Status of transjugular intrahepatic portosystemic shunt for portal hypertension in China: A national survey analysis

AimThe transjugular intrahepatic portosystemic shunt (TIPS) procedure has been performed in China for 30 years, but our understanding of the status and difficulties associated with the use of TIPS for portal hypertension is incomplete. This study aims to investigate the current situation of the use of TIPS for portal hypertension, which should aid the development of TIPS in China.MethodsThis study involved a questionnaire survey, initiated by the China Portal Hypertension Alliance (CHESS) to investigate the use of TIPS for portal hypertension in China. Questionnaires were released on the Internet between August 16, 2022 and September 16, 2022. Detailed information was collected from 545 hospitals contracted by the CHESS in China, which performed TIPS surgery in 2021.ResultsThe 545 hospitals covers the majority of hospitals in China that conduct TIPS intervention. In the survey, a total of 13,527 TIPS interventions were carried out with 94.1% (498/545) of them had a system of routine follow-up after TIPS. The majority (42.6% [232/545]) believed that the main indication of TIPS was the control of acute bleeding. Overall, 48.1% (262/545) carried out early or pre-emptive TIPS, 53.0% (289/545) carried out TIPS for cavernous transformation of the portal vein, and 81.0% (441/545) chose routine embolization of collateral circulation during operation. Most used coils (97.0% [475/490]) and biological glue (72.0% [353/490]) as embolic materials, and 78.5% (428/545) routinely performed intraoperative portal pressure gradient measurements. When selecting TIPS stents, 57.1% (311/545) chose viator-specific stents, and 57.2% (312/545) chose conventional anticoagulation after TIPS. Conventional anticoagulation after TIPS is over a time interval of 3-6 months (55.4% [173/312]). The limitation of TIPS surgery is mainly its cost (72.3% [394/545]) and insufficient understanding of the procedure by doctors in other related departments (77.4% [422/545]). Most of the hospital teams accept the use of domestic instruments in TIPS surgery (92.7% [505/545]).ConclusionsThis survey shows that TIPS is an essential part of the treatment of portal hypertension in China. TIPS is widely used in Chinese patients with portal hypertension, and this survey presents a more comprehensive picture of the options and difficulties encountered in the implementation of TIPS. In the future, it is necessary to promote TIPS technology and further standardize surgical indications, routine operations, and instrument application. A survey analysis of TIPS for portal hypertension in China. TIPS: Transjugular intrahepatic portosystemic shunt.Key points image The findings of this paper are the first systematic and comprehensive description of the status of TIPS intervention in China, and a comprehensive understanding of the current number of TIPS cases, indications, surgical details, and difficulties faced in China. This paper includes a larger number of cases, a detailed questionnaire design, and realistic results, which lays a good foundation for future large-scale cooperation in the field of TIPS in China.
