Does biphasic PFA prevent chronic histopathologic esophageal changes compared to RFA in a porcine model of esophageal injury?
In a porcine model, biphasic PFA appears safer for the esophagus than RFA, causing no chronic histopathologic changes.
In this novel porcine model of esophageal injury, biphasic PFA induced no chronic histopathologic esophageal changes, while RFA demonstrated a spectrum of esophageal lesions including fistula and deep esophageal ulcers and abscesses.
Koruth et al. (Fri,) studied this question.
