Introduction: Lobar torsion is a rare but fatal complication, with such cases being mostly treated with pulmonary resection. Only a few cases of pulmonary torsion following esophagectomy have thus far been reported, and all cases occurred subsequent to transthoracic esophagectomy. Case presentation: We herein present the case of a patient with the right middle lobe torsion after thoracoscopic esophagectomy in a 64-year-old male.As the patient exhibited a hemodynamically unstable condition immediately after surgery and bronchoscopy and computed tomography revealed right middle lobe torsion, urgent surgery was performed.As torsion of right middle lobe was confirmed during a second operation, repositioning for torsion was performed. Fortunately, right middle lobe was aerated and exhibited a good complexion immediately after repositioning; therefore, pneumonectomy was not performed. Conclusion: Because it is difficult to observe the process of reinflation of a collapsed lung under direct vision in order to prevent lobar torsion when performing thoracoscopic esophagectomy, it is imperative to confirm the patency of the proximal bronchi during the operation using bronchoscopy.
