Transect the rectal canal with the traditional approach and the GPB approach. a The angle of inclination between the stapler and the rectum without GPB ligation. â–³1 the angle between the transection line by the traditional approach and the GPB approach. b Marking the right edge of the rectal canal with a clip along the transection line in the traditional method. c The linear stapler is perpendicular to the major axis of rectal canal with the GPB to pull the rectum. d Without the GPB ligation, the total length of cartridges is a oblique line (blue line). After using the GPB, the total length of cartridges decreases (yellow line)
