Introduction: Recurrent tracheoesophageal fistula (RTEF) is a frequent complication (5-10%) in patients with esophageal atresia (EA). Open RTEF surgery has a high morbidity and mortality, so the endoscopic approach represents a promising alternative. We present the long-term results of fibrin glue (FG) bronchoscopic application in patients with RTEF secondary to EA, which was first used by our team in 1994., Material and Methods: A retrospective review of all patients diagnosed with RTEF following EA repair and treated with FG bronchoscopic application from 1993 to 2019 was carried out. In most cases, diathermy was applied prior to FG sealing. The maximum number of endoscopic sessions was 5. In case of persistent RTEF following the fifth session, open surgery was performed., Results: 14 RTEF patients were treated with FG. In all but the first 3 cases (11 patients, 78.6%), diathermy was applied concomitantly. Mean first treatment day was day 85 of life (range: 14-770). Patients received a mean of 2.1 (1-5) endoscopic sessions. Mean follow-up was 12.1 (10-20) years. Overall success rate was 71.4%, without significant differences according to whether diathermy was concomitantly applied or not (72.7% vs. 66.6%)., Conclusions: Fibrin glue bronchoscopic application associated or not associated with diathermy is an excellent option for RTEF treatment in EA patients. The endoscopic approach should be considered as the first-choice treatment for RTEF.

Introduction  Low values of esophageal impedance baseline (EIB) have been related to esophagitis. The aim of this study was to evaluate the diagnostic performance of EIB for erosive esophagitis (ErE) and histological esophagitis (HiE) in children studied for gastroesophageal reflux. Material and Methods  Children who underwent esophageal multichannel intraluminal impedance-pH monitoring (MII-pH) and upper-endoscopy with esophageal biopsies were studied retrospectively. EIB values were obtained by MII-pH. ErE was assessed by endoscopy following the Hetzel-Dent classification; HiE was defined by basal zone hyperplasia, papillary lengthening, or inflammatory infiltration. EIB was compared between groups. Receiver operating characteristic (ROC) curves were obtained to calculate the global diagnostic performance of EIB and to find cut-off values for sensitivity and specificity. Logistic regression was used for age adjustment. Results  Fifty-one patients were studied: 11 had ErE and 23 had HiE. EIB median values were 1,159 in ErE versus 2,583 in non-ErE (U = 80, p  < 0.01). The adjusted ROC curve analysis for ErE was 0.85 (95% CI = 0.74-0.96); the EIB cut-off value = 2,379 determined sensitivity = 100% and specificity = 52.6% in children < 4 years old. and sensitivity = 100% and specificity = 63.2% in children > 4 years old. EIB median values were 1,666 in HiE versus 2,669 in non-HiE ( U  = 80, p  < 0.01). The adjusted ROC curve analysis for HiE was 0.75 (95% CI = 0.59-0.90); the EIB cut-off value = 2,296 determined sensitivity = 71.2% and specificity = 83.1% in children < 4 years old, and sensitivity = 75.1% and specificity = 80.1% in children > 4 years old. Conclusion  EIB provides statistically significant diagnostic performances for ErE and HiE. It could become a useful tool, especially to discriminate between ErE and non-ErE, avoiding other invasive tests., (Georg Thieme Verlag KG Stuttgart · New York.)

The aspiration of a foreign body remains a common paediatric problem, with serious consequences that can produce both acute and chronic disease. Aspiration usually causes a medical emergency that requires a prompt diagnosis and an urgent therapeutic approach as it may result in the death of the child or severe brain injury. It typically involves organic foreign bodies (mainly food or nuts) aspirated by children under 5 years old, and usually at home. In this statement, the Committee on Safety and Prevention of Non-Intentional Injury in Childhood of the Spanish Paediatrics Association provides a series of recommendations, both educational (while eating and playing), as well as legal, to prevent such episodes., (Copyright © 2016 Asociación Española de Pediatría.

