Gastric emptying of solids in normal children—a preliminary report

Outcomes of pyloroplasty and pyloric dilatation in children diagnosed with nonobstructive delayed gastric emptying

“…The preprocedural study technetium half-life (Tc-99 T 1/2 ) mean was 208 minutes (range, 67-690), the reference range at our institution being 45 to 90 minutes [12,13]. Only 10 patients in our study had postprocedural GS.…”

Validity of 13C octanoic acid breath test for measurement of solid meal gastric emptying time in children

“…In this study, we used a standardized test meal that has proven acceptability in the age groups of children being tested [9]. It is known to be consumed compl etely and deliver the substrate as required.…”

“…It is known to be consumed compl etely and deliver the substrate as required. The test meal is easy to prepare and its compo nents are widely and easily avail able [9].…”

“…A standardized test meal was used (30 g chocolate crispy cake, energy content 616 .72 kJ) [9]. 99 Tc ion exchange resin equivalent to 3 MBq and 100 mg of 13 C-octanoic acid (Cambridge Isotope Laboratories, Mass) were stirred into the chocolate mixture to ensure uniform distribution throughout the product.…”

“…Because of these pitfalls, large-scale studies in normal children are not recommended using this technique. Only 1 study has been performed to establish reference ranges for GE in children involving 25 normal children in whom GE was measured with 99 Tc-lab eled solid meal scintigra phy (GE Tc ) [9]. Because of the small number of children studied, this study is of limited utility.…”
