Stereotactic Navigation for Rectal Surgery: Comparison of 3-Dimensional C-Arm−Based Registration to Paired-Point Registration

This study was based on a prospective case series. SETTING: The study was conducted in a single university hospital. PATIENTS: Four patients who underwent laparoscopic rectal surgery were included. INTERVENTIONS: Paired-point registration was performed for 2 cases, whereas 3-dimensional C-arm−based registration was performed for the other 2 cases. In addition, 3-dimensional C-arm−based registration was performed twice during the operation. MAIN OUTCOME MEASURE: Navigation accuracy was evaluated by measuring target registration error at 8 anatomical landmarks. RESULTS: Target registration error of the 3-dimensional C-arm−based registration group was significantly smaller than that of the paired-point registration group (median, 19.5 mm vs 54.1 mm; p
