ABSTRACT

Objective:To determine whether chewing gum during the postoperative period facilitates the recovery of bowel function in patients after radical cystectomy with ileum urinary diversion.Methods:In the study,60 patients who underwent radical cystectomy followed by ileum urinary diversions during Nov.2014 and Nov.2015 in Department of Urology of Peking University First Hospital were randomized into three groupsgum chewing group,placebo group treated with the abdomen physical therapy machine and control group treated with ordinary method.Time to flatus,time to bowel movement,incidence of postoperative distension of the abdomen and abdominal pain,and gut related complications (such as ileus,intestinal fistula,and volrulus)of all the patients were recorded and analysed.Results:In gum chewing group,the median time to flatus was 57 hours (49 -72 hours),and the median time to bowel movement was 95 hours (88 -109 hours),which were significantly shortened compared with the other two groups of patients (82 hours,109 hours in placebo group and 81 hours,108 hours in control group, respectively).No significant difference of the median time to flatus and to bowel movement was observed between placebo group and control group.There were no significant differences in the incidence of post-operative distension of the abdomen and abdominal pain,and gut related complications among the three groups.Conclusion:Chewing gum had stimulatory effect on bowel function recovery after cystectomy fol-lowed by ileum urinary diversion.Chewing gum was safe and simple,and could be routinely used for postoperative treatment after cystectomy and ileum urinary diversion.
