While non-absorbable sutures are traditionally preferred to minimize recurrence, they pose potential long-term risks as permanent foreign bodies, including suture reaction and theoretical oncogenic concerns. Recent expert consensus suggests absorbable sutures may be a viable alternative, though comparative evidence, particularly for slow-absorbable variants, is limited.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>This study aimed to compare the surgical outcomes, specifically recurrence rates and suture-related complications, between slow-absorbable (Polydioxanone, PDS) and non-absorbable (MERSILK) sutures in single-port laparoscopic indirect inguinal hernia repair in children.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A retrospective analysis was conducted on 1022 children with unilateral indirect inguinal hernia who underwent surgery at our center between October 2022 and October 2023. Patients were divided into two groups based on the suture material used: a slow-absorbable suture group (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009663) and a non-absorbable suture group (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u2009359). Patient demographics, operative details, and postoperative complications (recurrence and suture knot reaction) were compared.
