Abstract:
Objective:To investigate the learning curves of gastroscopy and colonoscopy for surgeons.Methods:Clinical data of ordinary digestive endoscopy performed by gastrointestinal surgeons in Peking University People's Hospital from March, 2022 to March, 2024 were collected retrospectively. Learning curves were plotted according to the number of examinations and learning time, and the cumulative sum control chart method was used to determine the number of cases required to achieve proficiency in endoscopic examination.Results:Six gastrointestinal surgeons (sequentially) received training in gastroscopy and colonoscopy. All surgeons were male physicians with a doctoral degree and the professional title of attending physician. The average age was (33.0 ±1.9) years, and the average job tenure was (4.0±1.8) years. The median time required for proficiency in gastroscopy was 31 weeks, with a median number of cases of 624. Similarly, the median time required for proficiency in colonoscopy was also 31 weeks but with a median number of cases of 470.Conclusions:Surgeons need at least 31 weeks of independent operation to become proficient in endoscopic examination and more than 600 cases to be proficient in gastroscopy. Surgeons with gastroscopy experience also need 31 weeks of independent operation but at least 450 cases to become proficient in colonoscopy.
