GOMEZ, Martín; BASTIDAS-RIASCOS, Melissa; RUIZ-MORALES, Óscar Fernando y TOBAR-MARCILLO, Marco. Factors Associated with Poor Colonoscopy Preparation. Rev. colomb. Gastroenterol. [online]. 2023, vol.38, n.3, pp.311-319. Epub 17-Ene-2024. ISSN 0120-9957. https://doi.org/10.22516/25007440.1001.
Introduction:
Good bowel preparation is essential for a quality colonoscopy. Thus, evaluating the risk factors associated with poor preparation is necessary. This problem has not been widely addressed in Colombia.
Aim:
To identify the factors associated with poor intestinal preparation.
Materials and methods:
Observational, analytical, cross-sectional, multicenter study in patients > 18 years of age who underwent colonoscopy and attended gastroenterology services between January and June 2020 in Bogotá. A Boston scale > 6 was defined as good preparation, and a Boston scale ≤ 6 was defined as poor preparation.
Results:
265 patients were included, of whom 205 (77.4%) were well prepared and 60 (22.6%) had inadequate preparation. Factors associated with poor bowel preparation were age older than 60 years (odds ratio [OR]: 1.359; 95% confidence interval [CI]: 1.059-1.745; p = 0.026); male sex (OR: 1.573; 95% CI: 1.128-2.194; p = 0.012); obesity (BMI > 30 kg/m2; OR: 2.539; 95% CI: 1.388-4.645; p = 0.002); constipation (OR: 1.924; 95% CI: 1.154-3.208; p = 0.014); the use of antidepressants (OR: 2.897; 95% CI: 1.199-6.997; p = 0.014) and calcium antagonists (OR: 2.445; 95% CI: 1.292-4.630; p = 0.005), and having abdominopelvic surgeries (OR: 1.325 95% CI: 1.042-1.684, p = 0.034). Regarding the procedure, there was less polyp detection per patient (p = 0.04) and less minute (p = 0.020) and flat (p = 0.047) polyp detection in the poor bowel preparation group.
Conclusions:
This is the first study in Colombia in which the factors associated with poor intestinal preparation are described and include variables not explored in other studies. The results found are similar to those reported in the literature. These studies should be promoted with more patients, establishing a score for predicting poor preparation.
