Comparative study of tissue adhesive therapy versus band ligation in control of actively bleeding esophageal varices.

Background and study aims: Bleeding esophageal varices is a common life-threatening emergency that carries a significant morbidity and mortality. Acute variceal bleeding is considered active when spurting and/or oozing varix is seen at the time of endoscopy, or inactive in the presence of large esophageal varices with blood in the stomach with no other bleeding source at the time of endoscopy. Aim: comparing endoscopic variceal ligation (EVL) versus cyanoacrylate injection (CI) in active esophageal variceal bleeding control. Patients and methods: a retrospective single tertiary center study from April 2014 to February 2018, including 401 patients with active esophageal variceal bleeding. Results: Endoscopic hemostasis was achieved by both endoscopic variceal ligation in 182 patients (91.9%) and cyanoacrylate injection in 197 patients (97.05%) without significant difference (P value 0. 15). Re-bleeding occurred more frequently in EVL group 20 patients (10.1%) compared to 14 patients (6.9%) in CI (P value 0.01). Early six-week Mortality was higher among EVL group (20.7%) compared to CI (17.2%) without statistical significance (P value 0.3). Conclusion: Both EVL and CI are almost as effective in achieving endoscopic hemostasis. CI is more effective, feasible, and could be used as a salvage therapy and/or spared for risky active bleeding esophageal varices.
