Abstract:
Objective To study the technique of placemen t of Nitinol stent for relieving malignant pylorus or duodenal obstruction, and to assess its clinical effectiveness.Methods In this group the strictures were caused by gastric car cinoma at the antrum (n=2), anastomosis site of previous gastrojejunostomy (n=2 ), gastric carcinoma at the cardia (n=4), colon cancer (n=1), pancreatic cancer (n=3) and duodenal cancer (n=4). Under fluoroscopic guidance the Nitinol stent w as inserted into pylorus or duodenal obstruction sites via oral cavity in all ca ses. Complications and clinical status were investigated during the study period .Results Successful stent placement was achieved in 15 cases. Tw o patients had undergone double stent placement (pylorus stent and bile duct ste nt). The rate of improvement in abdominal distention and vomiting 1 week after p rocedure was 73 3% and 86 7% respectively. Procedure-related complications ne ver occurred.Conclusion Nitinol alloy network stent is a safe and efficaciou s method for palliating malignant pylorus or duodenal obstruction, and improves patient's living quality.
