Purpose To quantify our experience with and assess the literature on diagnosis and management of isolated fallopian tube torsion (IFTT) with hydrosalpinx (HSX) in children. Methods A PubMed search was performed on pediatric cases of IFTT with HSX to provide a comprehensive review analyzing details and management of this association, focusing on the problem of fertility preservation. Results In addition to our 3 cases, 17 patients of pediatric IFTT associated with HSX were identified, for a total of 21 cases (median age 12.2 years). Menarchal status was present in 10/13 (76.9%); blood tests were reported in 9/20 (42%) showing leucocytosis in 7/9 (75%). Ultrasonography was performed in all cases except one. Laparoscopy was the surgical approach in 84.6% of the reported cases. The torsion was to the right in 36.8%, and to the left in 63.2% of the cases. In one case the torsion was bilateral and asynchronous. Performed procedures were salpingectomy (52.4%) and partial salpingectomy (14.3%); conservative management was reported in 33.3% of the cases. Conclusions The literature describes different management techniques. Salpingectomy is the most frequently performed procedure but recently conservative management seems to be increasingly applied. A long-term study is necessary to define the most effective treatment for the preservation of future fertility in pediatric patients. Type of study Treatment study (Retrospective Study): LEVEL IV.

Objective: The aim of this study was to review the English literature about a rare condition such as symptomatic mesodiverticular bands (MDBs) in children. Background: The MDB is an embryologic remnant of the vitelline circulation, which carries the arterial supply to Meckel’s diverticulum. In the event of an error of involution, an arterial band persists and extends from the mesentery to the apex of the antimesenteric diverticulum. This can create a snare-like opening through which bowel loops may herniate and become obstructed. This type of internal hernia is a very rare and often overlooked cause of small bowel obstruction. Materials and methods: A computer-assisted (PubMed) search of the literature to identify all cases of symptomatic MDB reported in English with patients’ age ranging from 0 to 14 years was performed. Results: Eight cases of symptomatic MBD in pediatric age (0–14 years) were found in the literature in the last 50 years. Male : female ratio was 3 : 1. The age of onset ranged from 10 days to 12 years. All cases reported an intestinal occlusion as clinical picture. Internal hernia was the cause of the obstruction in six cases, whereas in two patients the occlusion was due to a direct compression. All patients were approached with emergent laparotomy except one case of laparoscopic approach. Conclusion: MDB causing internal hernia is a very rare event but it should be kept in mind concerning patients with the presentation of small bowel obstruction when early surgery is important to prevent strangulation, gangrene of the bowel, and to avoid dramatic events.

Infantile hypertrophic pyloric stenosis (IHPS) is a common surgical cause of gastric outlet obstruction among infants, characterized by elongation and narrowing of pyloric canal due to hypertrophy of pyloric muscle. IHPS is characterized by a progressive gastric outlet obstruction causing non-bilious projectile vomiting. Although the etiology is unclear, the pyloric muscle thickens abnormally in time and causes the obstruction of gastric outlet. Depending on the duration of symptoms, dehydration and hypokalemic hypochloremic metabolic alkalosis may occur. Physical examination and whether necessary ultrasonography may be enough for diagnosis of IHPS, and its standardized operative intervention is pyloromyotomy. In this chapter, other pyloric affections were also described.

Background Recurrent ipsilateral ovarian torsion at pediatric age is a rare event. Different surgical techniques for its prevention are available. We present a case of recurrent ipsilateral ovarian torsion in a prepubertal girl and we reviewed the literature about the management of this condition. Case A 6-year-old girl presented with right ovarian torsion and underwent a laparoscopic untwisting. Nine months later an ipsilateral recurrence occurred. Laparoscopic untwisting and right-sided oophoropexy with plication to the round ligament was performed. Summary and Conclusion In addition to our presented case, four cases of recurrent ipsilateral ovarian torsion in pediatric patients were identified in the literature. The few available reports in the pediatric literature show different management techniques. A long-term study is necessary to define the most effective treatment.

