Effectiveness of acupuncture for treatment of childhood constipation.

The aim of the present study was to examine the influence of acupuncture on chronic constipation in children and to investigate their basal plasma panopioid level and the changes of this treatment. Seventeen children constipated for at least six months were treated by five weekly placebo acupuncture sessions, followed by 10 weekly true acupuncture sessions. Their parents filled a bowel habit questionnaire. Panopioid activity was measured at time 0 and after 5, 10, and 15 acupuncture sessions. The frequency of bowel movements in males increased more gradually compared to females and reached a maximal improvement only after 10 true acupuncture sessions, from 1.4 +/- 0.6/week to 4.4 +/- 0.6/week and females from 1.4 +/- 0.3/week up to 5.6 +/- 1.2/week. The basal panopioid activity was lower in constipated children as compared to the control population and increased gradually up to control level after 10 true acupuncture sessions. This study is the first to describe a successful treatment by acupuncture of constipated children.

Colchicine is an effective treatment for patients with chronic constipation: an open-label trial.

Chronic constipation is a common clinical condition that frequently does not respond to routine therapeutic measures. We hypothesized that colchicine would be effective in this condition because we reported that it stimulates intestinal motility in rats and commonly causes diarrhea in patients taking the drug for either gouty arthritis or Familial Mediterranean fever. We prospectively studied seven patients with chronic constipation who were refractory to medical therapy and treated them with oral colchicine 0.6 mg per os three times a day for eight weeks in an open-label pilot study. During the study, the mean number of spontaneous bowel movements significantly increased (P < 0.05) from 1.7 +/- 0.5 noted during routine therapy of constipation with laxatives and enemas to 6.4 +/- 0.7 per week; mean colonic transit time significantly (P < 0.05) decreased from 58.1 +/- 2.5 to 47.1 +/- 5.0 hr; and symptoms of abdominal pain, nausea, and bloating significantly (P < 0.05) improved during therapy with colchicine. Oral colchicine (0.6 mg three times a day) therapy appears to be an a promising treatment for chronic constipation and a placebo-controlled trial is indicated to confirm these findings.

Pilot study of pathophysiology of constipation among community diabetics.

We aimed to compare gastrointestinal transit and defecatory function in a random sample of people with or without diabetes mellitus in a US community who reported constipation or laxative use. In this pilot study we measured: gastric, small bowel, and colonic transit by scintigraphy; vector manometry of anal sphincters at rest and during squeeze; defecatory dynamics by balloon expulsion test; and scintigraphic measurement of anorectal angle at rest and during defecation. Autonomic function tests were performed in diabetics. Diabetics with constipation had a higher prevalence of abnormal evacuation or prolonged colonic transit during the first 24 hr than controls (P = 0.07): three had prolonged 24-hr colonic transit, and three abnormal evacuation. Among constipated controls, only one had anismus. Overall, diabetics had slower colonic transit during the first 24 hr than nondiabetics (P < 0.05). Community diabetics who experience constipation or use laxatives have a greater prevalence of delayed 24-hr colonic transit or evacuatory dysfunction than community controls.

Cow's milk protein intolerance and chronic constipation in children.

Cow's milk protein (CMP) allergy was investigated in 25 children (age-range 3 months to 11 years) with chronic constipation. A diagnosis of constipation was made on the basis of a history of painful elimination of hard stools for at least 1 month, whether or not associated with a reduced frequency of stools or soiling. The children were evaluated using clinical parameters and the following laboratory tests: total serum immunoglobulin E (IgE); specific IgE (radioallergosorbent test [RAST]) for whole cow's milk, alpha-lactoalbumin, beta-lactoglobulin, and a food group; and skin-prick tests with whole milk, alpha-lactoalbumin, beta-lactoglobulin, and casein. Following the evaluation, the children were submitted to a CMP-free diet for a period of 4 weeks. In seven patients (28%), constipation disappeared during the CMP-free diet and reappeared within 48-72 h following challenge with cow's milk. In two infants a rectal biopsy revealed allergic colitis and they therefore did not undergo the challenge. High serum levels of total IgE were observed in five of the children who showed a clinical improvement (71%), a positive skin-test in two (29%), and detectable specific IgE in two (29%). These results suggest that CMP allergy or intolerance should be considered as a cause of chronic refractory constipation in children, although the underlying mechanism still require further investigation.

