ABSTRACT
PURPOSE: This study evaluates colon transit time (CTT) and anorectal manometry (ARM) in spina bifida (SB) patients in relation to the level of lesion, mobility, constipation, and continence status. METHODS: SB patients between 6 and 19 years, who are not using antegrade continence enemas and followed at the SB Reference Centre UZ Ghent, were asked to participate. Medical history was retrospectively retrieved from the medical file. Stool habits were prospectively collected using standardized questionnaires. CTT was measured using the 6-day pellet abdominal X-ray method. ARM was performed in non-sedated children with a water-perfused, latex-free catheter. RESULTS: Forty out of 52 eligible patients consented to perform CTT, of which 19 also performed the ARM. Fifteen (37 %) SB patients were constipated despite treatment. Twenty-six (65 %) were (pseudo) continent. The total CTT was significantly prolonged in SB patients (median CTT 86.4 vs. 36 h controls). The CTT was significantly prolonged in constipated SB patients compared to non-constipated SB patients (122.4 vs. 52.8 h). Spontaneously continent patients had a normal CTT (33.6 h) as well as a significantly higher resting pressure compared to the pseudo-continent and incontinent SB patients (resting pressure 56.5 vs. 32.5 mmHg). An abnormal CTT was associated with a treatment necessity to achieve pseudo-continence (p = 0.006). CONCLUSION: CTT in SB patients was significantly prolonged, indicating a neurogenic involvement of the bowel and slow transit constipation. SB patients with a normal CTT and a normal ARM spontaneously achieved fecal continence. CTT can help tailor the continence therapy in SB patients.

PURPOSE: The aims of this study are to describe normal colon transit time (CTT) in healthy children, correlate results with age, the Bristol stool scale, and stool frequency, and to evaluate intra- and interobserver variability. METHODS: Inclusion criteria were as follows: healthy children between 3 and 18 years old with a normal defecation pattern, no history of abdominal surgery, and no medication use. Total and segmental CTT is measured by taking ten polythene radiopaque markers during six consecutive days followed by a single abdominal X-ray on day 7. Total and segmental CTT are calculated by multiplying the number of markers by 2.4 (Abrahamsson et al. Scand J Gastroenterol 32:72-80, 1988). RESULTS: Fifty-four children and adolescents have participated: 30 boys and 24 girls (median age 10 years (3-18 years)). Median total CTT is 36 h (<2.4-86.4 h). There is no significant difference for age category (toddlers 31.2 h (<2.4-74.4 h), elementary school 36 h (2.4-79.2 h), and adolescents 43.2 h (14.4-86.4 h)). Segmental CTT reveals a median right colon CTT of 4.8 h (0-28.8 h); a median left colon CTT of 2.4 h (0-31.2 h); and a median rectosigmoidal CTT of 24 h (0-64.8 h). The Bristol stool scale correlates with total CTT (p = 0.031). The intra- and interobserver variability displays an ICC of 0.999 for the total CTT. CONCLUSION: The CTT of normal healthy children is not sex- or age-related (above the age of 3 years). The Abrahamson method for CTT measurement by using bony landmarks for the determination of colon segments is easy to perform and well tolerated with a virtual inexistent rating difference between different observers.

Epstein-Barr virus (EBV) induced lymphoproliferative disease is a well-known, feared complication of EBV primo-infection in children treated with immunomodulators or immunosuppressive drugs, eg after transplantation. As the incidence of inflammatory bowel disease (IBD) in young children is rising, more young EBV naive patients are treated with immunomodulatory agents. It is not yet clear whether these patients carry the same risk as transplanted patients to develop lymphoproliferative disease and if so, whether their evolution is comparable. We present the history of a young patient with Crohn's disease who developed an EBV related lymphoma shortly after the primo-infection while being treated with azathioprine. This case argues for a rigorous follow up of young IBD patients treated with immune suppressive drugs, also regarding EBV status.

We describe a baby admitted with convulsions, fever, low protein level and coagulation abnormalities where congenital intestinal lymphangiectasia was confirmed by endoscopy and histology. Treatment with a low fat diet, supplemented with medium chain triglycerides (MCT), resulted in a disappearance of the symptoms and normal growth. When confronted with seizure-like attacks, electrolyte disturbances and hypo-albuminemia one should consider the possibility of protein losing enteropathy.