Objectives Management for urachal anomalies (UAs) is controversial. Although traditional treatment of UAs has been surgical excision, recent literature report also a conservative approach. We reviewed our experience to define the role of laparoscopy in the management of UAs in children. Patients and methods From July 2005 to July 2015, 23 children underwent 24 interventions for the treatment of UAs. In four patients, the technique was a laparoscopicassisted removal of the anomaly, in two patients a laparoscopic-assisted drainage of an urachal abscess, and a pure laparoscopic technique was started in 17 patients. Results Laparoscopic-assisted removal of the UAs was achieved in five cases. In two cases a laparoscopic-assisted drainage of an urachal abscess was performed. The remaining patients were treated by pure laparoscopic technique. Operative or postoperative complications did not occur. Follow-up ranged from 6 months to 10 years and 6 months. Conclusion The pure laparoscopic approach to UAs appears safe and effective in most urachal remnants. Laparoscopic-assisted excision is an alternative approach that is easier to perform in infants. The decision to remove the UAs must be taken after an accurate informed consent of the parents, especially in cases of asymptomatic anomalies.

Objective The aim of this study was to describe a new case of autoamputated adnexa in a neonate treated with laparoscopy and to present a review of the literature as regards laparoscopic management of the autoamputated adnexa in neonates and infants. Summary background data Laparoscopic surgery has become an accepted modality internationally in neonates and infants. We analyzed technical details of laparoscopic procedures adopted in the literature for this rare condition. Materials and methods A literature review was performed to identify additional cases of autoamputated adnexa treated laparoscopically. Cases were limited to the English language and to those affecting girls under 1 year of age. Results In addition to our presented case, 12 cases of autoamputated adnexa in patients less than 1 year of age treated laparoscopically were identified in the literature. Surgical intervention was planned for increasing size of cysts, for no signs of reduction, or for complex cysts, except in one case for suspicion of enteric duplication. The number of ports for the removal varies from one to three based on different authors. The operative port size ranged from 3 to 5 mm. Camera size was 5mm for all authors when reported but only five authors reported the size of the umbilical port. Conclusion Although laparoscopic removal of autoamputated adnexa can be successfully accomplished in newborns and infants, 50% of autoamputated adnexa are still treated with laparotomy. Our review revealed the necessity of at least two ports for the identification and removal of the adnexa using the laparoscopic-assisted technique, whereas three trocars in the presence of tenacious adhesions.

Objective The aim of this paper is to present the results of a 6-year experience with a laparoscopic-assisted approach to infantile hypertrophic pyloric stenosis (IHPS): the singleport, laparoscopic-assisted pyloromyotomy (SPLAP). Summary background data Ramstedt pyloromyotomy is the procedure of choice for IHPS; however, the best way to approach the pylorus is still debated. The recent literature reports many comparisons between various open and laparoscopic approaches. Here, we report our long-term result with a laparoscopic-assisted technique for IHPS. Materials and methods Thirty-eight infants underwent SPLAP. The approach to the abdominal cavity is performed through a right circumbilical incision and then a 10mm trocar is inserted. After the pneumoperitoneum is established, an operative telescope is introduced. Once the telescope is inserted, the pylorus is easily located and then grasped and exteriorized by the umbilical incision. At this point, conventional Ramstedt pyloromyotomy is performed. Once the pylorus is reintroduced into the abdomen, a new pneumoperitoneum is created to control mucosal integrity and hemostasis. Results In all 38 cases, adequate pyloromyotomy was performed in a good operative time, without any major intraoperative or postoperative complications, achieving excellent cosmetic results. Conclusion The feasibility of SPLAP found over these 6 years suggests that this procedure is an excellent alternative to open or laparoscopic pyloromyotomy.

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.