PURPOSE. To submit the short and long term results of long-gap esophageal atresia (EA) with two surgical techniques. METHODS. We carried out a retrospective study of long-gap type EA without fistula (n=8) and with fistula (n=2) over the last 18 years, comparing the outcome of the Schärli technique (1992) with that of the Foker technique (1997). RESULTS. We included 10 patients with long gap EA. Mean birth weight was 2,418 grams. 30% had associated diseases (VACTERL, Down Syndrome, DiGeorge Syndrome). Gastrostomy or jejunostomy was initially placed in 7 patients. Schärli technique was performed in 4 patients (mean age: 3.3 months), and Foker technique in 6 patients (median age: 23.5 days of life). Complications were: a) Schärli: dehiscence (25%), stenosis (75%), one patient died from his heart disease (25%), colonic herniation through diaphragmatic hiatus (25%). The mean number of stricture dilatations was 7 sessions (S.D. 9.2). a) Foker: dehiscence (83.3%), stenosis (83.3%), gastroesophageal reflux (GER) (83.3%), fistula (16.7%). Mean number of dilatations was 13.7 sessions (S.D. 12.8). All patients operated on with Schärli technique (6-18 years, median follow-up 12 years) were asymptomatic at the time of the study, although one of them had grade III esophagitis in the last biopsy. As for the Foker's, 5 had undergone antireflux surgery and only one was asymptomatic. The rest had complications that were still being treated (stenosis and development of fistulae). CONCLUSION. Treatment of long gap EA remains a surgical challenge. In our experience patients developed fewer complications with the Schärli technique. Nevertheless, it is difficult to make a comparison with such a limited number of patients.

Introduction: Kasai's operation has proved its value in surgical treatment of biliary atresia (BA). Its laparoscopic approach is a new challenge for pediatric surgeons, with all the potential advantages of minimally invasive surgery. The aim of the present study has been to report our experience in laparoscopic management of five patients with biliary atresia., Patients and Methods: The average of age of five patients with biliary atresia, three boys and two girls was 58 days (range 40-64). Pre and postoperative management included antibiotic prophylaxis and choleretic treatment. Laparoscopic procedure was accomplished using one umbilical 10-mm trocar and two additional 5-mm trocars. We carried out the same technique in all the patients except in one of them with a total situs inversus and who compelled us to modify the original procedure., Results: All five patients underwent a laparoscopic procedure, conversion was not necessary. The mean surgical time was 3 hours and 40 minutes (range: 5:30 y 3:10). There were not intra operative complications and all of them had a satisfactory recovery, except for the patient with situs inversus, who suffered a small bowel volvulus 9 days after the operation, leading us to perform an extensive bowel resection. All the patients, except this one, showed signs of adequate bile flow, with disappearance of clinical cholestasis. Biochemistry test became normal., Conclusions: Besides the certain advantages compared with conventional surgical procedures (lower surgical damage, diminished post-operative recovery), laparoscopic management of BA, allows a better exposure of the porta hepatis without hepatic mobilization so it shows similar or better preliminary results than conventional techniques. The advantages of laparoscopic portoenterostomy are yet to be proved whenever liver transplantation is indicated.

Unlabelled: The aim of the present study has been to systematize the clinical presentation of the entity named choledochal cyst, in relation with its probable etiopathology and the intraoperative findings as well as its evolution after surgery, based on the revision of the literature and of our experience in 29 cases., Material and Methods: 29 cases of cystic dilatation of the biliar duct extra and/or intrahepatic are analyzed. In 4 cases the diagnosis was prenatal and two were excluded of the study after it has been confirmed they suffered biliary atresia type I. In the left 27 cases, 19 variables are analyzed retrospectively, like age, sex, weight, symptoms, ultrasonographic images, etc. Subsequently, intra-operative cholangiographic findings were correlated with the clinic presentation and the evolution of the patients after surgery., Results: Of the 27 cases analyzed 16 (59,25%) were cystic dilatations from which 14 had a neonatal or early clinic presentation (before 2 years), however the fusiform dilatations were presented later on. From the analyzed symptoms, in relation with the age only the pain and the jaundice showed significant differences, being the pain most frequent in later presentation ande the jaundice in the early form. The two cases of type 3 of Todani or choledochocele were of later presentation. An anomaly in the bilionpacreatric junction was detected in 15 patients; the majority had a later presentation, associated to pancreatitis in 4 cases. Primary cyst excision and biliary Roux-en-Y reconstruction was the treatment of election in the majority of cases. In 3 cases we used the appendix to replace the choledocus, but all three cases were reconverted two years later because of permanent elevation of ALT and GGT., Conclusions: In favour of the literature and of our experience nowadays it would be possible to systematize this malformation and make a division in two groups, depending on the cholangiographic findings and clinical presentation: 1. Cystic dilatations with a clinical neonatal presentation or beneath 2 years. 2. Fusiform dilatations with a later clinical predominance and associated frequently to pancreatitis and anomalous pancreatobiliary junction. Choledochocele is an entity that must be considered not only for its etiology but for its clinical presentation and treatment. Primary cyst excision and biliary Roux-en-Y reconstruction is the treatment of election. Regular long-term review of these patients is mandatory in the surveillance of sub-clinic cholangitis and the risk of possible long-term malignance of this entity.

