Abstract

Backgrounds/Aims: Post-operative pancreatic fistulas (POPF) and fluid collections (POPFC) remain significant sources of morbidity and mortality after pancreatic resections. There remains a paucity of literature describing endoscopic ultrasound (EUS) guided drainage of POPFC using a Hot AXIOS™ lumen apposing metal stent (LAMS).
Methods: We conducted a retrospective study, encompassing all consecutive patients with POPFC managed using Hot AXIOS™ LAMS at our institution between January 2017 and December 2019. Primary outcome measures were technical and clinical success. Secondary outcome measures were adverse events and recurrence rates.
Results: Five patients underwent EUS guided drainage using Hot AXIOS™ LAMS during the study period. Mean age of patients was 67.8 ± 2.16 years. The majority (60.0%) of patients were males. Median duration of symptom onset after surgery was 9 days. All patients presented with abdominal pain. Median size of the collection measured on computed tomography was 91 mm. Median interval time between symptom onset and EUS drainage was 30 days. Two patients required percutaneous drainage prior to EUS guided drainage. Technical and clinical success were achieved for all patients. No adverse events were observed. Median duration of follow-up was 90 days. No recurrence of collection occurred during the follow-up period.C
Conclusions: EUS guided drainage of POPFC using Hot AXIOS™ LAMS is a safe and effective treatment modality with technical and clinical success rates of 100% in our experience.
