Diagnostic Role of the "White Test" With Lipidic Solution in the Early Intraoperative Identification of Open Bile Ducts for the Prevention of Bile Leakage After Liver Resection- A Randomized Controlled Multicentric Superiority Trial- The BiLe-Trial (Bile Leakage Trial)

Bile leakage (BL) is the most frequent complication after liver resection. This study is to investigate the role of intraoperative administration of SMOFlipid 20% (fat emulsion which allows intraoperative identification of open bile ducts at the liver resection surface when it is administered retrograde through the cystic duct) in terms of prevention of postoperative BL within 30 days after surgery.

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.

Detailed Description

Bile leakage (BL) is the most frequent complication after liver resection leading to the need of interventional drainage, endoscopic retrograde cholangio pancreatography (ERCP) or even reoperation. Strategies leading to a reduction of the rate of this complication are valuable. SMOFlipid 20% is a fat emulsion which is primary indicated for parenteral nutrition. Because of its fatty content this solution is white. This allows the clear intraoperative identification of open bile ducts at the liver resection surface when it is administered retrograde through the cystic duct. Consequently, open bile ducts can be sutured preventing the postoperative development of BL. If the rate of bile leakages can be reduced, resources for interventions and relaparotomy will be saved. This study is to investigate intraoperative administration of SMOFlipid 20% in terms of prevention of BL within 30 days after surgery.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Patients who will receive an anatomical resection of two or more liver segments for any reason with simultaneous cholecystectomy in elective Setting
  • Patients who will receive an anatomical resection of two or more liver segments for any reason which already had a cholecystectomy if intraoperatively the cystic stump can be identified and opened
  • Ability of subject to understand character and individual consequences of the clinical Trial
  • Informed consent documented by signature

Exclusion Criteria:

  • Previous cholecystectomy if intraoperative it is not possible to identify the cystic stump
  • Intraoperative hepatico-jejunostomy
  • Hypersensitivity to fish-, egg-, soybean or peanut protein or to any of the active ingredients or excipients
  • Immunosuppression, pregnancy
  • Emergency liver resection because of traumatic liver rupture
  • Enrolment of the investigator, his/her family members, employees and other dependent persons

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Experimental Intervention (treatment)

Open bile ducts are identified by visual control of the liver resection surface combined with the direct injection in the cystic stump of 20-40ml of SMOFlipid 20% Fresenius Kabi Canada Ltd.; authorization number: 57231 (Swissmedic).

SMOFlipid is a white oily emulsion containing soya oil and medium chain triglycerides as main active components, normally used as parenteral nutrition as complement for essential fat acids supplementation. In this study the "white" test (= the administration of SMOFlipid retrograde through the cystic duct) is made by injection of one or two 20cc syringes full of lipidic solution (SMOFlipid 20%) in the cystic stump, directing the flow to the intrahepatic ducts. Residual fat emulsion is washed out from the biliary tract by a low pressure infusion of 20 to 50 ml of saline solution.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
rate of postoperative bile leakage
Time Frame: within 30 days postoperative
Comparison of the rate of postoperative bile leakage in the control and in the intervention group. This is a binary endpoint defined by the presence or absence of the bile leakage (yes or no). Bile leakage is defined as bilirubin concentration in the drain fluid at least 3 times the serum bilirubin concentration on or after postoperative day 3.
within 30 days postoperative

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Severity of the bile leakage (Grade A, B or C according to the definition by Koch et al).
Time Frame: within 30 days postoperative
The severity of bile leakage is classified according to its impact on patients´ clinical management. Grade A bile leakage causes no change in patients' clinical management. A Grade B bile leakage requires active therapeutic intervention but is manageable without relaparotomy, whereas in Grade C bile leakage relaparotomy is required.
