The purpose of this study is to evaluate the long-term outcomes of Endoscopic Resection (ER) of superficial lesions of the Upper Gastrointestinal Tract(UGIT)

Endoscopic resection (ER) of superficial lesions of the upper gastrointestinal tract 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 UGIT.

Inclusion Criteria:

• UGIT lesion > 10mm
• Lesion limited to the mucosal and/or submucosal layer (T1 lesion)
• Aged 18 years or older

Exclusion Criteria:

• Lesion less than 10mm
• Gastric lesion involves the muscularis propria (T2 lesion) on other staging modalities such as endoscopic ultrasonography (EUS)
• Aged younger than 18 years

Patients who have Upper Gastrointestinal Tract adenomas which are amendable to Endoscopic Mucosal Resection
