The stomach is exposed through Fenger's incision, a cut is made into it, and a tube introduced and fixed by a single catgut stitch. Two parallel folds of the stomach are then raised up, one on each side of the tube, and their summits are sutured by two or three Lembert sutures above, and the same number below the tube. The sutures are cut short. Two similar parallel folds are again raised up and again stitched, and if necessary a third tier is added. A most efficient valve is thus formed. The stomach is fixed by one or two sutures to the anterior abdominal wall.
