Abstract
The authors proposed a method for theoretical calculations of the gastric pouch based on its geometric shape with visual laparoscopic and 3D-MSCT gastric pouch volumetry validation. The method allows simplifying the planning of the volume of the created gastric reservoir. This method can be reproduced and used in further studies with gastric pouch measurement.
