Laparoscopic repair of inguinal hernias with higher risk for recurrence: independent assessment of results from 121 repairs.

This study attempts to determine by independent review the results of laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair for hernias with increased risk for recurrence. Indicators used for increased recurrence risk were recurrent hernias or simultaneously repaired bilateral inguinal hernias. Office and hospital records of all such patients who had undergone TAPP repair were reviewed from one surgeon's 242-patient laparoscopic inguinal hernia database from 1992 to 1998. All were called for assessment by an independent surgeon at least 4 months postoperatively (median 34 months). Those unable to come in person were interviewed by telephone. There were 121 hernias: 34 recurrent and 100 bilateral (13 overlap). Recurrence rate was 3 per cent, which was similar for repair of bilateral and recurrent hernias. All recurrences occurred within 3 months of surgery. No unknown recurrence was detected by the independent observer. Laparoscopic TAPP inguinal hernia repair, often claimed as the method of choice for bilateral and recurrent hernia repair, is indeed a safe and effective procedure with a low early recurrent rate in these higher-risk situations.
