title: Effect of the herbal medicine Dai-kenchu-to for serum ammonia in hepatectomized patients.
abstract: OBJECTIVE
  Prolonged paralytic ileus occurring in hepatectomized patients may induce hyperammonemia or bacterial translocation, which injures the remnant liver function and sometimes causes post-resection liver failure. We examined the effectiveness of the herbal medicine, Dai-kenchu-to (DKT), on postoperative serum ammonia levels in patients with liver resection and compared it with lactulose.
  
  
  METHODS
  Patients with liver resection were divided into three groups. Lactulose group (n=31), 16g of lactulose was administered orally three times a day from the first postoperative day. DKT group (n=27), 5g of DKT was administered in the same fashion. Control group (n=26), neither lactulose nor DKT was administered. In all three groups, 16g of lactulose was administered three times a day for three days preoperatively.
  
  
  RESULTS
  There was no significant difference among the groups in age, gender and preoperative hepatic functional values, such as ICG-R15 or galactose tolerance test. There was also no difference in parenchymal hepatic resection rate, operative time and amount of intraoperative bleeding volume. Postoperative serum ammonia levels were significantly lower in the DKT group than control and lactulose groups. Instances of delayed flatulence and occurrence of diarrhea were also fewer in the DKT group.
  
  
  CONCLUSIONS
  DKT may become a more effective and safe agent than lactulose in postoperative management of liver resection.
