Abstract:
In this study Computational Fluid Dynamics (CFD) examination of how geometry of reconstructed gastrointestinal truct can influence the postoperative results of gastric resection is presented. Three-dimensional computer simulation is used in order to perform virtual gastric resection and investigate conditions at the duodenal stump after Billroth II gastric resection which may cause duodenal stump blowout. Initial finite element model of preoperative gastroduodenal region was created using data from Multi Slice Computer Tomography (MSCT). We performed virtual gastric resection using the preoperative Finite Element (FE) model and three cases after Billroth II gastric resection. CFD calculation was performed employing these models with initial simulation parameters according to our previous investigation. We calculated pressure and velocitydistributions, as well as salivaand pancreatic juice and bile concentrations. This study offers an insight into the processes within the duodenal stump after surgical intervention, which can be useful for patient-specific predictions of a surgical outcome.
