    Beschreibung / Inhaltsverzeichnis: Résumé La maladie de Hirschprung est rare (une sur 5000 naissances), atteint surtout les garçons, mais constitue une cause fréquente d'occlusion chez le nouveau-né. Elle se caractérise par l'absence de cellules ganglionnaires dans l'intestin distal d'extension proximale variable. Dans 75% des cas, elle n'intéresse que le rectum et colon sigmoïde. Le diagnostic repose sur la clinique, les données de la manométrie anorectale et surtout l'examen anatompathologique, qui seul confirme la zone aganglionnaire. Le traitement est une reconstruction colorectale, soit traditionnellement en deux-temps, soit, de plus en plus souvent, en un seul temps opératoire. L'association d'une entérocolite est une complication grave et nécessite, en urgence, une réanimation adaptée et souvent une colostomie.
    Kurzfassung: Resumen La enfermedad de Hirschsprung es una causa relativamente común de obstrucción intestinal en el recién nacido. Se caracteriza por ausencia de las células ganglionares en el colon distal a partir del esfínter interno hasta distancias variables en sentido proximal. La aganglionosis aparece confinada al rectosigmoide en 75% de los pacientes, al sigmoide, ángulo esplénico o colon transverso en 17%, y a la totalidad del colon con un corto segmento del ileon en 8% de los pacientes. La aganglionosis intestinal total con ausencia de células ganglionares desde el duodeno hasta el recto constituye la forma más rara dse enfermedad de Hirschsprung. Se estima la incidencia de la enfermedad de Hirschsprung en 1 en 1.500 nacimientos vivos. Spouge y Baird estudiaron la incidencia en la prpovincia de British Columbia y reportan una tasa de 1 en 4.417. La entidad es más común en los niños, con una relación masculino: femenino de 4∶1, pero esta mayor prevalencia en el sexo masculino es menos evidente en los pacientes con largos segmentos afectados, donde la relación de sexos es 1.5∶2.1. En este artículo se revisa la etiología, patofisiología, patología, cuadros clínicos, métodos de diagnóstico y manejo. La enterocolitis se mantiene como la complicación más grave de la enfermedad de Hirschsprung y se asocia con alta morbilidad y mortalidad.
    Notizen: Abstract Hirschsprung's disease (HD) is a relatively common cause of intestinal obstruction in the newborn. It is characterized by an absence of ganglion cells in the distal bowel beginning at the internal sphincter and extending proximally for varying distances. The etiology of HD-associated enterocolitis remains a complex issue. This study has provided further support for a possible infectious etiology of enterocolitis complicating HD.

    Notizen: Abstract Appendicitis in preschool children, although uncommon, is associated with a high perforation rate and increased morbidity. Of 132 preschool children treated for appendicitis over a 5-year period, 63 (47.7%) had perforations and 29 (22.0%) had an appendiceal mass. Although classic symptoms were present in the majority of the patients, atypical symptoms were found in many children and included diarrhoea (35), cough/sore throat (15), dysuria (4), headache (2), and earache (2). A diagnosis other than appendicitis was suspected by attending medical practitioners in 53 (40%) patients, leading to delay in management. Mean duration of symptoms before admission was as follows: acute appendicitis 38.9 h, perforation 52.6 h, and appendix mass 81.7 h. Ten (7.6%) patients developed postoperative complications that included wound infection in 5, intra-abdominal abscess in 4, and adhesive intestinal obstruction in 1. A high index of suspicion of appendicitis is necessary in preschool children in view of the atypical presentation and high incidence of advanced appendicitis and morbidity.

    Notizen: Abstract The pathophysiology of Hirschsprung's disease is not fully understood. Using light microscopy we have previously demonstrated the absence of a unique Schwann-cell antigen in the circular muscle of aganglionic colon identified by D7 monoclonal antibody. In an attempt to characterise the morphological changes in neuronal cells at subcellular level, we studied innervation patterns in normal and aganglionic colon by electron microscopy. The most striking observation on ultrastructural serial examination of the entire resected specimen of colon from patients with Hirschsprung's disease was the presence of grossly swollen monoaxonal or oligoaxonal Schwann cell units with loss of cellular contents in the circular muscle of aganglionic colon. The extent of subcellular changes in Schwann cells and axons corresponded with a diminution of immunoreactivity with a panel of neuronal cell antibodies. These ultrastructural findings suggest that degenerative changes in Schwann cells and axons within the circular muscle coat of aganglionic segment may be a significant factor in the pathogenesis of Hirschsprung's disease.

