Stenting of the esophagus in the course of the malignant dysphagia in elderly patients

Abstract

Esophageal cancer is a disease with difficult clinical management, and palliative therapy is the only predominant treatment. This retrospective study analyses the results of clinical management of elderly patients (>75 years of age) who were treated with esophageal stenting for malignant dysphagia due to primary esophageal cancer, including squamous cell carcinoma (SCC), esophageal adenocarcinoma (EAC), as well as secondary esophageal malignant strictures due to non-small cell lung cancer (NSCLC). Patients with esophago-respiratory fistula (ERF) were also included in the study. This study included 166 patients aged 75–88 (mean age, 78) years. Nine (5.4%) patients had upper malignant esophageal stenosis, 48 (28.1%) had the middle, 43 (25.9%) in the lower part of the esophagus, 49 (29.5%) patients had EAC-related stenosis, and 17 (10.2%) patients reported lung cancer-related esophageal stenosis. Dysphagia was rated at 2.8 (range, 2–3) before stenting and at 1.2 (range, 1–2) after the stenting procedure. Seven (4%) patients experienced stenting migration, 12 (7.2%) had granulation tissue overgrowth and prosthesis obstruction, two (1.2%) developed respiratory failure, and one (0.6%) patient died. Twelve (7.2%) patients were treated for ERF with double-stenting, and three (1.8%) patients developed a secondary fistula after the stent implantation. The mean survival of patients with esophageal cancer and ERF was 101.8 days and 62.5 days, respectively. Esophageal stenting has proven a safe procedure in patients over 75 years of age. It has a low rate of stenting obstruction and migration. Patients with ERF are a particularly difficult group to treat, show very poor outcomes and short survival rates.
