Abstract

Objective: This exploratory trial was performed to determine whether Daikenchuto accelerates recovery of gastrointestinal function in patients undergoing open colectomy for colon cancer. Methods: A total of 386 patients undergoing colectomy at 1 of the 51 clinical trial sites in Japan from January 2009 to June 2011 were registered for the study (JFMC39-0902). Patients received either placebo or Daikenchuto (15.0 g/day, t.i.d) between post-operative day 2 and post-operative day 8. Primary end-points included time to first bowel movement, frequency of bowel movement and stool form. The incidence of intestinal obstruction was evaluated post-operatively. The safety profile of Daikenchuto until post-operative day 8 was also evaluated. Results: The results for 336 patients (Daikenchuto, n = 174; placebo, n = 162) were available for statistical analysis. The time to first bowel movement did not differ significantly between the two groups. All patients reported having diarrhea or soft stools immediately after surgery, and the time until stool normalization (50th percentile) in the Daikenchuto and placebo groups was 6 days and 7 days, respectively. The placebo group had a significantly greater number of hard stools at post-operative day 8 (P = 0.016), and bowel movement frequency continued to increase until post-operative day 8 aswell. In contrast, bowelmovement frequency in theDaikenchuto group increased until post-operative day 6, however decreased frompost-operative day 7 andwas significantly lower at post-operative day 8 compared with the placebo group (P = 0.024). Conclusion: The moderate effects of Daikenchuto were observed ~1 week after the operation. Although Daikenchuto had an effect on gastrointestinal function after open surgery in patients with colon cancer, this study did not show its clinical benefits adequately.
