Band ligation vs endoscopic sclerotherapy in esophageal varices: a prospective randomized comparison

A prospective randomized trial was conducted to compare efficacy, safety and complications of band ligation (BL) with sclerotherapy (Scl). Patients with esophageal variceal bleeding were randomized into two study groups. BL (group A) was done in 28 patients whereas 30 patients (group B) had Scl. After initial treatment, follow-up sessions were repeated by the same method every two weeks till obliteration or reduction to grade 1. Subsequent sessions of endoscopy were done every three months, same procedure was repeated for recurrence of varices and for any episode of rebleeding. Initial control of bleeding by Scl was achieved in 22 of 28 patients (78%) and in 23 of 24 patients (96%) with BL. Eradication of varices was significantly better achieved in BL group, with less treatment sessions required in Group A as compared with group B 2 +/- 1.2 vs 5 +/- 2.5, P < 0.001). Major complications (3% vs 16%, P < 0.05) as well as mortality (11% vs 21%, P > 0.05) was higher in group B. Band ligation was more effective mode of treatment and was associated with lesser early mortality and complications as compared with sclerotherapy.
