Up-to-date advanced endoscopy of upper GI neoplasm
Advanced diagnostic and therapeutic endoscopy is developed and widely accepted in Japan. Endoscopic submucosal dissection (ESD) is technically more demanding than endoscopic mucosal resection (EMR). However, it allows for en bloc resection regardless of lesion size and location. Some adverse events have been resolved by the development of novel devices, techniques, and prophylactic procedures. Moreover, several papers reported excellent short and long-term ESD outcomes for superficial esophageal squamous cell carcinoma and early gastric cancer. ESD is now acceptable minimally invasive treatment options, and some Japanese guidelines were published and revised.
Moreover, the ESD technique consisting of mucosal incision and submucosal dissection has been utilized for more advanced surgical resection, such as laparoscopic and endoscopic cooperative surgery (LECS) for gastric submucosal tumor and hybrid endoscopy-assisted larynx preserving esophagectomy for cervical esophageal cancer.
This lecture will overview the up-to-date advanced endoscopy for upper GI neoplasms.
