Does sclerotherapy of remnant little oesophageal varices after endoscopic ligation have impact on the reduction of recurrent varices?: Prospective study

Abstract

Introduction. Endoscopic band ligation (EBL) is superior to endoscopic injection sclerotherapy (EIS) of oesophageal varices, however, EBL is associated with a higher rate of variceal recurrences. Objective. To examine whether the reduction of recurrent varices can be achieved by additional sclerotherapy of remnant little varices after ligation. Methods. Forty-eight patients with liver cirrhosis who had previously bled from oesophageal varices were examined. Endoscopic therapy was performed in order to prevent recurrent variceal bleeding. I group: in 23 patients ligation of oesophageal varices with multi band ligation device was applied (EBL group). II group: in 25 patients sclerotherapy using polydocanol or absolute alcohol was applied after reducing the size of varices using ligation (EBL and EIS group). Results. There was no statistically significant difference between the examined groups of patients in relation to the number of sessions for variceal eradication, recurrence of variceal bleeding, deterioration of portal gastropathy and mortality in the observed period from 18.8?18.6 months (EBL group) and 22.2?26.2 months (EBL and EIS group). Variceal recurrence was verified in 21.7% of patients of the EBL group and 16% of the EBL and EIS group, but the difference was not statistically important. Several complications, such as dysphagia and chest pain, were statistically more frequent in the EBL and EIS group of patients. Conclusion. The combined method of ligation and extra sclerosing of remnant small oesophageal varices after ligation does not have advantage in relation to the ligation alone.
