Failure Factors to Reach the Blind End Using a Short-Type Single-Balloon Enteroscope for ERCP with Roux-en-Y Reconstruction: A Multicenter Retrospective Study

Table 4

Comparison of the rate of reaching the blind end: sSBE vs. sSBE+lSBE.

	sSBE	sSBE+lSBE	value
R-Y with gastrectomy	88% (107/122)	90% (110/122)	0.342
R-Y without gastrectomy	60% (21/35)	91% (32/35)	0.002

R-Y: Roux-en-Y; SBE: single-balloon enteroscope; lSBE: long-type SBE; sSBE: short-type SBE.
