Feasibility of EUS-guided Biliary Drainage With a New-type of Eletrocautery LAMS for the Treatmentof Patients With Distal Malignant Biliary Obstruction (SPAZUS)

Distal malignant biliary obstruction results from different types of tumors including pancreatic cancer, biliary tract cancer (BTC), gallbladder cancer, and metastasis, which can lead to obstructive jaundice. Endoscopic retrograde cholangiopancreatography (ERCP) represents the gold standard for jaundice palliation in this setting of patients. However, surgically altered anatomy (i.e., Whipple intervention, Roux-en-Y gastric bypass, Billroth II surgery), periampullary diverticula, gastric outlet obstruction, and malignant obstruction of the lumen determine the failure of the procedure in about 5-10% of cases, requiring alternative methods of decompression. Percutaneous transhepatic biliary drainage (PTBD) and surgical bypass are well established alternatives in these patients, but associated with increased morbidity, longer length of hospital stay and higher costs, and patient discomfort.

In 2001 Giovannini et al. described the first EUS guided biliary drainage (EUS-BD) through a transduodenal access with a needle knife.

Subsequently, EUS-BD has considerably evolved thanks to the development of dedicated devices such as lumen apposing metal stents (LAMS), specifically designed for endoscopic ultrasound procedures. LAMS are made up of braided nitinol, that is fully covered with silicone to prevent tissue ingrowth, with wide flanges on both ends to provide anchorage.

Recently, LAMS have been incorporated into a delivery system with an electrocautery mounted on the tip (Hot Axios; Boston Scientific Corp.), which allows the device to be used directly to penetrate the target structure without the need to utilize a 19G needle, a guidewire, and a cystotome for prior dilation. This has been described for drainage of peri-pancreatic fluid collections, common bile duct (CBD), gallbladder, and for creation of gastro-jejuno anastomosis. The biliary drainage procedure performed with the Hot Axios sistem is a one step procedure that requires less or no need for accessory exchange and becomes faster, thus potentially decreasing the risk of complications.

The procedure has been described as safe and effective with a technical success of 98.2 %, clinical success of 96.4 %, and low rate of complications 7 % (duodenal perforations, bleeding and transient cholangitis). A systematic review and meta-analyses showed clinical and technical success rates of 87% and 95% respectively. Currently, the EUS-BD is indicated as a rescue therapy for jaundice palliation after ERCP failure.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Sampling Method

Non-Probability Sample

Study Population

This is an observational multicentric prospective study coordinated by Dr. Benedetto Mangiavillano, Gastroenterology and Gastrointestinal Endoscopy Unit, Humanitas Mater Domini, Castellanza (VA), Italy. Data from consecutive patients with jaundice caused by distal malignant biliary obstruction will be evaluated and, if eligible and agreed to participate, will be recorded in an electronic register. Patients will be followed until death or for at least 6 months

Description

Inclusion Criteria:

  • Age ≥18 years
  • Patients with distal malignant biliary obstruction
  • Dilated common bile duct (>15 mm diameter) at either abdominal ultrasound, computed tomography, magnetic resonance or EUS or accessible gallbladder from the duodenum or from the stomach for the drainage
  • Agree to receive follow up phone calls
  • Able to provide written informed consent

Exclusion Criteria:

  • Coagulation and/or platelets hereditary disorders and/or INR>1.5, PLT<50,000
  • Use of anticoagulants that cannot be discontinued
  • Pregnant women
  • Inability to sign the informed consent

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
