RESUMEN
PURPOSE: This study aimed to compare techniques and outcomes of robotic-assisted varicocelectomy (RAV) and laparoscopic varicocelectomy (LV). METHODS: The medical records of 40 patients, who received RAV and LV over a 2-year period, were retrospectively analyzed. Palomo lymphatic-sparing varicocelectomy using ICG fluorescence was adopted in all cases. Three 5-mm trocars were placed in LV, whereas four ports, three 8-mm and one 5-mm, were placed in RAV. The spermatic vessels were ligated using clips in LV and ligatures in RAV. The two groups were compared regarding patient baseline and operative outcomes. RESULTS: All patients, with median age of 14 years (range 11-17), had left grade 3 varicocele according to Dubin-Amelar. All were symptomatic and 33/40 (82.5%) presented left testicular hypotrophy. All procedures were completed without conversion. The average operative time was significantly shorter in LV [20 min (range 11-30)] than in RAV [34.5 min (range 30-46)] (p = 0.001). No significant differences regarding analgesic requirement and hospitalization were observed (p = 0.55). At long-term follow-up (30 months), no complications occurred in both groups. The cosmetic outcome was significantly better in LV than RAV at 6-month and 12-month evaluations (p = 0.001). The total cost was significantly lower in LV (1.587,07 ) compared to RAV (5.650,31 ) (p = 0.001). CONCLUSION: RAV can be safely and effectively performed in pediatric patients, with the same excellent outcomes as conventional laparoscopic procedure. Laparoscopy has the advantages of faster surgery, smaller instruments, better cosmesis and lower cost than robotics. To date, laparoscopy remains preferable to robotics to treat pediatric varicocele.

BACKGROUND: Simulation-based training plays a significant role in surgical education, especially in minimally invasive pediatric surgery and urology. This study aimed to evaluate a novel 3D-printed model as training tool for endoscopic injection of bulking agent. METHODS: Forty-three attendees and ten teaching faculty members were invited to complete a post hoc questionnaire after completing training sessions using the Fish Tank Simulation Model (FTSM). The survey consisted of a 7-question 5-point Likert scale to assess the model's realism (face validity) and its effectiveness as training tool (content validity). RESULTS: Regarding the training status, 20/53 (37.7%) participants were fellow and/or specialist in pediatric surgery and 33/53 (62.3%) were surgeons in training. Their level of confidence in endoscopic injection procedure was defined as novice (< 10 procedures per year) in 33/53 (62.3%), intermediate (10-20 procedures per year) in 10/53 (18.9%), and expert (> 20 procedures per year) in 10/53 (18.9%). Regarding both face validity and content validity assessments, no statistically significant differences were found between scores given by novice vs intermediate/expert groups. Similarly, no statistically significant differences emerged between scores given by participant vs faculty groups assessing the content validity of the FTSM. The FTSM was considered a good teaching tool for beginners by 44/53 (83%) and for pediatric surgeons/urologists by 38/53 (71.7%). CONCLUSIONS: The 3D-printed Fish Tank Simulation Model proved to be a valuable, high-fidelity, easily accessible, cost-effective, hygienic, and domestic-use training tool for pediatric surgeons/urologists conducting the procedure. The model's user-friendly design and realistic environment enhanced learning opportunities for trainees, regardless of their experience level or training status. Nevertheless, further development is necessary, particularly in enhancing the realism of the ureteral hiatus and reproducing more complex anatomy, to make it beneficial for the training of advanced surgeons.

