Abstract
AIM Primary gastrointestinal perforations have an incidence of between 1% and 3% in NICU patients. The 3 Centers participating in this study cover nearly 40% of the NICU population of the Lazio Region--Italy. The aim of this study is to discuss factors affecting survival in patients affected by a primary intestinal perforation. METHODS From 1991 to 2001, 67 cases of 85 with a neonatal gastrointestinal perforation, were related to primary bowel lesions. Necrotizing enterocolitis (NEC) was not always the cause of perforation and in many patients an isolated bowel lesion without signs of NEC was found. The aim of this study was to examine clinical and intraoperative findings of NEC and non NEC perforations and their impact on survival. A relevant number of these patients were extremely low-birth weight (ELBW). Controversies about treatment of this category of neonates are discussed. RESULTS Patients were 37 males and 30 females (mean birth weight 1 274.8 g, mean gestational age 28.9 weeks, mean age at perforation 10 days). Overall survival was 56.8%. Patients were divided by intraoperative findings in 2 groups: NEC (n=48), or isolated intestinal perforation (IIP) without signs of NEC (n=19). Differences between these 2 groups with regard to birth weight, maturity, associated cardiac anomalies (patent ductus arteriosus, PDA) were significant. NEC and IIP behaved as 2 distinct entities, each with peculiar clinical (age at perforation, oral feeding, need of ventilatory support) and radiological aspects. At surgery, multiple lesion on necrotic bowel were typical of NEC versus single, isolated perforations on healthy bowel typical of IIP. Overall survival was almost identical in the 2 groups (59% vs 58%). ELBW patients (55% of the total neonatal intestinal perforations) were also studied. There were 21 patients with NEC and 16 with IIP. The 2 groups were different in age at perforation, previous oral feeding and associated cardiac anomalies (PDA). Overall survival was 62% for NEC and 50% for IIP. A laparotomy was always performed. Temporary peritoneal drainage was done in 4 cases only. Results were better when intestinal diversion was performed rather than resection and primary anastomosis. Almost all NEC patients had multiple perforations and extended bowel necrosis. CONCLUSION NEC is the most frequent cause of neonatal intestinal perforation. This is a quite distinct entity from IIP, which must always be differentiated preoperatively and which is most frequently found among low birth weight newborns. As far as surgical treatment of perforation among ELBW neonates is concerned, peritoneal drainage might be reasonably performed when a single lesion on healthy bowel as in IIP is clearly diagnosed but it could be inadequate for NEC patients.

Abstract
Bilateral renal vein thrombosis after an appendectomy has never been reported in the pediatric literature. We describe the case of a 10-year-old boy who developed this very unusual complication following appendectomy for gangrenous appendicitis with peritonitis. Color duplex Doppler is the most appropriate investigation to allow correct diagnosis and immediate medical treatment. Peritoneal dialysis is a simple and effective tool to prevent permanent damage to renal function.

Abstract
We describe the case of a 6-year-old boy who presented post-renal anuria and renal failure five days after appendectomy and drainage of a periappendicular abscess. Only mild dilatation of the urinary tract was observed on ultrasound and small calculi were documented at the ureterovesical junction bilaterally. Diuresis was restored by the insertion of uretercatheters. Awareness of this complication and immediate treatment can avoid permanent impairment of renal function.

