Paris Classification for GI Polyps

When it activates

Scribeable activates a calculator from the encounter. The Paris Classification for GI Polyps can activate when the transcript or pasted chart context documents any of these:

• GI polyp characterization
• Endoscopic lesion classification
• Polyp morphology assessment
• Endoscopic mucosal resection planning
• Colorectal polyp management decision

Inputs the note needs

1 input. Each is resolved from the transcript, the pasted chart context and charted labs; at this calculator’s tier a missing input is never requested, and a missing required input keeps the score out of the draft.

Scoring

Type 0-I: Polypoid (protruding). 0-Ip: Pedunculated (on a stalk). 0-Is: Sessile (broad-based). Type 0-II: Non-polypoid (superficial). 0-IIa: Slightly elevated (<2.5mm above mucosa). 0-IIb: Flat (no elevation). 0-IIc: Slightly depressed. Type 0-III: Excavated (ulcerated). Combined types possible (e.g., 0-IIa+IIc).

Interpretation

0-Ip: Low submucosal invasion risk — polypectomy with snare. 0-Is: Low to moderate risk — EMR for >=10mm, standard polypectomy for <10mm. 0-IIa: Low risk — EMR or ESD. 0-IIb: Difficult to detect, requires careful inspection with chromoendoscopy; EMR/ESD. 0-IIc: Higher submucosal invasion risk (~30-40% if >10mm) — consider ESD or surgical resection. 0-III: High submucosal invasion risk — surgical resection usually indicated. Combined IIa+IIc or IIc+IIa: Risk depends on depressed component — ESD or surgery. Non-granular lateral spreading tumors (LST-NG) have higher invasion risk than granular (LST-G).

How Scribeable handles it in the note

When an encounter activates the Paris Classification for GI Polyps (its highest tier is recommended), Scribeable does not ask you for missing inputs. The score is computed in code from whatever inputs resolve from the transcript, the pasted chart context or charted labs; a computed value is written into the draft only when every required input already resolves.

The score is computed in code from the resolved inputs, not recalled by the language model. A stated Paris Classification for GI Polyps value is compared against the computed one when the draft's structured summary carries it; a disagreement found there is flagged to the second drafting pass, which is instructed to correct the score and its interpretation, unless Scribeable has supplied the computed value to that pass, in which case the value the draft writes is checked against the supplied one and a detected difference is shown beside the note for you to adjudicate rather than silently rewritten.

Classified as a staging or classification system: activated strictly, because a wrong stage on the wrong patient is a documentation hazard.
