EUS-Guided Thrombin Injection and Coil Implantation for Gastric Varices: Feasibility, Safety, and Outcomes.
Gastrointestinal Endoscopy 2024 Februrary 4
BACKGROUND AND AIMS: Gastric varices (GV) are reported in up to 20% of patients with portal hypertension, and bleeding is often more severe and challenging than oesophageal variceal bleeding. There is limited data on prophylaxis of GV bleeding or management in the acute setting, and different techniques are utilised. This study aims to evaluate outcomes following endoscopic ultrasound (EUS) guided placement of coils in combination with thrombin to manage GV.
METHODS: We retrospectively reviewed all patients treated with combination EUS-guided therapy with coils and thrombin between October 2015 and February 2020.
RESULTS: 20 patients underwent 33 procedures for GV therapy; 16/20 (80%) were type 1 Isolated GV (IGV1), and the remainder were type 2 Gastroesophageal Varices (GOV2). Median follow-up was 842 days (Interquartile range (IQR) 483-961). 17/20 (85%) had underlying cirrhosis, the most common aetiologies being alcohol-related liver disease and non-alcoholic steatohepatitis (NASH). The median Child-Pugh (CP) score was 6 (IQR 5-7). In 11/20 (55%) cases, the indication was secondary prophylaxis to prevent rebleeding; in 2/20 (10%), the bleeding was acute. Technical success was achieved in 19/20 (95%) of cases. During follow-up, the obliteration of flow within the varices was achieved in 17/20 (85%) cases. The 6-week survival was 100%, and 2 adverse events were reported: cases of rebleeding at day 5 and day 37; both rebleeds were successfully managed endoscopically.
CONCLUSIONS: EUS-guided GV obliteration combining coil placement with thrombin, in our experience, is technically safe with good medium-term efficacy. A multicenter randomised controlled trial comparing different treatment strategies would be desirable to understand options better.
