Outcome of laparoscopic transabdominal preperitoneal inguinal hernia repair

The long-term efficacy of laparoscopic inguinal hernia repair is unknown. This retrospective study was conducted to determine the efficacy of this operation in comparison with the open technique and to evaluate the possible factors of recurrence. We have evaluated the clinical outcome in a group of patients who underwent laparoscopic procedures between January 1995 and December 1996, with the aim of assessing the incidence of recurrence and of long-term complications. Sixty-three patients underwent laparoscopic transabdominal preperitoneal repair by use of a large mesh. We were able to examine 58 of these patients at a median follow-up time of 15 months since their operation. Four patients had developed a recurrence, and two patients had significant symptoms consistent with nerve damage. The recurrence rate of 7% is similar to that reported for open operations but higher than that reported for early follow-up after laparoscopic operations. Our study illustrates the value of long-term follow-up for the assessment of efficacy following laparoscopic inguinal hernia surgery.