Psyllium is superior to docusate sodium for treatment of chronic constipation.

BACKGROUND: Stool softening is a physician's first step in the management of chronic constipation. AIM: To compare stool softening (stool water content) and laxative efficacy of psyllium hydrophilic mucilloid vs. docusate sodium. METHODS: The multi-site, randomized, double-blind, parallel-design study of 170 subjects with chronic idiopathic constipation involved a 2-week baseline (placebo) phase followed by 2 weeks of treatment. The treatment phase compared psyllium (5.1 g b.d.) plus docusate placebo to docusate sodium (100 mg b.d.) plus psyllium placebo. Stools were collected and assessed. RESULTS: Compared to baseline, psyllium increased stool water content vs. docusate (psyllium 2.33% vs. docusate 0.01%, P = 0.007). Psyllium also increased stool water weight (psyllium 84.0 g/BM; docusate 71.4 g/BM; P = 0.04), total stool output (psyllium 359.9 g/week: docusate 271.9 g/week; P = 0.005), and O'Brien rank-type score combining objective measures of constipation (psyllium 475.1; docusate 403.9; P = 0.002). Bowel movement (BM) frequency was significantly greater for psyllium (3.5 BM/week) vs. docusate (2.9 BM/week) in treatment week 2 (P = 0.02), with no significant difference (P > 0.05) between treatment groups in treatment week 1 (3.3 vs. 3.1 BM/week). CONCLUSION: Psyllium is superior to docusate sodium for softening stools by increasing stool water content, and has greater overall laxative efficacy in subjects with chronic idiopathic constipation.

Long-term safety of tegaserod in patients with constipation-predominant irritable bowel syndrome.

BACKGROUND: Tegaserod is a 5-hydroxytryptamine-4 receptor partial agonist. Oral administration causes gastrointestinal effects resulting in increased gastrointestinal motility and attenuation of visceral sensation. AIM: : To determine the long-term safety and tolerability of tegaserod in patients suffering from irritable bowel syndrome with constipation as the predominant symptom of altered bowel habits. METHOD: A multicentre, open-label study with flexible dose titration of tegaserod in out-patients suffering from constipation-predominant irritable bowel syndrome. RESULTS: A total of 579 patients with constipation-predominant irritable bowel syndrome were treated with tegaserod. Of these, 304 (53%) completed the trial. The most common adverse events, classified as related to tegaserod for any dose, were mild and transient diarrhoea (10.1%), headache (8.3%), abdominal pain (7.4%) and flatulence (5.5%). Forty serious adverse events were reported in 25 patients (4.4% of patients) leading to discontinuation in six patients. There was one serious adverse event, acute abdominal pain, classified as possibly related to tegaserod. There were no consistent differences in adverse events between patients previously exposed to tegaserod and those treated de novo. No pattern-forming tegaserod-related abnormalities in haematological and biochemical laboratory tests, urinalysis, blood pressure, pulse rate or electrocardiograms were found. CONCLUSIONS: Tegaserod appears to be well tolerated in the treatment of patients with constipation-predominant irritable bowel syndrome. The adverse event profile, clinical laboratory evaluations, vital signs and electrocardiogram recordings revealed no evidence of any unexpected adverse events, and suggest that treatment is safe over a 12-month period.

Contemporary understanding and management of reflux and constipation in the general population and pregnancy: a consensus meeting.

BACKGROUND: Gastro-oesophageal reflux disease (GERD) and constipation have a major impact on public health; however, the wide variety of treatment options presents difficulties for recommending therapy. Lack of definitive guidelines in pharmacy and general practice medicine further exacerbates the decision dilemma. AIMS: To address these issues, a panel of experts discussed the principles and practice of treating GERD and constipation in the general population and in pregnancy, with the aim of developing respective treatment guidelines. RESULTS: The panel recommended antacids 'on-demand' as the first-line over-the-counter treatment in reflux, and as rescue medication for immediate relief when reflux breaks through with proton pump inhibitors. Calcium/magnesium-based antacids were recommended as the treatment of choice for pregnant women because of their good safety profile. In constipation, current data do not distinguish a hierarchy between polyethylene glycol (PEG)-based laxatives and other first-line treatments, although limitations are associated with stimulant- and bulk-forming laxatives. Where data are available, PEG is superior to lactulose in terms of efficacy. In pregnancy, PEG-based laxatives meet the criteria for the ideal treatment. CONCLUSIONS: The experts developed algorithms that present healthcare professionals with clear treatment options and management strategies for GERD and constipation in pharmacy and general practice medicine.

