Perceptions of porta-celiac vascular models for hepatic surgery and their use in residency training.

BACKGROUND: Primary aspect of hepatic navigation surgery is the identification of source vascular details to preserve healthy liver which has a vascular anatomy quite challenging for the young surgeons. The purpose was to determine whether three-dimensional (3D) vascular pattern models of preoperative computed tomography (CT) images will assist resident-level trainees for hepatic surgery. METHODS: This study was based on the perception of residents who were presented with 5 different hepatic source vascular patterns and required to compare their perception level of CT, and 1:1 models in terms of importance of variability, differential of patterns and preoperative planning. RESULTS: All residents agree that models provided better understanding of vascular source and improved preplanning. Five stations provided qualitative assessment with results showing the usefulness of porta-celiac models when used as anatomical tools in preplanning (p = 0.04), simulation of interventional procedures (p = 0.02), surgical education (p = 0.01). None of the cases had scored less than 8.5. Responses related to understanding variations were significantly higher in the perception of the 3D model in all cases, furthermore 3D models were more useful for seniors in more complex cases 3 and 5. Some open-ended answers: "The 3D model can completely change the operation plan" One of the major factors for anatomical resection of liver transplantation is the positional relationship between the hepatic arteries and the portal veins. CONCLUSION: The plastic-like material presenting the hepatic vascularity enables the visualization of the origin, pattern, shape, and angle of the branches with appropriate spatial perception thus making it well-structured.

Patient-centered oncosurgical planning with cancer models in subspecialty education.

BACKGROUND: A fundamental aspect of oncosurgical planning in organ resections is the identification of feeder vessel details to preserve healthy organ tissue while fully resecting the tumors. The purpose of this study was to determine whether three-dimensional (3D) cancer case models of computed tomography (CT) images will assist resident-level trainees in making appropriate operative plans for organ resection surgery. METHODS: This study was based on the perception of surgery residents who were presented with 5 different oncosurgical scenarios. A five-station carousel including cases of liver mass, stomach mass, annular pancreas, pelvic mass and mediastinal mass was formed for the study. The residents were required to compare their perception level of the cases with their CT images, and 3D models in terms of identifying the invasion of the mass, making differential diagnosis and preoperative planning stage. RESULTS: All residents have given higher scores for models. 3D models provided better understanding of oncopathological anatomy and improved surgical planning. In all scenarios, 70-80% of the residents preferred the model for preoperative planning. For surgical choice, compared to the CT, the model provided a statistically significant difference in terms of visual assessment, such as tumor location, distal or proximal organotomy (p:0.009). In the evaluation of presacral mass, the perception of model was significantly better than the CT in terms of bone-foramen relationship of chondrosarcoma, its origin, geometric shape, localization, invasion, and surgical preference (p:0.004). The model statistically significantly provided help to evaluate and prepare the case together with the colleagues performing surgery (p:0.007). Commenting on the open-ended question, they stated that the tumor-vessel relationship was clearly demonstrated in the 3D model, which has been very useful. CONCLUSIONS: With the help of 3D printing technology in this study, it is possible to implement and evaluate a well-structured real patient scenario setup in cancer surgery training. It can be used to improve the understanding of pathoanatomical changes of multidisciplinary oncologic cases. Namely, it is used in guiding the surgical strategy and determining whether patient-specific 3D models change pre-operative planning decisions made by surgeons in complex cancer mass surgical procedures.

Cross-cultural adaptation of the Fresno Test for Turkish language.

OBJECTIVE: National and international medical organizations and boards have recognized the importance of Evidence Based Medicine (EBM) and emphasized that EBM training should be included in medical education programs. Although some Turkish medical schools have developed and implemented EBM training programs, no validated Turkish language assessment tool has been available to compare the effectiveness of these training programs to national or international standards. The aim of this study is to cross-culturally adapt the Fresno Test, which is a validated English language tool utilized worldwide in the assessment of EBM training. METHODS: This study is a cross-sectional validation study, which was performed in two stages: Cross-cultural adaptation of the Fresno Test into Turkish; and evaluation of the psychometric properties, validity, reliability and responsiveness, of the Turkish version of the Fresno Test. RESULTS: The content validity of the test was evaluated by experienced physicians in the field of Evidence-Based Medicine, and the content validity index was 1.00. The Cronbach α coefficient was 0.78 on the post-test results. The intraclass correlation (ICC) coefficient and the kappa analysis were calculated to evaluate inter-rater reliability. The ICC coefficients ranged from 0.66 to 0.97 for pre- and post-test results. The Kappa coefficients were 1.00 for all pre-test and post-test questions except one post-test question which was 0.89. The change score of the Fresno Test was used to evaluate responsiveness. The students' score of the Turkish Fresno Test was 49.9 ±18.2 pre-training and 118.9 ±26.3 post-training with a change of 69 points (95% CI, 63.9-74.2). The Cohen's effect size was 3.04 (95% CI, 2.6-3.5) indicating a very large change in scores. CONCLUSIONS: The Turkish adapted Fresno Test used to evaluate students' success and program effectiveness is a valid and reliable measurement tool. It will be of great benefit for the comparison of the effectiveness of Turkish education programs nationally and cross-culturally.

Surgical planning with patient-specific three-dimensional printed pancreaticobiliary disease models - Cross-sectional study.

