Fig. 1. Stomach volumes were mea-sured by CT volumetry with 3D re-construction. CT examinations were performed after administering efferve-scent granules. Variables measured included total sleeve volume (TSV), tube volume (TV), antral volume (AV), and tube/antral volume ratio (TAVR). TSV was defined as total sleeve volume from the top of a staple line to the pylorus; TV as the volume of the sleeve portion from the top of the staple line to incisura angularis; AV as the volume of the sleeve portion from incisura angularis to pylorus; and TAVR was defined as TV/AV.