Abstract
BACKGROUND Bladder autoaugmentation uses partial detrusorectomy to create a diverticular bulge in the bladder mucosa. This technique has eliminated certain serious complications of cystoplasty with gastrointestinal tissues (e.g., fluid/electrolyte/acid-base imbalances, mucous hypersecretion), but the exposed mucosa is subject to fibrosis and, sometimes, to perforation, which can annul the benefits of surgery. METHODS We have developed an original technique based on traditional autoaugmentation with protection of the herniated mucosa by split-thickness pedunculated rectus abdominis muscle flaps that are sutured to the incised margins of the detrusor. Preliminary testing was done on 30 adult Wistar rats. A control group of 15 rats underwent laparotomy alone. Bladder capacity was measured via suprapubic cystography before and after (4 weeks, 8 weeks, 1 year) surgery, just before sacrifice. Sections of the reconstructed bladder were examined histologically. RESULTS Twenty-three bladder-augmented rats and 13 controls survived. In the experimental group, bladder capacity increased by 38% (mean). None of the rats experienced urinary retention, although one developed bladder stones. Histology revealed no pathologic changes (other than chronic inflammatory infiltrates at suture sites) in the mucosa, detrusor, or muscle flaps, which were all viable and well integrated by the fourth postoperative week. There were no signs of mucosal or muscle fibrosis. CONCLUSIONS Preliminary results in a rat model suggest that this new technique can produce an enlarged bladder that is fully functional and less vulnerable to fibrotic retraction and rupture. Residual contractility in the muscle flaps might theoretically be exploited to facilitate paraphysiologic micturition.

Abstract
Several studies indicate that in young patients (less than 21 years of age at the time of diagnosis), the prognosis of thyroid carcinoma (TC) is more favorable than in older patients. However, a more radical treatment approach is recommended in children and adolescents due to the higher prevalence of local lymph-node involvement in these cases. Since the extent of primary surgical treatment is closely related to the overall prognosis, preoperative diagnosis becomes essential in the management of thyroid neoplasms in young patients. In this retrospective study (1987-1998), we analyzed a surgical series of 50 children and adolescents with thyroid nodules in an attempt to establish the role of diagnostic studies in detecting malignant lesions prior to surgery. Our diagnostic protocol for evaluating thyroid nodules was based on clinical evaluation, measurement of thyroid-hormone and thyroglobulin (TG) levels, anti-TG and anti-TPO antibody titers, calcitonin, CEA, and TPA levels, sonography, scintigraphy, and fine-needle aspiration cytology (FNAC) of the thyroid nodules and any enlarged lymph nodes. Eleven of the 15 cases of histologically confirmed carcinoma were preoperatively identified as malignant lesions with the aid of FNAC. The authors conclude that the preoperative work-up of children and adolescents with thyroid nodules requires the collaboration of an experienced team of professionals, and recommend FNAC as the initial test.

Abstract
PURPOSE We evaluated the feasibility of urethroplasty using a free peritoneal graft in a rabbit model. MATERIALS AND METHODS In 12 male rabbits a urethral defect was created by excising a 3 x 5 mm. portion of the ventral urethral surface. The defect was immediately repaired with a free peritoneal graft harvested via a left flank incision. RESULTS There were 2 intraoperative deaths and 1 death on day 8 postoperatively. These animals were excluded from study. The remaining 1, 4 and 4 rabbits were sacrificed 3, 5 and 9 weeks after surgery, respectively. Macroscopic examination of the urethra revealed no stenosis or diverticula, while a fistula was present in 3 of the 9 animals. Histological study of the fistulous tracts showed chronic granulomatous inflammation. In the remaining 6 rabbits there was graft adherence. The inner surface of the graft was uniformly lined with normal urothelium, while in some cases acute inflammatory cells were present in the subepithelial layer. CONCLUSIONS Our experience indicates that the ease of harvesting free peritoneal grafts and their satisfactory adherence to the urethra makes them a valid alternative for repairing urethral defects.

