Who can take part
- Age group 18-70 years old
- Any mass in the upper lobe presented for upper lobectomy
- Patients presented for bilobectomy for whatever cause
- Preoperative ECOG score of 0-1, preoperative ASA scores 1-2
Who cannot take part
- Severe thoracic adhesions found during surgery

About the trial
What the trial wants to find out
This study looks at two different surgical techniques used during lung surgery (upper lobectomy). Surgeons may either divide or preserve a thin tissue band called the pulmonary ligament. The investigators want to understand how this choice affects recovery, including changes in lung size, airway shape, and symptoms such as cough. Forty patients took part, with half receiving ligament division and the other half with ligament preservation post upper lobectomy. Lung volume and airway changes were measured using CT scans, and cough scores were recorded after surgery. The study also noted one patient in the division group who developed a space problem (pneumothorax) two weeks after surgery. The goal is to learn which approach may help patients recover more comfortably and reduce postoperative symptoms.