Permanent sacral nerve stimulation for treatment of idiopathic constipation.

BACKGROUND: Constipation can usually be managed using conservative therapies. A proportion of patients require more intensive treatment. Surgery provides variable results. This paper describes an alternative approach, in which the neural control of the bowel and pelvic floor is modified, using permanent sacral nerve stimulation. METHODS: Four women (aged 27-36 years), underwent temporary and then permanent stimulation. All had idiopathic constipation, resistant to maximal therapy, with symptoms for 8-32 years. Clinical evaluation, bowel diary, Wexner constipation score, symptom analogue score, quality of life questionnaire and anorectal physiology were completed. RESULTS: There was a marked improvement in all patients with temporary, and in three with permanent, stimulation. Median follow-up was 8 (range 1-11) months. Bowel frequency increased from 1-6 to 6-28 evacuations per 3 weeks. Improvement occurred, at longest-follow-up, in median (range) evacuation score (4 (0-4) versus 1 (0-4)), time with abdominal pain (98 (95-100) versus 12 (0-100) per cent), time with bloating (100 (95-100) versus 12 (5-100) per cent), Wexner score (21 (20-22) versus 9 (1-20)), analogue score (22 (16-32) versus 80 (20-98)) and quality of life. Maximum anal resting and squeeze pressures increased. Rectal sensation was altered. Transit time normalized in one patient. CONCLUSION: Permanent sacral nerve stimulation can be used to treat patients with resistant idiopathic constipation.

Study of the motile activity of the colon in rectal inertia constipation.

BACKGROUND: We have recently demonstrated that rectal distension effected left colonic contraction, which probably acts to feed the rectum with fecal matter each time the rectum distends and evacuates its contents. This effect was postulated to occur through the recto-colic reflex. As the colonic status in rectal inertia constipation was scarcely addressed in the literature, we investigated this point. METHODS: The response of the colonic pressure to rectal balloon distension in increments of 10 mL of water was studied in 38 patients with rectal inertia constipation (IC) (age 42.6 +/- 14.3 years, 29 women) and 12 healthy volunteers (40.9 +/- 12.2 years, nine women). The rectal and colonic pressures were measured by saline-perfused tubes connected to a pneumohydraulic infusion system. The rectum was distended by a condom applied to the end of a 10-F catheter. RESULTS: The rectal and left colonic resting pressures were significantly lower in the patients than in the controls (P < 0.5, P < 0.05, respectively). In the healthy volunteers, rectal distension up to first rectal sensation produced no significant rectal or colonic pressure changes (P > 0.05, P > 0.05). At urge, rectal and left colonic pressures increased significantly (P < 0.001, P < 0.001, respectively), but there were no changes in the right colonic pressure (P > 0.05). The colonic response lasted as long as the rectum was distended. In IC, patients did not perceive the first rectal or urge sensation up to a rectal balloon filling of 300 mL; there was no rectal or colonic pressure response (P > 0.05, P > 0.05). CONCLUSION: In normal subjects, left colonic contraction on rectal distension probably acts to feed the rectum with fecal material. In IC, the low left colonic resting pressure assumedly points to left colonic hypotonia which appears to aggravate the constipation produced by the inertic rectum. Furthermore, non-response of the left colon to rectal distension probably impedes rectal feeding with fecal matter and enhances constipation.

Dietary fibre intake and constipation in children with severe developmental disabilities.