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. This study has been planned based on the fact that research on 3D printing in pancreaticobiliary disease is limited due to lack of studies on validation of model accuracy. METHODS: This is an innovative study where general surgery residents are presented 5 distinct hepatopancreatobiliary disease scenarios to generate a perception and required to compare their perception level of these cases with magnetic resonance cholangiopancreatography (MRCP), 3D images and 1:1 solid models that the pathology, diverse diagnosis and presurgery diagnosis stages can be observed. This study is single-centered. RESULTS: The dilated pancreaticobiliary intervention based on scenarios for general surgery residency was more original since there was no prior study that includes both model building and the evaluation of the perception created by the model. Five scenarios provided qualitative assessment with results showing the usefulness of 3D models when used as clinical tools in preoperative planning, simulation of interventional procedures, surgical education, and training. The perception level in the 3D model, MRCP (Z: 3.854, p: 0.000) and the 3D image (Z: 2.865, p: 0.004) was higher; likewise, the 3D-STL image was higher compared to the MRCP image (Z: 3.779, p: 0.000). All subspecialists agree that 3D models provided better understanding of dilated pancreaticobiliary pathoanatomy and improved surgical planning. CONCLUSIONS: A thoroughly outlined genuine patient situation layout aimed for general surgery training can be installed and monitored with the support of 3D printing technology of this study. This can be utilized to develop the comprehension of pathoanatomical variations of complex pancreaticobiliary illness and to adopt a surgical approach.

Health anxiety and cyberchondria among Ege University health science students.

It is common among health science students to incorrectly believe that they have contracted certain diseases they have recently studied. This can also be seen in the form of health anxiety and investigating health-related information via the internet. Health anxiety, cyberchondria and affecting factors are determined among health science students. The study was conducted at the faculties of Medicine, Pharmacy, Dentistry and Nursing in 2016-2017 with the participation of 874 students. The data were gathered using a questionnaire as well as health anxiety and cyberchondria severity scales. In the presence of a health problem, 14.2% of students seek health information via the internet. 83.7% use mobile phone to access the internet, » of students conduct health scanning once a week or more. To 65.4%, internet information is correct at medium and above level. No statistically significant difference was found with respect to students' gender, high school, places they lived before, parents' education and scales' scores. The cyberchondria scores of students with health problems are higher in the whole scale and in "distress and mistrust of medical professional" subscales. As the frequency of scanning on the internet increases, the scores of cyberchondria also increase significantly. Medical students had significantly higher scores in "distress, excessiveness and reassurance" subscales. Male students' "mistrust of medical professional and compulsion" subscales scores were also higher. It was determined that the presence of the health problem was effective on the cyberchondria. Identification of somatoform problems like health anxiety and cyberchondria may help to regulate the education program.

Web-based teaching video packages on anatomical education.

BACKGROUND: The aim of this study was to study the effect of web-based teaching video packages on medical students' satisfaction during gross anatomy education. The objective was to test the hypothesis that individual preference, which can be related to learning style, influences individual utilization of the video packages developed specifically for the undergraduate medical curriculum. METHODS: Web-based teaching video packages consisting of Closed Circuit Audiovisual System and Distance Education of Anatomy were prepared. 54 informative application videos each lasting an average 12 min, competent with learning objectives have been prepared. 300 young adults of the medical school on applied anatomy education were evaluated in terms of their course content, exam performance and perceptions. A survey was conducted to determine the difference between the students who did not use teaching packages with those who used it during or after the lecture. RESULTS: A mean of 150 hits for each student per year was indicated. Academic performance of anatomy has been an increase of 10 points. Positive effects of the video packages on anatomy education have manifested on the survey conducted on students. The survey was compiled under twenty different items including effectiveness, providing education opportunity and affecting learning positively. Additionally, the difference was remarkable that the positive ideas of the second year students on learning were statistically significant from that of the third year students. CONCLUSION: Web-based video packages are helpful, definitive, easily accessible and affordable which enable students with different pace of learning to reach information simultaneously in equal conditions and increase the learning activity in crowded group lectures in cadaver labs. We conclude that personality/learning preferences of individual students influence their use of video packages in the medical curriculum.

Anxiety of first cadaver demonstration in medical, dentistry and pharmacy faculty students.

Anatomy is the fundamental of medical and health professional education. Anatomic dissection enables the examination of the organs in the human cadavers systematically and topographically. The aim of this study was to determine the effect of the first cadaver demonstration and the anxiety of medical, dental and pharmacy students. A questionnaire was distributed to 486 students in the same academic year (2009-2010) at Ege University. The review of anxiety reveals the circumstances such as exhaustion, stress, depression, anxiety, destructive life, deterioration of mental or physical quality or asthenia (over-fatigue), professionally having a serious effect on the students. 486 (85.3 %) students in total participated in this research carried out as based on voluntariness as 338 (93.9 %) students from the medical faculty, 78 (70.9 %) students from the faculty of dentistry and 70 (70 %) students from the faculty of pharmacy.A medium level of anxiety was detected in the students in their first encounter with the cadaver. The state anxiety score (SAS) average taken by all the students who took part in the research is 42.6 ± 5.60 and trait anxiety score average is 46.6 ± 5.0. No discrepancy was detected among the faculties with respect to anxiety score. While the SASs of the male students were higher than the girls, the trait anxiety scores of the girl students were detected to be higher than male students. While the characteristics and the cultural life of our society force the male students into stronger behavioral patterns, they may actually increase their anxiety level in distressed conditions. The fact that trait anxiety is high in both sexes, particularly in female students can be explained by the patient responsibility and the work load undertaken in the professions in the medical field as early as the period of education.Before the students' applied lessons with the cadavers start, a preparatory session must be planned for this education to decrease the anxiety level by sharing their sensations, feelings and perceptions related to the demonstration.
