However, it is essential to maintain patient safety and outcomes during the learning process. In Japan, the endoscopic surgical skill qualification (ESSQ) system in pediatric surgery was initiated by the Japan Society for Endoscopic Surgery (JSES) in 2009 to objectively evaluate the skill of endoscopic surgeons. This study compared perioperative outcomes between pediatric surgeons with ESSQ qualifications and those without (non-ESSQ).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>We retrospectively reviewed the medical records of children with choledochal cyst (CC), lobectomy, and biliary atresia (BA) who underwent MIS at our hospital from 2013 to 2023.

For the CC and lobectomy groups, there were no significant differences in operating time, blood loss, and postoperative complications (PO) between the ESSQ and non-ESSQ groups. In BA, the operative times for the ESSQ and non-ESSQ groups were 310 and 377\u00a0min, respectively (<jats:italic>p<\/jats:italic>\u2009=\u20090.001).
