Effect of the manipulation of the duodenal papilla during double balloon enteroscopy

Table 3 Comparison of histopathological features (mean ± SD) between the GP, GP + DBE groups according to the categorization scale given in Table 1

Group	Edema	Vacuolization	Necrosis	Vessels congestion	Inflammation
GP	3.38 ± 0.66	2.95 ± 0.831	1.59 ± 0.751	0.89 ± 0.44	0.21 ± 0.51
GP + DBE	3.29 ± 0.64	2.56 ± 0.97	1.32 ± 0.75	0.93 ± 0.41	0.21 ± 0.56

¹The existence of significant differences at 95% significance level. Control group is not included, as it had no lesions. Group DBE (GDBE) is also not included because the histological assessment was performed at 7 d after procedure[19]. GP: Group papilla; DBE: Double balloon enteroscopy.
