Abstract
Objective
To investigate the prerequisites for endoscopists, who were chosen to receive endoscopic submucosal dissection (ESD) training.
Methods
A total of 41 trainees, who attended ESD training in the endoscopic center of Nanjing Drum Tower Hospital from January 2017 to June 2018 were enrolled in the study. 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.
Results
Among 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.
Conclusion
ESD 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.

期刊介绍:
Chinese Journal of Digestive Endoscopy is a high-level medical academic journal specializing in digestive endoscopy, which was renamed Chinese Journal of Digestive Endoscopy in August 1996 from Endoscopy.
Chinese Journal of Digestive Endoscopy mainly reports the leading scientific research results of esophagoscopy, gastroscopy, duodenoscopy, choledochoscopy, laparoscopy, colorectoscopy, small enteroscopy, sigmoidoscopy, etc. and the progress of their equipments and technologies at home and abroad, as well as the clinical diagnosis and treatment experience.
The main columns are: treatises, abstracts of treatises, clinical reports, technical exchanges, special case reports and endoscopic complications.
The target readers are digestive system diseases and digestive endoscopy workers who are engaged in medical treatment, teaching and scientific research.
Chinese Journal of Digestive Endoscopy has been indexed by ISTIC, PKU, CSAD, WPRIM.
