Objective To evaluate the value of endoscopy in etiological diagnosis and treatment of post - cholecystectomy syndrome. Methods Three hundred and twenty - six patients with post -cholecystectomy syndrome received ERCP. To reveral the etiology of post - cholecystectomy syndrome. For those with choledocholithiasis and those with papillary inflammatory stricture EST or EPBD were given those with papillary diverticulum and SOD EPBD were given, those with papillary tumor and hepatobiliary carcinoma EMBE were given and for those with bililary stricture in middle part of bile duct, purulent cholangitis, chloedocholithiasis(stones not excluded in one time)and bile leakage ENBD were used. Results ERCP was succeeded in 315 cases(96. 6%), 24 cases had no abnormal endoscopic findings view. 191 cases of choledocholithiasis 186 were totally get rid of stone after one to three times of opretion EST or EPBD was successfully given to 39 cases of 39 had papillary inflammatory stricture. Nine had papillary diverticulum which oppressed the papillary orifice, 7 had SOD, all of them were dealt with EPBD. Sixteen had stricture in the middle portion of bile duct, 11 of which were treated with ENBD. In 6 cases of papillary tumor and 5 hepatobiliary carcinoma patients jaundice improved significantly after received EMBE. Residual stones in cholecystic duct were seen in 4 cases. In 2 cases of bile leakage after cholecystectomy, ENBD was successfully carried out to avoid another operation. Complications were noted in 15 cases(4. 8%) of them. pancreatitis 11 cases, cholangitis 3 eases and hemorrhage of upper gastrointestinal tract one ease. Conclusion ERCP can find out the defenite cause of post - cholecystectomy syndrome at early stage and take corresponding endoscopic therapeutic measures. The complications of ERCP can be avoided by skillful operator.

Objective To improve the successful rate of endoscopic biliary drainage. Methods The experience of biliary drainage with duodenoscope for biliary obstruction from January 1998 to September 2001 was reviewed retrospectively. Endoscopic naso -biliary drainage (ENBD) , endoscopic retrograde biliary drainage (ERBD) and endoscopic metal biliary endoprothesis (EMBE) were performed in 242 cases, 43 cases and 35 cases respectively. Results Of 320 cases with biliary obstruction, 305 received successful drainage under endoscopy and 15 cases failed. Ten cases with ENBD failed but got successful drainage after modulating the site of naso-biliary tube or reinserting another tube. For 3 cases failed with ERBD, we chose plastic stents with appropriate length for 2 cases to achieve fluent drainage and percutaneous transhepatic biliary drainage (PTBD) was managed for another case after endoscopic management failed. For 2 cases with EMBE failed, one stent couldn' t exceed the tumor stricture site and one was obstructed by tumor implantion at one month after EMBE. Either a metal stent or a plastic stent was replaced through previous prothesis in these two failed cases. Conclusions The effect of endoscopic biliary drainage for biliary obstruction is definite. Mostly the drainage failure can be avoided as early as possible by analyzing the causes and taking some corresponding measures to correct it.

Cerenkov luminescence imaging ( CLI) , as an emerging molecular imaging method, has been extensively studied in tumor imaging, therapy monitoring and some other aspects. However, because of the weak penetration of Cerenkov radiation, CLI can not image the deep tissues. This review summarizes the modalities to overcome this problem.

ObjectiveTo assess whether intravenous contrast medium would result in acute kidney injury (AKI), and to determine the risk factors associated with contrast induced AKI (CI-AKI) and its outcome.Methods A retrospective observational study was conducted in intensive care unit (ICU) of Fuyang People's Hospital in Zhejiang Province from January 1st 2011 to December 31st 2014. All enrolled critically ill patients had accepted CT scan, and the hospital length of stay was longer than 48 hours, and the patients who needed renal replacement treatment were excluded. Patients were divided into contrast medium group and control group. AKI was defined according to Acute Kidney Injury Network (AKIN) criteria (serum creatinine content over 26.4μmol/L or 50% increase of it from baseline within 48 hours). The incidence of AKI was compared between the two groups, and risk factors for CI-AKI were determined by multiple logistic regression analysis. The relationship of CI-AKI and outcomes were also analyzed. Results A total of 2 370 critically ill patients were enrolled during the period. 474 (20.0%) of the 2 370 patients received contrast medium, and 70 of them suffered from CI-AKI (14.8%). In 1 896 patients who did not receive contrast medium, 235 of them suffered from AKI (12.4%). There was no significant difference in the incidence of AKI between two groups (χ2= 1.905,P = 0.168). After several confounding factors were adjusted, multiple logistic regression analysis showed that contrast medium was not found to associate with AKI in critically ill patients [odds ratio (OR) = 1.66, 95% confidence interval (95%CI) = 0.72-3.90,P = 0.201], and high acute physiology and chronic health evaluationⅡ (APACHEⅡ) score (OR = 1.70, 95%CI = 1.33-2.40,P< 0.001), sepsis (OR= 8.06, 95%CI =3.28-17.80,P< 0.001), shock (OR= 3.57, 95%CI = 1.73-8.01,P< 0.001) and use of nephrotoxic agent (OR= 1.96, 95%CI = 1.25-2.63,P = 0.015) were risk factors of CI-AKI. Ten of 70 patients with CI-AKI died (14.3%), and 21 out of 404 patients without CI-AKI, died (5.2%). There was no significant difference in the mortality rate (χ2= 8.060, P = 0.005). It was shown by multiple logistic regression analysis that age (OR=1.30, 95%CI = 1.05-1.71,P = 0.027), male sex (OR = 1.13, 95%CI = 1.05-1.20,P = 0.039), APACHEⅡscore (OR = 1.07, 95%CI = 1.03-1.18,P< 0.001), and sepsis (OR = 3.29, 95%CI = 1.92-6.46,P< 0.001) were highly associated with mortality of critically ill patients in whom contrast medium was used. However, the occurrence of CI-AKI showed no influence on the mortality rate (OR = 1.70, 95%CI = 0.88-3.56,P = 0.227).Conclusions The use of contrast medium is not a risk factor of CI-AKI in critically ill patients. CI-AKI will not raise mortality rate in ICU patients.
