Abstract

Background We assessed the efficacy of TJ-100 taken perioperatively to recovery among patients with periampullary tumor or tumor of the head of the pancreas who underwent pancreaticoduodenectomy (PD). Patients and methods In this multicenter, randomized, double-blinded, placebo-controlled, phase II trial (Japan-PD Study), patients were assigned randomly in a 1:1 ratio to receive TJ-100 or placebo. The coprimary endpoints were (1) incidence of postoperative paralytic ileus lasting >72 hours after surgery and (2) time to occurrence of postoperative paralytic ileus. This trial is registered at the UMIN Clinical Trials Registry (000007975) and at ClinicalTrials.gov (NCT01607307). Results From August 2012 through July 2013, we assessed 273 patients for eligibility, and 224 underwent randomization; 112 patients received TJ-100, and 112 patients received placebo. The population for analysis consisted of 104 patients who received TJ-100 and 103 who received placebo. Paralytic ileus occurred 35 (33.7%) in the TJ-100 group and 38 (36.9%) in the placebo group (P =.626). Time to first flatus was 2.25 (2.00-2.50) days in the TJ-100 group and 2.50 (1.50-2.50) days in the placebo group (P =.343). Among 23 patients who underwent a pylorus ring-preserving PD, time to first flatus was lower in the TJ-100 group than in the placebo group: 0.50 (0.50-1.00) days versus 1.50 (0.50-3.00) days (P =.034). Conclusion Our findings suggest that use of TJ-100 did not improve recovery from paralytic ileus after PD, and may preclude the routine use of TJ-100 in clinical practice after PD operation.