OBJECTIVE: Constipation is a common problem in children with severe developmental disabilities (DD). This study aimed to evaluate fibre intake of severe DD children living in a residential institution, and the possibility of reducing the use of laxatives by increasing their fibre intake. METHODOLOGY: A baseline study was performed to evaluate the fibre and macronutrient intake in a group of severe DD children. Nutrients including fibre for a standard serving in each meal were calculated and daily macronutrients and fibre intake were estimated. An intervention study was then carried out to evaluate whether increasing fibre intake could relieve constipation. A total of 20 children aged between 3 and 17 years were assessed over a 4-month period. In a residential unit for severe DD children, laxatives were routinely prescribed if there was no spontaneous bowel motion for two consecutive days. Fibre intake was increased in stages by adding All-Bran(R) (Kellogg Company, Battle Creek, MI, USA) and desserts. The mean number of laxative usage per week per child in the different stages were then compared. RESULTS: The baseline fibre intake was found to be approximately 2 g/day. The mean number of laxatives required per week per child decreased significantly from a baseline value of 1.22 (about 5 laxatives/month) (standard deviation (SD) = 0.36)) to 0.90 (about 3. 5 laxatives/month) (SD = 0.75) in the first stage, and 0.71 (about 3 laxatives/month) (SD = 0.40) in the second stage. Using paired t-test, the difference was statistically significant when compared with the baseline: P < 0.05 for the first, and P < 0.01 for the second stage of fibre supplementation. CONCLUSION: Very low daily intake of fibre of 2 g/day was documented. Relief of constipation and a significant reduction in the usage of laxatives was demonstrated by increasing fibre intake to 17 g/day (stage 1). Increasing fibre intake further to 21 g/day (stage 2), showed a further reduction in the use of laxatives. There was, however, no statistical significance between stage 1 and stage 2 of fibre supplementation. Alternative ways to further relieve constipation in severe DD children require further studies.

Cows milk consumption in constipation and anal fissure in infants and young children.

OBJECTIVE: To examine daily cows milk consumption and duration of breastfeeding in infants and young children with anal fissure and constipation. METHODS: Two groups of 30 consecutive children aged between 4 months and 3 years were evaluated retrospectively. Group I comprised children with chronic constipation and anal fissure in whom surgical causes were excluded, and group II comprised normal children. The daily consumption of cows milk, duration of breastfeeding and other clinical features of the children were investigated RESULTS: The mean daily consumption of cows milk was significantly higher in group I (756 mL, range 200-1500 mL) than group II (253 mL, range 0-1000 mL) (P < 0.001). Group I children were breastfed for a significantly shorter period (5.8 months, range 0-18 months) than group II (10.1 months, range 2-24 months) (P < 0.006). The odds ratios for the two factors - children consuming more than 200 mL of cows milk per day (25 children in group I, 11 children in group II) and breastfeeding for less than 4 months (16 children in group I, 5 children in group II) - were calculated to be 8.6 (95% confidence interval [CI]: 0.23-0.74, P = 0.0005) and 5.7 (95% CI: 0.37-0.66, P = 0.007), respectively. CONCLUSIONS: Infants and young children with chronic constipation and anal fissure may consume larger amounts of cows milk than children with a normal bowel habit. Additionally, shorter duration of breastfeeding and early bottle feeding with cows milk may play a role in the development of constipation and anal fissure in infants and young children.

How do older persons define constipation? Implications for therapeutic management.

This study examined the relation between bowel-related symptoms and self-report of constipation in 10,875 subjects aged 60 years and over, who participated in the 1989 National Health Interview Survey. Subjects reporting constipation "always" or "mostly" over the past 12 months (n = 594) were compared with those who reported never having the symptom (n = 4,192). Straining (adjusted odds ratio 66.7; 95% confidence interval 31.5, 142.4) and hard bowel movements (25.6; 16.7, 38.7) were most strongly associated with self-report of constipation. These findings suggest that treatment for constipation in the older population should be directed as much or more at facilitating comfortable rectal evacuation, as increasing bowel movement frequency.

General geriatrics and gastroenterology: constipation and faecal incontinence.

