Polyethylene glycol 3350 without electrolytes: a new safe, effective, and palatable bowel preparation for colonoscopy in children

OBJECTIVE: To assess safety, efficacy, and acceptance of polyethylene glycol 3350 without electrolytes (PEG) for bowel preparation for colonoscopy in children.Study design In a prospective study, 46 children (mean age, 11.2 years; range, 2.8-17.8) were given PEG at a dose of 1.5 g/kg/day for 4 days before colonoscopy. Patients were allowed to mix PEG in the beverage of their choice. Stool frequency and adverse effects were monitored during PEG therapy. Compliance, tolerance, and quality of colonic preparation were assessed. Serum electrolytes were measured before and after PEG therapy in 29 children. RESULTS: Daily stool frequency increased with PEG therapy from baseline of 2.6+/-0.3 to 3.0+/-0.5 on day 1, 4.6+/-0.4 on day 2, 5.5+/-0.7 on day 3, and 6.0+/-0.6 on day 4 (days 2, 3, and 4, P<.001 for difference vs baseline). The colonic preparations were rated as excellent or good in 91% and 95% in the right and left colon, respectively, at endoscopy. Adverse effects were mild nausea (13%), abdominal pain (11 %), and vomiting (11%). Electrolyte profile revealed small, clinically insignificant changes with PEG therapy. Compliance and tolerance were rated as excellent by 89% and 85% of patients, respectively. CONCLUSIONS: Electrolyte-free PEG 3350 can be used as an effective and safe bowel preparation that is well accepted by children for colonoscopy.     

A prospective study comparing oral sodium phosphate solution to a bowel cleansing preparation with nutrition food package in children

OBJECTIVE: The inability of children to comply with bowel preparation regimens can result in inadequate visualization of the colon. This study compares the safety, efficacy, and patient acceptance of a prepackaged diet kit plus a magnesium citrate/bisacodyl bowel cleansing regimen with a clear liquid diet and sodium phosphate solution regimen in children undergoing colonoscopy. METHODS: Children scheduled for a diagnostic colonoscopy, were randomly assigned to receive a prepackaged diet kit and a magnesium citrate/bisacodyl laxative (group 1), or clear liquids and sodium phosphate solution (group 2). The patients and their parents completed a questionnaire to evaluate acceptance of their assigned regimen before colonoscopy. The endoscopists, blinded to the type of bowel preparation, rated bowel cleansing. RESULTS: Sixty two children (28 males, 34 females) with mean age 12.5 years participated. Thirty six and 26 patients were in groups 1 and 2 respectively. Overall cleansing was rated significantly superior in group 1 compared to group 2 as was amount of retained feces (P = .013 for both). The overall frequency of reported side-effects was lower in group 1 than (83.3%, 30/36) than in group 2 (100.0%, 26/26) (P = 0.03). The preparations were otherwise equivalent in regards to compliance and patient tolerance. CONCLUSIONS: Although both regimens were comparable in adequacy of colon visualization, preparation tolerance, side effects and compliance profile in this pilot study, the prepackaged diet kit with magnesium citrate/bisacodyl laxative resulted in superior colon cleansing.

Randomised trial of two pharmacological methods of bowel preparation for day case colonoscopy.

AIMS: To undertake a prospective, single blind, randomised trial comparing the efficacy and tolerance of two outpatient colonoscopy bowel preparation regimens. METHODS: Patients aged between 18 months and 16 years being admitted for day case colonoscopy were allocated randomly to receive either Picolax (an oral, sugar free powder containing sodium picosulphate 10 mg/sachet with magnesium citrate) and clear fluids or bisacodyl tablets with an unrestricted diet and a phosphate enema just before colonoscopy. Patient compliance, bowel frequency, and associated symptoms were recorded, and the adequacy of the bowel preparation was assessed in a blinded manner. RESULTS: 63 of 66 patients completed the trial. Mean age, mean weight, extent of colonoscopy, and distribution of underlying pathology were similar in both groups. Bowel preparation was good or excellent in all of the patients in the Picolax group (n = 32) compared with 22 patients in the bisacodyl/phosphate enema group (n = 31). The latter group experienced more abdominal discomfort during bowel preparation but three of the Picolax group vomited and the lack of solid food distressed some children. CONCLUSIONS: All bowel preparation methods have limitations and unpleasant side effects but the use of Picolax and clear fluids proved superior to bisacodyl tablets and a phosphate enema in children undergoing day case colonoscopy.

Colorectal screening with single scan CT colonography in children

The purpose of this study was to evaluate the feasibility of single scan CT colonography (CTC) using polyethylene glycol electrolyte solution with contrast medium (PEG-C) bowel preparation in children. Seven patients suspected of colorectal elevated lesions were subjected to CTC. All patients underwent bowel preparation using polyethylene glycol electrolyte solution (PEG) at a dose of 32 ± 3 ml/kgBW before the day of CTC. The water-soluble contrast agent was given to the patients at a dose of 0.6 ± 0.1 ml/kgBW the next morning. After colonic air insufflation, the patient was scanned axially with a single run. After evaluation of multiplanar reformation images, 3-dimensional images (CT enema and virtual endoscopy image) were reconstructed. CT enema image was composed from air image and contrast-medium image. All studies were performed without complications. CTC showed the entire colon without blind spots in all patients with only single scan. In conclusion, the single scan CTC using PEG-C preparation is safe and less invasive compared to conventional CTC due to the shorter examination time and lower radiation dose.     

