The PEG-coated patch, alone or with fibrin sealant, demonstrated comparable efficacy in preventing CSF leak compared to multiple product combinations. The study does not demonstrate superiority, but shows a reassuring safety profile and similar rates of secondary outcomes, including pseudomeningocele, hospital readmissions, surgical site infections and adverse events, in both groups. These findings support the PEG-coated patch as a safe dural sealing option in elective non-traumatic posterior fossa surgery, while potential workflow or economic advantages remain to be formally evaluated in future studies.
