Bamboo joint-like appearance of the stomach: a histopathological study

A bamboo joint‐like (BJL) appearance is an endoscopic finding characterized by swollen longitudinal folds transversed by erosive fissures or linear furrows, and it seems to be associated with Crohn's disease (CD). We performed gastroduodenoscopy in 1781 patients, and found BJL lesions in 15 (65...

Description
Summary:A bamboo joint‐like (BJL) appearance is an endoscopic finding characterized by swollen longitudinal folds transversed by erosive fissures or linear furrows, and it seems to be associated with Crohn's disease (CD). We performed gastroduodenoscopy in 1781 patients, and found BJL lesions in 15 (65.2%) of 23 CD patients and 20 (1.1%) of 1758 non‐CD patients. Histological examination of the biopsy specimens showed sharp, fissure‐like erosion or mucosal cleft in 7 (50%) out of 14 CD patients and one (20%) out of 5 non‐CD patients. All cases with fissure‐like erosion or, mucosal cleft revealed lymphoid aggregates, eosinophilic infiltration and edema in the superficial portion of the surrounding lamina propria. Epithelioid granuloma was seen at the base of the fissure‐like erosion in two cases with CD. Our results indicated that fissure‐like erosion or mucosal cleft in gastric biopsy specimens reflects the BJL appearance, and that such findings may provide a diagnostic clue to CD.
