ABSTRACT
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.

OBJECTIVES: The present study aimed to assess long-term functional outcomes of children with anorectal malformations (ARMs) across a network of expert centers in France. METHODS: Retrospective cross-sectional study of patients ages 6-30âyears that had been surgically treated for ARM. Patient and ARM characteristics (eg, level, surgical approach) and functional outcomes were assessed in the different age groups. RESULTS: Among 367 patients, there were 155 females (42.2%) and 212 males (57.8%), 188 (51.2%) cases with, and 179 (48.8%) higher forms without, perineal fistula. Univariate and multivariate statistical analyses with logistic regression showed correlation between the level of the rectal blind pouch and voluntary bowel movements (odds ratio [OR]â=â1.84 [1.31-2.57], Pâ<â0.001), or soiling (ORâ=â1.72 [1.31-2.25], Pâ<â0.001), which was also associated with the inability to discriminate between stool and gas (ORâ=â2.45 [1.28-4.67], Pâ=â0.007) and the presence of constipation (ORâ=â2.97 [1.74-5.08], Pâ<â0.001). Risk factors for constipation were sacral abnormalities [ORâ=â2.26 [1.23-4.25], Pâ=â0.01) and surgical procedures without an abdominal approach (ORâ=â2.98 [1.29-6.87], Pâ=â0.01). Only the holding of voluntary bowel movements and soiling rates improved with age. CONCLUSION: This cross-sectional study confirms a strong association between anatomical status and functional outcomes in patients surgically treated for ARM. It specifically highlights the need for long-term follow-up of all patients to help them with supportive care.

BACKGROUND: Malignant and multicystic peritoneal mesotheliomas are extremely rare tumors in children, developing from mesothelial cells. No specific guidelines are available at this age. METHODS: We performed a retrospective analysis of all identified children (< 18-year-old) treated in France from 1987 to 2017 for a diffuse malignant peritoneal mesothelioma (DMPM) or a multicystic peritoneal mesothelioma (MCPM). RESULTS: Fourteen patients (5 males and nine females), aged 2.2 to 17.5 years, were included. The most frequent presenting symptoms were abdominal pain, ascitis, and alteration in the general condition. Eight patients had epithelioid mesothelioma, three had biphasic mesothelioma, and three had MCPM. Eight patients with DMPM diagnosis received cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC). Among them, six patients had neoadjuvant systemic chemotherapy, one patient, post-operative chemotherapy, and one patient CRS and HIPEC only. Three patients received only systemic chemotherapy. All patients with MCPM had only surgery. After a median follow-up of seven years (2-15), six patients (6/11; one death) with DMPM and two patients (two/three) with MCPM had a local and distant recurrences. CONCLUSION: Peritoneal mesothelioma in children is a rare condition with difficult diagnosis and high risk of recurrence. Worldwide interdisciplinary collaboration and networking are mandatory to help diagnosis and provide harmonious treatment guidelines.

PURPOSE: To evaluate feasibility and outcomes of minimally invasive surgery (MIS) in Wilms tumor (WT). METHODS: International multicenter review of MIS total nephrectomies for WT between 2006 and 2018. Medical records of confirmed WT were retrospectively assessed for demographic, imaging, treatment, pathology, and oncological outcome data. RESULTS: Fifty patients, with a median age of 38 months (6-181), were included in 10 centers. All patients received neoadjuvant chemotherapy, as per SIOP protocol. Median tumor volume post-chemotherapy was 673 mL (18-3331), 16 tumors crossed the lateral border of the spine, and three crossed the midline. Six patients with tumors that crossed the lateral border of the spine (tumor volumes 1560 mL [299-2480]) were converted to an open approach. There was no intraoperative tumor rupture. Overall, MIS was completed in 19% of the 195 nephrectomies for WT presenting during the study period. Tumor was stage I in 29, II in 16, and III in 5, and histology was reported as low in three, intermediate in 42, and high risk in five. Three patients had positive tumor margins. After a median follow-up of 34 months (2-138), there were two local recurrences (both stage I, intermediate risk, 7 and 9 months after surgery) and one metastatic relapse (stage III, high risk, four months after surgery). The three-year event-free survival was 94%. CONCLUSION: MIS is feasible in 20% of WT, with oncological outcomes comparable with open surgery, no intraoperative rupture, and a low rate of local relapse. Ongoing surveillance is, however, needed to evaluate this technique as it becomes widespread.

