Abstract:
The aim of this study was to analyze the gallbladder motor function in chronic pancreatitis (CP) patients. Gallbladder emptying was evaluated in 11 patients, without and with addition of pancreatic extract and in ten controls. The results were compared and analyzed statistically. The ejection fraction (EF) of the gallbladder (GB) at 30, 45 and 60 minutes were calculated by using Tc-99m DISIDA scintigraphy. The EF of GB at 60 minutes was significantly higher in the controls when compared to patients, although the results between patients were similar without and with addition of pancreatic extract. The results suggest that the delay in the GB emptying does not depend on the eventual alteration in the intestinal phase of the vesicular stimulation, but it probably results from a mechanic factor, which depends on the chronic pathological process located in the head of the pancreas.
