Intraductal Adenoma

Clinical Challenge

  • Endobiliary dysplasia may persist in 30%, post papillectomy1
  • Surgery has been standard management consideration,radiofrequency ablation may offer an additional treatment option

Clinical Goal

Management of ductal dysplasia post papillectomy

Literature Highlights

Prospective, multi-center study has shown1

  • Residual neoplasia at 6mo and 12 mo. of 15% and 30%
  • No major adverse events
    • 15% mild pancreatitis
    • 5% cholangitis
    • 10% mild biliary stricture
  • Another study6showed mean number of ablations sessions of 1 per patient (range 1-5). Those with high-grade dysplasiareceived a mean of 2.6 + 1.5 (p=0.011)


ESGE suggests the use, in expert centers, of complementary techniques (thermal ablation by cystotome, or radiofrequency ablation [RFA]) with temporary biliary stenting, for ampullary adenoma with ≤20-mm intraductal extension.
