Introduction: Congenital webbed penis (CWP) describes a condition in which the ventral skin of the penis is fused with the median raphe of the scrotum, thereby obscuring the penoscrotal angle. Materials and methods: We retrospectively reviewed the clinical notes of 21 patients undergoing treatment of CWP with “V-I penoscrotal reconfiguration technique”. CWP was assessed according to the classification of El-Koutby which includes Grade 1: the webbed skin reaches the proximal 1/3 of the penile shaft; Grade 2: the webbed skin extends to the mid 1/3 of the penis; Grade 3: the web extends to the distal 1/3 of the shaft. If phimosis was associated, this was graded according to Meuli’s classification into 4 degrees. The degree of parental satisfaction was quantified in 5 degrees according to the Likert Scale: “very unsatisfied”: score 0; “unsatisfied”: score 1; “neither satisfied nor unsatisfied”: score 2; “satisfied”: score 3; “very satisfied”: score 4. Results: CWP was grade 3 in 11 patients (52%), grade 2 in 5 patients (24%), and grade 1 in 5 patients (24%). Furthermore, it was present as isolated malformation (5 cases, 24%), associated with phimosis (11 cases, 52%), associated with hypospadias (3 cases, 14%), associated with hypospadias and phimosis (2 cases, 10%). Post-operative follow-up included clinical assessments at 2 weeks and then at 1, 6, and 12 months. No postoperative complications were noted during the follow-up. Even the one-year follow-up did not show any blemishes or scar retractions with penile curvature. In no case was necessary a reoperation. The aesthetic result was excellent in all cases. Regarding the parental satisfaction score in 17 cases parents reported a score of 4 and the remaining 4 a score of 3, especially for the aspect of the circumcised penis. Conclusions: The webbed penis is an infrequent congenital malformation, which causes psychological distress, especially in parents. Additionally, possible functional problems may arise during sexual activity in adulthood. Its correction in pediatric age is therefore desirable, to prevent possible psychological and sexual. In our opinion, the described “V-I reconfiguration technique” is simple to perform, and easy to reproduce with excellent aesthetic and functional results.

Inguinal hernia repair is one of the most common pediatric surgeries that can be approached with an open or laparoscopic approach. Aim of this study was to describe outcomes and complications of Flip Flap inguinal hernia repair analyzing our experience in the last 5 years.280 children admitted at our Department with inguinal hernia requiring surgery between 2015 and 2020 were included. Secondary aim was to investigate how confidence of surgeons regarding VLS approach increase during time and how this particular technique represents a primary procedure useful to increase surgeons' skills in performing laparoscopic sutures.160 children (57%) underwent open approach, whereas 120 (43%) laparoscopic ligation of hernia. For each groups clinical and surgical data were recorded. We focused on comparing post-operative complications: the most frequent complication was hydrocele (n 4, 1.4%). Reported post-operative complication were not statistically different between two groups (open n=3, 1.8% vs laparoscopy n=1, 0.8%). No other postoperative complications were documented in our cohort for both groups. In laparoscopical group we registered 3 cases of ipsilateral recurrence (1.6%) and no cases of metachronous hernia.The choice of laparoscopic approach significanty increased from 22% in 2015 to 74% in 2020 (p0.05) as well as the percentage of male underwent to laparoscopical procedure (38% in 2015 to 74% in 2020, p0.05).It is known that the rate of complication or recurrence is similar for open or minimally invasive inguinal hernia repair. Laparoscopy offers advantages such as the possibility of visualize contralateral internal inguinal ring, reducing the incidence of methacronous inguinal hernia. Moreover, taking confidence with a minimally invasive technique such Flip Flap hernioplasty by performing it repeatedly over time, leads to an improvement of surgeons skills also in performing laparoscopic sutures, that can be helpful for other complex or tricky procedures.

