Objective To analyze the relevant factors of portal vein thrombosis in patients after splenectomy for portal hypertension due to cirrhosis resulting from hepatitis. Methods The clinical data of 226 patients with hypertension due to cirrhosis resulting from hepatitis receiving simple splenectomy or splenectomy and portal-azygous devascularization in our hospital from August 2000 to June 2007 were retrospectively analyzed. Effective results were found in 154 of the patients. The 154 cases were divided into the thrombosis group and non-thrombosis group. The relation of portal vein thrombosis to the descendent level of portal vein pressure after operation,the prothrombin ratio (PTR) and fibrinogen(FIB) before operation, platelet count before and 1, 7, 14 days after operation, diameter of main portal vein and bilirubin level before operation and blood loss in operation were determined by logistic regression analysis. Results Portal vein thrombosis occurred in 31 patients. Regression univariate analysis showed that portal vein thrombosis was related to the descendent level of portal vein pressure after operation but not to the PTR and FIB, platelet count, diameter of main portal vein, bilirubin level and blood loss. Multivariate analysis demonstrated the same results. Conclusion The descended level of portal vein pressure is an important factor in portal vein thrombosis in patients after splenectomy for portal hypertension due to cirrhosis resulting from hepatitis.

Objective To investigate the reasons of complications after ultrasound-guided PTBD and explore measures for their management. Methods The clinical data of 753 patients with obstructive jaundice treated with ultrasound-guided PTBD in our hospital from January 2001 to June 2008were retrospectively analyzed. Results The 753 patients received a total of 791 treatments of PTBD.The occurring rates of severe, common, and long-term complications were 1.14 % (9/791), 11.88 %(94/791 ) and 4.3% (9/791), respectively. Only 1 patient died of manipulation-related complications.Conclusion Ultrasound-guided PTBD is an effective method for treatment of obstructive jaundice.

Objective To study clinical value of percutaneous intrabiliary expandable metallic biliary stenting (EMBS) for treatment of malignant obstructive jaundice. Methods One hundred and sixty patients with malignant obstructive jaundice were treated with EMBS ( EMBS group) . Thirty patients underwent only external drainage by PTCD were recruited as control. The patency rate of stent,decline of bilirubin and the complication were analyzed retrospectively. Both groups were followed up for three months. The Kaplan-Meier method (log-rank test) was used to compare the survival period between the two groups. Results Anorexia,skin pruritus and color of urine alleviated at a certain degree in both groups.In the EMBS group,plasma total bilirubin was(218. 78 ±2. 29) μmol/L pre-stent,and decreased to (134. 90 ±2. 34), (83. 18 ±2.40) , (40. 74 ±2. 29) μmol/L at the 7,14,21 days after the stenting, respectively; direct bilirubin was (128.82 ±2.40) μmol/L pre-stent, and decreased to (81.28 ± 2. 34), (51. 29 ±2. 45) and (25. 70 ±2.40)μmol/L at the 7,14,21 days after the stenting ( P =0. 000). In the PTCD group,plasma total bilirubin was (223. 57 ± 2. 58) μmol/L pe-stent, and decreased to ( 145. 68 ± 2. 57 ) ,(87.57 ±2.58) ,(38.65 ±2. 20) μmol/L at the 7,14,21 days after the stenting,respectively;direct bilirubin was (127. 6 ±2. 59)μmol/L pre-stent,and decreased to (79. 78 ±2. 70) ,(58. 36 ±2. 46) and (29.46 ±2. 20)μmol/L at the 7,14,21 days after the stenting,respectively ( P <0.001 ). No significant difference was found between the two groups at any time point ( P > 0. 05). Complications occurred in 34 patients in the EMBS group and the incidence rate was 20. 62% . Two or more complications occurred in 9 patients. In the PTCD group, complications occurred in 60.00% of the patients. In the EMBS group, 14 patients were failed to follow up, and 136 died. The median length was 214 days. In the PTCD group,all patients were followed up and all died,with a median length of survival of 75. 5 days. The survival analysis showed that the EMBS group survived longer than the PTCD group (P =0. 000). Conclusions EMBS placement showed better effect than PTCD. Compared to PTCD, internal drainage of metallic stents lead few complications and faster recover, and can improve the life quality and prolong survival time of patient with malignant obstructive jaundice. The placement of metallic stents is recommended as a preference for palliative therapy of malignant biliary obstruction.