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.

BACKGROUND: Retroperitoneoscopic upper pole heminephrectomy (RUHN) in duplex kidney in children remains a challenging procedure with a need for postoperative functional assessment of the remnant lower pole. We aimed to calculate the incidence of long-term functional renal outcomes in these children and examine the effect of age on those outcomes. METHODS: A multicenter retrospective cohort study of 9 years included all patients undergoing RUHN and evaluated by renal ultrasound (US) and dimercaptosuccinic acid (DMSA) scintigraphy pre and postoperatively. Patients were divided in two age groups of ≤12 and >12 months. Standard follow-up assessed pre-, intra- and postoperative outcomes using clinical review, US and DMSA. RESULTS: Standard RUHN in lateral position was performed in 30 patients. Five cases were excluded (2 lacks of postoperative DMSA, 3 conversions). Indications for RUHN were non-functioning upper moieties (n = 25) caused by ureterocele (n = 11), ectopic distal implantation of the ureter with incontinence (n = 6) or evolving severe ureterohydronephrosis (n = 8). Mean age at surgery was 30 ± 27 months, operation time 116 ± 52 min and hospital stay 2.8 ± 1 days. Long-term follow-up (mean, 7.2 ± 2.7 years) with US and DMSA showed that none of the 25 patients had complete loss of lower pole renal function. Mean lower pole renal function directly related to RUHN was not significantly different after versus before RUHN for the entire cohort (n = 24; 39.7 ± 7.90 % vs. 41.7 ± 6.74 %; p = 0350), for the ≤12-month (n = 6; 39.3 ± 4.18 vs. 41.3 ± 5.47; p = 0.493) and the >12-month groups (n = 18; 39.8 ± 8.90 vs. 41.9 ± 7.25; p = 0.443). Four patients (17 %) had partial loss of function (mean function loss, 9.3 ± 5.85 %; median age, 13 months). The number and type of complications between the two age groups were not statistically different. Overall, 29 % (n = 7/24) of the patients presented with medium-term (17 %) and long-term (17 %) complications directly related to RUHN. CONCLUSIONS: RUHN is a demanding yet efficient technique that is safe for the lower pole at any age. Systematic postoperative DMSA is not mandatory as long as US remains normal.

BACKGROUND: This study aimed to standardize the surgical correction technique of congenital Morgagni diaphragmatic hernia (CMDH), analyzing the results of an international multicentric survey. METHODS: The medical records of 43 patients (29 boys, 14 girls) who underwent laparoscopic repair of CMDH in 8 pediatric surgery units in a 5-year period were retrospectively reviewed. Their average age was 3.3 years. Ten patients (23.2%) presented associated malformations: 9 Down syndrome (20.9%) and 1 palate cleft (2.3%). Thirty-five patients (81.4%) were asymptomatic, whereas 8 patients (18.6%) presented symptoms such as respiratory distress, cough or abdominal pain. As for preoperative work-up, all patients received a chest X-ray (100%), 15/43 (34.8%) a CT scan, 8/43 (18.6%) a barium enema and 4/43 (9.3%) a US. RESULTS: No conversion to open surgery was reported. Average operative time was 61.2 min (range 45-110 min). In 38/43 (88.3%) patients, a trans-parietal stitch was positioned in order to reduce the tension during the repair. In 14/43 cases (32.5%), the sac was resected; in only 1/43 case (2.3%) a dual mesh of goretex was adopted to reinforce the closure. Average hospital stay was 2.8 days. The average follow-up was 4.2 years, and it consisted in annual clinical controls and chest X-ray. We recorded 2 complications (4.6%): one small pleural opening that required no drain and one recurrence (2.3%), re-operated in laparoscopy, with no further recurrence. CONCLUSIONS: To the best of our knowledge, this is the largest series published in the literature on this topic. Laparoscopic CMDH repair is well standardized: The full-thickness anterior abdominal wall repair using non-resorbable suture with interrupted stitches is the technique of choice. Postoperative outcome was excellent. Recurrence rate was very low, about 2% in our series. We believe that children with CMDH should be always treated in laparoscopy following the technical details reported in this paper.

