Accessories needed for EMR operation include injection needle, polypectomy snares, hemoclip and ligation device (if applicable) single-use snare probe and spray catheter could be used for both EMR and ESD operations, it also names all-in-one due to its hybird functions. Ligation device could assist polyp ligate, also used for purse-string-suture under endoscop, the hemoclip is used for endoscopic hemostasis and clamping the wound in GI tract and effective staining with spray catheter during endoscopy helps in defining tissue structures and supports detection and diagnosis.

ESD stands for endoscopic submucosal dissection, is an outpatient minimally invasive procedure using endoscopy to remove deep tumors from gastrointestinal tract.

●Superficial lesion in Barrett's esophagus;
●Small gastric lesion ＜10mm, IIa, difficult position for ESD;
●Duodenal lesion;
●Colorectal non-granular/non-depressed ＜20mm or granular lesion.
