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

Figure 1 Between groups comparison of serum levels of amylase (A), lipase (B) and CRP (C) at different sampling times (Basal, End of endoscopy and 24 h later, mean ± SD). ^a,bDifferent superscripts over the bars within the same time interval indicate significant differences between GP, GP + DBE, GDBE and GC at 95% confidence (P < 0.05). GP: Group papilla; DBE: Double balloon enteroscopy; GC: Group control; GDBE: Group DBE.

Figure 2 Photomicrographs of the left lobe (tail) of porcine pancreas group Group Papilla. A: Pancreas showing focal necrosis perivascular with evidence of vacuolization in acinar cells; B: Magnification of previous image, view of acinar cell´s cytoplasm vacuolated. The nuclei are fragmented and shrunken. Hematoxylin and eosin staining.

Figure 3 Photomicrographs of the left lobe (tail) of porcine pancreas of group GP + DBE. A: Pancreas with different degree of perivascular necrosis and low level of vacuolization; B: Pancreas with perivascular coagulative necrosis. Hematoxylin and eosin staining. GP: Group papilla; DBE: Double balloon enteroscopy.
