Abstract
OBJECTIVES Three-dimensional magnetic resonance elastography (3D-MRE) allows for multiparametric modeling of both elastic and viscous tissue characteristics. Our aim was to compare 3D-MRE with conventional liver shear stiffness assessment in gauging obstructive jaundice (OJ), predicting the adequacy of biliary decompression after drainage, and discriminating OJ from liver fibrosis. METHODS Patients with no histories of liver disease (n = 201) were studied in retrospect, grouped by bilirubin levels as no jaundice (NJ ≤ 2 mg/dL; n = 75), mild OJ (>2 mg/dL and ≤ 4 mg/dL; n = 56), and severe OJ (> 4 mg/dL; n = 70). For comparison, another 75 patients with chronic hepatitis B and C infections and histologically proven liver fibrosis were similarly analyzed. Each patient underwent spin-echo echo-planar-imaging MRE at 60 Hz with 3D wave postprocessing. Logistic regression and ordinary regression models were used to compare the 3D-MRE model with liver shear stiffness. RESULTS Liver shear stiffness, loss modulus, and damping ratio were incorporated into a 3D-MRE model, which significantly outperformed shear stiffness in predicting OJ severity (accuracy: 0.801 vs 0.672; p < 0.001). Both the 3D-MRE model and liver shear stiffness performed equally well in predicting the outcome of biliary drainage procedure (C-statistics: 0.852 vs 0.847; p = 0.48). The 3D-MRE model also demonstrated significantly better C-statistics than that of liver shear stiffness in discriminating mild OJ from F1-F2 liver fibrosis (0.765 vs 0.641; p = 0.005) and severe OJ from F3-F4 liver fibrosis (0.750 vs 0.635; p = 0.031). CONCLUSIONS 3D-MRE is an innovative imaging method for gauging OJ severity, predicting the outcome of biliary drainage procedure, and discriminating OJ from liver fibrosis. KEY POINTS • 3D-MR elastography achieved promising results for predicting the severity of obstructive jaundice. • Advanced parameters of 3D-MR elastography demonstrated significantly better performance than that of shear stiffness of 2D-MR elastography in discriminating obstructive jaundice from liver fibrosis caused by chronic hepatitis B/C. • Both 3D-MR elastography and 2D-MR elastography were equivalent in predicting the outcome of biliary drainage procedure.

Abstract
Objective To evaluate the accuracy of percutaneous transhepatic biliary biopsy (PTBB) in patients with suspected biliary obstruction. Materials and methods This was a retrospective analysis of 18 patients with obstructive jaundice who underwent PTBB. In each patient, three to ten fragments were collected from the lesion. The final diagnosis was confirmed in the pathology report. We also reviewed analyses of the results of laboratory tests performed before the procedure, as well as the Bismuth classification, clinical outcome, complications occurring during the procedure, access route, and materials used. Results Technical success was achieved in 100% of the PTBB procedures. Among the 18 patients clinically diagnosed with bile duct stenosis, the pathological analysis confirmed that diagnosis in 17. In one case, the pathological findings were considered false-negative. The predominant tumor was cholangiocarcinoma (seen in 50% of the cases). Sixteen of the procedures (88.9%) were performed without complications. Transient hemobilia occurred in one case, and cholangitis occurred in another. Conclusion PTBB is a safe, viable, simple technique with a high rate of true-positive results for the definitive diagnosis of obstructive jaundice.

