    Abstract:
    Background: Hydrocele of the canal of Nuck (HCN) is a rare cause of inguinal swelling in women. The optimal surgical procedure for HCN in children remains unclear. To assess the safety and efficacy of laparoscopic percutaneous extraperitoneal closure (LPEC) for HCN in a pediatric population, a retrospective study was conducted. In addition, to clarify the pathogenesis of HCN, we assessed the morphological findings of the internal inguinal ring (IIR). Materials and Methods: We retrospectively analyzed 10 consecutive female patients with HCN who underwent LPEC at our hospital between January 2010 and May 2020. Age, operative time, and complications were recorded. Concerning the findings of the IIR, we classified the morphological features as follows: Type 1 (flat), Type 2 (narrow patent processus vaginalis [PPV] with a peritoneal veil), and Type 3 (widely opening PPV). Results: The median age of patients who underwent LPEC was 3 (1-12) years. Although 2 patients showed contralateral inguinal hernia (IH), there were no cases of ipsilateral IH. All patients showed ipsilateral PPV, and the morphological features of the IIR were mostly classified as Type 3 (70%). In total, 6 of 8 HCN cases without preoperatively diagnosed contralateral IH had contralateral PPV (75%), and all were closed by LPEC. All operations were accomplished laparoscopically, and the postoperative course was uncomplicated, with no recurrences observed during the study period. Conclusions: LPEC is a safe and simple surgical approach to repair the HCN in children with minimal complications.
