title: Variceal rebleeding: use of drug therapy and endoscopic band ligation.
abstract: Patients surviving a variceal bleed are at high risk of re-bleeding with a mortality of 25-50% during a 1-2 year follow-up. Several studies and meta-analyses have demonstrated reduced rates of oesophageal variceal rebleeding with the use of β-blockers. However, their use can be limited by contraindications or intolerance to therapy. Other trials have shown that addition of nitrates may improve the efficacy of β-blockers in prevention of variceal re-bleeding. Endoscopic variceal band ligation (VBL) has been shown in meta-analyses to decrease the rates of rebleeding and mortality compared with endoscopic sclerotherapy. Studies comparing combined drug therapy with VBL have shown similar rebleeding rates although there is a suggestion that survival may be higher in those given drug therapy. Recent data suggest that combined VBL and drug therapy reduces the risk of rebleeding from oesophageal varices compared with either therapy alone; however there appears to be no reduction in overall mortality.