Abstract
Objective: To investigate the clinical effect of bile reinfusion combined with enteral nutrition support before surgery for hilar cholangiocarcinoma. Methods: A retrospective analysis of patients with hilar cholangiocarcinoma who underwent surgical treatment at Nanjing Drum Tower Hospital Hepato-biliary-pancreatic Surgery Department from July 2010 to August 2017 was completed.A total of 52 cases were finally enrolled in our study.All the patients included, on the basis of whether they received preoperative drainage and bile reinfusion, were divided into non-drainage group(n=15) and drainage group(n=37). Differences of clinical indicators, including operation time, intraoperative bleeding and serum liver function index levels at day 1, 3, 7 postoperative, postoperative complications(liver failure, biliary fistula, pleural effusion, peritoneal effusion, abdominal cavity infection, death in hospital), tumor classification, R0 resection, postoperative hospitalization time between the 2 groups were analyzed. At the same time, in the drainage group, patients were divided into non-enteral nutrition subgroup(n=13) and enteral nutrition subgroup(n=24) according to whether they received enteral nutrition before operation. The normal distribution data of the group was statistically analyzed by independent sample t test, the non-normal distribution data of the group was statistically analyzed by rank-sum test. The count data was statistically analyzed by non-calibration and correction of the square test. Results: There was no statistically significant difference in general infomation such as age, gender, and serum liver function between non-drainage group and drainage group(P>0.05). There was no statistically significant difference in general information such as age, gender, and serum liver function between non-enteral nutrition group and enteral nutrition group(P>0.05). The rate of vascular resection and reconstruction(33.3%) and operating time(10.8(2.2)h) in drainage group were both higher than those in non-drainage group(6.7% and 8.3(3.0)h), the differences were both statistically significant(χ(2)=4.397, Z=1.595; both P<0.05). The level of AST at the 7th day after surgery in drainage group(32.8(17.3)U/L) was significantly lower than that in non-drainage group(55.0(64.7)U/L), the difference was statistically significant(Z=-2.212, P<0.05). The level of TBil at 1st day after surgery in drainage group(43.6(91.2)μmol/L) was lower than that in non-drainage group(91.2(188.4)μmol/L), the difference was statistically significant(Z=-2.150, P<0.05). The rate of pancreatoduodenectomy(25.0%) and average operating time(11.1(1.3)h) in the enteral nutrition group were both higher than those in the non-enteral nutrition group(0, 9.0(2.6)h). The differences were both statistically significant(χ(2)=3.879, Z=-2.693; P<0.05). The average level of AST at the 1st day after surgery in enteral nutrition group(396.4(268.3)U/L) was significantly lower than that in non-enteral nutrition group(642.5(341.1)U/L), the difference was statistically significant(Z=-2.483, P<0.05). The average level of TBil at the 1st, 3th day after surgery in enteral nutrition group(38.8(21.5)μmol/L and 30.0(25.6)μmol/L) were both lower than those in non-enteral nutrition group(60.9(75.2)μmol/L and 46.5(50.0)μmol/L), the differences were both statistically significant(Z=-2.416, -2.026; P<0.05). The level of CRP at 1st, 3th day after surgery((41.9±31.1)mg/L, (50.8±31.4)mg/L)in enteral nutrition subgroup was lower than that in non-enteral nutrition subgroup((64.4±33.6)mg/L, (74.1±35.3)mg/L), the differences were both statistically significant(t=1.456, 1.675; P<0.05). Conclusion: Based on the present study , there is no effective improvement on postoperative recovery using bile reinfusion combined with nutrition support before R0 resection of hilar cholangiocarcinoma.

Abstract
Combined obstruction of the bile duct and duodenum is a common occurrence in periampullary malignancies. The obstruction of gastric outlet or duodenum can follow, occur simultaneously, or precede biliary obstruction. The prognosis in patients with combined obstruction is particularly poor. Therefore, minimally invasive palliation is preferred in these patients to avoid morbidity associated with surgery. Endoscopic palliation is preferred to surgical bypass due to similar efficacy, less morbidity, and shorter hospital stay. The success of endoscopic palliation depends on the type of bilioduodenal stenosis and the presence of previously placed duodenal metal stents. Biliary cannulation is difficult in type II bilioduodenal strictures where the duodenal stenosis is located at the level of the papilla. Consequentially, technical and clinical success is lower in these patients than in those with type I and III bilioduodenal strictures. However, in cases with failure of endoscopic retrograde cholangiopancreatography, with the introduction of endoscopic ultrasound for biliary drainage, the success of endoscopic bilioduodenal bypass is likely to increase further. The safety and efficacy of endoscopic ultrasound-guided drainage has been documented in multiple studies. With the development of dedicated accessories and standardization of drainage techniques, the role of endoscopic ultrasound is likely to expand further in cases with double obstruction.

Abstract
OBJECTIVE To compare the causes, clinical symptoms, laboratory test results, and prognosis in patients with acute liver failure (ALF) induced by traditional Chinese medicines (TCM) and by Western Medicines (WM). METHODS The medical histories of patients who were diagnosed with drug-induced ALF (DALF) (n = 96) after hospitalization in the 302 Military Hospital between January 2010 and December 2015 were retrospectively examined. RESULTS Fifty-eight of the 96 DALF patients (60.4%) had a hepatocellular pattern of DALF, 16 patients (16.7%) had a cholestatic pattern, and 22 patients (22.9%) had a mixed pattern. DALF resolved in 24 patients (25.0%). Twenty-five patients (26.0%) developed chronic liver injury, 43 patients (44.8%) died, and 4 patients (4.2%) underwent liver transplantation. There were 42 ALF patients (43.8%) who received WM, and 32 ALF patients (33.3%) who received TCM. TCM-induced ALF patients had a higher average age [42.4 ± 18.4) vs (33.5 ± 17.9) years, P = 0.04] and higher creatinine and urine nitrogen levels [(155.2 ± 108.8) vs (97.5 ± 130.4) mmol/L, P = 0.047; (9.1 ± 7.7) vs (4.3 ± 5.0) mmol/L, P = 0.002, respectively]. Patients with TCM-induced ALF exhibited an increased risk of renal injury [odds ratio (OR), 3.75; 95% confidence interval (CI), 1.330-10.577]. The 14 patients with TCM-induced ALF who died exhibited higher creatinine levels than the 18 patients with TCM-induced ALF patients who survived [(218.7 ± 111.6) vs (105.8 ± 78.4) mmol/L, P = 0.002]. They were also more likely to exhibit ascites (85.7% vs 44.4%, P = 0.017) and hepatorenal syndrome (78.6% vs 22.2%, P = 0.002). CONCLUSION TCM-induced ALF was more likely to be accompanied by renal injury than was WM-induced ALF, especially in TCM-induced ALF patients who died.
