BACKGROUND: Esophagectomy is associated with pulmonary complications. This study evaluated if thoracoscopic minimally invasive esophagectomy (MIE) mitigates these risks by comparing pulmonary findings on postoperative computed tomography (CT) between open esophagectomy and MIE.
METHOD: Postoperative (day 5) thoracic CT from 40 patients (20 open and 20 MIE) who had undergone esophagectomy with epidural analgesia and right-sided thoracic drainage were reviewed. On an axial view, the areas of atelectasis and pleural effusion were measured at 1 and 5 cm above the right diaphragmatic dome and at the level of the carina. In addition, the total distribution of atelectasis and pleural effusion was estimated on an ordinal scale (0-5), with ≥3 considered clinically important.
RESULTS: The groups were well-matched in terms of age, sex, and smoking status. There were no differences in the areas of atelectasis or pleural effusion for open surgery compared with MIE. The groups did not differ in the proportion of patients with clinically important atelectasis (right: 30% vs. 25%, left: 65% vs. 65%) or pleural effusion (right: 15% vs. 15%, left: 65% vs. 45%). More pleural effusion and atelectasis at the 1-cm level was present on the left side at day 5 in both open and MIE patients.
CONCLUSION: Despite major differences in surgical trauma and ventilation strategies between open and MIE, CT evaluation at day 5 was surprisingly similar. Less right-sided pleural effusion demonstrates the effect of surgical drains. We believe that the defined levels of measurement used in this study, performed at clear anatomical landmarks, can be of value in future studies.
