Endoscopic submucosal dissection (ESD) has become the main method for management of superficial esophageal lesions [1]. However, it remains technically challenging and time-consuming for circumferential lesions [2]. The strategies reported for circumferential diseases have operational complexity [2] [3]. Herein, we present an ESD method involving a single, wide tunnel and clip-and-line traction for resection of a large circumferential esophageal neoplasm.
A 68-year-old man with a large circumferential esophageal lesion was referred to our hospital. Magnifying chromoendoscopy suggested a noninvasive squamous cell carcinoma, and biopsy confirmed a high grade intraepithelial neoplasia. Computed tomography detected no nodal or distal metastases. Under multidisciplinary discussion and the patient’s informed consent, esophageal ESD was chosen ([Video 1]).

The patient underwent general anesthesia. A dual knife was used during the whole procedure. First, after lesion marking, anal and oral circumferential incisions were performed successively ([Fig. 1 a–c]). Second, after submucosal injection, a single, wide tunnel was created from the oral side to the anal incision ([Fig.1 d]). The undissected mucosa retracted, reducing the remaining lesion and facilitating the ongoing procedure. Third, a single clip-and-line traction system was applied to two sites on the oral side of the lesion, facilitating the ESD procedure with adequate exposure of the submucosal layer ([Fig. 1 e, f]). Finally, the procedure was successfully performed, with en bloc resection and a procedure time of 96 minutes ([Fig. 1 g, h]). There were no significant intraoperative adverse events. The specimen showed a squamous cell carcinoma, with invasion of the muscularis mucosa and negative margins.

The patient received oral glucocorticoid treatment postoperatively. He developed mild stenosis after 5 weeks, and to date has received three endoscopic dilations up to 13 mm. No recurrence was found at 2 months’ follow-up.
In conclusion, ESD with single, wide tunnel and clip-and-line traction applied to two sites on the oral side of the lesion can facilitate safe and fast resection of large circumferential esophageal neoplasms.
