Percutaneous stent placement for the treatment of malignant biliary obstruction: nitinol versus elgiloy stents

Abstract

ObjectiveThis study aimed to compare two self-expanding stents, a nitinol stent and an elgiloy stent, both placed percutaneously, in terms of their efficacy in palliating inoperable malignant biliary obstruction.Materials and MethodsWe retrospectively investigated 99 patients with unresectable malignant biliary obstruction treated with percutaneous placement of a self-expanding metallic stent at our institution between May 2007 and January 2010. Serum bilirubin and liver enzyme levels were measured before and 30 days after stenting. For all procedures using elgiloy or nitinol stents, stent occlusion and patient survival rates were calculated using Kaplan-Meyer analysis.ResultsAll of the patients showed clinical improvement after stent placement, with no difference between the two groups. In both groups, the occlusion-free survival rate was 67% at 30 days, 37% at 90 days, 25% at 180 days, and 10% at 360 days, with no significant difference in relation to the type of stent.ConclusionThe two stents evaluated showed comparable efficacy for the percutaneous treatment of unresectable biliary malignancy, with good clinical results.

Percutaneous transhepatic approach to endoscopic placement of a 10F plastic biliary stent: step-by-step description of a novel technique

“…The endoscopic placement of plastic biliary stents is a well-established technique for treating benign, malignant, or recurrent biliary obstructive disease (1,2) . Although the percutaneous transhepatic technique is a well-known means of inserting external drains and metallic biliary stents (1,(3)(4)(5)(6)(7) , there has been only one study providing a technical description of the percutaneous transhepatic insertion of a plastic biliary stent, and the authors of that study employed a two-stage approach (1) . To our knowledge, there have been no articles describing the technique in a single-stage approach and using a 10F biliary stent.…”

Percutaneous transhepatic cholangiobiopsy

“…The results of fine-needle aspiration biopsy (FNAB) of the biliary system are inferior to those of FNAB of other sites (2) . Therefore, other techniques for obtaining histological samples have been developed for use in the biliary tract (3)(4)(5)(6)(7)(8)(9)(10) .…”

What the radiologist should know about the role of interventional radiology in urology

“…Image-guided interventions performed by interventional radiologists have changed the management of various abdominal conditions, urologic conditions in particular ( 1 - 5 ) . The number of potential applications of such interventions is growing because of their minimally invasive nature, the minimal morbidity associated with the procedures, and the fact that their use can shorten hospital stays.…”
