DEDICATED STENT WITH SHORT PROXIMAL HEAD DESIGN FOR LESIONS AFFECTING THE CERVICAL OESOPHAGUS: CUMULATIVE EXPERIENCE IN A REFERRAL CENTRE

Aims Analysis of our experience with this type of esophageal stent. Evaluation of its feasibility, safety and efficacy.

Methods Retrospective, single-center, and descriptive study. All those patients in whom a NITI-S Cervical Esophageal Stent (Taewoong Medical) was placed between 2012 and 2021 were identified from a specific stent-database. Demographics, technical and clinical data were collected from diagnostic tests and our health service provider.

Results Seventeen patients were identified. Demographic and clinical characteristics are summarized in [Table 1]. The most used stent size was: ESP1610FV (58%). Technical success was 82%. Proximal end-flare deployment: 16cm from incisors (range: 12-19cm). Clinical success (oral diet tolerance) was 100%. Adverse events: 2 distal migrations, 1 ingrowth, with endoscopic resolution; 1 proximal migration and 2 intolerances due to pain that required removal. Mean follow-up: 3 months (SD±5.6). Up to 80% of the cases passed away and were related to the malignant disease’s progression.

Table 1

Gender (Male/Female)	11 (65%) / 6 (35%)
Age	Mean: 69 years
Stent Indication (Stenosis/Fistulae/Perforation/Transit reconstruction)	12 (70.6%) / 3 (18.2%) / 1 (5.9%) / 1 (5.9%)
Malignant origin (Yes/No)	13 (76%) / 4 (14%)
Type on neoplasia (Squamous cell esophageal carcinoma / Esophagus adenocarcinoma / ORL malignancy)	8 (61%) / 1 (7.6%) / 4 (31.3%)

Conclusions This is one of the most extensive case series reporting the use of this dedicated cervical oesophageal stent. The main clinal indication is palliative for severe dysphagia. This stent seems to be effective and a safe option for cervical locations.
