[Treatment of esophageal stenosis in children].

Esophageal stenoses, both congenital and acquired, represent a serious problem in childhood due to the deleterious effects, of these anomalies in the patients nutritional state and lifestyle. Choosing the best way to the solution of such problems is of primary importance, paying special attention to the techniques that may not compromise irreversibly the continuity of the alimentary tract. The authors experience on the treatment of 77 esophageal stenoses, 8 of which were congenital and 69 acquire, is reported. Of this group, 24 are sequelae of esophageal atresias, 33 are of caustic origin and 12 of peptic nature. In 3 congenital stenoses with a cartilaginous matrix, surgical repair was undertaken. In the remaining cases forward and retrograde dilatation guided by a thread, through the gastrostomy orifice were performed, in accordance to the length and severity of the stenoses. Duration of the treatment varied broadly, ranging from 3-5 anterograde sessions, in the cases of esophageal atresia sequelae, to several years with an average monthly periodicity of one session in cases of total pharyngoesophageal caustic burn. As for complications, there were three cases of mediastinitis and two of subcutaneous infiltrations at the cervical level that were solved with antibiotics. The authors believe, on the basis of their experience, the absence of mortality and the scarce morbidity that, in the pediatric patients the treatment of choice of esophageal stenoses consists of dilatations on their different modalities. A yearly follow-up must be strictly maintained until the patients have completed their growth. We reject esophageal coloplasties in the pediatric age because of their complications rate.(ABSTRACT TRUNCATED AT 250 WORDS)

[New perspectives in liver-based metabolic errors: liver transplantation].

Liver transplantation offers an actual alternative to patients end-stage liver disease. The aim of this study is to show our results of liver transplantation in paediatric patients with hepatic-based metabolic disorders. Survival rates in these indications can be high and these good results may enlarge the indications. Liver might transplantation therefore be offered earlier to patients with this kind of metabolic disease.

[Fistula of the pyriform sinus. Report of 2 cases].

The authors present two patients of 8 and 11 years of age that presented a left sided piriform sinus fistula diagnosed by esophagram and surgically treated in our centre. One had been operated previously with a diagnosis of relapsing thyroglossal quist on five occasions. The piriform sinus fistula is a recently recognised entity as cause of thyroiditis and suppurative cervical infections in the pediatric age. Communicated for the first time in the literature in 1957 by Japanese authors, it was not until 1973 that Tucker published for the first time in English a case of recurrent cervical abscess caused by a fistula initiated in the piriform sinus. Until now very few cases have been published. The majority of authors consider it to be an embryological residue of the third or fourth pharyngeal pouch. The key to diagnosis is to bear it in mind whenever a patient presents suppurative thyroiditis or repetitive cervical infections, principally of the left side. An esophagram is necessary to demonstrate the course of the fistula. In cases of thyroiditis a thyroidal gammagraphy will allow vision of a cold zone in the upper third of the affected lobe. Treatment consists of total extirpation of the fistula and affected portion of the thyroidal lobe, once the infection has been solutioned. Before intervention it is important to collocate a tube in the fistula's course by means of a direct microlaryngoscopy which will serve as guide and allow the injection of methylene blue.

[Bolande's tumor: significance of its early diagnosis and treatment].

Four patients diagnosed of having a tumor of Bolande and treated at our institution in the past ten years are presented. In two of them, early diagnosis was aided by prenatal echographic techniques; the other two diagnoses were suspected ar three and ten days of age because of an abdominal mass. The four of them underwent a complete study which included: a plain abdominal film, an ultrasound scan and an intravenous urogram; the last three patients were also surveyed by a CT scan of the abdomen. Surgery was undertaken early on all the patients, the time of operation being in every instance within the first month of life. A laparotomy was performed and, once the contralateral kidney had been carefully examined, a nephroureterectomy was implemented, having been able to preserve in all the cases the suprarenal gland in view of the benign nature of the tumor. A histologic study confirmed the diagnosis and revealed the complete delimitation of the tumor by the renal capsule. The authors underscore the importance of this tumor's suspicion in the face of any solid renal mass detected by prenatal echography or in the neonatal period, since early diagnosis and treatment are imperative in order to prevent the ensuing complications in the rare and unfortunate cases that show a malignant tumoral trend.

[Intestinal diversions in the treatment of Hirschsprung's disease].

Forty six enterostomies performed among one hundred and thirty one patients with Hirschsprung's diseases are reviewed. The advantages and disadvantages of the different types of intestinal diversions are considered. We conclude that the best option is to make a terminal enterostomy just proximal to the aganglionic gut.

[First infantile liver transplants in Spain].

For the first time in Spain, authors report the experience, started by the Hospital Infantil "Valle de Hebron" of Barcelona on pediatric liver transplant in terminal liver disease in childhood which means a new opportunity for these patients otherwise facing a fatal out come in a short time. We show the 4 first pediatric liver transplants performed in our country and we point out some of the most important factors of a pediatric liver transplant program in a consolidation phase.

[Surgical treatment of pneumothorax in the newborn infant].

Tension pneumothorax refractory to thoracocentesis is a serious consequence of the greater refinements of neonatal intensive care. Various techniques have been recently proposed for solving this problem, such as selective intubation or surgical treatment. We present our experience with the surgical treatment of refractory pneumothorax compared to conservative methods. In the 3 operated cases a notable improvement of ventilatory conditions was observed without the need of posterior drainage.

[Gastric chemistry in the pathology of the cardiohiatal sector].

Study of gastric chemistry in patients with cardiohiatal anomalies is an efficient test for distinguishing those cases that can evolution with complications and thus require surgical intervention. From a total of 720 patients affected with this pathology and observed between 1976 and 1982, a group of 164 were submitted to this study, 72 resulted with gastric acid rates higher than normal. 55% of these patients were operated. It is an easy test to realize in any service of Pediatric Surgery.

[Clinical value of intraesophageal pH measurement in children. Experience in 235 cases].

The intra-esophageal pH test is presented as a diagnostic method and as a control of GER, considering the 24-hour test as the best among all exploratory methods. The authors present 235 studied cases, distributed as follows: a control group of 20 normals, 24 cases explored after surgery, 80 cases of children with recently diagnoses GER or cases of bad response to postural treatment and 111 cases at the end of a favourable postural treatment. The normal quantitative values of 24-hour esophageal monitoring by pH-metry are presented in children and these are compared between the aforementioned groups. A detailed study of these explorations allows the authors to make a quantitative value of GER and to find out which ones of the studied parameters are more reliable for diagnosis (percentage of time under pH less than 4), and which ones indicate the severity of the process (refluxes of more than five minutes) that condition a change of treatment for the patient. Likewise, this study also permits the establishment of a relationship between GER and respiratory symptoms.
