Development of a multiple ligator and its endoscopic therapy for patients with esophageal varices / 中国医疗器械杂志

ABSTRACT

The ligators we have developed is a kind of economical and effective six-ring ligator. Endoscopic variceal ligation (EVL) was performed to treat bleeding from esophageal varices in patients with liver cirrhosis using self-made ligator and foreign multiple ligator. There are similar effects with both self-made ligator and foreign mutiple ligator in the control of variceal bleeding, variceal obliteration and rebleeding (93.8%, 87.5%, 0 in the group with self-made ligator, 94.5%, 87.1%, 2.4% in the group with foreign multiple ligator, P>0.05). In terms of the quality index, successful operation rate, hemastatic rate, variceal obliteration rate, rebleeding rate, complications and variceal recurrence rate, the self-made ligator is as good as the foreign multiple ligator, but much cheaper.
