Cap cuff-assisted colonoscopy versus standard colonoscopy for adenoma detection: a randomized back-to-back study

Area of Science:

• Gastroenterology
• Endoscopy
• Cancer Prevention

Background:

• EndoCuff is a device designed to enhance mucosal visualization during colonoscopy.
• Previous studies indicated EndoCuff improves adenoma detection rate (ADR).

Purpose of the Study:

• To compare the adenoma detection rate (ADR) between EndoCuff-assisted colonoscopies (EAC) and standard colonoscopies.
• To evaluate the impact of EndoCuff on adenoma detection in a randomized back-to-back trial.

Main Methods:

• A single-center, randomized crossover study involving adult patients undergoing colonoscopy.
• Participants underwent back-to-back standard and EndoCuff-assisted colonoscopies by the same endoscopist.
• Adenomas were identified by histology after polyp excision.

Main Results:

• EndoCuff-assisted colonoscopies (EAC) showed a higher ADR (29.6% vs. 26.3%) and detected more adenomas (176 vs. 129) compared to standard colonoscopies.
• EAC particularly improved detection of small adenomas (<5 mm) in both the left and right colon.
• A small percentage of patients experienced minor mucosal erosions (2.5%) with EndoCuff use.

Conclusions:

• EndoCuff use increases the detection of adenomas, especially small ones, in the colon.
• This leads to a higher ADR and facilitates more precise surveillance program planning.
• The findings support EndoCuff as a tool to improve colonoscopy effectiveness.
