Purpose: Fecal incontinence is a major problem in patients with myelomeningocele. We evaluate the results of a stratified approach aimed at obtaining fecal pseudo-continence in patients with myelomeningocele. Materials and Methods: We conducted a cross-sectional descriptive study of last file data in 80 patients 5 to 18 years old with myelomeningocele followed at our center. Beginning at birth patients with myelomeningocele were seen at least annually by the pediatric gastoenterologist, a member of the multidisciplinary “spina team.” Constipation was treated with diet and osmotic laxatives. Starting at age 5 years, treatment was targeted at achieving pseudo-continence. A toilet training scheme was started, associated with induced defecation by digital stimulation. Retrograde tap water enemas were used in patients with unsatisfactory results. If retrograde enemas were unsuccessful, an antegrade continence enema procedure was proposed. For children unable to sit on a toilet regular manual evacuation of stools was advised. Results: Eight of the 80 patients were fecal continent. Pseudo-continence was achieved in 50 of the 72 incontinent patients (69%), including 5 of 5 following only a strict toilet scheme, 21 of 24 (87.5%) performing retrograde enemas, 16 of 20 (80%) performing orthograde enemas through an antegrade continence device and 8 of 10 performing regular manual evacuation of stools. In 4 of the 20 patients (20%) performing orthograde enemas complications led to closure of the antegrade continence device. Treatment failed and was stopped in 17 patients. Success of treatment was not related to level of spinal lesion or degree of mobility. Conclusions: Fecal pseudo-continence was achieved in 58 of 80 patients (72.5%) with myelomeningocele.

Study design: Systematic review. Objectives: To determine the different treatment modalities aimed at achieving fecal continence in spina bifida (SB) patients and their effectiveness. Setting: International literature. Method: Electronic databases were searched (‘Pubmed’, ‘Web of science’, ‘CINAHL’ and ‘Cochrane’) identifying studies published since the mid-eighties and screened for relevance according to the Centre for Reviews and Dissemination procedure guidelines. A total of 37 studies were selected for inclusion. Results: Studies on toilet sitting, biofeedback, anal plug, retrograde colon enemas (RCE) and antegrade colon enemas were found. Fecal continence was achieved in 67% of SB patients using conservative methods (n=509). In patients using RCE (n=190) an 80% continence rate was reached. Patients following surgical treatment (n=469) reached an 81% continence rate, however, 23% needed redo surgery because of complications. Better fecal continence was associated with an improved quality of life, which was negatively influenced by the amount of time spent on bowel management. Conclusion: Evidence favors an individually tailored stepwise approach with surgery as a final step in case of failure of conservative measures. Continued specialized support throughout life remains important to maintain continence. Cross-over and comparative trials are needed in order to optimize treatment.

Assess the risk of zinc (Zn) deficiency in the older cystic fibrosis (CF) population. Cross-sectional investigation of all CF patients above the age of 4 followed at the Ghent University center between 2002 and 2003. Data on age, weight, height z-score, pancreatic and pulmonary functions, chronic Pseudomonas infection, and CF transmembrane conductance regulator (CFTR) mutations were collected. Serum Zn, vitamins (vit) A and E, retinol-binding protein (RBP), albumin, sedimentation rate, total IgG, and cholesterol were determined. Serum Zn was compared with a local healthy control group (Van Biervliet et al., Biol Trace Elem Res 94:33–40, 2003) and with literature data (Hotz C, et al. Am J Clin Nutr 78:756–764, 2003). 101 patients (median age 16 years) were included. There was no difference in serum Zn concentration between CF patients and controls. In CF patients no difference in serum Zn concentration between pancreatic-sufficient or pancreatic-insufficient patients was seen. Serum Zn was not associated to nutritional status or height z-score. A significant association serum Zn to serum albumin (p < 0.0005) and to vit A (p < 0.01) was seen. No associations of serum Zn to serum vit E, RBP, cholesterol, or CFTR were present, but there is a significant association serum Zn to forced vital capacity (p < 0.01). Serum Zn was not associated to inflammatory parameters or chronic Pseudomonas infection. Comparison of CF patients with local controls revealed no significant differences. However, because persisting steatorrhea increases Zn loss (Easley et al., J Pediatr Gastroenterol Nutr 26:136–139, 1998) and 12.6% of our population has a serum Zn below the p value of 2.5 of the NHANES II study (Hotz C, et al. Am J Clin Nutr 78:756–764, 2003), there could remain an increased risk of Zn deficiency in some CF patients. Furthermore, the association with pulmonary function needs more investigation.

We studied the use of colon enemas in achieving fecal pseudocontinence in patients with spina bifida to define the variables associated with success. Questionnaires were individually filled out by all patients with spina bifida using colon enemas at our Spina Bifida Reference Center between October 2009 and June 2010. Patient age, type of enema, volume required, evacuation time, followup, continence and independence were recorded. Fecal pseudocontinence was defined as no involuntary stool loss during the last 6 months. Social continence was defined as involuntary stool loss less than once monthly. Children are routinely seen at the reference center, while adults are seen on request. A total of 25 children and 15 adults with spina bifida were studied. Median volume required was 1 liter (range 0.5 to 2) in children and 1.5 liters (0.75 to 3) in adults. Median evacuation time was 30 minutes (range 15 to 60) in children and 60 minutes (30 to 120) in adults. Fecal continence was achieved in 76% of children (19 of 25) and 60% of adults (9 of 15), and social continence in 88% of children (23 of 25) and 67% of adults (10 of 15). A significant relation was found between medical followup since childhood and fecal pseudocontinence. No enema determinants predicted pseudocontinence. Colon enemas are a valuable method in achieving continence. At our center medical followup from childhood to adulthood is associated with successful acquisition of fecal pseudocontinence.
