RESUMO
Nowadays laparoscopic Nissen fundoplication represents the gold standard in surgical treatment of complicated Gastro-Esophageal-Reflux Disease (GERD), above all in cerebral palsy patients. In non-neurological patients without gastrostomy Nissen fundoplication can create some problems (gas bloat syndrome, dysphagia). Laparoscopic Hill-Snow repair is an established surgical alternative, but it is reported only in adult population. We describe our modification of Hill-Snow technique and our experience in a large series of non-neurological children in order to report its effectiveness and applicability in pediatric patients affected by complicated GERD. Between 2000 and 2022, 319 children underwent surgical correction of gastro-esophageal reflux at our Department. All were affected by complicated gastro-esophageal reflux unresponsive to PPI (Proton Pump Inhibitors). 251 underwent laparoscopic Nissen fundoplication; 68 non-neurological patients underwent laparoscopic Hill-Snow repair. Of these 68 children 48 were males (71%) and 20 females (29%); median age was 5years (3 months-11 years). Weight range was 4-37kg. 52 patients (76.5%) presented the following symptoms: retrosternal pain, dysphagia, regurgitation, coughing, failure to thrive, persisting reflux esophagitis. 16 (23.5%) had chronic respiratory problems (aspiration, apneic-spells, dysphagia, coughing, choking, gagging). For 8 (11.8%) symptoms were expression of chronic recurrent gastric volvulus. All underwent modified-laparoscopic-Hill-Snow repair. Contrast study showed sliding hiatal hernia in 55 patients (81%), while endoscopy demonstrated 16 cases of histologically severe esophagitis (23.5%) and 52 of mild esophagitis (76.5%). No intraoperative/postoperative complications were recorded. 60patients had a complete follow-up (range 1-20 years). 60/68 patients were evaluated with barium-swallow-study at 6-12 months; 40/68 patients with upper-gastrointestinal-endoscopy at 12months. No relapse was reported. 50 patients (73.7%) were symptom-free. 18 (26.3%) referred occasional epigastric pain, associated with vomit in 2 cases. 64 (94.1%) referred ability to vomit; 4 temporary difficulty to swallow (average 30 days). All patients reported being able to burp. 3(4.5%) presented episodes of gas-air-bloat during the first 2 months with spontaneous resolution. No case of dumping syndrome was recorded. This technique's modification yields excellent results in term of relapse and side effects at long-term follow-up. We reported the first and largest pediatric series in non-neurological children with encouraging results.

Minimally invasive surgery (MIS) in pediatric population is becoming more and more popular among pediatric urologists and now it can be considered the best treatment for nephroureterectomy that is one of the most frequent urological procedures. The main indications to MIS ureteronephrectomy in children are congenital or acquired benign conditions such as nonfunctional and/or damaging kidney, renal dysplasia, and destroyed kidneys due to obstructive or refluxing uropathy. Since ever in open urological surgery, the lateral retroperitoneal approach represents the typical way to approach this kind of surgery. Although different surgical approaches can be chosen (i.e., posterior retroperitoneal, lateral retroperitoneal, laparoscopic transperitoneal, and robotic approach), the lateral retroperitoneal approach represents the typical way to perform this kind of surgery, also with minimally invasive techniques. In this article, we illustrate the technique of retroperitoneoscopic nephroureterectomy in infants and children, reporting our experience with this technique in the past 20 years.

The management of congenital primary obstructive megaureter (POM) is usually conservative, especially during the first year of life. Endoscopic high-pressure balloon dilatation (EHPBD) is indicated when symptoms, increasing dilatation and progressive renal damage are recorded, particularly in children younger than one year of age. We identified and described endoscopic prognostic factors predicting the success or failure of endoscopic dilatation. Thirty-eight patients (33 M;5 F) with POM from 2005-2018 were included. Diagnosis was based on US distal ureter dilatation (>7 mm), obstructive MAG-3 diuretic renogram and absence of vesicoureteral reflux (cystography). 24 patients were under 1 year of age. All patients underwent cystoscopy and high-pressure balloon dilatation with 3,5 Fr dilating balloon, after ascending pyelography. Median follow-up was of 6.5 years. We identified characteristics with poor prognosis: stenotic punctiform ureteral ostium and/or ostium located in a bladder diverticulum (9 pts) and stenotic tract longer than 1 cm (5 pts). The patients with a stenotic tract shorter than 1 cm (18 pts) were divided into two groups: <5 mm (5 pts) and between 5 and 10 mm (13 pts) showed a good response to dilatation. Endoscopic evaluation of ureteral ostium with pneumatic dilatation when possible is a useful diagnostic and therapeutic solution for POM treatment, especially under one year of age. EHPBD is effective in short stenotic tracts (<5 mm). It may also be repeated with good results in intermediate stenotic sections (5 mm-1 cm). According to our preliminary results, the procedure is more effective if performed earlier (3-7 months of life). Greater cohort and longer follow-up are needed to verify the stability of these results.

