Background: There are limited data about urolithiasis in young infants, especially in class age younger than 2 years. Case presentation: We report the case of a child

The literature reported an increased avoidance of the Emergency Department (ED) during COrona VIrus Disease 19 (COVID-19) pandemic, causing a subsequent increase of morbidity and mortality for acute conditions. Testicular torsion is a surgical emergency, which can lead to the loss of the affected testicle if a delayed treatment occurs. As testicular loss is time-related, outcome was hypothesized to be negatively affected by the pandemic.The aim is to investigate whether presentation, treatment and outcomes of children with testicular torsion were delayed during COVID-19.Medical records of pediatric patients operated for testicular torsion of six Paediatric Surgical Units in Northern Italy between January 2019 and December 2020 were retrospectively reviewed. Patients were divided as for ones treated during (dC) or before the pandemic (pC). To reflect possible seasonality, related to lockdown restrictions, winter and summer calendar blocks were also analysed. For all cohorts, demographic data, pre-operative evaluation, operative notes and post-operative outcomes were reviewed. Primary outcomes were referral time, time from diagnosis to surgery and ischemic time, while secondary outcomes were orchiectomy and atrophy rates. Statistic was conducted as appropriate.A total of 188 patients with acute testicular torsion were included in the study period, 89 in the pre-COVID-19 (pC) period and 99 during COVID-19 (dC). Time from symptom onset to the access to the Emergency Department (T1) was not different among the two populations (pC: 5,5 h, dC: 6 h, p 0.374), and similarly time from diagnosis to surgery (pC: 2,5 h, dC: 2,5 h, p 0.970) and ischemic time (pC: 8,2 h, dC: 10 h, p 0.655). T1 was6 h in 46/99 patients (46%) pC and 45/89 patients (51%) dC (p = 0.88, Fisher's exact test). Subgroup analysis accounting for different lockdown measures, confirm the absence of any difference. Orchiectomies rate was 23% (23/99) dC and 21% (19/89) pC (p = 0.861, Fisher's exact test) and rate of post-operative atrophy was 9% dC (7/76) and 14% pC (10/70), p = 0,44, Fisher's exact test.Despite worldwide pediatric ED accesses reduction, we reported that neither ischemic time nor the long-term outcomes in children with testicular torsion increased during the COVID-19 pandemic. In the available literature, few studies investigated the topic and are controversial on the results. Similarly to our findings, some studies found that timing and orchiectomy rates were not significantly different during the pandemic, while others reported a correlation to pandemic seasonality. Furthermore, in the recent pediatric literature it has been reported a delayed testicular torsion diagnosis due to shame in informing parents. Strengths of this study are the large numerosity, its multicentric design and a long study period. Its main limitation is being retrospective.We reported our large cohort from one of the most heavily COVID-19-affected regions, finding that referral, intra-hospital protocols and ischemic time in testicular torsion were not increased during to the pandemic, as well as orchiectomy rate and atrophy.

In pediatric patients appendicitis is the most common cause of abdominal pain and surgery. Torsion of vermiform appendix is a rare cause, clinically indistinguishable from appendicitis with usually an intraoperative diagnosis. The first description of vermiform appendix torsion was made by Payne in 1918. Clinical presentation is similar to acute appendicitis. Preoperative investigations play a minimal role. Etiology of this condition is unclear, but is possible to distinguish a primary and a secondary torsion. We report a case of 5-years-old boy who presented with right lower quadrant abdominal pain. His clinical signs, symptoms and investigations mimicked an acute appendicitis. Intraoperatively we found a 720° appendix torsion on its base with its mesentery rotated in counter-clockwise direction. The appendix was gangrenous in appearance. A video-assisted trans-umbilical appendectomy was performed. We describe clinical presentation and management of this rare condition reviewing the literature.

