[Enterogastric reflux following resecting and nonresecting stomach operations--a study with control of intragastric pressure].

The bilirubin content of the gastric juice was defined in 20 control persons and 60 patients after resecting and non-resecting gastric operations as a reflux indicator. It was correlated with the intragastric pressure. A reflux was demonstrable in 70% of the control persons. The bilirubin values were low in the control group and after selective proximal vagotomy without pyloroplasty, higher after selective proximal vagotomy with Finney's operation, antecolic Billroth II operation with enteroanastomosis by Baum and Billroth I operation, maximally after retro- and antecolic Billroth II operation. The intragastric function pressure values were higher in the control group, after vagotomy, and also after Billroth I operation than after Billroth II operation. A statistically certain correlation does not exist between the enterogastric reflux and the intragastric pressure.
