Partial splenic embolization using polyvinyl alcohol and gelfoam to treat hypersplenism in cirrhotic patients: a Meta-analysis / 中华肝胆外科杂志

Objective To evaluate the effectiveness and safety of partial splenic embolization using polyvinyl alcohol versus gelfoam to treat hypersplenism in cirrhotic patients.Methods A literature search was performed in databases which included PubMed,Embase,Cochrane library,Sinomed,CNKI,Wangfang data and VIP for trials on partial splenic embolism using PVA or gelfoam to treat hypersplenism in cirrhotic patients.The study was censored in May 2016.After data extraction and assessment of quality,a meta-analysis was performed using the RevMan 5.3 software.Results Five studies which involved 197 patients were selected in this study.Included into the PVA group were 92 patients and the gelfoam group 105 patients.On Meta-analysis,the PVA group had a higher value of WBC a month after PSE (WMD =0.4,95％ CI:0.05 ～ 0.75,P ＜ 0.05),higher values of WBC (WMD =0.39,95％ CI:0.06 ～ 0.71,P ＜0.05) and PLT (WMD =8.08,95％ CI:1.65 ～ 14.51,P ＜ 0.05) on month 6 post-embolization.The degree of post-embolization pain was more severe (RR =1.32,95％ CI:1.14 ～ 1.54,P ＜ 0.05) and the length of painful time was longer (RR =2.01,95％ CI:1.36 ～ 2.66,P ＜0.05) in the PVA group.There were no significant differences in the values of PLT,fever and complications (all P ＞ 0.05).Conclusions PSE using PVA achieved better short-term and long-term results in hematological indicators than gelfoam.However,the degree and extent of duration of pain were significantly longer.

Independent research and development of hepatitis B five internal quality control products by the detection of ELISA / 国际检验医学杂志

Objective To use ELISA detecting self‐developed hepatitis B five internal quality control products .Methods Hepa‐titis B five positive sera by the detection of ELISA were diluted through optimal ratio ,and were homemade indoor quality control materials .Results Self‐control materials and commodities were simultaneously detected by ELISA ,and the test results were com‐pared ,the two were no significant difference(P>0 .05);Self‐control materials continuously detected by ELISA ,its batch variation were less than 15% ,and stability was in line with the requirements .Conclusion Self‐developed hepatitis B five indoor quality con‐trol materials are made simply ,have good stability ,are satisfied control effect ,and have promotional value .

Laparoscopic ultrasound to exclude cystic duct obstruction in laparoscopic subtotal cholecystectomy / 中华肝胆外科杂志

Objective To investigate the use of laparoscopic ultrasound to exclude cystic duct obstruction and its related risk factors in laparoscopic cholecystectomy.Methods The data of 28 patients who underwent laparoscopic cholecystectomy in our department for cystic duct obstruction from February 2008 to April 2010 were analyzed.Subtotal resection of gallbladder and exclusion of cysticduct were carried out when the gallbladder triangle anatomy was not clear.An abdominal drain was used.Results All the patients were cured and there was no bleeding,abdominal infection,or jaundice.On univariate analysis,risk factors for cystic duct obstruction were adhesions in Calot triangle,gallbladder atrophy,acute cholecystitis,cystic duct stone incarceration,gallbladder wall thickening and white bile.Adhesion in Calot triangle,acute cholecystitis and white bile were independent risk factors on multivariate analysis.Conclusion Excluding cystic duct obstruction by laparoscopic ultrasound for patients who underwent laparoscopic cholecystectomy for cystic duct obstruction is safe and effective.

Diagnosis and treatment of early-stage hepatic artery complications after orthotopic liver transplantation / 中华肝胆外科杂志

ObjectiveTo determine the risk factors and the optimal management of hepatic artery complications (HAC) after orthotopic liver transplantation.MethodsThe clinical data of 180 orthotopic liver transplantation patients performed between January 2005 and September 2007 was reviewed.The incidence of HAC between primary liver carcinoma and benign diseases of liver was compared.ResultsTwelve (6.7％) episodes of HAC were identified.3 were hepatic artery thrombosis (HAT) and 9 were hepatic artery stenosis (HAS).The incidence of HAC in patients with primary liver carcinoma (6/39) was higher than benign disease (6/141)(P＜0.05).ConclusionsThe keys to management of HAC after orthotopic liver transplantation are to diagnose the complication in time and to select the proper treatment based on the type of HAC.

Liver retransplantation, clinical analysis of 6 cases / 中国普通外科杂志

Objective To explore causes leading to and the timing of liver retransplantation. Methods Among 164 cases of liver transplantation from Jul. 1999 to Dec. 2004, 6 cases underwent retransplantation with an incidence of 3. 65%. Causes included multiple intrahepatic bile duct stricture by ischemic reperfusion injury in 3 cases, hepatic artery stricture and thrombosis, hepatitis B recurrence, outflow obstruction of hepatic veins in one each. Results Clinical symptom improved in 4 cases, and failed to improve in 2 cases. Two cases suffered from intraabdominal bleeding, one biliary leak, one bacterial infection, two mold infection. Two patients died from bacterial and mold infection in four months. Conclusion Ischemic reperfusion injury is main cause resulting in intrahepatic bile duct stricture, liver retransplantation should be performed when the function of graft deteriorates significantly and conservative therapy fails.
