Purposes
The clinical benefits of thoracoscopic radical esophagectomy in the prone position compared to conventional open esophagectomy have not been fully documented.
Methods
Forty-six patients with esophageal cancer who underwent MIE in the prone position (MIE-P group) were enrolled, and 46 case-matched controls that underwent open esophagectomy (OE group) were identified using propensity score methods to achieve a valid comparison of outcomes between MIE and open esophagectomy.
Results
The duration of systemic inflammatory response syndrome was shorter in the MIE-P group than in OE group (P = 0.005). The time to first walking was earlier in the MIE-P group (P < 0.001). Although the vital capacity ratio (%VC) declined after the operation in both groups, the change ratio of the %VC was 85.3 % in the MIE-P group and 69.6 % in the OE group (P < 0.001). No mortality occurred in either group. The postoperative morbidity rate was lower in the MIE-P group (13 %) than in the OE group (30.4 %) (P = 0.020). Two patients (4.3 %) in the OE group and one patient in the MIE-P group (2.2 %) had pneumonia.
Conclusions
MIE in the prone position was associated with less impairment of the pulmonary function, earlier recovery of activity and lower subsequent morbidity compared to open esophagectomy. Further investigation of the long-term outcomes is, therefore, needed.
