Rationale and Objectives
Timely removal of esophageal stents can help avoid or reduce the occurrence of complications.
This study was aimed at elucidating the interventional technique for the removal of
self-expanding metallic esophageal stents (SEMESs) under fluoroscopy and analyzing
its safety and efficacy.
Materials and Methods
The medical records of patients who underwent removal of SEMESs by interventional
techniques under fluoroscopy were retrospectively analyzed. Furthermore, the success
and adverse event rates for different interventional techniques of stent removal were
analyzed and compared.
Results
Overall, 411 patients were included, and 507 metallic esophageal stents were removed.
There were 455 and 52 fully and partially covered SEMESs, respectively. According
to the stent indwelling time, benign esophageal diseases were divided into two groups:
≤68 days and >68 days. There was a significant difference in the incidence of complications
between the two groups (13.1% and 30.5%, respectively, p < .001). The stents in cases of malignant esophageal lesions were divided into the
following two groups: ≤52 days and >52 days. Intergroup differences in complication
incidence were not significant (p = .81) Further, there was a significant difference in removal time between the recovery
line pull and proximal adduction techniques (4 and 6 minutes, respectively, p < .001). In addition, the recovery line pull technique was associated with a lower
rate of complications (9.8% vs 19.1 %, p = .04). There was no statistical difference in the technical success rate and incidence
of adverse events between the inversion and stent-in-stent techniques.
Conclusion
Interventional technique to remove SEMESs under fluoroscopy is safe, effective, and
worthy of clinical application.