BACKGROUND: Anal fistula and perianal abscess are commonly acquired anorectal pathologies in children. Surgical treatment options commonly adopted are fistulotomy, fistulectomy, cutting seton placement, and more recently video-assisted anal fistula treatment (VAAFT). Optimal postoperative wound dressing remains debated. This study aimed to report our series of pediatric patients, who received VAAFT and postoperative wound dressing using ozonide oil. METHODS: All patients who underwent VAAFT between August 2018 and May 2023 were included in the study. Demographics, clinical features, pre-operative imaging, surgical details, outcome, and mid-term outcome data were retrospectively reviewed for each patient. All VAAFT procedures were performed under general anesthesia and using a 10-Ch fistuloscope. RESULTS: Thirty-three VAAFT procedures were performed in 30 patients over the study period. The median patient age was 5.7 years (range 1.75-14). Anal fistula was idiopathic in 26/30 (86.6%), iatrogenic in 2/30 (6.7%), and secondary to Crohn's disease in 2/30 (6.7%). The median duration of surgery was 23 min (range 18-40). All patients received ozonide oil dressing twice a day for 5 weeks postoperatively. The median hospital stay was 24 h (range 9-36). The median healing time was 28 days (range 17-39). With a median follow-up of 2 years (range 0.5-5), disease recurrence occurred in 3/30 (10%) patients with idiopathic fistula, who were re-operated using the same technique, with no further recurrence. No fecal incontinence or soiling was observed. CONCLUSION: Our series confirmed that VAAFT is a safe and effective technique to treat children with perianal fistula. The technique is versatile, allowing to treat fistulae of different etiologies. Postoperative course was painless and fast. Future comparative prospective studies are needed to better establish these conclusions.

INTRODUCTION: Over the years, congenital lung malformations (CLM) management remains a controversial topic in pediatric thoracic surgery. The Italian Society of Pediatric Surgery performed a national survey to study the current management variability among centers, trying to define national guidelines and a standardized approach of children with congenital lung malformations. METHODS: Following a National Society approval, an electronic survey including 35 items on post-natal management was designed, focusing on surgical, anesthesiology, radiology and pneumology aspects. The survey was conducted contacting all pediatric surgical units performing thoracic surgery. RESULTS: 39 pediatric surgery units (97.5%) participated in the study. 13 centers (33.3%) were classified as high-volume (Group A), while 26 centers (66.7%) were low volume (Group B). Variances in diagnostic imaging protocols were observed, with Group A performing fewer CT scans compared to Group B (p = 0.012). Surgical indications favored operative approaches for asymptomatic CLM and pulmonary sequestrations in both groups, while a wait-and-see approach was common for congenital lobar emphysema. Surgical timing for asymptomatic CLM differed significantly, with most high-volume centers operating on patients younger than 12 months (p = 0.02). Thoracoscopy was the preferred approach for asymptomatic CLM in most of centers, while postoperative long-term follow-up was not performed in most of the centers. CONCLUSION: Thoracoscopic approach seems uniform in asymptomatic CLM patients and variable in symptomatic children. Lack of uniformity in surgical timing and preoperative imaging assessment has been identified as key areas to establish a common national pattern of care for CLM.

A 16-year-old girl with down syndrome came to our attention for recurrent postprandial vomiting and significant weight loss (>5 kgs). Diagnostic assessment (barium swallow study, ultrasonography, and CT) confirmed hypertrophic pyloric stenosis (HPS). Initial attempt with endoscopic dilation was not successful. The patient underwent Heineke-Mikulicz pyloroplasty. Full oral feeding was achieved by Day 7 postoperatively. At 6-month follow-up, the patient reported relief of symptoms, normal feeding habits and substantial weight gain. HPS should be considered in the differential diagnosis of recurrent vomiting, regardless of age. A comprehensive diagnostic work-up, including ultrasonography, endoscopy, and CT, is recommended to confirm the diagnosis.
RESUMEN
Testicular cavernous hemangioma is a rare benign vascular tumor that typically occurs in childhood and adolescence. The clinical presentation may be variable and lead to diagnostic difficulties. We report an atypical presentation of intratesticular cavernous hemangioma with acute onset mimicking testicular torsion in a teenager. Inadvertent minor scrotal injury may have probably triggered the rupture of the hemangioma, leading to hemorrhage and infarction of the testicle. Although ultrasonography findings and serum tumor markers may be helpful in differential diagnosis, surgical exploration, and pathology examination are essential for definitive diagnosis.