The objective of this article is to review the literature on a very rare association such as patent urachus and a patent omphalo–mesenteric duct in children. Partial or total failure of the obliteration of urachus gives rise to various anomalies, which can be diagnosed both in childhood and in adulthood. The omphalo–mesenteric duct remnants are the most common anomalies of the gastro-intestinal tract, often asymptomatic. The association of patent urachus and a patent omphalo–mesenteric duct in children is very rare. A computer-assisted (PubMed and Google Scholar) search of the pediatric literature to identify all cases of patent urachus and a patent omphalo–mesenteric duct association was performed. We found only eleven cases of the association of patent urachus and a patent omphalo– mesenteric duct in the pediatric literature. All cases except one were males. When reported, all children affected were full term. The clinical sign reported was umbilical spillage. In all cases was reported a lack of healing of the umbilical stump with different clinical pictures, except two cases. Treatments reported were application of silver nitrate, antibiotic cream, povidone iodine, and application of salves and plasters. Various diagnostic examinations were performed. In none of these patients was the possible association with PU and POMD suspected, but it was evidenced only during the surgical excision. The surgical approach was laparotomy in all cases. The association of patent urachus and a patent omphalo–mesenteric duct in children is very rare approached in all cases by laparotomy. This review underlines the importance of evaluating any persisting umbilical lesions without delay when conventional pharmacological therapy fails.

Rational: Patent urachus (PU) is due to an incomplete obliteration of the urachus, whereas patent omphalomesenteric duct (POMD) is due to an incomplete obliteration of the vitelline duct. These anomalies are very rarely associated with one another. We describe a case of a newborn with a PU associated with a POMD, who was diagnosed by an abdominal ultrasound (US) and laparoscopy, and managed with a minimally invasive excision. Patient concern: A 28-day-old male neonate was referred to our hospital to investigate a delay in umbilical healing, with blood-mucinous material spillage for 3 weeks prior to the referral. The baby had no symptoms and was in good general health. Diagnosis: After a thorough cleaning of the umbilical stump, a clear granuloma with a suspected fistula was evident under the seat of the ligature of the stump. An abdominal US examination revealed the formation of a full communication, starting below the umbilical stump and developing along the anterior abdominal wall that connected with the bladder dome. The US also revealed a tubular formation containing air, which was compatible with POMD, in the deepest portion of the same umbilical stump. Considering these findings, the rare diagnosis of a PU associated with a POMD duct was suspected. Interventions: The child was then hospitalized for an elective laparoscopy that confirmed the US picture, and a minimally invasive excision was performed. Outcome: The postoperative course was favorable and uneventful. Lessons: Our case underlines the importance of evaluating all persisting umbilical lesions without delay when conventional pharmacological therapies fail. Using a US as the first approach is valuable and should be supported by laparoscopy to confirm the diagnosis; a minimally invasive excision of the remnants appears to be an effective therapeutic approach.

Traumatic abdominal wall hernias (TAWHs) can be defined as a herniation through disrupted musculature and fascia associated with blunt trauma. They are seen in approximately 1% of patients with blunt abdominal trauma. Data on TAWH in the pediatric population are very limited and principally based on case reports and a few case series. Past reports have indicated that the presence of the "handlebar sign" confers an increased risk of internal injury. Concomitant internal injuries are reported with an incidence between 25% and 70%, and occult hernias may also occur and are usually detected only by abdominal computed tomography scan and ultrasonography. The treatment of TAWH consists in surgical exploration through closure of the defect. We describe 2 cases of TAWH due to blunt impact by bicycle handlebars that occurred in our department with a brief literature review. Our objectives are to describe the variable clinical presentations and management of these events. We hope to provide a useful tool for the clinician to increase early clinical suspicion and detection of this insidious injury.

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.

Objective The aim of this study was to analyze retrospectively the 9-year experience of a single institution in the use of the double cross flap technique to interpose a double dartos flap to protect the neourethra with the aim of preventing fistula formation. Patients and methods Between October 2005 and September 2014 a total of 127 children with distal and midshaft primary hypospadias underwent tubularized incised plate urethroplasty by means of a double dartos flap obtained with a double cross flap to protect the neourethra. A Foley catheter was left in situ for 7 days. Success was defined as no incidence of complications requiring reintervention, along with good cosmetic result. A questionnaire was administered to estimate parental satisfaction. Parents were asked to evaluate the cosmetic appearance of the penis as good, acceptable, bad, or indifferent. Results The patient age at the time of surgery ranged from 12 months to 10 years (median 39 months). Three patients exhibited fistula at follow-up (2.3%). In two patients a glandular dehiscence of the urethroplasty occurred (1.5%). Mild stenosis of the neomeatus occurred in three patients (2.3%). No penile iatrogenic rotation occurred. A ‘good’ cosmetic result was reported by 68.5% of parents, acceptable by 22.8%, bad by 3.9% and indifferent by 4.7% of parents as per the parental questionnaire. Conclusion The double cross flap technique is not the panacea to prevent fistula formation in hypospadias surgery. Nevertheless, it offers an unquestionable advantage in terms of avoidance of fistula formation. The experience and skills of the surgeon performing urethroplasty remain the mainstay for best results.

