Overview

Introduction:

In the last decade the indications for endosonographic (EUS) guided drainages have significantly broadened mainly due to the advent of novel lumen apposing metal stents (LAMS).

Method:

The aim of this retrospective, consecutive review (November 2016–May 2018) was to evaluate technical safety, clinical success, and the number of procedure-related and late complications of EUS guided drainage using the Hot AXIOS stent. Among a cohort of 20 patients, 9 had a malignant diagnosis and 11 had a benign diagnosis. Seven patients underwent pathological fluid drainage, six patients underwent transluminal cholecystostomy, six patients were treated with LAMS to gain access to the bile duct, and one patient underwent gastro-enterostomy.

Results:

The technical success rate was 100 % and the clinical success rate was 95 %. There were two procedure-related complications (10 %), stent malposition and mild bleeding. There was one late complication of clogging of the LAMS with emanating cholangoitis, which was solved by endoscopic re-intervention. The average follow-up period for malignant diagnoses was 103 days. Conclusion: Evaluation of the cohort confirmed the high technical and clinical success of EUS guided drainage using Hot AXIOS stents and the low percentage of complications of this procedure.

Key words:

endoscopic ultrasound-guided transmural drainage – lumen-apposing metal stent – pancreatic fluid collections – biliary drainage – enteroenterostomy
