Consensus conference on TIPS management: Techniques, indications, contraindications

Published:November 15, 2016DOI:https://doi.org/10.1016/j.dld.2016.10.011

      Abstract

      The trans jugular intrahepatic Porto systemic shunt (TIPS) is no longer viewed as a salvage therapy or a bridge to liver transplantation and is currently indicated for a number of conditions related to portal hypertension with positive results in survival. Moreover, the availability of self-expandable polytetrafluoroethylene (PTFE)-covered endoprostheses has dramatically improved the long-term patency of TIPS. However, since the last updated International guidelines have been published (year 2009) new evidence have come, which have open the field to new indications and solved areas of uncertainty. On this basis, the Italian Association of the Study of the Liver (AISF), the Italian College of Interventional Radiology—Italian Society of Medical Radiology (ICIR-SIRM), and the Italian Society of Anesthesia, Analgesia and Intensive Care (SIAARTI) promoted a Consensus Conference on TIPS. Under the auspices of the three scientific societies, the consensus process started with the review of the literature by a scientific board of experts and ended with a formal consensus meeting in Bergamo on June 4th and 5th, 2015. The final statements presented here were graded according to quality of evidence and strength of recommendations and were approved by an independent jury. By highlighting strengths and weaknesses of current indications to TIPS, the recommendations of AISF-ICIR-SIRM-SIAARTI may represent the starting point for further studies.

      Introduction

      Portal hypertension (PH) is one of the major complications of cirrhosis. The trans jugular intrahepatic porto systemic shunt (TIPS) has been an established procedure in the treatment of the complications of portal hypertension, including bleeding oesophageal varices, refractory ascites, hepatic hydrothorax, type-2 hepatorenal syndrome, and more recently, Budd–Chiari syndrome and veno-occlusive disease. However, despite these broad applications, many clinical aspects remain controversial. The multispecialistic contribute to patient selection and TIPS management have led the Italian hepatologic community to produce a consensus statements aimed to the reassessment of the technical and clinical aspects.

      Methods

      The goal of this document was to provide clinical guidelines for the proper management of TIPS. Promoter of this “Consensus Guidelines” was the Italian association for the Study of Liver (AISF). The Consensus was endorsed by: ICIR (Italian College of Interventional Radiology), SIRM (Italian Society of Medical Radiology) and SIAARTI (Italian Society of Anesthesia, Analgesia and Intensive Care).
      According to the PNLG (National Plan for GuideLines), the promoter identified a Scientific Board of Experts. The Scientific Board defined methodology, goals and acted as developer and reviewer.
      The methodology chosen involved the following steps:
      • 1.
        The Promoters and the Scientific Board selected the main topics of interest: 1. Technique, contraindications, and untoward effects of TIPS, 2. G.I bleeding, 3. Ascites, 4. Vascular disorders, 5. Liver transplantation, 6. Rare indications.
      • 2.
        For each topic a working party was identified by both the Promoters and the Scientific Board, and was composed by a group of at least four experts guided by a chairman. The chairman, together with the promoters and the Scientific Board, selected the relevant clinical questions aiming at focusing on the clinical practice and controversial areas. The questions were circulated within the working groups to refine the topics and to avoid duplications. The members of the working parties were identified on the basis of competence, role, expertise and publication/research in the field of end stage liver diseases and liver transplantation.
      • 3.
        Each working group independently carried out a systematic literature search and review, between October 2014 and May 2015, using Medline/Pub Med to support definitions and statements. Each recommendation was graded according with the Oxford grading system (Appendix 1 in Supplementary material).
      • 4.
        The working groups elaborated the proposed statements, graded according with the selected grading system. They prepared the statements together with the presentation of the literature review for each topic during phone conferences, group meetings and mailing exchange before the Consensus Conference (between February and May 2015).
      • 5.
        The jury members were nowhere involved in the selection, preparation and discussion of the topics and statements prior to the Consensus Conference.
      • 6.
        All the promoters, members of the Scientific board, working groups, and Jury invited to participate to the Consensus conference were asked to declare any potential conflict of interests.
      • 7.
        On June 4th and 5th, 2015 a Consensus Meeting was held in Bergamo. The consensus group consisted of a total of 102 participants (promoters, Scientific Board, Working Groups, and Jury). The jury was selected among Hepatologists, Radiologists, Surgeons, Methodologists, Intensive care physicians, epidemiologists, patient representatives and ethicists. During the first sessions the chairman of each group presented the selected topics and the proposed statements. A general discussion was held in order to refine the. At the end of the general session each group met independently to re-elaborate the final statements to be presented in the voting session according to the advices received by the jury. The final general session consisted in the presentation of the statement by the chairman of each working group, followed by a public vote from the jury. The agreement was reached if over 73% of the voters agreed upon a two-levels score (Agree, Disagree).
      • 8.
        The format of this document, drafted by the writing committee, includes the questions, the statements, the quality comments by the working group chairmen, the percentage of agreement of the jury and the selected references.