Introduction: The recycling of proximal stoma losses is known as a good practice to manage patients with high output stoma. In our center, we introduced this practice about 10 years ago. We revised our series before and after recycling protocol and we reviewed the literature. Methods: This is a retrospective study. We included all neonates who underwent ileostomy between 2000 and 2019. They were divided into two groups, Group A and Group B, before and after the introduction of recycling of stoma losses. Demographic data were included. Outcomes evaluated to demonstrate the efficacy of stools recycling were: weight at the time of anastomosis and at discharge, length of total parenteral nutrition, and time (expressed in days) between anastomosis and passage of the stools. Data were analyzed using Student’s t-test. P values Results: A total of 85 patients (29 females, 56 males) were included—Group A: 20 (24%) (13 males/7 females); Group B: 65 (76%) (43 males/22 females); Group A: 12/enterocolitis, 5/meconium-related ileum (MRI), 3/single intestinal perforation; Group B: 45 enterocolitis, 10/MRI, 8/single intestinal perforation, 1/an ileal atresia, 1/meconial peritonitis. Outcome about weight at anastomosis and discharge and about time of canalization were significant. Conclusion: We believe that the recycling of stoma losses is a safe and effective practice in neonates with ileostomy. Our technique of recycling is simple and practical. The benefit/risk rate is certain, in our opinion, in favor of the benefits as showed from our data.

Aim: To describe architecture and expression of myosin isoforms of the human cremaster muscle (CM) and to individuate changes in clinically differentiated abnormalities of testicular descent: cryptorchidism or undescended testis (UDT) and retractile testis (RT). Background: The CM is a nonsomitic striated muscle differentiating from mesenchyme of the gubernaculum testis. Morphofunctional and molecular peculiarities linked to its unique embryological origin are not yet completely defined. Its role in abnormalities of testicular descent is being investigated. Subjects and Methods: Biopsy samples were obtained from corrective surgery in cases of cryptorchidism, retractile testis, inguinal hernia, or hydrocele. Muscle specimens were processed for morphology, histochemistry, and immunohistology. Results and Conclusions: The CM differs from the skeletal muscles both for morphological and molecular characteristics. The presence of fascicles with different characterization and its myosinic pattern suggested that the CM could be included in the specialized muscle groups, such as the extrinsic ocular muscles (EOMs) and laryngeal and masticatory muscles. The embryological origin from the nonsomitic mesoderm is, also for the CM, the basis of distinct molecular pathways. In UDT, the histological alterations of CM are suggestive of denervation; the genitofemoral nerve and its molecular messengers directed to this muscle are likely defective. Compared with the other samples, RT has a distinct myosinic pattern; therefore, it has been considered a well-defined entity with respect to the other testicular descent abnormalities.

Lichen Sclerosus (LS) is a chronic inflammatory skin disease with unknown etiology. In pediatric age the main disease “lichenlinked” is the phimosis in male. This is a retrospective study that reports the experience of our clinic and review of the literature. We included all patients affected by pathological phimosis, treated by circumcision between January 2015 and May 2020, older than 6 years old and with an histopathological diagnosis of lichen sclerosus. The aim was to identify prognostic factors based on histological report to plan the clinical management of patients. Statistical analysis was done. We included 207 patients. The mean age of children was 9,78 years (5-18 years, DS±3.29). Based on the histological features we divided patients in 2 groups: early lesions (70/207, 34%) and advanced (137/207, 66%). In term of complications lichen linked we considered meatal stenosis that needed of urethral dilatations. We included 7 patients (7/207, 3,4%). We report P value Statistical Significance in many aspects. An early diagnosis of LS and surgical treatment of foreskin are essential to prevent early and late complications in children. The size of sample is a limit of the study but results encourage our management.

Introduction There is a need to develop sensitive markers to diagnose or monitor the severity of intestinal damage in necrotizing enterocolitis (NEC). Mitochondrial deoxyribonucleic acid (mtDNA) is increased in the intestine and blood of adults in response to intestinal ischemia and can trigger secondary organ damage. We hypothesize that mtDNA is increased during experimental NEC and that mtDNA levels are correlated to the degree of intestinal injury. Materials and Methods NEC was induced in C57BL/6 mice (n = 18) (approval: 44032) by gavage feeding with hyperosmolar formula, hypoxia, and lipopolysaccharide administration from postnatal day (P) 5 to 9. Breastfed pups served as control (n = 15). Blood was collected by cardiac puncture and terminal ileum was harvested on P9. Reverse transcription quatitative polymerase chain reaction was used to measure mtDNA (markers COX3, CYTB, ND1) and inflammatory cytokines (interleukin 6 [IL-6] and tumor necrosis factor-α[TNF-α]) in blood and ileum. Intestinal injury was scored blindly by four investigators and classified as no/minor injury (score 0 or 1) or NEC (score ≥2). Results mtDNA is significantly increased in gut and blood of NEC mice (p Conclusion Following NEC intestinal injury, mtDNA is released from the intestine into circulation. The blood level of mtDNA is related to the degree of intestinal injury. mtDNA can be a novel marker of intestinal injury and can be useful for monitoring the progression of NEC.

