Perioperative administration of Daikenchuto (TJ-100) reduces the postoperative paralytic ileus in patients with pancreaticoduodenectomy.

Abstract

Background/aims: No study has reported whether perioperative administration of Daikenchuto (TJ-100) reduced paralytic ileus after pancreaticoduodenectomy (PD).

Methodology: Forty-five consecutive patients that were scheduled to undergo PD at Wakayama Medical University Hospital between August 2010 and August 2011 were enrolled in this study including the first cohort (n = 15) as the control group and the subsequent cohort (n = 30) as the TJ-100 group. This trial was registered at UMIN-CTR ID# 000005056.

Results: Postoperative paralytic ileus occurred more frequently in the control group (73.3% of the control group and 20.0% of the TJ-100 group; p = 0.001). The first passages of flatus significantly improved earlier in the TJ-100 group than in the control group (p = 0.014). A multiple cytokine assay of the drainage and serum showed that IL-9 and IL-10 in the drainage was significantly higher on postoperative day 1 in the TJ-100 group. There were no complications associated with the preoperative administration of TJ-100 before surgery, and no significant differences were observed between the two groups in the incidence of postoperative Gradel-2 diarrhea (CTCAE4.0).

Conclusions: Perioperative administration of TJ-100 was feasible and reduced the incidence of paralytic ileus in PD, and further randomized controlled trials should be conducted.
