Training of surgical endoscopists in Korea: assessment of the learning curve using a cumulative sum model.
OBJECTIVE
Surgeons' interest and participation in endoscopy have increased recently. The aims of the present study were to assess the learning curve for surgical training in upper endoscopy and to suggest an appropriate training program for surgeons in Korea.


METHODS
Under the supervision of skilled endoscopists, 4 trainees who participated in this study performed more than 150 esophagogastroduodenoscopy procedures, according to the recommendations of the American Society for Gastrointestinal Endoscopy. The success of the procedures was defined as the fulfillment of designated time and checkpoints. A cumulative sum model was used to assess the learning curve.


RESULTS
During the same period, the 4 trainees completed 158, 160, 166, and 180 procedures, respectively. Plateau points occurred on the learning curve at the 81st, 90th, 98th, and 111th case in the cumulative sum model and the mean value of the plateau was the 95th case.


CONCLUSIONS
An intensive education tool and training module that meets the conditions of surgical residents is mandatory for the training of proficient surgical endoscopists.
