Background and Study Aims: Various types of self-expandable metal stents have been introduced for biliary drainage in patients with malignant jaundice, showing prolonged patency compared with plastic endoprostheses. However, there has only been prolonged experience with a meaningful number of patients using the Wallstent. We evaluated the Diamond stent, a self-expanding uncoated biliary metal stent, in a prospective uncontrolled multicenter setting.

Patients and Methods: The eligibility criterion was obstructive jaundice due to inoperable malignant disease. Between August 1995 and January 2000, 126 patients, who received a total of 134 Diamond stents in four European centers, were followed prospectively.

Results: Technical and clinical success rates were 96 % and 98 %, respectively. No major procedure-related complications occurred. The 30-day mortality rate was 13 %. Stent occlusion occurred in 28 patients (22 %). Overall median stent patency was 477 days; overall median survival was 173 days. Stent occlusion, confirmed by endoscopic retrograde cholangiopancreatography, was successfully treated with plastic stents in all patients. Cost analysis revealed estimated costs of €3440 per patient for palliative treatment with the Diamond stent.

Conclusions: The Diamond stent compares favorably with other biliary metal stents for patients requiring biliary drainage of malignant jaundice.
