Registry-based comparison of laparoscopic transabdominal preperitoneal and open Lichtenstein repair of inguinal hernia within a standardized day-case surgical pathway
摘要
Laparoscopic transabdominal preperitoneal (TAPP) repair is increasingly used for inguinal hernia treatment. Day-case surgery has become standard in many high-volume centers, but real-world comparative registry data remain limited.
ObjectiveThis study aimed to compare perioperative and 1‑year outcomes of laparoscopic TAPP versus open Lichtenstein repair performed within a standardized day-case surgical pathway.
MethodsThis retrospective analysis of prospectively collected Herniamed registry data included 571 male patients undergoing 635 inguinal hernia repairs between May 2020 and December 2023 at a single high-volume center participating in the Herniamed registry. Patients were treated using either open Lichtenstein repair or laparoscopic TAPP repair within a standardized day-case surgical pathway. Follow-up was conducted at 1 week and 1 year, with a 1-year follow-up rate of 95%. Additional long-term follow-up at 5 and 10 years is ongoing according to the Herniamed registry protocol.
ResultsA total of 635 hernias were analyzed (Lichtenstein: 404; TAPP: 231). Recurrence rates were comparable between groups (3.03% vs. 3.0%; p = 0.98). Early postoperative pain (VAS > 3) at 1 week was significantly lower after TAPP repair (9.5% vs. 17.3%; p = 0.012). At 1 year, chronic discomfort was reported in 5.0% of Lichtenstein and 9.0% of TAPP patients, while pain on exertion was more frequent after Lichtenstein repair (12.0% vs. 4.0%). No major complications occurred in either group.
ConclusionWithin a standardized day-case surgery setting, both TAPP and Lichtenstein repair demonstrated comparable safety and recurrence rates. While long-term outcomes were similar, TAPP was associated with lower pain in the early postoperative period.
