[Risk of ulcer following conversion operations of Billroth I stomachs in restorative reflux-preventing procedures--an animal experiment].
In an experimental study on 74 rats the ulcer risk was analyzed after Billroth-I-resection changed into secondary Roux-Y-gastro-jejunostomy resp. jejunal interposition. The following results were obtained: 1) 10 months postoperatively stomal ulcers were found in up to 75%. 2) The gastric pH was comparable with the control and significantly lower than after Billroth-I-resection. 3) 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 reflux-preventive procedure is therefore heavily ulcer-prone.
