title: [Effect of Preoperative Bowel Preparation on Surgical Site Infection in Liver Surgery].
abstract: BACKGROUND
  In our institute, the protocol for preoperative bowel preparation before liver surgery has been changed from polyethylene glycol lavage (NiflecR: N group) to magnesium citrate (MagcorolR: M group).
  
  
  METHODS
  Ninety patients who underwent hepatectomy without reconstruction of the bile duct, gastorectomy, or colorectal resection from 2012 to 2013 were enrolled in this study. The impacts of preoperative bowel preparation were compared between the 2 groups.
  
  
  RESULTS
  There were no significant differences between the 2 groups in terms of surgical procedure, operative time, bleeding amount, and duration of postoperative hospital stay. Surgical-site infection did not occur in both groups. There were no significant differences in the white blood cell count and platelet count of the patients in both groups. The C-reactive protein level in the M group was significantly lower than that in the N group on days 1, 3, and 5 after the operation, whereas the ammonia level in the M group was significantly lower than that in the N group on day 5 after the operation.
  
  
  CONCLUSIONS
  It is possible to simplify preoperative bowel preparation associated with liver surgery while ensuring appropriate safety.
