[Changes in gut hormones after Roux-en-Y cholangio-jejunostomy].
In order to explore the mechanism of secondary gastric acid hypersecretion after Roux-en-Y Cholangio-jejunostomy (CJR-Y), we studied the changes of gastric acid secretion and determined the levels of somatostatin (SS), gastrin (Gn), neurotensin (NT), beta-endorphin (beta-EP) in serum, gastric juice and pyloric antrum in patients with CJR-Y. The results showed that gastric hypersecretion developed, levels of SS in those specimens decreased significantly and the content of Gn increased obviously after CJR-Y; whereas the content of NT and beta-EP did not change significantly. We concluded that the decreased level of SS plays a role in the mechanism.
