Feasibility of repeated ipsilateral anatomical pulmonary resection.

Abstract

This study aimed to elucidate the feasibility of repeated ipsilateral anatomical pulmonary resection. The subjects of this retrospective analysis were 50 patients who underwent ipsilateral anatomical pulmonary resection after major lung surgery. The patients were divided into two groups according to the type of primary operation performed: a repeated anatomical pulmonary resection group (RA group; n = 24) and an anatomical pulmonary resection after wedge resection group (AW group; n = 26). We compared the perioperative outcomes of the two groups. Completion lobectomy was performed in 9 of the 24 patients (38%) from the RA group and adhesion of the pulmonary hilum was more severe in this group (P = 0.004). Although the operative time was significantly longer in the RA group (P = 0.030), there was no significant difference in the amount of blood loss (P = 0.217) between the groups. A significantly higher rate of severe postoperative complications was observed in the RA group (42%) than in the AW group (12%) (P = 0.024). None of the patients who underwent repeated surgery died within 90days postoperatively. Although repeated anatomical pulmonary resection is a more challenging procedure than anatomical resection after wedge resection, it does not increase short-term mortality; therefore, it is a feasible treatment option.
