简要总结

The EUS-guided combined therapy of coilingand 2-octyl-cyanoacrylate in patients with gastric varices reduced rebleeding and need for reintervention in comparison to EUS-guided coiling alone.The purpose of this study is to determine the efficacy of the primary prophylaxis of GOV II and IGV I with the EUS combined therapy versus beta blocker therapy in patients GOV II and IGV that have never bleed.

详细描述

Gastric variceal bleeding is a severe condition associated with a high mortality. Bleeding from varices bleeding will be defined as the occurrence of hematemesis and/or melena requiring >2 U of blood or a decrease of 2 gm/dl of hemoglobin if no blood transfusion is given, with the confirmed endocopic visualization of GOV II and IGV I.

The beta blocker therapy is an effective method for the prevention of the first esophageal variceal bleeding; however, the efficacy in preventing first gastric variceal bleeding is controversial.

The investigators aimed to compare the efficacy in preventing the first gastric variceal bleeding in patients with documented GOV II and IGV I.

研究组 & 干预措施

EUS-guided combined therapy

Experimental

Patients with endoscopic and EUS documented GOV II and IGV I will be included. Procedure will be performed under general anesthesia using a linear array therapeuthic echoendoscope, coils and cyanoacrylate will be injected within the feeder vessel under EUS and fluroscopic guidance.

干预措施: Coils + Cyanoacrylate Group + beta-blocker (Procedure)

Beta Blocker (Propranolol)

Placebo Comparator

o Beta-blocker (propranolol) will be started at dose of 20 mg twice daily. The principle of incremental dosing was used to achieve the target heart rate for propranolol. The dose will be increased every alternate day to achieve a target heart rate of 55/min or to the maximal dose to 360 mg/day if the medication was well tolerated and the systolic blood pressure was > 90 mm Hg. On the occurrence of intolerable adverse effects, systolic blood pressure < 90 mm Hg or pulse rate < 55/min, the dose of the medication was decreased step-wise, and eventually stopped if these adverse events persisted. Reintroduction of the medication will be attempted if cessation of the medication did not result in improvement of the reported side-effect.

干预措施: beta blocker therapy (Drug)
