According to the MELD, GBS and AIMS65 scoring system, the corresponding scores of each patient were calculated to evaluate the ability of the three scoring systems to correctly classify EGVB as a \" high-risk patient\" . The receiver operating characteristic curve was drawn to compare the predictive value of three scoring systems for different clinical outcomes (blood transfusion, rebleeding, and death).

The images were divided into two datasets, one dataset included in vitro, in vivo and unqualified colonoscopy images, and another dataset included ileocecal and non-cecal area images. And then 3 594 and 2 000 images were selected respectively from the two datasets for testing the deep learning model, and the remaining images were used to train the model.

One had underlying long-segment Barrett esophagus (LSBE), 6 had short-segment Barrett esophagus (SSBE), and 6 had super short-segment Barrett esophagus (less than 1 cm). Two arose from circumferential Barrett esophageal (BE) and 11 from tongue-like BE. Ten lesions were located on the right anterior side wall (12-2 o′clock) of the esophagogastric junction (EGJ), and 12 lesions were superficial type (0-Ⅱ). ESD was successfully conducted in all the patients without any complication. The en bloc and curative resection rate was 100% (13/13) and 92% (12/13), respectively.

ESD is a safe and efficient treatment for BEA. \u0000 \u0000 \u0000Key words: \u0000Barrett esophagus; Adenocarcinoma; Clinical feature; Endoscopic feature; Pathologic feature; Endoscopic submucosal dissection","PeriodicalId":10072,"journal":{"name":"Chinese Journal of Digestive Endoscopy","volume":"37 1","pages":"83-87"},"PeriodicalIF":0.0,"publicationDate":"2020-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47346695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Success rate of ERCP and incidence of complications were analyzed. \u0000 \u0000 \u0000Results \u0000The 99 cases of liver cirrhosis were mainly caused by hepatitis B virus infection (40.4%, 40/99) and unknown reasons (30.3%, 30/99), and the mean model for end-stage liver disease score was 15.4±5.3. The common bile duct stones and bile duct stricture were the most common biliopancreatic diseases, accounting for 49.5% (49/99) and 33.3% (33/99), respectively. The success rate of ERCP was 100.0%(99/99). The total postoperative complication incidence was 14.1% (14/99), among which liver cirrhosis-related complications was 3.0% (3/99); ERCP-related complications was 11.1% (11/99), including 9.1% (9/99) biliary tract infection, and 2.0% (2/99) delayed bleeding.

The general information of the subjects were collected, including name, age, gender, the number of gastroscopy and colonoscopy independently performed before training, the independent usage of narrow band image (NBI), magnifying endoscopy (ME), endoscopic mucosal resection (EMR), ESD, endoscopic ultrasonography (EUS), and endoscopic retrograde cholangiopancreatography (ERCP) before training. And then every trainee independently finished four in vitro experiments of pig esophagus ESD. The specimen area and operating time were recorded, and the operating speed was calculated. Linear regression analysis was used to analyze the affecting factors of operating speed of ESD. \u0000 \u0000 \u0000Results \u0000Among the 41 trainees, 26 were male and 15 were female, with age of 36.07±4.44 years. The specimen area, operating time and operating speed of pig esophagus ESD was 4.67±1.61 cm2, 24.54±5.97 min, and 0.19±0.05 cm2/min, respectively. Univariate linear regression analysis showed that the number of gastroscopy (n>5 000, P=0.001 8) and colonoscopy (n>3 000, P=0.000 1), the detect number of early cancer in upper digestive tract (n>30, P=0.000 3) and lower digestive tract (n>10, P=0.019 7), and the usage of ME (P=0.047 8), EMR (P=0.019 6) and ESD (P=0.000 3) before training were statistically correlated with the operating speed of ESD. Carrying out NBI (P=0.532 9), ERCP (P=0.500 7) and EUS (P=0.766 8) before training were not statistically correlated with the operating speed of ESD. The operating speed of ESD was negatively correlated with the perforation rate of ESD (P<0.000 1). According to multivariable linear regression model, the usage of EMR (P=0.029) and ESD (P=0.034) were statistically correlated with the operating speed of ESD. \u0000 \u0000 \u0000Conclusion \u0000ESD trainees, who have the number of gastroscopy more than 5 000, the number of colonoscopy more than 3 000, the detect number of early cancer more than 30 in upper digestive tract and 10 in lower digestive tract, and the usage of ME, EMR and ESD before training, can get a better training effect. The study provides a theoretical basis for selecting appropriate ESD trainees. \u0000 \u0000 \u0000Key words: \u0000Animal models; In vitro; Endoscopic submucosal dissection; Operating training; Dissection time","PeriodicalId":10072,"journal":{"name":"Chinese Journal of Digestive Endoscopy","volume":"37 1","pages":"22-27"},"PeriodicalIF":0.0,"publicationDate":"2020-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47211802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
