In addition, 6054 PIH repairs were performed using two-port laparoscopic intracorporeal suturing (TPLIS) at the Capital Center for Children\u2019s Health, Capital Medical University between January 2015 and December 2020.

Both SPLPEC and TPLIS demonstrated low recurrence rates, particularly among females and the second operation proved to be an effective treatment option for recurrent cases. For SPLPEC in obese children, secure ligation of the hernia internal ring is essential to prevent recurrence. TPLIS requires extended follow-up to detect possible late recurrence.<\/jats:p>\n
