Brief Summary

Background: Three-dimensional (3D) printing has been increasingly used in medical applications with the creation of accurate patient-specific 3D printed models in medical imaging data. However, research on 3D printing in pancreaticobiliary disease is limited with lack of studies on validation of model accuracy. Methods: This is a where general surgery residents, are introduced to 5 distinct hepatopancreatobiliary disease scenarios to generate a perception and required to compare their perception level of these cases with computed tomography (CT), 3D images and 1:1 solid models that the pathology, diverse diagnosis and presurgery diagnosis stages can be investigated.

Outcome Measures

Primary Outcomes (1)

  • compare the effectiveness of the solid model with CT screen, 3D-Standard Tessellation Language (STL) image and 1:1 scale model

    Our aim is to compare the effectiveness of the solid model with CT screen, 3D-Standard Tessellation Language (STL) image and 1:1 scale model in 5 different hepatopancreatobiliary disease scenarios to general surgery residents in terms of recognizing the pathology, differential diagnosis and preoperative preparation stages.

Interventions

surveyOTHER

Members chosen for this study group are general surgery residents. A quintet with stations composed of normal pancreaticobiliary anatomy, common bile duct tumor, stony cholecystitis, pancreatic head cancer and cholelithiasis was assembled for the study. Each station contained CT, 3D-STL images and 1:1 solid models of cases. Each imaging method associated with the scenarios of the quintet is observed by the residents of the study. An explanatory assessment measure is being used as data collection method where the perception of each imaging method is being evaluated based on their effectiveness in problem identification as well as their efficiency in diverse diagnosis and pre-surgery organization. Participants' perception of residency training was evaluated with a multi-entry survey. The focus of the survey, which was applied by our team was by domains, self determined decision-making, diverse diagnosis, academic scholarship, and scientific appraisal.

Our aim is to compare the effectiveness of the solid model with CTimage, 3Dimage and 3Dmodel in 5 different hepatopancreatobiliary disease scenarios presented to general surgery residents in terms of recognizing the pathology, differential diagnosis and preoperative preparation stages. The focus of the survey applied by our team was on domains, decision-making, diverse diagnosis, scientific appraisal. In these scenarios, normal pancreaticobiliary organs and cases leading to extrahepatic biliary tract dilatation such as choledochal tumor, acute stone cholecystitis, pancreatic head tumor and cholelithiasis were discussed. Perception of the anatomical formation, impact of the procedure to diverse diagnosis, operation arrangement and presurgical preparation assistance are the main criteria in the evaluation of every imaging procedure. Any significant differences in the measurements between the CTimages, 3Dimages and the 3Dmodel were obtained by using Wilcoxon Signed Test.
