Is this trial a fit for you?

Likely a good fit

Adults over 18 with mucosal or submucosal duodenal or ampullary lesions who underwent endoscopic resection at Westmead Hospital between 2010 and 2025.

Probably not a fit

Patients with non-resectable disease, lesions outside the duodenum/ampulla, or those lacking long-term follow-up data may not benefit from the findings.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a retrospective study analyzing endoscopic resections of mucosal and submucosal lesions in the duodenum and ampulla performed at Westmead Hospital over a 15-year period. It will examine complete resection rates, recurrence patterns, and long-term outcomes including complications and mortality related to malignancy. The objective is to better define the role of endoscopic therapy for these heterogeneous lesions and to identify factors that predict long-term success. Data will come from medical records of eligible adults treated between January 2010 and March 2025. The findings may help guide future patient selection and follow-up strategies.

Why it matters

Potential benefit: If successful, the study could clarify which patients benefit most from endoscopic removal and inform follow-up practices to reduce recurrence and complications.

How similar studies have gone: Prior experiences with endoscopic management of duodenal/ampullary lesions show variable long-term outcomes, making this retrospective analysis valuable but results may be heterogeneous.
