Primary non-refluxing megaureter: Natural history, follow-up and treatment. Eur J Pediatr 2024; 183:2029-2036. [PMID: 38441661 PMCID: PMC11035438 DOI: 10.1007/s00431-024-05494-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 02/17/2024] [Accepted: 02/23/2024] [Indexed: 04/23/2024]
Abstract
Primary non-refluxing megaureter (PMU) is a congenital dilation of the ureter which is not related to vesicoureteral reflux, duplicated collecting systems, ureterocele, ectopic ureter, or posterior urethral valves and accounts for 5 to 10% of all prenatal hydronephrosis (HN) cases. The etiology is a dysfunction or stenosis of the distal ureter. Most often PMU remains asymptomatic with spontaneous resolution allowing for non-operative management. Nevertheless, in selective cases such as the development of febrile urinary tract infections, worsening of the ureteral dilatation, or reduction in relative renal function, surgery should be considered. CONCLUSION Ureteral replantation with excision of the dysfunctional ureteral segment and often ureteral tapering is the gold-standard procedure for PMU, although endoscopic treatment has been shown to have a fair success rate in many studies. In this review, we discuss the natural history, follow-up, and treatment of PMU. WHAT IS KNOWN • PMU is the result of an atonic or stenotic segment of the distal ureter, resulting in congenital dilation of the ureter, and is frequently diagnosed on routine antenatal ultrasound. WHAT IS NEW • Most often, PMU remains asymptomatic and clinically stable, allowing for non-operative management. • Nevertheless, since symptoms can appear even after years of observation, long-term ultrasound follow-up is recommended, even up to young adulthood, if hydroureteronephrosis persists. • Ureteral replantation is the gold standard in case surgery is needed. In selected cases, however, HPBD could be a reasonable alternative.

Unusual position of pilonidal sinus in children may explain its malformative etiology: Case report and review of the literature. Int J Surg Case Rep 2024; 116:109444. [PMID: 38430899 PMCID: PMC10944116 DOI: 10.1016/j.ijscr.2024.109444] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2024] [Revised: 02/20/2024] [Accepted: 02/21/2024] [Indexed: 03/05/2024] Open
Abstract
INTRODUCTION Pilonidal sinus is a condition that causes inflammation and abscesses in the sacral region and affects adolescents and young adults. The etiology of this condition remains controversial. CASE PRESENTATION A six year old boy was observed to have an orifice in the frontonasal region which contained hair. He had two previous infections which were treated with antibiotics. Magnetic Resonance Imaging showed no cranial malformations. Surgery was performed under general anesthesia and the pilonidal sinus was completely excised. At follow-up the child was in good health. CLINICAL DISCUSSION This case in a child with a frontonasal skin anomaly highlights that skin anomalies may be a cause of pilonidal sinus. CONCLUSION Skin malformations can be the underlying cause of pilonidal sinus in some cases.

Abstract
INTRODUCTION AND IMPORTANCE Apocrine Hidrocystoma is a relatively rare benign tumour that begins from the apocrine sweat glands of the head and neck. The Authors present a case series of children with urogenital localization. CASES PRESENTATION Two boys (15 years and 9 years) presented with a small mass on the glans. Another 15-year-old boy presented with a cystic lesion in the right side of the scrotum where he had a previous surgery. The last case, a 17-year-old boy, presented because of a penile cyst of 8 mm. All four had surgical operations because of aesthetic discomfort or problems during micturition. Histological examination showed a diagnosis of apocrine hidrocystoma in all cases. CLINICAL DISCUSSION This benign tumour rarely affects the urogenital system in children, but when it happens the child can have discomfort and proper treatment is mandatory. CONCLUSION Surgery is the preferred treatment with a low risk of recurrence.

In Which Patients and Why Is Laparoscopy Helpful for the Impalpable Testis? Minim Invasive Surg 2022; 2022:1564830. [PMID: 36249585 PMCID: PMC9553680 DOI: 10.1155/2022/1564830] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Accepted: 09/08/2022] [Indexed: 11/18/2022] Open
Abstract
Since laparoscopy has been proposed in the management of the nonpalpable testis (NPT), this technique has been widely diffused among pediatric surgeons and urologists, but its application is still debated. We conducted a retrospective review to highlight how diagnostic and surgical indications for laparoscopy are selective and should be targeted to individual patients. From 2015 to 2019, 135 patients with NPT were admitted to our surgical division. Of these, 35 were palpable on clinical examination under anesthesia and 95 underwent laparoscopy. The main laparoscopic findings considered were: intra-abdominal testis (IAT), cord structures that are blind-ending, completely absent, or entering the abdominal ring. The patients' mean age was 22 months. In 48 cases, an IAT was found, and 42 of these underwent primary orchidopexy while 6 had the Fowler-Stephens (FS) laparoscopic procedure. Of the first group one patient experienced a testicular atrophy while two a reascent of the testis. In the FS orchidopexy group, one patient had testicular atrophy. Cord structures entering the internal inguinal ring were observed in 35 children, and all were surgically open explored. In 3 cases of these, a hypotrophic testis was revealed and an open orchidopexy was executed. In the remaining the histological examination revealed viable testicular cells in four patients and fibrosis, calcifications, and hemosiderin deposits in the others. Eleven patients presented with intrabdominal blind-ending vessels and one a testicular agenesia. A careful clinical examination is important to select patients to submit to laparoscopy. Diagnostic laparoscopy, and therefore, the anatomical observation of the testis and cord structures are strictly related to develop a treatment plan. In IAT, many surgical strategies can be applied with good results. Laparoscopy offers a concrete benefit to the patient.

