BACKGROUND: The role of endoscopy in the ligation of gastric varices (GV) remains controversial. This study aimed to evaluate the efficacy of endoscopic band ligation (EBL) using large-volume ligators for the management of non-bleeding GV in patients with cirrhosis.
METHODS: One hundred fifty-eight patients with non-bleeding GV due to cirrhosis were divided randomly into 2 groups: the EBL group and the endoscopic variceal obturation (EVO) group. The EBL group underwent EBL with large-volume ligators and the EVO group underwent tissue glue injection for the treatment of GV. Follow-up endoscopy was performed 3 to 4 weeks after endoscopic treatment. Patients were followed up for ≥6 months after treatment. Eradication, complication, and recurrence rates were evaluated and compared between groups.
RESULTS: The type and size of GV were similar in both groups. No significant difference was found in the mean number of treatment sessions or eradication and recurrence rates after 6 months. Ulcer bleeding occurred in 2 EBL patients (2.50%) after ligation, whereas 8 EVO patients (10.25%) experienced bleeding due to glue extrusion. The bleeding rate after endoscopic treatment significantly differed between the groups. In the EVO group, 1 patient developed renal embolism after injection and 2 patients developed sepsis. The prevalence of postoperative fever was significantly higher in the EVO group than in the EBL group.
CONCLUSION SUBSECTIONS: Large-volume band ligators have similar efficacy to tissue glue for eradicating GV, however, the former is safer. Nevertheless, multicenter studies are needed to further confirm these results.
