title: [Splenectomy indications at a general hospital].
abstract: BACKGROUND
  To analyse the evolution of indications for splenectomy for a 11-year period.
  
  
  METHODS
  A review was made of cases of splenectomy from clinical records and the records of the Pathology Service at Hospital General Universitario Gregorio Marañón from 1986 to 1996. Both adult and pediatric cases were included.
  
  
  RESULTS
  From 1986 to 1996 there was a total of 354 patients (273 males and 162 females) who underwent splenectomy. Mean age of patients was 44.6 years (SD +/- 20.5 years) and there was an average of 39.5 cases per year. The most common causes were trauma (32%), "incidental" splenectomy (14%), thrombopenia (12%) and non Hodgkin lymphoma (11%). Compared with the other causes, the mean age of patients with trauma was lower than that of the other groups (p < 0.0001), in contrast with patients with non Hodgkin lymphoma or extra-splenic tumors, where it was higher (p < 0.0001 for both groups). A decline was observed of cases due to trauma from the first to the last year of the study (p = 0.0009), as well as an increase in the group of splenectomy related to extrasplenic tumors (p = 0.01). In the group of the HIV infected patients (n = 30), thrombopenia was the most common indication for splenectomy (11 cases).
  
  
  CONCLUSIONS
  Although the average of splenectomy cases remains relatively constant, a decrease in cases due to trauma was observed and an increase of splenectomies on account of abdominal oncologic resections.
