RESUMEN

BACKGROUND: The best results in the surgical treatment of gastric cancer are those obtained by the Japanese surgical school that emphasizes D2 lymphadenectomy as a fundamental principle for obtaining better local control of the disease. However, this technique has not gained wide acceptance in the West, owing to the fact that the results of Japanese studies have not been reproduced frequently in Western countries. In recent years, a series of studies have recommended the centralization of gastric cancer treatment in specialized surgical units in order to obtain results similar to those achieved by Japanese centers. The objective of this study was to describe the specialization process and to show the short-term results obtained in the surgical treatment of gastric cancer in the Specialized Unit of the Rebagliati National Hospital, the largest general referral hospital in Lima, Peru. METHODS: In the year 2000 a specialized service was created for the surgical treatment of gastric cancer, initiating a process that included the establishment of surgical treatment guidelines, training in the Japanese surgical technique, and progress along the learning curve for D2 lymphadenectomy. Clinical, surgical, and pathological data were recorded prospectively in a fixed format, considering that strict documentation of cases was also an important step within this process. RESULTS: Between January 1, 2004, and December 31, 2005, 243 consecutive patients with a proven diagnosis of gastric adenocarcinoma were admitted to the operating theater for surgical treatment. During this study period, morbidity was 22.7% and hospital mortality, 2.8%. The numbers (mean +/- SD) of resected lymph nodes for distal gastrectomy and total gastrectomy were 37.3 +/- 12.4 and 45.3 +/- 14.5, respectively. Hospital stay was 13 days for distal gastrectomy as well as for total gastrectomy. CONCLUSION: According to our results, adequate training in the Japanese surgical technique, progress along the learning curve for D2 lymphadenectomy, and the establishment of specialized units are highly recommended for the surgical treatment of gastric cancer in Western referral hospitals.

RESUMEN

This report describes the case of a patient who underwent total gastrectomy, splenectomy and pancreatomy corporo-postero as a consequence of gastric and pancreatic metastasis from carcinoma to clear cells, five years after having undergone radical nephrectomy. Upper digestive bleeding was the first symptom, and pancreatic lesion was detected in previous CT scans. There are many documented cases of pancreatic metastasis, but only eight gastric metastasis in the last 15 years, although we did not find reports about surgical treatment for concomitant gastric and pancreatic injury. Surgical treatment which in some reports include highly complex surgeries such as gastrectomies with combined resections of invaded organs and pancreatoduodenectomy, are good options for select cases, because good survival rates have been reported.

RESUMEN

El presente reporte se describe el caso de una paciente sometida a gastrectomía total, esplenectomía y pancreatectomía corporo-caudal por presentar metástasis gástrica y pancreática de carcinoma renal a células claras, 5 años después de haber sido sometida a nefrectomía radical. El cuadro se presentó como una hemorragia digestiva alta, y la lesión pancreática se evidenció en los estudios tomográficos previos a los que fue sometida la paciente. Existen muchos casos reportados en la literatura de metástasis pancreática, pero solo 8 en relación a metástasis gástrica. Sin embargo no encontramos reportado el tratamiento quirúrgico por lesión gástrica y pancreática concomitante. El tratamiento quirúrgico que en algunos reportes incluye cirugías de alta complejidad como gastrectomías con resecciones combinadas de otros órganos y pancreatoduodenectomía, se ofrecen como una buena alternativa para casos seleccionados ya que se han reportado buenas sobrevidas.

RESUMEN

The results of the surgical treatment for gastric cancer within a specialized surgical service in this pathology are described in this work. This system for surgical treatment of gastric cancer is new in our country. The implementation process included prepare a team of surgeons and establish protocols and guides to surgical treatment, based on the recommendations of the Japanese Gastric Cancer Association. Additional training in the Japanese advanced surgical technique was required, as well as a strict documentation of the cases. During 2004, 139 surgical interventions were carried out on 137 patients with tumoral gastric pathology. Surgical mortality was 2.1% and morbidity was 21.8%. The average resected glands was 38.6.t 13.7 (range: 20-87) for distal gastrectomy and 46.6 +/- 16.2 (range: 24-87) for total gastrectomy. The stay in the hospital was 11.7 +/- 6.3 days (range: 5-37) for distal gastrectomy and 14.8 +/- 11.3 days (range: 7-56) for total gastrectomy. The hospital and surgeon volumes are underlined as important factors in determining the short and long term results. Implementation of specialized surgical units in general hospitals, for surgical treatment of gastric cancer, is recommended.

RESUMEN

En el presente trabajo se describen los resultados del tratamiento quirúrgico del cáncer gástrico dentro de un servicio de cirugía especializado en ésta patología. Este sistema de trabajo para el tratamiento quirúrgico del cáncer gástrico es una experiencia nueva en nuestro país y su proceso de implementación incluyó la conformación del equipo de cirujanos, el establecimiento de protocolos y guías de tratamiento quirúrgico basados en las recomendaciones de la Asociación Japonesa de Cáncer Gástrico; el entrenamiento y perfeccionamiento en técnica quirúrgica japonesa y la documentación rigurosa de los casos. Durante el año 2004 se realizaron 139 intervenciones quirúrgicas en 137 pacientes con patología gástrica tumoral. La mortalidad quirúrgica fue de 2.1 por ciento y la morbilidad de 21.8 por ciento. La media de ganglios resecados fue de 38.6 + 13.7 (rango: 20-87) para gastrectomía distal y 46.6 + 16.2 (rango 24-87) para gastrectomía total. La estancia hospitalaria fue de 11.7 + 6.3 días (rango 5-37) para gastrectomía distal y 14.8 + 11.3 días (rango 7-56) para gastrectomía total. Se resalta el volumen hospital y volumen cirujano como importantes factores determinantes de los resultados a corto y largo plazo, recomendándose la implementación de unidades quirúrgicas especializadas en hospitales generales para el tratamiento quirúrgico del cáncer gástrico.