Peliosis hepatis is a rare benign hepatic vascular disease.There is the lack of specific clinical features and preoperative diagnosis.A patient with intermittent liver area pain was admitted to the Third Central Hospital of Tianjin in April 2014.The patient with space-occupying lessions of the right lobe of liver was preliminarily diagnosed as with hepatocellular tumor or vasogenic tumor by computed tomography and B ultrasound examinations and then received liver resection combined with cholecystectomy.The result of postoperative pathological examination confirmed peliosis hepatis with adenomatous hyperplasia of liver cells.The patient was followed up till October 20,2014 without recurrence.

Objective To analyze relevant factors causing pancreatic fistula post pancreaticoduodenectomy with ex-ternal drainage of pancreatic duct. Methods Altogether 133 patients who underwent pancreaticoduodenectomy with exter-nal drainage of pancreatic duct in our hospital from 1999 to 2011 were retrospectively analyzed. Logistic regression analysis was used to analyze the relevance of pancreatic fistula with age, gender, combined diseases, pancreatic duct diameter, patho-logical types, preoperative total bilirubin (TBIL), albumin (ALB) levels, drainage of the bile duct before operation, obstruc-tion of the pancreatic duct drainage and postoperative application of growth somatostatin. Then we also analyzed the relation-ship between those risk factors and the severity of pancreatic fistula. Results Postoperative pancreatic fistula occurred in 24 cases (3 cases were of grade A,13 cases were of grade B and 8 cases were of grade C) among the 133 patients. Logistic re-gression analysis showed that obstruction of the pancreatic duct drainage is a major risk factor of pancreatic fistula in these patients(OR=4.529,P=0.005). The patients whose pancreatic duct drainage was obstructed had a significantly higher pan-creatic fistula rate than the patients whose drainage was not obstructed (30.8%vs 12.8%, P＜0.05). The occurrence of pan-creatic fistula has no significant correlation with age, gender, combined diseases, pancreatic duct diameter, pathological types, preoperative TBIL, ALB level, preoperative bile duct drainage and postoperative application of somatostatin. What’s more, in those pancreatic fistula patients, the pancreatic fistulas were more severe in the obstructed ones than those in the un-obstructed ones. Conclusion The obstruction of the pancreatic duct drainage is a major risk factor of pancreatic fistula post pancreaticoduodenectomy with external drainage of pancreatic duct. If adequate preventive measures were employed during operation , the incidence of pancreatic fistula and pancreatic fistula severity will be significantly reduced.

Objective To observe the influence of peripheral serum came from patients with hepatectomy at different time points on hepatocyte proliferation in vitro. Methods According to the different types of cultured serum, cultured HL-7702 cells were divided into fetal bovine serum (FBS) group, preoperative serum group, 0.5 h, 3 h, 24 h and 72 h post operative serum groups. All groups of cells were cultured for 72 hours in the Cell-IQ unmarked living cell image analysis system, and the amplification curves of each group were mapped by continuous counting of cells. The cell amplification multiple was compared between all groups after culturing for 72 hours. BrdU immunofluorescence staining was performed and BrdU positive rate was calculated for comparing the cell proliferation of all groups. Results Amplification curves showed that HL-7702 cell proliferation rates of all human serum groups except for 72 h post operative group were higher than those of FBS group. Human serum 0.5 h and 3 h postoperative groups were more obvious. The amplification multiples of human serum groups, except for 72 h post operative group were all significantly higher than those of FBS group (P<0.01), and 0.5 h and 3 h post operative groups were both significantly higher than those of preoperative group (P < 0.05). BrdU positive rates of all human serum groups were significantly higher than those of FBS group (P < 0.01), which were significantly higher in 0.5 h and 3 h post operative groups than those of preoperative group (P < 0.05), but there were no statistical differences between 24 h and 72 h post operative groups and the preoperative group. Conclusion Human serum can promote the proliferation of hepatocytes compared with that of FBS. The influence of serum acquired post hepatectomy is closely associated with the post operative time.

