Objective To investigate the clinical characteristics, pathological features and surgical indications of polypoid lesions of the gallbladder (PLG). Methods The clinical data of 267 patients with PLG confirmed by pathological examination were analyzed retrospectively. Results PLG was found more frequently in young and middle-aged people. Of the 267 patients, 166 were male and 101female. There were 241 cases with cholesterol polyps(CPs) (90. 3%). CPs were the most common PLG, but they presented no special clinical features. Conclusion CPs are dominant in PLG. Patients older than 60 years with a single polyp lesion or gallbladder stone complications should resort to surgical treatment. Patients with no symptoms and PLG of less than 10mm should be followed up periodically. Cholecystectomy for PLG should be performed based on strict indications of PLG.

Objective To study the clinical effects of the intensive insulin therapy on diabetes with acute obstructive suppurative cholangitis in elderly patients.Methods Sixty-four patients aged over 70 were divided into two groups:group A(maintenance of blood glucose at a level between 4.4 and 6.1lmmol/L)and group B(maintenance of blood glucose at a level between 10.0 and 11.1mmol/L).Insulin was infused by micro-injection pump.The changes of APACHEII score postoperative complications,average length of stay in hospital and prognosis were observed.Results The average APACHEII score of group A was significantly decreased after 3rd day postoperation(P＜0.01).The average length of stay in hospital of group A was significantly shorter than that of group B(P＜0.05).The postoperative complications of group A were significantly decreased(P＜0.05).Conclusion Intensive insulin therapy contributes to the outcome of the elderly patients with acute obstructive suppurative cholangitis.
