Abstract: Objective Describes the methods of 3D reconstruction and dimension measurement in order to help doctor in diagnosis,operation planning and the actual surgery.Methods With the help of the CT scan results, we established three-dimensional digital model of pelvis.The data of 97 cases of middle and lower rectal cancer patients were retrospectively analyzed and statistically managed.Results With multivariable analysis of the measurement data,we found the anatomic factors that were key to sphincter-preserving operation for middle and lower rectal cancer.Conclusion The application of three-dimensional digital model of pelvis can bring the surgeons new anatomic diameter and spacial measurement data,and thus give more objective evaluation about the critical restrictive role of pelvis anatomy in sphincter-preserving procedure and even in operation of pelvis.

Key words: three-dimensional visualization of the pelvis, dimension measurement, the middle and lower rectal cancer operations