Abstract
OBJECTIVES The best therapeutic approach for varicocele correction in pediatric patients is still an object of some debate. We analyzed a series of 99 patients to identify the most effective approach in terms of low recurrence rates and preservation of testicular growth. METHODS One hundred four operations were performed on 99 patients between 9 and 16 years of age (mean 13.3). The first 18 patients underwent sclerotherapy of the internal spermatic vein. Twenty others underwent inguinal varicocelectomy. In 12 patients, a modified Palomo procedure (ie, sparing of the internal spermatic artery) was performed (four laparoscopically), and 54 were treated with the original Palomo procedure (ie, sectioning of the entire spermatic cord), using laparoscopy in 20. RESULTS Three recurrences (16.6%) occurred among the patients treated with sclerotherapy. Similar rates of recurrence were observed in those who underwent inguinal varicocelectomy (3 [15%] of 20) and modified Palomo procedures (2 [16.6%] of 12). Only one recurrence occurred in the 54 patients treated with the original Palomo procedure (1.85%). CONCLUSIONS Our experience, together with a review of published reports, leads us to believe that the open Palomo procedure as originally described is the most effective approach to the correction of varicoceles in adolescents.

Abstract
We describe a case of H-type rectovaginal fistula associated with the Currarino triad (anorectal stenosis, sacral defect, presacral mass). Presenting symptoms included passage of feces per vaginam, signs of intestinal subocclusion without perianal inflammation, left leg paresis and foul-smelling urine. An anterior sacral meningocele was repaired at the age of three months. At age 18 months the fistula was excised through a perineal approach after creation of a protective colostomy. Diagnostic and therapeutic aspects of this malformation are discussed.

Abstract
A total of 46 testicular biopsies were examined to define the histological characteristics of undescended testicle. Nine of the biopsied organs were normally positioned testicles from deceased pediatric patients (aged 2 months-14 years), and the remaining 37 were undescended testes from children with various degrees of cryptorchidism (aged 18 months-14 years). As reported by others, the degree of histological damage was directly proportional to the age of the subject. Close correlation between histological findings and the level of descent was not observed.

Abstract
The approach to nonpalpable testis is probably the most important indication for laparoscopy in pediatric surgery. In abdominal testis, spermatic vessels can be too short to allow for standard orchidopexy. The division of the spermatic vessels proposed by Fowler and Stephens may result, in some cases, in testicular hypotrophy or atrophy from intraoperative devascularization. In this study, we report our experience of two-stage laparoscopic orchidopexy, first proposed by Bloom. Five patients (ages 2-10 years) were treated with this technique. Laparoscopic inspection and division of spermatic vessels were successful in all patients, with no complications. Orchidopexy was performed at an average of 6 months from the first operation. During a follow-up period of from 6 to 18 months, no patient developed atrophy or hypotrophy of the testis.

Abstract
The purpose of this study was to analyze the preliminary results obtained with endoscopic treatment of children with chronic idiopathic pancreatitis. The disease appears to be caused by a deficit of pancreatic stabilizing proteins that leads to precipitation of solutes contained in the pancreatic secretions; these precipitates are the cause of inflammation. The possible role of a congenital malformation in the pathogenesis of this disease is being regarded with increasing scepticism. Between October 1991 and April 1994, five cases of chronic pancreatitis were referred to the Division of Pediatric Surgery of the Policlinico "A. Gemelli" of Rome. The age range of the patients (3 boys, 2 girls) was 3 to 14 years (mean, 10.8 years); all had a history of acute attacks and had blood chemistry findings compatible with pancreatitis. None of the patients' families had a history of pancreatic disease. All diagnoses were confirmed by endoscopic retrograde cholangiopancreatography, and the disease was staged according to the criteria of Cremer et al. Endoscopic pancreatic sphincterotomy, with or without removal of calculi, was performed in four cases (2 in the authors' hospital, 2 in another institution). Three of the children have had no further symptoms (mean follow-up period, 20 months), and their growth and weight gain have been normal. The fourth child, a 3-year-old girl, has had two episodes of pain since treatment. These attacks, both of which subsided spontaneously, probably were caused by the passage of protein plugs through the sphincterotomy. The fifth patient received no treatment because she had remained asymptomatic since the first examination (28 months ago). The short-term effects observed in these children indicate that endoscopic treatment of chronic idiopathic pancreatitis is associated with a high rate of success with respect to pain control. Because of the short follow-up, the effects on endocrine and exocrine function have not been assessed. No deaths or complications occurred. Conservative treatment of this type can be repeated if pain recurs, an important factor given the chronic nature and early onset of this disease, and it does not preclude the possibility of subsequent surgery. The authors' experience indicates that this approach should be considered the initial treatment of choice for children with chronic pancreatitis.

