Abstract
BACKGROUND/AIMS: Endoscopic variceal ligation is superior to sclerotherapy because of its lower rebleeding and complication rates. However, ligation is not without drawbacks due to a higher tendency to variceal recurrence. We conducted a randomized cohort study to delineate the long-term history of variceal recurrence following ligation and sclerotherapy, and to clarify the impact of recurrence on rebleeding and on the consumption of endoscopic treatment resources. METHODS:Two hundred cirrhotic patients with esophageal variceal bleeding were randomized to undergo maintenance endoscopic variceal sclerotherapy or ligation. RESULTS: One hundred and forty-one patients achieved variceal eradication and were regularly followed up for 2.2 to 6.7 (mean: 5.1 +/- 1.2) years. The demographic data, hepatic reserve, bleeding severity, and endoscopic features of both sclerotherapy (n=70) and ligation (n=71) showed no difference. Forty (57.1%) patients who underwent sclerotherapy experienced 58 recurrences of esophageal varices, in contrast to the 46 (64.8%) patients who underwent ligation and experienced 81 episodes of recurrence. Kaplan-Meier analysis showed that within 2 years variceal recurrence was more frequent for ligation than sclerotherapy, and the difference decreased thereafter. Multiple recurrence appeared more common with ligation (1/2/3/4/5 episodes of recurrence: 46/23/8/3/1 vs. 40/14/3/1/0, p=0.08). On multifactorial analysis, the endoscopic treatment method and red wale markings were the two factors determining variceal recurrence. Rebleeding from recurrent esophageal varices was unusual and showed no difference between the two groups (7/58 vs. 6/81, p>0.05). Rebleeding from gastric varices was more common after eradication by sclerotherapy (7/19 vs. 1/16, p=0.085) than by ligation. The number of sessions required for eradication of recurrent varices was no different between the two groups. CONCLUSIONS:Early recurrence and multiple recurrence of esophageal varices are more likely in patients undergoingendoscopic ligation, compared to sclerotherapy; however, the recurrence did not lead to a higher risk of rebleeding or require more endoscopic treatment.
