Abstract
- PURPOSE
To compare US findings of the mesenteric lymph nodes in symptomatic(abdominal pain) and asympto-matic
children and to assess the diagnostic significance of the mesenteric lymph nodes detected on US.
MATERIALS AND METHODS
Fifty children with acute abdominal pain and 50 asymptomatic children were evaluated
for the presence of enlarged mesenteric lymph nodes. The enlarged mesenteric lymph nodes were evaluated for
size, number, location and internal echotexture on sonography. And then the results are statistically analized by
chi-square method.
RESULTS
The short diameter of the lymph nodes that are less than 4 mm in symptomatic group is analyzed
17(34%) and 20(40%) in asymptomatic group and over than 4mm in short diameter is 33(66%) and 30(60%).
The long diameter that is less than 1 cm is 19(38%) and 21(42%). And over than 1cm in long diameter is
31(62%), 29(58%). The number of the lymph nodes that is less than 5 is 13(26%), 13(26%) and that is between
5 and 10 is 25(50%), 33(66%) that is over than 10 is 12(24%), 4(8%). The location that is in periumbilical is
34(68%), 26(52%) and in RUQ is 0, 5(10%) and in RLQ is 15(30%), 16(32%) and LLQ are 1(2%), 3(6%). And
echotexture that is hypoechoic are 25(50%), 31(62%) and mixed echotexture are 25(50%), 19(38%). As the re-sults
of chi-square test, p-value of the all of them are p>0.05 (no statistical significance).
CONCLUSION
Enlarged mesenteric lymph nodes in children with acute abdominal pain or do not represent a non-specific
finding. Sonography is very useful in detecting the lymph nodes but there is no diagnostic significance
in symptomatic or asymptomatic children. So clinical correlation is essentially needed to confirm the final diag-nosis.
