An Educational Intervention, the First Step of the Train the Trainer (TTT) Plan, to Improve the Young Endoscopist's Ability to Find the Early Gastric Cancer:Prospective Study With Historical Control

AIM Verified if the first stage of the Train the trainer (TTT)plan could improve the young endoscopist's ability to detect the early gastric cancer（EGC）.

METHOD

1. a retrospective analysis of the ten young endoscopist's painless gastroscopy examination from January 1, 2014 to December 31, 2014. According mainly to the endoscopic report and pateint's History, quantity of gastroscope, gastric cancer and the early gastric cancer.
2. the first step of the train the trainer plan(TTT) activised in March 19-20,2015,which including the diagnosis and operation "hand in hand" teach by Professor Yano Takeshiin,and the case discussion,and so on. Five young endoscopist accepted the TTT plan and the other five not accepted.
3. The five doctors who accepted the TTT do the gastroendoscopy in accordance with the TTT content (for the T1 period),.(1) the patient's name, (2)gender, (3)age,(4)past medical history (Helicobacter pylori<HP>, gastritis, gastric ulcer, oral drug operation, etc.),（5）gastroscope operation time,(6)the location of the lesion- longitudinal (upper, middle and lower),(7) the location of the lesion -circumferential (lessor curvature, Greater curvature, anterior wall, posterior wall),(8) lesion size, (9)conventional white-light imaging (red, white, no change), (10)magnifying endoscopy with narrow-band imaging (EM-NBI) microvascular and mirosurface pattern VS classification system(VSCS) (boundaries, microvascular pattern and microsurface pattern; don't do it), (11)microscopy types (uplift type, flat type, concave type or IIc I/IIa or IIb), (12)histological type (differentiated and undifferentiated type) and (13) pathological (low grade neoplasia, high-level neoplasia etc.). For the treatment of endoscopy submucosal dissection (ESD) patients, further pathological results were recorded after ESD, including the pathology, edge and basal conditions. The other five doctors do the gastroendoscopy as they do before. (300 cases / person)
4. 2-4 TTT activity ;The five doctors who accepted the TTT do the gastroendoscopy in accordance with the TTT content (for the T2-T4 period),.The other five doctors do the gastroendoscopy as they do before.
5. Statistics the number of early gastric cancer have been found by the five young doctors, and how mang gastroscopy they have done.pay attention to The rates of EGC detection.
