[Torsion of the middle lobe after right upper lobectomy of the lung; report of a case and the review of the Japanese literatures].
We report a case of torsion of the residual right middle lobe of the lung, following right upper lobectomy for lung cancer. A 71-year-old man who had medical treatment for emphysema was admitted with a lung tumor on chest computed tomography. The tumor was diagnosed as pulmonary adenocarcinoma by transbronchial biopsy. Right upper lobectomy with mediastinal lymph node dissection, and partial resection of the right lower lobe were performed. On the following day, chest X-ray showed an opacification in the right upper lung field, which gradually increased. Bronchoscopic examination revealed a stenotic middle lobe bronchus. Torsion of the middle lobe was suspected, and rethoracotomy was performed on the second postoperative day. The middle lobe was torsed 90-degree counterclockwise around its bronchovascular pedicle. A middle lobectomy was performed secondary to severe congestion. The patient was discharged in good condition on the 11th postoperative day. In reviewing the literatures including this case, 13 of 16 torsions occurred after right upper lobectomy of the lung. Thirteen patients had rethoracotomy, 10 of them underwent resection of the rotated lung. Simple detorsion was carried out in 3 patients, and 1 of them developed cerebral infarction. Lung torsion was reported to be potentially life-threatening. Therefore, fixation of a remaining lobe should be performed. Exploratory thoracotomy should be performed without delay, if lung torsion is suspected.
