Delayed gastric emptying: a novel gastrointestinal finding in Turner's syndrome
Aim:
To evaluate gastric emptying in girls with Turner's syndrome to detect if gastrointestinal motor dysfunction was present.
Subjects:
Thirteen girls (mean age 8.1 years) with Turner's syndrome, seven girls with familial short stature (6.1 years), and eight control girls (7.6 years).
Methods:
Gastric emptying studies were performed by using 500 microCi of technetium 99m-sulphur colloid bound to a scrambled egg, and scintigraphic measurements were made for 60 to 90 minutes.
Results:
Mean (SD) percentage retention of gastric isotope was significantly greater in girls with Turner's syndrome than in children with short stature and in controls. Furthermore, in contrast with control subjects, in whom there was an inverse linear relationship between gastric emptying rate and body mass index, in children with Turner's syndrome the delay in gastric emptying was independent of the body mass.
Conclusions:
The results of the study suggest that delayed gastric emptying is detectable in girls with Turner's syndrome independent of age, body mass index, karyotype, and growth promoting treatment.
