Patients with squamous cell carcinoma (SCC) of the head and neck often develop secondary esophageal carcinomas. We describe a successful case of endoscopic submucosal dissection (ESD) using a transnasal endoscope to treat a patient with esophageal cancer with a pharyngoesophageal anastomotic stricture after total pharyngo-laryngo-esophagectomy (TPLE).

A 60-year-old man was referred to our division for treatment of esophageal cancer. The patient had undergone TPLE for advanced hypopharyngeal cancer 5 years previously, and endoscopy revealed a flat lesion in the lower third of the esophagus ([Fig. 1 a, b]). The patient had a pharyngoesophageal anastomotic stricture after the TPLE that could not be passed using a conventional endoscope ([Fig. 1 c]). Endoscopic balloon dilation was not possible because of the presence of a voice prosthesis ([Fig. 1 d]). Recently, an improved transnasal endoscope, the EG-L580NW (Fujifilm, Tokyo, Japan), has become available, with a 5.8-mm outer diameter and a 2.4-mm forceps diameter ([Fig. 2 a]) [1]. An ultrathin needle-type device (Souten; Kaneka Medics, Tokyo, Japan) and hemostasis forceps (Raicho; Kaneka Medics, Tokyo, Japan) can be used with this endoscope ([Fig. 2 b, c]) [2]. Thus, we performed ESD using a transnasal endoscope to treat the esophageal cancer ([Video 1]).

Circumferential incisions were made using the Souten with Endo Cut I mode (VIO 300D; Erbe, Tübingen, Germany; effect 2, duration 2, interval 2) ([Fig. 3 a, b]). To control bleeding, the Raicho forceps was used in soft coagulation mode at 50 W. Submucosal dissection was performed using the Souten and swift coagulation mode (effect 3, 30 W) ([Fig. 3 c]). Finally, en bloc resection was achieved without injury to the muscularis propria ([Fig. 3 d]). Histological examination revealed R0 resection of the squamous cell carcinoma, which was limited to the epithelium ([Fig. 4]).

Esophageal ESD using a transnasal endoscope was useful in treating esophageal cancer with an anastomotic stricture that could not be passed using a conventional endoscope.
