Introduction. Colonoscopy is considered as a gold standard investigation for screening of colorectal cancer and other lower gastrointestinal pathologies. Adequate bowel preparation is absolutely necessary for a fruitful colonoscopy. Various bowel cleansing agents are being used for his purpose. The aim of the present study was to compare the two bowel cleansing agents: a single dose of Polyethylene Glycol (PEG) solution and a split dose of Sodium Picosulfate (Na PICOSUL) tablet with regards to cleansing efficacy and tolerability among the patients scheduled for colonoscopy. Methods. It is an open-label hospital-based observational study. A total of sixty-four patients were grouped randomly into two groups of bowel cleansing agents that are PEG and Na PICOSUL during the study period between 1st December 2015 and 30th November 2016. Patients’ tolerability was evaluated using a structured questionnaire, and the bowel cleansing efficacy was evaluated using the Aronchick Bowel Preparation Scale (ABPS). Results. The group that received PEG solution was found to have better efficacy than that which received Na PICOSUL tablet (63.3% versus 29.4%, respectively, with a P value < 0.028) with excellent grade as per ABPS. The Na PICOSUL group was found better in terms of tolerability than the PEG group as nausea/vomiting was encountered significantly higher in the PEG group than in the Na PICOSUL group (43.3% versus 11.8%, respectively, with a P value < 0.01). Conclusions. Colonic preparation with a split dose of Na PICOSUL tablet was better tolerated than the evening before regimen of PEG solution. However, PEG solution was found to be more efficacious in bowel cleansing, but procedural performance and lesion detection were similar for both agents.

Background & Aims: To compare the eficacy and tolerance of sodium picosulphate/magnesium citrate(PMC) and polyethylene glycol (PEG) in a single or split dose regimen for colonoscopy bowel preparation.Methods: A prospective, randomized, endoscopist-blinded, multicenter study. The patients were randomly assigned to receive PMC (PMC4/0) or PEG (PEG4/0) in a single dose 4L day before colonoscopy or a split dose 2+2L PMC (PMC2/2) or 3+1L PEG (PEG3/1) one day before and in the morning before the colonoscopy. Each patient was interviewed to determine his/her subjective tolerance of the preparation before the procedure. The quality of bowel cleansing was assessed in a blinded test performed by multiple endoscopists using the Aronchick scale.Results: A total of 600 patients were enrolled, 88.2% were included in the analysis. Satisfactory bowel cleansing (Aronchick score 1 and 2) was signicantly more frequent when a split dose was used irrespective of the solution type (81.6% PMC2/2, 87.3% PEG3/1 vs. 73.0% PEG4/0, p = 0.024). In single dose regimens, PMC performed better than PEG (82.6% vs. 73.0%). Single or split dose PMC preparations were comparable. A PMC based solution was generally better tolerated than PEG regardless of the regimen used (p < 0.001). Nausea was reported mostly after the 4L PEG (32.8%, p < 0.001), incontinence after a split PMC dose (34.4%, p = 0.002), and bloating after the 4L PEG (38.0%, p < 0.001). There was no significant difference in the prevalence of vomiting.Conclusion: Colonic preparation with PMC yields similar results as a split PEG dose, regardless of whether PMC is administered in single or separate doses. PMC is better tolerated than any PEG-based preparation. A single 4L PEG the day before the colonoscopy is less appropriate for bowel cleansing.

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.

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.

