Abstract

OBJECTIVE

The aim of this study was to determine whether tube feeding affects the rate of gastric emptying determined by gastroesophageal reflux scintigraphy in pediatric patients.

METHODS

Gastroesophageal reflux scintigraphy studies of 700 pediatric patients aged 1 week to 16 years were retrospectively analyzed. From these, 350 subjects received their study meal via a feeding tube, and 350 subjects received their meal as oral feeding. Gastric-emptying rate at 60 minutes was calculated, and the results compared. Stratification analysis for age, sex, and type and volume of administered meal was also performed.

RESULTS

The average rate of the gastric emptying was higher in the tube feeding compared with oral feeding group (52.9% ± 17.9% vs 44.2% ± 15.1% gastric emptying at 1 hour, P < 0.01). The prevalence of fast gastric emptying, defined as greater than 50% emptying at 60 minutes, was also higher in the tube feeding group, being registered in 59.7% (209/350 cases) versus only 31.4% (110/350 cases) in the oral feeding group, P < 0.01. The difference persisted following stratification analysis for sex, age, and type and volume of ingested meal.

CONCLUSIONS

Our findings show that tube feeding increases the rate of gastric emptying determined by gastroesophageal reflux scintigraphy in pediatric patients. The effect proved independent on such factors as sex, age, and type or volume of ingested meal.

摘要

目的

本研究旨在确定管饲是否会影响胃食管反流闪烁显像术测定的儿科患者胃排空率。

方法

回顾性分析了 700 名年龄在 1 周到 16 岁的儿科患者的胃食管反流闪烁显像研究。其中，350 名患者通过喂养管接受研究餐，350 名患者经口进食。计算 60 分钟时的胃排空率，并比较结果。还对年龄、性别以及给予的膳食类型和量进行了分层分析。

结果

与口服喂养组相比，管饲喂养组的胃排空平均速度更高（1 小时时胃排空率分别为 52.9%±17.9%和 44.2%±15.1%，P<0.01）。管饲喂养组快速胃排空（定义为 60 分钟时排空量大于 50%）的发生率也更高，为 59.7%（209/350 例），而口服喂养组仅为 31.4%（110/350 例），P<0.01。对性别、年龄以及摄入的膳食类型和量进行分层分析后，这种差异仍然存在。
