Endocuff-Assisted versus Cap-Assisted Colonoscopy Performed by Trainees: A Retrospective Study

Area of Science:

• Gastroenterology
• Endoscopy
• Medical Devices

Background:

• Trainee adenoma detection rate (ADR) in screening colonoscopies is typically lower than expert rates.
• Cap-assisted colonoscopy (CAC) is known to improve trainee ADR.
• Endocuff, a novel endoscopic cap, shows promise for adenoma detection.

Purpose of the Study:

• To compare the efficacy of Endocuff-assisted colonoscopy (EAC) versus cap-assisted colonoscopy (CAC) for adenoma detection by trainees.
• To evaluate adenoma detection rate (ADR) and mean adenomas per patient (MAP) between EAC and CAC in a trainee setting.

Main Methods:

• Single-center, retrospective study of 305 patients undergoing EAC or CAC by three trainees.
• Evaluation of ADR, MAP, cecal intubation rate, intubation time, and complications.
• Data collected between January and December 2018.

Main Results:

• EAC group showed significantly higher ADR (54.3%) than CAC group (37.3%, p=0.019).
• Mean adenomas per patient (MAP) was significantly higher in EAC group (1.36) versus CAC group (0.74, p=0.003).
• No significant differences in cecal intubation rates, intubation times, or major complications were observed.

Conclusions:

• Endocuff-assisted colonoscopy (EAC) demonstrates superior adenoma detection compared to cap-assisted colonoscopy (CAC) when performed by trainees.
• EAC may enhance trainee performance in colonoscopic screening for adenomas.
