Background Patients who have bleeding from esophageal varicesare at high risk for rebleeding and death. We compared the efficacyand safety of endoscopic sclerotherapy with the efficacy andsafety of nadolol plus isosorbide mononitrate for the preventionof variceal rebleeding.
Methods Eighty-six hospitalized patients with cirrhosis andbleeding from esophageal varices diagnosed by endoscopy wererandomly assigned to treatment with repeated sclerotherapy (43patients) or nadolol plus isosorbide-5-mononitrate (43 patients).The primary outcomes were rebleeding, death, and complications.The hepatic venous pressure gradient was measured at base lineand after three months.
Results Base-line data were similar in the two groups, and themedian follow-up was 18 months in both. Eleven patients in themedication group and 23 in the sclerotherapy group had rebleeding.The actuarial probability of remaining free of rebleeding washigher in the medication group for all episodes related to portalhypertension (P = 0.001) and variceal rebleeding (P = 0.002).Four patients in the medication group and nine in the sclerotherapygroup died (P = 0.07 for the difference in the actuarial probabilityof survival). Seven patients in the medication group and 16in the sclerotherapy group had treatment-related complications(P = 0.03). Thirty-one patients in the medication group underwenttwo hemodynamic studies; 1 of the 13 patients with more thana 20 percent decrease in the hepatic venous pressure gradienthad rebleeding, as compared with 8 of the 18 with smaller decreasesin the pressure gradient (P = 0.04 for the actuarial probabilityof rebleeding at two years).
Conclusions As compared with sclerotherapy, nadolol plus isosorbidemononitrate significantly decreased the risk of rebleeding fromesophageal varices.
