Progress in the treatment of early gastric cancer with Laparoscopic and endoscopic cooperative surgery

Abstract

With the introduction of minimally invasive methods into the field of surgery, the concept of early gastric cancer (EGC) treating has gradually changed from the pursuit of standardized traditional surgical methods to precise, individualized, interdisciplinary collaborative management. Both endoscopic therapy and laparoscopic surgery have their limitations for early gastric cancer treatment. Meanwhile, Laparoscopic and endoscopic cooperative surgery (LECS) combines the advantages of endoscopy and laparoscopy to perform local gastric resection and regional lymph node dissection, providing a more effective surgical approach for radical resection of early gastric cancer. The application of LECS in the treatment of early gastric cancer has been increasing, from the initial laparoscopy-assisted endoscopic full-thickness resection to the evolvement of a variety of improved procedures such as combined laparoscopic and endoscopic approach for neoplasia with a non-exposure technique, non-exposed endoscopic wall-inversion surgery, and the possibility of combined (sentinel lymph node drainage area) regional lymph node dissection or sentinel lymph node navigation surgery, which expands the indications for endoscopic surgery and maximizes the preservation of normal gastric tissue structure and function while ensuring radical treatment, and will certainly become an important development direction in the treatment of early gastric cancer in the future.
