Gastric emptying in infants with or without gastro-oesophageal reflux according to the type of milk.
The present study was design ed to determine the effects of milk composition and the influence of  gastro-oesophageal reflux ( GOR )  on gastric emptying .  Cineoesogastrocintigraphy ( COGS ) was performed in 201 infants between 0 - 1 year of age in order to detect GOR , and provided a means of estimation of the gastric emptying ( GE ) .  Ninety infants appeared free from GOR and constituted the control group ; 111 had GOR . There infants were fed human milk or various st and ard formulae . In addition , 20 infants fed a whey-hydrolysate formula were tested . An appropriate volume of milk was marked with sulfur-colloid Tc ( 200 microcuries ) . Measurements of gastric radioactivity were made 30 min and 120 min after ingestion . For the whole population , the infants with GOR had slightly more rapid GE after 30 min ( P less than 0.05 ) , but , for the same type of milk , there was no significant difference between GOR and controls . GE did not differ with age or sex , but differed mainly according to the type of milk . In the control group , gastric residual content ( GRC ) at 120 min was 18 + /- 11 per cent with human milk ( n = 7 ) , 16 + /- 21 per cent with whey-hydrolysate formula ( n = 8) , 25 + /- 17 per cent with acidified formula ( n = 13 ) , 26 + /- 19 per cent with whey-predominant formula ( n = 22 ) , 39 + /- 17 per cent with casein-predominant formulae ( n = 20 ) , 47 + /- 19 per cent with follow-up formulae ( n = 16 ) and 55 + /- 19 per cent with cow 's milk ( n = 12 ) .
