Learning curve for double-balloon enteroscopy: Findings from an analysis of 282 procedures

Table 3 Analysis of 98 cases of retrograde double-balloon enteroscopy with regard to technical success rate (divided into 3 blocks of 33, 33, 32 cases)

Block No.	Cases classified as technical success (finding the target lesion and/or stable overtube intubation in ileum)	Success rate (%)	P1
1 (n = 33)	23/33	70.0	0.09
2 (n = 33)	26/33	78.8
3 (n = 32)	28/32	87.5

¹Logistic regression analysis testing for trend over time. Overall success rate: 77/98 = 78.6%.