Introduction: Pediatric surgical literature is characterized by a high prevalence of observational studies and a paucity of randomized controlled trial, comparing mainly medical therapies., Aims: To asses scientific evidence level produced by spanish pediatric surgeons., Material and Methods: Articles reported in Cirugía Pediátrica, surgical reports in Anales Españoles de Pediatría, and reports from spanish authors published in the Journal of Pediatric Surgery, Pediatric Surgery International and European Journal of Pediatric Surgery, from 1997 to 2002. Internal validity was assessed through the critial guides from Sackett, and evidence level was classified through the Oxford Centre for Evidence Based Medicine classification., Results: 94.5% on therapy reports, 61.5% on diagnosis, 83.3% on prognosis and 52.2% on risk factors or etiology, were classified as level 4 (descriptive studies). Only four randomized controlled trials were found, all of them comparing medical therapies (analgesia, antibiotics and surgical stress control)., Conclusions: Our results are similar to those offered by previous reviews, showing up a low level of scientific evidence in most articles. Diffusion of guides on reporting descriptive studies may improve the evidence level of our reports.

Within the last ten years and by the introduction of some new instruments, laparoscopy is a safe and effective method that has been further extended in children. We report our experience in the treatment of laparoscopy on a seven day old newborn affected by malrotation with an intermittent duodenal obstruction. The treatment consisted of a duodenal liberation after the section was easily performed in congenital Ladd's bands. The spiral twists of the small intestine found in the upper gastrointestinal series, disappeared in a new study done after surgery. We consider this operation as a new indication for an operative laparoscopy. It allows a good visualization of this congenital abnormality, and it is easy to perform with a significantly reduced operative trauma.

This report details our preliminary experience with hepaticoporto-appendicostomy in three patients with biliary cystic disease. The surgical procedure was total resection of choledochal cyst and vascularized appendix interposition between biliary tree and duodenum. The children have been followed by clinical, ultrasonography and endoscopic (ECPR) during a period between 1-4 years. There was no episodes of ascending colangitis. All the patients remain free of jaundice and the biochemical abnormalities have become normal three months after interposition. Our results suggest that this procedure is more physiologic than the standard bilioenteric derivation Roux-in-Y, because allow bile to enter freely to duodenum and prevent reflux, stasis and ascending cholangitis. This procedure allows postoperative endoscopic valoration, not possible in another kind of bilioenteric derivations.

Injection of sclerosing solutions into the rectal submucosa or into the perirectal space is one of the many therapies designed to correct rectal prolapse. Since 1994, four patients affected with this condition have been treated with fibrin adhesive percutaneous injection. Up to now, this product had not been used to this aim. Age range was from 1 month to 8 years. The medium duration of prolapse prior to therapy was 19 months and three of them had an associated pathology (myelomeningocele, cystic fibrosis and severe psychomotor retardation). There were no post-injection complications. In one patient with an irreducible prolapse an anus encirclement with a rectal tube was associated. Except for this patient, the whole process take less than 24 hours. With a medium follow up of 11 months this therapy has resulted effective in three of our four patients. It has failed in a girl with severe psychomotor retardation.

Lymphangioma and venous angioma are a group of pathological entities which have required surgical treatment since years. Extension, localization and poor delimitation of some lesions have resulted in technical difficulties and serious complications. Our group began the sclerosing therapy with an injection of fibrin adhesive and, due to the lack of response in the first patient, a program with Ethibloc as an alternative substance was developed. We present 10 cases, 4 lymphangiomas and 6 venous angiomas. In 50% of our patients one single session of sclerotherapy was made, in 25% two sessions, and in the rest 25% three. From 10 cases, 4 are still on treatment, complete remission in 5 cases, and good evolution in one case (mixed lymphangioma). As a long-term complication, we have noticed fistulization in 3 cases, and expulsion of the sclerosing agent. In our experience, percutaneous sclerosis with Ethibloc should be the first therapeutic alternative.

We report a case of biliary atresia promptly detected by its association with a choledochal cyst, prenatally diagnosed at 20 weeks' gestation. The baby was operated at 14 days of life. A choledochal cyst was found and fibrosis of the extrahepatic bile ducts was also noted. So, excision of the choledochal cyst and a Roux-en-Y porto-jejunostomy was done. Nine months later, despite an appropriate biliary drainage, echographic and histological changes compatible with liver cirrhosis have been detected. Including this one, six cases have been reported.
