Pulmonary segmentectomy was originally introduced nearly 70 years ago for the treatment of benign lung conditions. Later, Jensik and colleagues as well as Peters independently suggested that anatomic pulmonary segmentectomy could be effectively applied to small primary lung cancers when good margins were achievable. Today, this is possible thanks to recognition of early lung cancer by high-resolution computed tomography scan. Futhermore, lung-sparing procedures are advocated in those with small, early-stage primary lung cancers so that additional resections for bilateral synchronous or metachronous primaries are facilitated.
Several advantages to endoscopic procedures relative to open procedures have been identified and include decreased postoperative pain, shortened chest tube duration and length of stay, faster return to preoperative activity levels, preserved pulmonary function, and decreased inflammatory response.
This video demonstrates the main steps of a totally endoscopic right basilar segmentectomy for stage I lung carcinoma.