Esophageal impedance baseline in infants with bronchopulmonary dysplasia: A pilot study. Pediatr Pulmonol 2022; 57:448-454. [PMID: 34783199 DOI: 10.1002/ppul.25758] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 11/07/2021] [Accepted: 11/14/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND Bronchopulmonary dysplasia (BPD) may induce gastroesophageal reflux (GER). Esophageal impedance baseline values (BI) reflect mucosal inflammation. Our aim was to evaluate BI levels in preterm infants with BPD compared with those without BPD and to identify BI predictors. METHODS This is a retrospective pilot study including infants born <32 weeks' gestational age (GA) who underwent esophageal multichannel intraluminal impedance (MII)-pH. Univariate/multivariate analysis were performed to compare data between BPD and non-BPD infants and to identify BI predictors. A subgroup analysis was performed in infants born <29 weeks' GA, at highest risk for BPD. RESULTS Ninety-seven patients (median GA 285/7 weeks, mean postnatal age 49 days, 29 with BPD), were studied. BPD infants had significantly lower birth weight compared with non-BPD infants (750 vs. 1275 g), were more immature (274/7 vs. 290/7 weeks GA), were older at MII-pH (79 vs. 38 days) and received less fluids during MII-pH (147 vs. 161 ml/kg/day). The same findings were found in the group of 53 infants born <29 weeks. BPD versus non-BPD infants had significantly lower BI (2050 vs. 2574 ohm, p = 0.007) (<1000 ohm in five BPD infants vs. one non-BPD) whereas the other MII-pH parameters were not significantly different. Multiple regression analysis found that increasing chronological age was positively associated with BI (B = 9.3, p = 0.013) whereas BPD was associated with lower BI (B = -793.4, p < 0.001). CONCLUSIONS BPD versus non-BPD infants had significantly lower BI despite similar MII-pH data. BPD and chronological age predicted BI, whereas only BPD predicted BI in the most immature infants.

Abstract
Bronchogenic Cysts (BCs) are benign congenital malformations commonly located in the mediastinum. In recent years the development of antenatal diagnosis has changed the BCs management allowing an earlier minimally invasive approach. We report a case of an asymptomatic 8-months-old girl with antenatal diagnosis of subcarinal posterior mediastinal BC. Thoracoscopic excision of the cyst was successfully performed. The management of antenatally diagnosed BCs is discussed. Thoracoscopic treatment of BCs is safe and effective with the advantage of a reduced morbidity compared to thoracotomy.

Abstract
Fowler-Stephens Laparoscopic Orchiopexy (FSLO) permits the mobilization of Intra-Abdominal Testis (IAT) to the scrotal position after spermatic vessel ligation. We reported our experience of FSLO for IAT. The charts of all boys who underwent a FSLO were retrospectively reviewed. Data were analysed for demographic data, procedure, complications and follow-up results. From January 2008 to June 2016, 160 laparoscopies for Non Palpable Testis (NPT) were performed at a mean age of 3,2 years. 61% of patients had a right NPT, while 6% were bilateral. In 64 cases, an IAT was found: 20 were managed by FSLO with a two-stage procedure in 11 patients. There were no differences in hospitalisations; one patient had a prolonged ileus. Follow-up ranged from 1 to 8 years. Of the 20 patients who underwent FSLO, testicular atrophy developed in three; the remaining testes were in the scrotal position, with normal consistency. FSLO was applied in 31% of IAT. The overall success rate of the technique was 85 %. The percentage of atrophy associated after spermatic vessels interruption appears to provide a good chance of testicular survival.

Abstract
Background and Objectives: Laparoscopy is the preferred method when operating in the abdomen. In this study, we evaluated systemic and morphological peritoneal cytokine modifications (RANTES/CCL5 and MCP-1/CCL2) due to CO2 pneumoperitoneum in rats. Methods: Twenty-five prepubertal Sprague-Dawley rats were randomized into three groups. Pneumoperitoneum lasting 30 minutes, was induced with a flow of 0.5 L/min, in two groups (S1 and S2, n = 20), at a P/CO2 of 6 and 10 mm Hg, respectively. In the control group (C, n = 5), only anesthesia was carried out. All animals were sacrificed after 24 hours. The serum of the rats was collected for ELISA, and the levels of the cytokines RANTES and MCP-1 were investigated. An immunohistochemical analysis of RANTES and MCP-1 was performed on samples of the peritoneum, and the morphological evaluation was conducted with a blinded evaluation by two independent, experienced pathologists by using a grading system (0, 1+, 2+, 3+: no, faint, moderate, and strong reactivity, respectively). Results: RANTES mean levels were significantly different in the S1, S2, and C groups (70.3 ± 2.26, 58.23 ± 4.32, 29.66 ± 4.03, respectively, P = .0001). The levels of MCP-1 were 32.1 ± 1.63 in the S1 group, 27.0 ± 9.26 in the S2 group, and 16.4 ± 9.55 in the C group (P = .159). Normal control peritoneum showed little reactivity, whereas a moderate to strong cytoplasmic reaction to anti-CCL5/CCL2 antibodies was observed in mesothelial and inflammatory cells in the S1 and S2 groups. Conclusion: CO2 pneumoperitoneum evokes an inflammatory response by modifying plasma RANTES levels and peritoneal CCL5/CCL2 expression.

Abstract
PURPOSE The purpose of this study was to quantify the experience of five Italian centers on the diagnosis and management of isolated fallopian tube torsion (IFTT) in children. METHODS We retrospectively reviewed the data of 20 patients aged 1-16 years of age with surgically diagnosed IFTT between 1991 and 2017 from five Italian centers of pediatric surgery. We analyzed common presenting signs, symptoms, and radiographic findings, as well as surgical interventions to describe management offering further insight into the diagnosis and treatment of this rare entity. RESULTS Twenty cases of IFTT were collected. Median age was 13.1 years. Menarche was present in 14 cases. A clinical history of abdominal pain was present in 13 patients, whereas in 7 patients the clinical picture was an acute abdomen. Ultrasonography was the first diagnostic examination in 16 cases. Surgical approach was by laparoscopy in 16 cases and laparotomy in 4 cases. In 11 patients IFTT was associated with another pathologic condition. In 7 of the remaining 9 IFTT without pathologic association, the girls played sports. Salpingectomy was performed in 13 patients and de-torsion in 7. CONCLUSIONS IFTT is a rare condition that seems to occur in younger adolescents. Vague clinical presentation contributes to low preoperative suspicion. IFTT should be considered in girls with abdominal pain who practice sports with sudden body movements. Preoperative suspicion may be increased based on radiographic findings of an enlarged tubular/cystic structure with adjacent normal ovary. Conservative management is controversial but could be preferred in order to provide the best option for future fertility of these girls. TYPE OF STUDY Treatment Study (Retrospective Study) - Level IV.