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 Preparation

Background. Currently, there is no generally accepted universal protocol for bowel preparation before colonoscopy in children. Aim. The aim of the study was to compare three different 1-day bowel preparation methods for a pediatric elective colonoscopy in terms of their efficacy, safety, and patient-reported tolerability. Material and Methods. The study was randomized, prospective, and investigator-blinded. All children aged 10 to 18 years consecutively referred to the tertiary pediatric gastroenterology unit were enrolled. The participants were randomized to receive polyethylene glycol 3350 combined with bisacodyl (PEG-bisacodyl group), or polyethylene glycol 4000 with electrolytes (PEG-ELS group), or sodium picosulphate plus magnesium oxide plus citric acid (NaPico+MgCit group). Bowel preparation was assessed according to the Boston Bowel Preparation Scale (BBPS). For patient tolerability and acceptability, questionnaires were obtained. Results. One hundred twenty-three children were allocated to three age- and sex-matched groups. All of the patients completed colonoscopies with visualization of the cecum. There was no difference among the groups for the mean BBPS score. A total of 73 patients (59.3%) experienced minor adverse events. No serious adverse events occurred in any group. Nausea was the only symptom more frequent in the PEG-ELS group compared to the NaPico+MgCit group (p=0.04), and apathy was the only symptom more frequent in PEG-bisacodyl than in the NaPico+MgCit group (p=0.04). All of the patients were able to complete 75% or more of the study protocol, and 85.4% were able to complete the full regimen. The acceptability was the highest in the NaPico+MgCit group with respect to the patient’s grade for palatability, low volume of the solution, and willingness to repeat the same protocol. Conclusion. All bowel cleansing methods show similar efficacy. However, because of the higher tolerability and acceptability profile, the NaPico+MgCit-based regimen appears to be the most proper for colonoscopy preparation in children.

Background: Adequate bowel preparation prior to colonoscopy is essential for visualization of the colonic mucosa to maximize adenoma and polyp detection. The risk of inadequate bowel cleansing is heightened if the patient is older, male, overweight, and has comorbidities, such as diabetes. This post hoc analysis of the combined MORA and NOCT clinical trials explores the efficacy of evening/morning split-dose regimens of NER1006 (PLENVU®, Norgine Ltd), a 1-liter polyethylene glycol (PEG) bowel preparation, to evaluate its bowel-cleansing efficacy in patients at risk for inadequate cleansing. Methods: Patients requiring colonoscopy were randomized to receive evening/morning split-dosing of either NER1006, 2-liter (2L) PEG and ascorbate, or oral sulfate solution (OSS). Bowel-cleansing efficacy was assessed by treatment-blinded central readers using the validated Harefield Cleansing Scale (HCS). Results: Split-dose NER1006 was associated with high levels of cleansing, ranging between 87.0% and 94.0% across all patient subtypes ( n = 551), including patients with obesity or diabetes. However, patients aged >65 years and <45 years showed significantly greater rates of successful cleansing than patients aged 45–65 years (94.0% versus 94.2% versus 87.0%, p = 0.002). The high-risk patient subgroup, which included obese males aged ⩾60 years, had significantly improved overall and high-quality bowel-cleansing success rates of 100% (33/33) and 72.7% (27/33) on the HCS with NER1006, compared with 86.7% (26/30) and 50% (15/30) with the comparator solutions ( p = 0.015 and p = 0.033, respectively). In this high-risk subgroup, adenoma detection was greater per patient receiving NER1006 versus the comparator group (1.82 versus 0.93, p = 0.041). NER1006 was the only treatment that enabled the detection of patients with ⩾5 adenomas [9.1% (3/33) versus 0/30, p = 0.047]. Conclusion: NER1006 effectively cleansed a broad range of patients and offered superior bowel cleansing versus 2LPEG/OSS in patients at increased risk of colorectal cancer. Future research should establish whether more effective cleansing also enables improved adenoma detection. Plain language summary A low-volume bowel preparation solution to better detect lesions associated with colorectal cancer during colonoscopy Colorectal cancer (CRC) is the fourth most commonly diagnosed cancer in the world. Obese men over the age of 65 years are at particularly increased risk of developing CRC. If the changes in their large intestine (colon) could be seen more clearly during a colonoscopy (where a small camera is inserted via the anus to examine the bowels from the inside), patients who need treatment would be diagnosed earlier, thus improving their chances of survival. In this paper we discuss the use of a bowel preparation solution that is more convenient for patients (less to drink) but also cleans bowels more effectively, meaning more lesions are detected than when other solutions are used. This improved cleansing, and thus better visualization, occurred in a range of patients, including those at higher risk of CRC, such as older, overweight men.
