Methods: A literature search of the MEDLINE/PubMed and Embase databases was conducted. All articles reporting the outcomes of TIPS creation for variceal bleeding and refractory ascites and hepatic hydrothorax in patients with HCC were included. Exclusion criteria were non-English language, sample size < 5, data not extractable, and data reported in another article. Results: A total of 280 patients (mean age, 48 – 58; male gender, 66%) from five articles were included. TIPS creation was performed for variceal bleeding in 79% and refractory ascites and/or hepatic hydrothorax in 26% of patients. Technical and clinical success was achieved in 99% and 64% of patients, respectively. Clinical failure occurred in 36% of patients due to rebleeding or recurrent bleeding (n = 77) or no resolution or improvement of refractory ascites and hepatic hydrothorax (n = 24). One percent of patient had major complications, including accelerated liver failure (n = 1) and multi-organ failure resulting from hemorrhagic shock (n = 1), all of which resulted in early (i.e., within 30 days) death. Hepatic encephalopathy occurred in 40% of patients after TIPS creation. Lung metastasis was found 1% of patient 5 months (n = 1) and 72 months (n = 1) after TIPS creation. Conclusion: TIPS creation seems to be safe and effective for the management of portal hypertension in patients with HCC.","PeriodicalId":32516,"journal":{"name":"Gastrointestinal Intervention","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47713101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The therapeutic basis for GI bleeding is endoscopic hemostasis. To date, epinephrine injection, through-the-scope clips, monopolar or biopolar coagulation, and band ligation have been established for GI bleeding. Despite the advances in endoscopic techniques, we often experience re-bleeding associated with significant in- hospital mortality in GI bleeding. New devices that complement the disadvantages of these conventional endoscopic techniques have recently been introduced. For example, over-the-scope clip, which has wider and stronger pressure than conventional mechanical devices, can ligate a wide range of surrounding mucous membranes and has been reported to be effective in severe lesions of fibrosis. In addition, hemostatic powders achieved successful hemostasis as primary or rescue therapy in several cases of GI bleeding. Successful application of these new techniques requires appropriate patient selection and understanding of the device and further research is expected in the future.

Of these complications, biliary strictures are regarded as an Achilles’ heel. Recently, treatment of anastomotic biliary stricture (ABS) has transitioned from conventional surgical revision to a nonsurgical treatment modality. Endoscopic serial balloon dilatation and/or multiple plastic stent replace- ments are highly effective and are now regarded as the first-line treatments. However, if the patient has undergone anastomosis by means of a hepaticojejunostomy, percutaneous treatment is performed. With recent technological advances and the rendezvous method, the clinical success rates of endoscopic and percutaneous ABS treatments have increased, but these methods fail in some patients who have total obstruction of anastomotic stricture. For these patients, magnetic compression anastomosis (MCA) has been suggested as an alternative method. Animal and human studies have demonstrated the safety and efficacy of MCA, and advancements in these nonsurgical methods have increased the clinical success rate of ABS. This review focuses on ABSs that develop after LT and discusses the clinical results of various nonsurgical methods and future directions.

Isayama","doi":"10.18528/GII180016","DOIUrl":"https://doi.org/10.18528/GII180016","url":null,"abstract":"Placement of a plastic or metal stent via endoscopic retrograde cholangiopancreatography (ERCP) currently serves as the first-line procedure for obstructive jaundice and acute cholangitis. Dysfunction of the biliary stent causes recurrence of symptoms and often requires reinterventions and hospitalizations. Therefore, duration of stent patency is commonly used as the primary endpoint in clinical studies of biliary stents. However, owing to considerable heterogeneity between studies in reporting of biliary stent patency, it has been difficult to compare and integrate results of indepen-dent studies. There has been between-study heterogeneity in definitions of stent patency, statistics reported for survival curves of stent patency, and methods to treat censored cases. In addition to stent occlusion, stent migration is a major cause of recurrent biliary obstruction after covered metal stent placement, which further complicates the reporting of stent patency. Reporting of functional success and adverse events has been also inconsis- tent between the studies. From the perspective of evidence-based medicine, the variations in the definitions of outcome variables potentially hinder robust meta-analyses. To overcome the issues due to the lack of outcome reporting guidelines on the topic, the TOKYO criteria 2014 for reporting outcomes associated with endoscopic transpapillary placement of biliary stents have been proposed. Due to their comprehensiveness, the TOKYO criteria can be readily utilized to evaluate various types of biliary stent placement using ERCP, irrespective of types of stents and location of biliary stricture. In this article, we review the TOKYO criteria as a standardized reporting system for endoscopically-placed biliary stents. We also discuss potential controversial issues in the application of the TOKYO criteria. Given that endoscopic ultrasound-guided biliary drainage is increasingly uti- lized for cases with failed ERCP or altered gastrointestinal anatomy, we further propose a potential application of the TOKYO criteria to reporting of outcomes of this procedure.","PeriodicalId":32516,"journal":{"name":"Gastrointestinal Intervention","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46662056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
