Example
- Paris morphologic type
- 0-IIc — slightly depressed
Result: Paris type 0-IIc: non-protruding, slightly depressed; higher risk of submucosal invasion.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- 0-I (protruded)
- 0-Ip pedunculated; 0-Is sessile.
- 0-II (non-protruding)
- 0-IIa slightly elevated; 0-IIb completely flat; 0-IIc slightly depressed.
- 0-III (excavated)
- Excavated / ulcerated. Depressed (0-IIc) and excavated (0-III) types carry a higher risk of submucosal invasion.
