    Abstract:
    Lingular-segment torsion after left-upper division segmentectomy (LUDS) is a rare complication, and the cause remains unclear. Here we report the case of a patient who developed lingular-segment torsion after LUDS for multiple lung metastases of breast cancer. One lung nodule was located in the S1 + 2 segment and another between the upper lobe and S6 on an incomplete interlobar fissure. The lung metastases were resected by extended LUDS using video-assisted thoracic surgery with indocyanine green fluorescence imaging. The staple line on the lingular segment was vertically tilted against the interlobar line because of the atypical defect of the fluorescence plane and nodule position. Chest X-ray and contrast-enhanced computed tomography indicated ischemia and torsion of the lingular segment on the second postoperative day, and completion of lingular segmentectomy was performed. This case showed the vertical intersegment staple line during LUDS was one of the important causes of postoperative torsion of the lingular segment.
