The authors developed a new method of endoscopic varix ligation (EVL) using a detachable snare and a transparent cap with rim (EVLsc). The advantages of EVLsc are as follows; 1) no need for an overtube, 2) multiple varix ligation can be achieved in a relatively short time after an easy preparation, and 3) the procedure is associated with less discomfort for the patient. Between August 1995 and December 1996, 31 patients with esophageal varices were treated in Sakura National Hospital by EVL, and were randomized into two groups; 16 with EVLsc and 15 with conventional EVL. Each patient was treated only by the randomly chosen method for the purpose of achieving complete hemostasis and/ or eradicating esophageal varices at risk for bleeding. The only major complication was pharyngeal injury due to overtube insertion in the EVL group. There were no complications in the EVLsc group. Eradication was achieved in 14 of 16 cases (87.5%) in the EVLsc group, and 13 of 15 (86.7%) in the EVL group, there being no statistically significant difference between the two groups. The EVLsc was not associated with discomfort, required no complex techniques, and satisfactory results were obtained.