Majority of sequestrations fall into two categories: Intra-Lobar (ILS) and Extra-Lobar (ELS). Rarely the abnormal lung could be attached to the gastrointestinal tract, Bronchopulmonary Foregut Malformation (BPFM). We described a case of a girl of 3-years-old with antenatal diagnosis of left intrathoracic mass of the inferior lobe. Postnatal Computed-Tomography (CT) revealed a bilateral ELS with an isthmic bridge crossing the vertebral spine. She follows a MRI follow-up at 18months/30months confirming the lesion. Before surgery, a three-dimensional-CT-angiography was performed to study the mass, its blood supply and to plan surgery. She underwent to thoracoscopic resection. Two aberrant blood vessels were dissected from the thoracic aorta and ligated. The postoperative course was uneventful. She was discharged after 3 days. The rarity of our case is due to the bilateral extension. An appropriate preoperatory imaging study is necessary for the success of surgery while thoracoscopy is particularly appropriate in surgical treatment.

In the last three decades, fetal ovarian cysts were diagnosed more frequently, due to technological improvement and the increasing use of prenatal screening ultrasound. Nonetheless, treatment uncertainties are still present, either prenatally or postnatally. Recently, significant innovations on diagnosis and treatment have been proposed and a more conservative, minimally invasive approach may be offered to the Pediatrician or the Surgeon who face with this condition during prenatal or neonatal age.

The most appropriate treatment for the infantile Hypertrophic Pyloric Stenosis (HPS) is still debated. The non-surgical conservative treatment with oral or intravenous administration of atropine does not enjoy a widespread appreciation for several factors (...)

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.

Esse sono frutto di un lungo lavoro di revisione sistematica della letteratura integrato dal parere di esperti nel campo della Chirurgia Mininvasiva Pediatrica. Queste linee guida sono intese ad aiutare il chirurgo pediatra che si avvicina, o già pratica, la Chirurgia Mininvasiva, ed hanno lo scopo di facilitare la scelta dell’indicazione e del trattamento chirurgico ottimale per le principali patologie chirurgiche pediatriche. Tuttavia, data la complessità delle malformazioni congenite, delle patologie chirurgiche pediatriche e l’estrema varietà dell’ambiente sanitario, è importante sottolineare come l’approccio suggerito potrebbe non essere necessariamente l’unico approccio accettabile e/o percorribile. Le linee guida devono essere considerate uno strumento flessibile in quanto poi è il medico che, con il consenso dei genitori/tutori, avrà il compito di scegliere l’approccio più adatto al singolo paziente.

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

Throughout history, the pediatric laparoscopic nephrectomy was first described at the beginning of the Nineties by Erlich and colleagues in a child and by Koyle and colleagues in an unweaned patient. (...)

Congenital esophageal stenosis (CES) is a very rare condition caused by ectopic tracheobronchial remnants (TBR), segmental fibromuscular hypertrophy (FMS) or membranous diaphragm (MD). In 25% of patients, CES is associated with esophageal atresia (EA). We present a challenging case report and we review the literature. Esophagogram conducted after a type III EA thoracoscopic correction, showed a sub-anastomotic CES 1 cm above cardia. EGDS confirmed it and CT-scan deposed for segmental fibromuscular hypertrophy. After conservative management failure (taper and balloon dilations), the patient underwent surgery through a laparoscopic approach. Intraoperative finding of a tracheobronchial remnant forced the surgeon to abandon the standard technique: because of the cardia proximity, esophageal resection and anastomosis were not possible without removing the cardia. New solution applied was successful: a postoperative contrast study and EGDS demonstrated CES resolution and, at one year follow up, the patient was symptom-free. The correct definition of CES anatomical features and position is critical to choose the best therapeutic approach. The technique we applied led to an anatomical and clinical resolution, but, as highlighted in literature, a longer follow up is needed to confirm the efficacy of treatment.

Epididymal cysts (ECs) are relatively common in adults, rare in children. Normally their treatment is conservative. They may be situated anywhere in the organ, frequently in the region of the head. Torsion of these cysts is extremely rare in both children and adults, causing acute scrotal swelling. The diagnosis is intraoperative. A 16-year-old boy was referred to our Divisional Clinic by the treating physician for scrotal swelling appeared 4 months earlier. Absence of a history of minor scrotal trauma. Ultrasonography showed a 40×50 mm fluid-filled right para-testicular mass. We performed surgery finding a large black cyst connected to the head of the epididymis with 720°-degrees rotation. Histology revealed an acquired EC. The particularity of our case is due to the absence of symptoms in association with a big EC twisted of 720° degrees. This is the only case reported in literature. All patients with EC torsion reported presented symptoms related to acute scrotum.