Hypertrophic pyloric stenosis (HPS) is the most important cause of non-bilious vomiting during infancy and it is usually idiopathic. It is very rare in older children and adolescents, in which gastric outlet obstruction (GOO) is more typically secondary to other conditions. Gastrointestinal malformation are frequently associated with Down syndrome and some of them (especially duodenal abnormalities) can be detected quite late. In infants the standard treatment of HPS is represented by a Ramstedt pyloromyotomy, while in adults a distal gastric resection is more indicated and it is usually associated to a Billroth I or II reconstruction. Case report We present an unusual case of a 12-year-old girl with Down syndrome, diagnosed with late-onset HPS. She came to our attention with periodic non-bilious vomiting and growth delay. She underwent multiple imaging examinations, which highlighted the presence of an HPS. Based on patient's age and the thickness of the pyloric muscle, we decided to perform a partial gastrectomy with a Roux-en-y reconstruction. Patient was discharged on the X day. She is now on follow up, gains weight and presents good conditions. Discussion HPS is rare but possible during childhood and adolescence. Diagnosis is usually performed through ultrasounds (US) and upper gastrointestinal radiological series (UGI), but sometimes further examinations are required (abdominal MRI, esophagogastroduodenoscopy). In older children since less invasive techniques are not effective, we have to consider partial gastrectomy. Based on our experience, Roux-en-y reconstruction is a valid option, associated with poor complication and good quality of life.

Introduction Juvenile myasthenia gravis (JMG) is a rare debilitating and potentially fatal autoimmune disease, with unclearify pathogenesis. Surgical immunomodulation with thymectomy has been repeatedly demonstrated to be a safe and effective treatment for JMG in both adult and pediatric patients. In the last few years, minimally invasive approach and above all robotic assisted thoracoscopy, replaced sternotomy which is widely used in adult patients. We report our experience in a case of robot-assisted thoracoscopic thymectomy approach in a 12 years old boy for juvenile myasthenia gravis (JMG). Case report Procedure was performed with the Da Vinci surgical robot (Xi) using left-sided approach. Left lung was kept out from mechanic ventilation. A 8 mm port for the 3-D camera was introduced on the V intercostal space on the anterior axillary line. Others two 8mm thoracic ports were placed under vision after the induction of a low-pressure pneumothorax, respectively on the midaxillary line on the III intercostal space and on the parasternal space on the V intercostal space. Bulk resection of gland was made using Maryland grasper and Harmonic scalpel, starting at level of the left pericardiophrenic angle and continuing cranially. Thymus was unstick from the posterior face of the sternum until the right pleura releasing lower thymic horns. After that, controlateral right-side thymectomy was continued into the neck to include the upper horns and finally it was removed with an endocatch bag. Histopathological examination showed a benign thymic hyperplasia. There were no perioperative and postoperative complications. The discharge was on IV post-operative day. After thymectomy, patient reported an improvement in symptoms and stopped medical therapy with pyridostigmine. Conclusions VATS and Robotic thoracoscopic thymectomy have increasingly taken hold in recent years. The surgical treatment offered to patient an improvement in clinical status. Surgery by robotic assistance has demonstrable advantages, including three-dimensional visualization and articulating instruments. Left lateral approach provided excellent visualization of the thymic veins, anonymous vases and phrenic nerves. Three-dimensional visualization as well as articulating arms greatly facilitated the dissection compared with standard thoracoscopic technique. In Literature very few series of robotic approach for surgical treatment of JMG in children are reported, for these reasons further studies are needed.

