The Paris classification is the shorthand (0-Ip, 0-Is, 0-IIa and so on) an endoscopist uses to describe the shape of an early growth in the gullet, stomach or bowel, which hints at how deep it may go.
The Paris workshop of 2002 produced an endoscopic classification of superficial neoplastic lesions of the oesophagus, stomach and colon (Gastrointestinal Endoscopy 2003). A review of non-polypoid colorectal lesions (Facciorusso and colleagues, World Journal of Gastroenterology 2015) summarises the flat types: slightly elevated 0-IIa (under 2.5 mm), flat 0-IIb and slightly depressed 0-IIc. Depressed lesions carry a higher risk of invasion into the submucosa even when small, which affects whether a lesion can be removed endoscopically.
