Procedures were categorized based on whether or not the attending surgeons possessed JSPS certification as supervisors, and patient characteristics and manipulation time were compared. A multivariate analysis was also performed to evaluate the factors affecting manipulation time.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>In male patients, procedures attended by JSPS-certified supervisory surgeon had a shorter median (IQR) manipulation time (491.5 [396, 626.3] s) than those attended by non-certified surgeons (581 [445.3, 753] s; <jats:italic>P<\/jats:italic>\u2009=\u20090.0092). However, no significant difference was observed in female patients (367 [267.8, 623] vs. 399 [269.5, 593] s; <jats:italic>P<\/jats:italic>\u2009=\u20090.94). A multivariate analysis showed that, in males, attendance by a certified supervisor was associated with shorter manipulation times, whereas a history of hernia incarceration lengthened them. Furthermore, asymptomatic contralateral patent processus vaginalis repair was associated with shorter manipulation times in females.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>Attendance by JSPS-certified supervisory surgeons significantly reduced manipulation time in male SILPEC cases.