In the last decade, the applicability of robotic surgery has been demonstrated in many interventions, expanding the indications of minimally invasive surgery also to pediatrics. The aim of the study is to evaluate postoperative pain to demonstrate better control following robotic procedures compared to thoraco-laparoscopic surgery. An observational, retrospective, multicentre study was performed involving 204 children undergoing robot-assisted surgery and thoraco/laparoscopic surgery at the Istituto Giannina Gaslini in Genoa and the Siena University Hospital (2013-2017): 83 children underwent robotic-assisted surgery and 121 thoracic-laparoscopic surgery. Personal data and type of intervention were assessed, dividing the patients into four categories: thoracic, gastrointestinal, hepatobiliary and urological surgeries. We analyzed the anesthetic risk according to ASA classification by type of intervention, the type of anesthesia used, the anesthetic drugs used during surgery and in the postoperative period. Both the problems that occurred during the procedures and the number of interventions converted into open during robotic surgery and laparoscopic thoracic surgery were analyzed. Pain was measured on the 1st, 2nd and 3rd day (FLACC or NRS scales). By comparing the two groups (robotics-non-robotics), the analysis shows that postoperative pain does not change with the chosen approach, but always maintains very low values, typical of minimally invasive surgery. The pain score is significantly higher in patients undergoing thoracic surgery, either robotic or thoracoscopic, compared to those undergoing gastrointestinal surgery (P corrected according to Bonferroni: 0.0006) and those undergoing urological intervention (P corrected according to Bonferroni: 0.04). In conclusion, no significant change in the intensity of postoperative pain between the two groups was found, while it is seen that the pain in patients undergoing thoracic interventions (robotic/thoracoscopic) is more intense than that reported for other types of interventions.

Lymphangioma accounts for 5% of benign pediatric tumors and less than 1% is located in the abdomen. Indeed mesenteric cystic lymphangioma is a rare benign abdominal mass and its pathogenesis is still unknown. Mesenteric cystic lymphangioma is often diagnosed incidentally. Nevertheless, in some cases its clinical presentation can mimic several common surgical pathologies. Here we describe a case of mesenteric cystic lymphangioma mimicking an ileo-colic intussusception.

An association between malrotation and congenital duodenal webbing is rare. We present our experience with four patients at two centers, and a review of published reports. There are currently 94 reported cases of duodenal pathology associated with malrotation. However, only 15 of the 94 cases (15.9%) include patients with malrotation and a duodenal web. We suggest that nonbilious vomiting in a child must prompt the surgeon to consider duodenal pathology even in the presence of malrotation.

Torsion of an epididymal cyst is an extremely rare cause of acute scrotum in children and in young boys. Its reported incidence is 5-20%. The treatment is usually conservative. Many cases (up to 60%) regress spontaneously, especially if below 3 cm. Few cases have been reported in Literature (7 cases/2018). We add our patient as eighth case. He was a 13-year-old boy who was admitted for acute scrotum. Ultrasound excluded torsion of the testis and he was managed for 5 day conservatively. Based on clinical history and physical exam, we decided to perform a prompt surgery that revealed a torsion of epididymal cyst that was confirmed by histological exam.

Background Urethral duplication associated with epispadias is a rare malformation. Few cases are described in Literature. We report the experience of two centers to add to the literature. Methods A retrospective study was conducted in two Italian Centers. All patients with urethral duplication associated with epispadias, treated from 1997 to 2017 were included. The preoperative work-up included renal-urinary ultrasonography and voiding cystourethrogram. All patients underwent surgery according to the Mitchell-Caione technique. Cosmetic result, urinary continence and satisfaction degree of patients at the last follow-up were evaluated as outcomes. Six male patients with urethral duplication in epispadias were included. Two patients presented penile epispadias and four penopubic epispadias. Only one patient had urinary incontinence as presenting symptomatology. The diagnosis of urethral duplication was accidental during preoperative evaluation in the remaining five patients. Results At last follow-up (mean 8.3 years) all patients but one presented good cosmetic result, one patient presented mild stress urinary incontinence, one presented nocturnal enuresis. The physical genital appearance was improved in all patients. Urethral duplication in association with epispadias is a rare urogenital abnormality. No classification is universally accepted. Conclusions Based on our experience, we believe that the presence of any duplication should be carefully searched during surgery for male epispadias.