PURPOSE: To compare the outcome of laparoscopic and retroperitoneoscopic approach for partial nephrectomy in infants and children with duplex kidneys. METHODS: Data of 102 patients underwent partial nephrectomy in a 5-year period using MIS procedures were analyzed. Fifty-two children underwent laparoscopic partial nephrectomy (LPN), and 50 children underwent retroperitoneoscopic partial nephrectomy (RPN). Median age at surgery was 4.2 years. Statistical analysis was performed using χ (2) test and Student's t test. RESULTS: The overall complications rate was significantly higher after RPN (15/50, 30 %) than after LPN (10/52, 19 %) [χ (2) = 0.05]. In LPN group, complications [4 urinomas, 2 symptomatic refluxing distal ureteral stumps (RDUS) and 4 urinary leakages] were conservatively managed. In RPN group, complications (6 urinomas, 8 RDUS, 1 opening of remaining calyxes) required a re-operation in 2 patients. In both groups no conversion to open surgery was reported. Operative time (LPN:166.2 min vs RPN: 255 min; p < 0.001) and hospitalization (LPN: 3.5 days vs RPN: 4.1 days; p < 0.001) were significantly shorter in LPN group. No postoperative loss of renal function was reported in both groups. CONCLUSIONS: Our results demonstrate that RPN remains a technically demanding procedure with a significantly higher complications and re-operation rate compared to LPN. In addition, length of surgery and hospitalization were significantly shorter after LPN compared to RPN. LPN seems to be a faster, safer and technically easier procedure to perform in children compared to RPN due to a larger operative space and the possibility to perform a complete ureterectomy in refluxing systems.

BACKGROUND: One-trocar laparoscopic appendectomy (OTA) is routinely adopted in children with acute appendicitis. In case of a difficult appendectomy, it is necessary to add additional trocar/s to safely complete the procedure. This technique is called multiport hybrid laparoscopic appendectomy (HLA). We aimed to compare the outcome of multiport HLA versus OTA. METHODS: We retrospectively reviewed the data of 1,092 patients underwent LA in 5 European centers of pediatric surgery in the last 5 years. We compared 2 groups: G1 of 575 patients (52.6 %) (average age 10 years) underwent OTA and G2 of 517 patients (47.4 %) (average age 8.2 years) underwent multiport HLA. RESULTS: No intra-operative complications occurred in both groups. An additional pathology was treated in 12 cases (8 Meckel's diverticulum, 2 carcinoids, 2 ovarian cysts) in G2. Operative time was significantly shorter in G2 compared to G1 (47.8 vs 58.6 min; p < .001). The average analgesic requirement was significantly shorter in G2 compared to G1 (44 vs 56 h; p < .001). As for postoperative complications, the incidence of port-site infections was similar between the two groups, while the incidence of postoperative abdominal abscesses (PAA) was significantly higher in G1 compared to G2 (4.7 vs 0.2 %; p < .001). The cosmetic outcome was excellent in all patients of both groups. A subgroup analysis between complicated and uncomplicated appendicitis showed that only in complicated cases, the average operative time, the average VAS pain score, the average analgesic requirements and the incidence of PAA were significantly higher in OTA group compared to multiport HLA group (p < .001). CONCLUSIONS: Our results suggest that OTA is a valid and safe procedure for the uncomplicated cases, while additional trocars are required in case of complicated appendicitis. Multiport HLA significantly reduces the operative time, the incidence of abdominal abscesses and the analgesic requirements compared to OTA.

