Objective To investigate the value of combined use of laparoscopic cholecystectomy(LC)and duodenoscopic procedures in the treatment of gallbladder stones with common bile duct stones.Methods We retrospectively analyzed clinical data of 164 cases of gallbladder stones with common bile duct stones treated with laparoscopic cholecystectomy + endoscopic sphincterotomy(EST)from January 2003 to December 2007.Results All the cases underwent ERCP and endoscopic sphincterotomy(EST)followed by LC.In the 164 cases,196 bile duct stones were extracted from 155cases with a success rate of 94.5%.The procedures were unsuccessful in 9 cases,and among them,4 cases had stricture of bile duct more than 2 cm in length,and 5 cases had impacted stones that precluded passage of the guide wire.After EST,6 of the 155 cases had the complication of mild acute pancreatitis and LC was performed after its treatment.The success rate of LC was 96.5% and the average hospital stay was(11?4)d.Conclusions The combined use of EST and ERCP before LC is effective in treatment of gallbladder stones with common bile duct stones,and has broadened the utilization of minimally invasive treatment for bile duct diseases.

Objective To identify risk factors associated with the severity of acute kidney injury (AKI) in-duced by crush syndrome and whether the patient required hemodialysis (HD). Method A retrospective study was designed. Within 19 days after the Chinese Wenchuan earthquake (May 12, 2008), 63 victims (33 men, 30women) of 2139 cases were hospitalized at Mianyang Central Hospital (Siehuau, China) because of crush syn-drome caused by crush injuries. The patients with renal dysfimcfion before the earthquake were excluded. Totally 63 patients with AKI associated with crush syndrome were included in this study and were divided into two groups: group 1, 25 patients, requiring HD (when urine volume <250 mL/d;serum potassium> 6 mmol/L) ; and group 2, 38 patients, without HD. The following data were collected retrospectively for all patients: (1) epidemiological parameters: age, gender, race, time under the rubble, liquid treatmem before being rescued; (2) clinical param-eters: blood pressure, body area crushed, amputation, fasciotomy, blood transfusion, quantity of fluid infusion, urine output in the first 24 hours; (3) initial laboratory data: complete blood count, urine analysis, serum chem-istry, arterial blood gas analysis. Comparisons between the two groups were made using SPSS 10.0. The quantita-tive data and categorical data were analyzed using t tests and χ2 tests, respectively. P -values < 0.05 were consid-ered to indicate significant differences. The significant variables were entered into logistic regression models to de-termine the risk factors for the severity of AK1 in patients with crush syndrome and whether the patient required HD. Results Four significant risk factors with P -values < 0.05 were identified: fasciotomy, cystatin C (Cys C)level, myoglobin (MB) level and lactic acidosis. The odds ratios (95% confidence intervals) were 8.641 (3.027～76.479), 6.956 (3.027～76.479), 5.379 (3.027～76.479) and 4.833 (2.569～32.764), respectively. Conclusions In addition to urine output and potassium levels, we found that four risk factors, namely faseiotomy, Cys C and MB levels, and lactic acidosis, were significanfly associated with the severity of AKI and whether the patient required hemodialysis.

Objective To validate the predictive value of hepatitis B virus ( HBV )-related hepatocellular carcinoma ( HCC) risk score model D2AS in chronic HBV infection patients without antiviral therapy.Methods A total of 93 patients with chronic HBV infection were selected between January 2015 and July 2017 in the Third Affiliated Hospital of Hebei Medical University.Clinical data including age , gender, medical history, ultrasonography, hepatitis B surface antigen ( HBsAg), hepatitis B surface antibody ( anti-HBs), hepatitis B e antigen ( HBeAg), hepatitis B e antibody ( anti-HBe), hepatitis B core antibody ( anti-HBc), HBV DNA and alanine aminotransferase levels were collected by information center .REACH-B score and D2AS score were used to predict the risk of HCC.Receiver operating characteristic curve (ROC) was used to evaluate the discrimination , and Hosmer-Lemeshow ( H-L) goodness-of-fit test was used to evaluate the calibration of the model.Results REACH-B score and D2 AS score for the 95 chronic HBV infection patients were 9 (8,12) and 0.95 (0.57,2.08), respectively.The area under the curve ( AUC) for REACH-B score and D2 AS score were 0.916 (95% confidence interval [ CI] 0.834-0.998) and 0.784 (95%CI 0.587-0.981), respectively.The difference was not statistically significant ( P ＝0.195).However, for HBeAg-negative patients with chronic HBV infection , the AUC for D2 AS score and REACH-B score were 0.952 (95%CI 0.876-1.000) and 0.913 (95%CI 0.821-1.000), respectively (P＝0.458).The H-L goodness-of-fit test was P＞0.05.Conclusions The D2 AS score can be used for HCC prediction among patients who do not meet antiviral criteria.The predictive value of the D 2AS score for HCC is comparable to the REACH-B score in HBeAg-negative patients with chronic HBV infection.

Objective: To explore the risk factors for prognosis in patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF), and to establish a prognostic model. Methods: A total of 193 patients diagnosed with HBV-ACLF who were admitted to the Department of Infectious Diseases of the Third Hospital of Hebei Medical University were collected from 1st January 2013 to 1st November 2018 as a derivation cohort. Thirty-five patients diagnosed with HBV-ACLF who were admitted to the Fifth Hospital of Shijiazhuang during the period from 1st July 2017 to 1st November 2018 were collected as a validation cohort. The survival condition of all patients at week 12 of admission was observed. The risk factors associated with short-term prognosis were analyzed by using multivariate logistic regression analysis, and a logistic regression equation prediction model was established and verified. The diagnostic performance of the prognostic model was evaluated using the receiver operating characteristic (ROC) curve, and was compared with model for end-stage liver disease (MELD) scoring system, Child-Turcotte-Pugh (CTP) scoring system, sequential organ failure assessment (SOFA) scoring system and chronic liver failure (CLIF)-SOFA scoring system. Results: Multivariate logistic regression analysis showed that age (odds ratio(OR)=2.133, 95% confidence interval(CI)1.033-4.405), total bilirubin (OR=3.371, 95%CI 1.610-7.060), serum creatinine (OR=4.448, 95%CI 1.697-11.661), hepatic encephalopathy (OR=5.313, 95%CI 2.463-11.461), and ascites (OR=2.959, 95%CI 1.410-6.210) were independent risk factors for predicting the short-term prognosis of patients with HBV-ACLF. The newly established logistic regression model (LRM)=-1.726+ 0.757×age+ 1.215×total bilirubin+ 1.049 2×serum creatinine+ 1.670×hepatic encephalopathy (with=1, without=0) + 1.085×ascites (with=1, without=0). The area under the ROC curve of the LRM for predicting the short-term prognosis of patients with HBV-ACLF was 0.82 (95%CI 0.76-0.88). Furthermore, the areas under the ROC curve of the models of MELD, CTP, SOFA, CLIF-SOFA were 0.67 (95%CI 0.60-0.75), 0.73 (95%CI 0.66-0.80), 0.77 (95%CI 0.70-0.83) and 0.72 (95%CI 0.65-0.80), respectively. The ROC-area under curve of the validation cohort was 0.81 (95%CI 0.65-0.97). Conclusions Age, total bilirubin, serum creatinine, hepatic encephalopathy, and ascites are independent risk factors for the prognosis of HBV-ACLF. The prognostic model established based on these factors can accurately predict the patients′ short-term prognosis, which is superior to MELD, CTP, SOFA and CLIF-SOFA.