Abstract
Intraosseous arteriovenous fistulas of the extremities are rare malformations frequently associated with severe systemic hemodynamic alterations. In many cases, it is quite difficult to eliminate these anomalous vascular structures, but the possibilities for successful treatment are much greater when surgery is combined with interventional radiology. Selective embolization of the malformed vessels can be produced with a variety of agents that are injected into afferent arteries, via percutaneous puncture or through direct surgical access. The intraosseous portion of the fistula should be resected at the time of embolization or later. The authors describe the successful treatment of three patients having intraosseous arteriovenous fistulas of the upper extremities, who have had follow-up for 2 to 10 years.

In spite of emergency treatment the child expired shortly after admission. Our observation of this case prompted a review of the literature on the treatment approaches currently used for these tumors. Emphasis is placed on the necessity for early treatment in order to avoid infectious complications that, if neglected, can lead to unmanageable and possibly fatal sepsis.

Abstract
Advantages of primary fascial closure of abdominal wall defects are mainly in reducing the number of staged procedures with related complications and the need of multiple operation. Nevertheless correction of large defects still remains a challenge to pediatric surgeon. Postoperative paralysis and mechanical ventilation after intraoperative milking of intestinal content and abdominal muscles stretching have been reported to reduce the risks of "forced" primary closure. A series of 64 Omphalocele and Gastroschisis has been reviewed. Associated anomalies are still the main cause of mortality among Omphalocele. Prematurity plays a secondary role on survival of Gastroschisis cases; deaths were mainly due to sepsis. Primary respiratory insufficiency affected a large number of Giant Omphalocele cases (larger than 5 cm with herniated liver) and was associated to a restricted chest structure. All these cases died in the first weeks of life. Primary closure with or without postoperative paralysis and mechanical ventilation showed to reduce in a significant way the postoperative complication rate compared to staged procedures. Mortality and hospital stay were not significantly influenced by different kinds of surgical treatment among Omphalocele. Associated anomalies are an unavoidable limiting factor to survival. Among Giant Omphalocele the use of aggressive primary fascial closure with ventilatory support showed in our hands to be a safe procedure provided that a preoperative selection of cases on the basis of chest X-ray and blood gases has been made.

Abstract
Dumbbell neurogenic tumours are unusual neoplasms in the pediatric age group. Six cases all in children under 10 years of age, have been reviewed with respect to diagnosis, management and results. Neurologic deficits have been found in 4 patients only; in the other 2 cases the tumours were occasionally discovered. Myelograms, sometimes associated with CT scan, allowed a correct diagnosis in all the patients. Initial treatment consisted in all the cases in laminectomy or laminotomy with total excision of the extradural tumour. The primary paravertebral tumours have been removed in one patient during the same neurosurgical operation, and in other three patients at a second stage. Two patients did not require the second operation: one recovered after chemotherapy and the other died few days after the first surgical procedure. Five patients are still alive: two, who had the tumour occasionally discovered, are free from disease; among the other 3 patients, presenting with neurological symptoms, 1 is free from disease without neurological symptoms and 2 have still long lasting sequelae. The authors emphasize the role of early diagnosis to prevent neurologic abnormalities and to achieve better results.

Abstract
We discuss data on urinary tract dilatations diagnosed in utero from February 1980 to May 1988. Over 8,900 pregnancies prenatally investigated with ultrasound during second and third trimester in our center. We diagnosed 401 fetal defects (4.5%) with 121 urinary system anomalies (1.35%). In 90 cases (1.01%) urinary tract dilatation was present, representing the most frequent urinary pathology in utero (74.3% of all urinary anomalies). We describe some diagnostic findings as particularly useful in differential diagnosis of functional and obstructive conditions, stressing the possibility and the difficulty of diagnostic accuracy for urinary tract anomalies. The perinatal outcome of each condition is reported.

