In an experimental study on 376 rats the ulcer risk was analyzed after Roux-Y-gastrojejunostomy resp. jejunal interposition. The following results were obtained: 5 to 10 months postoperatively stomal ulcers were found in up to 90%. The longer the jejunal segment, i.e. the lesser the reflux, the higher was the ulcer risk. ⋯ An additional vagotomy caused a reduction but not an elimination of the ulcer risk. We conclude from our results, that there is a protective role of the postresectional intestino-gastric reflux on the gastrojejunal anastomosis. A refluxpreventive procedure is therefore heavily ulcerprone.
