Abstract

Background

Esophageal SCC is a common cancer worldwide. Major risk factors were tobacco and alcohol use. It’s also a cause of head and neck cancers, particularly hypopharyngeal SCC. ESD was established as standard procedure for curative early esophageal SCC. However, conventional ESD for hypopharyngeal lesions is technically difficult. This report describes a patient who had superficial hypopharyngeal SCC following multiple esophageal ESD sessions. This VDO presentation shows how to perform safe ELPS and achieve oncological purposes.

Methods

A 77-year-old Thai man. He had primary cervical esophageal SCC and 1 month after complete response from definite CCRT, he began presenting four other recurrent episodes of superficial esophageal SCC in the lower, middle, and two times of cervical regions over a 3-year period. ESD and APC were applied and showed a complete response. The last endoscopic finding also revealed of superficial hypopharyngeal SCC and ELPS was decided by the following step: curve laryngoscope placement, laryngeal packing, lesion identification and marking, submucosal injection, circumferential incision, submucosal dissection, and bleeding control. The specimen was removed transorally and sent for pathological examination.

Result

The operation was successful without complications. The patient was able to start a liquid diet on day 1 and a soft meal on second day post operation. He was discharged on 3rd day without any complications. The pathological report was moderated differentiate SCC with positive deep margin, so he was planned for further RT.

Conclusion

ELPS provided good visualization, which led to a sufficient working space for resection. The procedure was safe and feasible for superficial hypopharyngeal lesions and exhibited good oncological outcomes, preserving both swallowing and phonation functions.
