Purpose: To identify risk factors that could potentially predict late complications associated with metallic stents in malignant esophageal stenosis. Material and methods: Retrospective analysis of patients with metallic stent implantation for malignant esophageal stenosis between 2005 and 2019. The incidence and type of complications (stent dislodgement, stent obstruction, fistula) were investigated according to the type (Ella, Wallflex, Boubella, Egis), stent length, implanting surgeon, patient age, patient survival, adjuvant chemotherapy or radiotherapy, characteristics of the malignant stenosis (length, width, contour), and extent of prestenotic dilatation. Radiological parameters were evaluated from fluoroscopy of the esophagus before and after stent implantation; other information was obtained from the hospital information system. Among statistical methods, Mann-Whitney test and t-test were used for continuous variables, Chi-squared test for categorical variables, and Kaplan-Meier and log-rank test for survival analysis. Results: The study included 115 esophageal metallic stents in 96 consecutive patients. There were 37 stents in the proximal esophagus (32.2%) and 78 stents in the distal esophagus (67.8%). Complications were observed in 25 (21.7%) stents. Median survival from stent implantation was 132 days. A significantly higher risk of stent dislocation was observed with shorter stents (96±16 vs 116±24 mm; p=0.008). Other parameters were not significantly associated with complication rates. Conclusion: Stent length was the only observed statistically significant factor in the complication rate of metallic stents implanted in malignant esophageal stenosis, with shorter stents having a significantly higher risk of dislocation than longer stents.
