摘要

Purpose

This study aimed to evaluate the association between cholecystectomy and colonic bubble formation during colonoscopy,

Methods

A single-center retrospective cohort study was conducted at Staten Island University Hospital. Researchers reviewed 348 colonoscopy reports, comparing patients with (n = 56) and without (n = 292) a history of cholecystectomy. Colonic bubble formation was assessed using a 0–3 scale (0 = no bubbles, 3 = severe bubbles). Secondary endpoints included polyp and adenoma detection, withdrawal and procedure times, bowel preparation quality, and repeat procedures. Statistical analysis included t-tests, Mann–Whitney U tests, and χ2 tests.

Results

Patients with prior cholecystectomy had significantly higher incidence of severe bubble formation (score 3; 28.6% vs. 12%, p = 0.001), longer withdrawal times (18 ± 8 vs. 15 ± 5 min, p = 0.024), and increased need for repeat colonoscopies (10.7% vs. 2.1%, p = 0.001). No significant differences were found in adenoma detection, polyp detection, or bowel preparation quality between the two groups.

Conclusion

Cholecystectomy is associated with increased colonic bubble formation during colonoscopy, leading to longer withdrawal times and higher rates of repeat procedures. While this study did not find a difference in adenoma detection rates, the impaired visualization caused by bubbles may necessitate tailored bowel preparation strategies for patients with a history of cholecystectomy to optimize colonoscopy effectiveness.
