目的评估小儿功能性消化不良(FD)的胃排空功能及临床价值。方法采用三维超声VOCAL技术测量30例FD小儿和30例正常小儿不同时点胃体积,计算各自的胃排空时间并进行两组间的比较。经诊断有胃排空延迟的患儿,临床予胃动力药治疗2周后复查,评估其治疗后胃排空功能。结果 (1)FD组胃半排空时间(GET1/2)与正常组GET1/2比较明显延迟(60.7±13.6)min,(50.3±11.4)min,P=0.002。(2)FD组GET1/2与2h胃残留率之间相关性良好(r=0.854,P<0.05)。(3)餐后饱胀、腹痛、早饱、嗳气症状评分与GET1/2均无明显相关性。(4)FD患儿治疗后胃排空功能明显改善(67.7±12.6)min,(53.3±10.2)min,P<0.005。结论三维超声VOVAL技术可用于FD患儿胃排空功能的评价和治疗疗效的评估。
Objective To evaluate the gastric emptying function and clinical value in children with functional dyspepsia (FD). Methods Three-dimensional ultrasound-based VOCAL technique was used to measure the gastric volume in 30 FD children and 30 normal children at different time points. The time of gastric emptying was calculated and compared between the two groups. The diagnosis of delayed gastric emptying in children after clinical treatment of gastric motility drug 2 weeks after the review to assess the gastric emptying after treatment. Results (1) The gastric emptying time (GET1 / 2) in FD group was significantly delayed (60.7 ± 13.6) min and (50.3 ± 11.4) min, P = 0.002 compared with the normal group, GET1 / 2. (2) There was a good correlation between gastric residual rate in GET1 / 2 and 2h group (r = 0.854, P <0.05). (3) postprandial fullness, abdominal pain, early fullness, belching symptom score and GET1 / 2 no significant correlation. (4) The function of gastric emptying in FD children after treatment was significantly improved (67.7 ± 12.6) min, (53.3 ± 10.2) min, P <0.005. Conclusion The three-dimensional VOVAL technique can be used to evaluate the gastric emptying function and evaluate the curative effect in FD children.
