Usefulness of the ultrathin endoscope with a newly developed knife for complex esophageal endoscopic submucosal dissection

Post written by Satoki Shichijo, MD, PhD, from the Department of Gastrointestinal Oncology, Osaka International Cancer Institute, Osaka, Japan.


A 62-year-old woman underwent subtotal esophagectomy for esophageal cancer, local resection of pharyngeal cancer with postoperative radiotherapy, and bilateral cervical lymph node dissection because of pharyngeal cancer metastasis.

Follow-up endoscopy revealed a 10-mm brownish area in the cervical esophagus, suspicious of neoplasia. Endoscopic submucosal dissection was performed with the patient under general anesthesia because the lesion was located in the cervical esophagus.

However, we could not dissect the posterior and left sides because of the restricted maneuverability of the scope as a result of previous surgery and radiotherapy.

We then switched to an ultrathin endoscope (GIF-XP290N; Olympus, Tokyo, Japan) with a newly developed knife (Endosaber Fine; Sumitomo Bakelite Co, Ltd, Tokyo, Japan) and completed dissection.

We felt it was important to showcase this video to display the usefulness of the ultrathin endoscope with a newly developed knife for a complex situation.
