Background
/Aims: Self-expandable metal stents (SEMS) have been used in the palliation of malignant obstruction. The purpose of this study was to evaluate the effectiveness, safety, and outcome of SEMS using through-the- scope (TTS) method in the patients with malignant upper gastrointestinal obstruction including recurrent gastric cancer after gastrectomy. Methods: Thirty one patients (36 stents) were treated with SEMS between October 2000 and June 2004; nineteen had inoperable malignant gastric outlet obstruction, ten had recurrent gastric cancer after gastrectomy, and two had metastatic duodenal cancer. We analyzed the technical and clinical success, complication, and outcome. Results: The technical success rate was 88.8% (32/36 stents) in total cases; 95.0% (19/20) in malignant gastric outlet obstruction, 84.6% (11/13) in recurrent gastric cancer after gastrectomy, and 66.7% (2/3) in metastatic duodenal cancer. The success rate of dietary intake was 86.1% (31/36 stents). Complications occurred in 7 of 36 stents (19.4%), including stent migration (1 patient), aspiration pneumonia (1 patient), and recurrent obstruction (5 patients). The mean survival duration period was 118.1⁑180.2 days and mean patency period was 92.2⁑89.9 days. Conclusions: SEMS using TTS is an effective, safe, and less invasive palliative treatment in malignant upper gastrointestinal obstruction including recurrent gastric cancer after surgery.
