Abstract

Peripheral benign lung tumors are often asymptomatic and incidentally detected on chest radiographs. Surgical intervention is recommended when feasible. Single-port thoracoscopic resection has emerged as a promising technique for treating various chest diseases, including lung tumors. This study aimed to assess the clinical efficacy of single-port thoracoscopic resection for benign lung tumors and its impact on respiratory function and inflammatory factors.

A total of 128 eligible patients diagnosed with benign lung tumors were randomly assigned to either the observation group (undergoing single-port thoracoscopic resection) or the control group (undergoing conventional thoracic surgery). Surgical outcomes, complications, pulmonary and respiratory function, and inflammatory factors were compared between the two groups.

The observation group showed significantly lower intraoperative bleeding, shorter hospitalization time, and lower complication rates compared to the control group. Patients in the observation group exhibited higher vital capacity (VC), forced vital capacity (FVC), and total lung capacity (TLC) levels at 1/2 week and 1 month after surgery. Additionally, forced expiratory volume in one second (FEV1) and maximum ventilation volume per minute (MVV) levels were higher in the observation group post-surgery, with a lower Borg score. Levels of C-reactive protein (CRP), precalcitonin (PCT), and tumor necrosis factor (TNF-α) were lower in the observation group post-surgery.

Single-port thoracoscopic resection demonstrates favorable clinical efficacy for treating benign lung tumors, reducing bleeding, and shortening hospital stays. Furthermore, it improves lung and respiratory function while reducing inflammatory factors. This technique is safe, effective, and holds promise for wider application in managing benign lung tumors.
