Abstract
The tunnel technique develops rapidly, and promising results have been shown in clinical studies and animal experiments. In this technique, one submucosal tunnel is created to provide working space for further endoscopic interventions, such as cutting the muscularis propria in the treatment of achalasia, removing gastrointestinal submucosal tumors, or even allowing access to the peritoneal and thoracic cavity for further interventions. Since 2009, Professor Enqiang Linghu has attempted to improve ESD procedure by use of tunnel technique, and thus one submucosal tunnel extending from oral margin to anal margin is established to facilitate en bloc resection of the lesions. Tunnel technique has been used to treat esophageal circumferential lesions, large esophageal lesions and gastric large lesions, and proved to be safe and effective, which will be discussed in detail in this chapter. Tunnel technique changes the standard procedure of ESD from marking–injection–circumferential incision–dissection to marking–injection–anal incision–oral incision–tunnel creation–bilateral resection.
