新生儿胃畸胎瘤的诊治探讨

A probe into the diagnosis and treatment of gastric teratoma in neonate

目的探讨新生儿胃畸胎瘤的诊断、治疗与预后。方法对我院病例进行总结并复习相关文献。结果1例新生儿胃畸胎瘤成功手术治疗,病理回报:胃后壁未成熟性畸胎瘤。术后2个月复查AFP定量明显下降。结论胃畸胎瘤非常罕见,生后一天及时诊断未见报道,体检有助诊断,而影像检查(腹部B超、CT)有一定价值,新生儿期大多为良性畸胎瘤,一经诊断,及时手术。彻底切除肿瘤,可不化疗,术后随访,定期复查AFP。

Objective To investigate the diagnosis, treatment and prognosis of gastric teratoma in neonate. Method Analysing one neonatal patient with gastric teratoma and review the literature. Results One case of neonatal gastric teratoma was completely sectioned. Pathological examination showed there is immature teratoma on posterior wall of stomach. Alpha-fetoprotein （AFP） significantly decreased 2 months after surgery. Conclusion Gastric teratoma is rare lesion. There was no such case report of gastric teratoma diagnosed the first day after birth. Careful physical examination is helpful. Image examination （abdominal ultrasound, CT） also contributs to diagnose. Most of neonatal teratoma is benign, which must be immediately sectioned after diagnosis. Immature teratoma can only be treated with thorough section and doesn＇t needs to receive chemical therapy. But such patients need to receive follow up and AFP need to be reexamined at regular time.