OBJECTIVE: Recurrent tracheoesophageal fistula (RTEF) is a serious complication after primary repair of esophageal atresia and tracheoesophageal fistula (EA/TEF). Treatment of RTEF involved an open surgery by thoracotomy. Technically it is a challenge with a high morbidity and mortality. Congenital tracheoesophageal fistula (CTEF) traditionally involved an open surgery by thoracotomy or cervicotomy. Many endoscopic techniques have been developed since the past decades: thoracoscopic or bronchoscopic approach for the treatment of RTEF and CTEF; nevertheless, optimal treatment is not still determined because of few numbers of patients, short-term follow-up, and different procedures. We report our experience and evaluated the efficacy in the chemocauterization of CTEF and RTEF, with the use of 50% trichloroacetic acid (TCA) as a technique minimally invasive. MATERIALS AND METHODS: From 2010 to 2014, fourteen patients with TEF (twelve RTEF and two CTEF) were selected for endoscopic management in two centers. Twelve patients had RTEF after primary repair of EA/TEF by thoracotomy approach, and two patients had CTEF in the upper pouch, diagnosed after EA/TEF (Type B) long gap, treated by thoracotomy and thoracoscopy, respectively. In all cases the diagnosis was confirmed by esophagram, bronchoscopy, and clinical evaluation. Under general anesthesia, a rigid pediatric bronchoscope with a 0° rod lens telescope and tele-monitoring was used to localize the TEF. Cotton soaked with 50% TCA was applied on the TEF during 30 s, and the procedure was repeated 3 times. The endoscopic treatment was performed monthly until TEF closure was achieved. RESULTS: RTEF and CTEF were closed in all patients. The mean number of procedure in each patient was 1.8. Closure of TEF was confirmed by esophagram, bronchoscopy, and clinical evaluation. There were a bacterial pneumonia and bronchospasm as postoperative complications. Median follow-up was 41 months (8-72). All of these TEF remain completely obliterated, and all patients are asymptomatic. CONCLUSION: Endoscopic management of congenital and recurrent TEF with the use of 50% TCA is as a minimally invasive, effective, simple and safe technique in these patients and avoids the morbidity of open surgery.

BACKGROUND: We aim to report a 5-year retrospective multicentric European survey about the outcome of laparoscopic partial nephrectomy in infants and children with duplex kidneys. METHODS: The data of fifty-two children underwent laparoscopic partial nephrectomy (42 upper-pole nephrectomies and 10 lower-pole nephrectomies) in six European centers of Pediatric Surgery, were collected and analyzed. Median age at surgery was 5.1 years (range 6 months-9.7 years). There were 32 girls and 20 boys. In 37 patients, the left side was affected and in 15 patients the right side. For the right side, 4 trocars were used and for the left side 3/4 trocars. Special hemostatic devices were used for dissection and parenchymal section in all centers. We assessed intraoperative and postoperative morbidity. RESULTS: Median length of surgery was 166.2 min (70-215 min). No conversion to open surgery nor intraoperative bleeding was reported. Mean hospitalization was 3.5 days. We recorded 10/52 complications (4 urinomas, 2 recurrent UTIs, 4 prolonged urinary leakage), all managed conservatively. Reoperation rate was 0%. No loss of renal function on the residual kidney moiety was recorded in all operated patients. CONCLUSIONS: Laparoscopic partial nephrectomy remains a technically challenging procedure performed only in pediatric centers with high experience in minimally invasive surgery. Although the median operative time was higher than 2 h, we recorded no conversions in our series. The complication rate remains high (10/52-19.2%). All were II grade complications according to Clavien-Dindo classification and were treated conservatively without the need of other surgical procedures.

Introduction: Conservative management of primary obstructive megaureter (POM) appears as the best option in patients with adequate ureteral drainage. Nevertheless, surgical intervention is indicated in cases of recurrent urinary tract Infections (UTIs), deterioration of split renal function, and significant obstruction. The gold standard includes: Ureteral reimplantation with or without tapering by open approach. Our objective is to report our results in the treatment of POM by Laparoscopic-Assisted Extracorporeal Ureteral Tapering Repair (EUTR) and Laparoscopic Ureteral Extravesical Reimplantation (LUER) and to evaluate the efficacy and security of this procedure. Materials and Methods: From January 2011 to January 2018 a retrospective study was carried out by reviewing the clinical records of 26 patients diagnosed with POM. All patients underwent laparoscopic ureteral reimplantation following Lich Gregoir technique. In cases of ureteral tapering, an EUTR was performed with Hendren technique. Results: In all patients LUER and EUTR were performed without conversion. No ureteral tapering was necessary in six patients. There were no intraoperative complications. At 3 months in postoperative, 1 patient presented a febrile UTI, and subsequently, a vesicoureteral reflux (VUR) grade III was diagnosed by voiding cystourethrogram. In this case, a redo laparoscopic surgery was performed. After long-term follow-up, all patients were asymptomatic without recurrence of POM or VUR. Conclusion: Laparoscopic-assisted EUTR and LUER following Lich Gregoir technique for POM constitutes a safe and effective option, with a success rate similar to that of open procedure. Nevertheless, larger randomized prospective trials and long-term follow-up are required to validate this technique.

