Objective The efficacy of argon plasma coagulation (APC) on gastric antral vascular ectasia (GAVE) may be impaired over time and depends greatly on the application settings. Endoscopic band ligation (EBL) may be an alternative, but study on its efficacy is limited. This study aimed to evaluate and compare the clinical efficacy of APC and EBL in treating GAVE. Methods Changes in the need for blood transfusion, number of treatment sessions and hospitalizations were retrospectively assessed in 63 transfusion‐dependent patients with GAVE (mean age: 67.1 y, 54.0% female) treated with either APC or EBL (45 and 18 patients, respectively) in four tertiary endoscopic centers. Results Both methods substantially increased hemoglobin levels and decreased patients' need for a transfusion (22.0 ± 4.0 g/L and −5.62 ± 2.30 units of packed red blood cells [RBC] with APC, and 27.4 ± 6.1 g/L and −4.79 ± 2.46 units of packed RBC with EBL), without a significant statistical difference between the methods. However, fewer EBL sessions were required both for the cessation of need for a transfusion compared with those for the resolution of GAVE lesions (0.90 ± 0.10 vs 1.69 ± 0.31, P = 0.028). Conclusions Both APC and EBL are effective in GAVE treatment. EBL may be superior in terms of number of treatment sessions, but not in its influence on hemoglobin level and need for transfusion. Further prospective studies with large, homogeneous sample size and standardized APC settings are needed.
