[Medical-surgical experience of intestinal intussusception. Experience of a university institution].

BACKGROUND: Management of intestinal intussusception in children has evolved from exclusively surgical treatments to nonoperative reduction under fluoroscopic monitoring. AIM: To report a 10 year experience in a University Hospital in the management of intestinal intussusception. PATIENTS AND METHODS: Seventy two patients, aged 2 to 72 months of age, with an uncomplicated intussusception, that were treated by barium or air enema, were studied. RESULTS: The success rate was 73% with barium reductions, and 100% with air reductions. In 17 patients (24%), enema reduction was unsuccessful and were subjected to a surgical reduction. CONCLUSIONS: Nonsurgical reduction is safe and effective as the initial treatment of uncomplicated intussusception in children.

[Hydrostatic reduction of intestinal intussusception in children. Experience in 43 cases].

BACKGROUND: Intestinal intussusception, a medical emergency, is more commonly idiopathic and ileocolic and occurs with higher frequency in children aged 6 months to 2 years. Barium enema confirms the diagnosis and allows its hydrostatic reduction, that is the treatment of choice of this condition. AIM: To report our experience with hydrostatic reduction of intestinal intussusception in children. PATIENTS AND METHODS: Hydrostatic reduction was attempted in 43 children with intestinal intussusception: 20 male, aged 2 to 48 months, that consulted at the Clinical Hospital of the Catholic University in Santiago. RESULTS: Hydrostatic reduction was successful in 33 children (77%) that were discharged from the hospital 24 to 96 hours after the procedure. A partial reduction was achieved in 10 patients (23%) who required surgery and were discharged from the hospital 5 to 8 days after the procedure. CONCLUSIONS: Our results are similar to those reported abroad and allow the recommendation of hydrostatic reduction as the treatment of choice for intestinal intussusception.

[Ultrasonography: the diagnostic method of choice in hypertrophic pyloric stenosis. Experience with 67 patients].

Hypertrophic pyloric stenosis (HPS) is a common medical emergency in newborns and lactating infants. Ultrasonography (US) is the diagnostic imaging procedure of choice in most centers, leaving the radiological study with barium for those cases in which US is negative and clinical symptoms persist or when other causes of vomiting must be discarded. We report our experience in 67 children (58 male) with suspected HPS. The US findings were consistent with HPS in 45 patients, and the diagnosis was surgically confirmed in all. In the remaining 22 patients with negative US findings, symptoms improved during follow up, with medical treatment. In one patient US was negative for HPS but showed an antral web, that was surgically confirmed. Since there were no false positive or negative results, the specificity and sensitivity of US for HPS diagnosis was 100%. We strongly recommend the use of US in patients with suspected HPS.

[Ultrasonographic diagnosis of hypertrophic pyloric stenosis].

Hypertrophic pyloric stenosis (HPS) is one of the most common causes of abdominal surgery during the first weeks of life. The primary cause of the muscular hypertrophy is unknown and the pathogenesis is obscure. Clinically, vomiting is always present and sometimes there is a palpable pyloric mass (olive). Upper gastrointestinal tract study with barium has been the most usual method for the diagnosis. Since the first report of the use of ultrasound (US) in the diagnosis of HPS in 1977, this technique has been widely used and accepted, being by now, the diagnostic imaging examination of choice for infants in whom this abnormality is suspected. This is our experience with the use of US in 27 infants with clinically suspected HPS. In 17 cases there was US evidence of HPS and in 10 patients results were negative. We did not have false positive neither false negative results. We strongly recommend this diagnostic method for all infants under clinical suspicion of HPS.

[Parenteral nutrition in critically ill newborns].

In nine critically ill newborns, five of them with intractable diarrhea and four surgical patients, we administered a 5% crystalline aminoacids solution (AA) and glucose in sufficient amount to provide 120 cal times kg. in 24 hours. Six of them recovered after receiving parenteral alimentation for 3 to 15 days, gained weight during or after treatment and were discharged from the hospital in good conditions. Three died, one of them presented septicemia and two pneumonia and pulmonary infarcts. The solution used generated few metabolic alterations, the acid-base status remained within normal range and there were not important changes in the sodium and potassium serum concentrations. On the contrary, children with hyponatremia and hypokalemia at the beginning of the treatment, normalized these constants within the first hours, as diarrhea ceased. The most frequent complications were infiltrations and reaction of the surrounding tissue of the catheterized vein and local skin infection. Only one patient died of septicemia, possibly caused by this proceeding. In summary, parenteral alimentation though not free from risk, seems to be a useful proceeding when oral feeding is impossible or inadvisable. The utmost danger is septicemia. Metabolic changes are minimal and they do not mean a risk for child's life; nevertheless, there is a need for long term studies to bring up definite conclusions. The solutions in actual use are probably not the most physiological for the newborn. It is necessary to adequate them according to the new advances made on child nourishment during his first days of life.

[Vascular rings].

22 cases of several types of vascular rings are presented. Most of them were double aortic arch (15): 12 were operated on without mortality before the first years of age because of the great severity of the symptoms. The precocity of the symptomatology and the predominance of the respiratory distress is emphasized. Our data point out to the importance of the differential diagnosis of vascular rings in newborns and infants in the presence of laryngeal stridor or respiratory distress, essentially because the surgical correction is very effective and the risk of the intervention is minimal.
