PREDICTIVE FACTORS FOR AN ADEQUATE BOWEL PREPARATION. A PROSPECTIVE ANALYSIS
Publication History
Publication Date:
18 March 2019 (online)
Aims:
To determine predictive factors to achieve an adequate bowel preparation.
Methods:
Prospective register of consecutive colonoscopies. February 2014 -July 2018. Variables: demographic data, indication for colonoscopy, type of bowel cleansing solution and administration regimen, colon length and Boston bowel preparation scale (BBPs). Patients with colon resection and incomplete colonoscopies were excluded.
Results:
We included 7795 patients. Age: 58.8 ± 13.3y; 51.6% women. The diagnostic colonoscopies were more frequents: 66.9%. The 95.4% of patients fulfilled the administration regimen, 64.1% with sodium-picosulfate (SP/MC) and 35.9% with PEG3350/ascorbic acid. The most of patient drank cleansing solution at the same day using “split dose”: 87.1%. We defined as a long colon the 11.8% of colonoscopies and according to BBPs (score ≥2 in each segment), the 86,7% were adequately prepared. In a multivariate analysis the fulfillment of the administration regimen: OR = 3.57; 95% IC: 2.47 – 5.15, age < 60y: OR = 1.91; 95% IC: 1.64 – 2.24, the intake of cleansing solution at the same day using “split dose”: OR = 1.84; 95% IC: 1.45 – 2.32, the female gender: OR = 1.33; 95% IC: 1.14 – 1.55, the SP/MC use: OR = 1.33; 95% IC: 1.14 – 1.56 and the screening colonoscopy: OR = 1.26; 95% IC: 1.07 – 1.47 were associated to adequate bowel preparation.
Conclusions:
Female < 60 years old who intake SP/MC solution at the same day in “split dose” in whom the indication for colonoscopy was CRC screening achieve an adequate bowel preparation. Therefore in those patients in whom these features are not identified we recommend a more intensive preparation strategy.
