ABSTRACT

Introduction. A colonoscopy is currently the gold standard for assessment of the colonic mucosa. Multiple studies have shown a high percentage of incomplete colonoscopies, defined as the inability to achieve cecal intubation and full review of the mucosa in approximately 10-20%. The diagnostic accuracy and therapeutic safety of colonoscopy depends in part, quality of preparation and cleaning of the colon. Objective. To describe the predictors of inadequate bowel preparation on colonoscopy. Material and methods. A retrospective, observational, descriptive and analytical study of colonoscopy in the Hospital Juárez de México during May 2014 May 2015 was conducted. Inclusion criteria were all cases with complete records and colonoscopies suspended by inadequate bowel preparation. The analysis of results was done with basic analytical and descriptive statistics with the χ² test using SPSS 2012 software. Results. 349 colonoscopies were performed, 237 they met inclusion criteria, of which 69 (29.1%) procedures were incomplete or suspended by inadequate bowel preparation. The average age was 51.1 years (range 13-90 years) with no statistically significant difference p › 0.05. 51% of patients with inadequate bowel preparation had any comorbidity, compared to 49% (p = 0.004). A history of abdominal surgery was present in 49 (72%) of the studies, while 20 (28%) of the studies had no previous surgeries. Studies with inadequate bowel preparation 61 (89%) of them were outpatients while 8 (11%) patients who were hospitalized. Regarding socioeconomic status, 58 (84%) of the studies had inadequate preparation low socioeconomic status, whereas only 11 (16%) had a high socioeconomic level. Conclusions. The percentage of incomplete colonoscopy is similar to the international literature. Prognostic factors associated are: previous surgery, comorbidity and low socioeconomic status. Proper bowel prep remains of vital importance to the technical success and diagnosis of colonic pathology.
