OP18 The story of transjugular intrahepatic portosystemic shunt (TIPSS) at the Royal Free Hospital, 2021–2022: indications and outcomes of 84 procedures

Transjugular intrahepatic portosystemic shunt (TIPSS) is an effective treatment for decompression of portal hypertension and is most commonly indicated in patients with chronic liver disease (CLD) or portal vein thrombosis (PVT). It is a technically challenging intervention. CLD patients are often frail with comorbidities conferring increased procedural risk. We tell the story of one year of procedures at the Royal Free Hospital (RFH), one of the major centres for TIPSS in Europe.A retrospective electronic casenote review was carried out for all patients who underwent TIPSS procedure at the RFH between April 2021 and April 2022. The outcomes of interest were success rate, complications and survival including those who went on to transplantation. A successful procedure was defined as a correctly placed stent with no procedural complications and symptom resolution. Eighty-four (84) patients underwent TIPSS during the 12-month period. Of these, 3 were abandoned: 2 because portal hypertension was absent on direct measurement and 1 due to anatomical infeasibility. Of the 81 completed, the most common indication was diuretic-intolerant ascites (n=32), followed by variceal bleeding (n=27), PVT (n=14), and other indications (n=8). The clinical success rates post-TIPSS for each indication are as follows. For diuretic intolerant ascites, 53.1% (17/32) of patients no longer require large volume paracentesis (LVP), 28.1% (9/21) require LVP at a reduced frequency, 6.3% (2/32) have been transplanted and 1 patient continues to have LVP at the same rate. For variceal bleeding, 85.2% (23/27) of patients have had no further episodes of bleeding. For PVT, 85.7% (12/14) of TIPSS remain patent with no patient requiring surgical intervention. No procedural complications were reported. Overall survival post-TIPSS is 87.7% (71/81) with procedure-related mortality accounting for no deaths. 8 patients who received TIPSS went on to be listed for liver transplant, of those 3 successfully received a graft, 4 remain listed and 1 has died while listed.A high number of TIPSS procedures were performed. The majority were successful with favourable clinical outcomes. Major challenges faced by the service during this time included staff shortages, bed capacity, transfer logistics and the wider impacts of the COVID-19 pandemic. This service depends on the collective expertise and close working of multiple specialties including hepatology, interventional radiology, intensive care and anaesthet
