Resultados. En nuestra serie, las enfermedades previas del paciente no influyeron en la evolución de la enfermedad. Hemos encontrado una incidencia de pancreatitis aguda de origen desconocido (11,2%) inferior a la de la mayoría de series reflejadas en la bibliografía, no asociándose este grupo a un peor comportamiento evolutivo. La mortalidad de esta serie fue muy baja, con tan sólo 2 casos (1,6%). Las escalas de Ranson y fallo orgánico sistémico no permitieron estratificar a los pacientes en la predicción de la gravedad evolutiva de la pancreatitis aguda.
Conclusiones. La pancreatitis aguda en el anciano es, en nuestra experiencia, una entidad con baja mortalidad. En nuestra serie las causas de este hecho han sido la baja incidencia de fallo orgánico, la mayor incidencia de pancreatitis de origen conocido y la ausencia de pancreatitis aguda postoperatorias. En nuestra opinión, el cirujano no debe basar el pronóstico del paciente ni en la presencia de enfermedades concomitantes ni en los valores de las escalas Ranson y fallo orgánico sistémico
Patients and methods. A series of 125 patients aged 75 years or more, treated in our center for acute pancreatitis between 1989 and 1994, was studied retrospectively. There were 35 men (28%) and 90 women (72%). The mean age was 81 years (range: 75 to 98 years). The data collected for the study consisted of: previous diseases, duration of symptoms (hours), Ranson score, MOF score at admission, etiology of the pancreatitis, treatment, morbidity, mortality and length of hospital stay (days). All the findings were analyzed statistically.
Results. In our series, previous diseases had no impact on the course of acute pancreatitis. We observed a lower incidence of acute pancreatitis of unknown origin (11.2%) than that reported in most of the series in the literature. This suggests that this patient population is not associated with a poorer outcome. The mortality in our series was very low, with only two deaths (1.6%). The Ranson and MOF scores did not permit severity stratification and outcome prediction for acute pancreatitis.
Conclusions.. In our experience, acute pancreatitis in the elderly is associated with a low mortality rate. The reasons for this finding in our series were the low incidence of organ failure, the higher incidence of pancreatitis of known origin and the absence of postoperative acute pancreatitis. In our opinion, the surgeon should not base patient prognosis on the presence of concomitant disease or on the Ranson or MOF scores
