2224 A Rare Complication of Post-TIPS Related Acute Cholecystitis

Abstract

INTRODUCTION: Amongst the well documented TIPS-related biliary complications, there has been no reported case of acute cholecystitis. Multiple multicenter RCT comparing TIPS to large volume paracentesis reported better control of ascites, lower diuretic doses or cessation of diuretics in approximately 75% of the patients. Biliary related complications include biliary venous fistulas, biloma or biliary occlusion secondary to biliary compression. This may be the first reported case of Post TIPS acute cholecystitis. CASE DESCRIPTION/METHODS: 67-year-old white male with end-stage NASH cirrhosis was hospitalized 6 months ago for diuretic-resistant ascites. Prior to admission, he has required weekly large volume paracentesis. While hospitalized, he underwent large-volume paracentesis and was treated for acute urinary tract infection. TIPS was placed two weeks post discharged and ascites improved. Three days later while undergoing further evaluation, a liver ultrasound showed gall bladder wall thickening and gall stones, suggestive of acute cholecystitis with cholelithiasis. He subsequently developed severe pancytopenia and worsening liver function test. A percutaneous cholecystostomy tube was placed for gall bladder decompression along with a 14-day course of IV antibiotics. He later developed Choledocholithiasis and required ERCP and cholangioscopy. Multiple stones were extracted from the bile duct and complete fibrosis of the cystic duct was noted. The patient required multiple hospitalizations since then, frequent paracentesis and treatment for SBP. He recently underwent OLT with cholecystectomy which was technically challenging. DISCUSSION: TIPS insertion has been established as an effective second-line treatment for refractory ascites. There are 3 documented category of TIPS complications; technical, portosystemic and unique shunt related but no known reported case of acute cholecystitis. Hepatic encephalopathy occurs in approximately 30% of patients, early thrombosis or delayed shunt stenosis occurred in 22- 50% of patients prior to the development of polytetrafluoroethylene-covered stents. The technical intricacy of this intervention poses a potential risk, and morbidity rates as high as 20%. A broad understanding of the uncommon and unique complications can potentially decrease post-op-related complications especially in a patient undergoing OLT It is necessary for clinicians who perform this procedure to be aware of the clinical spectrum of TIPS-related complications and their management.