Abstract
OBJECTIVES Constipation is a common problem in children, and most of the time, the cause is defined as functional. Our hypothesis is that children with functional refractory constipation had anatomic alterations of the colon. METHODS All children with chronic refractory constipation who visited our centre underwent accurate clinical examination, contrast enema (CE), anorectal manometry (ARM) and rectal suction biopsies (RSB). In case of functional constipation, three operators measured the size of the colon using radiograms and calculated the ratio based on the width of the second lumbar vertebra. The measurements carried out were compared with those reported in the literature on patients of the same age without constipation. RESULTS Over a period of 24 months, 69 patients with chronic refractory constipation, aged between 1 and 14 years, visited our department. A CE was performed on 67, and 2 were excluded because of anal stenosis. Sixty-five underwent anorectal manometry. Rectal suction biopsies were needed in 14 children, and 2 of them were found to have colonic aganglionosis. After a complete evaluation, 57 (82.61%) patients were diagnosed having functional constipation. By comparing the data of the patients with those of normal children reported by the other authors, we found that none of the measurements was statistically significant except for the rectosigmoid length: the mean value in one-year-old patients was 19.03 vs. 9.75, and in older children, it was 19.46 vs. 9.59. CONCLUSIONS Recognizing an anatomic anomaly in patients suffering from functional constipation is important for specific treatment, especially when the ratio (rectosigmoid length/L2) is higher than 15.

Abstract
BACKGROUND The association between cardiorespiratory events (CRE) and gastro-esophageal reflux (GER) among neonates is still controversial. AIMS To test such an association in preterm and term infants. STUDY DESIGN Prospective observational study. SUBJECTS Forty-seven infants with suspected GER and recurrent CRE admitted at a neonatal intensive care unit, who underwent simultaneous and synchronized 24-hour recording of heart rate (HR), peripheral oxygen saturation (SpO2) and pH-impedance monitoring (MII-pH). HR/SpO2 data were filtered to avoid artefactual episodes of hypoxia and hypoperfusion. OUTCOME MEASURES The main outcome measure was the symptom association probability (SAP), with a 2-minute time window. Infants with positive (>95%) and negative (≤95%) SAP index tests were compared by univariate and multivariate statistics. RESULTS Median gestational age at birth was 294/7 weeks, median age at study 36 days. We recorded 3341 GER events and 4936 CRE (4710 desaturations, 226 bradycardias); 609/4936 (12%) CRE were temporally associated with GER episodes: 338 preceded and 271 followed GER events. The SAP index was significant in 5/47 (11%) patients. The SAP index including only CRE following GER events was significant in 3/47 (6%). There was no significant difference in the number of acid, weakly acid, non-acid, pH-only events preceding or following CRE between infants with SAP-positive and SAP-negative tests. Infants with positive SAP-index tests compared to those with SAP-negative tests had lower weight gain in the three days preceding the test and tended to have lower birth weight. CONCLUSIONS GER and CRE were associated in <11% of patients. The evaluation of ponderal growth might be helpful in predicting such an association.

Abstract
The percutaneous endoscopic gastrostomy is the best technique to use in case of children requiring long-time enteral nutrition. The first replacement of the tube is easy in most of the patient, but this step can be extremely problematic in patients with compromised general conditions. The authors report their experience in some cases. Two boys with endoscopic gastrostomy had a deterioration in the general conditions, when replacing the probe, these conditions contraindicated anaesthesia for which the "cut-and-push" technique was adopted in a patient with heart malformation and a local anaesthetic in a neuropathic patient. Both the boys died a few days after this procedure. In our opinion, in children who are not using anaesthesia to reposition the gastrostomy probe, it is best to continue feeding through the nasogastric probe.

Abstract
Isolated tubal torsion (ITT) is a rare cause of acute abdominal pain. Preoperative diagnosis is difficult because of a lack of specific signs. Surgery is recommended to preserve the integrity of the tube. Seven patients of median age of 13 years (range 9 to 15) came to our observation for worsening abdominal pain, nausea and vomiting. On admission, all girls had blood tests and ultrasound. Laparoscopy was performed for diagnosis in all cases. The girls had one-month and one-year ultrasound and clinic follow up. In all cases diagnosis was delayed, median 66 hours after the onset of symptoms and laparoscopy showed necrosis of the Fallopian tube. In five girls a laparoscopic salpingectomy was performed. In the other two, an open salpingectomy was necessary because of pelvic adhesions. Histology showed a hemorrhagic infarction of the Fallopian tubes. At follow up all patients were asymptomatic with normal ovaries, but one ovarian cyst. In the differential diagnosis of acute abdominal pain in children or female adolescents the possibility of ITT should be considered for a conservative treatment. Laparoscopy allows for definitive diagnosis and treatment.

Abstract
We retrospectively reviewed the results of transscrotal orchidopexy in the surgical management of palpable testis. From January 2014 to June 2017, 130 male children with a total of 140 palpable undescended testes (UDT) underwent transscrotal orchidopexy. The charts were retrospectively reviewed for demographic data, preoperative position and mobility of the testis, patency of the peritoneal vaginal duct (PVD), and post-operative complications. The resting position of the testis and its traction towards the scrotum were assessed before surgery and under anaesthesia. The mean age of the patients was 4.6 years. The position of the testis assessed at surgery was in most cases at the external inguinal ring (62.8%), at the neck of the scrotum (15.7%), in the inguinal canal (12.8%), or in an ectopic position (8,5%). A PVD was found in 66 testes (47.1%). Two surgical cases required an inguinal incision. In each patient, the postoperative course was unremarkable. The testicle at 1-year follow-up was in a scrotal position in 134 cases, but 6 patients required a second surgical intervention for re-ascent of the testis. No testicular atrophy or inguinal hernias were observed. Transscrotal orchidopexy is a simple and effective procedure for the treatment of palpable UDT. The incidence of complications is low and manageable, with rapid postoperative recovery and early resumption of normal activities.

