Objectives: The objective of this study was to evaluate the incidence of post-balloon-occluded retrograde transvenous obliteration (BRTO) ascites/hepatic hydrothorax and rebleeding rate (variceal and non-variceal) in the presence and absence of a transjugular intrahepatic portosystemic shunt (TIPS).
Methods: A retrospective audit of consecutive patients undergoing BRTO was performed (August 2007-October 2010). The population was divided into two groups: patients who underwent BRTO only (BRTO-only group) and those who underwent BRTO in the presence of TIPS (BRTO+TIPS group). Post-BRTO rebleeding was categorized for the source of bleeding. Ascites and/or hepatic hydrothorax were categorized according to clinical severity. Comparisons, utilizing the Kaplan-Meier method, between both groups were made for patient survival, incidence of ascites/hydrothorax, and rebleeding.
Results: Thirty-nine patients underwent BRTO (three technical failures of BRTO-only group). Of the 36 technically successful BRTO procedures, 27 patients (75%) underwent BRTO-only and 9 patients (25%) underwent BRTO in the presence of a TIPS. Pre-BRTO ascites/hydrothorax resolved in BRTO-only vs. BRTO+TIPS in 7% (N=2/27) and 56% (N=5/9), respectively (P=0.006). The ascites/hydrothorax free rate at 6, 12, and 24 months after BRTO for BRTO-only vs. BRTO+TIPS was 58%, 43%, 29%, and 100%, 100%, 100%, respectively (P=0.01). Recurrent hemorrhage for BRTO-only vs. BRTO+TIPS groups, and for the same time periods was 9%, 9%, 21% vs. 0%, 0%, 0%, respectively (P=0.03). The 1-year patient survival of both groups (80-88%) was similar (P>0.05).
Conclusions: This study concludes that the presence of TIPS has a protective value against the development of post-BRTO ascites/hydrothorax as well as recurrent hemorrhage but this does not translate to improved patient survival.

Esophageal Varices as an Independent Predictor of Fatal Outcomes after Balloon-Occluded Retrograde Transvenous Obliteration in Patients with Hepatic Encephalopathy.

Article Synopsis
- The study analyzed 107 patients undergoing balloon-occluded retrograde transvenous obliteration (BRTO) due to uncontrollable hepatic encephalopathy (HE) and assessed the impact of esophageal varices (EVs) on outcomes.
- Patients were divided into two groups based on the presence of EVs, and results showed that those with EVs had significantly shorter event-free survival and overall survival compared to those without EVs.
- The findings suggest that having EVs may indicate a higher risk of complications and mortality following the BRTO procedure in HE patients.

Background And Aims: The study sought to compare the efficacy of endoscopic injection sclerotherapy with cyanoacrylate glue (EIS-CYA) vs EIS-CYA plus a radiologic intervention (RI) (either transjugular intrahepatic portosystemic shunt or balloon-occluded retrograde transvenous obliteration) for secondary prophylaxis in patients with liver cirrhosis who presented with acute variceal bleeding from cardiofundal varices. Primary outcome measure was gastric varix (GV) rebleed rates at 1 year.
Methods: Consecutive cirrhosis patients with acute variceal bleeding from cardiofundal varices were randomized into 2 arms (45 in each) after primary hemostasis by EIS-CYA.

Department of Gastroenterology and Hepatology, KIMS and PBM Hospital, Bhubaneswar, Odisha, India.
Article Synopsis
- Radiological interventions have become essential in treating chronic liver diseases, with techniques like TIPS, TJLB, TACE/TARE, BRTO, and PARTO significantly benefiting patient outcomes.
- The study reviewed 25 hepatic interventions conducted in one center, focusing on five cases with notable complications and their successful management.
- Case highlights include patients with conditions like Budd Chiari Syndrome and decompensated cirrhosis, showcasing the need for careful patient selection and the importance of addressing complications quickly to improve patient outcomes.
Background And Aim: Managing gastric variceal (GV) hemorrhage is more complicated than managing esophageal variceal (EV) bleeding, resulting in significantly higher morbidity and mortality. We aim to compare the outcomes of endoscopic variceal ligation (EVL), transhepatic intrahepatic portosystemic shunt (TIPS), and balloon-occluded retrograde transvenous obliteration (BRTO) in the management of GV bleeding.
Methods: We utilized the National Inpatient Sample (NIS) database from January 2016 to December 2019 to include adult patients with GV hemorrhage.

Background And Study Aims: Balloon-occluded retrograde transvenous obliteration-assisted endoscopic cyanoacrylate injection (E-BRTO) temporarily treats gastric fundic varices draining through gastrorenal shunts (GRS) occluding the GRS with a balloon, then endoscopically injecting cyanoacrylate. We retrospectively examined the safety, feasibility, and efficacy of E-BRTO.
Patients And Methods: We enrolled 85 patients with hepatic cirrhosis plus gastric fundic varices with GRS; 34 underwent E-BRTO.
