Summary

This study compares two surgical approaches for patients with severe Chronic Obstructive Pulmonary Disease (COPD) and severe emphysema: unilateral (operating on one lung) versus bilateral (operating on both lungs) lung volume reduction surgery (LVRS).

Conditions

  • Emphysema, Pulmonary

Interventions

PROCEDURE

Unilateral LVRS

Both unilateral and bilateral LVRS are done with a standardized 3 port VATS access. Lower ligament is freed, no graspers on the parenchyma and stapling of the selected areas with a Signia™ powered stapler with Tri-Staple™ technology (Medtronic). The reloads will not be butressed and it will be vascular or parenchymal reloads. Two drains will be placed on the operated side and the same pain management will be applied including perioperative blocs and a pain catheter. The unilateral procedures will be performed with the patient in a side position. Postoperatively the drains will be removed when there is no sign of air leakage on the digital chest drain system. Chest x-ray will be performed to secure a fully inflated lung before discharge.

PROCEDURE

Bilateral LVRS

Both unilateral and bilateral LVRS are done with a standardized 3 port VATS access. Lower ligament is freed, no graspers on the parenchyma and stapling of the selected areas with a Signia™ powered stapler with Tri-Staple™ technology (Medtronic). The reloads will not be butressed and it will be vascular or parenchymal reloads. Two drains will be placed on the operated side and the same pain management will be applied including perioperative blocs and a pain catheter. In the bilateral procedures the paBent will be positioned on the back and the side to be operated on liked by rotating the table. The surgeon is free to decide which side to deal with first. Postoperatively the drains will be removed when there is no sign of air leakage on the digital chest drain system. Chest x-ray will be performed to secure a fully inflated lung before discharge.
