Gastroscopy: F, 65 Medical history: Autoimmune metaplastic atrophic gastritis (AMAG) Location: body of stomach Morphology: 0-ІІа Optical diagnosis: neuroendocrine tumours (NET) Treatment: EMR Pathology report: NET, G2 (ICD-O code: 8249/3) #GITwitter

Colonoscopy (M, 46y.o.) with AI+TXI+NBI+zoom Sigmoid colon Size - 5mm Morphology - 0-ІІа Pit pattern - IIIL NBI - JNET2A Optical diagnosis: tubular adenoma Treatment - cold snare polypectomy Pathology report - tubular adenoma (ICD-O code: 8211/0) (complete removal) #GITwitter

"One stalk two polyps" Sometimes you have to be very careful, because on one stalk can have two polyps. As in this case, we have two separate tubular adenomas. It is very important to place the polypectomy snare correctly. with Ivan_Hornik #GITwitter

Colonoscopy (F, 57y.o.) - TXI+NBI, zoom x135 Location - transverse colon Size - 35mm Morphology - 0-ІIa+IIc, LST-NG Pit pattern – IIIL+Vi+Vn NBI - JNET2A (most part of the polyp) + JNET3 (3mm part of polyp) Optical diagnosis: tubular adenoma + invasive cancer #GITwitter

Female, 25y.o., without complaints. Zoom endoscopy with NBI indicates an absence of microsurface and corkscrew microvascular patterns. Histology - poorly cohesive carcinoma (ICD-O code: 8490/3) #GITwitter #gastric_cancer

66 y.o male came in for a screening colonoscopy. In the ascending colon Paris 0-II-a lesion up to 15mm was visualised. Acetic acid chromoscopy was performed. Share your thoughts on optical diagnosis in the comments. #endoscopy #CancerPrevention

Screening colonoscopy (M, 51y.o.) Location - rectum Size ~ 20mm Morphology: Paris 0-Is type, (LST-G) Pit pattern – IIIL+IV NBI – JNET2A Optical diagnosis: tubulovillous adenoma with LGD Treatment – endoscopic mucosal resection (EMR); Red Dichromatic Imaging (RDI) was very useful

With years of research and development endoscopy equipment has gone from fiber optic to ultra-high magnification endoscopes with artificial intelligence (AI). It allows endoscopists to detect polyps, especially adenomas at the earliest possible stages. Which leads to a
