Conditions
Bile Leakage
Interventions
Drug: "white" test" (= the administration of SMOFlipid retrograde through the cystic duct)
Registration Number
NCT04523701
Lead Sponsor
Giulia Manzini
Brief Summary

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.

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.

GroupInterventionDescription
Experimental Intervention (treatment)"white" test" (= the administration of SMOFlipid retrograde through the cystic duct)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.
Primary Outcome Measures
NameTimeMethod
rate of postoperative bile leakagewithin 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.

Secondary Outcome Measures

Severity of the bile leakage (Grade A, B or C according to the definition by Koch et al).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.