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.

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.

Background: Congenital hydronephrosis due to intrinsic or extrinsic uretero-pelvic-junction (UPJ) obstruction (UPJO) is a common problem in childhood UPJO may be caused by intrinsic disorganization or by extrinsic compression from crossing vessels (CV); extrinsic causes usually present symptomatically in older children. This report the large Italian experience in the treatment of children with extrinsic-UPJO by CV. Methods: We analyzed the data of 51 children (17 girls and 34 boys, median age 10, 7 years) affected by extrinsic-UPJO were treated in three Italian institutions with laparoscopic transposition of CV (Hellstrom Vascular Hitch modified by Chapman).The intraoperative diuretic-test was performed in all patients before and after the vessels transpositions confirming the extrinsic-UPJO. We included in the study only patients with suspicion of vascular extrinsic obstruction of the UPJ. Symptoms at presentation were recurrent abdominal/flank pain and haematuria. All patients presented intermittent ultrasound (US) detection of hydronephrosis (range: 18–100 mm). Preoperative diagnostic studies included: US/doppler scan, MAG3-renogram, functional-magnetic-resonance-urography (fMRU). Results: Median operative time was 108 minutes; median hospital stay: 3, 4 days. Unique complications: a small abdominal wall hematoma and higher junction-translocation without obstruction. During follow-up (range: 12–96 months) all patients reported resolution of their symptoms, a decrease in the hydronephrosis grade and improved drainage on diuretic renogram. Conclusions: We believe that Vascular Hitch is less technically demanding than laparoscopic pyeloplasty, resulting in a lower complication rate and a significantly reduced hospitalization. The results of our study allow us to conclude that laparoscopic VH may be a safe, feasible, and attractive alternative to treat obstructed hydronephrosis due to CV presenting a useful alternative to AHDP in the management of symptomatic children where CV are deemed the sole aetiology. We recommend careful patient selection based on preoperative clinical and radiologic findings that are diagnostic of extrinsic-UPJO, combined with intraoperative-DT to confirm the appropriate selection of corrective procedure.

Study Objective To report results of a retrospective multicentric Italian survey concerning the management of pediatric ovarian torsion (OT) and its recurrence. Design Multicenter retrospective cohort study. Setting Italian Units of Pediatric Surgery. Participants Participants were female aged 1-14 years of age with surgically diagnosed OT between 2004 and 2014. Interventions Adnexal detorsion, adnexectomy, mass excision using laparoscopy or laparotomy. Different kinds of oophoropexy (OPY) for OT or recurrence, respectively. Main Outcome Measures A total of 124 questionnaires were returned and analyzed to understand the current management of pediatric OT and its recurrence. The questionnaires concerned patient age, presence of menarche, OT site, presence and type of mass, performed procedure, OPY technique adopted, intra- and postoperative complications, recurrence and site, procedure performed for recurrence, OPY technique for recurrence, and 1 year follow-up of detorsed ovaries. Results Mean age at surgery was 9.79 ± 3.54 years. Performed procedures were open adnexectomy (52 of 125; 41.6%), laparoscopic adnexectomy (25 of 125; 20%), open detorsion (10 of 125; 8%), and laparoscopic detorsion (38 of 125; 30.4%). Recurrence occurred in 15 of 125 cases (12%) and resulted as significant ( P = .012) if associated with a normal ovary at the first episode of torsion. Recurrence occurred only in 1 of 19 cases after OPY (5.2%). Ultrasonographic results of detorsed ovaries were not significant whether an OPY was performed or not ( P = 1.00). Conclusion Unfortunately, oophorectomy and open technique are still widely adopted even if not advised. Recurrence is not rare and the risk is greater in patients without ovarian masses. OPY does not adversely affect ultrasonographic results at 1 year. When possible OPY should be performed at the first episode of OT.

The first cases of atresia or web in the pyloric and prepyloric regions were described in the literature since 1937. To date, only one case of atresia at the junction between the fundus and the body of the stomach has been reported. We want to describe a complex case with incomplete atresia between fundus and gastric body, with left lateral diaphragmatic hernia, treated in several stages by endoscopic, open surgery and minimally invasive surgery