Abstract
Background Pediatric cholelithiasis unrelated to hematological disorders is an increasing disease. We analyzed our experience in the surgical treatment of these cases to evaluate risk factors, clinical presentation, intervention and follow-up. Methods From January 2010 to December 2016, we retrospectively recorded all data (hematological study, familiarity, use of lithogenic drugs and parenteral nutrition) of cholecystectomies for cholelithiasis not related to hematological diseases. The body mass index (BMI) was calculated (obesity if > 25), medical treatment, surgery and follow-up were evaluated. All patients underwent ultrasound for diagnosis and major biliary tract assessment prior to surgery. All patients had a 1-year follow-up. Results There were twenty-four cases (eight males), with a median age of 11.2 years. Predisposing factors were familiarity in 19, use of lithogenic drugs in 5 and total parental nutrition (TPN) in 3. Median BMI was 19.8 kg/m2, with BMI > 25 kg/m2 in eight cases. Regarding the clinical presentation, 14 had acute pain in the right upper quadrant, 5 had cholecystitis and 5 had non-specific abdominal pain. The medical treatment lasted 6 months in all, except for five (three operated after 2 months and two after 12 months). Preoperative ultrasound did not show stones in the biliary tract. MRI was performed in three cases for suspected malformation of the biliary tract (negative). Laparoscopic cholecystectomy was performed in all cases: mean intervention time was 95 min. A case of postcolecystectomy syndrome was found. At follow-up, all were asymptomatic, except two (recurrent abdominal pain). Conclusion Main predisposing factors are familiarity and obesity. Preoperative ultrasound in our series replaced the intraoperative study of the biliary tract. Laparoscopic cholecystectomy is the gold standard.

Abstract
BACKGROUND Inguinal and/or inguino-scrotal swellings, such as hernia and hydrocele, are among the commonest anomalies in childhood. Hydrocele of the canal of Nuck is an uncommon diagnosis and a rare cause of swelling in women that occurs due to a patent vaginal process. METHODS From January 2001 to January 2016, 353 female patients 1-14 years of age were admitted to our university hospital division for inguinal swelling. We have performed 403 inguinal approaches, and of these, 399 (99%) had inguinal hernias, 3 (0.74%) had a cyst of the canal of Nuck, and 1 (0.24%) had a lipoma. All of the patients with Nuck cysts underwent surgical exploration of the swelling through a right inguinal skin crease incision. RESULTS The patients were between the ages of 1 and 8 years. The cyst sizes varied between 25 and 40 mm. All the patients exhibited right, tender, painless, non-reducible masses. In all patients, ultrasound confirmed the suspected diagnosis. The histological findings revealed fibrous-walled cystic formations with mild chronic inflammatory infiltrate that were covered by mesothelial epithelium. The patients' postoperative follow-ups at 1, 6 and 12 months revealed normally healed incisions with no recurrences. CONCLUSIONS The surgical findings and the histological demonstrations of serous epithelium seemed to validate the hypothesis that the patency of the inguinal canal combined with fluid secretion of the peritoneal serosa participated in the formation of the cysts. Surgery with high ligature of the vaginal process is considered the therapy of choice for this pathology.

Abstract
BACKGROUND Inguinal and/or inguino-scrotal swellings, such as hernia and hydrocele, are among the commonest anomalies in childhood. Hydrocele of the canal of Nuck is an uncommon diagnosis and a rare cause of swelling in women that occurs due to a patent vaginal process. METHODS From January 2001 to January 2016, 353 female patients 1-14 years of age were admitted to our university hospital division for inguinal swelling. We have performed 403 inguinal approaches, and of these, 399 (99%) had inguinal hernias, 3 (0.74%) had a cyst of the canal of Nuck, and 1 (0.24%) had a lipoma. All of the patients with Nuck cysts underwent surgical exploration of the swelling through a right inguinal skin crease incision. RESULTS The patients were between the ages of 1 and 8 years.

Abstract
OBJECTIVE The authors present their experience in the management of pediatric patients with Herlyn-Werner-Wunderlich syndrome (HWWS) considering clinical classification and anatomical characteristics of the malformation. METHODS All the data of the patient presented at our Pediatric Surgery Unit from February 2010 to August 2015 were collected. According to the type of malformations, patients were divided in 3 groups: A (completely obstructed hemivagina), B (incompletely obstructed hemivagina), and C (communication between the duplicated cervices). RESULTS Six patients were treated in the study period. The mean age was 9 years (2 months-15 years). According to the characteristics of the HWWS, we had 5 patients in group A, 1 in group B, and none in group C. One-stage surgical treatment was performed in all cases of complete obstruction, but in one case a second look was necessary for a better resection of the septum. At a mean follow-up of 18 months all patients were symptoms free. CONCLUSIONS Prognosis of this malformation is good in case of early diagnosis and treatment. We suggest that when a renal agenesia is diagnosed, the patient needs an ultrasonographic follow-up of the contralateral kidney but also of the genital tract to find each minimal abnormalities, furthermore, a MRI scanning before the onset of menstruation can be necessary.

Abstract
Survival of preterm infants have dramatically improved over the last decades. Nonetheless, infants born preterm remain vulnerable to many complications, including necrotizing enterocolitis (NEC). The severity of the disease and the mortality rate are directly correlated with decreasing gestational age and birth weight. Despite surgical treatment mortality rate remains very high in extremely premature infants, especially in newborns at the lowest limit of viability. Survival of infants of birth weight (BW) below 750 g has been increasingly reported in recent years, however the overall mortality in extremely low "BW" infants (ELBW) requiring surgery for NEC has not decreased over the past years. We describe our experience with a male preterm infant who survived after an ileostomy procedure for Bell stage II NEC, with improving neuromotor skills at 2 years follow up. Although standard indication to surgery is Bell stage III, in our case the choice of minimal laparotomy, exploration of the bowel and ileostomy at Bell stage II was safe and effective. Our experience suggest that surgery has not a negative impact on survival and ileostomy could prevent further damage of the bowel in NEC. We hypothesize that indication to surgery at an earlier stage may prevent further progression of the disease without a significantly negative impact on survival. Further studies are needed to confirm the appropriateness of this approach in ELBW infants.

Abstract
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.

Abstract
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).

