Minimally invasive and standardized thoracoscopic surgery for stage III empyema using a variable-view rigid endoscope

Thoracoscopic surgery for stage III acute empyema is often limited by poor visualization and anatomical complexity. We developed a standardized, minimally invasive approach using a variable-view rigid endoscope and fixed port placement, regardless of disease extent or patient physique. The variable-view endoscope enabled a wide, adjustable field of view without moving the camera shaft, allowing safe access even in the confined thoracic space. This setup facilitated comprehensive adhesiolysis and decortication via a bidirectional approach by surgeons on both ventral and dorsal sides. Among 43 consecutive patients, all but one underwent successful thoracoscopic management, with favorable clinical outcomes and minimal complications.
