Inferior pulmonary ligament division during left upper lobectomy causes pulmonary dysfunction.

ABSTRACT:

Objectives

The division of inferior pulmonary ligament (IPL) during upper lobectomy (UL) was believed to be mandatory to dilate the remaining lung sufficiently. However, the benefits, especially postoperative pulmonary function, remain controversial. This study aimed to evaluate whether IPL division leads to pulmonary dysfunction.

Methods

This retrospective study included 213 patients who underwent UL between 2005 and 2018. They were categorized into an IPL division group (D group, n = 106) and a preservation group (P group, n = 107). Postoperative dead space at the lung apex, pulmonary function and complications were assessed using chest X-rays and spirometry. Changes in bronchial angle, cross-sectional area and circumference of the narrowed bronchus on the excised side wer