Abstract
Vesicoureteral reflux (VUR) is the retrograde passage of urine from the bladder to the upper urinary tract. It is the most common congenital urological anomaly affecting 1-2% of children and 30-40% of patients with urinary tract infections. VUR is a major risk factor for pyelonephritic scarring and chronic renal failure in children. It is the result of a shortened intravesical ureter with an enlarged or malpositioned ureteric orifice. An ectopic embryonal ureteric budding development is implicated in the pathogenesis of VUR, which is a complex genetic developmental disorder. Many genes are involved in the ureteric budding formation and subsequently in the urinary tract and kidney development. Previous studies demonstrate an heterogeneous genetic pattern of VUR. In fact no single major locus or gene for primary VUR has been identified. It is likely that different forms of VUR with different genetic determinantes are present. Moreover genetic studies of syndromes with associated VUR have revealed several possible candidate genes involved in the pathogenesis of VUR and related urinary tract malformations. Mutations in genes essential for urinary tract morphogenesis are linked to numerous congenital syndromes, and in most of those VUR is a feature. The Authors provide an overview of the developmental processes leading to the VUR. The different genes and signaling pathways controlling the embryonal urinary tract development are analyzed. A better understanding of VUR genetic bases could improve the management of this condition in children.

Abstract
Isolated fallopian tube torsion (IFTT) is a rare occurrence characterized by the rotation of the fallopian tube on its own axis, without twisting the ipsilateral ovary. Pre-operative diagnosis is difficult due to the lack of specific clinical symptoms and radiological signs. The etiology is to date unknown and only some pre-disposing factors have been reported. The history, clinical presentation, laboratory findings and surgical treatment of five patients aged 12-16 with IFTT were evaluated. All patients came to be examined for worsening abdominal pain, nausea or vomiting. 75% of them practiced sports involving sudden changes in body position. They all underwent blood tests, ultrasound and Magnetic Resonance and then laparoscopy for the persistence of acute symptoms. Laparoscopic salpingectomy was performed in three patients. Another two needed a conversion to open salpingectomy due to the presence of pelvic adhesions. During the follow-up period, every girl was fine. The cause of IFTT is undetermined. In this series, a close association between IFTT and sports causing rapid body movements was found. The possibility of IFTT should be considered in the differential diagnosis of acute abdominal pain in children or adolescent females, especially if they practice sports.

Abstract
INTRODUCTION Carbon dioxide (CO2) used in laparoscopy evokes local and systemic effects. This study was designed to evaluate the histopathologic morphologic changes due to CO2 and air insufflation, at different pressure levels, on visceral and parietal peritoneum in rats. MATERIALS AND METHODS A total of 56 rats were object of the study, randomly divided into five groups. Pneumoperitoneum (PN) was maintained for 30 minutes, at a flow rate of 0.5 L/min and at a pressure of 10 and 6 mm Hg with CO2 (group S1-S2, n = 32) and filtered air (group A1-A2, n = 16). Only anesthesia was performed in the fifth group (group C, n = 8). Peritoneal samples were obtained 24 hours later for blinded histological evaluation. A grading system was adopted to evaluate histological peritoneal changes (0, no change; 1, mild; 2, moderate; and 3, severe) such as mesothelial aspect, inflammatory response, edema, and hemorrhage. The score reflected the severity of damage and was calculated by the sum of the degree evaluated separately. Values were compared with the analysis of variance analysis. RESULTS CO2 and air insufflation caused reactive mesothelial cells and peritoneal inflammation of different degrees depending on the level of intra-abdominal pressure (IAP) and type of gas. These modifications were absent in group C and were less evident in low pressure S2 group with respect to S1 and A1-A2 groups. The average values of histopathologic peritoneal score showed significant differences between S2 (11.5) versus S1 groups (16.83) with respect to A groups (A1 = 27.83; A2 = 20.5) and compared with the controls (C = 2.5). CONCLUSIONS Our data confirm that PN affects the peritoneal integrity. The grades of morphological peritoneal changes are related to the level of IAP. Low CO2 pressure causes minor peritoneal changes with respect to high pressure and air insufflation.

Abstract
AIM Aim of the study was to compare multichannel intraluminal impedance (MII)-pH monitoring versus pH only, as first-line assessment of gastroesophageal reflux (GER) in children and to define the relation between GER and symptoms as well relation between types of GER and age of children. METHODS All the patients with GER were divided in three groups: A, younger than 24 months, B, older than 24 months with typical symptoms and C, older than 24 months with atypical symptoms. The groups A and C underwent a combined MII-pH recording. The group B underwent a only pH recording. MII-pH measurements were performed in 89 children (63 group A and 26 group C), only pH measurements in 170 cases (group B). RESULTS Sixty-seven of the 247 pH measurements demonstrated abnormal reflux indices: 25.0% (group A), 28.8% (group B) and 20.8% (group C). The number of the reflux periods and the total reflux index were highest in the patients of the group B, but the number of long reflux periods was highest in the group C. Abnormal values at MII results were found in 36 cases: 41.7% in group A (high number of weakly acid refluxes events) and 45.8% in group C (similar number of acid and weakly acid events). The MII were considered pathological because of high number of reflux episodes and symptom index ≥ 50% respectively in 60.0% and 40.0% of the group A and 27.3% and 62.7% of the group C. CONCLUSION MII-pH study must be reserved to patients younger than 2-year old (high probability of weakly acid reflux) and children with atypical symptoms.