Polyethylene glycol without electrolytes for children with constipation and encopresis

BACKGROUND: Children with functional constipation and encopresis benefit from behavior modification and from long-term laxative medication. Polyethylene glycol without electrolytes has become the first option for many pediatric gastroenterologists. METHODS: Twenty-eight children treated with polyethylene glycol without electrolytes were compared with 21 children treated with milk of magnesia to evaluate the efficiency, acceptability, side effects, and treatment dosage of polyethylene glycol in long-term treatment of functional constipation and encopresis. Children were rated as "doing well," "improved," or "not doing well," depending on resolution of constipation and encopresis. RESULTS: At the 1-, 3-, 6-, and 12-month follow-ups, bowel movement frequency increased and soiling frequency decreased significantly in both groups. At the 1-month follow-up, children on polyethylene glycol were soiling more frequently (P < 0.01) and fewer were improved (P < 0.01). At the 3- and 6-month follow-ups, both groups had similarly improved. At the 12-month visit, 61% of children on polyethylene glycol and 67% of children on milk of magnesia were doing well. Children on polyethylene glycol soiled more frequently (P < 0.01). None refused polyethylene glycol, but 33% refused to take milk of magnesia. The mean initial treatment dosage of polyethylene glycol was 0.6 +/- 0.2 g/kg daily. Polyethylene glycol had no taste, and no loss of efficacy occurred. Polyethylene glycol did not cause clinically significant side effects. CONCLUSIONS: Polyethylene glycol without electrolytes is an alternative for long-term management of children with constipation and encopresis.     

Preparing the bowel for colonoscopy.

Bowel preparation methods for total colonoscopy in children generally involve whole gut irrigation with electrolyte lavage solutions, which in most children will require hospitalisation for nasogastric tube administration. The aim of the study was to determine the efficacy of oral bisacodyl combined with a single phosphate enema as a bowel preparation regimen in children. In an open prospective trial, 30 children (aged 18 months-15 years) were given oral bisacodyl on each morning of the two days before colonoscopy. The children were maintained on a normal diet. A phosphate enema was administered on the morning of the procedure. The adequacy of bowel preparation was graded as grade I if no faecal material was encountered, grade II if small amounts of faecal material were present in scattered locations, and grade III if there was poor preparation with faecal material precluding satisfactory visualisation of the bowel mucosa. Eight children (26.6%) had minor abdominal cramps when taking bisacodyl, but all had a previous history of similar pain. Five children (16.6%), all under 5 years of age, cried during the administration of phosphate enema. Bowel preparation was considered excellent (grade I) in 26 (86.6%) and good (grade II) in four (13.3%). In all patients adequate visualisation of the bowel mucosa was obtained. Oral bisacodyl combined with a single phosphate enema provides an ideal method of preparing the bowel for total colonoscopy. This preparation allows colonoscopy to be carried out as a day case procedure in children while maintaining them on a normal diet.     

Polyethylene glycol-electrolyte solution for intestinal clearance in children with refractory encopresis. A safe and effective therapeutic program

Severely constipated children with encopresis in whom outpatient management has failed frequently require several days of hospitalization, as well as conventional treatments involving cathartics and enemas. A balanced electrolyte solution of the nonabsorbable polymer polyethylene glycol (GoLytely, Braintree [Mass] Laboratories Inc) offers a safe and efficient method for clearing the intestine. Twenty-four patients with a mean age of 8.1 years (range, 0.8 to 17.6 years) and an average weight of 31.5 kg received polyethylene glycol-electrolyte solution: eight patients with encopresis were given it as treatment for severe fecal retention unresponsive to outpatient management; the other 16 were being prepared for colonoscopy. Weight, complete blood cell count, and serum electrolyte, serum urea nitrogen, and serum creatinine levels were measured before solution administration and two hours afterward. Abdominal roentgenograms were obtained from the encopretic patients. The two groups were comparable in age and weight. Polyethylene glycol-electrolyte solution was given at a rate of 14 to 40 mL/kg/h until clear fluid was excreted through the rectum. Intestines were cleaned out successfully in all patients, and side effects were minimal. Children with encopresis required an average of 11.8 L (574 mL/kg) given over 22.5 hours, while the other children needed only 4.0 L (128 mL/kg) given over 7.5 hours. Weight and serum electrolyte and creatinine levels did not change significantly in any patient. The hematocrit decreased only in encopretic patients (0.38 to 0.36 [37.6% to 35.8%]) and the serum urea nitrogen level decreased in the patients undergoing colonoscopy (3.6 to 2.0 mmol/L [10 to 8 mg/dL]).
