Double-balloon enteroscopy-facilitated cyanoacrylate-injection endotherapy of small-bowel varices: an international experience from 2 European tertiary centers (with videos).

BACKGROUND AND AIMS:Small-bowel varices (SBVs) are an uncommon consequence of portal hypertension. Radiologic intervention is usually considered for first-line management. When radiologic intervention is not possible, management options become very limited. The aim of this study was to evaluate the usefulness of double-balloon enteroscopy (DBE)-facilitated cyanoacrylate-injection endotherapy of SBVs. METHODS:This was a retrospective review of DBE-facilitated cyanoacrylate-injection endotherapy of SBVs (December 2015 to October 2016). RESULTS:Ten DBEs were performed in 6 patients (4 women; median age, 68.5 years). No radiologic or surgical options were deemed feasible. Thirteen nests of SBVs were identified and injected with cyanoacrylate glue without hemorrhagic or embolic adverse events. At the 30-day follow-up after therapy, only 1 patient had experienced a mild recurrence of mid-gut bleeding; this was managed conservatively. One patient presented with acute GI bleeding 7 months later, and a repeat DBE with cyanoacrylate-injection endotherapy was successfully performed. One patient succumbed to his underlying advanced cholangiocarcinoma after 2 months. The remaining patients had a median follow-up of 12 months without any recurrent GI bleeding. CONCLUSIONS:DBE-facilitated cyanoacrylate-injection endotherapy of SBVs appears to be a safe and effective option when other first-line options are not feasible.
