Description
Inclusion Criteria:
- Voluntarily participate and sign informed consent;
- Scheduling screening, surveillance, and diagnostic colonoscopy;
- Necessary body fluid and blood electrolyte balance (the test values of potassium, sodium, chlorine, calcium and magnesium in blood biochemistry during screening period should not exceed 10% of the normal range).
Exclusion Criteria:
- Subjects who used drugs that affect gastrointestinal dynamics, affect kidney function, or increase the risk of fluid retention or electrolyte disorders within 7 days before the start of the trial;
- Subjects with serious cardiac and cerebrovascular diseases, bronchial and lung diseases, suffering from metabolic disease or endocrine disease, abnormal blood clotting mechanism, malignant tumor, electrolyte abnormalities, epilepsy, Renal or liver dysfunction;
- Subjects with confirmed or suspected gastrointestinal obstruction, gastric retention, gastroparesis, gastric emptying disorder or acute gastrointestinal bleeding;
- Subjects with acute severe colitis (such as active severe inflammatory bowel disease, acute bacterial dysentery, diverticulitis, etc.);
- Subjects with a history of major gastrointestinal surgery (e.g. gastric bypass, gastric septal surgery, colostomy, colectomy, etc.);
- Subjects with constipation or suspected severe gastric motility disorder;
- Women with positive pregnancy tests or pregnancy plans, and women in lactation;
- Subjects who have participated in any other clinical trials within the last 3 months;
- Subjects with any other conditions that the investigator considered inappropriate for inclusion.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: OSS group
Bowel preparation for colonoscopy was performed using oral sulfate solution as laxative
|
OSS contained 17.5 g sodium sulfate, 3.13 g potassium sulfate, 1.6 g magnesium sulfate, and flavoring agents in an aqueous liquid form supplied in a 177 mL bottle.
Take 177ml sodium, potassium and magnesium sulfates oral solution (diluted to 480ml) within 30 minutes 14-16 hours before colonoscopy, followed by two doses of 480ml warm water within 1 hour; Repeat the procedure 3-4 hours before colonoscopy.
|
Active Comparator: Polyethylene glycol group
Bowel preparation for colonoscopy was performed using polyethylene glycol as laxative
|
Take 1000 ml polyethylene glycol electrolyte solution within 1 hour at 8 p.m. the day before colonoscopy; take 2000 ml polyethylene glycol electrolyte solution within 2 hour 4-6 hours before colonoscopy.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Bowel preparation adequate rate
Time Frame: 30 minutes
|
Proportion of subjects with total Boston bowel preparation scale (BBPS) score (total colon) ≥6.
|
30 minutes
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Boston bowel preparation scale (BBPS) score
Time Frame: 30 minutes
|
The BBPS scoring rules: 0, unprepared colon segment with mucosa not seen because of solid stool that cannot be cleared; 1, portion of mucosa of the colon segment seen, but other areas of the colon segment are not well seen because of staining, residual stool, and/or opaque liquid; 2, minor amount of residual staining, small fragments of stool, and/or opaque liquid, but mucosa of colon segment is seen well; 3, entire mucosa of colon segment seen well, with no residual staining, small fragments of stool, or opaque liquid. the higher the score, the better the quality of bowel preparation. 3 intestinal segments were scored separately: the right side of the colon (including the cecum and ascending colon), the transverse section of the colon (including the hepatic and splenic flexures), and the left side of the colon (including the descending colon, sigmoid colon, and rectum). Total BBPS score (0-9, the higher the score, the better the quality of bowel preparation). |
30 minutes
|
Acceptability of laxatives by questionnaire survey
Time Frame: 12 hours
|
The proportion of people who accept the laxative.
Level I: the laxative has good taste and is easy to take; the intestinal clearing fluid is drunk smoothly; the intestinal preparation process is easily tolerated; Level II: The laxative has a general taste and is easy to take.
The intestinal fluid is basically drunk on time, and the intestinal preparation process is barely tolerated; Level III: unacceptable laxative taste, difficult to take medicine, unable to drink the clear bowel fluid on time, intolerable bowel preparation process, refuse similar experience in the future.
Under level I and Level II, the laxative was considered to be acceptable.
Under level III, the laxative was considered not to be acceptable.
|
12 hours
|
Colonoscopy completion rate
Time Frame: 30 minutes
|
Proportion of subjects receiving complete colonoscopy
|
30 minutes
|
Incidence of laxative-related adverse events assessed by clinical examinations
Time Frame: 8 days
|
Physical examination (skin, mucous membranes, lymph nodes, head, neck, chest, abdomen, limbs), vital signs (temperature, respirations, heart rate, blood pressure), blood routine, urine routine, blood biochemistry (DBIL, TBIL, UREA, Cr, AST, ALT, TP, ALB, GLU, TG, TC, CK, ALP, K, Na, Cl, Ca, Mg, UA), coagulation function, and 12-lead electrocardiogram were performed within 7 days before taking laxatives.
The clinical examinations were repeated on the same day after the colonoscopy.
All abnormal changes in clinical examination results will be assessed by clinical specialists to determine if they are related to laxative intake.
Incidence was calculated as the number of subjects with laxative-related adverse events divided by the total number of subjects.
