ABSTRACT
BACKGROUND/

AIMS:

Endoscopic self expandable metallic stent (SEMS) has become the palliative treatment of choice for inoperable malignant esophageal stricture. However, covered and uncovered stents carry limitations such as stent migration and tumor ingrowth, respectively. A double esophageal stent has been developed to overcome these problems. The aim of this study was to evaluate the usefulness of double esophageal stent (outer uncovered stent and inner covered stent) for palliation of malignant esophageal stricture.

METHODS:

Between February 2001 and November 2006, 32 patients with malignant esophageal stricture were treated with double esophageal stents. The patients were retrospectively assessed for the technical outcome, the clinical outcome and the complications of the process.

RESULTS:

Stent implantation was successful in all 32 patients (100%). The dysphasia score significantly improved from a mean of 3.22 to 1.63 (p<0.001) for all 32 patients. Eight patients had recurrent dysphagia due to stent overgrowth (6/32, 18%), stent migration (1/32, 3%) and tumor ingrowth (1/32, 3%). Symptomatic gastroesophageal reflux occurred in six patients (18%). Aspiration pneumonia occurred in two patients (6%).

CONCLUSIONS:

Double esophageal stent is effective for symptomatic relief of malignant esophageal stricture. It seems to reduce tumor ingrowth and stent migration, but it has limitations such as tumor overgrowth and GERD.
