About
For the treatment of stage I-II NSCLC, two mini-invasive techniques are mostly utilized: uni-portal and three-portal VATS. In the uniportal approach, the injury on a single intercostal space could determine a lower level of pain than the three-portal approach, allowing a better postoperative course. Few studies in Literature compare these techniques, and most of them are retrospective.
The main purpose of this randomized study is to compare uni-portal VATS with three-portal VATS, in terms of postoperative pain.
Secondary objectives of the study are valutations of:
Full description
Randomized cohort clinical trial, prospectic, monocentric. Procedure of randomization: the day before the operation, with the "Random Allocation Rule" technique
Arm 1: pulmonary lobectomy and lymphoadenectomy with uni-portal VATS approach
Arm 2: pulmonary lobectomy and lymphoadenectomy with three-portal VATS approach
Misurations Total analgesic consumption, normalized to morphine milligrams, recorded in the 7 days following the operation.
The choice of cumulative analgesic consumption as parameter of primary outcome is because pain valuation with VAS is significantly affected by individual variability.
Secondary outcomes: measure of postoperative pain with NRS at 2,6,12,24 hours and at 2,3,4,5,30 days from sugery. A pain score will be assigned to each patient after the total amount of NRS.
Respiratory function will be valuated with spirometry after 7 and 30 days from surgery, and compared with pre-operative tests.
All intraoperative parameters will be compared between the two groups: operative time (skin to skin), proportion of conversions to open surgery, number of resected lymphnodes, amount of bleeding.
Postoperative complications will be analyzed: rate of prolonged air leaks, surgical site infections, cardiac rythhm disfunctions, pulmonary complications, post-thoracotomy syndrome, as well as lenght of stay at the hospital.