BACKGROUND: Surgical techniques for treatment of gynecomastia are increasingly less invasive. We described technical standardization of pediatric endoscopic subcutaneous mastectomy (PESMA) with liposuction. METHODS: All adolescents with primary gynecomastia, operated using PESMA with liposuction over the period June 2014-July 2021, were included. The video recording of procedures was analyzed to standardize the operative technique. After patient installation, 3 trocars were placed on the mid-axillary line. The technique included 5 steps: (1) subcutaneous injection of lipolysis solution and liposuction; (2) creation of working space using an inflated balloon; (3) gland dissection using 5-mm sealing device; (4) specimen extraction through the largest trocar orifice; and (5) placement of suction drainage tube. RESULTS: Twenty-four male adolescents, operated for Simon's grade 2B and 3 gynecomastia using PESMA with liposuction over the study period, were included. Mean patient age was 16 years (range 15-18). Gynecomastia was bilateral in 19/24 (79.2%) and unilateral in 5/24 (20.8%). One (4.1%) conversion to open was reported. The mean operative time was 87 min (range 98-160) for unilateral and 160 min (range 140-250) for bilateral procedure. The mean length of stay was 2.2 days (range 1-4). Patients wore a thoracic belt for 15 up to 30 days postoperatively. Post-operative complications occurred in 5/24 (20.8%): 2- or 3 mm second-degree burns in 4 (16.7%) and subcutaneous seroma in 1 (4.1%). All complications were Clavien 2 grade and did not require further treatment. Aesthetic outcomes were very good in 21/24 (87.5%). Three (12.5%) boys had persistent minimal breast asymmetry but did never perceive it negatively. CONCLUSION: PESMA combined with liposuction was feasible and safe for surgical treatment of gynecomastia in this selected cohort of patients. Although challenging, this procedure provided good aesthetic results, with no scars on the anterior thoracic wall. Standardization of the operative technique was a key point for successful outcome.

Quality of life (QOL) outcome is an ideal method for determining the efficacy of a surgical treatment. In children operated for pilonidal sinus disease (PSD), open procedures imply prolonged wound care, significant morbidity, and high recurrence rates. Endoscopic treatment (PEPSIT) overcomes these limitations. We report our experience in the management of PSD to evaluate the QOL of patients undergoing open and endoscopic treatment. The records of 177 patients undergoing surgery for PSD from 2008 to 2021 were retrospectively reviewed. Twenty patients were operated with open surgery (G1) and 157 with PEPSIT (G2). We analyzed QOL through the following criteria: hospital stay (HS), healing time (HT), return to sport (RTSp), return to school (RTSc), resumption of social life (RSL), and recurrence rate and reoperation (RRR). Moreover, we used Pediatric Quality of Life Enjoyment and Satisfaction Questionnaire (PQ-LES-Q) for a more subjective evaluation of life satisfaction. We found significant differences in all the analyzed criteria: HS varied from 3 to 7 days in G1 and from 1 to 2 days in G2; HT from 40 to 75 days in G1 while from 20 to 41 days in G2; RTSp from 50 to 80 days in G1 while from 7 to 21 days in G2; RTSc from 9 to 15 days in G1 while from 2 to 4 days in G2; RSL from 13 to 20 days in G1 while from 2 to 5 days in G2; RRR was 25% in G1 and 4.4% in G2. CONCLUSION: Endoscopic treatment (PEPSIT) significantly improves the quality of life of patients operated for PSD. Compared to open surgery, PEPSIT presents shorter hospital stay, faster healing time, return to sport activities, return to school and resumption of a normal social life, and lower rates of recurrence and reoperation. In addition, PQ-LES-Q demonstrated a good overall quality of life and life satisfaction. Further prospective studies should be obtained to consider PEPSIT as the gold standard for the treatment of PSD in pediatric patients. WHAT IS KNOWN: ⢠Many techniques have been proposed in the last 20 years for the surgical treatment of PSD. ⢠PEPSIT is showing promising results in terms of safety and long-term efficacy. WHAT IS NEW: ⢠The main impact in QOL of patients operated with PEPSIT is on their daily activity, including a shorter hospital stay, faster healing time, return to sport activities, return to school and resumption of a normal social life, lower rates of recurrence and reoperation. ⢠After PEPSIT, children maintain a satisfactory quality of life according to the analysis of PQ-LES-Q.