Background: Congenital pouch colon (CPC) is an unusual malformation associated with anorectal malformations (ARMs) that are seen especially in Asia. The aim of this study was to analyse our series of CPC associated with ARM in our centre and report our experience based on the rarity of pathology. Materials and Methods: This is a retrospective study conducted at the Department of Paediatric Surgery in North Iraq. We identified patients from a prospectively kept database, including all patients managed between 1997 and 2014. Results: In total, 17 patients (3 females and 14 males) were included; all had CPC and high ARM; male:female ratio was 5.6:1. Two females had colo-vestibular fistula, 1 had a colo-cloacal fistula, all males had imperforate anus with colovesical fistula. Pre-operative diagnosis of CPC was made in eight patients (47%). Four patients (23.5%) had an incomplete pouch colon (Type III and IV), and 13 (76%) had complete pouch colon (Type I and II). All patients were managed with staged surgery. Mortality rate was 17.6% (3/17). Conclusions: CPC associated with ARM can be defined as 'Asian' complex malformation. Few cases are reported in Literature from Europe and USA. However, it is known that it is ever more frequent the collaboration between Asian and European surgeons (as in our study), so the suspicion should be considered in all patient high ARM who come from Asian region. We reviewed literature and report our experience of 15 years, after a retrospectively analysis, to share it and add our data to their reported.

Prune-belly syndrome is a rare congenital disorder characterized by three major features: deficient abdominal wall musculature, urinary tract anomalies, and bilateral cryptorchidism in males. Incidence is estimated between 1/30,000 and 1/50,000 live births and the 3–5% of known cases are females. The exact pathogenesis of prune-belly syndrome is not clearly known as yet. Three major theories are known, but none of them have universal acceptance because none completely explains the whole constellation of findings in the syndrome. No specific gene defect has been identified for PBS. Many authors tried to formulate classification systems, but the considered classification system to date is by Woodard. The main goal of treatment of patients with prune-belly syndrome is to preserve renal function. The prognosis and the postnatal management of these patients, indeed, are closely related to it. The spectrum of therapeutic possibilities range from a “wait and see” approach to immediate or delayed urologic surgery.

Purpose To evaluate and compare the feasibility and short-term results of laparoscopic and robotic total oesophago-gastric dissociation (TOGD) with a Roux-en-Y oesophago-jejunostomy. Minimal invasive surgery has multiple advantages in neurologically impaired patients. Robotic approach has overcome disadvantages linked to laparoscopy, in particular, referring to the surgeon fatigue. Methods A retrospective study comparing five laparoscopic and five robotic TOGD was conducted between February and October 2016 in Giannina Gaslini Children's Hospital and Section of Pediatric Surgery of Siena. Neurologically impaired children scheduled for TOGD were included. Age, sex, weight, symptomatology, presence of epilepsy, and preoperative X-ray contrast were considered. Operative time, hospital stay, postoperative complications, redo surgery, nutrition rehabilitation, and X-ray contrast study after 5 days and after 1 month from the intervention were recorded. Results In our series, there were no intraoperative complications, no conversions to open surgery, and no vagal lesions. In two of five robotic cases, a pyloroplasty was necessary. The median operative time was statistically longer in the robotic group. One dehiscence in the robotic group was recorded, and no dumping episodes occurred. No statistical differences in terms of complications were detected. Conclusion TOGD is feasible both with laparoscopic and robotic-assisted surgery with similar results. Robotic approach is considered feasible. At the same time, high laparoscopic skills allow to reach the same results as robotic approach with shorter operative time.

We present a very rare case of gastric duplication treated with complete excision with two surgical procedures. We decided to report our case to share our experience that confirm the difficult of preoperative/intraoperative diagnosis of gastric duplication in a pediatric patient. Finally we reviewed the literature to date.

Persistent pulmonary interstitial emphysema (PPIE) is a rare condition that occurs in both preterm and term infants. It is thought to arise from a disruption of the basement membrane of the alveolar wall allowing air entry into the interstitial space. The characteristic CT scan appearance of PPIE can be used to differentiate it from other congenital cystic lesions that may present similarly. The management of infants suffering from diffuse persistent interstitial pulmonary emphysema varies according to severity and stability of the patient, being either conservative treatment or aggressive surgical treatment by pneumonectomy. We report a case of an unstable patient with diffuse persistent interstitial pulmonary emphysema successfully treated by lobectomy as a form of conservative surgical approach.

