As part of training, surgical residents perform these procedures, which raises questions about the safety and efficacy of their involvement compared to specialists. This study compares the postoperative outcome and complications of inguinal hernia repairs conducted by residents under supervision with those performed by board certified surgeons independent of the method of surgery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"j_iss-2025-0028_abs_002\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This retrospective cohort study was performed at a single tertiary care center. 388 patients undergoing inguinal hernia repair, aged 18\u00a0years and older were included.

The hernia repairs were mostly performed as an open procedure by residents (n=72; 45\u202f%), whereas board-certified surgeons mostly operated laparoscopically (n=190; 83\u202f%). Surgical trainees had significantly longer operation times when performing a laparoscopic procedure than attending surgeons (means: 94 vs.70\u202fmin;\n                      <jats:italic>p<\/jats:italic>\n                      &lt;0.001). However, there was no difference in operation time when an open procedure was performed (\n                      <jats:italic>p<\/jats:italic>\n                      =0.988).