In the last 20 years, endoscopic injection (EI) has affirmed as a valid alternative to open surgery for management of pediatric vesicoureteral reflux (VUR). This study aimed to investigate and discuss some debated aspects such as indications, bulking agents and comparison, techniques of injection and comparison, predictive factors of success, use in specific situations. EI is minimally invasive, well accepted by patients and families, with short learning curve and low-morbidity profile. It provides reflux resolution rates approaching those of open reimplantation, ranging from 69 to 100%. Obviously, the success rate may be influenced by several factors. Recently, it is adopted as first-line therapy also in high grade reflux or complex anatomy such as duplex, bladder diverticula, ectopic ureters. The two most used materials for injection are Deflux and Vantris. The first is absorbable, easier to inject, has lower risk of obstruction, but can lose efficacy over time. The second is non-absorbable, more difficult to inject, has higher risk of obstruction, but it is potentially more durable. The two main techniques are STING and HIT. To date, the ideal material and technique of injection has not yet clearly established, but the choice remains dependent on surgeon's preference and experience.

PURPOSE: Our goal was to compare surgical scars assessed by a validated patient reported outcome questionnaire in children undergoing open (OP), laparoscopic (LP), or robotic-assisted (RALP) pyeloplasty. Our secondary aim was to assess the influence on the outcomes of variables such as gender or body mass index (BMI). MATERIALS AND METHODS: We conducted an observational, cross-sectional, multicentric study of patients undergoing primary pyeloplasty between age 10 and 18 years at 5 tertiary Italian institutions during the period January 2010 to December 2019. Of 227 eligible patients 114 (50%) participated. OP was performed in 37 (32%), LP in 30 (26%) and RALP in 47 (41%), After a median (IQR) followup of 5.2 (2.3-7.8) years, scars were measured and assessed by a validated Patient Scar Assessment Questionnaire. Scores were compared among techniques and in accordance with several variables. RESULTS: The median length of the surgical scar at followup was significantly larger (p <0.0001) after OP (8.1 cm vs 1.8 cm for LP and 2.0 cm for RALP), where scar length correlated with BMI (p=0.04). Ninety patients (79%) had a Patient Scar Assessment Questionnaire score within the first quartile, the most favorable. During followup, 43 (38%) participants reported scar-related symptom. Symptoms were generally more common after OP (54% vs 30% for LP and 30% for RALP, p=0.06) and scar hyperesthesia was significantly more frequent after OP (p=0.01). CONCLUSIONS: Perception of the cosmetic outcomes in pre-adolescents and adolescents after pyeloplasty was generally good. LP achieved the best cosmetic results. OP was more commonly associated with scar-related symptoms and the size of the incision paralleled BMI.

BACKGROUND: In the last few years, indocyanine green (ICG) fluorescent cholangiography (FC) has been adopted to perform intra-operative biliary mapping during laparoscopic cholecystectomy (LC). This study aimed to compare the results of LC with and without use of ICG-FC. METHODS: All LC operated from June 2017 to June 2021 in our unit were retrospectively reviewed. Pre-operative workup included ultrasonography to assess dilation of main biliary tree. The ICG dosage was 0.35 mg/kg and the median timing of administration was 15.5 h pre-operatively. We evaluated, analyzing videorecorded procedures, 3 parameters in both groups: the total operative time (T1), the time of cystic duct isolation, clipping and sectioning (T2), and the time of gallbladder removal from hepatic fossa (T3). RESULTS: Forty-three LC were operated in the study period: 22 using standard technique (G1) and 21 using ICG-FC (G2). There were 27 girls and 16 boys, with median age at surgery of 11.5 years (range 7-17) and median weight of 47 kg (range 31-110). No conversions were reported in our series. In all ICG cases (except one patient under therapy with phenobarbital) the biliary tree was perfectly visualized during dissection. Intra-operative complications occurred in 3 G1 patients (13.6%): 2 bleedings from the Calot's triangle and 1 bleeding from the liver bed during the gallbladder removal. LC was significantly faster in G2 than in G1 (p = 0.001). In fact, the parameters analyzed (T1, T2, T3) were all significantly greater in G1 than in G2 (p = 0.001). CONCLUSIONS: Based upon our experience, we strongly recommend the use of ICG-FC in all pediatric patients undergoing LC. ICG-guided fluorescence provided an excellent real-time visualization of the extrahepatic biliary tree and allowed faster and safer dissection, minimizing the risk of bile duct injuries. Furthermore, ICG use was clinically safe, with no adverse reactions to the product.

