NCT06722209

Brief Summary

The aim of this study was to investigate the effect of different bowel preparation protocols applied on the same day on patients' compliance, tolerance and bowel cleansing before colonoscopy. Hypotheses of the Study : Same-day administration of bowel preparation before colonoscopy; H1.1: There is a significant difference between the bowel preparation protocol with polyethylene glycol (Protocol I) and the protocol with sodium phosphate (Protocol II) in bowel preparation score scores H1.2: There is a significant difference between the compliance levels of the patients who underwent a bowel preparation protocol containing polyethylene glycol (Protocol I) and a protocol containing sodium phosphate (Protocol II) H1.3: There is a significant difference between the tolerance of the patients who underwent a bowel preparation protocol containing polyethylene glycol (Protocol I) and a protocol containing sodium phosphate (Protocol II) In patients in Protocol I and II groups, data will be collected one day before the procedure with the Descriptive Characteristics Form and the procedure will be explained face to face. After the procedure, bowel preparation score during colonoscopy and compliance and tolerance to the bowel preparation protocol will be evaluated from the patients in both groups.

Outcome Measures

Primary Outcomes (1)

  • Compliance and Tolerance to the Bowel Preparation Protocol

    The Bowel Preparation Protocol Compliance and Tolerance Assessment Form will assess this primary outcome. This form assesses tolerance to the bowel preparation protocol; abdominal pain, nausea, vomiting, Abdominal distension -gas,thirst , headache, weakness and fatigue and intolerance to the solution. The rate of patients experiencing variables including Compliance and Tolerance to the Bowel Preparation Protocol will be calculated.

    The patients were interviewed 30-60 dk minutes after the procedure was completed.

Secondary Outcomes (1)

  • Bowel cleansing quality level

    BBPS will be assessed by the surgeon during colonoscopy.

Study Arms (2)
