A 32-year-old man, complaining of epigastralgia and peri-navel pain, took an endoscopic examination in August, 1989. A curious lesion was observed on the lesser curvature from the cardia to the middle gastric body. This lesion consisted of three enlarged folds transversed by fissuring erosions in a longitudinal alignment, but lacking a longitudinal ulcer. Biopsy from a fissuring erosion disclosed microgranulomas indicating Crohn's disease. Definite diagnosis of Crohn's disease ileitis type was obtained with x-ray examination of the small intestine, showing longitudinal ulcers, cobblestone appearance and intestinal strictures as skip lesions. Since then, we have paid attention to the lesser curvature of the gastric body and cardia in the endoscopic observation of Crohn's disease patients. Similar lesions were found in 13 patients (52%) out of 25 cases of Crohn's disease. Although enlargement of folds was less prominent, these lesions showed the same location, morphology and histopathology in biopsy as the lesion of the case presented. We named this endoscopic sign "bamboo joint-like erosions".Microgranulomas were detected in 8 cases (64%) out of 13 patients with bamboo joint-like erosions, by examining 50 serial sections of biopsy specimens. We propose the bamboo joint-like erosions of the gastric body as a novel endoscopic sign of Crohn's disease.