PURPOSE: This study aimed to report a multi-institutional retrospective case series of outcomes after robot-assisted laparoscopic pyeloplasty (RALP) in pediatric patients with complex pelvi-ureteric junction obstruction (PUJO). METHODS: All patients undergoing complex RALP over the last 5 years were included. RALP was defined complex in the following cases of PUJO: anatomic variations including ectopic, malrotated, horseshoe, or duplex kidney and recurrent PUJO after failed open pyeloplasty. RESULTS: Forty-eight patients underwent complex RALP in four European centers in the study period and included 18 girls and 30 boys with a median age of 8 years (range 5-12). The PUJO was associated with anatomic variations in 35/48 (72.9%), whereas a recurrent PUJO was present in 13/48 (27.1%). A dismembered Anderson-Hynes pyeloplasty was performed in all patients. The median operative time including docking was 178.5 min (range 117-255) and the median anastomotic time was 64.8 min (range 50-76). All patients were discharged on 2nd postoperative day (POD). The median follow-up was 18.2 months (range 14-43). The overall success rate was 95.8% (46/48). Early postoperative complications (< 30th POD) included urinary tract infections (UTIs) and stent-related irritative symptoms in 4/48 (8.3%) [II Clavien], whereas late complications (> 30th POD) included recurrence of PUJO in 2/48 (4.2%), who needed re-operation [IIIb Clavien]. CONCLUSIONS: RALP was safe, feasible, and with good mid-term outcome in complex PUJO. An accurate pre-operative planning, a standardized technique, and an experienced surgical robotic team represented key points to manage successfully such complex cases.

PURPOSE: This study aimed to standardize the operative technique of indocyanine green (ICG) near-infrared fluorescence (NIRF) laparoscopic partial nephrectomy (LPN) and compare it with the standard technique. METHODS: In the last 4 years, we performed 22 LPN (14 right-sided, 8 left-sided) in children with non-functioning moiety of duplex kidney. Patients included 12 girls and 10 boys with a median age of 3.9 years (range 1-10). Patients were grouped according to the use of ICG-NIRF: G1 included 12 patients operated using ICG-NIRF and G2 included 10 patients receiving the standard technique. We standardized the technique of injection of ICG in three different steps. RESULTS: The median operative time was significantly lower in G1 [87 min (range 68-110)] compared with G2 [140 min (range 70-220)] (p = 0.001). One intra-operative complication occurred in G2. At post-operative ultrasound (US), the residual moiety was normal in all patients. An asymptomatic renal cyst related to the site of surgery was visualized at US in 8/22 (36%), with a significantly higher incidence in G2 (6/10, 60%) compared with G1 (2/12, 16.6%) (p = 0.001). Renogram demonstrated no loss of function of residual moiety. No allergic reactions to ICG occurred. CONCLUSION: ICG-NIRF LPN is technically easier, quicker, and safer compared with the standard technique. The main advantages of using ICG-NIRF during LPN are the clear identification of normal ureter, vasculature of non-functioning pole, and demarcation line between the avascular and the perfused pole. The main limitation of ICG technology remains the need for specific laparoscopic equipment that is not always available.

PURPOSE: This study aimed to evaluate the efficacy of oxygen-enriched oil-based gel dressing on wound healing and postoperative outcome in children who underwent distal hypospadias repair. METHODS: We included all patients with distal hypospadias, who underwent Snodgrass urethroplasty and preputioplasty over an 18-months period. The patients were randomized in two groups according to the type of medication: oxygen-enriched oil-based gel (G1) and hyaluronic acid cream (G2). After discharge, parents changed the dressing twice a day for 2-3 weeks postoperatively. The patients were evaluated at 7, 14, 21, 30, 60 and 180 postoperative days and thereafter annually. RESULTS: One-hundred and fourteen patients (median age 18 months) were included in the study and randomized in two groups, each of 57 patients. The wound healing was significantly faster in G1 compared with G2 (p = 0.001). G1 reported significantly higher SWAS and modified HOPE scores compared with G2 (p = 0.001) at all steps of follow-up. No adverse skin reactions occurred. Foreskin dehiscence and re-operations rates were significantly lower in G1 compared with G2 (p = 0.001). Postoperative foreskin retractability was better in G1, with a significantly higher incidence of secondary phimosis in G2 (p = 0.001). The median treatment costs were significantly lower in G1 compared with G2 (p = 0.001). CONCLUSION: Postoperative dressing using oxygen-enriched oil-based gel was highly effective, promoting a faster wound healing in patients who underwent distal hypospadias repair. It reported a lower incidence of foreskin dehiscence and better foreskin retractability compared with the control group. It was cost-effective and clinically safe without allergy or intolerance to the product.

