Background Blue rubber bleb nevus syndrome (BRBNS) is a rare congenital disease characterized by multifocal venous malformations. It remains a considerable challenge in treating the gastrointestinal (GI) venous malformations due to multiple lesions throughout the GI tract, and the likelihood of recurrence. We report a case study of BRBNS in the GI tract, in which GI venous malformations and related GI bleeding were successfully treated with a combination of multiple endoscopic procedures. Case presentation A 17-year-old man was admitted to our hospital for dizziness and hypodynamia. The symptoms persisted for nearly 1 year. The laboratory tests revealed iron-deficiency anemia with abnormally low hemoglobin (Hb), and a strong positive fecal occult blood test. A total of four hemangiomas were detected: one in the stomach, one in the descending colon, and two in the small intestines with a high risk of hemorrhage. Under gastroendoscopy, enteroscopy, and video capsule endoscopy (VCE) throughout the GI tract, the patient underwent surgical treatment. Endoscopic mucosal resection was initially performed in the stomach and colon, and the lesions in the small intestine were resected with laparoscopy auxiliaried by single-balloon enteroscopy (SBE), during which SBE assisted in identifying the lesions. The patient well-tolerated the procedures, and had a favorable prognosis. Conclusion The combination of single-balloon enteroscopy-assisted laparoscopy and endoscopic mucosal resection was effective for the present case, which could be considered for patients with similar clinical conditions.
