Clinical characteristics, endoscopic findings, histology, surgical methods, and treatment results of patients with surgery.
| | Patient number | Sex | Age (years) | Tumor site (location/circumference) | Sizea of the resected specimen (cm) | Histology | Time of surgery after ER (day) | Cause of surgery | Surgical method | Hospital stay (day) | Results of surgery |

aTumor size was determined by the measurement of the ER specimen.
DSG: distal subtotal gastrectomy; EGCa: early gastric cancer; ER: endoscopic resection; GC: greater curvature; GIST: gastrointestinal stromal tumor; LWR: laparoscopic wedge resection; TLDG: totally laparoscopic distal gastrectomy.
