The aim of this study was to evaluate the learning pattern of these systems on standardized phantom tasks. Forty-five stereo-enabled resident doctors were randomly assigned into three groups.

Thoracolaparoscopic repair of diaphragmatic hernias.

Complex long-standing diaphragmatic hernia presenting in adults is often managed through an open approach. Minimal invasive approach by either laparoscopy or thoracoscopy is limited by its ability to tackle these complex hernias with large defects and thoraco-mediastinal adhesions. Thus, standard laparoscopic or thoracoscopic approach is associated with high conversion to open approach.
