Gastric Antral Vascular Ectasia in Systemic Sclerosis: Current Concepts

الملخص EN

Introduction.

Gastric antral vascular ectasia (GAVE) is a rare entity with unique endoscopic appearance described as “watermelon stomach.” It has been associated with systemic sclerosis but the pathophysiological changes leading to GAVE have not been explained and still remain uncertain.

Methods.

Databases Medline, Scopus, Embase, PubMed, and Cochrane were searched for relevant papers.

The main search words were “Gastric antral vascular ectasia,” “Watermelon Stomach,” “GAVE,” “Scleroderma,” and “Systemic Sclerosis.” Fifty-four papers were considered for this review.

Results.

GAVE is a rare entity in the spectrum of manifestations of systemic sclerosis with unknown pathogenesis.

Most patients with systemic sclerosis and GAVE present with asymptomatic anemia, iron deficiency anemia, or heavy acute gastrointestinal bleeding.

Symptomatic therapy and endoscopic ablation are the first-line of treatment.

Surgical approach may be recommended for patients who do not respond to medical or endoscopic therapies.

Conclusion.

GAVE can be properly diagnosed and treated.

Early diagnosis is key in the management of GAVE because it makes symptomatic therapies and endoscopic approaches feasible.

A high index of suspicion is critical.

Future studies and a critical review of the current findings about GAVE are needed to understand the role of this condition in systemic sclerosis.
