Abstract:
Objective To analyze the changes of intestinal hemodynamics in children with abdominal pain accompanied with or without mesenteric lymph node enlargement.Methods From June 2016 to December 2017,in Yuncheng Central Hospital,48 children with abdominal pain and mesenteric lymph node enlargement were randomly selected as the study group,and 49 children with abdominal pain and no mesenteric lymph node swelling were selected as the control group.The end diastolic flow rate,peak systolic flow velocity and resistance index of the SMA were compared by color Doppler ultrasound.Results The end diastolic velocity[(16.46 ± 5.14)cm/s] and peak systolic velocity[(94.89 ±20.15)cm/s]of SMA in the study group were significantly lower than those in the control group [(20.23 ± 6.09) cm/s,(106.98 ± 19.32) cm/s] (t =3.2,3.00,both P ＜ 0.01).There was no statistically significant difference in the SMA resistance index between the two groups [(0.82 ± 0.05) vs.(0.81 ± 0.04)] (t =1.08,P ＞0.05).Conclusion The end diastolic flow rate and peak systolic flow velocity of SMA in children with abdominal pain and mesenteric lymphadenopathy are significantly lower than those with abdominal pain and no mesenteric lymph node enlargement.This shows that the end diastolic flow rate and peak systolic flow velocity of SMA can effectively reflect the changes in the intestinal flow mechanics of the children,which can be used to diagnose the mesenteric drenching in children.It provides a reliable basis for the enlargement of the knot.
