ABSTRACT
Esophagogastric variceal bleeding (EGVB) is one of the main complications of decompensated portal hypertension, especially in patients with liver cirrhosis, and it often has a high mortality rate. Medication combined with endoscopy is the main prevention and treatment method for EGVB, while transjugular intrahepatic portosystemic shunt (TIPS) combined with variceal embolization can also be selected for some high-risk patients, and individualized diagnosis and treatment of portal hypertension based on hepatic venous pressure gradient should become the latest consensus and the main strategy. This article mainly reviews endoscopic therapy and TIPS for the prevention and treatment of EGVB patients with decompensated portal hypertension in terms of selection of indications, incidence rate of complications, and respective advantages and disadvantages.
ABSTRACT
Objective:To investigate the clinical efficacy and prognosis of transjugular intrahepatic portosystemic shunt (TIPS) and drug combined with endoscopic treatment in patients with liver cirrhosis and esophagogastric variceal bleeding (EGVB).Methods:From January 2012 to December 2013, at the First Affiliated Hospital of Xi′an Jiaotong University, the data of 147 patients with liver cirrhosis and EGVB undergoing TIPS or drug combined with endoscopic treatment were retrospectively collected, with 87 cases in TIPS treatment group and 60 in drug combined with endoscopic treatment group.The 5 years follow-up data were analyzed, and the overall survival rates, rebleeding-free survival rates and hepatic encephalopathy-free survival rates at 6 weeks, 1 year, 2 years and 5 years after treatment of two groups were compared. Independent sample t test, Mann-Whitney U test, chi-square test, Fisher exact test, Z test, log-rank test and trend test were used for statistical analysis. Results:There were no significant differences in age, gender, etiology, Child-Pugh classification, initial liver function, coagulation function, liver ascites, previous history of hepatic encephalopathy, blood pressure and preoperative blood transfusion history between the TIPS treatment group and combination of drugs and endoscopy treatment group (all P>0.05). Forty-one patients died within 5 years, of which 20 (48.8%) died of rebleeding and 6 (14.6%) died of hepatic encephalopathy. There were no significant differences in 6-week, 1-year and 2-year overall survival rates between the TIPS group and drug combined with endoscopic treatment group (all P>0.05), however the 5-year overall survival rate of the TIPS treatment group was higher than that of the drug combined with endoscopic treatment group (78.4% vs. 63.2%), and the difference was statistically significant ( Z=2.06, P=0.048). The 6-week, 1-year, 2-year, 5-year rebleeding-free survival rates of the TIPS group were 97.7%, 96.5%, 88.9% and 70.9%, respectively, which were all higher than those of the drug combined with endoscopic treatment group (86.7%, 53.3%, 43.3% and 27.1%), and the differences were statistically significant ( Z=2.35, 6.39, 6.26 and 4.80, all P<0.05). There were no significant differences in hepatic encephalopathy-free survival rates at 6 weeks, 1 year and 2 years after treatment between the TIPS group and drug combined with endoscopic treatment group (all P>0.05), however the 5-year hepatic encephalopathy-free survival rate of the TIPS treatment group was lower than that of the drug combined with endoscopic treatment group (67.7% vs. 86.7%), and the difference was statistically significant ( Z=2.28, P=0.030). The lower the Child-Pugh classification, the higher the cumulative 5-year survival rate ( χ2=6.75, P<0.01). There was no statistically significant difference in the 5-year overall survival rate in patients with the same Child-Pugh classification between the TIPS group and the drug combined with endoscopic treatment group (all P>0.05). Conclusions:The efficacy of TIPS is better than that of the drug combined with endoscopic treatment in treating EGVB. Even the long-term risk of hepatic encephalopathy of TIPS is higher, the short-term, middle-term and long-term rebleeding rate are decreased. Patients with Child-Pugh grade C do not need to avoid TIPS when choosing the treatment, the earlier the TIPS used, the better survival benefit will be obtained.
ABSTRACT
Objective:To investigate the features of common bile duct adenoma under endoscopic ultrasonography (EUS).Methods:Clinical data of 15 patients with common bile duct adenomas confirmed by pathology from January 2015 to January 2020 in Tianjin Nankai Hospital were analyzed retrospectively. The patients′ EUS features were summarized.Results:The common bile duct adenoma was characterized by homogeneous soft tissue mass with medium or low echo and clear boundary, floating in the bile duct with no movement under EUS. EUS diagnosis of 14 out of 15 patients was consitent with the pathology, and the diagnostic consistency was 93.3%. One patient with a movable lesion was misdiagnosed as cholestasis by EUS. One patient had two solitary adenomas, located in the middle and lower part of the common bile duct, and 14 others had single adenoma. There were 9 adenomas in the lower part, 4 in the ampulla, 2 in the upper part, and 1 in the middle of the common bile duct. The pathological findings were 7 cases of villous adenoma with high-grade intraepithelial neoplasia, 4 cases of local malignant changes; 6 villous tubular adenoma with high-grade intraepithelial neoplasia, 3 local malignant changes; 2 villous tubular adenoma with low-grade intraepithelial neoplasia; and 1 papillary adenoma.Conclusion:EUS, helpful for the qualitative diagnosis, can be used as an important technique to improve the diagnosis of common bile duct adenoma.