      Comment: Patients undergoing TIPS placement often present with critical conditions (liver dysfunction, large amount of ascites, recent haemorrhagic shock) with a mental status that can indeed influence the cooperation and the tolerance of the procedure. Moreover TIPS positioning can be an uncomfortable and prolonged procedure requiring analgesics and sedatives administration, which could facilitate the transition to (GA) with or without intention, and could precipitate adverse physiological responses in particularly frail patients [

      Comment: Relative technical contraindications are anatomical conditions associated with a reduction in technical success rate or with an increased risk of complications, such as liver tumours, the presence of multiple hepatic cysts. The clinical appropriateness of TIPS positioning should be evaluated on a case-by-case basis according with the relevance of the indication and the presence of general contraindications. Indeed, in the context of a life threatening condition such as acute variceal bleeding (with a trickier assessment of liver failure), a broader range can be adopted (Child C score <14).

      Comment: A specific evaluation of the bleeding risk in patients undergoing TIPS has never been reported. In cirrhotics, routine coagulation tests cannot define the coagulation status and the bleeding risk. Several observational and randomized placebo-controlled studies have shown that prothrombin time (PT) is a poor predictor of peri- or post-operative bleeding in patients with cirrhosis [

      SESSION 2: TIPS for portal hypertension complications: portal hypertension-related bleeding in cirrhotic patients

      The management of bleeding complications differs according to severity of the underlying liver disease and the stage of PH, ranging from primary prophylaxis of variceal bleeding to treatments aimed at controlling acute variceal bleeding or to prevent rebleeding. HVPG measurements in these settings has clearly been established as a clinically relevant diagnostic and prognostic tool [

      Comment: Variceal bleeding is unresponsive to initial combined pharmacological and endoscopic treatments in 10–20% of cirrhotic patients.

      SESSION 3: TIPS for portal hypertension complications

      3.1. Is TIPS more effective than conservative/medical treatment (large volume paracentesis plus albumin infusion±diuretics) to treat refractory ascites (defined according the International Club of Ascites criteria) or recidivant ascites (3 episodes of tense ascites in 1year)?
      Tabled 1
      Statement 3.1
      3.1a. TIPS is more effective than conservative/medical treatment to resolve refractory/recidivant ascites, greatly reducing the need of paracentesis (1a, A).
      3.1b. TIPS should be considered in all patients with refractory/recidivant ascites (1a, A).
      3.1c. In selected patients with refractory/recidivant ascites and without general contraindications (*) TIPS improves transplant-free survival (1a, A).
      3.1d. In patients who are eligible for liver transplant, TIPS should be planned in agreement with a Transplant Centre (5,D).
      3.1e. At present, in patients with ascites “early TIPS” is not indicated. The concept of “early TIPS” needs further definition (5,D)
