Abstract
INTRODUCTION: Abdominoscrotal hydrocele (ASH), a composite of scrotal and abdominal hydroceles connected through the inguinal canal, is rare and no consensus regarding its mechanisms and surgical treatments has been reached to date. PRESENTATION OF THE CASE: We report a case of an 11-month-old boy with a large ASH. Ultrasonography and magnetic resonance imaging (MRI) revealed a huge hydrocele (maximum length: 8 cm). The patient underwent laparoscopic percutaneous extraperitoneal closure (LPEC) and the orifice of the processus vaginalis (PV) was completely closed. The postoperative course was uneventful. Follow-up ultrasonography and MRI in the first postoperative year showed no recurrence of ASH. DISCUSSION: An ASH with a length >8 cm is considered rare in pediatric patients. There is no consensus regarding its etiology and surgical intervention is selected according to the patient's condition and the characteristics of ASH. We opted to perform early surgical intervention considering the ASH size and the adverse effects on testicular development. LPEC helped identify the condition and location of the ASH and allowed safe and reliable operation of the large intrapelvic hydrocele. In patients with no PV patency, a change in approach from LPEC to an open anterior approach should be considered even if LPEC is feasible. CONCLUSION: This case provides valuable insight into successful LPEC of a large ASH without any complications, highlighting the importance of elucidating the morphological mechanisms and making an accurate diagnosis and the challenges associated with these processes.
