Core Tip

Core Tip: This prospective study evaluated the role of three-dimensional (3D) reconstruction technology in laparoscopic sigmoid colon cancer surgery. Preoperative 3D models generated via contrast-enhanced computed tomography and 3D Slicer/Mimics software guided tumor localization, vascular assessment, and lymph node dissection. Compared with the control group, the 3D group showed shorter operative time, less blood loss, earlier postoperative recovery, and higher lymph node yield, demonstrating that 3D visualization enhances surgical precision and safety in managing anatomical complexities of laparoscopic sigmoid colon cancer.
