Backgrounds:
With increase of patients with a small-sized lung cancer, there is an increasing need for minimally invasive lung segmentectomy that can preserve respiratory function. We perform S(9+)10 segmentectomy with retrograde dissection of the pulmonary vein, bronchus, pulmonary artery, in order, without interlober fissurelectomy and staple dissection of the peripheral lung parenchyma.
Methods:
Seven patients who underwent retrograde S(9+)10 segmentectomy between June, 2021 and May, 2022 in our hospital were retrospectively reviewed.
Results:
No patient was converted to the open thoracotomy, without any complications including prolonged air leakage. The average operation time was 171 minutes( range 125 to 221), amount of bleeding was 25 ml( range 0 to 75). Median duration of chest tube insertion was 4 days( range 3 to 6), length of stay after surgery was 6 days (range 5 to 9). Pathologic stage showed pT1mi in 3 patients, pT1a in 3 patients, pT2a in 1 patient. No local recurrence was seen at this time.
Conclusions:
Retrograde S(9+)10 segmentectomy is feasible and facilitates interlobar procedure at the time of repeated segmentectomy or completion lobectomy.
