title: Efficacy of argon plasma coagulation for gastric antral vascular ectasia associated with chronic liver disease.
abstract: Gastric antral vascular ectasia (GAVE) is a rare cause of chronic gastrointestinal bleeding. The aim of this study was to evaluate the relationship between GAVE with cirrhotic patients and liver dysfunction, portal hypertension and the safety and efficacy of argon plasma coagulation (APC) in treating GAVE with cirrhotic patients. Eight cirrhotic patients with the characteristic endoscopic findings of GAVE were registered. In this study, APC was performed for GAVE in all eight patients. The patients-liver function was classified by Child-Pugh classification and classifications were: two class A, five class B and one class C (mean score: 7.8). Five patients had previously received prophylactic endoscopic injection sclerotherapy for esophageal varices and one had esophageal varices. Balloon-occluded retrograde transvenous obliteration (B-RTO) for gastric varices had been performed in other one patient. Portal hypertensive gastropathy (PHG) was recognized in only one case. APC was performed in all eight patients and one to three treatment sessions were needed (mean: 1.8 sessions). No complications were observed in the initial treatment. During follow-up, endoscopies revealed the recurrence of GAVE in two patients requiring further treatment by APC (recurrence rate: 25%). After APC treatment, the recurrence of GAVE was not observed with endoscopy in the other six patients. The results suggest that GAVE is related to severe liver damage and portal hypertension in cirrhotic patients. APC is a safe and effective treatment against GAVE.
