ABSTRACT
BACKGROUND/AIMS:
Niti-S ComVi stents are flexible and retain the shape-memory of the original configuration. ComVi stents are effective in preventing tumor ingrowth because polytetrafluoroethylene is inserted between two stent wires. The aim of this study was to examine the efficacy of Niti-S ComVi stents for the palliation of a malignant gastrointestinal obstruction.METHODS:
Between April 2004 and April 2006, 17 patients (20 cases) underwent Niti-S ComVi stenting, using a through-the- scope method. The technical and clinical success, complication, and outcome were analyzed.RESULTS:
Stent insertion was technically successful in 18 cases (90%). Malposition to the afferent loop occurred in 2 cases. Symptomatic improvement was achieved in 14 cases (70%). The mean gastric outlet obstruction score was 0.2 before stenting and 1.6 after stenting. The complications encountered were stent migration (2 cases) and obstruction (5 cases), which were treated by re-stenting and balloon dilatation. Twelve patients died with a median survival of 67 days. Five patients were still alive with a median follow up of 151 days. The overall median stent patency time was 60 days. The mean waist diameter of the stents was expanded to 57% of full expansion immediately after deployment, and 77% after 36 hours.CONCLUSIONS:
Niti-S ComVi stenting is an effective palliative technique for inoperable or postoperative recurrent tumors, and significantly improves the quality of life.
