We report a rare case of a small-bowel lymphangioma causing massive gastrointestinal (GI) bleeding that we successfully diagnosed and treated using double-balloon enteroscopy (DBE). An 81-year-old woman suffering from repeated GI bleeding of unknown origin underwent a capsule endoscopy at a previous hospital. She was suspected of having bleeding from the jejunum, and was referred to our department for diagnosis and treatment. An oral DBE revealed a 20 mm × 10 mm, regularly surfaced, white to yellowish, elongated, pedunculated jejunal polyp with small erosions at 10 cm distal to the ligament of Treiz. Since no other source of bleeding was identified by endoscopy in the deep jejunum, anendoscopic polypectomy (EP) was performed for this lesion. A subsequent histopathological examination of the resected polyp showed clusters of lymphatic vessels with marked cystic dilatation in the submucosa and the deep layer of the lamina propria mucosae. These characteristics are consistent with the typical features of small-bowel lymphangioma with erosions. Although clip-ping hemostasis was performed during EP, re-bleeding occurred. Finally, a complete hemostasis was achieved by performing an additional argon plasma coagulation.