Background Esophageal replacement in children is an option that is confined to very few situations including long-gap esophageal atresia and esophageal strictures unresponsive to other therapies (peptic or caustic ingestion). The purpose of our work was to describe the experience of gastric transposition in three Italian centers. Methods This is a retrospective study. The data were extrapolated from a prospective database. We included all patients who had undergone gastric transposition in the last 15 years. Results In the 15-year period, eight infants and children (3 males and 5 females) underwent gastric transposition for esophageal replacement. Six patients had long-gap esophageal atresia, and two had caustic esophageal stenosis. There were no deaths in the series. Three patients had an early postoperative complication: two had a self-limited salivary fistula at three weeks, and one (a patient with jejunostomy) had a jejunal perforation treated surgically. One late complication, anastomotic stricture, was recorded that required two endoscopic dilatations. The median follow-up was 60 months (range: 18-144 months). At final clinical follow-up, six patients had no eating problems, and two patients had some difficulties with eating (jejunostomy in situ), but they underwent logopedic therapy with improved outcomes. All patients had an increase in body weight and height postoperatively. Conclusion Our small study reports the clinical experience of three Italian centers in which gastric transposition was performed with excellent results, both in terms of surgical technique (simplicity, reproducibility, complication rate) and clinical follow-up (good oral feeding of young patients, normal social life and regular growth curves).

Background: Phimosis is a condition in which the foreskin cannot be portrayed on the glans. It is a physiological and common condition in the pediatric age. The pathological form derives from an inflammatory or traumatic lesion. Circumcision is the most common surgical treatment of phimosis but it is a controversial practice, especially in occidental world. Methods: We enrolled 61 patients with pathological phimosis (22/balanoposthitis, 18/painful erection, 21/ urinary discomfort) between 2015–2017. Results: All patients underwent preputialplasty. Conclusions: Various alternatives to circumcision have been described, as manual retraction therapy, topical steroid therapy, and many types of preputialplasty. We report our technique.

Summary Introduction Botulinum toxin-A (BtA) has been used for refractory idiopathic overactive bladder (IOAB) in children. Data on the optimum dose success rates, duration of effect, complications and medium-term outcomes are limited. This study aims to analyse the authors' experience to provide medium-term results of BtA in symptomatic refractory patients. Materials and methods Patients with refractory IOAB who were treated with BtA (Botox®) were retrospectively analysed. All patients had urodynamic study before treating with BtA. Group A had low-dose BtA (LDBtA) at 5 units/kg (maximum 150 units), and Group B had high-dose BtA (HDBtA) at 10 units/kg (maximum 300 Units). Post-BtA clinical response, functional bladder capacity (FBC) and postvoid residual (PVR) were assessed in addition to the duration of response. Results Thirty-nine patients, 11 male and 28 female, were analysed. Forty-six percentage had symptom improvement (73% of males and 36% of females [P = 0.072, ns]). The difference in response rates between LDBtA and HDBtA was not statistically significant (P = 0.684). Increase in total bladder capacity (TBC) was greater in those given HDBtA (P ≤ 0.001), but the increase in FBC was not different between the groups, due to greater PVRs in the HDBtA group. Nine patients (23%) developed UTI; however, six of these patients suffered with UTI pre-BtA as well. Only three were asymptomatic after a single treatment with BtA. The remainder required further BtA or oral anticholinergic therapy. At a median follow-up of 35.4 months (interquartile range [IQR] 25.2–46.6), 12 (31%) were asymptomatic and off all therapy, 18 (46%) were still symptomatic despite therapy and 9 (23%) had their symptoms controlled on continuing treatment. Discussion and conclusions Botulinum toxin-A improves symptoms in 46% of children after the first injection in refractory IOAB. Although HDBtA resulted in greater increase in bladder capacity, it conferred no advantage in terms of success rate or duration of response. Five units/kg may be an optimum dose to use as a first treatment with the understanding that some patients will require a higher dose. And, there will be a cohort of patients who need a dose lower than 5 units/kg. A higher dose is more likely to lead to PVR leading to urine stasis and UTIs. The success of BtA only lasts until its effect wears off, and the majority of this cohort (36/39) required continuing treatment with repeat BtA or anticholinergic agents. However, it remains a useful option in patients who are intolerant or unresponsive to anticholinergic medication with symptomatic resolution in 30% at medium-term follow-up.

