COPD chronic obstructive pulmonary disease; RUL right upper lobe; RML right middle lobe; RLL right lower lobe; LUL left upper lobe; LLL left lower lobe; AIS adenocarcinoma in situ; MIA minimally invasive adenocarcinoma; IAC invasive adenocarcinoma
^aBasic diseases include hypertension, diabetes, malignancy, bronchiectasis, and COPD
^bCorrection P = 0.005
^cEasy segmentectomy is defined as resection of only one intersegmental plane, including LS1 + 2 + 3, LS4 + 5, LS6, LS8 + 9 + 10, RS6, and RS7 + 8 + 9 + 10. Rest of them is defined as difficult segmentectomy
