Hyper-Kvasir Dataset - Coggle Diagram

- - - - anatomical junction between the squamous epithelium of the esophagus and columnar epithelium of the stomach
    - - the endoscope is retroflexed, looking back to visualize the cardia and fundus in the upper parts of the stomach. It includes normal and abnormal types
    - - anatomical junction between the stomach and duodenal bulb. It includes normal and abnormal types
  - - - A (403)
        
        mucosal breaks shorter than 5mm, without continuity across mucosal folds where subtle changes can be difficult to differentiate from a normal Z-line
      - B-D (260)
        
        (C) one (or more) mucosal break that is continuous between the tops of two or more mucosal folds, but which involves less than 75% of the circumference;
        
        (D) one (or more) mucosal break that is continuous between the tops of two or more mucosal folds and involves more than 75% of the circumference.
        
        (B) mucosal breaks longer than 5mm that does not extend between the tops of two mucosal folds;
    - - Long-segment (41)
        
        longitudinal extension of larger than 3 cm
      - Short-segment (53)
        
        longitudinal extension of less than 3 cm
- - - - the distal 2/3 of the small bowel, recognized by visible intestinal villi
    - - the proximal end of the large bowel and is characterized by the visualization of the appendiceal orifice and the ileo-cecal valve
    - - the endoscope is retroflexed in the rectum to visualize the dentate line and the circumference of the proximal orifice of the anal canal
  - - - 0-1 (35) /Grade 1 (201)
        
        Inactive where the mucosa only has normal vascular patterns
      - 1-2 (11) /Grade 2 (443)
        
        Mild with erythema, decreased vascular pattern, mild friability, erosions
      - 2-3 (28) /Grade 3 (133)
        
        Severe with spontaneous bleeding, ulceration
    - - They have mainly three different shapes, protruding in the lumen, flat or excavated, the sizes vary
        from 1 mm to several cm. The prevalence increases with age. :
    - - contains images of polyps lifted with submucosal injection using a solution containing indigo
        carmine. This is done prior to polyp resection.The dye is recognized by the blue color
        underneath the polyp.
    - - After resection of dyed polyps with a snare, the resection margins and site appears blue due to the indigo carmine solution.
    - - pathologically swollen veins in the anus or lower rectum
