Postoperative analgesia reduces mortality and morbidity after esophagectomy.
BACKGROUND
To study the influence of postoperative analgesia on morbidity and mortality after esophagectomy.


METHODS
The outcomes of 578 patients who underwent one-stage resection between 1986 and 1995 were analyzed. Patients who received either epidural morphine, patient-controlled analgesia, or continuous intravenous morphine infusion supervised by an anesthesiology-based acute pain service (group APS, n = 299) were compared with those for whom conventional intramuscular meperidine injections were used (group CON, n = 279).


RESULTS
For patients who underwent transthoracic esophagectomy, group APS (n = 226) had a lower incidence of pulmonary complications (13% versus 25%, P = 0.002), cardiovascular complications (21% versus 43%, P < 0.001), and hospital mortality (8% versus 14%, P = 0.038) when compared with group CON (n = 189). No similar difference was demonstrated in patients who underwent esophagectomy without thoracotomy. The hospital stay (days) was shorter in group APS than in group CON for both transthoracic esophagectomy (22 +/- 20 versus 30 +/- 37, P = 0.005) and nontransthoracic esophagectomy patients (19 +/- 13 versus 25 +/- 21, P = 0.029).


CONCLUSIONS
Adequate postoperative analgesia is associated with lower cardiopulmonary complications, lower mortality and reduced cost in patients undergoing transthoracic esophagectomy.