    Thema: Medizin
    Notizen: Abstract The internal anal sphincter is morphologically derived from the circular muscle of the rectum, but marked differences have been observed in the motor activities of these two morphologically continuous structures. Immunocytochemical studies using anti-neurotransmitter antibodies (vasoactive intestinal peptide, substance P, metenkephalin, neuropeptide Y), enzyme histochemistry for acetylcholinesterase, and electron microscopy were carried out on internal sphincter specimens from 14 patients with internal sphincter achalasia, 5 normal controls, and on rectum from 4 patients with Hirschsprung's disease (HD). The various peptide-containing nerves were increased in internal sphincter achalasia compared to normal controls and patients with HD. The pathophysiology of internal sphincter achalasia appears to differ from that of HD. It is a distinct clinical entity and should be considered separate from the latter.

    Notizen: Abstract The case of a premature infant with a simultaneous occurrence of appendiceal perforation and incomplete fixation of the colon producing early obstruction of the duodenum is reported. The clinical examination and laboratory and radiological investigations were all negative for the diagnosis of appendicitis, which was found incidentally at laparotomy for duodenal obstruction.

    Thema: Medizin
    Notizen: Abstract Levatorplasty has been used successfully in children with secondary faecal incontinence. A posterior sagittal approach in anorectal anomalies gives excellent delineation of the anatomy of the pelvic floor and perineum. Between August 1985 and December 1989, 13 children underwent levatorplasty using a posterior sagittal approach for faecal incontinence following primary operations for imperforate anus. There were 9 boys and 4 girls; 7 of them had a major associated anomaly. Twelve patients had a high anorectal anomaly and the primary operation was a sacro-perineal or sacro-abdomino-perineal pull-through. One had an intermediate anomaly treated by a perineal operation. All patients had persistent soiling and among them had 27 further unsuccessful operations to improve continence prior to posterior sagittal levatorplasty. Six patients had good and 7 had poor to moderate voluntary squeeze pressures prior to levatorplasty. Age at posterior sagittal levatorplasty ranged from 4 to 17 years (mean 10.7 years). All patients were followed up for periods ranging from 2 years 2 months to 6 years 5 months (mean 4.7 years). At least review 6 patients (46%) had excellent results with full continence and no soiling; 5 (39%) showed significant improvement compared with the pre-operative state with occasional soiling only. Of these, 3 patients opted for total colonic irrigation once a day to remain clean at all times. Two patients (15%) had poor results with frequent soiling. The posterior sagittal approach provides excellent exposure for levatorplasty. Best results were obtained in patients who had good voluntary squeeze pressures on anorectal manometry prior to the operation.

    Thema: Medizin
    Notizen: Abstract A newborn who was operated upon for a benign sacrococcygeal teratoma at the age of 2 weeks developed haemodynamic instability with a shock episode at the time of operation. The serum level of tumour necrosis factor alpha (TNF-Alpha) during this event rose to 158 pg/ml (normal 〈15 pg/ml). Preoperatively TNF-Alpha was undetectable, while post-operatively the level was 23 pg/ml. Serum levels of the cytokine interleukin-1 beta (IL-1 beta) were undetectable throughout the study. The baby was treated successfully by fluid challenge and dopamine. This case represents a temporal association between haemodynamic instability during surgical intervention and a high serum level of TNF-Alpha, which is an important mediator in the pathogenesis of septic shock.

    Thema: Medizin
    Notizen: Abstract Mucosal defence mechanisms of the excluded bowel were studied in 12 patients with Hirschsprung's disease. The entire resected segment of colon obtained following Swenson's operation was cut at 0.5-cm intervals and serially examined by routine haematoxylin and eosin staining, immunocytochemistry, and mucin histochemistry. Seven patients who had clinical evidence of enterocolitis prior to defunctioning colostomy showed histological and immunological evidence of enterocolitis (crypt abscesses, ulceration, leucocyte aggregation, Paneth cell metaplasia, and marked immunocyte responses) in the excluded bowel even several months after diversion of the faecal stream. Mucin histochemistry showed marked depletion of neutral mucins and sulphomucins in the excluded bowel with inflammatory changes and reversal of the sialo- to sulphomucin ratio. These results indicate that patients with enterocolitis complicating Hirschsprung's disease have persistent inflammatory changes in the excluded large bowel after diversion of the faecal stream by colostomy. Environmental factors such as bacterial stimulation and proliferation probably cause inhibition of cell renewal, resulting in abnormalities of mucin fractions. Changes in mucin composition, which is an important mechanical and chemical factor of the mucosal defence mechanism, may lead to altered susceptibility to bacterial degradation and hence may be important in the pathogenesis of enterocolitis.
