Abstract
Background Proximal esophageal stents are poorly tolerated and have a high risk of complications.
We report our experience using fully covered, biliary, self-expandable metal stents
(B-SEMS) and narrow-diameter, esophageal, self-expandable metal stents (NDE-SEMS)
for this group of patients.
Methods 24 patients underwent placement of B-SEMS or NDE-SEMS for proximal esophageal lesions
between 1 January 2011 and 31 July 2016. The outcomes included improvement of dysphagia,
healing of fistulas, and adverse events.
Results 10 patients received B-SEMS and 14 had NDE-SEMS. Median follow-up time was 11.5 months
(range 0.5 – 62 months). In both cohorts, stents were left in place for a mean of
6 weeks. The dysphagia score decreased in 7 (70 %) and 10 (71.4 %) patients, and fistulas
resolved in 3/5 (60.0 %) and 5/8 (62.5 %) patients with B-SEMS and NDE-SEMS, respectively.
Stent migration occurred in three patients (30.0 %) with B-SEMS and five patients
(35.7 %) with NDE-SEMS.
Conclusions Both stents were well tolerated and resulted in overall improvement of dysphagia
in 70.8 % of patients. B-SEMS appeared to be more favorable for cervical esophageal
lesions with narrower diameters, while NDE-SEMS may be better for more distal lesions.