Ureteral atresia is a rare disease usually associated with a non-functioning dysplastic kidney. The condition may be unilateral or bilateral; focal, short or long and may involve any part of the ureter. Association with other urinary anomalies is rare. We report the case of a 10-month-old boy with prenatal diagnosis of multicystic right kidney. This suspicion was confirmed after birth by ultrasound and static scintigraphy; a right vesicoureteral reflux (VUR) was recorded at cystography. The boy presented a regular renal function but was hospitalized twice for suspected pyelonephritis between the 8th and the 10th month of life and were recorded occasional mild changes in blood pressure. Antibiotic prophylaxis was administered until surgery. When he was 10-month underwent retroperitoneoscopy to perform a nephroureterectomy finding a complete atresia of the upper third of the ureter with the blind end at the level of the uretero-pelvic-junction. The programmed surgery was performed. By a revision of literature, only few cases of imperforate distal ureter have been described. This condition is associated with a kidney dysplasia. The atresia of the ureter with no signs of infection in the dysplastic kidney may be unknown up to adulthood or throughout one's life. Prognosis usually depends on the severity of the obstruction.
RESUMO
Objective. Duodenal atresia (DA) routinely has been corrected by laparotomy and duodenoduodenostomy with excellent long-term results. We revisited the patients with DA treated in the last 12 years (2004-2016) comparing the open and the minimally invasive surgical (MIS) approach. Methods. We divided our cohort of patients into two groups. Group 1 included 10 patients with CDO (2004-09) treated with open procedure: 5, DA; 3, duodenal web; 2, extrinsic obstruction. Three presented with Down's syndrome while 3 presented with concomitant malformations. Group 2 included 8 patients (2009-16): 1, web; 5, DA; 2, extrinsic obstruction. Seven were treated by MIS; 1 was treated by Endoscopy. Three presented with Down's syndrome; 3 presented with concomitant malformations. Results. Average operating time was 120 minutes in Group 1 and 190 minutes in Group 2. In MIS Group the visualization was excellent. We recorded no intraoperative complications, conversions, or anastomotic leakage. Feedings started on 3-7 postoperative days. Follow-up showed no evidence of stricture or obstruction. In Group 1 feedings started within 10-22 days and we have 1 postoperative obstruction. Conclusions. Laparoscopic repair of DA is one of the most challenging procedures among pediatric laparoscopic procedures. These patients had a shorter length of hospitalization and more rapid advancement to full feeding compared to patients undergoing the open approach. Laparoscopic repair of DA could be the preferred technique, safe, and efficacious, in the hands of experienced surgeons.

Horseshoe kidney (HSK) is a congenital defect of the urinary tract that occurs in 0.25% of the general population. Laparoscopic Vascular Hitch (LVH) according to Hellstrom-Chapman represent an alternative approach in treatment of extrinsic hydronephrosis by crossing vessels (CV) in pediatric age. In our Department from 2006 to 2016, 36 children with extrinsic-Uretero-Pelvic-Junction (UPJ)-Obstruction (UPJO) underwent laparoscopic vessels transposition. Over the last 4years, we have treated three patients with extrinsic hydronephrosis in HSK; two males and one female respectively of 6, 7 and 8years. The side affected was the left in all patients; symptoms of onset: recurrent abdominal pain, vomiting with associated intermittent hydronephrosis at ultrasonography. The preoperative examinations performed were: ultrasound/Doppler scan, MAG3-renogram, functional-magnetic-resonance-urography (fMRU). Mean operative time was 120'; median hospital stay 3- days. Intraoperative diuretic-test (DT) confirmed an extrinsic-UPJO in all patients. No JJ-stents and drain were used and there were no perioperative complications. Clinical and ultrasound follow-up (18 months-4 years) show resolution of symptoms and decrease in hydronephrosis grade in all patients. Our series is the largest in pediatric population by a revision of the literature. We believe that LVH is feasible in patients with symptomatic hydronephrosis by CV in HSK. Intraoperative-DT and the correct selection of patients are crucial to the success of the technique. According to us, this procedure is appropriate in those cases where the UPJ-anatomy is disadvantageous to a resection/re-anastomosis between ureter and renal pelvis. Our initial results are encouraging, although long-term follow- up and a more significant patient sample are required.