Background: Reoperation for failed hypospadias has been considered to be seriously problematic. The dense fibrotic tissue causes difficulties in wound healing and increases the rate of complications. The tubularised incised-plate urethroplasty (TIPU) method has become a preferred method for all varieties of hypospadias in the past decade. However, fistulas are still one of the most common complications of this technique. The aim of this paper was to present the preliminary results of TIPU procedure with double de-epithelised dartos flaps in failed hypospadias repair. Materials and Methods: All patients were treated between January 2009 and August 2010 by the same procedure, utilising TIPU with double de-epithelised dartos flaps. Vascularised ventral dartos flaps harvested from each side of the penis with their vascular supply were transposed to cover the suture line by wrapping them from either side of the penis. Results: There were 21 boys with failed hypospadias: 20 had previously undergone TIPU, and one Koyanagi repair. Patients presented with very large fi stulas in four and dehiscence in 17. Repair of the failed hypospadias using TIPU with double de-epithelised dartos flaps was quite successful, with no fistula recurrence or dehiscence observed. Conclusion: The preliminary results showed that TIPU with double de-epithelised dartos flaps is a useful method of successfully repairing failed hypospadias.

OBJECTIVES • To evaluate urethrocutaneous fistula repair after urethroplasty using n-butyl cyanoacrylate (NBCA) in an outpatient setting. • To compare results of application of NBCA in 'early' and long-standing fistulae. PATIENTS AND METHODS • From January 2003 to December 2006, 13 children (mean age 36 months) were treated in our Outpatient Department for urethrocutaneous fistula, which occurred after hypospadias repair. • We analysed the data dividing the patients in two groups: group A comprised six children (mean age 22.6 months) that developed a fistula within 2-3 days of catheter removal after urethroplasty ('early' fistula) and group B comprised seven children (mean age 42.6 months) with long-standing fistulae. • In all patients, a multilayer of NBCA was applied, attaching the edges of the fistula taking care to perform a scarification of the edges of the fistula in patients in group B before the application of the glue. RESULTS • Four patients in group A and three patients in group B had definitive fistula repair (seven of 13), and six of the 13 had fistula recurrence. • Fistulae of ≤ 2 mm were more easily repaired than fistulae of > 2 mm (five of seven vs two of six). • Fistulae that tended to recover were those that responded to the first applications. CONCLUSIONS • In this experience the use of NBCA as a minimally invasive treatment for fistula repair gave good results for repairing fistulae. • These preliminary results encourage the use of NBCA as a first non-surgical attempt to repair urethrocutaneous fistulae especially if the fistula is ≤2 mm. • The failure of this procedure does not compromise a possible subsequent surgical repair.

The authors report their experience in laparoscopic repair of inguinal hernias in children. From May 2010 to November 2013, 122 patients with inguinal hernia underwent laparoscopic herniorrhaphy (92 males and 30 females). Telescope used was 5 mm, while trocars for the operative instruments were 3 or 2 mm. After introducing the camera at the umbilical level and trocars in triangulation, a 4-0 nonabsorbable monofilament suture was inserted directly through the abdominal wall. The internal inguinal ring was then closed by N or double N suture. All operations were performed in one-day surgery setting. In the case of association of inguinal and umbilical hernia an original technique was performed for positioning and fixing the umbilical trocar and for the primary closure of the abdominal wall defect. The postoperative follow-up consisted of outpatient visits at 1 week and 1, 3, and 6 months. The mean age of patients was 38.5 months. Of all patients, 26 were also suffering from umbilical hernia (19 males and 7 females). A total of 160 herniorrhaphies were performed; 84 were unilateral (66 inguinal hernia, 18 inguinal hernia associated with umbilical hernia), 38 bilateral (30 inguinal hernia, 8 inguinal hernia associated with umbilical hernia). Nine of 122 patients (6 males and 3 females) were operated in emergency for incarcerated hernia. A pre-operative diagnosis of unilateral inguinal hernia was performed in 106 cases. Of these patients, laparoscopy revealed a controlateral open internal inguinal ring in 22 cases (20.7%). The mean operative time was 29.9±15.9 min for the monolateral herniorrhaphies, while in case of bilateral repair the mean operative time was 41.5±10.4 min. The mean operative time for the repair of unilateral inguinal hernia associated with umbilical hernia was 30.1±7.4 while for the correction of bilateral inguinal hernia associated with umbilical hernia 39.5±10.6 min. There were 3 recurrences (1.8%): 2 cases in unilateral repair and 1 case a unilateral recurrence in a bilateral repair. No other complications were seen. Laparoscopic repair of inguinal hernia in children performed in this experience resulted a safe and effective procedure.

