title: Prophylactic middle lobe fixation for postoperative pulmonary torsion.
abstract: Background To prevent postoperative middle lobe torsion after a right upper lobectomy, we introduced a novel technique of interlobar fixation using collagen fleece coated with fibrin. In this study, the prophylactic effects of this method on the incidence of postoperative pulmonary torsion were analyzed. Methods Between April 2001 and December 2015, 3786 pulmonary resection procedures (excluding total pneumonectomy) were performed in our institution, and prophylactic interlobar fixation was selectively applied when intraoperative examination indicated that the patient was at high risk of postoperative pulmonary lobe torsion. As a control group, 842 patients who underwent pulmonary resection procedures between January 1996 and April 2001 were reviewed. Results During the study period, 10 (0.3%) patients underwent prophylactic middle lobe fixation (to the lower lobe after a right upper lobectomy in 9, and to the upper lobe after a right lower lobectomy in one). Pulmonary lobar (middle lobe) torsion occurred in only one patient (after right upper lobectomy); thus the incidence of this complication was 0.1% among patients who underwent a right upper lobectomy and 0.03% among all pulmonary resection procedures. The rates during the study period were marginally significantly lower than those in the control period (1.3% and 0.24%, respectively; p = 0.071 and p = 0.087, respectively). Conclusion Prophylactic middle lobe fixation might be useful for preventing postoperative pulmonary middle lobe torsion.
