About

A multicenter randomized-controlled trial of daikenchuto (TJ-100), a traditional Japanese herbal medicine (Kampo), to investigate its effect on intestinal dysmotility and for the prevention of postoperative paralytic ileus.

Full description

Daikenchuto (TJ-100), a traditional Japanese herbal medicine, is used for prevention and treatment of postoperative ileus. TJ-100 extract powder (Tsumura & Co., Tokyo, Japan) is manufactured as an aqueous extract containing 2.2 % Japanese pepper, 5.6 % processed ginger, 3.3 % ginseng, and 88.9 % maltose syrup powder. A recent randomized, parallel-group, double-blind, placebo-controlled, dose-response trial demonstrated that TJ-100 accelerates colonic transit time, particularly in the ascending colon. Given its potential actions in the intestinal tract, it seems reasonable to postulate that TJ-100 may play a role in improving and preventing bowel dysmotility. This study was designed to investigate the effect of TJ-100 on intestinal dysmotility and for the prevention of postoperative paralytic ileus in patients undergoing pancreaticoduodenectomy.

The primary endpoint is the incidence of postoperative paralytic ileus. Secondary endpoints are QOL assessment by the Gastrointestinal Symptom Rating Scale (GSRS) Score (Japanese Version) and visual analogue scale, the change in ratio of abdominal circumference, the incidence of postoperative complications, the length of hospital day, and the incidence of surgical site infection. Two hundred patients are required for the study (100 patients per group).