Abstract
AIM: To retrospective review the laparoscopic management of Meckel Diverticulum (MD) in two Italian Pediatric Surgery Centers.
METHODS: Between January 2002 and December 2012, 19 trans-umbilical laparoscopic-assisted (TULA) procedures were performed for suspected MD. The children were hospitalized for gastrointestinal bleeding and/or recurrent abdominal pain. Median age at diagnosis was 5.4 years (range 6 mo-15 years). The study included 15 boys and 4 girls. All patients underwent clinical examination, routine laboratory tests, abdominal ultrasound and technetium-99m pertechnetate scan, and patients with bleeding underwent gastrointestinal endoscopy. The abdominal exploration was performed with a 10 mm operative laparoscope. Pneumoperitoneum was established based on the body weight. Systematic overview of the peritoneal cavity allowed the ileum to be grasped with an atraumatic instrument. The complete exploration and surgical treatment of MD were performed extracorporeally, after intestinal exteriorization through the umbilicus. All patients’ demographics, main clinical features, diagnostic investigations, operative time, histopathology reports, conversion rate, hospital stay and complications were registered and analyzed.
RESULTS: MD was identified in 17 patients, while 1 had an ileal duplication and 1 a jejunal hemangioma. Fifteen patients had painless intestinal bleeding, while 4 had recurrent abdominal pain and exhibited cyst like structures in an ultrasound study. Eleven patients had a positive technetium-99m pertechnetate scan. In the patients with bleeding, gastrointestinal endoscopy did not name the source of hemorrhage. All patients were subjected to a TULA surgical procedure. An intestinal resection/anastomosis was performed in 14 patients, while 4 had a wedge resection of the diverticulum and 1 underwent stapling diverticulectomy. All surgical procedures were performed without conversion to open laparotomy. Mean operative time was 75 min (range 40-115 min). No major surgical complications were recorded. The median hospital stay was 5-7 d (range 4-13 d). All patients are asymptomatic at a median follow up of 4, 5 years (range 10 mo-10 years).
CONCLUSION: Trans-umbilical laparoscopic-assisted Meckel’s diverticulectomy is safe and effective in the treatment of MD, with excellent results.

Abstract
Cryptorchidism represents the most common endocrine disease in boys, with infertility more frequently observed in bilateral forms. It is also known that undescended testes, if untreated, lead to an increased risk of testicular tumors, usually seminomas, arising from mutant germ cells. In normal testes, germ cell development is an active process starting in the first months of life when the neonatal gonocytes transform into adult dark (AD) spermatogonia. These cells are now thought to be the stem cells useful to support spermatogenesis. Several researches suggest that AD spermatogonia form between 3 and 9 months of age. Not all the neonatal gonocytes transform into AD spermatogonia; indeed, the residual gonocytes undergo involution by apoptosis. In the undescended testes, these transformations are inhibited leading to a deficient pool of stem cells for post pubertal spermatogenesis. Early surgical intervention in infancy may allow the normal development of stem cells for spermatogenesis. Moreover, it is very interesting to note that intra-tubular carcinoma in situ in the second and third decades have enzymatic markers similar to neonatal gonocytes suggesting that these cells fail transformation into AD spermatogonia and likely generate testicular cancer (TC) in cryptorchid men. Orchidopexy between 6 and 12 months of age is recommended to maximize the future fertility potential and decrease the TC risk in adulthood.

Abstract
AIM Constipation is a common pediatric problem. Sometimes the hospitalization is necessary and in these patients the organic cause should be verified. The authors report their experience in the management of children with severe constipation. METHODS Anorectal manometry (ARM) was performed after a careful examination of perineum and bowel disimpaction. Once organic cause had be excluded, the patient got medical therapy. If recto-anal inhibitory reflex (RAIR) was absent, not collaborative patient or medical treatment failed, the child underwent contrast enema (CE) and rectal suction biopsies (RSB). Local anesthetics were used for anal fissures or internal anal sphincter (IAS) hypertonia. Anal malformations and Hirschsprung's disease (HD) were surgically treated. Posterior sagittal anorectoplasty was performed for anal malformations. RESULTS In 5 years 98 children (63 males) were observed (mean age 6 years). 5 children were premature for gestational age, 4 presented failure to thrive, 5 anal malformations and 45 anal fissures. ARM was performed in 87 children and 74 of them showed normal RAIR. Hypertonia of the IAS was recorded in 38 patients. RAIR was absent/unclear in 13 patients. Follow-up revealed 6 patients (negative to ARM) with poor results without oral laxative. CE was performed in 19 children (2 positive cases) and RBS in 25 patients (2 cases of HD). CONCLUSION Children with severe constipation must be carefully observed and studied because of not negligible incidence of organic cause. The first step in the management of these patients is the evacuation of the fecaloma.

Abstract
AIM Recently laparoscopic endorectal pull-through (LERPT) has been widely performed for treatment of Hirschsprung's disease (HD) as a one stage procedure. In long segment aganglionosis (LSA) and in case of total colonic aganglionosis (TCA) a staged procedure can be preferred. The authors report their experience in the staged LERPT for LSA and TCA. METHODS In the last five years we treated 4 infants (3 male, 1 female) with LSA and TCA. The mean age at presentation was 40 days (2-110 days). In 3 patients we performed in the first step rectal biopsies, multiple laparoscopic biopsies and stoma. In one case ‑ presenting as small bowel obstruction - we performed an emergency laparotomy for ileostomy and biopsies of the bowel. Histology showed 2 left colon aganglionosis (LCA) and 2 TCA. The LERPT was performed at a main age of 10 months. After stoma closure the LERPT was performed according to Georgeson's technique. RESULTS There were no intraoperative complications. The patient with previous laparotomy needed conversion because of the abdominal adhesions. The two infants with LCA had preoperative and recurrent postoperative enterocolitis. In one case a successful posterior anorectal myectomy was performed. At follow up the children present constipation. The patient with TCA undergoing to LERPT presents a good frequency of defecation. CONCLUSION Our experience, although on limited series, shows that staged minimally invasive surgical treatment can be safely performed in the LSA and TCA, but conversion can be necessary especially in case of previous laparotomy.

Abstract
Posterior urethral hemangioma (PUH) is a rare congenital lesion, included in group of polypoid or papillary lesion of the prostatic urethra. This lesion is responsible for a variety of symptoms in children that may be associated or isolated, sometimes its finding is occasional. The diagnosis is usually made by ultrasonography and cystourethrogram, but the gold standard is represented by the urethrocystoscopy with double possibility: diagnostic and therapeutic. The Authors report a case of 1-year-old boy with persisting haematuria, in whom a previews cystoscopy didn't find any cause of haematuria. An accurate urethrocystoscopy let to make diagnosis of prostatic urethral polyp, a transurethral resection was performed and pathological assessment confirmed the diagnosis of PUH.

