As a rule we perform video-assisted thoracoscopic (VATS) anatomic segmentectomies through a biportal approach, including a 3–4 cm anterior utility incision and another 1.5 cm inferior port.
We utilize a 5 or 10 mm, 30 degree angled HD video-thoracoscope.
The surgeon and the assistant are usually positioned on the anterior (abdominal) side of the patient. The surgeon can change position and place himself cranially or caudally with respect to the assistant depending on the different steps of the operation.
Initially, the anterior utility incision is made and the wound is protected by a plastic soft tissue retractor (wound protector) kept in place by a ring in the chest cavity and one outside the skin (Alexis Retractor, Applied Medical USA). This incision is usually placed at the 4th-5th intercostal space between the tip of the scapula and the breast in the anterior axillary line.
A second 1.5 cm port is positioned more posteriorly at the level of the 7th intercostal space just anterior to a straight line down from the tip of the scapula and is performed under endoscopic guidance using the thoracoscope through the utility incision made previously.
Operative steps (Figure 1)
For a right S7+8 segmentectomy, the camera is introduced through the utility incision. Dissection starts with opening of the oblique fissure and exposure of the basilar segmental arterial branches using monopolar diathermy. Suction device is using for retraction and maintenance of a dry surgical field. The arterial segmental branch for the segment 8 (A8) is dissected and divided using endovascular stapler proximal to the origin of A7 branch. The stapler is passed through the utility incision.
The next step is the exposure of the segmental bronchus (S8+7). The bronchus is dissected with a Harken clamp and encircled with a vessel loop. We normally clamp the bronchus and request from the anesthetist to inflate the lung as demonstrated. Division of the bronchus is performed with the endoscopic stapler introduced through the utility incision. If the angle is more favorable, the stapler can be introduced through the inferior port as shown in the video.
After division of the segmental bronchi, the segmental vein for segment 8 (V8) is dissected and divided with endovascular stapler. Again the angle in the presented case favored introduction from the inferior port. Finally, the parenchyma is divided along the inflation-deflation line and the specimen is removed in an endobag. A systematic lymph node sampling is the last step of the procedure.
