Long-term Outcome of Laparoscopic Hernia Sac Transection and Intracorporeal Ligation in Children: A Single Center Cohort Study

복강 내 탈장낭 절개 및 봉합법을 이용한 소아 복강경 서혜부 탈장 수술의 장기 추적관찰 결과: 단일기관 코호트 연구

Purpose: Laparoscopic hernia repair in children is still controversial. The aim of this study was to report our long-term results of the laparoscopic hernia technique, which is based on the same surgical principles as conventional open herniotomy. Methods: Five hundred fourteen pediatric patients with inguinal hernia were included in this study under informed consent. All patients underwent a laparoscopic technique of sac transection and intracorporeal ligation. The asymptomatic contralateral inguinal ring was routinely explored and repaired if a patient had patent processus vaginalis on the contralateral side. Patients were prospectively followed for 5 years. Those who were lost to follow-up were excluded from the study. Perioperative complications and recurrences were evaluated. Results: The mean follow-up period was 29 months. Mean operation time was 27.5 minutes. Forty one percent of the patients had contralateral patent processus vaginalis. Only one hernia recurred (0.19%). We had one case of contralateral metachronous hernia (0.21%) during follow-up period. Conclusion: The long-term follow-up results of our study revealed that laparoscopic hernia sac transection and ligation can be a safe and effective alternative for conventional herniorraphy.