BACKGROUND: Recently, we reported the feasibility of indocyanine green (ICG) near-infrared fluorescence (NIRF) imaging to identify extrahepatic biliary anatomy during laparoscopic cholecystectomy (LC) in pediatric patients. This paper aimed to describe the use of a new technology, RUBINA™, to perform intra-operative ICG fluorescent cholangiography (FC) in pediatric LC. METHODS: During the last year, ICG-FC was performed during LC using the new technology RUBINA™ in two pediatric surgery units. The ICG dosage was 0.35 mg/Kg and the median timing of administration was 15.6 h prior to surgery. Patient baseline, intra-operative details, rate of biliary anatomy identification, utilization ease, and surgical outcomes were assessed. RESULTS: Thirteen patients (11 girls), with median age at surgery of 12.9 years, underwent LC using the new RUBINA™ technology. Six patients (46.1%) had associated comorbidities and five (38.5%) were practicing drug therapy. Pre-operative workup included ultrasound (n = 13) and cholangio-MRI (n = 5), excluding biliary and/or vascular anatomical anomalies. One patient needed conversion to open surgery and was excluded from the study. The median operative time was 96.9 min (range 55-180). Technical failure of intra-operative ICG-NIRF visualization occurred in 2/12 patients (16.7%). In the other cases, ICG-NIRF allowed to identify biliary/vascular anatomic anomalies in 4/12 (33.3%), including Moynihan's hump of the right hepatic artery (n = 1), supravescicular bile duct (n = 1), and short cystic duct (n = 2). No allergic or adverse reactions to ICG, post-operative complications, or reoperations were reported. CONCLUSION: Our preliminary experience suggested that the new RUBINA™ technology was very effective to perform ICG-FC during LC in pediatric patients. The advantages of this technology include the possibility to overlay the ICG-NIRF data onto the standard white light image and provide surgeons a constant fluorescence imaging of the target anatomy to assess position of critical biliary structures or presence of anatomical anomalies and safely perform the operation.

BACKGROUND AND OBJECTIVE: Pediatric endoscopic pilonidal sinus treatment (PEPSiT) has become the new standard of care for pilonidal sinus disease (PSD) in pediatric patients. This study aimed to compare our current wound treatment protocol (laser epilation (LE) and oxygen-enriched oil-based gel dressing) with our previous protocol (silver sulfadiazine spray) and demonstrate its efficacy as means to prevent PSD recurrence in children undergoing PEPSiT. STUDY DESIGN/MATERIALS AND METHODS: We retrospectively reviewed the data of 87 pediatric patients, 52 boys and 35 girls, with an average age of 17.1 years (range, 12-18) affected by chronic PSD, who underwent PEPSiT over a 24-month period (December 2017-December 2019). The patients were divided into two groups: G1 (n = 47) treated with pre- and postoperative LE and oxygen-enriched oil-based gel dressing; and G2 (n = 40) treated with only postoperative dressing using silver sulfadiazine spray. The two groups were compared regarding the operative outcome, wound-healing time, disease recurrence, wound infections, and other complications. Furthermore, efficacy, safety, and tolerability of LE were assessed in G1. RESULTS: No significant difference emerged between the two groups regarding the median operating time, postoperative pain score, hospital stay length, and time to full daily activities (P = 0.33). The median healing time significantly decreased in G1 (21 days) compared with G2 (28.1 days) (P = 0.001]. The disease recurrence rate was significantly lower in G1 (n = 1, 2.1%) compared with G2 (n = 6, 15%) (P = 0.001), and the wound infection rate was significantly lower in G1 (n = 1, 2.1%) compared with G2 (n = 4, 10%) (P = 0.001). All patients with wound infection were treated with oral antibiotics and, after the resolution of the acute episode, received LE with no further infections (Clavien II). Granuloma of the wound occurred in two G2 patients (5%), who were treated with topical silver nitrate (Clavien II). LE was well-tolerated and without complications in all G1 patients; a median number of 7 LE sessions (range, 4-10) at 4-6 weeks interval was required to achieve definitive hair removal. CONCLUSION: The results of this study confirmed that our standardized pre- and postoperative wound management, including LE and oxygen-enriched oil-based gel dressing, was extremely safe and effective in reducing PSD recurrence and wound infection rate in pediatric patients undergoing PEPSiT. LE should be routinely offered as adjunctive treatment to all patients who receive PEPSiT and is strongly advocated to be started before surgery and continued after wound healing. More importantly, LE showed to have a role as a preventive modality in patients with recurrent folliculitis or infections at the intergluteal crease. It was also associated with significant improvement and acceleration of wound-healing time. LE and oxygen-enriched oil-based gel dressings were clinically safe and well-tolerated in all patients, with no adverse skin reactions or injuries to both therapies. Lasers Surg.

