Lap Chole Complete Process Prompt

Adapter for ChatGPT/OpenAI image models: keep instructions explicit, avoid dense text inside the image, and prioritize clean publication layout.

MAIN PROMPT:
SYSTEM_INSTRUCTION_MODE: SURGICAL_ANATOMY_ACADEMIC

Topic: laparoscopic cholecystectomy complete surgical process diagram
Task type: surgical illustration
Visual style: NEJM-style clinical figure
Style cues: publication-grade medical illustration, muted academic palette, soft airbrushed tissue rendering, thin precise dark-grey outlines, off-white background, clean journal figure composition.
Composition: 6-panel procedure storyboard following the exact panel plan below; do not compress this procedure into four panels.
Background: clean white or off-white publication background.
Rendering: non-gory, atraumatic, didactic, anatomy-first medical illustration.

## NON-NEGOTIABLE ANATOMY RULES
- Anatomy correctness outranks visual style.
- Preserve left/right, medial/lateral, superior/inferior, and anterior/posterior relationships.
- Do not invent vessels, ducts, nerves, tissue planes, or operative steps.
- If a structure is uncertain, simplify or omit it rather than labeling it incorrectly.
- Keep surgical instruments simplified unless instrument position is the teaching point.

## TEMPLATE: lap_chole
- Core safety concept: Achieve the Critical View of Safety before dividing any duct or artery; if CVS cannot be achieved, depict a bail-out concept rather than unsafe division.
- Orientation / laterality: Right upper quadrant; gallbladder on the inferior surface of liver segments IVb/V
- Must show: Gallbladder fundus, body, infundibulum/neck, and inferior liver edge.
- Must show: Cystic duct, common hepatic duct, common bile duct, cystic artery, and right hepatic artery relationship.
- Must show: Hepatocystic triangle / Calot triangle shown as a real anatomic space, not a decorative outline.
- Must show: Critical View of Safety panel with lower gallbladder separated from the liver bed.
- Spatial anatomy rules: Cystic duct joins the common hepatic duct to form the common bile duct.
- Spatial anatomy rules: Cystic artery lies in or near the hepatocystic triangle and approaches the gallbladder neck.
- Spatial anatomy rules: Only cystic duct and cystic artery should enter the gallbladder before division.
- Spatial anatomy rules: Common bile duct remains continuous and untouched in clip/divide panels.
- Forbidden mistake [critical]: Common bile duct clipped or divided.
- Forbidden mistake [critical]: Cystic duct confused with common bile duct.
- Forbidden mistake [major]: A third duct shown entering the gallbladder in the CVS panel.
- Forbidden mistake [major]: Cystic artery placed far outside the hepatocystic triangle without explanation.

## LABEL TERMINOLOGY
- Gallbladder
- Cystic duct
- Common hepatic duct
- Common bile duct
- Cystic artery
- Right hepatic artery
- Hepatocystic triangle / Calot triangle
- Liver edge
- Critical View of Safety
- Lower gallbladder dissected from liver bed

## PROCEDURE PANEL PLAN
- Required panel count: 6
- Use all listed panels unless the user explicitly requests a shorter figure.
- Do not replace this plan with a generic four-panel storyboard.
- Port/instrument context and gross anatomy.
- Gallbladder exposure and fundus/infundibulum retraction to open the hepatocystic triangle.
- Dissection and clearing of the hepatocystic / Calot triangle.
- Critical View of Safety verification: only cystic duct and cystic artery enter the gallbladder; lower gallbladder separated from the liver bed.
- Clip and divide the cystic duct and cystic artery; common bile duct untouched.
- Gallbladder separation from the liver bed and specimen extraction.

NEGATIVE PROMPT:
low quality, bad anatomy, mirrored anatomy, invented anatomy, blurry labels, text artifacts, messy handwriting, overlapping lines, garish colors, cartoon gore, blood splatter, watermark

POST-GENERATION CHECK:
- Verify anatomy positions, proportions, orientation, and layer relationships.
- Cystic duct joins the common hepatic duct to form the common bile duct; CBD continuous and uninstrumented.
- Cystic artery lies within the hepatocystic triangle.
- CVS panel shows only two structures entering the gallbladder and the lower third off the liver bed.
- No extra/third duct entering the gallbladder.
- Non-gory and publication-appropriate.
- Confirm no invented ducts, arteries, veins, nerves, or operative steps are shown.
- Check labels and leader lines do not obscure critical anatomy.
