Role of computer analysis in prediction of surgical outcome after Billroth II gastric resection

Abstract

This paper presents computer analysis of how geometry of reconstructed gastrointestinal tract can influence outcome of Billroth II gastric resection. We performed threedimensional computer simulation in order to predict duodenal stump blowout. For creation of initial three dimensional FE models of preoperative gastroduodenal region we used data from Multi Slice Computer Tomography (MSCT). Using the initial model we performed virtual gastric surgery. All post operational models were examined separately in order to find correlation between post operational geometry and pressure in duodenal stump. Data acquired by methodology presented in this study can be valuable to surgeons for prediction of suture dehiscence after gastric surgery.
