 Performing ESD(endoscopic submucosal dissection)on the Ce(cervical esophagus)is difficult owing to the narrow space and poor maneuverability in the Ce. However, a curved laryngoscopy can increase the effective working space, thus allowing for better ESD in the Ce.

 There are several risk factors contributing to severe stricture following esophageal ESD. One such risk factor is the location within the Ce, which is largely due to the narrow diameter of the Ce. Some procedures, such as steroid injection or oral intake, have been reported to be effective for preventing severe stricture following semi-circumferential ESD. However, the effects are not sufficient for use in circumferential ESD, particularly in cervical esophageal ESD.

 Here, we report on a method of ESD for CeSCC(cervical esophageal squamous cell carcinoma)and a complication of endoscopic balloon dilatation following circumferential ESD for CeSCC. Finally, we report on a case wherein 10 synchronous CeSCCs were performed and was then successfully treated with a two-step ESD without severe stricture. Thus, a two-step ESD may be a promising option for preventing severe stricture, particularly for cases with synchronous lesions. However, severe fibrosis arising from the first ESD may cause the mucosal incision and submucosal dissection in the second ESD to become more difficult. Therefore, such difficult ESDs should be performed only by expert endoscopists.
