Abstract:
Objective To investigate the dysfunction of gallbladder emptying in diabetic patients and its possible mechanism. Methods The postprandial gallbladder emptying function and the release of pancreatic polypeptide (PP), as well as the therapeutic effect of Cisapride on gallbladder contraction were observed in 50 diabetics without cholecystolithiasis and 15 normal controls. The distributions of nitric oxide synthase (NOS) and acetylcholinesterase (AChE) in the wall of surgical removal gallbladders of 7 diabetic patients with cholecystolithiasis were also studied by histochemistry method. Results (1) The function of gallbladder emptying was distinctly lower in diabetic patients with autonomic neuropathy (AN) than that of the healthy subjects and diabetic patients without AN (NAN). (2) The postprandial release of PP in AN group was significantly lower than those in NAN group and healthy subjects. (3) The gallbladder emptying function was improved after receiving Cisapride in patients with AN. (4) Both the amount and activity of NOS and AChE in the wall of gallbladders of diabetic patients were lower than that of the non-diabetic subjects. Conclusion The dysfunction of gallbladder emptying in diabetic patients is partly due to the impaired autonomic nerve. The administration of Cisapride will improve the gallbladder emptying function of diabetic patients with AN.
