Comparison of covered and uncovered self-expandable stents in the treatment of malignant biliary obstruction.

[Comparison between covered and uncovered self-expandable metal stents in patients with malignant distal biliary obstruction].

Bridge to surgery in patients with obstructive colorectal cancer Comparison of covered and uncovered stents.

AIM Placement of self-expandable metallic stent has been used for bridge to surgery in the treatment of colorectal obstruction. Our aim was to compare technical success and complication rates of covered and uncovered inserted stents in colorectal malignant obstruction patients. MATERIAL OF STUDY A series of 24 obstruction colorectal cancer patients were selected and included in the study for ...

A prospective randomised study of "covered" versus "uncovered" diamond stents for the management of distal malignant biliary obstruction.

BACKGROUND AND AIM Covered self-expandable metal stents (EMS) were recently developed to overcome tumour ingrowth in conventional EMS. However, supporting evidence for the efficacy of covered EMS is lacking. PATIENTS AND METHODS We enrolled 112 patients with unresectable distal biliary malignancies. They were randomly assigned to polyurethane covered (n = 57) or original diamond stent (n = 55...

Partially covered metal stents have longer patency than uncovered and fully covered metal stents in the management of distal malignant biliary obstruction: a retrospective study

BACKGROUND Self-expandable metal stents (SEMSs) are widely used for malignant biliary obstructions. Nitinol-covered SEMSs have been developed to improve stent patency. Currently, SEMSs may be uncovered, partially covered, or fully covered; however, there is no consensus on the best stent type for the management of malignant distal biliary obstruction (MDBO). METHODS Patients with unresectable...

No benefit of covered vs uncovered self-expandable metal stents in patients with malignant distal biliary obstruction: a meta-analysis.

BACKGROUND & AIMS Self-expandable metal stents (SEMS) are used in patients with malignant distal biliary obstruction; trials that compared covered and uncovered SEMS reported different results because of heterogeneous designs and patient populations. These studies compared patency of uncovered SEMS and covered SEMS, along with rates of pancreatitis, cholecystitis, cholangitis, SEMS migration, b...
