Background: The incidence of inadequate bowel preparation before elective colonoscopy in this region has never been studied. Materials and Methods: The authors prospectively described the incidence and factors related to inadequate bowel preparation in Thammasat university hospital. Bowel preparation quality was accessed by using Aronchick scale. Factors associated with inadequate bowel preparation were also recorded. Results: Two hundred patients undergoing elective outpatient colonoscopy were enrolled. Inadequate and fair bowel preparation was documented in 9 and 43%, respectively. Factors associated with inadequate bowel preparation were incomplete cleansing agent ingestion (odds ratio 7.7; 95%CI 1.62-36.64) and patient's unrecognization of vegetable avoidance (odds ratio 3.26; 95%CI 1.14-9.28). Conclusions: Compared with previous reported, inadequate bowel preparation was seen less in our study, however, more patients with fair bowel preparation was documented. Further study aiming at investigating the type and amount of fiber contained in diet before elective colonoscopy should be commenced.

Purpose: The purpose of this study was to evaluate the effects of an educational video program on bowel preparation for a colonoscopy. Methods: The study used a non-equivalent control group and non-synchronized design as a quasi-experimental research involving 101 participants undergoing bowel preparation for a colonoscopy (experimental group 51, control group 50 subjects) at W. university hospital, from Aug. 7 to Oct. 31, 2013. The control group received verbal education with an explanatory note while the experimental group received education using a video program. To measure knowledge of diet restrictions and compliance with ingesting bowel preparation solutions, a questionnaire, based on The Korean Society of Gastrointestinal Endoscopy's Guide (2003), developed by Sam-Sook You, was used after revisions and supplementation was done. To measure bowel cleanness, the 'Aronchick Bowel Preparation Scale' was adopted. Data were analyzed using the SPSS WIN 12.0 program. Results: A higher proportion of the experimental group showed a positive change in knowledge level on diet restrictions (U=1011.50, p =.035) and ingestion of bowel preparation solutions (U=980.50, p =.019), a higher level of compliance with diet restrictions (U=638.50, p <.001), ingesting bowel preparation solutions (U=668.00, p <.001) and the level of bowel cleanness (${\chi}^2$=17.00, p <.001) than the control group. Conclusion: The results of this study indicate that a video educational program for patients having a colonoscopy can improve knowledge, level of compliance with diet restrictions, ingestion of bowel preparation solutions, and bowel cleanness. Therefore video educational program should be used with this patient group.

Purpose: The purpose of this study was to develop video assisted education on bowel preparation for colonoscopy (VEBPC) and use a snartphone to evaluate effects of the VEBPC. Methods: Adult patients who were scheduled for colonoscopy were recruited from a university general hospital and randomly assigned to three groups. Group 1 (n=30) watched the video using a computer set in the endoscope consulting room. Group 2 (n=29) watched it using a smartphone, and group 3, the control group (n=29) received education with existing instructions at the reservation-reception desk. Participants were evaluated on knowledge on taking bowel preparation agents and diet, compliance on taking bowel preparation agents and diet, satisfaction with education, and actual level of bowel preparation. Results: Group 1 and 2 showed significantly (p<.001) higher scores for knowledge, compliance, and satisfaction compared to the control group. However, in post-hoc test analyses there were no significant differences in these variables between group 1 and 2. No significant difference was found in the actual level of bowel preparation among the three groups. Conclusion: Findings from this study show that VEBPC using smartphone is a better option than existing educational methods. However, replication studies are necessary to confirm these findings.

The purpose of this study was to identify the effects of bowel preparation convergence program for colonoscopy. This study used a nonequivalent control group pretest-posttest design. A sample of 75 clients, who were scheduled for colonoscopy, was included. The experimental group was given bowel preparation convergence program including audiovisual education, walking-exercise and telephone counseling. The data were collected using a structured questionnaire and colonoscopy monitoring and were analyzed using SPSS 21.0 program. The experimental group reported significantly higher compliance of taking bowel preparation agents and test satisfaction(p=.002; p=.001), lower test difficulty and test discomfort than those of the control group(p=.002; p=.001). There were significant differences in level of bowel cleansing and test time required except compliance of diet restriction between groups(p<.001; p=.001; p=.108). This findings indicate that bowel preparation convergence program can be an effective nursing intervention for colonoscopy. The convergence intervention for diagnostic test is needed to be developed in clinical practice.

Background: Because of its efficacy and safety, polyethylene glycol (PEG) is generally used to prepare for colonoscopy. However, the side effects of PEG, including nausea, vomiting, abdominal discomfort, pain, and general weakness, tend to decrease patient compliance and satisfaction. The aim of this study is to investigate the efficacy and safety of PEG with 0.1 mg ramosetron on colonoscopy patients who had difficulty taking PEG due to side effects or large volume. Methods: From January to August in 2012, 28 patients who visited Yeungnam University hospital for a colonoscopy were prospectively enrolled. All enrolled patients were previous history underwent colonoscopy using PEG only in our hospital. The efficacy and safety of ramosetron were assessed through the use of a questionnaire, and compared previous bowel preparation. Results: Compared to previous examination, the patients using the ramosetron reported less nausea, vomiting, abdominal discomfort, and abdominal pain, as well as a higher degree of compliance and satisfaction of the patient. There were no side effects reported with the use of ramosetron. However, overall bowel preparation quality was not better than the previous examination. Conclusion: In case of the use of ramosetron in combination with PEG for bowel preparation, patients experienced a higher rate of compliance and tolerance. Looking forward, ramosetron may become an option of pretreatment for bowel preparation.

