Abstract
Background: EUS is an operator-dependent procedure and requires more technical and cognitive skills than a routine endoscopic procedure. The learning curve for the staging of gastric cancer, however, has not been evaluated.Objective: To evaluate the threshold number of EUS examinations for gastric cancer T staging.Design: Retrospective study.Setting: University-affiliated tertiary care hospital in the Republic of Korea.Patients: Four trainees with no previous EUS experience. Intervention: Analyzing performance of EUS trainees in gastric cancer T staging by using cumulative sum (CUSUM) analysis.Main Outcome Measurements: CUSUM plot and a minimal number of procedures for reaching a plateau.Results: A total of 553 initial EUS examinations for treatment-naive gastric cancers, performed by trainees, were enrolled in the study. The final T stage was determined by experts by using EUS in 332 gastric cancer cases, whereas the T stage of the other 221 lesions was determined by trainees by using EUS. The accuracy of EUS examinations performed by trainees and experts was 72.6% and 84.3%, respectively. The number of EUS examinations required to reach the first plateau in each trainee was 20, 41, 60, and 65. Limitations: Retrospective study with a relatively small number of trainees.Conclusion: The CUSUM scores of all of 4 trainees in the study reached a plateau by the 65th examination.
