Explican en "Epidemiology" que bastantes estudios han relacionado la apendicectomía con el menor riesgo de esta enfermedad inflamatoria intestinal, si bien la causa de ello no está clara.
En su estudio analizaron datos de unos 230.000 individuos operados de apendicitis entre 1997 y 1999. En este grupo, la tasa de incidencia de la colitis ulcerosa fue de 17,6 por 100.000 personas al año antes de la cirugía y de 13 por 100.000 tras la intervención. Basándose en datos de la enfermedad en la población danesa, los investigadores señalan que los casos esperados en el grupo de estudio hubieran sido 496 tras haber sido sometidos a apendicectomía; sin embargo, el número de casos real fue sólo de 330.
