Long-term recurrence after laparoscopic surgery of inguinal hernias.

Laparoscopic treatment of inguinal hernias has expanded rapidly during the last decade. Several studies have evaluated the early results of this technique, and the rate of recurrence was estimated less than 5% with a range from 0.5% to 10%. The long-term recurrence after such treatment is still not well known. This study reports the 2 year follow-up of laparoscopic treatment of 236 inguinal hernias (220 patients) from January 1996 to December 1997. All patients were contacted by telephone, 196 (90%) (193 men and 3 women) were examined by a senior surgeon. The average time from operation to examination was 34 months (range 20-42 months). We observed a 15% recurrence rate (35 hernias in 34 patients) of which 5% (12 cases) were symptomatic but 10% (23 cases) were totally asymptomatic and diagnosed on clinical examination. The postoperative inguinal haematoma and the physical activity of the patients seem to predispose the recurrence. Chronic pain was rarely observed in this study.