Abstract
BACKGROUND/PURPOSE One-trocar surgery (OTS) includes all video-surgical techniques performed using a single 10-mm port and an operative scope. These techniques can be completely endoscopic or endoscopic assisted. Since 1997, OTS has become the approach of choice in our institution for a variety of laparoscopic, retroperitoneoscopic, and thoracoscopic operations. We report our experience with this technique. METHODS Four hundred fifty-eight patients (age range, 3 months to 17 years) underwent OTS from October 1997 to December 2008. The procedures were transumbilical laparoscopic-assisted (TULA) appendectomy (182 patients), TULA small bowel resection (14 patients), TULA intestinal biopsies (7 patients), laparoscopic adhesiolysis (6 patients), laparoscopic-assisted liver biopsies (5 patients), laparoscopic revision of peritoneal dialysis catheter (3 patients), retroperitoneoscopic varicocelectomy (202 patients), retroperitoneoscopic-assisted renal biopsies (4 patients), retroperitoneoscopic drainage of posttraumatic urinoma (1 patient), retroperitoneoscopic-assisted pyeloplasty (15 patients), and thoracoscopic pleural debridement and decortication for empyema (19 patients). RESULTS The procedure was completed using only one trocar in 399 cases (87.1%). All conversions to multitrocar or open surgery were elective and regarded the retroperitoneoscopic approach during the learning curve (28 of 222, 12.6%; 21 varicocelectomies and 7 pyeloplasties) and the TULA appendectomy because of the appendix mobilization failure (31 of 182, 17%). There were no intraoperative or postoperative complications related to OTS. Wound infection was observed after two TULA appendectomies (1.3%). CONCLUSIONS According to our experience, OTS is a feasible and versatile technique in pediatric surgery, providing a safe, effective, and the least invasive treatment for several different diseases.

Abstract
OBJECT To retrospectively review the value of laparoscopy in the management of impalpable testis. MATERIALS AND METHODS In 1993-2006, 182 laparoscopies for impalpable testis were performed for a total of 194 testicular units. Five laparoscopic findings were considered: testicular ectopia, intra-abdominal testis, and cord structures that are blind ending, completely absent (agenesis) or entering the internal inguinal ring. RESULTS In 62 cases an intra-abdominal testis was found; 18 were classified as high and managed by a laparoscopic Fowler-Stephens procedure. Cord structures entering the inguinal ring were observed in 77 patients and 45 underwent an inguinal exploration: a testis was found in 12 cases and in 33 a remnant was excised. In 35 cases, intra-abdominal blind ending vas and vessels were observed and eight showed testicular agenesis. No major surgical complications were recorded. Follow up ranged from 1 to 3 years. CONCLUSIONS Our study confirms the value of laparoscopy in the management of non-palpable testis, providing a definitive diagnosis by the direct view of spermatic bundle and testis. Ninety-three patients were managed by laparoscopy only, and in 44 it was essential for the subsequent surgical approach. When the internal inguinal ring is patent and/or normal spermatic vessels are present an inguinal exploration is mandatory.

Abstract
AIM The aim of this study was to evaluate the effectiveness of a differential diagnostic approach to Hirshchsprung's Disease (HD) on the basis of age. METHOD Data on 185 consecutive children with suspected HD were subjected to an age-related diagnostic approach. The patients were divided into two groups according to age (A < 1 year; B > 1 year). Children in Group A had rectal suction biopsy (RSB) and contrast enema (CE), and in Group B anorectal manometry (ARM) was performed. Patients with a normal recto-anal inhibitory reflex (RAIR) underwent bowel disimpaction and medical treatment. Only selected cases in Group B underwent RSB and CE. RESULTS In Group A (18 patients) CE showed a colonic transitional zone in three patients, whereas RSB led to the diagnosis of HD in nine. In Group B (167 patients) ARM was not possible in seven patients and it was normal in 140 (normal anal sphincter pressure: 83; hypertonia of the internal anal sphincter: 57). The RAIR was negative in 20 patients. RSB performed in 31 children in Group B confirmed HD in three patients. CONCLUSIONS For patients with a neonatal onset of constipation RSB is the best diagnostic technique. Chronic constipation is rarely due to HD and ARM is a useful non-invasive screening tool.

Abstract
OBJECTIVE Constipation is one of the most frequent disorders of the digestive tract in children and it can be an important problem in paediatric and surgical practice. Most of the time, the cause is psychological or because of a slowing of colonic transit, but it can be a sign of organic gastrointestinal outlet obstruction. Some patients with chronic constipation are resistant to a medical approach and they present with a severe form of constipation that needs recurrent hospital admission. Anorectal manometry (ARM) is a noninvasive procedure and it helps to explain the mechanisms of defecation disorders. The aim of the present study was to evaluate the role of ARM in children with severe constipation. METHOD From October 2003 to October 2006, in the Paediatric Surgery Unit, 85 children - aged more than 1 year - with severe constipation were seen. The mean age was 5 years (range, 1-13). At presentation, every child had abdominal and rectal examination in order to identify abdominal distension or faecal masses. Bowel preparation with enemas was performed before ARM in patient with a rectal faecaloma. Myoelectric activity of the internal anal sphincter and resting anal tone was recorded; recto-anal inhibitory reflex (RAIR) was tested to exclude Hirschsprung's disease (HD). Anal tone was considered normal until 50 cm H(2)O. When the RAIR was absent, the patient underwent rectal suction biopsies (RSB) for histology and acetylcholinesterase histochemistry. In cases of normal or high anal tone with the RAIR present, the child had bowel cleaning, medical treatment, 2- and 6-month follow-up. Children with ineffective treatment at follow-up underwent RSB. In case of HD, a laparoscopic-assisted endorectal pull-through (ERPT) according to Georgeson's technique was performed. RESULTS Seventy per cent of the patients had bowel preparation before ARM. In four patients the ARM was impossible to assess because of crying. In 28 patients, the anal tone result was higher than 50 cm H(2)O and local treatment with anaesthetic agents was used for 8 weeks. Seventeen patients underwent RSB: 11 patients with RAIR absent/unclear, 4 noncooperative children and 2 patients with ineffective medical treatment at follow-up. HD was diagnosed in 2 patients and laparoscopic-assisted ERPT was performed. The remaining patients had good results at 6-month follow-up. CONCLUSION ARM is a noninvasive diagnostic tool to study the mechanism of defecation in children with constipation in order to prescribe the appropriate treatment. This procedure can be used in every child - aged more than 1 year - with severe constipation and assessment of the RAIR can select the cases for RSB.