The incidence of constipation increases with age but no consistent changes of colonic or anorectal motility have been shown in elderly people. Instead, neurological diseases, constipating drugs, bedriddenness and weak straining ability may explain this increased prevalence of constipation. The amount of dietary fibre in the diet may be reduced because of poor chewing ability. Parkinson's disease is accompanied by both slow colonic transit and impaired relaxation of the anal sphincter. Drug-induced constipation is particularly likely with anti-parkinsonism drugs (either anti-cholinergic or dopaminergic) and also with tricyclic anti-depressants, opiates, iron, anti-convulsants and aluminium- or calcium-containing antacids. The prevalence of faecal incontinence is also increased in elderly people. About half of frail bedridden institutionalized patients are incontinent. Anal sphincter pressures tend to be lower, but variables of sensitivity are not. In bedridden people faecal impaction may occur. The ensuing rectal distension leads to relaxation of the internal sphincter and hence to faecal soiling. The condition is often overlooked though correct diagnosis is rather simple, being made with a digital rectal examination.

Predictive value of the balloon expulsion test for excluding the diagnosis of pelvic floor dyssynergia in constipation.

BACKGROUND AND AIMS: The aim of this study was to establish a simple method to exclude the possibility of pelvic floor dyssynergia (PFD) in constipated patients and thus avoid unnecessary expensive physiologic studies. METHODS: Patients with suspicion of functional constipation (FC) were studied prospectively between 1994 and 2002, excluding those with severe systemic, psychological, or symptomatic anorectal/colonic disorders or taking medications that might modify symptoms or results of studies. Diagnosis of PFD was established retrospectively by manometric plus defecographic findings according to Rome II criteria. Two groups of patients were identified: FC without PFD (FC group) and PFD group. A 30-day symptom diary and balloon expulsion test results were evaluated in all patients. Clinical differences and results of the expulsion test were statistically compared between groups. RESULTS: Of 359 patients evaluated, 130 were included (FC group, 106; PFD group, 24). According to data from the diary, only anal pain was more frequent in the PFD group compared with the FC group (anal pain in >25% of defecations, 70.8% vs. 40.6%; P < 0.05, chi(2) test). The expulsion test was pathologic in 21 of 24 patients with PFD and 12 of 106 without PFD. The specificity and negative predictive value of the test for excluding PFD were 89% and 97%, respectively. CONCLUSIONS: The balloon expulsion test is a simple and useful screening procedure to identify constipated patients who do not have PFD. Symptoms are not enough to differentiate between subtypes of constipation.

Biofeedback is superior to laxatives for normal transit constipation due to pelvic floor dyssynergia.

BACKGROUND & AIMS: Uncontrolled trials suggest biofeedback is an effective treatment for pelvic floor dyssynergia (PFD), a type of constipation defined by paradoxical contraction, or inability to relax, pelvic floor muscles during defecation. The aim was to compare biofeedback to laxatives plus education. METHODS: Patients with chronic, severe PFD were first treated with 20 g/day fiber plus enemas or suppositories up to twice weekly. Nonresponders were randomized to either 5 weekly biofeedback sessions (n = 54) or polyethylene glycol 14.6-29.2 g/day plus 5 weekly counseling sessions in preventing constipation (n = 55). Satisfaction with treatment, symptoms of constipation, and pelvic floor physiology were assessed 6 and 12 months later. The biofeedback group was also assessed at 24 months. Laxative-treated patients were instructed to increase the dose of polyethylene glycol from 14.6 to 29.2 g/day after 6 months. RESULTS: At 6 months, major improvement was reported by 43 of 54 (80%) biofeedback patients vs 12 of 55 (22%) laxative-treated patients (P < .001). Biofeedback's benefits were sustained at 12 and 24 months. Biofeedback also produced greater reductions in straining, sensations of incomplete evacuation and anorectal blockage, use of enemas and suppositories, and abdominal pain (all P < .01). Stool frequency increased in both groups. All biofeedback-treated patients reporting major improvement were able to relax the pelvic floor and defecate a 50-mL balloon at 6 and 12 months. CONCLUSIONS: Five biofeedback sessions are more effective than continuous polyethylene glycol for treating PFD, and benefits last at least 2 years. Biofeedback should become the treatment of choice for this common and easily diagnosed type of constipation.

