Utility of single and double balloon endoscopy in patients with difficult colonoscopy: A randomized controlled trial

Table 2 Cecal intubation rate and endoscopy-related outcomes of balloon colonoscopy

	SBC group (n = 11)	DBC group (n = 10)	P value
Successful cecal intubation, n (%)	10 (91)	10 (100)	0.991
Cecal intubation time3 (min) [median (range)]	18.0 (10-85)	12.8 (9.5-42)	0.172
Total X-ray fluoroscopic time (min) [median (range)]	3 (1-7)	1 (1-5)	0.122
Pain score4 [median (range)]	5 (1-10)	5 (1-6)	0.642

¹Fisher’s exact test;

²Mann-Whitney U-test;

³The cecal intubation time was compared for cases with successful cecal intubation;

⁴After balloon endoscopy, the patients were asked to evaluate the pain during the procedure on a 10-point analog scale (1 = no pain, 10 = worst imaginable pain). SBC: Single-balloon colonoscopy; DBC: Double-balloon colonoscopy.
