ABSTRACT
BACKGROUND AND AIM:
Re-intervention after stent placement for malignant hepatic hilum obstruction (HBO) is challenging. endoscopic ultrasound-guided biliary drainage (EUS-BD) has been developed as an alternative method for failed endoscopic retrograde cholangiopancreatography (ERCP). In this retrospective study, the clinical utility of EUS-BD as a rescue drainage technique for HBO patients who failed re-intervention under ERCP guidance was evaluated.METHODS:
Between April 2012 and August 2015, patients with HBO were enrolled. Patients' characteristics, kinds of metallic stents, configuration of stent placement, overall survival, stent patency, and results of re-intervention were reviewed, along with the re-intervention technical success rate.RESULTS:
The biliary stricture type was Bismuth type IV in 59% (23/39) and types IIIa and b in 20.5% (8/39) each. Biliary metallic stent placement was bilateral in 38.5% (15/39), and unilateral in 61.5% (24/39). Primary stent dysfunction was observed in 71.8% (28/39) of cases. Planned re-intervention under ERCP guidance was attempted in 26 patients. The technical success rate was 62% (16/26). For the 10 patients who failed re-intervention under ERCP guidance, EUS-BD was planned. The technical success rate was 100% (10/10). The procedure time was 25.8 min. Adverse events were not seen in any patients. Stent patency after re-intervention was not significantly different between ERCP (165 days) guidance and EUS-BD (152 days) guidance (P = 0.463)CONCLUSIONS:
In conclusion, EUS-BD as a re-intervention method for metallic stent obstruction was safe and feasible. If ERCP was failed, EUS-BD may be one of option as re-intervention method for high-grade hilar stricture.Palavras-chave
