The learning curve for using the ENDOCUFF™ was studied by comparing adenoma detection rate (ADR) over a 3-week period. ADR was calculated for each week and weeks 2 and 3 were compared to week 1, which served as the control. The total number of ENDOCUFF™ procedures in week 1 was divided by the number of operators to determine the average procedures needed to overcome the learning curve. 58 patients underwent ENDOCUFF™ assisted colonoscopy during the 3-week period. A total of 15, 21, and 22 patients had procedure performed in weeks 1, 2, and 3, respectively. ADR for week 1 was 20% which increased to 54.5% in week 2 (p=0.03) and reached its peak at 63.6% in week 3 (p=0.004). Given the significant improvement in week 2 compared to week 1, the learning curve was approximately 4 procedures based on a total of 15 procedures performed in week 1 divided amongst four operators.
Conclusion: The results show that that ADR significantly increases with operator experience after four procedures suggesting that it will increase ADR with a short learning curve.