Purpose: This study was a randomized single-blind trial of whole versus split-dose PEG solutions for colonoscopy preparation to compare the patient compliance, quality of bowel cleansing, and endoscopist's satisfaction. Methods: The participants were recruited from outpatients who planned to receive colonoscopy of C hospital in Busan. Sixty participants were randomly assigned to receive either a spit-dose group(n=30) consuming $2{\ell}$ of PEG solution twice, or a whole-dose group(n=30), consuming $4{\ell}$ of PEG solution once. These participants completed the questionnaire to assess their compliance before colonoscopy. The quality of bowel cleansing was assessed using the Ottawa Scale with the endoscopist who was blinded to the type of preparation, and their satisfaction by using VAS. Results: The participants who did not completely consume $4{\ell}$ of PEG solution were less in split-dose than in whole-dose group (0% vs 13.3%). The split-dose group complained less about abdominal pain(t=2.644, p=0.009) and abdominal bloating(t=2.802, p=0.013) with a statistical significance. For the quality of bowel preparation, there were no significant differences in the bowel cleansing scores and the endoscopist's satisfaction between two groups. Conclusion: Colonic preparation with split-dose of PEG solution could be a more useful method for better patient compliance, with no significant impact on bowel cleansing quality.

The widely used polyethylene glycol (PEG)-based solutions have been proven effective for bowel preparation when 4 L of the solution is administered before colonoscopy. However, large volumes of the solutions are generally poorly tolerated. A new PEG-based solution consisting of 2 L of PEG and a high dose of ascorbic acid has recently become available. Electrolyte abnormalities caused by PEG-based solutions have rarely been reported. We report on a case of acute severe hyponatremia with associated generalized tonic-clonic seizures after bowel preparation with a low-volume PEG plus ascorbic acid solution in a 74-year-old woman with no history of seizures. She took a beta blocker, an angiotensin-converting enzyme inhibitor, and glimepiride for hypertension and diabetes mellitus. She showed general weakness, nausea, agitation, muscle cramping, and seizures after ingestion of the PEG plus ascorbic acid solution. Her serum sodium level was 112 mEq/L. Her symptoms improved after intravenous administration of hypertonic saline. Physicians should pay attention to screening for electrolytes and development of neurological symptoms during bowel preparation.

The purpose of this study was determine the effect of sugar addition or gum chewing on the nausea, disgust, bowel preparation scale of through the subject taking the Coolprep as bowel preparation for colonoscopy. A randomized controledl trial design was used. There were 120 participants in the study, aged 20-65. The data were analyzed using one-way ANOVA and X² test using SPSS/WIN 25.0. There was no significant difference in nausea, disgust and bowel preparation scale among sugar additions, chewing gum and standard method groups. This study result therefore, convergent efforts are needed to reduce the difficulty of taking. The subjects who participated in the experiment did not have any special side effects such as hyperglycemia, so it is considered to be partially applicable to individual preferences.

Purpose: To compare the effectiveness, tolerability, acceptability, and safety of sodium picosulphate with magnesium citrate (PS/Mg) and polyethylene glycol (PEG) in children (≤18 years) preparing for colonoscopy. Methods: Three electronic databases (MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials) were searched till July 2020. Only randomized controlled trials (RCTs) were included. At least two authors independently selected studies and performed risk of bias assessment and data extraction. Results: Four RCTs (n=390), with overall good quality were included. A meta-analysis of two trials (n=224) found no statistically significant difference between the groups with respect to the proportion of patients who had excellent and good scores (≥6 points) according to the Boston Bowel Preparation Scale (relative risk: 0.99; 95% confidence interval [CI]: 0.90 to 1.08). Excellent and good scores were observed in both groups in approximately 90% of children. A meta-analysis of two other trials (n=150) showed no significant difference between the groups with respect to the mean total score for the Ottawa Bowel Preparation Scale (mean difference: 0.20; 95% CI: -0.74 to 1.14). Both regimens provided a comparable safety profile; however, PS/Mg was significantly superior to high volume PEG in terms of tolerability (abdominal pain, nausea, vomiting, bloating/flatulence/fullness) and acceptability (ease of formulation consumption, taste acceptance, need for nasogastric tube, compliance with full dose). Conclusion: PS/Mg provides a quality and safety profile similar to PEG for bowel cleansing; however, it has better acceptance and tolerance in children preparing for colonoscopy.
