ABSTRACT
Objetivo. Analizar ventajas y desventajas de la técnica de Seldinger (TS) frente a la disección abierta (DA) en la implantación de reservorios intravenosos (RIVS), comparando tiempos quirúrgicos y complicaciones. Material y Método. Realizamos un estudio analítico retrospectivo tipo cohortes históricas, comparando nuestra experiencia en la implantación de RIVS por DA y por TS. Analizamos parámetros clínicos, quirúrgicos, destacando el tiempo operatorio y las complicaciones intra/postoperatorias. Resultados. Analizamos 193 RIVS (119 DA, 74 TS) implantados principalmente para quimioterapia (83,41%). El tiempo quirúrgico utilizado en procedimientos únicos fue de 72,85 ± 29,35 minutos para DA frente a 62,83 ± 20,08 minutos el Seldinger (p<0,05). No hubo diferencias operador-dependientes. No se encontraron diferencias estadísticamente significativas entre las poblaciones de las dos cohortes estudiadas ni en el porcentaje de complicaciones. Los RIVS de mayor tamaño presentaron una media mayor de necrosis de piel (p>0,05) en cambio, los de menor tamaño presentaron mayor tasa de infección (16%sobre 7,7% p>0,05). Tanto en la TS (51,67 vs 98,14 min) como en la DA (78,56 vs 123,61 min) el tiempo operatorio fue menor en los accesos venosos izquierdos. (d =171 vs i =19) Tras complicaciones se retiró el RIVS en 121 días de media. Conclusiones. La TS disminuyó la perdida definitiva de los accesos venosos intervenidos, pudiendo reutilizar la misma vena para la colocación de RIVS posteriores. La TS reduce el tiempo quirúrgico, sin incrementarse las complicaciones. El acceso venoso izquierdo no implica mayor tiempo quirúrgico. Las complicaciones podrían estar en relación al tamaño del RIVS (AU)
Objective. To analyze advantages and disadvantages between Seldingers technique (ST) and surgical dissection (SD) on intravenous sport-a-caths comparing surgical parameters as time and complications. Material and Method. An analytic retrospective study involving historic cohorts was realized, comparing our surgical experience on port-a-cath implantation with Seldinger technique or surgical dissection. Statistical analysis was made reflecting clinical and surgical parameters, such as surgical time length and intra/postoperative complications. Results. 193 Port-a-caths were analyzed (119 SD, 74 ST), mainly placed for chemotherapy treatment (83.41%). Surgical time length expended at single procedures was 72.85 ± 29.35 minutes for SD and62.83 ± 20.08 minutes for ST (p<0.05). There were none operator dependent differences. Statistically significant differences were not found between the two cohorts populations, neither at complications percentages. Greater-sized port-a-caths presented a higher average of skin necrosis (p>0.05) however, lower-sized port-a-caths showed a high eraverage of infection (16% upon 7.7% p>0.05). Both ST (51.67 vs.98.14 min) and SD (78.56 vs. 123.61 min) showed lower surgical time length at left venous accesses (d =171 vs. i =19). Average in days for the extraction of port-a-caths with regard to complications was 121 days. Conclusion: Seldinger technique reduced the definitive lost of surgical dissected venous accesses, being possible further utilization of the same vein for subsequent port-a-caths. Seldinger technique reduces surgical time length without increasing complications rate. Left venous access does not imply higher surgical time length. Complications maybe related with port-a-caths size (AU)

Between November 1978 and July 1991, ten children between one and eight years of age with Group III pelvic rhabdomyosarcoma (IRS classification) and considered inoperable at diagnosis were treated primarily with intensive poly-chemotherapy. Complementary radiotherapy and conservative surgery were added as needed. Eight of the ten survive free of disease with functioning bladders for periods ranging from 5.7-18.4 years.

In 4 of 35 childhood Wilms' tumors on record in the Hospital Infantil Virgen de Rocio de Sevilla, it was possible to identify diffuse anaplasia despite the fact these children had received cytoreductive chemotherapy preoperatively.

A 3-year-old girl with Wilms' tumor developed pulmonary metastases 5 months after diagnosis. All but one of the visible lesions disappeared after thoracic irradiation and multiple-agent chemotherapy. Subsequent thoracotomy revealed 17 small nodules in addition to the visible lesion, and all of them proved to be fibromas. It would appear that the Wilms' tumor metastases to the lung were made to mature to benign neoplastic processes after the treatments given.

Authors present two cases of rhabdomyosarcoma of the bladder treated previously to surgery with chemotherapy (protocol T-2) and radiation therapy. In one of these patients surgery consisted only in a partial cystectomy, and in the other only a few biopsies were taken from the most suspicious zones, and these were all negative. Three years and four months after diagnosis and 15 months after completion of treatment, both children are alive and free of detectable disease.

Three cases of the rare malformation pyloric atresia are presented, two of which are associated with epidermolysis bullosa, a rare malformation by itself. First two cases had a great pneumoperitoneum which suggested perforation of digestive tract. All three cases belonged to type I of pyloric atresia.
