[Intestino-esophageal reflux following gastrectomy. Mechanism of action and effectiveness of esophago-jejunoplication].

The influence of the type of reconstruction after gastrectomy upon the postoperative reflux was analyzed in 30 patients. The refluxed material could be directly gained by the long-term reflux aspiration test and, thus, the quality including bile acids could be evaluated. After esophago-jejunoplication and Roux en Y-derivation 5 out of 7 patients were asymptomatic; only one patient suffered from mild esophagitis. Total bile acid concentration was near to the test systems sensitivity. The result in 11 patients after esophago-jejunostomy without Y-en Roux, but with a preserved lower esophageal sphincter (LES) are similar to the former group, whereas in all cases of 12 patients in whom the LES was resected, severe reflux esophagitis and excessively elevated bile acid concentrations were present. These results confirm that a jejunoplication supports the antireflux effect of preserved parts of the LES. If--for oncologic reasons--the LES has to be resected, free intestinal-esophageal reflux is following. In these cases a Roux en Y-derivation is required.
