Abstrakt: Aim: To investigate the flow by numerical simulation in mechanical hydraulic models that approximates the stomach and gastric resection procedures Billroth I (BI) and Billroth II (BII). Method: Are used geometries axially symmetric non-deformable. Calculations obtain hydrodinamic sizes for all configurations of interest: normal geometry and geometries that simulate gastric resection procedures BI and BII. Results: By calculating the modulus of resistance, M and of time of emptying it has been found an acceptable flow for procedures BI (Péan), Y Roux (Y-R) and gastric resection Leger (GRL). In techniques BII, Reichel-Polya (R-P), Hoffmeister-Finsterer (H-F) the flow is far away from that of the normal geometry. Conclusions: Operations drastically alter the flow in accordance with the extent of anatomical changes. [ABSTRACT FROM AUTHOR]