Objective To investigate the common complications of thermal ablations of liver cancer using both radiofrequency ablation (RFA) and microwave ablation (MWA) techniques,and compare the safety between these two procedures.Methods A total of 879 patients with hepatic tumors underwent thermal ablation.There were 323 cases having the RFA procedures and 556 cases having MWA procedures.The complications of thermal ablations of liver cancer were compared using both RFA and MWA techniques.Results A total of 1030 thermal ablation sessions was performed in 879 patients with a total of 1652 tumors.There were 323 patients with 562 tumors received a total of 376 RFA.The other 556 patients with 1090 tumors received a total of 654 MWA.The mortality rates were 0.31 ％ (1/323) and 0.36％ (2/556) in RFA and MWA group.In RFA and MWA group,the major complication rates were 3.5％ (13/376)and 3.1％ (20/654),meanwhile the minor complication rates were 5.9％ (22/376) and 5.7％ (37/654).There was no statistical significant difference for the mortality rates,the major complications,the minor complications between the RFA and MWA groups (P ＞0.05).Conclusions Thermal ablation therapy in the treatment of liver cancers is relatively safe with low mortality and low incidence of serious complications.The types and incidences of complications caused by RFA and MWA are similar and comparable for safety consideration in clinical settings.

Objective To investigate the levels of serum Golgi protein(GP73) (sGP73) in patients with HBV-related liver disease and investigate the role of sGP73 as an indicator for diagnosis of hepatocelluar carcinoma (HCC).Methods The concentration of sGP73 in patients with chronic hepatitis B (CHB,n =31),liver cirrhosis (LC,n =60),HCC (n =71),self-limited HBV infectors (n=21 ) and healthy controls (n =42) were tested by enzyme-linked immunosorbent assay (ELISA) assay and statistically analyzed in combination with relevant clinical indicators.Results The median of sGP73 in HBV-related liver disease group was significantly higher than that in the groups of self-limited HBV infectors and healthy controls respectively (P＜0.01).Among the groups with HBV-related liver disease,the median of sGP73 in LC group (231.13 ng/ml) was significantly higher than that in HCC without treatment group ( 117.63 ng/ml) (P ＜ 0.01 ) and CHB group (93.09 ng/ml) (P＜0.01).No significant difference was shown between HCC (without treatment) group and CHB group (P＞ 0.05),neither between self limited HBV infectors and healthy controls (respectively,36.79 ng/ml and 45.40 ng/ml) (P ＞ 0.05). The median of sGP73 in post-operation group (175.12 ng/ml,n=52) was significantly higher than in pre-operation HCC group (107.28 ng/ml,n=52) (P＜0.01).Along with the decreasing of liver function,sGP73 level was elevated in groups with HCC or LC.The receiver operating curve (ROC) constructed with the ratio of AFP and GP73 (AFP/GP73) showed a sensitivity of 78.87 ％ and specificity of 86.21 ％ with an area under the receiver operating curve (AUROC) of 0.878 (95％ CI:0.817-0.938) for diagnosis of HCC; comparably,a sensitivity of 67.61％ and specificity of 85.12％ were shown with a AUROC of 0.826 (95％ CI:0.755-0.897) when performed with AFP.Conclusion The level of sGP73 in HBV-related liver disease group is higher than that in the groups of self-limited HBV infector and healthy control,and it is positively correlated with the degree of hepatic impairment.For the diagnosis of HCC,joint detection of AFP and GP73 could achieve a better combination of sensitivity and specificity than the independent AFP test.
