About this study
Official title: Outcomes of Endoscopic Resection of Mucosal and Submucosal Lesions in the Duodenum and Ampulla
This research project, 'Outcomes of endoscopic resection of mucosal and submucosal lesions in the duodenum and ampulla'. The research project is aiming to determine the most effective and safe way to remove such lesions.
Read the detailed description
Endoscopic resection (ER) of superficial lesions of the duodenum and ampulla is a safe and effective surgery sparing modality in experienced hands. It is often curative of dysplastic lesions and is associated with minimal complications and high patient acceptance (1-5). Westmead Hospital has accumulated a significant amount of experience in the removal of such lesions; however, there is limited research to document the long term outcomes of patients undergoing endoscopic resection.The purpose of this study is to evaluate the long-term outcomes of ER of superficial lesions of the duodenum and ampulla.