ABSTRACT
Objective To investigate the clinical characteristics of incarcerated stones at duodenal papilla and to evaluate the efficacy of endoscopic needle-knife sphincterotomy ( NKS ) . Methods Data of 316 patients who underwent endoscopic treatment for incarcerated stones at duodenal papilla between 2007 and 2016 were retrospectively studied. Endoscopic treatment outcomes, proportion changes of incarcerated stones in total number of choledocholithiasis, changes of diameter of common bile duct( CBD) and diameter of incarcerated stones were analyzed. Results Obstruction was relieved and endoscopic nasobiliary drainage was successfully performed in all 316 cases ( 100. 0％) , and NKS procedures were performed in 231 patients ( 73. 1％) . The incidence of incarcerated stone at duodenal papilla in choledocholithiasis showed a decreased trend ( P=0. 000) . Diameters of both CBD and incarcerated stones showed a decreased trend in hierarchical data by year ( P=0. 000, P=0. 000) . Conclusion The incidence of incarcerated stones at duodenal papilla in choledocholithiasis, the diameters of CBD and incarcerated stones are all on the decrease. NKS is the primary method for treatment of incarcerated stones at duodenal papilla.

ABSTRACT
Objective To evaluate the application value of emergency endoscopic needle-knife sphincterotomy(NKS) on acute cholangitis of severe type (ACST) resulting from impacted common bile duct stones at duodenal papilla. Methods A retrospective study was performed on the data of 90 ACST cases with impacted common bile duct stones at the native papilla and undergoing emergency NKS between January 2011 and January 2017 in Tianjin Nankai Hospital. The completion of treatment, mean operating time, impacted stone clearance rate, changes of laboratory indexes before and after endoscopic procedure, and complications were analyzed. Results All the 90 patients underwent emergency NKS successfully, with a total success rate of 100. 0％. The mean operating time was 25. 2±11. 7 min. The impacted stone clearance rate was 95. 6％(86/90). The complication rate was 5. 6％(5/90), including 3 cases of hemorrhage and 2 cases of post-ERCP pancreatitis. There was no procedure-related mortality. The postoperative white blood cell count, serum procalcitonin, total bilirubin, direct bilirubin, and glutamic-pyruvic transaminase decreased significantly compared with pre-operation ( all P<0. 001) . Conclusion Emergency NKS is effective and safe for treatment of ACST resulting from impacted common bile duct stones at duodenal papilla with a relative high application value.
ABSTRACT
Objective To compare the effects of different stent configurations on shunt failure,hepatic encephalopathy,and hepatic myelopathy after transjugular intrahepatic portosystemic shunt (TIPS).Methods From March 2014 to June 2015,the clinical data of 73 hospitalized,patients who met the inclusion and exclusion criteria,and underwent TIPS for upper gastrointestinal hemorrhage caused by cirrhotic portal hypertension were retrospectively analyzed.According to the stent configuration during operation,patients were divided into simple coated stent group (hepatic vein,portal vein and hepatic parenchyma coated stent,23 cases),simulated Viatorr stent group (hepatic vein and hepatic parenchyma coated stent plus portal vein bare stent,27 cases) and combined stent group (hepatic vein and portal vein hare stent plus hepatic parenchyma coated stent,23 cases).Patients were followed up for one year,the incidences of shunt failure,hepatic encephalopathy and hepatic myelopathy within one year after TIPS of three groups were compared.Chi-square test,Fisher exact probability method and variance analysis were performed for comparison among groups.Cox regression analysis was used for difference analysis in imbalance of variables and incidence of outcome events among the three groups.Results The portal vein pressure gradient of simple coated stent group,simulated Viatorr stent group and combined stent group decreased from (22.15±4.52),(23.01±5.48) and (21.13±4.49) mmHg (1 mmHg=0.133 kPa) to (9.15±2.94),(11.20±3.27) and (8.75+4.06) mmHg after operation,respectively.Before and after operation,the differences in portal venous pressure gradient were statistically significant of three groups (t=10.488,7.188 and 7.850,all P＜0.05).The shunt failure rates of simple coated stent group,simulated Viatorr stent group and combined stent group were 13.0％ (3/23),18.5％ (5/27) and 30.4％ (7/23),respectively.The results of Cox regression analysis indicated that there was no statistically significant difference in shunt failure rates among different stent configurations after TIPS (P=0.339).The