abstractinverse relationship between intervention volume and complications of esophagectomy and pancreatectomy. a review background: The prevalence of pancreatic cancer increased in Chile in the last decade, while that of esophageal cancer is decreasing. Both diseases are a surgical challenge due to their high mortality and rate of complications. aim: To analyze the relationship between intervention volume and surgical complications. material and methods: We reviewed 19 papers analyzing the relationship between the number of interventions performed in a determinate hospital (yearly hospital volume), the number of interventions performed by each surgeon (yearly surgical volume) and the rates of mortality and complications of both conditions. results: There is a clear inverse relationship between volumes and complications. There is also a higher five years survival in high volume hospitals. conclusions: Intervention volume is inversely associated with rates of complications.

Bursectomy and omentectomy in the surgical treatment of gastric cancerThere is controversy about the usefulness of bursectomy and omentectomy during the surgical treatment of gastric cancer. Bursectomy, a procedure dissecting the peritoneal lining covering the pancreas and the anterior plane of the transverse mesocolon, is a major surgical aggression. There is no evidence that the procedure improves five years survival. It may be useful in serosal gastric cancer of the posterior wall. Excision or resection of all or part of an omentum does not have either an effect on survival. However, we recommend its use since its lack of benefit has not been completely ascertained.Dentro de las etapas quirúrgicas de la gastrectomía por cáncer gástrico, existen controversias respecto a la bursectomía y la omentectomía. La bursectomía (resección de peritoneo que cubre la porción anterior del mesocolon transverso y la cápsula pancreática) representa una mayor agresión quirúrgica, sin evidencia actual de que aumenta la sobrevida a 5 años, ello evaluado en 3 estudios clínicos. Su utilidad parece estar en pacientes con cáncer gástrico seroso de la cara posterior. La omentectomía total, comparada con la omentectomía parcial, ha sido evaluada más extensamente, sin poder demostrar hasta la actualidad la superioridad de uno u otro procedimiento en cuanto a sobrevida a 5 años. Sin embargo, mientras no se demuestre claramente lo opuesto en estudios científicos, recomendamos realizarla rutinariamente.Palabras clave: Cáncer gástrico, omentectomía, bursectomía.
