Abstract

Objectives: To compare the efficacy of two liter polyethylene glycol with four liter polyethylene glycol solution for bowel
cleansing for colonoscopy.
Material & Methods: This study was conducted in the Department of Gastroenterology, MTI, Lady Reading Hospital,
Peshawar, Pakistan comprising of 458 patients. These patients were randomized to 2 groups A and B by lottery method
so that each group contains 229 patients. Group A received 2 liters of PEG solution for bowel cleansing while group
B received 4 liters of PEG solution. Patient’s bowel preparation was evaluated to Boston Bowel preparation score by
experienced endoscopists who would not know the regimen used for bowel cleansing.
Results: Our study shows that in group A mean age was 34 years ± 11.273 SD while in Group B mean age was 32
years ± 10.182 SD. In Group A 42% patients were male and 58% patients were female. Where as in Group B 45%
patients were male and 55% patients were female. Two liter polyethylene glycol was effective in 80% patients while four
liter polyethylene glycol solution was effective in 85% patients.
Conlcusion: There is no significant difference in two liter Polyethylene Glycol solution and 4 liter solution. Hence two
liter Polyethylene Glycol solution can be used for the for bowel cleansing for colonoscopy instead of 4 liter solution.

Keywords: Polyethylene glycol, colonoscopy, bowel cleansing.
