title: [Use of preoperative glucocorticoid to reduce risk of complications after esophagectomy for carcinoma of the esophagus: meta-analysis].
abstract: OBJECTIVE
  Preoperative glucocorticoid administration has been proposed to reduce postoperative morbidity. This is not frequently done before esophageal resection because of insufficient knowledge on its effectiveness. The purpose was to assess the effects of preoperative glucocorticoid administration in adults undergoing esophageal resection for esophageal carcinoma.
  
  
  METHODS
  Studies were identified by searching the Cochrane Controlled Trials Register, Medline, Embase, Scielo and Cochrane Library, and by a manual search for relevant articles. In this systematic review, the last search for clinical trials was performed in December 2005. This review included randomized studies of patients with potentially resectable carcinomas of the esophagus that compared preoperative glucocorticoid administration with placebo. Data were collected by the reviewer, and quality of the trial was assessed using Jadad scoring. Odds ratio with 95% confidence intervals was used to assess the significance of the difference between treatment arms.
  
  
  RESULTS
  Four randomized trials involving 169 patients were found. There were no differences in postoperative mortality, anastomotic leakage, hepatic and renal failure between the glucocorticoid and placebo groups. There were fewer postoperative respiratory complications (95% CI= 0.09-0.46), sepsis (95% CI= 0.10-0.81), and total postoperative complications (95% CI=0.06-0.23) with preoperative glucocorticoid administration.
  
  
  CONCLUSIONS
  Prophylactic administration of glucocorticoids is associated with decreased postoperative complications.
