Medline, Pascal Biomed, Scisearch, EMBASE/Excerpta Medica, Lilacs, Medical Editors’ Trials Amnesty, and Centre for Reviews and Dissemination database (all from inception through March 2003); Cochrane Library (Issue 3, 2003); major surgical journals; conference proceedings; contact with experts; and bibliographies of relevant articles.
Study selection and assessment:
randomised controlled trials in any language that compared mechanical bowel preparation with no preparation before elective colorectal surgery. Studies were assessed for randomisation method, double blinding, and withdrawals or dropouts.
anastomotic leakage, wound infection, extra-abdominal septic complications, and non-septic complications.
7 studies (n = 1454; 720 patients had mechanical bowel preparation, and 734 had no preparation) met the selection criteria. 5 …
