[Operation for draining the stomach by subtotal pyloro-myectomy with and without dilatation of the mucous membrane (author's transl)].

According to our experiences a pyloroplasty adequate in shape and function can be formed by a separate plastic surgical treatment of the serosa muscularis and mucosa, which can not only be carried out in a very simple way, but if strict attention is paid to its indications and the technical details are adhered to exactly, it also guarantees a complete normalization of evacuation of the stomach without dumping syndrome and duodenal reflux with satisfactory reliability. The necessary intervention consists essentially of a subtotal pyloro-myectomy which is combined with distention of the canal mucous membrane if it is too narrow.
