Background and Aims
Electrocautery-tip lumen-apposing metal stents (EC-LAMSs) have extended the indications
of therapeutic EUS. We aimed to retrospectively evaluate safety and technical and
clinical success of a newly developed EC-LAMS, the Hot-Spaxus (Taewoong Medical Co,
Gimpo, Korea), for various EUS-guided procedures.
Methods
We included and retrospectively analyzed consecutive patients at 8 tertiary care referral
centers who had undergone EUS interventional procedures using the Hot-Spaxus between
October 2018 and February 2021.
Results
Of 58 included patients (male-to-female, 36:22; mean age, 63.5 ± 14.9 years), 29 had
undergone pancreatic fluid collection drainage (50%), 22 (37.9%) biliary drainage
for malignant distal obstruction, 3 (5.1%) gallbladder drainage for acute cholecystitis,
3 gastroenteroanastomoses, and 1 (1.7%) pelvic collection drainage. Technical success
was achieved in 54 of 58 patients (93.1%) and clinical success in all 58. Adverse
events occurred in 6 patients (11.1%): 2 early (3.7%), 1 late (1.8%), and 3 long term
(5.6%). The outcomes were similar to those observed in a control group of patients
treated with the Hot-Axios (Boston Scientific, Marlborough, Mass, USA), the other
available EC-LAMS.
Conclusions
Our study showed that the novel EC-LAMS has high technical and clinical success rates
for various interventional EUS indications. Future multicenter prospective studies
will better clarify the role of this new EC-LAMS for different indications.