RESUMEN
OBJECTIVES: To assess and compare postoperative bladder dysfunction rates and outcomes after laparoscopic and robot-assisted extravesical ureteric reimplantation in children and to identify risk factors associated with bladder dysfunction. PATIENTS AND METHODS: A total of 151 children underwent minimally invasive extravesical ureteric reimplantation in five international centres of paediatric urology over a 5-year period (January 2013-January 2018). The children were divided in two groups according to surgical approach: group 1 underwent laporoscopic reimplantation and included 116 children (92 girls and 24 boys with a median age of 4.5 years), while group 2 underwent robot-assisted reimplantation and included 35 children (29 girls and six boys with a median age of 7.5 years). The two groups were compared with regard to: procedure length; success rate; postoperative complication rate; and postoperative bladder dysfunction rate (acute urinary retention [AUR] and voiding dysfunction). Univariate and multivariate logistic regression analyses were performed to assess predictors of postoperative bladder dysfunction. Factors assessed included age, gender, laterality, duration of procedure, pre-existing bladder and bowel dysfunction (BBD) and pain control. RESULTS: The mean operating time was significantly longer in group 2 compared with group 1, for both unilateral (159.5 vs 109.5 min) and bilateral procedures (202 vs 132 min; P = 0.001). The success rate was significantly higher in group 2 than in group 1 (100% vs 95.6%; P = 0.001). The overall postoperative bladder dysfunction rate was 8.6% and no significant difference was found between group 1 (6.9%) and group 2 (14.3%; P = 0.17). All AUR cases were managed with short-term bladder catheterization except for two cases (1.3%) in group 1 that required short-term suprapubic catheterization. Univariate and multivariate analyses showed that bilateral pathology, pre-existing BBD and duration of procedure were predictors of postoperative bladder dysfunction (P = 0.001). CONCLUSION: Our results confirmed that short-term bladder dysfunction is a possible complication of extravesical ureteric reimplantation, with no significant difference between the laparoscopic and robot-assisted approaches. Bladder dysfunction occurred more often after bilateral repairs, but required suprapubic catheterization in only 1.3% of cases. Bilaterality, pre-existing BBD and duration of surgery were confirmed on univariate and multivariate analyses as predictors of postoperative bladder dysfunction in this series.

PURPOSE: This multicentric study aimed to report our experience with robot-assisted laparoscopic pyeloplasty (RALP) in children with horseshoe kidney (HSK). METHODS: The records of 14 patients (11 boys and 3 girls with an average age of 9 years), who underwent RALP for repair of pelvi-ureteric junction obstruction (PUJO) in HSK in five international pediatric urology units over a 5-year period, were retrospectively reviewed. A dismembered pyeloplasty with no division of isthmus was performed in all the cases. RESULTS: The average operative time including docking was 143.5 min (range 100-205). No conversions to laparoscopy or open surgery or intra-operative complications occurred. Patients were discharged on postoperative day 2 following catheter and drain removal. The JJ stent was removed at mean 33 days postoperatively. Overall success rate was 92.8%. As for postoperative complications, we recorded a urinary tract infection (UTI) and stent-related irritative symptoms, managed with medical therapy, in two patients (II Clavien) and an anastomotic stricture in one patient needing surgical revision with no further recurrence (IIIb Clavien). At follow-up, all the patients (one after redo-surgery) reported complete resolution of symptoms, improvement of hydronephrosis on ultrasound and no residual obstruction on diuretic renogram. CONCLUSIONS: Our experience suggested that RALP in HSK is safe, feasible and with good medium-term outcomes in expert hands. An accurate pre-operative planning associated with a standardized technique is key points to achieve good surgical and functional outcomes in these challenging cases. The da Vinci robot technology offers the advantages of MIS procedures and overcomes the technical challenges of laparoscopic approach.

