Objective  To compare the effect of three bowel preparation methods in radical cystectomy and ileal cystoplasty.

  Methods  A total of 46 patients scheduled for radical cystectomy and ileal conduit from March 2012 to November 2018 were selected as study objects, and were divided into group A from March 2012 to February 2016, traditional bowel preparation (TBP), group B from March 2016 to January 2018, rapid bowel preparation (RBP), and group C from February to November 2018, enteral nutrition (EN). The recovery time of intestinal function, intestinal cleanliness, tolerance and adverse reactions were compared among the three groups.

  Results  The recovery time of intestinal function in group C were significantly better than the other two groups(P < 0.05). No significant difference was found in intestinal clearance in three groups and postoperative complications between group A and group B(P>0.05).

  Conclusions  RBP method is safe and effective in preoperative bowel preparation for radical cystectomy and ileal conduit. EN method is as the same efficacy as the TBP and RBP in intestinal clearance, but is better in terms of time to flatus and bowel movement as well as tolerance than TBP and RBP, and can be recommended to as bowel preparationbefore radical cystectomy and ileal conduit.
