[Lung function following sleeve bronchoplastic lobectomy for bronchogenic carcinoma]

Area of Science:

• Cardiothoracic Surgery
• Pulmonary Medicine
• Oncology

Context:

• Lung cancer treatment often involves surgical resection.
• Upper sleeve lobectomy is a lung-sparing surgical technique.
• Assessing postoperative pulmonary function is crucial for patient outcomes.

Purpose:

• To evaluate the impact of upper sleeve lobectomy on postoperative pulmonary function.
• To compare the functional outcomes of upper sleeve lobectomy with bronchoplasty, lobectomy alone, and pneumonectomy.
• To analyze the recovery pattern of pulmonary function after bronchoplasty.

Summary:

• Spirometric evaluation of 25 patients undergoing upper sleeve lobectomy for lung cancer revealed decreased Vital Capacity (VC), %Vital Capacity (%VC), and Forced Expiratory Volume in one second (FEV1.0), with an increase in FEV1.0% postoperatively.
• No significant differences in postoperative %VC or FEV1.0% were found between patients who underwent bronchoplasty and those who had lobectomy alone.
• However, patients undergoing pneumonectomy showed a significantly greater decrease in postoperative %VC compared to those who had bronchoplasty or lobectomy alone. %VC in the bronchoplasty group decreased at 3 months but returned to preoperative levels by 13-24 months.

Impact:

• Bronchoplasty appears to be a superior surgical option to pneumonectomy for preserving lung function in lung cancer patients.
• Understanding the functional changes and recovery trajectory after upper sleeve lobectomy aids in patient management and rehabilitation.
• This study highlights the importance of lung function assessment in the postoperative management of lung cancer patients undergoing different surgical resections.
