As the analysis of the literature demonstrates, in spite of a rather wide use of the term "tr. intestinalis" and its inclusion into the PNA, it is still not clear what should be understood under this term concerning the human being. It has been stated, by means of coloured mass injections into the efferent lymphatic vessels of the hepatic, celiac and superior mesenteric lymph nodes, that there is no common efferent lymphatic trunk as a result of fusion of these vessels mentioned above. The efferent lymphatic vessels of the hepatic and celiac lymph nodes terminate in the lumbar lymph nodes; 92.1% of the efferent lymphatic vessels of the superior mesenteric lymph nodes also terminate in the lumbar lymph nodes and only 7.9% of these vessels terminate in the thoracic duct or in one of its roots. Thus, there is no classical lymphatic intestinal trunk (middle root of the thoracic duct) collecting lymph from all abdominal organs and discharging into the thoracic duct.
正如文献分析所示，尽管“肠干”这一术语被广泛使用且被纳入周围神经图谱（PNA），但关于人类而言，该术语具体所指仍不明确。通过向肝、腹腔和肠系膜上淋巴结的输出淋巴管注射有色物质，结果表明上述这些淋巴管并未融合形成共同的输出淋巴干。肝和腹腔淋巴结的输出淋巴管汇入腰淋巴结；肠系膜上淋巴结92.1%的输出淋巴管也汇入腰淋巴结，只有7.9%的淋巴管汇入胸导管或其分支之一。因此，不存在从所有腹部器官收集淋巴并排入胸导管的经典肠淋巴干（胸导管中间根）。
