Abstract
We have experienced the recurrent esophageal varices of superficial F0-F1 type after endoscoprc treatment. These recurrent varices have been treated by endoscoprc injection sclerotherapy(EIS)with 1%Aethoxysklerol(1%AS). We performed endoscopic variceal electrocoagulation (EVE)for the eradication of recurrent esophageal varices of superficial F0-F1 type, We discussed the therapeutic effect and usefulness of EVE compared with EIS with 1%AS. We tried to perform EVE in 8 patients with the recurrent esophageal varices of superficial F0-F1 type. Electrocoagulation was conducted with an output 30-35 Watt using the monopolar device. The 8 patients were treated 20 times using 5 sec of individual electrocoagulation. We achieved the eradication in 5(62.5%)and the slight residual in 3 (37.5%)out of 8 patients 6 months after EVE. We recognized pyrexia in 2(25.0%)and dysphagia in 1(12.5%)with the complications of patients treated by EKE. As control, we performed EIS with 1%AS in 8 patients, and achieved the eradication in 3(37.5%), the slight residual in 4(50.0%)and the mild residual in 1(12.5%)out of 8 patients 6 months after EIS with 1%AS. We recognized pyrexia in 2(25.0%), dysphagia in 3(37, 5%)and retrosternal pain in 2(25.0%)with the complications of patients treated by EIS with 1% AS. The electrocoagulation unit has been spreaded in the many hospitals. The technique of electrocoagulation has been common for endoscopic treatments and is often used for hemostasis and polypectomy. EVE is the reasonable technique using thermal therapy that we can burn directly and disappear the superficial esophageal varices. We considered that EVE was easier to manipulate than EIS with 1%AS and could cause shallow and uniform ulcerations without esophageal stenosis. EVE was achieved the better therapeutic effect and less invasion compared with EMS with 1%AS. In conclusion, EVE is the reasonable and useful therapy for the recurrent esophageal varices of superficial F0-F1 type.
