Abstract

Introduction: Conjoined twin is an extremely rare condition and requires a thorough knowledge of anatomy, and a multidisciplinary approach is essential to successfully separate the twins. Thoracopagus twins lie face to face and are attached from chest to upper abdomen. They are the most common among all the varieties but have a poor survival rate.

Materials and methods: This study is a review of literature from 2019 to the oldest via PubMed and Google Scholar using keywords: Conjoined twins, Thoracopagus twins, Thoracoomphalopagus and Thoraco-omphalopagus twins. The articles were reviewed for the description of the anatomy of shared organs, management and outcome of these twins.

Results: One hundred and fifty-eight sets of thoracopagus and thoraco-omphalopagus twins including our twins were included in this study. Out of 158 reported thoracopagus twin sets in literature, with M: F ratio of 1:2.3, 71 sets were found to be non-operable and all of them subsequently expired; 82 sets were operated upon, out of which 83 babies survived, suggesting an overall surgical success rate of about 50%.

Conclusion: Thoracopagus twins have a dismal prognosis. The most important decisive parameter for successful separation is the extent of sharing of organs between twins. The role of a motivated multidisciplinary team is also indispensable and cannot be overemphasised.

连体胸腹双胞胎:手术分离的异常和结果的系统回顾。
简介:连体双胞胎是一种极为罕见的情况,需要全面的解剖学知识,而多学科的方法对于成功分离双胞胎至关重要。胸乳症双胞胎面对面躺着,从胸部到上腹部相连。它们是所有品种中最常见的,但存活率很低。材料和方法:这项研究通过PubMed和Google Scholar对2019年至最年长的文献进行了综述,关键词为:连体双胞胎、胸腹双胞胎、胸脐双胞胎和胸脐双胞胎。本文就这对双胞胎共有器官的解剖、处理和结局进行了综述。结果:158对胸脐双生子包括我们的双胞胎被纳入本研究。在文献中报道的158套胸腹双胎中,M:F比为1:2.3,有71套被发现是不可手术的,随后全部过期;共手术82组,其中83名婴儿存活,手术总成功率约为50%。成功分离的最重要决定性参数是双胞胎之间器官共享的程度。一个积极的多学科团队的作用也是不可或缺的,再怎么强调也不为过。
