Adverse events (AEs) are a major concern, especially in patients with better prognosis and longer survival. The present study aimed to evaluate the AEs of patients who survived longer than 6 months with esophageal stents in place. Methods: This is a retrospective analysis of a prospectively collected database including all patients submitted to esophageal stent placement for the palliation of malignant diseases during the period from February 2009 to February 2014 at a tertiary care academic center who had stents longer than 6 months. Results: Sixty-three patients were included. Mean follow-up was 10.7 months. Clinical success was achieved in all patients, and the median stent patency was 7.1 months. AEs occurred in 40 patients (63.5%), totaling 62 AEs (mean, 1.5 AEs per patient). Endoscopic management of AEs was successful in 84.5% of cases, with a mean of 1.6 reinterventions per patient. The univariate analysis revealed that performance status, age, and post-stent radiotherapy presented a trend to higher risk of AEs. The multivariate analysis revealed that only performance status was associated with AEs (P = .025; hazard ratio, 4.1). Conclusions: AEs are common in patients with long-term esophageal stenting for malignancy. However, AEs were not related to higher mortality rate, and most AEs could be successfully managed by endoscopy. Only performance status was a risk factor for AEs. Our data suggest that metallic stenting is a valid option for the treatment of malignant esophageal conditions, even when survival longer than 6 months is expected.
- Self-expandable metal stent for malignant esophagorespiratory fistula: predictive factors associated with clinical failure(2018) RIBEIRO, Maria Sylvia Ierardi; MARTINS, Bruno da Costa; LIMA, Marcelo Simas de; FRANCO, Matheus Cavalcante; SAFATLE-RIBEIRO, Adriana Vaz; MEDEIROS, Vitor de Sousa; BASTOS, Victor Rossi; KAWAGUTI, Fabio Shiguehissa; SALLUM, Rubens Antonio Aissar; RIBEIRO JR., Ulysses; MALUF-FILHO, FauzeBackground and Aims: Malignant esophagorespiratory fistulas (MERFs) usually are managed by the placement of self-expandable metal stents (SEMSs) but with conflicting results. This study aimed to identify risk factors associated with clinical failure after SEMS placement for the treatment of MERFs. Methods: This was a retrospective analysis of a prospectively maintained database used at a tertiary-care cancer hospital, with patients treated with SEMS placement for MERFs between January 2009 and February 2016. Logistic regression was used to identify predictive factors for clinical outcomes and to estimate the odds ratio (OR) and the 95% confidence interval (CI). The Kaplan-Meier method was used for survival analysis, and comparisons were made by using the log-rank test. Results: A total of 71 patients (55 male, mean age 59 years) were included in the study, and 70 were considered for the final analysis (1 failed stent insertion). Clinical failure occurred in 44% of patients. An Eastern Cooperative Oncology Group (ECOG) performance status of 3 or 4 and fistula development during esophageal cancer treatment were associated with an increased risk of clinical failure. ECOG status of 3 or 4, pulmonary infection at the time of SEMS placement, and prior radiation therapy were predictive factors associated with lower overall survival. Dysphagia scores improved significantly 15 days after stent insertion. The overall stent-related adverse event rate was 30%. Stent migration and occlusion caused by tumor overgrowth were the most common adverse events. Conclusion: SEMS placement is a reasonable treatment option for MERFs; however, ECOG status of 3 or 4 and fistula development during esophageal cancer treatment may be independent predictors of clinical failure after stent placement.
