Background: Colonoscopy is an effective surveillance for the diagnosis and screening of colorectal cancer (CRC). Prior to the procedure, people would take laxatives for a good visualization of bowel texture. Although a split-dose bowel preparation has become popular, many anesthesiologists are concerned about pulmonary aspiration. Objective: To study the gastric residual volume and pH in patients taking split-dose bowel preparation as compared to those having laxatives on the day before the procedure. Materials and Methods: One hundred patients were randomized equally into two groups, as A for a single-dose, and B for a split-dose regimen. All patients underwent endoscopy under standard anesthetic care. The total gastric residual volume was suctioned, and pH was measured through the endoscope. The surgical team was unaware of the study protocol. The quality of bowel cleansing was assessed by the endoscopist using the Boston Bowel Preparation Scale (BBPS). Results: The bowel cleansing, the latency period, the endoscopist and patients’ satisfaction of single-and split-dose group were 7.06±1.4 and 8.14±1.1, 13.3±1.1 and 4.2±0.4 hours, 62.0% and 94.0%, and 90.0% and 74.0%, respectively. They all showed statistically significant differences between the two groups (p<0.05). Conclusion: The gastric residual volume and pH were not different between the split and single-dose preparations. Therefore, it might not increase the risk of aspiration pneumonitis. However, the split-dose technique was more effective in colon cleansing, patients’ tolerability, acceptability, and compliance than the preparations administered entirely the day or evening before the surgical procedure.

The aim of this study was to compare gastric residual volume (GRV) in patients given a split-dose versus a conventional single-dose of polyethylene glycol (PEG) preparation before undergoing anesthetic colonoscopy. Methods. In a prospective observational study, we assessed GRV in outpatients undergoing same-day anesthetic gastroscopy and colonoscopy between October 8 and December 30 of 2016. Outpatients were assigned to the split-dose (1 L PEG in the prior evening and 1 L PEG 2–4 h before endoscopy) or single-dose (ingestion of 2 L PEG ≥ 6 h before endoscopy) regimen randomly. Bowel cleansing quality was assessed with the Boston Bowel Preparation Scale (BBPS). Results. The median GRV in the split-dose group (17 ml, with a range of 0–50 ml; N=65) was significantly lower than that in the single-dose group (22 ml, with a range of 0–62 ml; N=64; p=0.005), with a better bowel cleansing quality (BBPS score 8.05±0.82 versus 7.64±1.21; p=0.028). GRV was not associated with diabetes or the use of medications. Conclusions. GRV after a split-dose preparation and fasting for 2–4 hours is not larger than that after a conventional single-dose preparation and fasting for 6–8 hours. The data indicates that the split-dose bowel preparation might not increase the risk of aspiration.

597 Background: Though numerous researches enabled decrease of the bowel preparation solution volume, it is still a major complaint of patients preparing colonoscopy. There have been studied that additional administration of laxatives could lessen the amount of aqueous formula with prokinetic effect. Prucalopride is a serotonin (5-HT4) receptor agonist which stimulate colonic mass movements and provide main propulsive force for defecation. The aim of this study is to compare 2-L PEG-Asc and 1-L PEG-Asc plus prucalopride for quality of bowel cleansing while preparing for colonoscopy and patient compliance. Methods: Two hundred patients were prospectively enrolled. Patients referred for colonoscopy were divided into group A (the split-dose 2-L PEG-Asc) and group B (1-L PEG-Asc + prucalopride) randomly. During colonoscopy, each patient’s bowel preparation quality was evaluated with The Boston Bowel Preparation Scale (BBPS) and Aronchick Preparation Scale (APS). The tolerability and satisfaction of patients was determined based on a questionnaire-based survey. Results: One hundred patients received either 2-L PEG-Asc or 1-L PEG-Asc with prucalopride. Regarding colon cleansing outcome (BPPS and APS), the 1-L PEG-Asc with prucalopride group showed similar, but non-inferior results compared to the 2-L PEG-Asc group on both BBPS (7.65±1.27 vs 7.52±1.40, p = 0.586) and APS scales (93.3% vs 95%, p = 0.717). Tolerability was similar for both 1-L PEG-Asc with prucalopride and 2-L PEG-Asc. Conclusions: 1-L PEG-Asc plus prucalopride preparation showed comparable result to traditional 2-L PEG-Asc preparation. 1-L PEG-Asc plus prucalopride preparation method could be an alternative method for bowel preparation which can relieve patient’s discomfort.

