Brief Summary

Objective. To measure the pressures of the common bile duct in patients with and without cholelithiasis and relating them to the presence of pancreatobiliary reflux. Summary Background Data. The reflux of pancreatic enzymes into the epithelium of the bile duct and mainly of the gallbladder is an abnormal phenomenon that plays a role in the lithogenesis and carcinogenesis of this epithelium. It has been suggested that the cause of this reflux is the dysfunction of the sphincter of Oddi. Because the pressure of the common bile duct depends on the pressures of the sphincter of Oddi, this dysfunction would be reflected in an increase in the pressure of the common bile duct in patients with cholelithiasis. Methods. A prospective case-control study was designed. The universe was constituted by a convenience sample in which all patients undergoing gastrectomy for gastric cancer during 30 months in our institution were included. The primary outcome measure was to establish differences between common bile duct pressures in patients with and without cholelithiasis. Results. Common bile duct pressures in patients with gallstones showed a significant elevation (Mean 16.9 mmHg) compared to those of patients without gallstones (Mean 3.3 mm Hg) (p\<0.0001). These pressures correlated with the values of amylase and lipase in gallbladder bile; higher levels of these enzymes were found in patients with gallstones compared to patients without gallstones (p\<0.0001). Conclusions. Common bile duct pressures in patients with cholelithiasis were significantly elevated above the parameters previously considered normal.
