Objective:To investigate the feasibility of the scene-guided technique of camera assistant in the left colon mobiliza-tion by cephalic middle approach in 3D laparoscopic surgery.Methods:The key points of scene-guided technique of camera assistant in the left colon mobilization by cephalic middle approach in 3D laparoscopic surgery was demonstrated with surgical pictures.From Apr.2020 to May 2022,41 patients underwent left colon mobilization in 3D laparoscopic rectal cancer surgery using the scene-guided tech-nique(scene group).From Jan.2019 to Mar.2020,37 patients underwent the same procedure using the conventional method(tradi-tional group).A comparative analysis was conducted on the time of left colon mobilization and the intraoperative blood loss between the two groups.Results:The operation time for the left colon mobilization in the scene group was(60.9±13.3)min,which was significantly less than(70.1±13.9)min in the traditional group.There were no statistical differences in intraoperative blood loss[(35.0±13.6)mL vs.(39.2±13.6)mL],number of lymph node dissected[(11.9±4.9)vs.(12.9±4.4)],postoperative hospital stay[(7.7±3.4)d vs.(8.0±4.3)d]and postoperative complications(5 vs.4)between the two groups(P>0.05).Both groups were followed up for 6-12 months,and there was no local recurrence or metastasis.Conclusions:Compared with the traditional method,the scene-guided technique of camera assistant for the left colon mobilization by cephalic middle approach in 3D laparoscopic surgery can significantly shorten the operation time,and the operator can obtain better operative fluency.
