Hernia repair surgery is common, especially the Shouldice repair for primary inguinal hernias, which is considered a top-notch nonmesh technique. However, outcomes can vary, possibly due to differences in surgical skill and experience. Many surgeons are trained more in mesh repairs like the Lichtenstein technique, rather than nonmesh repairs like Shouldice. Understanding a surgeon's learning curve-how many surgeries they need to do to become proficient-is crucial. Yet, there's not much research on this for the Shouldice repair. This project aims to fill that gap and improve surgeon education. The study's goal is to find out how the learning curve affects Shouldice repair for primary inguinal hernias. They'll look at how operative time changes over a surgeon's first 300 repairs compared to their 900-1000th. They'll also check for complications and recurrence rates. The study objectives are: 1. Explore the learning curve and factors affecting Shouldice repair. 2. Compare operative times between a surgeon's early and later surgeries. 3. Look at complications during the learning curve. 4. Determine how long training takes at Shouldice Hospital and the surgeons' previous experience. 5. Review recurrence rates between the first 300 and 900-1000 surgeries. This research aims to give surgeons and the hernia community valuable insights into improving surgical techniques and patient outcomes.
