A comparative study of self-expandable metallic stent (SEMS) and transanal drainage tube(TDT) in management of malignant large-bowel obstruction (MLBO)

Abstract

The aim of this study is to identify an effective approach to MLBO, focusing on the choice of SEMS and TDT at the initial stage of the conditions. Patients and Methods : Retrospective reviews were performed on 21 patients who underwent either SEMS (n=10) or TDT (n=11) placement between January 2011 and December 2014. Among the collected data and records, technical success rates and effectiveness of the intervention, subsequent surgical procedures including colostomy, and any severe complications were evaluated. Results : SEMS were successfully inserted in all ten cases among which three went to surgery and seven stayed with palliative therapy. TDT was successsfully placed in ten out of eleven cases while effective decompression was achieved in nine cases. SEMS were may potentially be more effective than TDT in relief of obstruction (p=0.0956) .
Placement of SEMS is likely to be an effective therapy for MLBO in short-term patency, decompressive effects, and palliative therapy.
