Association of no epidural analgesia with postoperative morbidity and mortality after transthoracic esophageal cancer resection.

BACKGROUND: The aim of this study was to compare morbidity and mortality of patients who had epidural analgesia for at least 2 days after transthoracic esophagectomy for cancer with those who did not have epidural analgesia at all or who had it for less than 2 days.

STUDY DESIGN: We analyzed 182 patients, 7 of whom were excluded. Patients were divided into two groups; 90 patients (51%) with epidural analgesia for at least 2 days (epidural group) and 85 patients (49%) who did not have epidural analgesia or had it for less than 2 days (no epidural group). To identify prognostic factors for pneumonia, univariate and multivariate logistic regression analyses were performed.

RESULTS: There were no notable differences in clinicopathologic characteristics or intraoperative measurements. In favor of the epidural group, marked differences were found in pneumonia (28% versus 48%, p = 0.005), reintubation (17% versus 34%, p = 0.011), ICU-stay (median 2.8 versus 5.8 days, p = 0.001), hospital stay (median 17 versus 21 days, p = 0.015), and in-hospital mortality (0 versus 8 patients, p = 0.003). No epidural analgesia (odds ratio [OR] 2.48, 95% CI 1.30 to 4.71, p = 0.006) and atelectasis (OR 2.06, 95% CI 1.08 to 3.90, p = 0.028) were independent predictors for pneumonia. There were eight in-hospital deaths.

CONCLUSIONS: No epidural analgesia for more than 2 days after a transthoracic esophageal cancer resection is associated with increased postoperative morbidity. To optimize postoperative recovery, it is of vital importance to ensure adequate epidural analgesia in these patients.