BACKGROUND: Robot-assisted extravesical ureteral reimplantation (REVUR) is a well established approach for surgical treatment of pediatric vesicoureteral reflux (VUR). However, further evidence is needed to confirm its efficacy even in case of complex anatomy. OBJECTIVE: This study aimed to further confirm the evidence that REVUR is safe and effective in both simple and complex ureter anatomy. STUDY DESIGN: The charts of all patients with VUR, who received REVUR in 6 different institutions over a 5-year period, were retrospectively reviewed. Patients with both simple and complex ureter anatomy were included. Patient demographics, surgical variables, and post-operative results were assessed. VUR resolution was defined as either being resolved VUR on voiding cystourethrogram (VCUG) or clinically without symptoms during the follow-up. RESULTS: Fifty-seven patients with median age of 6.9 years (range 4.5-12), receiving REVUR in the study period, were included. Eighteen (31.6%) patients had complex anatomy and included prior failed endoscopic injection (n = 13), complete ureteral duplication (n = 2), periureteral diverticulum (n = 2), ectopic megaureter requiring dismembering (n = 1). The median operative time was 155 min for unilateral and 211.5 min for bilateral repairs. The clinical + radiographic VUR resolution rate was 96.5%. Post-operative complications (Clavien 2) included urinary retention following bilateral repair (n = 5, 8.7%), febrile urinary tract infection (UTI) (n = 6, 10.5%) and gross hematuria (n = 3, 5.2%). Comparative analysis between simple and complex cases showed that REVUR was faster in simple cases in both unilateral [p = 0.002] and bilateral repair [p = 0.001] and post-operative urinary retention was more frequent in simple cases [p = 0.004] and in patients with pre-operative bowel and bladder dysfunction (BBD) [p = 0.001] (Table). DISCUSSION: This series confirmed that the robot-assisted technique was feasible even in cases with complex anatomy using some technical refinements, that justified the longer operative times in both unilateral and bilateral cases. An interesting finding of this study was the correlation emerged between BBD and risk of post-operative urinary retention and VUR persistence. Our results also excluded any significant correlation between complex cases and risk of post-operative urinary retention. The main study limitations included the retrospective and nonrandomized design, the small number of cases and the arbitrary definition of complex anatomy. CONCLUSION: REVUR was safe and effective for management of VUR in both simple and complex ureter anatomy. Complex REVUR required slightly longer operative times, without significant differences in post-operative mordidity and success rates. Aside from complex anatomy, BBD emerged as the main risk factor associated with surgical failure and post-operative morbidity.

BACKGROUND: The selection of best surgical approach for treatment of vesico-ureteral reflux (VUR) in the pediatric population remains debated. This study aimed to report the results of a multicenter survey about the current trends in surgical management of pediatric VUR. METHODS: An online questionnaire-based survey was performed, with participation of six international institutions. All children (age <18 years) affected by primary III-V grade VUR, who were operated over the last 5 years, were included. The incidence of each VUR intervention, patients' demographics and outcomes were analyzed. RESULTS: A total of 552 patients (331 girls), with a median age of 4.6 years (range 0.5-17.6), were included. Deflux® injection (STING) was the most common technique (70.1%). The multicenter success rate after single treatment was significantly lower after STING (74.4%) compared with the other treatments (P=0.001). Persistent VUR rate was significantly higher after STING (10.8%) compared with the other treatments (P=0.03). Choosing endoscopy over surgery mean reducing Clavien Dindo grade 2 complications by 5% but increasing redo procedure rate by 7%. STING was the most cost-effective option. CONCLUSIONS: This survey confirmed that the choice of the technique remains based on surgeon's preference. Deflux® injection currently represents the first line therapy for primary VUR in children and the role of surgical ureteral reimplantation is significantly reduced. STING reported acceptable success rate, less postoperative complications and lower costs but higher failure and re-operation rates and related costs compared with the other surgical approaches. The adoption of laparoscopy and robotics over open reimplantation remains still limited.

