“…A recently published article published by Van Berckelaer studied the possibility of discarding the dissection of the sentinel lymph node using the staging of the ultrasound and of the biopsy (FNA). The results confirm the working hypothesis, establishing the sensitivity of 75%, 100% specificity, and 92% accuracy of the method (16).…”

Scopul studiului este de a determina acurateţea examinării ecografice preoperatorii a axilei în evaluarea statusului limfonodulului santinelă la pacientele cu carcinom mamar. Materiale şi Rezultate: Din cele 54 paciente evaluate, examinarea ecografic a axilei a evidenţiat limfonoduli vizibili în 35 de cazuri din care în 15 cazuri au fost prezente metastaze. În 19 cazuri, examinarea ecografică nu a evidenţiat limfonoduli axilari vizibili, iar în 3 din aceste cazuri au fost prezente metastaze. Rezultatele studiului demonstrează faptul că nici diametrul maxim (p=0.738 test Fisher) şi nici raportul dintre axa longitudinală şi cea transversală (p=0.728 test Fisher) nu pot prezice statusul limfonodulului santinelă. Concluzie: Examinarea ecografică a axilei la pacientele cu carcinom mamar nu poate prezice statusul limfonodulului santinelă.

“…If based on morphologic criteria, the sensitivity and specificity are 26%À76% and 88%À98%, respectively. Most of the previous studies testing ultrasound efficacy evaluated the entire axilla, and the diagnostic criteria of lymph node metastasis included shape, size, longitudinal-to-transverse axis ratio (L/T), cortical morphology and hilum and blood flow status (Saffar et al 2015;Van Berckelaer et al 2016;Akissue de Camargo Teixeira et al 2017;Schwentner et al 2017). While not evaluating the association between ultrasound features and pathology of individual single lymph nodes, this design has an obvious drawback: the ultrasound features of a single lymph node are not used to predict its specific pathology, which may result in prediction bias.…”

Ultrasound diagnosis of axillary lymph nodes has the advantages of ease, convenience and low cost; however, most previous studies evaluated lymph node metastasis of the entire axilla rather than the association between the ultrasound features of a single lymph node and its pathology. This prospective study was performed to explore the ultrasound features of lymph nodes observed in bionic medium in vitro and to develop a lymph node-specific model for prediction of metastasis based on analysis of the association between the ultrasound features and pathology of each lymph node.

“…In this context, medical students could have a tool to easily visualize patient-specific anatomical 3D models instead of going into operating and/or dissection rooms and attending a huge number of surgeries before becoming familiar with all common anatomical variations. 51 Our VRE did not allow user interaction in terms of cutting, assembling, and suturing of the 3D virtual organs. Therefore, it was easy to explain the lowest points given to the item considering the utility for teaching surgical procedures to trainee surgeons (mean: 3.77 over 5).…”

Introduction. With the availability of low-cost head-mounted displays (HMDs), virtual reality environments (VREs) are increasingly being used in medicine for teaching and clinical purposes. Our aim was to develop an interactive, userfriendly VRE for tridimensional visualization of patient-specific organs, establishing a workflow to transfer 3-dimensional (3D) models from imaging datasets to our immersive VRE. Materials and Methods. This original VRE model was built using open-source software and a mobile HMD, Samsung Gear VR. For its validation, we enrolled 33 volunteers: morphologists (n = 11), trainee surgeons (n = 15), and expert surgeons (n = 7). They tried our VRE and then filled in an original 5-point Likert-type scale 6-item questionnaire, considering the following parameters: ease of use, anatomy comprehension compared with 2D radiological imaging, explanation of anatomical variations, explanation of surgical procedures, preoperative planning, and experience of gastrointestinal/neurological disorders. Results in the 3 groups were statistically compared using analysis of variance. Results. Using cross-sectional medical imaging, the developed VRE allowed to visualize a 3D patient-specific abdominal scene in 1 hour. Overall, the 6 items were evaluated positively by all groups; only anatomy comprehension was statistically significant different among the 3 groups. Conclusions. Our approach, based on open-source software and mobile hardware, proved to be a valid and well-appreciated system to visualize 3D patient-specific models, paving the way for a potential new tool for teaching and preoperative planning.
