Background: Lymphedema in the lower abdomen and genitals is unnoticeable and has no established diagnostic methods. In this study, we evaluated it using four examinations. Methods: We evaluated 25 patients with lymphedema in the legs, dividing the abdomen and genitals in four areas (right and left, upper and lower). The mean age was 58.6 years. In lymphoscintigraphy and indocyanine green (ICG) lymphography, we diagnosed lymphedema when dermal backflow was observed. ICG lymphography was performed in 13 patients. In ultrasonography, we determined the presence of edema when cobblestone pattern was observed. Subcutaneous fat thickness was also measured. The patients' subjective symptoms were identified on an interview. We compared the results among the examinations. Results: The positivity rates for lymphedema based on lymphoscintigraphy, ICG lymphography, ultrasonography, and subjective symptoms were 45.0%, 42.3%, 8.0%, and 34.0%, respectively. Two of the 13 patients who underwent all examinations complained of subjective symptoms of edema in areas that showed no abnormalities in the examinations. In contrast, 14 of the 25 patients had areas where they had no subjective symptoms despite having abnormalities in at least one of the tests. Those with subjective symptoms of edema tended to have thinner abdominal fat in both the upper and lower abdomen, but no significant difference was observed. Conclusion: Large differences were observed in the positive rate of edema in subjective symptoms and examinations of lymphedema in the lower abdomen and genitals. It is not important to determine which examination is best but rather to combine multiple examinations. [ABSTRACT FROM AUTHOR] |
