Electronic endoscope is one of the crucial tools for minimally invasive diagnosis and treatment. Along with the continuous development of clinical applications, conventional electronic endoscope has not been able to meet all the clinical requirements. In recent years, with the rapid development of the material, sensor and electronic technologies, electronic endoscope has attracted many researchers and companies' attention. Nowadays, because of being suitable for some special mobile medical scenes like field operations, natural calamities and hospital first aids, various portable electronic endoscopes have been developed and applied in clinic. The present study aims to give a review on portable electronic endoscopes development and clinical applications.
