INDOCYANINE GREEN (ICG)-GUIDED THORACOSCOPIC PULMONARY SEGMENTECTOMY: INITIAL RESULTS FROM K HOSPITAL
Main Article Content
Abstract
Objective: To describe the technique and evaluate the initial outcomes of indocyanine green (ICG) fluorescence - guided thoracoscopic segmentectomy at K Hospital. Patients and Methods: This was a retrospective case series of 10 patients with stage IA non-small cell lung cancer who underwent single-port video-assisted thoracoscopic segmentectomy with ICG guidance at the Department of Thoracic Surgery, K Hospital, from June to July 2025. Data collected included clinical characteristics, surgical details, and postoperative outcomes. Descriptive statistical methods were used for data analysis. Results: All 10 patients were diagnosed with stage IA lung adenocarcinoma and successfully underwent surgery. The rate of intersegmental plane (ISP) identification using ICG was 100%. The mean operative time was 87.9 minutes, and the mean estimated blood loss was 41 mL. No intraoperative or 30-day postoperative mortality was recorded. One case of prolonged air leak was observed, graded as Clavien-Dindo II. The mean number of dissected lymph nodes was 8, with no lymph node metastases detected in any case. Conclusion: ICG fluorescence-guided thoracoscopic segmentectomy is a feasible, safe, and effective technique that allows precise identification of the intersegmental plane and ensures complete oncologic resection. These initial results suggest that the technique has the potential for wider application in thoracic surgery centers in Vietnam.
