Popis: To evaluate the long-term palliative effect of self-expanding nitinol esophageal stents in patients with malignant dysphagia.One hundred patients with severe dysphagia secondary to malignant esophageal strictures were treated with self-expanding nitinol stents. The strictures were caused by squamous carcinoma (n = 43), adenocarcinoma (n = 28), anastomotic tumor recurrence (n = 14), and mediastinal tumor (n = 15).One hundred six stents were successfully positioned in 100 patients. Attempts to insert a second, coaxial stent were unsuccessful in two patients; a second stent was placed incorrectly in another patient. Statistically significant (P.001) reduction of dysphagia was noted after expansion of the stents. Complications consisted of incomplete expansion secondary to stent twisting (n = 4), stent migration (n = 4), tumor ingrowth (n = 17), tumor overgrowth (n = 3), food impaction (n = 5), fracture of stent wires (n = 2), benign strictures at stent edges (n = 2), tumor bleeding (n = 3), and esophagorespiratory fistula (n = 5). The primary patency rate was 75% (77 of 102 stents); the secondary patency rate was 94% (96 of 102 stents). The survival time (mean, 6.2 months; range, 0.1-47 months) varied with the diagnosis.Placement of self-expanding nitinol stents is safe and has a good long-term palliative effect on dysphagia in patients with malignant esophageal strictures.