Background Our study aims at disclosing epidemiology and most relevant clinical features of esophageal atresia (EA) pointing to a model of multicentre collaboration. Methods A detailed questionnaire was sent to all Italian Units of pediatric surgery in order to collect data of patients born with EA between January and December 2012. The results were crosschecked by matching date and place of birth of the patients with those of diagnosis-related group provided by the Italian Ministry of Health (MOH). Results A total of 146 questionnaires were returned plus a further 32 patients reported in the MOH database. Basing on a total of 178 patients with EA born in Italy in 2012, the incidence of EA was calculated in 3.33 per 10,000 live births. Antenatal diagnosis was suspected in 29.5% patients. 55.5% showed associated anomalies. The most common type of EA was Gross type C (89%). Postoperative complications occurred in 37% of type C EA and 100% of type A EA. A 9.5% mortality rate was reported. Conclusions This is the first Italian cross-sectional nationwide survey on EA. We can now develop shared guidelines and provide more reliable prognostic expectations for our patients.

We report a case of a 5-year-old boy with acute abdomen following an upper airways infection who developed Meckel’s diverticulum perforation secondary to group A β-hemolytic streptococcus and its successful treatment by a laparoscopic-assisted intervention. To the best of our knowledge, such an event has never been reported previously. Keywords: group A β-hemolytic streptococcus, intestinal perforation, Meckel’s diverticulum

Urachal remnants (URs) are manifestations of an incomplete regression of the urachus; therefore, there may be different types of remnants such as cyst, sinus tract, diverticulum or patent urachus. The clinical presentation of a urachal anomaly includes umbilical discharge, lower abdominal pain and urinary tract infection, although a UR may also be asymptomatic. We present the case of a 2.5-year-old girl who presented with abdominal pain, stranguria and massive pyuria in which a giant infected UR was found. The diagnosis was made using abdominal MRI. The child was subjected to laparoscopic-assisted drainage and had an uneventful postoperative course. Keywords : differential diagnosis, infected urachal remnant, laparoscopy, pyuria

The authors report their preliminary experience in laparoscopic repair of associated inguinal and umbilical hernias in children.Twenty-six patients affected by the association of inguinal and umbilical hernia with an umbilical defect larger than 5 mm underwent a laparoscopic procedure. A 5-mm trocar was placed through the umbilical defect for the optic. To fix the trocar to avoid loss of carboperitoneum, we fashioned and tightened a purse-string non-absorbable suture with a sliding knot around the defect. In this manner, we ensured the trocar, fixing it and avoiding any loss of CO2, proceeding safely to the laparoscopic IH repair, by means of two additional 3 mm operative trocars. At the end of the inguinal herniorrhaphy, the previously fashioned purse-string suture was tightened to repair the umbilical defect.The mean operative time for the repair of associated inguinal and umbilical hernias was 30.1 ± 7.4 min in cases of unilateral inguinal hernia and 39.5 ± 10.6 for bilateral inguinal hernia. Follow-up ranged from 8 to 32 months. Neither intra- nor post-operative complications nor recurrences were seen.This small sample suggests that this simple method is safe, effective and might be useful for pediatric surgeons performing laparoscopic repair for inguinal hernia in presence of an associated UH with a statistically significant decrease of operative time.

