摘要

Background

The placement of an esophageal self-expandable metal stent (SEMS) is an effective palliative treatment for inoperable malignant esophageal stricture. However, despite successful stent placement, some patients continue to experience persistent dysphagia. We aimed to evaluate the predictive factors of clinical outcomes after endoscopic SEMS placement for malignant esophageal stricture.

Methods

Between November 2008 and January 2024, 220 patients who underwent successful endoscopic SEMS placement for malignant esophageal stricture in an academic referral center were included in the analysis. We retrospectively evaluated variables associated with clinical outcomes following successful SEMS placement using univariate and multivariate analyses.

Results

The clinical success rate of endoscopic SEMS placement was 77.7%. The mean age of the patients was 78 years with a male predominance (82.7%). The most common causes were squamous cell esophageal carcinoma (59.5%) and gastric cancer (25.9%). Endoscopic passage was not achievable in 31.4% of patients. A poor performance status (Eastern Cooperative Oncology Group [ECOG] performance status 2–3) was observed in 42.3% of patients, severe dysphagia (water intake only) in 67.3%, and carcinomatosis peritonei in 11.8% of patients. Narcotics were required for analgesia after stenting in 37.7% of patients. Multivariate analysis performed with significant variables determined using univariate analysis showed that need for narcotics after stenting (p = 0.020, odds ratio [OR] 2.768, 95% confidence interval [CI] 1.178–6.504), presence of carcinomatosis peritonei (p = 0.037, OR 2.992, CI 1.067–8.391), and poor performance status (ECOG 2 ~ 3) (p = 0.001, OR 5.076, CI 2.024–12.658) were significant predictive factors of clinical failure after stenting.

Conclusion

The need for narcotics after SEMS placement, presence of carcinomatosis peritonei, and poor performance status (ECOG 2–3) are significantly associated with clinical failure of palliative SEMS placement.
