<p>Minimally invasive anatomic pulmonary segmentectomy requires
intraparenchymal dissection for the exposure of the segmental vessels and
bronchi. This dissection is performed bluntly during video-assisted
thoracoscopic surgery (VATS), leading to increased air leak and a longer length
of stay (LOS). The robotic platform enables a meticulous dissection due to its improved
visibility, enhanced dexterity, and the more-than-human-wrist range of motion
of the robotic arm. This meticulous dissection in our small series of VATS
versus robotic segmentectomy (22 versus 28 patients, single surgeon experience)
shortened the LOS and complication rate to half (median LOS: 4 days for VATS versus
2 days for robotic surgery). This video demonstrates a robotic left lower lobe
basilar segmentectomy using the Da Vinvi Xi Robot using a four arm technique
and total robotic staplers. </p>
<p><b>Procedure</b></p>
<p>The patient was a 43-year-old woman with a body mass index of
49.5 who was incidentally found to have a left lower lobe, PET positive, 2 cm,
suspicious lesion. Her metastatic workup did not show evidence of distal
disease. Ports were placed in the eighth intercostal space with the anterior
port always placed one intercostal space more superior than compared to
lobectomy. After port placement, the dissection was started by taking down the
pulmonary ligament. The pleura was opened over the posterior surface of the
lung up to the apex, and the lymph node dissection was performed. The inferior
pulmonary vein was dissected, and the basilar and superior segment veins were
exposed posteriorly. The pulmonary artery was exposed in the fissure
posteriorly, and the basilar segment vein was isolated. Subsequently, the
dissection was performed in the fissure to expose the pulmonary artery and its
basilar and superior segment branches. The basilar segmental artery was
transected using the robotic curve tip 30 mm white staple load introduced
through the posterior arm. Similarly, the basilar vein was transected
introducing the same stapler from the posterior arm. The basilar segment
bronchus was isolated in the fissure and transected using the curve tip 30 mm
blue staple load through the posterior arm. The authors also used the robotic
stapler for the parenchymal resection. The 45 mm straight green staple load was
introduced through the posterior arm, and the parenchyma was resected in the
line of the bronchus. The specimen was placed in a bag and removed through the
assistant port. </p>
<p>The patient was extubated, and she recovered from anesthesia
without difficulty. The chest tube was removed, and the patient was discharged
home without complication 20 hours later. The final tumor pathology revealed a stage
IA invasive adenocarcinoma.</p>
