Clinical value of three-dimensional ultrasound VOCAL in evaluation of gastric emptying function in children with functional dyspepsia / 中国基层医药

ABSTRACT

Objective@#To evaluate the clinical value of three-dimensional ultrasound VOCAL technique in evaluating gastric emptying function in children with functional dyspepsia (FD).@*Methods@#Seventy-one children with FD who were treated in Wenzhou Integrated Traditional Chinese and Western Medicine Hospital Affiliated to Zhejiang University of Traditional Chinese Medicine from January 2018 to June 2018 were enrolled as the study subjects (observation group), and 71 normal children without FD were selected as controls (control group). The gastric emptying, antral pyloric systolic contraction frequency and distal gastric contraction movement in different time groups were analyzed, and GET1/2 and 2h gastric residual situation before and after treatment in the observation group were compared.@*Results@#The GET1/2 of the observation group was (60.2±12.69)min, and the gastric emptying rate of the observation group was (61.9±12.2)min and (72.0±12.3)min at 90min and 120min, which were significantly better than those of the control group, and the differences were statistically significant (t=19.092, 15.092, 14.882, P=0.016, 0.024, 0.033). The frequency of antral pyloric systolic contraction, gastric antrum contraction frequency and gastric antrum contraction amplitude were (1.1±0.7)times/min, (2.9±0.8)times/min, (1.0±0.6)cm, respectively.Compared with the control group, the differences were statistically significant (t=16.092, 21.224, 8.092, all P<0.05). In the observation group of 71 children GET1/2 before treatment and after treatment were (68.1±11.8)min, (54.2±9.8)min, respectively.The gastric residual at 2h after treatment was (31.2±8.0)%, (22.1±7.0)%, respectively.The GET1/2 and 2h gastric residual rate of the children were significantly lower than before treatment, and the differences were statistically significant (t=18.983, 21.004, all P<0.05).@*Conclusion@#Three-dimensional ultrasound VOCAL technology can be used as an evaluation standard for FD in children.