Background. The efficacy of colonoscopy in detecting abnormalities within the colon is highly dependent on the adequacy of the bowel preparation. The objective of this study was to compare the efficacy, safety, and tolerability of PEG lavage and split-dose PEG lavage with specific emphasis on the cleanliness of the right colon.Methods. The study was a prospective, randomized, two-arm, controlled trial of 237 patients. Patients between the age of 50 and 75 years were referred to an outpatient university screening clinic for colonoscopy. Patients were allocated to receive either a single 4 L PEG lavage or a split-dose PEG lavage.Results. Overall, the bowel preparation was superior in the split-dose group compared with the single-dose group (mean Ottawa score 3.50 ± 2.89 versus 5.96 ± 3.53;P<0.05) and resulted in less overall fluid in the colon. This effect was observed across all segments of the colon assessed.Conclusions. The current study supports use of a split-dose PEG lavage over a single large volume lavage for superior bowel cleanliness, which may improve polyp detection. This trial is registered with ClinicalTrials.gov identifierNCT01610856.

BACKGROUND: Despite the wealth of research investigating bowel cleansing efficacy, there are very little data on the timing or frequency of bowel movements after each agent is ingested.OBJECTIVE: To examine the effect of each component of a three-day combined sodium picosulphate/magnesium citrate (PSLX) and bisacodyl regimen on the timing and frequency of bowel activity in patients undergoing colonoscopy.METHODS: Outpatients booked for colonoscopy were asked to complete a diary of their bowel preparation that tracked the timing of bowel movements. Bowel preparation quality was assessed using the Ottawa Bowel Preparation Scale. Bowel activity was compared with baseline and correlated with colon cleansing. Subgroup analysis was performed examining the effect of timing of the procedure and split-dose regimens.RESULTS: One hundred patients undergoing colon cleansing received bisacodyl 10 mg at 17:00 three days and two days before the day of colonoscopy. In one group, both sachets of PSLX were given the night before colonoscopy, while the second group, whose colonoscopies were scheduled after 11:00, ingested one sachet the night before and the second sachet at 06:00 on the day of colonoscopy. Patients had a mean of 1.7 bowel movements per day in the seven days before starting the cleansing regimen. Both doses of bisacodyl tablets resulted in a significant increase in the mean number of bowel movements compared with baseline (3.3/day first dose; 3.8/day second dose [P=0.03 and 0.001, respectively]). Each dose of PSLX also resulted in a significant increase in bowel movement frequency compared with baseline, with means of 4.4, 6.3 and 4.5 bowel movements after each dose. The mean time to the final bowel movement following the second sachet of PSLX was 8.9 h when taken the night before, and 3.9 h when taken the morning of the procedure. Bowel preparation quality significantly correlated with bowel frequency when total bowel movements were considered and when only the effects of bisacodyl were accounted for (P<0.01 for each).DISCUSSION: These data demonstrate that the addition of bisacodyl before PSLX ingestion has a significant additive effect on bowel frequency and correlates with bowel cleansing quality. The timing of the resulting bowel movements have practical implications for sleep and travel times to endoscopy suites.

Colonoscopy Quality

Introduction: The aim of the study was to compare the efficacy and tolerability of polyethylene glycol/ascorbic acid (PEGA), sodium picosulfate/ magnesium citrate (SPMC) and the oral sulfate formula (SIR) in a single- or split-dose regimen for bowel preparation prior to colonoscopy. Methods: Randomised, multicentre, open-label study. The subjects received either PEGA, SPMC or SIR in the single- or split-dose regimen before the colonoscopy. Quality and tolerability of the preparation and complaints during preparation were recorded using a 5 point scale. Results: 558 subject were analysed. Preparation quality was comparable in the single-dose regimen. The rate of satisfactory bowel cleansing (Aronchick score 1+2) was higher for split-dose SIR and PEGA compared to SPMC (95.6%, 86.2% vs. 72.5%, p<0.028). The highest tolerance rate (score 1+2) was reported for SPMC (82.3%, p<0.003) and the lowest for single-dose SIR (34.8%, p=0.008). The lowest frequency of nausea (10.4%) was observed for SPMC. The highest prevalence of bloating was linked with the use of PEGA (34.0%). Conclusion: Differences in bowel preparation quality were apparent only in the split-dose regimen, with SIR rated as most efficient. SPMC was the best tolerated formula. The split-dose regimen is more effective than single-dose preparation used in the evening before the examination.
