BACKGROUND The high rebleeding rate and severe adverse events have raised concerns regarding the safety of endoscopic cyanoacrylate as a conventional treatment for gastric variceal hemorrhage.Clip-assisted endoscopic cyanoacrylate injection(Clip-CYA)and endoscopic ultrasound-guided coil and cyanoacrylate injection(EUS-CG)are two currently used modalities.There are limited data comparing the two techniques.AIM To compare the efficacy,safety,and procedural characteristics of Clip-CYA vs EUS-CG for treatment of gastric varices(GVs)with spontaneous portosystemic shunts.METHODS Between April 2019 and August 2023,162 patients with GVs and concomitant gastrorenal or splenorenal shunts who underwent either Clip-CYA or EUS-CG at our center were included.After 1:2 propensity score matching,108 patients were included in the final analysis.The evaluated outcomes included the amount of cyanoacrylate,eradication of GVs,cyanoacrylate embolization,all-cause rebleeding,operating time and endoscopic therapy costs.RESULTS Of the 108 patients,72(male,83.3%;mean age,56.2±10.8 years)received Clip-CYA,and 36(male,72.2%;mean age,59.1±10.7 years)received EUS-CG.The amount of cyanoacrylate used,rates of obliteration of GVs and all-cause rebleeding were similar between the two groups(2.0±1.1 mL vs 2.0±0.6 mL,P=0.913;91.7%vs 94.4%,P=0.603;and 23.6%vs 19.4%,P=0.623,respectively).No cyanoacrylate embolization occurred in either group.Compared with EUS-CG,Clip-CYA was associated with significantly shorter operating times(24.0±9.9 minutes vs 47.1±21.0 minutes,P<0.001)and lower endoscopic therapy costs(7523.4±5719.4 Chinese yuan vs 11153.7±7679.1 Chinese yuan,P=0.007).These advantages persisted in the subgroup analysis of patients whose GVs had a maximum diameter>3 cm or>4 cm.CONCLUSION Compared with EUS-CG,Clip-CYA of GVs appears to be a safe procedure with shorter operating times and lower endoscopic therapy costs.
