The Yield of Artificial Intelligence (GI Genius) in Lynch Syndrome - A Randomized Tandem-colonoscopy Trial

April 15, 2026 updated by: Sheba Medical Center

We aim to investigate the incremental detection rate of polyps using AI- assisted colonoscopy compared with high-definition white-light endoscopy (HD-WLE).

We will conduct a single-center randomized tandem colonoscopy trial of patients with Lynch syndrome with and without AI. Patients will undergo tandem colonoscopy, the second colonoscopy with either HD-WLE or an AI- assisted device.

Detailed Description

We will include patients with a known pathogenic variant (PV) / likely PV in one of the MMR genes, who are undergoing endoscopic screening and surveillance in our institute. Patients will undergo a first colonoscopy with HD-WLE, and will be randomized at 1:1 ratio to undergo a second colonoscopy with either HD-WLE or an AI- assisted device. All visualized polyps will be removed and size, histology and numbers of polyps detected on each exam will be recorded. We will evaluate the adenoma detection rate and polyp detection rate in each arm and the number of adenomas / polyps in each arm.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
adenoma incremental detection rate
Time Frame: From the start of the first colonoscopy until the end of the second colonoscopy, performed on the day of enrollment (both colonoscopies performed consecutively on the same day).]
per lesion analysis, the incremental detection rate will be calculated, defined as the number of lesions detected during the second colonoscopy divided by the total number of lesions detected during first and second colonoscopy combined.
From the start of the first colonoscopy until the end of the second colonoscopy, performed on the day of enrollment (both colonoscopies performed consecutively on the same day).]

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
incremental detection rate for advanced neoplasia and any polyp
Time Frame: From the start of the first colonoscopy until the end of the second colonoscopy, performed on the day of enrollment (both colonoscopies performed consecutively on the same day).]
per lesion analysis, the incremental detection rate for advance neoplasia and any polyp. In the per patient analysis, the increment in adenoma detection rate and any polyp detection rate.
From the start of the first colonoscopy until the end of the second colonoscopy, performed on the day of enrollment (both colonoscopies performed consecutively on the same day).]
The increment in adenoma detection rate / polyp detection rate
Time Frame: From the start of the first colonoscopy until the end of the second colonoscopy, performed on the day of enrollment (both colonoscopies performed consecutively on the same day).]
per lesion analysis, the incremental detection rate for advance neoplasia and any polyp. In the per patient analysis, the increment in adenoma detection rate and any polyp detection rate.
From the start of the first colonoscopy until the end of the second colonoscopy, performed on the day of enrollment (both colonoscopies performed consecutively on the same day).]
