Dataset Information

A multicentre, prospective, randomized, controlled trial comparing EVARREST™ fibrin sealant patch to standard of care in controlling bleeding following elective hepatectomy: anatomic versus non-anatomic resection.

ABSTRACT:

Background

This multicentre, randomized clinical trial assessed the safety and effectiveness of the EVARREST™ Fibrin Sealant Patch (FP) in treating parenchymal bleeding following anatomic and non-anatomic liver resections.

Methods

One hundred and two patients were stratified according to the type of hepatic resection (anatomic/non-anatomic), and randomized (1:1) after identification of an appropriate bleeding site, to FP vs Standard of Care (SoC, manual compression ± topical haemostat). The primary endpoint was haemostasis at 4 min from bleeding site identification with no re-bleeding requiring re-treatment.

Results

The FP was superior in achieving haemostasis at 4 min (96%, 48/50) to SoC (46%, 24/52; p < 0.001). Stratification for resection type showed treatment differences for primary endpoint for anatomic (24/25 FP vs 13/23 SoC; p = 0.001) and non-anatomic liver resections (24/25FP vs 11/29 SoC; p < 0.001). Adverse events related to the study procedure were reported in 40/50 patients (80%) in the FP group and 43/52 patients (83%) in the SoC group. One (2%) adverse event (infected intra-abdominal fluid collection) was possibly related to study treatment.

Conclusion

This clinical trial confirms that the FP is safe and highly effective in controlling parenchymal bleeding following hepatectomy regardless of the type of resection. ClinicalTrials.gov NCT01993888.

Project description:IntroductionHaemostasis after liver resection may be difficult to achieve as a result of the presence of challenging bleeding, the anatomic landscape of the liver and the quality of tissue making up the hepatic parenchyma. The fibrin pad (FP) is a topical absorbable haemostat designed to be effective in a variety of tissues and across multiple bleeding intensities. This is the first clinical trial to evaluate the hemostat's safety and effectiveness in controlling bleeding during elective hepatic resection.MethodsThis prospective, randomized, controlled superiority trial enrolled 104 subjects undergoing elective hepatectomy in 5 countries. After parenchymal transection, subjects with an appropriately defined target bleeding site (TBS) were stratified according to the type of hepatic parenchyma and immediately randomized 1:1: FP versus Standard of Care (SoC). SoC comprised manual compression with the use of an approved topical absorbable haemostat. The primary endpoint was haemostasis at 4 min from identification of the TBS, with no re-bleeding requiring re-treatment prior to abdominal closure. Results were stratified for both normal and abnormal (steatosis or cirrhosis) hepatic parenchyma. All subjects were followed for 60 days post-operatively.ResultsThe intent-to-treat (ITT) analysis showed an overall treatment difference of 53.0% (P < 0.001), 82.5% (33/40 FP) versus 29.5% (13/44 SoC) in achieving haemostasis at 4 min with no re-bleeding requiring treatment up to wound closure. The per protocol analysis showed an overall treatment difference of 65.7% (P < 0.001), with 33/35 successes (94.3%) in the FP group and 12/42 in the SoC group (28.6%). The stratification results showed treatment differences between the normal parenchyma group, 63.6% (95.8% FP versus 32.3% SoC P < 0.001) and a larger difference of 72.7% in the abnormal parenchyma group (90.9% FP versus 18.2% SoC P = 0.0003). Post-operative intra-abdominal fluid collections were less frequent in the FP group (3.4% FP versus 13.3% SoC P = 0.059). There was no difference in the safety profile between the FP or SoC groups.ConclusionsThe FP is safe and effective when used as an adjunct to achieve haemostasis during hepatic surgery. The success rate of achieving haemostasis with a FP remained high compared with the SOC group, especially in steatotic or cirrhotic liver tissue where the control success rates diminish. In addition, FP treatment of hepatic parenchymal surfaces may reduce the risk of post-operative biliary and fluid collections.
