title: [Usefulness of chewing gum for the resolution of postoperative ileus in left colon resections].
abstract: OBJECTIVE
  Disturbances in intestinal motility have been described since XIX century, with a not very well understood pathogenesis and few therapeutic approaches. Considering chewing as an important stimulus to promote intestinal motility we designed this study to assess the efficacy of chewing gum to improve the postoperative ileus, and the clinical relevance of this intervention.
  
  
  METHODS
  Were included patients who underwent for elective left hemicolectomy during January 2007 to December 2008. The patients were randomly assigned to receive chewing gum or nothing during the post-surgery period. The main outcomes assessed were duration of postoperative ileus, and reduction in hospitalization days.
  
  
  RESULTS
  During the period of the study were included 32 patients, were included mainly men (11 and 9 in treated and control patients, respectively). The first defecation after surgery procedure occurs at (44.2 ± 17.6 h) in the treated group and (55.5 ± 14.8 h) in the control group (p = 0.05). In the same way oral tolerance was achieved faster in the treated group (p= 0.05). The hospital stay duration was not different among treated and not treated patients.
  
  
  CONCLUSIONS
  The use of chewing gum in patients after elective left hemicolectomy, reduce the duration of the postoperative ileus. However, this does not reduce the hospital stay duration.
