Abstract:
Objective To evaluate the feasibility and effectiveness of full-size three-dimensional individual printed model (3D-IPM) for improving the patient's understanding of laparoscopic partial nephrectomy (LPN) preoperatively.Methods Between June 2015 and June 2016,37 patients with cT1 renal tumors underwent retroperitoneal LPN.The 3D individual digital models (3D-IDMs) were created using 3D medical image reconstructing and guiding system (3D-MIRGS) and the full-size 3D-IPMs were fabricated correspondingly.For each patient and his/her closest accompanying immediate family member (CAIFM),two preoperative conversations with a single surgeon were held by using patient's CT films,the entity of 3D-IPM combined with 3D-IDM demonstration separately.The preoperative levels of comprehension to the renal anatomy,mass characteristics,the upcoming PN procedure,potential complication risks and postoperative prognosis were evaluated using a self-made scoring questionnaire in the patient and CAIFM groups.Results All the fabrications of full-size 3D-IPMs were technically successful.Both in patient and CAIFM groups,the total preoperative comprehending score (total-PCS) elevated significantly by presenting 3D-IPM combined with 3D-IDM demonstration than CT films (42.7 vs.31.5 in patient group,P ＜ 0.05;44.6 vs.33.1 in CAIFM group,P ＜ 0.05).Sub-PCSs in all 5 aspects also showed a uniformed climbing pattern with the assistance of 3D-IPM combined with 3D-IDM demonstration rather than CT films.Conclusion The application of 3D-IPM combined with 3D-IDM demonstration can improve the preoperative comprehension of the patient and CAIFM to LPN with more intuitionistic and verisimilar presentation.