incidences of hepatic encephalopathy of simple coated stent group,simulated Viatorr stent group and combined stent group postoperative were 69.6％ (16/23),33.3％ (9/27) and 30.4％ (7/23),respectively,the difference was not statistically significant among the three groups (P＞ 0.05).The results of Cox regression analysis showed that the relative ratio values (95％ confidence interval) of incidence of postoperative hepatic encephalopathy of simple coated stent group compared with simulated Viatorr stent group and combined stent group were 2.901 (1.279 to 6.584) and 2.735 (1.123 to 6.658),and the differences were statistically significant (both P＜0.05).The incidences of hepatic myelopathy of simple coated stent group,simulated Viatorr stent group and combined stent group were 8.7％ (2/23),3.7％ (1/27) and 4.3％ (1/23),respectively,and there was no statistically significant difference in the incidence of hepatic myelopathy among three groups after operation (P＞0.05).During one-year follow-up,among 73 patients,two patients died,one in simple coated stent group and the other in combined stent group.The one-year survival rate after TIPS was 97.3％.Conclusions One year after operation,the incidences of shunt failure are similar between simple coated stent group,simulated Viatorr stent group and combined stent group.One year after operation,the incidence of hepatic encephalopathy is similar between simulated Viatorr stent group and combined stent group which are both lower than that of simple coated stent.The incidence of hepatic myelopathy is low,and its association with TIPS remains to be further investigated.
ABSTRACT
Objective To explore the effect of puncture the left or right branch of portal vein on the incidence of postoperative hepatic encephalopathy in transjugular intrahepatic portosystemic shunt (TIPS). Methods A literature search was conducted through investigating PubMed, Cochrane Library, CNKI digital library and Wanfang databases. Randomized controlled trials and cohort studies related to the effect of puncture the left or right branch of portal vein on the incidence of postoperative hepatic encephalopathy in TIPS were included in this review. According to the methods for Cochrane systematic review, the data were extracted, the quality of the literatures was evaluated, statistical analysis was conducted and the data were analyzed with RevMan 5.0. Results One randomized controlled trial and four cohort studies, including 552 patients with liver cirrhosis received TIPS, were finally included in this review. Random-effects model meta-analysis showed that puncture of the left branch of portal vein in TIPS caused lower incidence of postoperative hepatic encephalopathy than puncture of the right branch of portal vein (RR=0.51, 95%CI was 0.39 to 0.66, P<0.01). Conclusion Puncture of the left branch of portal vein in TIPS can significantly reduce the incidence of postoperative hepatic encephalopathy in comparison with puncture of the right branch of portal vein.

ABSTRACT
Objective To study the effect and safety of endoscopic retrograde appendicitis therapy (ERAT) in treating patients with uncomplicated acute appendicitis. Methods Patients with uncomplicated acute appendicitis were enrolled and divided into ERAT group and LA group received laparoscopic appendectomy. Then compare treat-ment condition, complications and follow-up of the two groups. Results ERAT were completed successfully in all the patients in ERAT group, while one patient underwent a reversion to open appendectomy for technical difficulties in LA group. Mean operative time was (49.7 ± 18.2) min for ERAT group and (68.9 ± 25.9) min for LA group (P <0.05). Fever relief time (1.3 ± 0.5) d, WBC normalization time (2.0 ± 0.9) d, mean bed time (0.1 ± 0.2) d and mean hospital stay (3.3 ± 1.6) d for ERAT group were significantly lower than LA group (P <0.05). 14 patients with intra-luminal appendicoliths (7 of massive appendicoliths, 4 of broken appendicoliths and 3 of broken appendicoliths with luminal stenosis) underwent endoscopic lithotomy successfully in ERAT group, resulting in a success rate of 100.00%. One patient presented perforation after ERAT was cured with conservative treatment. During the follow-up of at least 1/2 year, the rate of recurrence was 10.00% in ERAT group. 1 patient (5.00%) underwent LA at the 5th month after ERAT during the follow-up. Conclusion ERAT is an effective and safe therapy in treating patients with uncomplicated acute appendicitis with advantages of minimal invasiveness and quick recovery. Uncomplicated acute appendicitis with appendicoliths and/or luminal stenosis are the most suitable indications for ERAT.