PURPOSE: This retrospective study aimed to report a multi-institutional experience with laparoscopic and robotic-assisted repair of retrocaval ureter in children and to compare outcome of minimally invasive surgery (MIS) with open repair. METHODS: The records of all children, who underwent MIS and open repair of retrocaval ureters in six international pediatric urology units over a 5-year period, were retrospectively collected. Data were grouped according to the operative approach: a laparoscopic group (G1) included five patients, a robotic-assisted group (G2) included four patients, and an open group (G3) included three patients. The groups were compared in regard to operative and postoperative outcomes. RESULTS: At follow-up, all patients (one G1 patient after redo-surgery) reported complete resolution of symptoms and radiologic improvement of hydronephrosis and obstruction. In regard to postoperative complications, one G1 patient developed stenosis of anastomosis and needed re-operation with no further recurrence (IIIb Clavien). G2 reported the lowest average operative time (135 min) compared to G1 (178.3 min) and G3 (210 min). MIS (G1-G2) reported a significantly better postoperative outcome compared to open repair (G3) in terms of analgesic requirements, hospitalization, and cosmetic results. CONCLUSIONS: The study outcomes suggest that MIS should be the first choice for retrocaval ureter because of the minimal invasiveness and the better cosmetic outcome compared to open surgery. Furthermore, our results showed that robotic-assisted reconstruction was technically easier, safer, and quicker compared to laparoscopic repair, and for these reasons, it should be preferentially adopted, when available.

BACKGROUND: Very limited informations are currently available about the best approach to perform retroperitoneoscopic surgery. This multicentric international study aimed to compare the outcome of lateral versus prone approach for retroperitoneoscopic partial nephrectomy (RPN) in children. METHODS: The records of 164 patients underwent RPN in 7 international centers of pediatric surgery over the last 5 years were retrospectively reviewed. Sixty-one patients (42 girls and 19 boys, average age 3.8 years) were operated using lateral approach (G1), whereas 103 patients (66 girls and 37 boys, average age 3.0 years) underwent prone RPN (G2). The two groups were compared in regard to operative time, postoperative outcome, postoperative complications, and re-operations. RESULTS: The average operative time was significantly shorter in G2 (99 min) compared to G1 (160 min) (p = 0.001). Only 2 lateral RPN required conversion to open surgery. There was no significant difference between the two groups as for intraoperative complications (G1:2/61, 3.3%; G2:6/103, 5.8%; p = 0.48), postoperative complications (G1:9/61, 14.7%; G2:17/103, 16.5%; p = 0.80), and re-operations (G1:2/61, 3.3%; G2:4/103, 3.8%; p = 0.85). Regarding postoperative complications, the incidence of symptomatic residual distal ureteric stumps (RDUS) was significantly higher in G2 (7/103, 6.8%) compared to G1 (1/61, 1.6%) (p = 0.001). Most re-operations (4/6, 66.6%) were performed to remove a RDUS . CONCLUSIONS: Both lateral and prone approach are feasible and reasonably safe to perform RPN in children but the superiority of one approach over another is not still confirmed. Although prone technique resulted faster compared to lateral approach, the choice of the technique remains dependent on the surgeon's personal preference and experience. Our results would suggest that the lateral approach should be preferred to the prone technique when a longer ureterectomy is required, for example in cases of vesico-ureteral reflux into the affected kidney moiety, in order to avoid to leave a long ureteric stump that could become symptomatic and require a re-intervention.
