Efficacy and Safety of EUS-Guided Therapy Versus BRTO for Gastric Varices With Shunt

Plain-language summary

This study is a retrospective, multi-center and observational clinical study. Renmin Hospital of Wuhan University, Beijing Friendship Hospital, Capital Medical University, The fifth medical center of PLA General Hospital, Zhongshan Hospital, Fudan University, Shanghai, Nanjing Drum Tower Hospital affiliated Nanjing University Medical School and Xiangyang Central Hospital will participate in the study. Investigators would like to provide evidence-based medical evidence by evaluating and comparing the efficacy and safety of endoscopic ultrasound (EUS)-guided coil embolization combined with endoscopic cyanoacrylate injection and balloon-occluded retrograde transvenous obliteration (BRTO) in the treatment of gastric varices (GV) with spontaneous portosystemic shunt (SPSS). Between January 2014 and December 2020, patients with GV secondary to portal hypertension admitted to a tertiary medical center, are enrolled consecutively according to the following criteria: (1) age≥18 years; (2)endoscopic examination confirms the presence of GV; (3) CTA of the portal system and EUS revealed the presence of SPSS, the diameter was between 5 mm to 15 mm; (4) treatment with EUS-guided coil combined with endoscopic cyanoacrylate injection or BRTO. Exclusion criteria are as follows: (1)malignant tumors; (2) hepatic encephalopathy, hepatorenal syndrome or multiple organ failure; (3) previously received esophagus or stomach surgery; (4) pregnant. Investigators will collect patients' data of baseline character, treatment, postoperative and follow-up. All patients will be followed up until the progress of the disease or the end of the study. And rebleeding, ectopic embolism, survival, and sequential treatment will be recorded during the follow-up period. The primary endpoint are five-day rebleeding rate and six-week mortality rate. The secondary endpoint are: technical success rate, incidence of ectopic embolism, eradication of GV, one-year rebleeding rate, one-year mortality rate, and cost-effectiveness ratio. All data and information use SPSS statistical software to complete all statistical analysis.
