Comparative analyses of short- and long-term outcomes between endoscopic submucosal dissection and endoscopic laryngo-pharyngeal surgery for superficial pharyngeal carcinomas.

There were no differences in batch resection rates or long-term prognoses between the two groups; nevertheless, the ELPS group had a shorter treatment time and less laryngeal edema than the ESD group. However, the treatment of narrow areas, such as the esophageal inlet patch, is a technical limitation of ELPS; thus, ELPS should be combined with ESD techniques.
