The aim of this study was to estimate the range of mechanical properties of the human stomach in order to use the collected data in numerical modelling of surgical stapling during resections of the stomach. The biomedical tests were conducted in a self-developed tensile test machine. Twenty-two fresh human stomach specimens were used for the experimental study of its general strength. The specimens were obtained from morbidly obese patients on whom sleeve gastrectomy was performed. Finally, data on mechanical properties of the stomach wall with detailed analysis of anatomical regions of the stomach have been presented.
