ABSTRACT

Objectives: to compare subjective tolerance and secondaryadverse events to bowel cleansing prior to colonoscopy with polyethyleneglycol (PEG) and sodium phosphate (NaP) in adult patientsand in those 65 or more years old.Material and methods: retrospective matched study, choosing140 patients among all of those who underwent colonoscopyfrom March 2004 to May 2005. We investigated the presence ofthe next adverse events during bowel preparation: Fever, low digestivebleeding, abdominal pain, perianal pain, nausea, vomiting,thirst, somnolence, agitation, tremor and convulsions. We consideredbad objective tolerance if the patient presented any one ofthese events. We also asked patients about subjective tolerance topreparation.Results: seventy patients prepared with PEG and seventywith NaP were included (69 women and 71 men, mean age 60,6± 14,8 years). There was no relationship between subjective toleranceor the presence of adverse events and bowel cleansing withany of the products in general population or in elderly patients (p= 0,09 and p = 0,45 in the elderly). However, patients preparedwith NaP showed more nausea than those who employed PEG (p< 0,009), overall women of 65 or more years old. There were nosevere adverse events in patients prepared with NaP. Elderlyshowed better tolerance than younger patients, and women worsttolerance than men, irrespective of the lavage preparation employed.Patients prepared with PEG unfinished bowel cleansingmore frequently than those with NaP. Cleanliness achieved withNaP was significantly better than that obtained with PEG.Conclusions: bowel cleansing prior to colonoscopy with NaPis as well tolerated, safe and effective as with PEG, even in elderlyhealthy patients, although it causes more nausea. Cleanliness with NaP is better than that achieved with PEG (AU)
