Prognostic factors in surgery for duodenal XXXX .

@entity1 @entity1066 @entity86 @entity432 @entity7623
A 5 to 12 year follow-up study of 132 @entity1 with nonobstructive duodenal @entity1066 treated by HSV without a drainage procedure was done. The results of pre- and postoperative gastric emptying studies and pre- and postoperative acid secretion studies were related to recurrent @entity86 . The almost 9 percent of instances of recurrent ulceration were found in the group of @entity1 with preoperative PPAO values greater than 40 mmol/hr. In all 13 @entity1 with preoperative PPAO values greater than 60 mmol/hr, HSV was considered a failure. It was concluded that at least the latter group should be excluded from HSV. In 4.3 percent of @entity1 serious @entity7623 after HSV was cause for reoperation. In spite of meticulous denervation and peroperative open pH metry, inadequate vagotomy, defined as percent reduction of PIAO values after HSV less than 75 percent, was found in 33 out of 117 @entity1 . In an experimental study, @entity432 alone also gives a positive Grassi test. From both facts the relative value of this test can be concluded. Symptoms after inadequate vagotomy were again clearly related to preoperative PPAO values.
