The theoretical calculation with laparoscopic and 3D-MSCT validation of the volume measurement method for a gastric pouch in gastric bypass surgery

The authors proposed a method for calculating gastric pouch volume based on its geometric shape, validated using visual laparoscopic and 3D-MSCT measurements. The method simplifies the calculation of the volume of the created gastric reservoir. This method can be reproduced and used in further studies on gastric pouch measurement.
