Subcostal Specimen Removal in Completely Portal Robotic Lobectomy

Subcostal Specimen Removal in Completely Portal Robotic Lobectomy

This protocol describes the removal of lung specimens following a completely portal robotic lobectomy. Determining the optimal location for specimen extraction is a pertinent question, as both intercostal and subcostal routes can serve as potential extraction paths following robotic or video-thoracoscopic lobectomy. We choose subcostal lung specimen removal over intercostal...
