Robotic single right anterior medial (S3b) subsegmentectomy for early primary lung cancer in a patient with a small...

Subsegmentectomy is an optional treatment for early primary lung cancer presenting without adequate surgical margins for wedge resection. There are no previous reports regarding a robotic single subsegmentectomy. We report a robotic single subsegmentectomy of the right anterior medial subsegment (S3b). The lung parenchyma was dissected with a Vessel Sealer Extend along the intersubsegmental veins for proper lung mobilization to solve the directional limitations of the robotic stapler. Additionally, we inserted the most ventral port from the subcostal region to increase the distance between the ports. Performing a robotic single subsegmentectomy is challenging. However, our techniques help to achieve a safe and effective operation.
