Endoscopic treatment of blue rubber bleb nevus syndrome in a 4-year-old girl with long-term follow-up: A case report.

BACKGROUND

Blue rubber bleb nevus syndrome (BRBNS) is a rare vascular disease, difficult to diagnose and choose a treatment method, especially in young children. There are several limiting factors to the use of enteroscopy for diagnostics and treatment in pediatric patients, in general. The literature on BRBNS cases is limited and presents various therapeutic approaches.

CASE SUMMARY

We present here a case of BRBNS involving a 4-year-old female, whose intestinal venous lesions were successfully treated by endoscopic sclerotherapy and aethoxysklerol foam. Skin lesions, typical for BRBNS, appeared on the 8 d of the child's life and their number increased over the next several months. The child also experienced episodes of critical decrease in hemoglobin level (by as much as 52 g/L) for several years, requiring iron supplementation and several blood transfusions. Video capsule endoscopy revealed numerous vascular formations in the small bowel. The combined findings of gastrointestinal venous formations and skin lesions prompted BRBNS diagnosis. Single-balloon enteroscopy was used to perform sclerotherapy, with aethoxysklerol foam. A positive effect was observed within 19 mo of follow-up. We continue to monitor the patient's hemoglobin level, every 2 wk, and it has remained satisfactory (> 120 g/L).

CONCLUSION

Endoscopic sclerotherapy can be effective in the clinical management of gastrointestinal manifestations of BRBNS in young children.
