Abstract

Introduction

Omphalomesenteric duct cyst (OMDC) is an uncommon remnant of the omphalomesenteric duct. The occurrence of ectopic gastric mucosa within such cysts is rare and may lead to complications due to acid secretion.

Case presentation

A 2-year-old girl presented to us with persistent serous umbilical discharge since birth, associated with severe periumbilical excoriation. Ultrasonography showed a 1-cm cystic lesion beneath the umbilicus. Umbilical exploration revealed a cyst posterior to the umbilicus in the pre-peritoneal space, communicating with the skin through a fine sinus tract. The cyst was excised completely. Histopathological examination demonstrated ectopic gastric mucosa within the cyst wall. Postoperatively, the child had an uneventful recovery and was discharged home the day after the procedure. She remains asymptomatic and the excoriation of the skin has resolved.

Conclusion

Children presenting with persistent umbilical discharge accompanied by severe skin excoriation should be evaluated for an omphalomesenteric duct cyst containing ectopic gastric mucosa.

幼儿含胃粘膜异位的脐肠管囊肿1例报告

摘要肛管囊肿（OMDC）是一种罕见的肛管残余病变。这种囊肿内发生胃粘膜异位是罕见的，并可能因胃酸分泌而导致并发症。病例介绍：一名2岁女童自出生以来持续出现浆液性脐带分泌物，并伴有严重的脐周擦伤。超声示脐下1厘米囊性病变。脐部探查发现一个囊肿位于脐后腹膜前间隙，通过细小的窦道与皮肤相通。囊肿被完全切除了。组织病理学检查显示囊肿壁内胃粘膜异位。术后，患儿顺利康复，并于术后第二天出院回家。她仍无症状，皮肤擦伤已消失。结论儿童持续脐带分泌物并伴有严重的皮肤擦伤，应对伴有胃粘膜异位的脐肠管囊肿进行诊断。
