ABSTRACT
BACKGROUND:
Esophageal stenting is an important intervention for managing malignant and benign dysphagia, with stent migration representing a common drawback. This systematic review with meta-analysis aimed to assess the benefit of stent fixation over nonfixation.METHODS:
A systematic search was performed in MEDLINE, Cochrane, Scopus, and ClinicalTrials.gov databases until January 2023 for comparative studies evaluating the migration rates of esophageal stents with versus without (control) fixation. The primary outcome was migration rate. Secondary outcomes included adverse event rate. A subgroup analysis stratified the results based on different fixation techniques suturing, over-the-scope (OTS) clipping, and through-the-scope (TTS) clipping. Meta-analysis was based on a random effects model and the results were reported as odds ratios (ORs) with 95â%CIs.RESULTS:
10 studies (1014 patients) were included. The rate of stent migration was significantly lower after fixation (OR 0.20, 95â%CI 0.11-0.37; I2 â=â59â%, Pâ=â0.01). The adverse event rate was similar between fixation and control groups (OR 0.65, 95â%CI 0.28-1.52; I2 â=â55â%, Pâ=â0.06). In the subgroup analysis, all fixation techniques remained superior to nonfixation of stents (suturing OR 0.23, 95â%CI 0.10-0.53; OTS clips OR 0.31, 95â%CI 0.17-0.58; TTS clips OR 0.10, 95â%CI 0.03-0.38); however, only the OTS and TTS clip groups achieved nonsignificant heterogeneity (I2 â=â0â%, Pâ=â0.67 and Pâ=â0.73, respectively). No difference between techniques was recorded for migration rates.CONCLUSION:
Esophageal stent fixation was associated with significantly lower migration rates compared with nonfixation of stents, regardless of fixation technique and stenting indication.
