OC-047 LEARNING CURVE IN HERNIA SURGERY- A REGISTER BASED STUDY


 
 
 The purpose of this study was to investigate the learning curve of open anterior mesh repair for groin hernia by assessing hernia recurrence rates, surgical complications, and operative times in relation to the number of procedures performed by surgical trainees.
 
 
 
 Nationwide data on open anterior mesh repair for groin hernia performed by surgical residents were collected from the Swedish Hernia Register between 2005 and 2020. Data were analyzed in a cohort of procedures carried out by surgeons performing their first registered repair as resident. Repairs performed by surgeons who had carried out less than 30 repairs or any repair 1992–2005 were excluded.
 
 
 
 The study group consisted of 38 854 repairs carried out by 663 surgeons. The complication rate increased from 298/9884 (3.0%) the first 15 repairs performed to 396/10978 (3.6%) repairs 31–60 and then decreased to 4/945 (0.4%) for repairs performed after the first 240 ones. Mean operation time decreased from 79 minutes (standard deciation [SD] 26 minutes) the first 15 repairs to 60 minutes (SD 23 minutes) for repairs performed after the first 240 ones. Recurrence rates remained unchanged during the learning curve.
 
 
 
 It is safe for resident surgeons to perform uncomplicated, elective, anterior groin hernia mesh repair after having completed of at least 60 procedures.
