The omphalomesenteric duct is an embryologic connection between the digestive tract and yolk sac, which typically involutes by the time of birth. Failure of the obliteration process can result in omphalomesenteric duct remnants. We present two cases of children with such remnants, one with an umbilical polyp requiring traditional excisional therapy and one more unusual case of an umbilical cord cyst resolving spontaneously without intervention. The differential diagnosis, which includes urachal remnants and umbilical pyogenic granulomas, is discussed, along with management and special considerations that practioners should be aware of when treating pediatric umbilical and umbilical cord lesions.
卵黄管是消化道与卵黄囊之间的胚胎学连接结构，通常在出生时退化。若闭塞过程失败，可导致卵黄管残留。我们报告两例有此类残留的儿童病例，一例为脐息肉，需行传统切除术治疗；另一例为脐带囊肿，较为罕见，未经干预自行消退。文中讨论了包括脐尿管残留和脐部化脓性肉芽肿在内的鉴别诊断，以及治疗小儿脐部和脐带病变时医生应了解的处理方法和特殊注意事项。
