Impact of transhiatal esophagectomy on cardiac and respiratory function

Abstract

We studied the impact of transhiatal esophagectomy on the cardiac and respiratory function of 44 consecutive patients. Preoperatively, 31 patients had associated medical problems (22 with cardiac disease, 31 with pulmonary disease). Mean forced expiratory volume in 1 second (FEV1) was 2.1 liters, but it was less than 1.2 liters in six patients. Postoperatively, mechanical ventilation was given for a mean of 49 hours. Of the six patients with FEV1 less than 1.2 liters, five were ventilated for an average of 44 hours, and one was ventilated for 221 hours. Intraoperative hypotension, which averaged 8 minutes, was longer in patients with a history of cardiac disease (10 of 14 patients) and in those with a midesophageal tumor (9 of 14 patients). Atrial arrhythmias (14 patients) were more common in patients with a history of cardiac disease and were all successfully treated medically. Nine patients developed congestive heart failure, and they all recovered. Average hospital stay was 15 days. Transhiatal esophagectomy has a greater impact on pulmonary and cardiovascular physiology than previously believed, but the majority of complications can be treated successfully. Transhiatal esophagectomy can be performed safely in patients with poor respiratory function, who constitute about 10% of those who need esophageal resection.
