This multicenter, randomized, double-blinded, placebo-controlled study will evaluate the effect of TU-100 on resolution of postoperative ileus (POI) in subjects undergoing open or laparoscopic bowel resection (BR).

TU-100 is a gastrointestinal drug produced from the three botanical raw materials, Asian ginseng, Zanthoxylum fruit (Japanese pepper), and ginger, based on proprietary aqueous decoction and granulation technology. The aim of this study is to assess the effect of TU-100 on post-operative quality of life during the 4 week postoperative period after straight, hand-assisted, or robot-assisted laparoscopic colectomy. Optimal efficacy parameters for subsequent outcome studies also will be explored.

The aim of this study is to assess the effect of orally administered TU-100 (5 g three times daily [TID]) as compared to placebo on abdominal bloating rating in female IBS patients.
