Combination of Lactulose and Polyethylene Glycol Electrolytes Powder (PEG-ELS) for Bowel Preparation in Type II Diabetes Mellitus Patients

Overview

Compared to the general population, diabetic patients have a significantly higher rate of inadequate bowel preparation. The European Society of Gastrointestinal Endoscopy (ESGE) guideline recommends polyethylene glycol (PEG) as the preferred bowel-cleansing agent, but there is currently no standardized bowel preparation protocol specifically for diabetic patients. Previous studies have shown that oral lactulose-based regimens or adding lactulose to the standard PEG protocol can improve bowel preparation quality, reduce adverse effects such as abdominal pain, bloating, nausea, and vomiting, and have no impact on blood glucose levels in diabetic patients after consuming 20g or 30g of lactulose. Herein, a multicenter randomized controlled trial(RCT) has been designed to explore the efficacy and safety of lactulose combined with polyethylene glycol electrolyte solution (PEG-ELS) for bowel preparation in patients with type II diabetes mellitus.

Overall, 254 patients with type II diabetes mellitus will be enrolled. They will be randomly assigned at a ratio of 1:1 to the PEG group and lactulose +PEG group. The primary endpoint is the percentage of adequate bowel preparation. Secondary endpoints include the detection rates of polyps or adenomas and the incidence adverse reactions associated with bowel preparation (nausea, vomiting, abdominal pain, bloating, etc.).
