Purpose: Recombinant thrombomodulin (rTM) has been available in Japan since 2008, but there is concern about its association with postoperative hemorrhage. The efficacy and safety of rTM were examined in patients with disseminated intravascular coagulation (DIC) caused by a septic condition after gastrointestinal surgery. Methods: Forty-two patients were emergently admitted to the intensive care unit after emergent gastrointestinal surgery in Kyushu University Hospital from May 2008 to April 2013. Of these patients, 22 had DIC (defined as an acute DIC score ≥4). All but three patients received treatment with gabexate mesylate (GM) (n = 9) or rTM (n = 10). The causes of sepsis were peritonitis with colorectal perforation, anastomotic leakage, and intestinal necrosis. Acute DIC score, sepsis-related organ failure assessment score, platelet count, and a variety of biochemical parameters were compared between rTM and GM recipients after treatment administration. Results: There were no significant differences between the groups for any parameter except C-reactive protein levels. The CRP level tended to be lower in the rTM group than in the GM group. Acute DIC score in the rTM group resolved significantly earlier than that in the GM group. No patient stopped the administration of rTM because of postoperative bleeding. Conclusion: rTM may be an effective therapeutic drug for the treatment of septic patients with DIC following emergent gastrointestinal surgery.