BACKGROUND DATA: EA is the most frequent congenital esophageal malformation. Long gap EA remains a therapeutic challenge for pediatric surgeons. A case case-control prospective study from a multi-institutional national French data base was performed to assess the outcome, at age of 1 and 6 years, of long gap esophageal atresia (EA) compared with non-long gap EA/tracheo-esophageal fistula (TEF). The secondary aim was to assess whether initial treatment (delayed primary anastomosis of native esophagus vs. esophageal replacement) influenced mortality and morbidity at ages 1 and 6 years. METHODS: A multicentric population-based prospective study was performed and included all patients who underwent EA surgery in France from January 1, 2008 to December 31, 2010. A comparative study was performed with non-long gap EA/TEF patients. Morbidity at birth, 1 year, and 6 years was assessed. RESULTS: Thirty-one patients with long gap EA were compared with 62 non-long gap EA/TEF patients. At age 1 year, the long gap EA group had longer parenteral nutrition support and longer hospital stay and were significantly more likely to have complications both early post-operatively and before age 1 year compared with the non-long gap EA/TEF group. At 6 years, digestive complications were more frequent in long gap compared to non-long gap EA/TEF patients. Tracheomalacia was the only respiratory complication that differed between the groups. Spine deformation was less frequent in the long gap group. There were no differences between conservative and replacement groups at ages 1 and 6 years except feeding difficulties that were more common in the native esophagus group. CONCLUSIONS: Long gap strongly influenced digestive morbidity at age 6 years.

BACKGROUND: The safety of the laparoscopic treatment of intestinal malrotation remains controversial. This study compared the outcomes of laparoscopic and open surgical treatment of intestinal malrotation. METHODS: A multicentric retrospective study included pediatric cases of intestinal malrotation operated on between 2005 and 2016. RESULTS: This study included 227 children with a median age of 17â¯days (0-17.2â¯years), including 161 with a midgut volvulus. Forty-six(20.3%) procedures were started by laparoscopy and 181(79.7%) by laparotomy. Laparoscopy was more frequent for elective surgery (45.9%) than for emergency procedures (10.8%, pâ¯<â¯0.001). Conversions were significantly more frequent during emergency procedures (66.7% vs 17.9%)(pâ¯=â¯0.001). Considering only 61 elective surgeries, the mean hospital stay was significantly shorter after laparoscopy (5.3â¯days +/-5.2 vs 10.1â¯days +/-13, pâ¯=â¯0.01), the overall complication rate was comparable (15.8% vs 21.7%, pâ¯=â¯0.7) but post-operative volvulus was significantly more frequent after laparoscopy (13% vs 0%, pâ¯=â¯0.04). Outcomes of the two approaches were not significantly different after 166 emergency procedures. CONCLUSION: Laparoscopy can be performed by experienced team for the treatment of selected cases of intestinal malrotation. Conversion to open surgery should be done with a low threshold, as the rate of volvulus recurrence is concerning. LEVEL OF EVIDENCE: Level III.

BACKGROUND: Minimally invasive surgery (MIS) for late-presenting congenital diaphragmatic hernia (CDH) has been described previously, but few neonatal cases of CDH have been reported. This study aimed to report the multicenter experience of these rare cases and to compare the laparoscopic and thoracoscopic approaches. METHODS: Using MIS procedures, 30 patients (16 boys and 14 girls) from nine centers underwent surgery for CDH within the first month of life, 26 before day 5. Only one patient had associated malformations. There were 10 preterm patients (32-36 weeks of gestational age). Their weight at birth ranged from 1,800 to 3,800 g, with three patients weighing less than 2,600 g. Of the 30 patients, 18 were intubated at birth. RESULTS: The MIS procedures were performed in 18 cases by a thoracoscopic approach and in 12 cases by a laparoscopic approach. No severe complication was observed. For 20 patients, reduction of the intrathoracic contents was achieved easily with 15 thoracoscopies and 5 laparoscopies. In six cases, the reduction was difficult, proving to be impossible for the four remaining patients: one treated with thoracoscopy and three with laparoscopy. The reasons for the inability to reduce the thoracic contents were difficulty of liver mobilization (1 left CDH and 2 right CDH) and the presence of a dilated stomach in the thorax. Reductions were easier for cases of wide diaphragmatic defects using thoracoscopy. There were 10 conversions (5 laparoscopies and 5 thoracoscopies). The reported reasons for conversion were inability to reduce (n = 4), need for a patch (n = 5), lack of adequate vision (n = 4), narrow working space (n = 1), associated bowel malrotation (n = 1), and an anesthetic problem (n = 1). Five defects were too large for direct closure and had to be closed with a patch. Four required conversion, with one performed through video-assisted thoracic surgery. The recurrences were detected after two primer thoracoscopic closures, one of which was managed by successful reoperation using thoracoscopy. CONCLUSIONS: In the neonatal period, CDH can be safely closed using MIS procedures. The overall success rate in this study was 67%. The indication for MIS is not related to weeks of gestational age, to weight at birth (if >2,600 g), or to the extent of the immediate neonatal care. Patients with no associated anomaly who are hemodynamically stabilized can benefit from MIS procedures. Reduction of the herniated organs is easier using thoracoscopy. Right CDH, liver lobe herniation, and the need for a patch closure are the most frequent reasons for conversion.

