Recently LESS has been reported as a valid minimally option for treatment of some urologic pathologies in pediatrics. However, the initial reports of pediatric LESS are still limited to case reports and initial case series. This may be due to the inherent technical difficulty of LESS and the currently available LESS instruments. In this report, we present the largest case series of pediatric LESS for treatment of different urologic pathologies in pediatrics. Included in this study are children who had LESS during the period of January 2011 to June 2013. Both Olympus TriPort (Olympus, New York, USA and Advance Surgical Concept, Wicklow, Ireland) and Covedien SILS access port (Covedien, Chicopec, Massachusetts, USA) were used and were inserted through the umbilicus. Exclusion criteria included children less than 3 years old, history of previous transperitoneal abdominal surgery, malignant indications, and complex urogenital congenital anomalies. All LESS procedures were done by a single experienced laparoscopist and data were reviewed retrospectively. Twenty-two children had 39 LESS procedures without conversion to conventional laparoscopy or open surgery. No intraoperative or postoperative complications were reported and no extra-port was added in any of the patients. The following table shows the mean age, operative time, hospital stay, VAS as well as the overall mean of different LESS procedures. In all patients the umbilical scar was invisible and all patients and their parents had high wound satisfaction. At a mean follow up of 18.6 ± 6.4 months, all patients with UPJO had successful repair. Our study included 13 boys with undescended testis who were managed in different ways according to the length of spermatic vessels and the size of the testis. One of the arguments against LESS management of undescended testis is that it requires a 2.5-cm incision, which is collectively larger than a 5-mm camera and two 3-mm working ports of conventional laparoscopy. However, the Triport access can be inserted through a 12-15-mm single umbilical incision without any additional openings in the abdomen as required with conventional laparoscopy which may increase the risk of internal organ injury and other port-related complications. Our results of five LESS varicocelectomies correlate with reports in the literature; regarding the operative time and hospital stay. LESS pediatric nephrectomy has been reported by many authors and our results correlates with that have been published. Compared with conventional laparoscopic nephrectomy, LESS nephrectomy seems to have shorter operative time and hospital stay. Although both cases of LESS nephrectomy were on the right side, we did not add any extra-ports which could be related to technical modifications during the surgery as well as the experience of the surgeon. To date, few data are available about LESS pyeloplasty in pediatrics. Our study included three patients who had left LESS pyeloplasties. In these patients, no extra-port was added. Despite of the technical difficulty of intracorporeal suturing during LESS, LESS pyeloplasty seems to be feasible with adequate training. Our patients had short hospital stay, low VAS at discharge, received a low dose of NSAID as postoperative analgesic and in all cases there was high wound satisfaction. One of the limitations of the current study could be the selection criteria of the patients, with children younger than 3 years and children who may be more technically difficult, being excluded. Furthermore, the number of patients in some indications is small and more patients are required to give solid conclusions and detect possible complications. Our study demonstrates the technical feasibility and safety of LESS for both ablative and reconstructive pathologies in pediatrics. However, more applications including a larger scale of pediatric patients as well as prospective comparative studies with conventional laparoscopy, are necessary.
