Abstract
BACKGROUND: Thoracoscopic complex basilar segmentectomies are technically demanding and challenging. We review our experience to check whether this complexity can lead to specific surgical issues or increased post-operative morbidity. METHODS: Complex basilar segmentectomies were defined as the anatomical resection of at least one segment composing the basilar pyramid, excluding S(6). Data of patients who had an intention-to-treat thoracoscopic complex basilar segmentectomy were retrospectively collected from 2007 to 2019: indications, preoperative assessment, clinical features, operative technical aspects and early post-operative outcome. RESULTS: Sixty-three patients, 26 men (41%) and 37 women (59%) with a median age of 66 years and a median body mass index (BMI) of 26 kg/m2 were included. Interventions performed were mostly S(9+10) (n=32) and S(8) (n=12) segmentectomies. Forty-five planned operations (71%) were completed. Extension to a larger resection was necessary in 17 patients (27%) and 4 patients underwent conversion to open surgery (6%). Median operative time was 168 minutes with a median intraoperative bleeding of 30 mL. Complications occurred in 11 patients (17%). There was no mortality. Median length of pleural drainage was 2 days (range, 1-2 days) and median hospital stay 4 days. CONCLUSIONS: The extension rate of complex basilar segmentectomy is higher than that of other sublobar resections but their post-operative morbidity is identical.