To evaluate laparoscopic treatment of symptomatic urachal remnants in children, the authors review their experience analyzing different approaches and results obtained in a 8-year period.From July 2005 to September 2013, 12 children underwent 13 interventions for treatment of symptomatic urachal remnants. In four patients, the technique was a laparoscopic-assisted removal of the remnant, in two patients, a laparoscopic-assisted drainage of an urachal abscess, and in seven patients, a laparoscopic excision of the remnant. One patient underwent a double intervention-laparoscopic drainage of an infected urachal remnant and its delayed laparoscopic excision.The laparoscopic-assisted removal of the urachal remnant was performed in two cases of infected urachal sinus, in one case of symptomatic sinus, and in one cases of infected urachal cyst. The laparoscopic-assisted drainage of urachal abscesses was performed in two patients: In one patient, the abscess was because of an infected sinus while in the other patient, the abscess was caused by an infected cyst. Of the seven patients treated with pure laparoscopic technique, one had a symptomatic sinus, another had an association between a symptomatic urachal sinus and an urachal cyst, and five patients had a symptomatic urachal cyst. In all cases, intraoperative or postoperative complications and recurrences did not occur, and the cosmetic results were good. Follow-up ranged from 6 months to 8 years and 8 months.Laparoscopic surgery for symptomatic urachal remnants is safe and reliable in cases of drainage of urachal abscess and in cases of excision of the remnant. Laparoscopy allows a radical excision of the remnants with all the advantages of this procedure. In case of conversion, laparoscopic-assisted technique with minimal incision could be a good alternative to open surgery.

Human infections caused by Dirofilaria repens have been reported in many areas of the world. We describe a case of a 3-year-old child with an intrascrotal mass caused by D repens mimicking an acute scrotum. This represents the first case of scrotal dirofilariasis described in pediatric age with such an unusual presentation.

Objectives This study aimed to review the literature about symptomatic Meckel's diverticulum (MD) in the neonatal period with 2 additional uncommon cases. Methods The authors describe 2 interesting neonatal cases of symptomatic MD and analyze the literature on this topic, with particular reference to the prevalence of sex, age at presentation, most common signs and symptoms, treatment, histology, associated anomalies, and outcome. Results The first patient was a term newborn with bowel obstruction by a pseudocystic MD. The second patient was a preterm infant with double perforation of the MD and ileum. Literature search for published case reports and case series on this topic reveals only 18 cases of neonatal symptomatic MD. Males are more frequently involved than females, and even preterm infants may be affected. Bowel obstruction (58.3%) and pneumoperitoneum (33.3%) are the most frequent clinical manifestation. Acute inflammation of the MD is the prominent histopathological finding (75%), although it does not seem to be related with the presence of heterotopic tissue within the MD. Surgical treatment is essential. The association of neonatal symptomatic MD with other anomalies is exceptional but is otherwise life threatening despite surgery. Conclusions Bowel obstruction and pneumoperitoneum are the most frequent clinical manifestations of symptomatic MD in the newborn. Surgery is required for a definitive diagnosis and successful outcome.

To evaluate the learning curve of pediatric laparoscopic herniorrhaphy (LH), the authors report a retrospective analysis comparing results obtained with this technique and the traditional herniotomy to determine how many procedures are necessary to obtain the results described in the literature.From May 2008 to February 2012, a total of 140 patients (110 boys and 30 girls) with uncomplicated inguinal hernia (IH) consecutively underwent surgery. Patients were divided in two groups: The "Open" group of 83 patients (M:F 64:19) with a mean age of 33.2 months who were operated on with traditional herniotomy and the "Lap" group of 57 patients (M:F 46:11) with a mean age of 34.5 months who were operated on with LH. Operative time and complications of the techniques were analyzed statistically.In the Open group, the mean operative time for monolateral repair was 35.4 ± 17.7 minutes compared with the Lap group time of 29.9 ± 15.9 minutes; for bilateral repair, the mean operative time for the Open group was 56.2 ± 19.3 minutes compared with the Lap group time of 41.5 ± 10.4 minutes. The analysis shows a shorter operative time for the laparoscopic repair for both monolateral (P=0.73) and bilateral (P=0.0001) hernia. Recurrences occurred in one (0.9%) patient in the Open group and in two (2.7%) patients in the Lap group (P=0.577).This experience shows that LH is a reliable technique. Retrospective analysis revealed a shorter mean operative time for the laparoscopic intervention both for monolateral and bilateral IH repair. Recurrences in the Lap group occurred in the first 10 patients treated, and the mean operative time was reached in 20 monolateral LHs and after 15 bilateral herniorrhaphies. From this analysis, the learning curve for the LH needs a minimum of 20 procedures.

