摘要

目的:探讨放射性核素显像对肥胖患者腹股沟淋巴结滤过的潜在影响。我们的目的是比较肥胖患者和正常体重个体的腹股沟淋巴结后淋巴运输,同时确保完整的下肢淋巴流动。方法:采用回顾性研究设计,包括对患者图像的重新评估。119例患者中,62例为肥胖,其余患者体重指数均在正常范围内。纳入研究的所有患者均为女性,平均年龄39岁(28 - 47岁)。采用tc -99m标记的50-70 nm纳米胶体颗粒进行淋巴显像。将纳米胶体应用于双脚背部的第1和第2指间网区域。应用后45-50分钟和2小时采集后期图像。结果:119例患者中,62例(52%)为肥胖。两组在年龄方面没有显著差异。从腹股沟淋巴结前计数计算的腹股沟前平均计数值在两组之间没有显着差异。然而,肥胖患者的腹股沟淋巴结术后平均计数值明显低于正常体重患者(p<0.0005)。结论:我们的研究结果表明,即使在早期,当功能成像可以观察到主要淋巴管时,肥胖患者和正常体重者之间的淋巴管流动进展也存在差异。检测这些差异可以使淋巴水肿疾病的早期诊断,这是一种可逆的疾病,如果及时发现。

Effect of Obesity on Lymphatic Fluid Filtration in Inguinal Lymph Nodes
Objective: The objective of this study was to investigate the potential impact of radionuclide imaging on filtration in the inguinal lymph nodes of obese patients. We aimed to compare the lymphatic transport after the inguinal lymph nodes between obese patients and normal-weight individuals, while ensuring intact lower extremity lymphatic flow. Methods: A retrospective study design was employed, involving the re-evaluation of patient images. Among the total of 119 patients, 62 were classified as obese, while the remaining patients had body mass indexes within normal limits. All patients included in the study were female, with a mean age of 39 years (ranging from 28 to 47 years). Lymphatic imaging was performed using Tc-99m-labeled nanocolloid particles with a size of 50-70 nm. The nanocolloid was applied to the 1st and 2nd interdigital web areas on the dorsum of both feet. Late images were captured at 45-50 minutes and 2 hours after application. Results: Out of the 119 patients, 62 (52%) were classified as obese. There was no significant difference in terms of age between the two groups. The pre-inguinal average count values, calculated from the counts before the inguinal node, did not show a significant difference between the two groups. However, the post-inguinal average count values obtained after the inguinal nodes were significantly lower in obese patients compared to normal-weight patients (p<0.0005). Conclusion: Our findings suggest that even in the early stages, when functional imaging allows observation of the main lymphatic duct, there are differences in the progression of lymphatic flow between obese patients and normal-weight individuals. Detecting these differences may enable early diagnosis of lymphedema disease, which is a reversible disorder if identified promptly.
