    Abstract:
    INTRODUCTION: Although T-LESS is increasingly being used to treat pediatric inguinal hernia, there is no study regarding T-LESS for pediatric hydrocele. OBJECTIVE: To further evaluate the feasibility of T-LESS and present our single-center experience for repair of pediatric hydroceles. STUDY DESIGN: From January 2016 to July 2016, all boys undergoing T-LESS for hydrocele in our institute were retrospectively reviewed. A laparoscope and a needle-holding forceps were introduced at umbilicus. A round needle with silk suture was stabbed through the abdominal wall. The peritoneum around the internal ring was sutured continuously in a clockwise direction. After a complete purse-string suture, a triple knot was performed by using a single-instrument tie technique. The contralateral patent processus vaginalis (PPV) was repaired simultaneously if present. RESULTS: Overall, 59 boys with hydrocele were included (22 on the left side, 32 on the right side, and 5 bilaterally) (Table). During the procedure, all hydroceles were observed with a PPV but the fluid needed to be aspired in 39 boys. A contralateral PPV was present in 24 boys with unilateral hydrocele, and finally 88 repairs were performed. Mean operative time was 18.3 min for unilateral repair and 27.5 min for bilateral repair, respectively. All procedures were uneventful besides a minor injury to the inferior epigastric vessels. After a mean follow-up of 10.7 months, neither recurrence nor other postoperative complication was observed. There were no visible scars on the abdominal wall. DISCUSSION: Compared with open repair of pediatric inguinal hernia and hydrocele, laparoscopic surgery had several advantages, such as exploration of contralateral PPV, identification of rare hernias, diminished postoperative pain, improved cosmesis, faster recovery, and fewer complications. Differing from the laparoscopic retroperitoneal approach, T-LESS included no subcutaneous tissue in the ligature, and its knot was completely in the peritoneal cavity which could radically prevent the severe pain and suture granuloma in the ligated region. Furthermore, the skin incisions after T-LESS were hidden in umbilicus, which could achieve an excellent cosmetic result. By performing T-LESS for pediatric hydroceles, the current study showed very satisfactory results, such as high success rate, minor complication, and excellent cosmesis. However, because of the difficult learning curve of T-LESS, some technical details (e.g. avoiding injury to the spermatic cord, completely suturing the peritoneal folds and reducing disturbance between the instruments) still need to be improved in the future. CONCLUSION: T-LESS appears to be a safe and effective method for repair of pediatric hydroceles.
