Lobectomy Induces Exercise-Induced Pulmonary Hypertension and Effort Intolerance Compared With Sublobar Resection.

ABSTRACT:

Introduction

The rationale underlying the benefits of the parenchyma-preserving nature of sublobar resection (SR) compared with lobectomy remains unclear. This study aimed to assess postoperative changes in cardiopulmonary function after lobectomy and SR using exercise stress testing.

Methods

This prospective, observational study enrolled patients scheduled for lobectomy or SR. Changes in cardiopulmonary function at 6 months postoperatively were evaluated using exercise stress echocardiography and cardiopulmonary exercise tests.

Results

Initially, 41 patients were enrolled, with 20 patients in the lobectomy group and 18 patients in the SR group (16 segmentectomies, two wedge resections) after excluding three ineligible patients. Preoperatively, all patients demonstrat
