The present invention relates to the conduits of a mouth stomach of the gastrectomy longitudinal for one. The object of the present invention is to provide the conduit of a mouth stomach, indicates the alternative of an advantageous poorly suitable conduit used today, be convenient for surgical work. The conduit of this novel mouth stomach is characterized in that, this distal part carries, in the state of inflation, substantially there is a shape to match a balloon (25) for the pyloric antrum (4) to lodge in this pyloric antrum (4), it is then in the distal end of the main body of the conduit (20) to the end of the inflatable balloon (25) of the base station of pylorus (5) and in the base station to pyloric antrum (4) for their own, although the wall of the less curvature (6) against stomach (1), the Bu Fen Bei Wedged for being set to the main body (21) of the conduit (20) on inflatable balloon (25) are closed, to make the position that may determine the beginning for closing resection be lined up in the region of pyloric antrum (4), it limits and closes resection line, calibrate the sleeve of pyloric antrum (4) stomach function regulating being saved.