Abstract
End stage liver disease in children can be treated with orthotopic liver transplantation (OLT). Nevertheless, the expansion of this therapy in Europe has been limited because of the shortage of appropriate size-matched donors. One possible technical solution is the OLT of a liver graft previously reduced in size by in situ resection preceding the harvesting procedure. To study the impact of this technique we examined two different operative procedures performed on Landrace pigs. Group 1 consisted of 20 standard donor/recipient weight matched OLT. In group 2, 15 OLT were performed using right lateral and medial lobes (55% of the original donor liver). The donor/recipient weight ratio in the group was 2:1. Cold ischemia times were 90 +/- 16 min for group 1 and 98 +/- 9 min for group 2. It is emphasized that in contrast to all the other reports using resected liver grafts for OLT, the donor resection in our study was always performed in situ under normothermic conditions, preceding the harvesting procedure. This was designed to reduce the cold ischemia time. No significant technical problems were encountered. The biochemical results of group 2 pigs compared to group 1 demonstrate an analogous, postoperative course. This might be explained by regenerative stimuli acting on the resected liver tissues and enhancing their metabolic function. These data support the conclusion that resected adult donor liver grafts may be used for pediatric transplant recipients.

Abstract
Despite prenatal diagnosis, maternal transport and early perinatal treatment in specialized hospitals, improvement in overall mortality has not been observed among newborns with abdominal wall defects (omphalocele and gastroschisis). A comparison has been made, for both anomalies, between 55 cases treated in the periods 1967-1979 and 30 treated in the periods 1980-1985. In this last group 14 prenatally detected cases were separated from cases discovered at birth. Recent advances in treatment have reduced mortality rates for both of these anomalies. This was especially true for gastroschisis; in omphalocele cases, associated abnormalities appeared to be an unavoidable limiting factor in survival. With prenatal diagnosis a surprising increase in mortality rate was observed among omphalocele cases detected before birth. A possible reason for this is the total number of antenatally diagnosed cases that, with maternal transport, are concentrated in centers where surgical facilities are available. Before introduction of antenatal diagnosis, most of these cases would never have been observed by the pediatric surgeon because of death prior to referral or treatment. Gastroschisis cases may benefit more from antenatal recognition and early treatment because multiple abnormalities or immaturity are not so important limiting factors in survival as in omphalocele cases. Reduced trauma and contamination of exposed viscera, immediate treatment and adequate supportive measures may significantly reduce mortality rate in gastroschisis cases. Operative delivery of fetuses with an abdominal wall defect is controversial. The risk of vaginal route delivery has been over emphasized. Intrapartum rupture of an omphalocelic sac was an extremely rare event before introduction of antenatal diagnosis.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Appropriate management of fetal uropathies depends on accuracy in assessing the severity of urinary tract obstruction and renal damage, and in predicting the potential for recovery after surgical correction. A review of 40 fetuses aged between 20 an 39 weeks referred to us for prenatal counseling for a suspected anomaly of the urinary tract, has been made. Reliability of our diagnostic resources has been retrospectively evaluated on the basis of clinical, ultrasonographic and radiological postnatal data. Conservative approach has been adopted in all our cases. None intrauterine surgery was attempted; pre term delivery was advised only in two cases. Our results confirm poor prognosis of fetuses with marked decrease of amniotic fluid within the 24th week of gestational age. After this date the amount of amniotic fluid alone may not be a completely reliable prognostic factor. Ultrasonographic aspect of fetal kidneys and, in some occasions, chemical analysis of fetal urines may accomplish our prenatal study and help to predict the degree of neonatal renal function and potential of survival.

