Self-expanding metal stent placement for the treatment of malignant gastroduodenal obstruction / 中国微创外科杂志

ABSTRACT

Objective To evaluate the efficacy of metal stent placement for the treatment of malignant gastroduodenal obstruction. Methods Medical records of 24 patients with gastroduodenal obstruction secondary to malignant tumors (gastric cancer, 19 patients; pancreatic cancer, 4 patients; postsurgical biliary duct cancer, 1 patient) from October 2002 to November 2004 were reviewed. Under radioscopy, a self-expanding metal stent was placed endoscopically into the stenosis site of the stomach or the duodenum. Results All the metal stents were placed at the expected position. After operation the patients were given fluid diet at 1 day and soft diet at 3 days. No stent-related gastrointestinal perforation or hemorrhage was observed. Follow-up for 1~24 months in 21 patients found re-obstruction in only 2 patients and no migration of metal stents. Conclusions Self-expanding metal stent placement for malignant gastroduodenal obstruction is safe and effective.
