title: [Enterocolitis episodes in patients who have previously undergone Hirschsprung disease surgery].
abstract: OBJECTIVE
  To highlight the risk factors for the occurrence of this complication in order to achieve an early diagnosis.
  
  
  METHODS
  Retrospective descriptive study in which the medical records of patients diagnosed with enterocolitis and who have previously undergone surgery for Hirschsprung's disease in a tertiary hospital from 1994 to 2013, inclusive (N=29), were reviewed. Epidemiological, surgical and clinical data from two groups of patients: Group A (6 patients with ECPD) and Group B (23 patients without ECPD) were compared. Enterocolitis episode data in the Group A were studied too.
  
  
  RESULTS
  The incidence of an episode of ECPD was 20.6% and the incidence of two episodes of ECPD was 33.3%. The onset occurred at 12.17 months (SD 13.04) after pull-through procedure. The incidence was higher in patients operated at a younger age [10 months in Group A [6-16] versus 14 months in the group B (1-153)] and in those patients with the longest segment resected [23.20 cm in group A (DS 10,52) versus 19.20 cm in group B (DS 6.92)]. No patient with a discharge colostomy before pull-through surgery showed this complication. It must be highlighted the highest incidence in patients undergone by Swenson's technique (25%) compared to other surgical techniques (Georgeson (15.80%), Soave (0%)).
  
  
  CONCLUSIONS
  Just the length of the resected segment and the patient's age at the time of the pull-through procedure appear to influence the outcome. It is considered advisable to be extremely vigilant in children operated at an early age and subjected to extensive intestinal resection for an early diagnosis and establishment of a treatment to avoid high morbidity.
