Fetoscopy therapy is one of the signature techniques of fetal medicine. After rapid promotion and development, fetoscopy technology has to some extent become the industry symbol of fetal medicine, the measurement index of fetal medicine center level and the certification label of fetal medicine doctors in China. However, the rapid development has also brought many problems and troubles. Nowadays, the feasibility of large-scale deployment of fetoscopy and the effective use of existing fetoscopy still need to be actively explored. The construction of fetoscopy team and the use of fetoscopy technology still lack normative and authoritative standards. Fetoscopy technology and fetal medicine urgently need to be better understood by the medical community and society. In addition, how to carry out the scientific research on fetoscopy and its related techniques is also an important topic worth exploring.
