title: Subjective taste to polyethylene glycol is associated with efficacy of right colon preparation.
abstract: OBJECTIVE
  A prospective observational trial with preparations using polyethylene glycol (PEG) to compare patient compliance and adverse events according to individual subjective taste.
  
  
  METHODS
  A total of 299 outpatients (mean ± standard deviation [SD] 56.5 ± 13.8 years, 172 males) were recruited for our study. We assessed the efficacy of bowel preparation, subjective taste to their regimens, compliance and adverse events during the preparation.
  
  
  RESULTS
  We achieved adequate preparation in 267 (89.3%). A total of 124 patients (41.5%) had 'unacceptable taste' to their regimens. The patients with acceptable taste had better compliance than the patients with unacceptable taste (p = .009). The patients with unacceptable taste had more frequent adverse events such as nausea, vomiting and abdominal bloating than the patients with acceptable taste (all p < .001, Table 2). Patients with unacceptable taste (16.1%) had more frequent inadequate preparation in overall colon than patients with acceptable taste (6.9%, p = .011). There was a significant difference in the efficacy of preparation of right colon between the two groups (p = .004).
  
  
  CONCLUSIONS
  Subjective taste to PEG is associated with efficacy of right colon preparation. In addition, subjective taste to PEG is associated with compliance and adverse events.