Abstract
Retroiliac ureter is a rare congenital anomaly. In this paper, we present a case in which retroiliac double ureters were incidentally found during a retroperitoneoscopic nephroureterectomy procedure in a 5-year-old boy with dysplastic right kidney in duplex system and ureterocele. Ureters were both in the retroiliac artery position. The nephroureterectomy procedure was completed retroperitoneoscopically. After a literature review, this case appeared to be the first report of retroiliac double ureters in a duplex system.

Abstract
Pneumoperitoneum (PN) and the gas used to insufflate the abdominal cavity during laparoscopy seem to be responsible for local and systemic modifications. The aim of this study was to verify the effects of intra-abdominal carbon dioxide (CO(2)) and air insufflation on the peritoneum, as well as the cortico-surrenal response in prepuberal rats. Sixty prepuberal rats were divided into three groups: in the first (S, n = 36), PN was induced with CO(2), whereas in the second (A, n = 14), it was induced with filtered room air; in both conditions, insufflation lasted 30 min at a pressure of 10-12 mmHg. The third group (C, n = 10), underwent general anesthesia only. Two hours after inducing anaesthesia, 12 rats in group S, 6 in group A and 6 in group C were killed and the remaining, after 24 h; specimens of the visceral and the parietal peritoneum were obtained for histological examination, blood sample was taken for cortisol and DHEA-S assays at the different study periods. At the histological examination performed 2 h later, the groups S and A presented inflammatory cell infiltrate in the parietal and visceral peritoneum; this finding was even more marked in group A, which presented also congestion, hemorrhage and disruption of the cell line. Twenty-four hours after the experiment, the peritoneum of the two insufflated groups presented chronic infiltrate and reactive mesothelial cells with congestion, which was more evident in group A, but totally absent in group C. Cortisol levels were significantly higher in groups S and A (2.15:1 ratio) killed 2 h later compared to those killed 24 h later and to the control group. DHEA-S levels were not significantly different between the groups. Our results demonstrate that the chemical, physical and molecular impact of CO(2) on the peritoneum causes inflammation and tissue damage, this was even more evident 24 h after our experiment and in the air insufflated group. PN induced a significant variation in blood cortisol levels at 2 h. The CO(2) insufflation should be limited in patients with pre-existing peritoneal damage.

Abstract
Neonatal adrenal hemorrhage may rarely present as scrotal hematoma. This condition can simulate a torsion of the testis requiring an immediate surgical exploration of the scrotum. Ultrasonographic study of the abdomen can find out intraperitoneal or retroperitoneal bleeding in order to avoid unnecessary surgical intervention. The case of a newborn with right adrenal hemorrhage presenting as left scrotal hematoma is reported.

Abstract
AIM To verify the efficacy of botulinus toxin A (TB-A) in treating children with neuropathic bladder secondary to myelomeningocele (MMC) with detrusor hyperactivity/low compliance, resistance to pharmacological therapy, and candidates for enterocystoplasty. METHODS From January 2002 to June 2003, a group of 7 patients was selected (4 females, 3 males, mean age, 9.8 years, age range, 5-17 years) with detrusor hyperactivity, clean intermittent catheterization and resistance to pharmacological therapy. Two patients presented with grade 2-3 monolateral vesicoureteral reflux (VUR). All patients were incontinent despite catheterization. Botulinus toxin A was administered under general or local anesthesia by the injection of 200 IU of toxin diluted in 10 cc of physiologic solution with a metal or a flexible needle (3.7 F/21 GA). The needle was fully inserted into the detrusor muscle in about 20 sites, and 0.5 cc of solution were injected in each site, except the trigonum vesicae. Follow-up included ultrasound examination of the urinary tract and urodynamic studies performed at 6, 12 and 24 weeks and biannually thereafter. Micturition cystography was performed 3 months after the intervention. Urodynamic parameters were leak point pressure (LPP), leak point volume (LPV) and specific volume at 20 cm H2O pressure. The results were analyzed using the Wilcoxon test. RESULTS A significant increase in LPV (range, 30-108%, mean, 77.6%) and in specific volume at 20 cm H2O pressure (CS 20) was observed in all patients. No significant change in LPP was found. One patient previously treated with the Cohen reimplantation technique experienced transient VUR which resolved spontaneously within 1 month. No major side effects from the injection of TB-A occurred. All patients were hospitalized for 24 hours with catheterization. CONCLUSIONS The preliminary results in this small sample of patients suggest that the use of TB-A is efficacious in significantly improving urodynamic parameters and urine storage volume at low pressures in patients with neuropathic bladder resistant to pharmacological therapy.

Laparoscopic Fowler-Stephens procedure is contraindicated for intraabdominal testicular major duct anomalies. Surg Endosc 2004.

Abstract
The laparoscopic one- and two-stage Fowler-Stephens procedure has gained large popularity in the treatment of the child with a high intraabdominal testis. It is largely debated which technique (e.g., testicular autotransplant or Fowler-Stephens procedure) offers the best results for high intraabdominal testes. We describe a case of a 3-year-old boy for whom previous bilateral inguinal exploration results were negative for testes or testicular remnants. The diagnostic laparoscopy showed two iliac intraabdominal testes with short spermatic vessels, closed inguinal rings, and complete dissociation of didime-epididime. A left open orchidopexy was perfomed, and testicular autotransplant was proposed for the right testes located 4 cm from the internal inguinal ring. Long-term follow-up evaluation (1.8 years) of the left testis showed it in the scrotum with good testicular size (1.5 cm). We believe that there are two main reasons to contraindicate the Fowler-Stephens technique: associated malformation that does not permit the development of the collateral blood flow via the vasal artery necessary for a viable testis, and previous surgery that represents a risk factor for testicular atrophy. The laparoscopic anatomic classification for the intraabdominal testis is reliable and can disclose the most suitable surgical technique. Laparoscopy is a valuable tool in the diagnosis and treatment of the nonpalpable testicle.
