Clinical Outcomes of the Endoscopic Resection of Premalignant and Malignant Gastrointestinal Lesions

March 20, 2026 updated by: Kenneth Binmoeller, California Pacific Medical Center Research Institute
To evaluate clinical outcome for patients receiving treatment of suspected premalignant and malignant gastrointestinal lesions at Interventional Endoscopy Services. The primary outcome is curative endoscopic resection. Secondary outcomes include resection technique utilized, rates of en bloc resection and adverse event rates, including infection, bleeding, perforation and death, and one-year survival rates.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Technical success.
Time Frame: 1 day to 3 months
Technical success is defined as complete resection confirmed by the endoscopic absence of adenomatous tissue after inspection with high-definition white light and narrow-band imaging.
1 day to 3 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Short term recurrence rate
Time Frame: Less than 1 year
Freedom from recurrence on follow-up endoscopy with high definition white light and narrow band imaging and on mucosal biopsies of the endoscopic mucosal resection site
Less than 1 year
Long term recurrence rate
Time Frame: Greater than 1 year
Freedom from recurrence on follow-up endoscopy with high definition white light and narrow band imaging and on mucosal biopsies of the endoscopic mucosal resection site
Greater than 1 year
Adverse event rate
Time Frame: up to 1 month post procedure.
Adverse events include infection, bleeding, perforation and death.
up to 1 month post procedure.
Endoscopic en bloc resection rate
Time Frame: Immediate
Resection in 1 piece without fragmentation, along or extrinsic to the diathermic markings placed around the perimeter of the lesion before resection, without remnant abnormal tissue visible on HD white-light imaging or NBI
Immediate
