The treatment of oesophageal varices: a debate and a discussion.

Abstract

At the Biennial Meeting of the International Association for the Study of the Liver, in Cape Town, South Africa, 20-24 February 1996, the treatment of oesophageal varices was selected as a subject for the discussion of controversies in portal hypertension. This review gives a summary of that discussion. Dr Didier LeBrec gave a broad overview of the medical management of oesophageal varices by presenting a list of 52 pharmacological agents that reduce portal venous pressure and presented the advantages and disadvantages of each. He emphasized that recent randomized clinical trials (RCT) have demonstrated that propranolol delays and decreases the occurrence of haemorrhage from varices in patients who have not previously suffered such complications. He also reported that isosorbidemononitrate is equally effective and further enhances the effect of propranolol. He also reported that the effects of propranolol plus endoscopic sclerotherapy (EST) were more effective than EST alone in preventing haemorrhage, but not in improving survival. Finally he noted that propranolol in high dosage did not prevent the development of large varices in cirrhotic patients with small or undetectable varices. Dr John Terblanche compared the efficacy of EST and endoscopic ligation of varices (ELV) and reported that all four RCTs found ELV to be superior. He discussed portacaval anastomosis (PCA) and concluded that only emergency PCA as reported by Orloff, is thought to be truly beneficial, and suggested that EST, plus ELV may be the treatment of choice. Dr Harold O. Conn, who served as the moderator of this session summarized the presentations and pointed out that liver transplantation is the most effective form of therapy of all, albeit extremely complex and expensive. He discussed transjugular intrahepatic portosystemic shunts (TIPS), the newest form of therapy, and emphasized its virtues (immediate reduction of portal venous pressure) and its limitations (frequent portosystemic encephalopathy and frequent spontaneous stenoses). He presented a brief discussion of the prevention of the development of the varices themselves, currently termed "pre-primary prophylaxis', a hope for the future. He ended with "Predictions' which if proven correct will give a preview of portal hypertension in the 21st century.
