications were assessed at follow-up visits 1 week, 1 month and 1 year after the operation.


RESULTS
The median duration of operation for unilateral primary hernia was 37 min for the Lichtenstein operation and 27 min for the PHS procedure (P < 0.001). Postoperative pain was similar after both operations. Median sick leave was 7 days in both groups. Time to driving a car was 4 versus 3 days, and time to return to sporting hobbies 13 versus 11 days, in the Lichtenstein and PHS groups, respectively. Apart from a residual femoral hernia after Lichtenstein repair, no recurrent inguinal hernias were detected.


CONCLUSIONS
Both Lichtenstein and PHS methods resulted in rapid recovery and low recurrence rates. The PHS operation was significantly quicker.
