About this study

Official title: Partially Covered Metal Stents Efficacy in the Biliary Drainage of Malignant Extra-hepatic Biliary Obstruction, a Multicentric Randomized Trial

Malignant obstructions of the bile duct are not rare. The most common and accepted method for biliary drainage is endoscopic stent placement. There are three types of metal stents: fully covered (FC), partially covered (PC) and uncovered (U). PC-SEMS have been recently introduced and compared to FC-SEMS they seem to have a lower risk of migration, although data in the literature are discordant. Therefore the investigators will randomize the participants with biliary obstruction in 2 groups according to the type of stent used: PC-SEMS or U-SEMS. After metallic biliary stent insertion, enrolled patients will be followed for 12 months.

Read the detailed description

Malignant obstructions of the bile duct are generally caused by: adenocarcinoma of the Vater ampulla, pancreas head cancer, cholangiocarcinoma and external compression secondary to lymph node (LN) metastasis. The management of jaundice and cholangitis, as a result of bile stenosis, is crucial in this group of patients. The most common and accepted method for biliary drainage is endoscopic stent placement with plastic stents or self-expandable metal stents (SEMS). In recent times, the use of SEMS has become more common as it provides longer times of patency and a reduced risk of adverse events such as cholangitic episodes. There are three types of metal stents: fully covered (FC), partially covered (PC) and uncovered (U). PC-SEMS have been recently introduced and compared to FC-SEMS they seem to have a lower risk of migration, however different randomized and non-randomized studies have compared the outcome of U-SEMS vs FC-SEMS with between uncovered and covered stents have produced different results regarding the cumulative patency of stents and endoscopic re-intervention rates. To date, there are few and discordant prospective data on the outcomes of PC-SEMS use in malignant biliary obstructions.

Therefore, the investigators will randomize the participants with biliary obstruction in 2 groups according to the type of stent used: PC-SEMS or U-SEMS (T0 timing).

Then the participants will be followed for total period of 12 months. 2 different timings of follow-up will be considered:

  • T1: it will start after stent insertion. The biliary drainage will be considered effective, according to the European guidelines, when the bilirubin values will be < or = 2 mg/dl for a period of at least 6 weeks if the initial bilirubin values were higher than 10 mg/dl or 3 weeks if at the beginning were lower than 10 mg/dl; After this first phase, all the enrolled patients will be divided in 2 groups according to their "fitness" for chemiotherapy: FIT and UNFIT Group.

FIT group: blood test (including total bilirubin, gamma-GT) will be done for follow-up study once every three months.

UNFIT Group: blood test (including total bilirubin, gamma-GT) will be done for follow-up study after 3, 9 and 12 months.

Study groupRoleWhat they receive
Partially Covered Metal Stent ArmActive comparatorThe patients who had extra-hepatic malignant biliary obstruction will be enrolled in our study. Enrolled patient will be randomized to two group (uncovered metallic stent vs. partially covered metallic stent). After metallic biliary stent insertion, enrolled patients will be followed until bilirubin values will be under 2 mg/dl.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Re-intervention rate

    Evaluation in both arms of the re-intervention rate considered as any procedure needed for a new drainage of the biliary tree, endoscopic or percutaneous, to replace a dysfunctional stent.

    Measured: 12 months

Secondary outcomes (1)
  1. Evaluation of patency, migration and adverse events rate

    evaluation of patency, migration and adverse events rate for each arm

    Measured: 12 months
