Side effects of varical therapy

One week after endoscopic variceal ligation (EVL). The varices are still strangulated by the elastic O- rings and become necrotic. Some days further on the necrotic tissue has fallen off, leaving behind superficial ulcerations healing quickly thereafter. As a complication of endoscopic variceal sclerotherapy (EVS) a mucosal pouch has developed. Retention of solid food or possible perforation in case of blind endoscopic passage are potential dangers. Retention of tablets can lead to mucosal, erosive lesions.
Stenosis aftzer ligature After numerous ligations of quickly recurring, high grade varices a relative stenosis at the esophago- cardial junction has developped. The esophagus has partly turned into a rigid tube. Presently there are no recurring varices. In case of recurring varices further endoscopic varical ligation is expected to be extremely difficult, since fibrous tissue is specially resistent to suction.
Stenosis after ligature In this case apart from relative stenosis after multiple endoscopic varical ligations for bleeding varices flat ulcerations and inflammatory changes have developped.
