Nonstricture cases administered steroid pulse therapy after esophageal ESD.
| Case | Sex | Age (yr) | Location | Mucosal defect circumference | Longitudinal resected specimen size (mm) | Tumor depth |
|---|---|---|---|---|---|---|
| 1 | M | 75 | Lt | 1/2–<3/4 | 50 | MM |
| 2 | M | 60 | Lt | ≥3/4–<7/8 | 50 | LPM |
| 3∗ | M | 63 | Mt | ≥7/8 | 111 | 1 SM2, 2 EP |
| 4 | M | 70 | Mt | ≥3/4–<7/8 | 53 | EP |
| 5 | M | 83 | Lt | 1/2–<3/4 | 52 | EP |
∗In case 3, three lesions were completely resected in one piece. ESD: endoscopic submucosal dissection; Mt: middle thoracic esophagus; Lt: lower thoracic esophagus; EP: epithelium; LPM: lamina propria mucosa; MM: muscularis mucosa; SM2: deep submucosal invasion (greater than 200 μm from MM).
