[Are leukocytes and CRP early indicators for anastomotic leakage after esophageal resection?].

BACKGROUND: Anastomotic leaks represent the most common severe postoperative complications after esophagectomy. In this study standard inflammatory laboratory parameters [leukocytes, C-reactive protein (CRP)] were evaluated as indicators for anastomotic leakage after esophagectomy. PATIENTS AND METHODS: Between 1 / 1997 and 12 / 2006 a total of 558 patients with esophageal cancer underwent an Ivor-Lewis esophagectomy. Among these patients, all those (n = 50, 8.9 %) suffering from an anastomotic leak were matched to 50 patients without anastomotic leakage. Leukocytes, CRP level and clinical parameters (body temperature, cardiac / respiratory problems, wound secretion) were retrospectively analysed at short-term intervals in both groups.
RESULTS: Patients with anastomotic leaks showed significant continuously increased CRP levels and leukocyte counts from the second or, respectively, 5 (th) postoperative day onwards compared to patients without anastomotic leaks. Using a stepwise regression, an 80 % sensitivity for leakage detection has been calculated by a cut-off value for CRP set at 13.5 mg / dL from day 2 onwards or, respectively, for leukocytes at 10.5 Gpt / L from day 8 onwards. Concomitantly, patients with anastomotic leaks suffered significantly more from respiratory problems and abdominal pain.
CONCLUSION: CRP appears to be a reliable and predictable indicator for anastomotic leakage after esophagectomy and should, therefore, be routinely used as a screening marker to provide a reason for extended diagnosis.
