BACKGROUND: Major @entity130 (MVI) is a dangerous complication associated with laparoscopic surgery that leads, if not properly handled, to @entity190 , conversion to open surgery, and eventually death. In this paper, we describe the preliminary evaluation of the SimPORTAL MVI model, created with the goal of simulating an intra-corporeal injury to a large vessel. METHODS: For this study, we created MVI models for 17 residents (PGY 1-4). Each resident was asked to perform an intracorporeal knot on a penrose drain within a maximum time limit of 6  min (in accordance with European basic laparoscopic urological skills rules) and then to subsequently repair a @entity130 on the MVI model, which was perfused with synthetic blood, within a maximum @entity190 of 3  L. During the vessel repair, low lights and pulse sounds were used to simulate the operating room environment. All @entity1 filled out a survey pre- and post-task to score various aspects of the model. RESULTS: We successfully created a model that simulates a critical surgical event. None of the @entity1 reported having previous experience repairing a MVI. Six @entity1 were able to perform the intracorporeal knot, and 12 residents (70.5  %) were able to repair the MVI model under the given time and @entity190 limits. Eleven @entity1 agreed that the MVI model behaves like a real vessel, and six felt to be capable of performing the task prior to attempting it. Sixteen @entity1 thought that the MVI model should be part of laparoscopic curriculums during residency. CONCLUSIONS: The SimPORTAL MVI model is a feasible low-cost model that would be well appreciated as a part of laparoscopic curriculum for residents. Minor improvements, including pressure measurement in the vessel for task assessment, will be made in the future, and further studies are necessary to definitively validate this model.
