By combining colonoscopic findings with other diagnostic tools and the clinical history the present study has been able to determine the most frequent causes of colitis in approximately 80% of the patients studied. 12% of the patients had "other" causes and 10 patients probably had infectious colitis, although we can reasonably assume that four of these were the result of C. difficile and that 40% of the probably infectious colitis cases were pseudomembranous colitis.
En el presente estudio, combinando el cuadro clínico, los hallazgos endoscópicos y la historia clínica, se pudieron determinar las causas más frecuentes en aproximadamente el 80% de los pacientes por cuanto las causas fueron "otras" en el 12% y de los 10 pacientes con probables causas infecciosas hubo seguridad razonable de que fuera por C. difficile en 4, así, el 40% de las infecciosas tenía seudomembranas.