Duplications of the alimentary tract are rare malformations, and ileum is the most involved intestinal tract. During fetal life, they are usually occasional findings and may be asymptomatic until adulthood. We present the clinical case of volvulus on ileal cystic duplication diagnosed by ultrasound during prenatal follow-up. Case report: Diagnosis of cystic ileal duplication was made by ultrasound at our center at 23 weeks of gestational age, which was confirmed with fetal MRI. During follow-up, at 36 + 4 weeks, the presence of dilated loops with reduction of peristalsis was shown by ultrasound, so that, despite stable fetal parameters, an emergency caesarean delivery was programmed for suspected volvulus. After being stabilized, the patient underwent to laparotomy that revealed ileal volvulus at 2 cm from the ileo-cecal valve on a cystic duplication. Cyst and necrotic loop (10 cm) was resected and was performed an anastomosis. Patient started feeding on VII post-operative day, and was discharged on the X day. Patient is on follow up and present good conditions. Discussion: Diagnosis of intestinal cystic mass in prenatal period requires a close follow-up because the risk of a volvulus. According to the literature, even in the presence of stable fetal parameters, the presence of dilated loops and the absence of peristalsis are signs that must suspect the presence of a mechanical occlusion for which timely treatment is necessary to reduce mortality and morbidity.

The management of choledochal cysts has evolved during the last 3 decades. Laparoscopic surgery has revolutionized the treatment of choledochal cyst (CC). We report our case, 2-year old female, in which total excision of cyst and Roux-en-Y hepaticoenterostomy is done by laparoscopic approach. In the hands of experts, laparoscopic excision of the CC is safe and effective approach. This is our first experience and our outcome has been good to a follow-up of 6 months. In our opinion, laparoscopic surgery is a safe treatment of choledochal cyst with less postoperative morbidity, a shorter length of stay and a lower blood loss when compared with open approach. Laparoscopic surgery may become the first choice procedure for choledochal cyst.

Introduction To study the impact on adult’s fertility of serum inhibin B levels in adolescent patients with idiopathic varicocele after minimally invasive surgical correction and to compare fluctuation of pituitary-testis hormonal values and testicular volumes. Materials and Methods: A case-control study was carried out on a group adolescent patients (n=60) affected by idiopathic left varicocele (group V) and compared with control adolescents (n=40) in the Paediatric Surgery Section of Siena (from June 1993 till September 2013). Inhibin B levels and testicular volume before (T0) and after at 6 and 12 months from surgery (T1 and T2) were evaluated. Results: A positive correlation between testicular growth at T1 and T2 (P

Background Necrotizing enterocolitis (NEC) is the most common surgical emergency in newborns and it is still a leading cause of death despite the improvements reached in the management of the critically ill neonate. The purpose of this study was to evaluate risk factors, surgical treatments and outcome of surgical NEC. Methods We retrospectively evaluated a multicentric group of 184 patients with surgical NEC over a period of 5 years (2008-2012). Indications to operation were modified NEC Bell stages IIIA or IIIB. The main outcome was measured in terms of survival and postsurgical complications. Results Data on 184 patients who had a surgical NEC were collected. The majority of patients (153) had a primary laparotomy (83%); 10 patients had peritoneal drainage insertion alone (5%) and 21 patients had peritoneal drainage followed by laparotomy (12%). Overall mortality was 28%. Patients with lower gestational age (P=0.001), lower birth weight (P=0.001), more extensive intestinal involvement (P=0.002) and cardiac diseases (P=0.012) had a significantly higher incidence of mortality. There was no statistically significant association between free abdominal air on the X-ray and mortality (P=0.407). Mortality in the drainage group was 60%, in the laparotomy group and drainage followed by laparotomy group was of 23-24% (P=0.043). There was a high incidence of stenosis (28%) in the drainage group (P=0.002). On multivariable regression, lower birth weight, feeding, bradycardia-desaturation and extent of bowel involvement were independent predictors of mortality. Conclusions Laparotomy was the most frequent method of treatment (83%). Primary laparotomy and drainage with laparotomy groups had similar mortalities (23-24%), while the drainage alone treatment cohort was associated with the highest mortality (60%) with statistical value (P=0.043). Consequently laparotomy is highly protective in terms of survival rate. Stenosis seemed to be statistically associated with drainage. These findings could discourage the use of peritoneal drainage versus a primary laparotomy whenever the clinical conditions of patients allow this procedure.

Background: Around 70% of children with neurodisability (ND) present pharyngeal neuromuscular incoordination and severe gastroesophageal reflux disease (GORD). Methods: This is a pilot study with the Robotic-assisted minimally invasive total esophagogastric dissociation (TOGD). Results: We included 4 patients, 2 males and 2 females, with ND and severe GORD refractory to medical treatment. Conclusions: Pharmacological management of GORD is often unsuccessful and antireflux surgery is common, but it has a high failure rate with symptom recurrence, requiring re-do surgery. TOGD is a good option for these patients.
