Treatment of ampullary adenoma with intraductal extension of 20 mm or less

Ampullary adenoma presenting with intraductal extension up to 20 mm defines a clinically distinct subset that requires careful management in an expert setting. The presence of intraductal spread directly influences the choice between endoscopic and surgical approaches.

Clinical scenario Ampullary adenoma with intraductal extension of 20 mm or less. According to ESGE guidance, expert centers may employ complementary endoscopic techniques alongside temporary biliary stenting for lesions within this range of intraductal involvement.

Management approach For ampullary adenoma with intraductal involvement, a surgical approach — specifically transduodenal ampullectomy — remains an accepted and guideline-supported option in defined circumstances. The full structured protocol specifies the exact indications, sequencing, and supporting evidence. Complete regimen and decision criteria available via the link below.

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.

However, surgical transduodenal ampullectomy is still an acceptable option for ampullary adenoma, being preferred to endoscopic papillectomy in the following settings: intraductal involvement; impossibility of performing endoscopic papillectomy for technical reasons (e. g. diverticulum, size > 4 cm); incomplete resection after endoscopic papillectomy with positive margins; and local recurrence not treatable by endoscopy.
