Highlights |
• | The main limitation of FCSEMS is migration, requiring endoscopic re-interventions. |
• | Attempts to reduce stent migration include anchoring the stent to the esophageal wall as the placement of trough-the-scope or over-the-scope clip clips. |
• | FCSEMS with different anti-migration systems have been used. |
• | Despite the anti-migration features, stent migration remains a major cause of recurrent dysphagia especially when stent is placed in the upper esophagus or across the esophago-gastric junction. |
Abstract |
Background |
Self-expanding metal stents (SEMS) placement is primarily indicated to palliate dysphagia for patients with expected short-term survival. We aimed to assess the migration rate and other stent-related adverse events (AEs) of a fully covered SEMS with an anti-migration system (FCSEMS-AMS) for palliation of malignant dysphagia.
Methods |
This is a prospective study including patients with inoperable esophageal cancer that received a FCSEMS-AMS (Taewoong, Niti-S Beta™), in five tertiary-care endoscopic centers from January 2014 to February 2016.
Results |
Fifty-three consecutive patients were enrolled. Tumor location was proximal, mid and distal esophagus±esophago-gastric junction (EGJ) in 6, 14, and 33 cases, respectively. Overall, non-severe AEs were reported in 18 patients (34.0%), 13 of them required an additional endoscopic procedure. Migration occurred in 7 patients (13.2%): 3 from the upper and 4 from the lower esophagus and EGJ. Stent retrieval was necessary in one patient due to intolerable pain. Food bolus impaction and tumor overgrowth occurred in 2 patients (3.8%) and 4 (7.5%) patients respectively. Four patients complained of gastroesophageal reflux as late AEs. Median follow-up was 19.3 months. Dysphagia significantly improved until 3 and 6 months from stent insertion (median score before FCSEMS-AMS: 3, vs median score: 1). Median dysphagia-free time was 10 months.
Conclusions |
Placement of the Taewoong, Niti-S Beta™ stent appeared to be a safe and effective treatment of malignant dysphagia. The anti-migration system reduced the overall migration rate, although it remained high in strictures located in the upper esophagus and when the stent was placed across the EGJ.