Dog bite injuries are common in children and represent an important health-care problem. Most dog bite injuries involve the face or an extremity. Victims tend to seek medical care quickly. Dog bites to the external genitalia are rarely reported, but they potentially result in morbidity if improperly managed. Morbidity is also directly related to the severity of initial wound. Guidelines for the management of dog bites include irrigation, débridment, antibiotic therapy, consideration of tetanus and rabies immunisation and suture of wounds or surgical reconstruction. Literature review was conducted and focused to analyze the management of dog bite lesions involving external genitalia.Key words: Children, dog bite, genitalia, management

• To evaluate urethrocutaneous fistula repair after urethroplasty using n-butyl cyanoacrylate (NBCA) in an outpatient setting. • To compare results of application of NBCA in 'early' and long-standing fistulae.• From January 2003 to December 2006, 13 children (mean age 36 months) were treated in our Outpatient Department for urethrocutaneous fistula, which occurred after hypospadias repair. • We analysed the data dividing the patients in two groups: group A comprised six children (mean age 22.6 months) that developed a fistula within 2-3 days of catheter removal after urethroplasty ('early' fistula) and group B comprised seven children (mean age 42.6 months) with long-standing fistulae. • In all patients, a multilayer of NBCA was applied, attaching the edges of the fistula taking care to perform a scarification of the edges of the fistula in patients in group B before the application of the glue.• Four patients in group A and three patients in group B had definitive fistula repair (seven of 13), and six of the 13 had fistula recurrence. • Fistulae of ≤ 2 mm were more easily repaired than fistulae of2 mm (five of seven vs two of six). • Fistulae that tended to recover were those that responded to the first applications.• In this experience the use of NBCA as a minimally invasive treatment for fistula repair gave good results for repairing fistulae. • These preliminary results encourage the use of NBCA as a first non-surgical attempt to repair urethrocutaneous fistulae especially if the fistula is ≤2 mm. • The failure of this procedure does not compromise a possible subsequent surgical repair.

Ramstedt pyloromyotomy is still the procedure of choice for infantile hypertrophic pyloric stenosis; however, the best way to approach the pylorus is debated. Recent literature reports many comparisons between various open approaches and laparoscopic one. The purpose of this preliminary experience is to show a new approach to infantile hypertrophic pyloric stenosis: single-port, laparoscopic-assisted pyloromyotomy. Nineteen infants underwent single-port laparoscopic-assisted pyloromyotomy. The approach to the abdominal cavity is performed through a right circumbilical incision, and then a 12-mm trocar is inserted. After the pneumoperitoneum is established, an operative telescope is introduced. Once the telescope is inserted, the pylorus is easily located, and then grasped and exteriorized via the umbilical incision. At this point, conventional Ramstedt pyloromyotomy is performed. Once the pylorus is reintroduced in the abdomen, a new pneumoperitoneum is created to control mucosal integrity and hemostasis. A retrospective statistical analysis was performed to compare patients who underwent this technique to others approached by the same team with right upper quadrant incision or right semicircular umbilical skin-fold incision. In all 19 cases, adequate pyloromyotomy was performed in a good ranging time without any intra- or post-operative complications, achieving excellent early cosmetic results. The feasibility of single-port, laparoscopic-assisted pyloromyotomy obtained in this small sample suggests that this procedure could be an excellent alternative to open or laparoscopic pyloromyotomy as long as it acts as intermediary between the two techniques.

