Randomized controlled trial of scleroligation versus band ligation alone for eradication of gastroesophageal varices

Abstract

Background and aims: Gastric varices develop in 5% to 33% of patients with portal hypertension. Their most common form is concomitant gastroesophageal varices. Scleroligation (combined sclerotherapy and band ligation) has been used successfully in management of esophageal varices but has not been evaluated previously in the management of gastroesophageal varices. The aim of this work was evaluation of a new scleroligation technique for management of bleeding gastroesophageal varices regarding efficacy, adverse events, variceal recurrence, and survival.

Methods: This study was conducted on 120 cirrhotic patients with bleeding gastroesophageal varices, whom we divided randomly into 2 groups of 60 patients each-a band ligation group and a scleroligation group.

Results: The mean number of sessions was lower in the scleroligation group than in the band ligation group (2.22 ± 0.92 and 3.43 ± 0.67, respectively) (P < .001), as were the duration of treatment and total number of bands used. Cost and survival were comparable in the 2 groups. There was no significant difference between the 2 maneuvers regarding adverse events, recurrence rates, or rebleeding rates after obliteration. Recurrence was significantly higher in patients with larger varices, ulceration, and postprocedure pyrexia. Rebleeding was significantly higher among those who experienced postprocedure pyrexia and developed or had worsening of gastric antral vascular ectasia.

Conclusions: Scleroligation appears to achieve a faster rate of eradication with fewer treatment sessions and total number of bands deployed to achieve variceal obliteration than band ligation and is comparable in cost and in adverse event and recurrence rates.
