Abstract
Object :Single port Lobectomy is less traumatic and may expect a lower postoperative pain rather than multi- portVATS lobectomy. In this study we analyzed perioperative outcomes of single port and multi-port VATS lobectomy
Method: We analyzed retrospectively 19 consecutive patients undergoing VATS lobectomy for lungcancers(n=15) or inflammatory lungs(n=4) from December 2013 to November 2015. Variables included age, gender, operation time,intensity of pain(assessed by VAS score), medication, and hospital stay.
Result :The operation type were 6 single port lobectomies and 13 multi-port lobectomies. Persistent air leak occurred in 1patients with multi-port VATS. There were no significant difference in VAS score(S=1.83;M=2.53), the median duration of IV PCA(S=4days;M=4.2days) and additional injection(S=2.8times;.M=1.3times). Mean hospital stay has been 8.3days(S=6.8days;M=9.0days)
Conclusion: Single port VATS lobectomy may be feasible for lung cancers and inflammatory lungs. But further investigation is necessary.