PURPOSE: The aim of this study was to report our initial experience with laparoscopic pyeloplasty (LP) in children with pelviureteric junction (PUJ) obstruction and describe the evolution and evaluate the results. MATERIALS AND METHODS: We retrospectively reviewed the records of 32 consecutive infants and children with unilateral ureteropelvic junction obstruction and deterioration of renal function on isotope renography, who underwent LP (19 on the right, 13 on the left) between May 2003 and January 2007. Twenty-three were males and 9 females. The mean age was 7.7 years old (range, 2 months to 17 years); the patient was placed in a three quarter lateral position and three ports were used. The PUJ was resected and the anastomosis was made by using absorbable sutures. A JJ stent was inserted by laparoscopy in most patients. Follow-up included clinical and ultrasound assessment, followed by isotopic renography at 6 months. RESULTS: LP was feasible in 29 of 32 patients (91%). The procedure could not be completed by laparoscopy in 3 patients; the main reason was difficulty in completing the anastomosis. Only 1 patient with a big redundant renal pelvis underwent a reduction. Stent insertion was successful in all, except 1 patient. An aberrant crossing vessel was found in 12 patients. We held up the aberrant crossing vessel and PUJ with two- or three-point-not absorbable-sutures, without the needed pyeloplasty in 2 of them. The other 10 underwent a LP enabled ureteric transposition. Three patients presented with postoperative complications: pyelonephritis in 2 patients and PUJ leakage in 1 who underwent nephrostomy with a further uneventful course. Mean operative time was 152 minutes (range, 120-270), and average hospital stay was 4.7 days (range, 1-8). In 1 patient, cystoscopy showed that the JJ stent was not in the bladder at the time of removal, and ureteroscopy was used to retrieve it. Mean follow-up was 22 months (range, 2-56). A total of 29 patients (91%) were asymptomatic after removal of the double JJ stent, showing a reduction of the degree of hydronephrosis in all patients, and had also improved PUJ drainage on isotope renography or sonography. CONCLUSIONS: LP is effective and safe in children with minimal morbidity and gives excellent short-term results. The feasibility is also excellent in patients younger than 1 year. The transabdominal approach revealed good exposition without disadvantages for the patient.

INTRODUCTION: The laparoscopic pull-through for high imperforate anus in boys has recently been developed in France and Benelux. The purpose of this study was to evaluate technical difficulties and surgical complications of this approach. PATIENTS AND METHODS: This report was based on a retrospective study from January 2002 to December 2007,including 34 patients from 10 centers. The rectourinary fistula found in 33/34 cases was bulbar in 10, prostaticin 20, and cervical in 3. RESULTS: Patients were 3.7 months old (range, 1.6-10.4) at surgery. Fistula was cut without closure in 11 cases or divided and closed on the genitourinary side with a suture in 15, with clips in five and linear stapler in two.Median operative duration was 152 mm (range, 80-410). The main per-operative complication, occurring in five cases, was leakage of stools from the rectum after the fistula section, requiring in one case a second laparoscopic procedure for washing and for all five cases intravenous antibiotics. Median hospital stay was 6 days(range, 3-15). During the follow-up, patients experienced eight anal stenoses and three prolapses, requiring in three cases perineal redo surgery. CONCLUSION: The laparoscopic approach of high imperforate anus allowed an easy control of the fistula and helped to determine the accurate passage through the levator ani. Nevertheless, technical points have to be improved,such as coprostasis before fistula section to avoid stool leakage, rectum tacking to prevent prolapse,and calibration of muscle channel to avoid stenosis.
