Background
/Aims: Radiofrequency ablation (RFA) is the first-line therapy for dysplastic Barrett’s esophagus (BE). Therefore, cryotherapy has emerged as an alternative treatment option. This study aimed to compare the efficacies of these two techniques based on the rates of complete eradication of intestinal metaplasia (CE-IM) and dysplasia (CE-D). Adverse events and recurrence have also been reported.
Methods
An electronic search was conducted using the Medline (PubMed), Embase, LILACS, and Google Scholar databases until December 2022. Studies were included comparing cryotherapy and RFA for treating dysplastic BE with or without early esophageal neoplasia. This study was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
Results
Three retrospective cohort studies involving 627 patients were included. Of these, 399 patients underwent RFA, and 228 were treated with cryotherapy. There was no difference in CE-IM (risk difference [RD], –0.03; 95% confidence interval [CI], –0.25 to 0.19; p=0.78; I2=86%) as well as in CE-D (RD, –0.03; 95% CI, –0.15 to 0.09; p=0.64; I2=70%) between the groups. The absolute number of adverse events was low, and there was no difference in the recurrence rate.
Conclusions
Cryotherapy and RFA were equally effective in treating dysplastic BE, with or without early esophageal neoplasia.

Background
/Aims: Argon plasma coagulation (APC) is the most commonly used endoscopic treatment for gastric antral vascular ectasia (GAVE). Endoscopic band ligation (EBL) has emerged as an alternative therapy. Our goal was to evaluate the feasibility, efficacy, and safety of APC and EBL for the treatment of GAVE. This is the first systematic review that included only randomized controlled trials (RCTs) on this topic.
Methods
A comprehensive search was performed using electronic databases to identify RCTs comparing APC and EBL for the treatment of GAVE following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines.
Results
Four RCTs were included, with a total of 204 patients. EBL was related to higher endoscopic eradication rates risk difference [RD], 0.29; 95% confidence interval [CI] [0.14, 0.44]; I2=0%) and less bleeding recurrence than APC (RD, 0.29; 95% CI [0.15, 0.44]; I2=0%). Patients treated with EBL required fewer blood transfusions (mean difference [MD], 1.49; 95% CI [0.28, 2.71]; I2=96%) and hospitalizations (MD, 0.29; 95% CI [0.19, 0.39]; I2=0%). The number of sessions required for the obliteration of lesions was higher with APC. There was no difference in the incidence of adverse events.
Conclusions
EBL is superior to APC in the treatment of GAVE in terms of endoscopic eradication rates, recurrence of bleeding, and transfusion requirements.