Urachal remnants are rare congenital anomalies generally treated with open surgery. In the last decade laparoscopic treatment of these anomalies became more frequent. The Authors report their experience about minimally invasive treatment of remnants.Four children with urachal remnants underwent minimally invasive surgery. Two children with infected urachal cysts underwent delayed laparoscopic assisted excision. In the others two patients with urachal cysts diagnosed incidentally the excision of the remnant was performed laparoscopically.In all cases the excision of remnants was accomplished easily. Operative time ranged from 40 to 90 minutes. Intra- or post-operative complications and recurrences did not occur and the cosmetic results were very good.Minimally invasive surgery for urachal remnants is reliable, diagnostic and therapeutic at the same time. In case of complicated urachal cysts the delayed laparoscopic assisted treatment ensure a minimally invasive surgery with a single anesthesia.

Many surgical approaches to posterior urethral diseases are reported in published data. The authors report a case of a patient with prostatic urethral post-traumatic fistulae, probably developed from an abscess that developed after a surgical intervention to correct a pubic symphysis fracture. The fistulae were repaired with an unusual mininvasive endourologic procedure, using the hyaluronic acid dextranomer, which is commonly used in vesicoureteral reflux treatment.

Animal bites to human external genitalia are rare. Only a few cases of scrotal dog bite in children have been reported. We present an additional specific case of a scrotal dog bite in a child because the lesion and its repair have not been previously reported in published pediatric studies. A traumatic resection of the right testicular vas deferens was repaired by microsurgical vasoepididymal anastomosis. A review of the published data was also performed to analyze the management of scrotal dog bite lesions.

We analyzed a new urethra preserving approach, double-cross flap protection, during tubularized incised plate urethroplasty. We compared the results of 57 patients treated with this new procedure and 80 patients treated with 2 different techniques.We studied 137 patients with hypospadias between October 2002 and March 2008. Patients were divided into 3 groups. Group 1 consisted of 40 patients (mean age 50 months) undergoing tubularized incised plate urethroplasty. Group 2 included 40 patients (mean age 48 months) undergoing tubularized incised plate urethroplasty with dorsal subcutaneous flap. Group 3 consisted of 57 patients (mean age 39 months) undergoing tubularized incised plate urethroplasty with 2 de-epithelialized preputial flaps twisted ventrally and sutured individually over the neourethra. All patients were operated on by the same surgeons. Statistical analysis of postoperative complications was performed by ANOVA and chi-square test.In Group 1 fistula developed in 6 patients (15%) and was associated with stenosis of the neourethra in 4 (10%). In Group 2 fistula developed in 4 patients (10%). In Group 3 no fistula was observed, but mild stenosis of the neomeatus developed in 3 patients (5.3%), which was treated with dilation. Thus, the incidence of fistula in group 3 was significantly less (p = 0.015).Double-cross flap protection is safe and significantly reduces the incidence of postoperative fistula.

The authors report the case of a female patient, affected by long-gap oesophageal atresia, who, at 5 months old, was operated on for retrosternal substitution with a right-transverse antiperistaltic colic segment, in her local district hospital. Due to the anomalous position the neooesophagus never worked, and the baby was seriously dysphagic and failed to thrive. For this reason, when she was 11 months old, she was reoperated in our department. Through a medium sternolaparotomy the antiperistaltic colon was removed and replaced between the left and right colon; reconstruction was carried out with a retrosternal and isoperistaltic segment of ileo-caecum. The reoperation resolved her problems. This case is reported to confirm the author's opinion that all intestinal conduits must be positioned in the isoperistaltic direction.

The authors report a case of duplication of the entire small intestine manifested by frequent haemorrhages originating from a peptic ulcer located distally to the duplication. The peptic ulcer was provoked by the ectopic gastric mucosa of the duplication. Surgery consisted "stripping" the mucosa of the duplicated tract according to Wrenn's technique. Other surgical methods for treating this malformation are discussed in detail. The literature describing similar cases is reviewed.

This paper reports on the experience of the Paediatric Surgery Clinic of the University of Bologna in testicular autotransplantation utilising microsurgical techniques. Besides evaluating indications for the intervention, the authors present case histories they have accumulated over twenty months (September 1982-May 1984). Subject to discussion are some notes on surgical technique with particular attention to the dissection of the funiculus and to the construction of microsurgical vascular anastomoses. The short-term and medium-term results of 4 autotransplants are presented and commented upon.
