ABSTRACT
Objective@#To investigate the situation and influencing factors of bowel cleansing in patients before colonoscopy, and to provide reference for guiding patients′ bowel preparation.@*Methods@#The clinical data of 421 patients undergoing electronic colonoscopy in the endoscopy center of the second people′s hospital of Lu′an city in Anhui Province from April to September 2018, Prospective collection by systematic sampling, including general data of patients, clinical data of bowel preparation and score of Boston bowel preparation scale. Univariate analysis and logistic regression analysis were performed on the relevant factors of bowel preparation.@*Results@#Among the 421 patients, 52 cases were not eligible for intestinal cleaning, and the unqualified rate was 12.35%(52/421). Logistic regression analysis showed that: Total amount of drinking water prepared for intestinal tract before colonoscopy (OR=1.674, P=0.018),The total times of defecations after taking the drug (OR=1.270, P=0.014), the characteristics of last stool before colonoscopy (OR=2.211, P=0.042), the diet the day before colonoscopy (OR=0.553, P=0.006) , body mass index (OR=1.111, P=0.042), and intestinal diseases (P=0.022), were all intestinal clearance independent influencing factors of cleaning effect; While took laxative type (mannitol/PEG), drunk water speed (within 3 hours), first defecation time, the site of drinking bowel-clearing drugs, daily activity, none of the above factors affected the bowel preparation effect (P>0.05) .@*Conclusion@#Before colonoscopy, there were many factors affecting the cleaning effect of the intestine. The total water intake of intestinal preparation was less than 2 000 ml, the total number of defecation after taking medicine was less than 5 times, the last defecation contained residue, the day before the examination was strictly fasting, the body mass index was less than 18.5 kg/m2, and colitis, enterelcosis and occupying lesion are independent risk factors for intestinal cleaning. Attention should be paid to the comfort care and guidance of intestinal preparation, and prospective intervention can effectively improve the cleaning effect of intestinal tract.
ABSTRACT
Objective To evaluate the influence of the preparation-to-colonoscopy interval, diet control and excise on bowel preparation quality in the split-dose method for colonoscopy. Methods Observational study, prospective cohort study design, three bowel preparation methods were set up in different departments for A, B, C 3 groups, each group of 110 cases. In group A, no movement was required. Diet preparation was 3 days earlier than the examination, and take all the medicine in once at 20:00 the day before examination, group B, 1 L medicine required for 20 minutes movement, diet preparation was 1 day earlier than the examination, and take the medicine in twice the day before examination at 14:00, group C, keep walking during taking the medicine, diet preparation was 1 day earlier than the examination, and took all the medicine in once the day before examination at 20:00. The Boston Bowel Preparation Scale was used to evaluate the bowel cleansing quality. A questionnaire was administered to investigate patients′tolerability and safety. Results A total of 330 consecutive patients undergoing colonoscopy. There was no significance among three groups on bowel cleansing quality(P>0.05). However, the number ofexcellently cleanedwas higher in group B than the others, in group A,B and C respectively 30, 46, 29 cases, the difference was significant (χ2=7.627, P=0.022). Group B was superior to the others in terms of comfort, sleep quality, hunger, and discomfort, the difference was significant (χ2=19.425, 6.687 and 8.130, P < 0.01 or 0.05). Group B was also superior to the others in terms of the compliance of completing the preparation under the doctors′advice (χ2=14.756, P=0.001) and exercises (χ2=11.848, P=0.001). Conclusions The new method shortened the time of the diet control and set the exercises time to 20 minutes. So it was found to have a higher level of safety, bowel preparation quality and tolerability.
ABSTRACT
BACKGROUND AND AIMS: The goal of this study was to examine whether certain variables are associated with insertion time during colonoscopy. METHODS: A total of 703 consecutive subjects underwent colonoscopy by a single endoscopist from April of 1998 to August of 1998. The insertion time during colonoscopy was checked and the factors that may affect insertion time were analyzed. RESULTS: The indications for colonoscopy were bowel habit change (34.8%), the diagnosis of and follow up for colonic neoplastic disease (31.6%), abdominal pain (22.8%), thin stool caliber (19.2%), hematochezia (16.1%), routine examination (10.7%), inflammatory bowel disease (9.4%), tenesmus (8.8%) and a family history of colonic disease (3.1%). Of 703 subjects, complete colonoscopy was possible in 678 (96.4%). Reasons for incomplete insertion included inadequate bowel cleaning (n=11), pain (n=6), a history of operations (n=3), and others (n=5). Therefore, the adjusted completion rate was 97.9% (678/692). The mean insertion time in complete colonoscopy was 7.07 4.26 min (range; 2~35 min). Multivariable analysis revealed that inadequacy of bowel preparation was significantly associated with prolonged (>10 min) insertion time (p=0.005), whereas the history of colorectal resection was inversely associated with prolonged insertion time (p=0.010). CONCLUSIONS: Among the factors affecting insertion time during colonoscopy, cleanness of the bowels is the only correctable factor.
