Effect of Single Dose of 2L PEG on Bowel Preparation in Average-risk Patients Undergoing Colonoscopy
Effect of Single Dose of 2L PEG on Bowel Preparation in Average-risk Patients
Adequate quality of bowel preparation(BP) is important for colonoscopy. Several guidelines recommend that split-dose of 4L PEG should be used as a standard regime for BP. However, the high-volume PEG still results in lower compliance to the regime and increased cost.
Some high risk factors for inadequate BP have been identified, including old age, constipation, diabetes, the use of narcotics and prior history of inadequate BP. For average-risk patients without the high risk factors, the procedure of BP could be easier. In the previous study, with the use of single dose of 2L PEG, more than 90% of average-risk patients achieved adequate BP. Here investigators hypothesized that compared with the standard split dose of 4L PEG, single dose of 2L PEG may be not inferior in BP quality while may be accompanied with better tolerability.

Armas e Intervenções
Grupo de Participantes / Braço |
Intervenção / Tratamento |
|---|---|
|
Experimental: Single dose of 2L PEG
2 L of PEG solution was used on the day of colonoscopy.
|
Patients at average risk for inadequate BP were given instructions for bowel preparation through phone call a day before scheduled colonoscopy.
Patients began to drink 2 L of PEG 4-6 hours before colonoscopy at a rate of 250 mL every 15 minutes.
|
|
Comparador Ativo: Split-dose of 4L PEG
Split-dose of 4l PEG was used before and on the day of colonoscopy
|
All patients at average risk for inadequate BP were given instructions for bowel preparation through phone call a day before scheduled colonoscopy.
the participants began to drink the first 2 L of PEG at 7:00-9:00 PM on the day before colonoscopy at a rate of 250 mL every 15 minutes.
On the day of the procedure, patients took the remaining 2 L 4-6 hours before colonoscopy.

Prazo |
|---|---|---|
|
Rate of adequate bowel preparation(defined as a total BostonBowel Preparation Score ≥6 with each segmental BBPS≥2)
Prazo: 1 year
|
The adequacy of bowel preparation is defined as Boston Bowel Preparation Scale (BBPS), a 4-point scoring system applied to each of 3 broad regions of the colon: the right side, the transverse section, and the left side.
They were summed to give the total BBPS score, which ranged from 0 to 9.The withdrawal procedure was recorded by vedios.
The BBPS and segmental scores in each segment were judged by one endoscopist who was familiar with the criteria of BBPS and blinded to group allocation.
