To assess the overall qualities of published surgical meta-analysis and predictive factors for high qualities.All meta-analyses pertinent to surgical procedures published in year 2013 were selected from PubMed and EMBASE. The characteristics of the included meta-analyses were collected, and their reporting and methodologic qualities were assessed by the PRISMA (27 items) and AMSTAR (11 items) checklists,...
Anomalous origin the left coronary artery from the pulmonary artery (ALCAPA) is an extremely rare congenital coronary abnormality that may be difficult to diagnose by echocardiography. Most patients present with a potentially fatal illness leading to sudden cardiac death during infancy. This report describes a 15-year-old girl who had 15-year history of cardiac murmur but with no clinical symptoms...
A full-fledged surgery simulator should provide functions which really train and improve surgeonspsila skill. In this work, we comprehensively illustrate our surgery simulation system from its function, architecture and methods. Next, we evaluated our system from the doctorspsila perspective. Surveys are carried out to investigate doctorspsila experience of the system. Experiments are conducted to...
Virtual surgery has drawn a lot of attention during the past few years for its repeatability and low cost. In a virtual surgical environment, collision between organs or between organs and surgical instruments occurs frequently. Therefore, an efficient and stable method is needed to simulate these collision processes. Nevertheless, contrary to rigid solid animation where complete analytical solutions...
In this paper, we propose full-fledged minimal invasive surgery simulator under laparoscopic environment. In addition, a novel hybrid cutting technique for volumetric tetrahedral meshed soft tissue models is presented. A progressive cutting method is applied to the model's surface elements, where the core of the model is cut non-progressively. Our work combines the advantages of both subdivision methods...