Abstract
Nine cases of fetal intrathoracic anomalies detected in utero and followed to birth are reviewed. There were 6 congenital diaphragmatic hernias (CDH), one congenital pleural effusion and two isolated cysts of the lung. All these conditions were potentially responsible for neonatal respiratory distress and received early intensive treatment after maternal transport and delivery had been arranged in a center with thoracic surgical facilities available. The risks of a delayed or missed diagnosis were thus avoided, especially for CDH. Despite intensive, traditional, respiratory support, started in the delivery room, mortality among prenatally detected cases of CDH was paradoxically high (83%), compared to mortality among 7 cases of CDH not detected in utero, referred in the same period to our Institution, and symptomatic within 6 h from birth (63%). With prenatal diagnosis the total number of CDH cases referred to a surgical center before birth increases. Many cases which would never have been treated in the past because of death before referral and treatment for severe pulmonary hypoplasia not compatible with life are thus observed and sometimes treated. Nevertheless, lung development continues to be a determining factor for survival even when intensive treatment at birth is available. Responsiveness to therapy is unpredictable before birth and proposed antenatal treatment is still far from being a realistic option. For the other three newborns, where a pleural effusion and pulmonary cysts were found, prenatal diagnosis helped to start appropriate treatment and to prevent neonatal hypoxia in two of them. In the third case, with an incommunicant, isolated pulmonary cyst, the outcome would have been favourable even without a prenatal diagnosis.

Abstract
The authors report on clinical experience from 20 infants who were under six months of age, and who had been referred during the last five years for pelvi-ureteric junction obstruction. Any over-eagerness to arrive at an early diagnosis, mostly on the basis of prenatal ultrasonographic suspicion, must be tempered. Pyelocaliceal dilatation in newborn infants may not be related to obstruction, and overtreatment must be avoided by careful preoperative evaluation. Tc-DTPA diuretic computerised renography proved extremely reliable, whereas IVP may be unsatisfactory and misleading. Whenever surgical correction was indicated for a documented pelvi-ureteric junction obstruction, Anderson-Hynes pyeloplasty was performed, except in one case, where severe dysplastic changes in the hydronephrotic kidney necessitated nephrectomy. Splinting of the anastomosis was adopted in newborn with thin ureters. An infant with left pelvi-ureteric obstruction and right multicystic kidney died from renal failure a few days after right nephrectomy and left pyeloureteroplasty. No operative failure was otherwise observed, except for a transient anastomotic obstruction in two cases. Treatment of pelvi-ureteric obstruction in the first 6 months is a serious undertaking and should be restricted to experienced centres with facilities for intensive neonatal care, even for dialysis.

Abstract
Results of US study in 30 children with various renal lesions are reported, and compared with clinical and surgical features. Different ultrasonographic aspects are discussed with special interest on cogenital abnormalities. US is proposed as first choice investigation in newborns with antenatal ultrasonographic demonstration of renal lesions and in all patients where a mass of renal origin is suspected. Renal function, nevertheless, must be investigated with radiologic and/or radioisotopic techniques. US have still a large indication in short term follow-up of renal lesions where surgical treatment is not indicated.

Abstract
A large series of malignant and benign conditions are generally collected under the term of abdominal masses. Their common aspect is the lack, in most of the cases, of peculiar clinical features which may help early differential diagnosis. In many cases the mass is detected late after a long period of vague, aspecific symptoms. 40% of these space occupying lesions of the abdomen are of malignant origin and delayed detection and investigation affect clinical course. Preoperative study of abdominal masses is a problem of primary importance in pediatric surgical practice. A changing attitude is registered towards many diagnostic procedures and the role of largely diffused techniques like angiography is controversial. The introduction of ultrasonography makes in many cases intensive radiologic investigation unwarranted and academic. The Authors discuss the real role and targets of preoperative investigations of abdominal masses and refer on their experience based on 52 cases, to underline some clinical aspects and analyse their diagnostic approach to this pathology.
