The endoscopic hemostasis method using paired bipolar electrocoagulator (BPEC) that we developed for control of upper gastrointestinal bleeding is reported and the results discussed. A total of 264 patients were treated with BPEC on 316 occasions between September 1980 and August 1992. Subjects consisted of 57 females and 207 males. Arrest of bleeding was achieved by BPEC in 307 of 316 occasions (97.2%). No complications related to the procedure were noted during the observation period. The effects of four types of electrodes, 3 bipolar electrocoagulators and 1 heater probe, were compared by in vitro experiment. The degenerative width and depth was compared on fresh human stomachs that had been resected due to perforated duodenal ulcer. It was confirmed that the mean width of the coagulated area produced by BPEC was significantly (P<0.001) smaller than that of the other three probes, and BPEC produced the deepest, yet safe degenerative depth among the four methods. We conclude that BPEC is highly effective in hemostasis and superior to various other hemostatic methods in its operability, safety, portability and equal to other methods in cost.
