  "abstract": "INTRODUCTION:: Transabdominal preperitoneal (TAPP) repair is an established technique for inguinal hernia repair, but technical complexity and safety concerns during the learning curve may limit its adoption.\n\nAIM:: Our objective was to describe early operative safety and performance of 3 participating surgeons from 3 centers following training in the national “Hernia Master” program.\n\nMATERIALS AND METHODS:: This multicenter retrospective study included 207 patients who underwent 240 elective TAPP groin hernia repairs during 207 sessions, including 33 bilateral procedures. Three trainees contributed 84, 63, and 60 sessions, respectively. Operative time (OT) was assessed using locally weighted scatterplot smoothing (LOWESS) and by comparing chronological halves. Postoperative complications were graded using the Clavien–Dindo classification, whereas intraoperative events and conversions were recorded separately. Surveillance was extended to 3 months, without standardized assessment of recurrence or chronic postoperative inguinal pain.\n\nRESULTS:: Postoperative complications occurred in 5 of 240 repairs (2.1%) and did not differ significantly between phases. Intraoperative adverse events and conversions each occurred in 2 of 240 repairs (0.8%). In the reported analysis of OT, median time decreased for Surgeon 1 (70 vs 55 min; P <0.01). No significant difference was found in the case of Surgeon 2 (110 vs 95 min), whereas Surgeon 3 showed a nonsignificant trend toward shorter OT (75 vs 65 min; P = 0.09). LOWESS curves indicated continued improvement without a clear plateau.\n\nCONCLUSIONS:: This selected 3-surgeon cohort demonstrates early safety and operative performance following structured training. The findings cannot establish the effectiveness of the program as a whole, a threshold for proficiency, or long-term treatment quality. Prospective evaluation of all trainees, with standardized assessments of recurrence and chronic postoperative inguinal pain, is needed.",
