Abstract: Purpose: This study compared the long-term recurrence rates of laparoscopic totally extraperitoneal (TEP) and open inguinal hernia repair in patients from a randomised trial completed in 1994. Laparoscopic inguinal hernia surgery, especially TEP repair, has gained widespread acceptance in recent years. There is still paucity of data on long-term follow-up comparing recurrence rates for open and laparoscopic techniques. This is the first study providing direct long-term comparative data about these techniques. Methods: A randomised controlled trial was conducted between 1992 and 1994 on patients undergoing a laparoscopic TEP or an open inguinal hernia (Shouldice) repair at our institution. Of the original 104 participants, contemporary follow-up data could be obtained for 98 patients with regards to long-term recurrence. These data were collected with the help of questionnaires, telephone calls and retrieval of case records. Medical records were reviewed for all patients. Data were analysed using a Cox proportional hazards model. Results: There were 7/72 (9.7%) recurrences in the open group and 9/35 (25.7%) recurrences in the laparoscopic group. This difference in recurrence rates was statistically significant (HR = 2.94; 95% CI 1.05-8.25; p = 0.041.) Conclusion: Laparoscopic TEP inguinal hernia repair performed in 1992-1994 had a higher recurrence rate than open Shouldice inguinal hernia repair during the same period. The original study was undertaken in the inceptive days of laparoscopic surgery and results need to be interpreted considering the technology and expertise available at that time.
