[Pouches of the upper gastrointestinal tract]

The own findings about the functional behavior of the gastric substitute together with the results from the literature demand a jejunal J-pouch after gastrectomy, if it is not a palliative resection. It is an open question, whether the good experience with the Roux-en-Y-pouch-reconstruction--only 15 min. more time of operation, low rate of complications--allows a wider indication for this procedure.