PURPOSE: We report the results of laparoscopic vascular hitching (LVH) in a series of children with ureteropelvic junction obstruction (UPJO) owing to aberrant lower polar crossing vessels (CV). Our aim is to confirm if LVH associated with intraoperative diuretic test (DT) represents a good procedure to treat extrinsic-UPJO by CV. In order to confirm the relief of the obstruction we suggest performing an intraoperative DT. MATERIALS AND METHODS: In our department from 2006 to 2014, 120 patients were treated for both extrinsic and intrinsic-UPJO. 85 (30 females, 55 males) presented an intrinsic obstruction and underwent dismembered pyeloplasty (AHDP), 61 open, 16 laparoscopic, 8 retroperitoneoscopic. 35 (23 males, 12 females) were studied for a suspected extrinsic-UPJO: 30 were treated with LVH (modified Hellström vascular hitch). Intraoperative-DT was performed in all patients before and after vessel transpositions confirming the UPJO and eventual relief after the procedure. We included in the study only patients with suspicion of vascular extrinsic-UPJO. Average age at surgery was 7.5years. Symptoms of presentation were recurrent abdominal/flank pain and hematuria. All patients presented ultrasound (US) detection of hydronephrosis. Preoperative diagnostic studies include: US/doppler scan, MAG3 renogram, urography, functional magnetic resonance urography (fMRU) and CT scan. RESULTS: 28 out 35 patients had a correct preoperative diagnosis, and the remaining needed an intraoperative diagnosis confirmation. All 35 patients had an intraoperative-DT: 30 patients underwent LVH (positive-DT); 3 patients (negative-DT) underwent laparoscopic-AHDP for intrinsic-UPJO; two with positive-DT and nonobstructive CV, had no surgical treatment. Median operating time was 95min; mean hospital stay was 4days. At 12-84months follow-up 29 patients remained symptoms-free, one needed after two years a laparoscopic-AHDP. CONCLUSIONS: According our experience, LVH associated with intraoperative-DT may be considered a safe procedure to treat extrinsic-UPJO by CV in carefully selected patients. In particular, the very low incidence of relapse suggest that in suspicion of extrinsic-UPJO, performing intraoperative-DT after CV transposition allows to exclude intrinsic-UPJO confirming that the LVH-procedure has relieved the pelvic obstruction, precluding the need for AHDP.

Nephrogenic adenoma is a rare, benign lesion of the bladder, occurring as an epithelial response to chronic infection or trauma, probably arising from nephrogenic metaplasia. In contrast to nephrogenic adenomas in adults, who present with this tumor in the entire ureteral tract, it has been observed exclusively in the bladder of children thus far. We report and discuss here the case of a 12-year-old boy with diffuse calculus-producing nephrogenic adenoma successfully treated with sodium hyaluronate.
RESUMO
Thrombocytopaenia occurs during necrotizing enterocolitis (NEC), and nadir platelet count is associated with extent of disease. In paediatric meningococcal disease, the product of neutrophil and platelet count at admission is prognostically useful. We therefore aimed to determine whether the first full blood count (FBC) after diagnosis of NEC is useful as a score for poor outcome and severity of disease. Between 1987 to 2001, neutrophils (N), platelets (P) and their product (PN) was available in 187 neonates treated for NEC at our institution. Neonates with NEC were grouped according to the extent of disease (no gangrene, focal, multifocal and pan-intestinal). Data were not normally distributed so Mann-Whitney U test or analysis of variance (ANOVA) on logged data were used ( p<0.05 was considered significant). Receiver operating characteristics (ROC) curves were used to examine the relationship between specificity and sensitivity. A perfect test would have an ROC curve area of 1. Initial P count and PN product of non-survivors were both significantly lower than in survivors ( p<0.0001), whereas N was not different ( p<0.08). Low Log(10)PN was significantly associated with greater extent of disease (ANOVA; no gangrene vs multifocal, p<0.01, vs panintestinal, p<0.0005), suggesting that the initial FBC could be prognostically useful. Area under the ROC survival curve for neutrophils was 0.58, for platelets 0.75 and for PN product 0.71; thus, although no test performed extremely well, initial platelet count and NP product could be useful in evaluating disease severity in neonates with NEC and for further monitoring.