Rectal mucosal biopsy compared with laparoscopic seromuscular biopsy in the diagnosis of intestinal neuronal dysplasia in children with slow-transit constipation.

BACKGROUND/PURPOSE: Intestinal neuronal dysplasia (IND) as a cause for severe chronic constipation remains controversial. The aim of this study is to examine the correlation between a deficiency of substance P (SP) immunoreactive nerve fibers in the colon and enzyme histochemistry of rectal biopsies in children with slow-transit constipation. METHODS: Fifty children with intractable constipation have been assessed by rectal biopsies examined with histochemical staining for lactate dehydrogenase, and 32 children among those 50 have been studied by laparoscopic seromuscular biopsy of the colon labelled with antibodies to SP using immunofluorescence methods. RESULTS: Four children have evidence of IND. Fifteen children, including all 4 IND cases, showed a deficiency of SP immunoreactivity. There is a significant correlation between giant ganglia and SP deficiency (P <.01). CONCLUSION: This study is attempting to propose that a deficiency of SP immunoreactivity in colonic circular muscle nerves may be used as a histologic marker for slow-transit constipation and that IND may be a small subset of patients with SP deficiency.

Posterior sagittal approach: megasigmoid resection and anal reconstruction for severe constipation and fecal incontinence after anoplasty.

PURPOSE: The aim of this study was to present the technique of megasigmoid resection and anal reconstruction by complete posterior sagittal approach for the children with severe constipation and fecal incontinence after anoplasty. METHODS: Six patients (age, 2 to 18 years) born with imperforate anus and originally treated with perineal anoplasty suffered from intractable constipation and fecal incontinence. Contrast enema showed massive dilated and aperistaltic rectosigmoid colon with fecal impaction. Resection of the dilated bowel and anal reconstruction were completely performed by posterior sagittal approach. RESULTS: The mean operating time was 205 minutes (range, 125 to 265 minutes) and the average length of resected colon was 23.3 cm (range, 10 to 40 cm). There were no intraoperative or postoperative complications. By 2 to 4 months after the operation, all patients obtained voluntary bowel movement. On follow-up at 6 to 24 months postoperative, no patient had constipation or required use of the laxatives again. Four of 6 patients suffered from grade 1 soiling, and the other 2 had grade greater than 1 soiling. None had urinary retention or incontinence after the procedure. CONCLUSION: Resection of dilated rectosigmoid colon and anal reconstruction for the patients with severe constipation and fecal incontinence after anoplasty can be performed successfully using a posterior sagittal approach.

Surgical management of chronic unremitting constipation and fecal incontinence associated with megarectum: A preliminary report.

BACKGROUND/PURPOSE: Functional constipation with associated fecal incontinence responds poorly to medical management once megarectum has developed. The authors describe resecting the dilated rectum and inserting a cecostomy button for antegrade enemas in this difficult condition. METHODS: Four children, ages 9 to 15 years, with a history of unremitting constipation and fecal incontinence were referred for evaluation after not responding to medical management. All patients had exhibited normal lumbosacral magnetic resonance images (MRI) and open rectal biopsies; however, all 4 patients had a megarectum on contrast enema. In addition, anorectal manometry was consistent with functional fecal retention. The dilated rectum was resected by anastamosing the nondilated sigmoid colon to the distal rectum, and a standard gastrostomy button was inserted into the cecum for antegrade enemas. Mean follow-up was 35 months (range, 8 to 60 months). RESULTS: Constipation and incontinence resolved within 6 months in all patients, and all children remained continent without the aid of cathartic agents. There were no postoperative episodes of fecal impaction. The only complication was antibiotic-associated diarrhea in 1 patient. Cecostomy buttons were removed at 1 year postplacement in all 4 patients with continued success. Three patients underwent repeat anorectal manometry; all 3 had normal rectal sensory threshold volumes and anorectal inhibitory reflexes. Barium studies also were obtained in the 3 patients without evidence of recurrent rectal dilation. CONCLUSIONS: Refractory constipation and incontinence associated with megarectum may be amenable to surgical intervention in selected patients. The authors' limited experience suggests that proctectomy and button cecostomy is an effective treatment option that improves the quality of life in these patients. Furthermore, proctectomy alone may be curative.
