Patients
Between February 2007 and May 2008, 45 patients with dysphagia caused by esophageal, gastric cardia, or lung cancer were consecutively enrolled in the study. Inclusion criteria were inoperable malignant obstruction of the esophagus or gastric cardia caused by esophageal, cardia, or lung carcinoma. All patients gave written informed consent. Exclusion criteria were an obstruction length of more than 12 cm, tumor growth within 2 cm of the upper esophageal sphincter, and a fistula between the
Functional outcome
Successful placement of 46 SX–ELLA stents was achieved in all 45 patients. Because 1 patient was lost to follow-up, clinical characteristics of 44 patients are shown in Table 1. In all 25 (57%) patients with a tumor located in the distal esophagus or gastric cardia, the stent crossed the gastroesophageal junction. Eight patients died before the 4-week follow-up, with 1 of them having symptoms of hemorrhage and upper abdominal pain that were considered to be related to stent insertion. After 4
Discussion
In this prospective follow-up study of 44 patients, we demonstrated that the SX–ELLA stent provided good symptomatic relief of malignant dysphagia. In addition, we found a low rate of tissue overgrowth (KM = 8%), but a similar frequency of stent migration (KM = 20%), as previously reported with other expandable stents.1, 9, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21 In addition, despite the single-wire, braided, low-trauma design, the frequency of hemorrhage and fistula formation was considerable

In previously published prospective studies with different types of FCSEMS, migration rates ranged from 6% to 35% in malignant dysphagia [10–12,21–24]. In our series stent migration occurred in 7 out of 53 (13%) patients.
