SEGMENTECTOMY FOR LUNG NODULES: OUR EXPERIENCE AT AN ONCOLOGY CENTER IN SOUTH INDIA

Abstract

Background: Lung segmentectomy is a sublobar resection technique increasingly considered for select lung nodules, including primary lung cancer. However, data on segmentectomy in the Indian population remain sparse. This study presents our experience with segmentectomy at a cancer center in South India.

Methods: We conducted a retrospective analysis of patients who underwent segmentectomy for lung nodules between January 2021 and August 2024. Patients undergoing multi-organ resection or with poor pulmonary reserves were excluded. Data on surgical approach (open vs. VATS), intraoperative parameters, postoperative outcomes, histopathology, and oncological follow-up were analyzed.

Results: A total of 24 segmentectomies were performed, with a median patient age of 52 years and a median nodule size of 2 cm. VATS was used in 9 cases, with 3 conversions to open surgery. The median surgical duration was 140 minutes, with a mean blood loss of 100 mL. The median intercostal drainage duration was 3 days. Postoperative complications included hemoptysis (11 cases, managed conservatively) and air leaks (3 cases, managed with suction devices). No Clavien-Dindo grade 3 or 4 complications were observed. Histological evaluation revealed a range of pathologies, including adenocarcinoma, neuroendocrine tumors, and metastatic lesions. On follow-up, three patients with malignant disease developed distant metastases.

Conclusion: Segmentectomy is a safe and effective option for lung nodules of varied etiology, with minimal morbidity and acceptable short-term oncological outcomes. This study highlights the feasibility of segmentectomy in the Indian population and underscores the need for further research into segmental lung anatomy and surgical training.
