Optimizing colonoscopy with abdominal compression devices: an updated meta-analysis of randomized controlled trials

Area of Science:

• Gastroenterology
• Medical Devices
• Clinical Trials

Background:

• Colonoscopy is crucial for colorectal cancer screening but can be uncomfortable, especially for older patients or those with diverticular disease.
• Abdominal compression devices (ACDs) are used to potentially alleviate discomfort and improve procedural efficiency during colonoscopy.

Purpose of the Study:

• To systematically review and meta-analyze the impact of abdominal compression devices (ACDs) on patient comfort and procedural efficiency during colonoscopy.

Main Methods:

• A comprehensive literature search was conducted across multiple databases (PubMed, Web of Science, Scopus, Cochrane Central, Embase) up to April 2025.
• Included 16 randomized controlled trials with 3098 participants.
• Risk of bias was assessed using the Cochrane ROB2 tool; data analysis was performed using R version 4.2.2.

Main Results:

• ACDs significantly reduced cecal intubation time (MD: -2.20, P=0.009) and the need for manual pressure (RR: 0.54, P=0.003) and patient repositioning (RR: 0.55, P<0.001).
• ACDs were associated with lower visual analog scale pain scores, indicating improved patient satisfaction.
• No significant differences were observed in complete colonoscopy rates or cecal intubation lengths.

Conclusions:

• Abdominal compression devices optimize colonoscopy procedures, enhancing patient comfort and reducing staff workload.
• Integration of ACDs into routine practice is recommended.
• Future research should focus on standardizing ACD application and evaluating long-term outcomes.
