The role of a probiotics mixture in the treatment of childhood constipation: a pilot study

<p>Abstract</p> <p>Background</p> <p>Inconsistent data exist about the efficacy of probiotics in the treatment of constipation. Several studies in adults with constipation showed positive effects of probiotics on constipation. Inconsistent data exist regarding the effect of a single probiotic strain in constipated children. The aim of this pilot study was to determine the effect of a mixture of probiotics containing bifidobacteria and lactobacilli in the treatment of childhood constipation.</p> <p>Methods</p> <p>Children aged 4–16 years with constipation as defined by the Rome III criteria were eligible for the study. During a 4 week period, children received a daily mix of 4 × 10⁹colony forming units of a probiotic mixture (<it>Ecologic</it>^®<it>Relief</it>) containing Bifidobacteria (B.) bifidum, B. infantis, B. longum, Lactobacilli (L.) casei, L. plantarum and L. rhamnosus. Primary outcome measures were frequency of bowel movements (BMs) per week and stool consistency. Secondary outcome measures were number of faecal incontinence episodes per week, abdominal pain and side effects.</p> <p>Results</p> <p>Twenty children, 50% male, median age 8 (range 4–16) were included.</p> <p>The frequency of BMs per week increased from 2.0 (1.0–5.0) to 4.2 (0.0–16.0) in week 2 (p = 0.10) and 3.8 (2.1–7.0) in week 4 (p = 0.13). In 12 children presenting with <3 BMs/week, BMs per week increased significantly from 1.0 (0.0–2.0) to 3.0 (0.0–7.0) in week 2 (p = 0.01) and 3.0 (0.0–10.0) in week 4 (p = 0.01). The stool consistency was reported as hard in 7 children at baseline, in 4 children at week 2 (p = 0.23) and in 6 children after 4 weeks of treatment (p = 1.00). A significant decrease in number of faecal incontinence episodes per week was found in the entire group: 4.0 (0.0–35.0) to 1.5 (0.0–14.0) in week 2 (p = 0.01) and 0.3 (0.0–7.0) in week 4 (p = 0.001). The presence of abdominal pain decreased significantly from 45% to 25% in week 2 (p = 0.04) and 20% at week 4 (p = 0.006). No side effects were reported.</p> <p>Conclusion</p> <p>This pilot study shows that a mixture of probiotics, has positive effects on symptoms of constipation. To confirm these findings, a large randomised placebo controlled trial is required.</p

Magnetic resonance imaging of the lumbosacral spine in children with chronic constipation or non-retentive fecal incontinence: a prospective study

OBJECTIVE: To determine the prevalence of lumbosacral spine (LSS) abnormalities in children with defecation disorders, intractable constipation, or non-retentive fecal incontinence (NRFI) and evaluate whether LSS abnormalities on magnetic resonance imaging (MRI) are clinically detected by neurologic examination. STUDY DESIGN: MRI of the LSS and complete neurologic examination by a pediatric neurologist blinded to the MRI results were performed in patients with intractable defecation disorders. RESULTS: Patients with intractable constipation (n = 130; 76 males; median age, 11 years; range, 6-18 years), and patients with NRFI (n = 28; 18 males; median age, 10 years; range, 7-15 years) participated. One occult spina bifida (OSB) and 3 terminal filum lipomas were found in patients with a normal neurologic examination. One patient had a terminal filum lipoma and neurologic complaints. Gluteal cleft deviation was found in 3 of 4 patients with LSS abnormalities. Neurosurgical treatment was not required in any patient during the 12-week follow-up. CONCLUSIONS: MRI showed LSS abnormalities in 3% of patients with defecation disorders and normal neurologic examination, all of whom reported symptom relief at the 12-week follow-up without neurosurgical intervention. Thus, whether or not LSS abnormalities play a role in defecation disorders remains unclear

Rectal Fecal Impaction Treatment in Childhood Constipation: Enemas Versus High Doses Oral PEG

OBJECTIVE: We hypothesized that enemas and polyethylene glycol (PEG) would be equally effective in treating rectal fecal impaction (RFI) but enemas would be less well tolerated and colonic transit time (CTT) would improve during disimpaction. METHODS: Children (4-16 years) with functional constipation and RFI participated. One week before disimpaction, a rectal examination was performed, symptoms of constipation were recorded, and the first CTT measurement was started. If RFI was determined, then patients were assigned randomly to receive enemas once daily or PEG (1.5 g/kg per day) for 6 consecutive days. During this period, the second CTT measurement was started and a child's behavior questionnaire was administered. Successful rectal disimpaction, defecation and fecal incontinence frequencies, occurrence of abdominal pain and watery stools, CTTs (before and after disimpaction), and behavior scores were assessed. RESULTS: Ninety-five patients were eligible, of whom 90 participated (male, n = 60; mean age: 7.5 +/- 2.8 years). Forty-six patients received enemas and 44 PEG, with 5 dropouts in each group. Successful disimpaction was achieved with enemas (80%) and PEG (68%; P = .28). Fecal incontinence and watery stools were reported more frequently with PEG (P <.01), but defecation frequency (P = .64), abdominal pain (P = .33), and behavior scores were comparable between groups. CTT normalized equally (P = .85) in the 2 groups. CONCLUSION: Enemas and PEG were equally effective in treating RFI in children. Compared with enemas, PEG caused more fecal incontinence, with comparable behavior scores. The treatments should be considered equally as first-line therapy for RFI. Pediatrics 2009; 124: e1108-e111
