The study compared the efficacy and tolerability of two different low-volume split-dose polyethylene glycol electrolytes solution (PEG-ELS) bowel preparation for morning colonoscopy. Methods. A total of 120 patients were randomized to receive either the control group (n\u2009=\u200964) or the experimental group (n\u2009=\u200965). Patients in the control group adopted the low-volume split-dose regimen one, and patients in the experimental group adopted the low-volume split-dose regimen two. Those randomized to regimen one were instructed to take 0.75\u2009L PEG two hours after dinner the day before the colonoscopy and 1.5\u2009L PEG 4 hours before the colonoscopy. Patients assigned to regimen two were invited to consume 1.5\u2009L PEG two hours after dinner the day before the colonoscopy and 0.75\u2009L PEG 4 hours before the colonoscopy. The quality of bowel preparation, rated according to a Boston Bowel Preparation Scale (BBPS), represented the primary outcome measure. Tolerability, satisfaction, and lesions detection rated were secondary outcomes. Results. There was no significant difference between the transverse colon and right colon scores between the two groups (<jats:inline-formula>\n                     <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mi>P<\/a:mi>\n                        <a:mo>&gt;<\/a:mo>\n                        <a:mn>0.05<\/a:mn>\n                     <\/a:math>\n                  <\/jats:inline-formula>).
