New Methods: Clinical EndoscopyPalliation in patients with malignant gastric outlet obstruction with a newly designed enteral stent: a multicenter study
Section snippets
Patients
We conducted a multicenter study of patients undergoing enteral stent placement by using a newly designed enteral stent for unresectable malignant GOO. Patients were enrolled from January 2005 to August 2006 at 3 referral hospitals: Toho University Ohashi Medical Center, Tokyo; the University of Tokyo Hospital, Tokyo; and the National Hospital Organization Kyoto Medical Center, Kyoto. Inclusion criteria were documented malignancy, pyloroduodenal obstruction confirmed by radiography or
Results
A total of 37 consecutive patients (median age, 67 years; quartile 64-75.5 years) were enrolled from January 2005 to August 2006 (Table 1). The etiology of GOO was pancreatic, gastric, gallbladder, metastatic, or other malignancies. The site of obstruction was the duodenum in 20 patients, the pylorus in 14, the efferent limb after Child's operation in 2, and gastroduodenostomy after distal gastrectomy with Billroth I in 1. Of 20 patients with duodenal obstruction, 2 had undergone a distal
Discussion
The present study is the first to analyze the clinical experience with a newly designed enteral stent, the Niti-S enteral colonic stent and introducer. Results showed that this new woven stent, with higher flexibility and less foreshortening, offers comparable clinical outcomes to existing stents and a lower frequency of complications, including migration.
Malignant GOO remains a challenging clinical condition. The main goal of the treatment is amelioration of the obstructive symptoms and the

2020, Digestive and Liver DiseaseCitation Excerpt :Over the past two decades, endoscopic duodenal self-expandable metal stents (SEMSs) have changed the management of MGOO and improved the quality of life of patients. The effectiveness of SEMSs has been shown by several studies, and SEMSs are associated with a relatively low severe complication rate ranging from 0% to 23% [1–15]. Historically, surgical treatment by open or laparoscopic surgical bypass has been compared to endoscopic treatment.
