    Abstract:
    This study was conducted to examine the effects of surgical stress on changes in polymorphonuclear leukocyte elastase (PMNE) levels, and to evaluate the relationship of these changes to the development of postoperative complication. A total of 69 patients who underwent alimentary surgery were subsequently divided into three groups: a complicated group, comprised of 25 patients; an uncomplicated group with a high blood loss (H) of more than 1000 ml, comprised of 18 patients; and an uncomplicated group with a low blood loss (L) of less than 1000 ml, comprised of 26 patients. The changes in the levels of PMNE, fibronectin (FN), and antithrombin III (AT III) were compared among these three groups. In the uncomplicated H and L groups the PMNE levels rose significantly on postoperative day (POD) 1. On POD 3, high levels of PMNE were still evident in the uncomplicated H group, but a decline was observed in the uncomplicated L group. From POD 7 onwards the levels decreased to the preoperative values in both uncomplicated groups; however, the complicated group continued to show high levels even on POD 14. Significantly decreased FN levels were observed for the first 3 PODs in each group. The uncomplicated H and L groups regained their preoperative levels on PODs 7 and 14, respectively, but no recovery was found in the complicated group. The AT III levels showed similar changes to the FN levels in all groups. These findings indicate that monitoring the PMNE levels could be a useful index for the early detection of postoperative complications following alimentary surgery.
