| Abstract: | Abstract: The hemostatic effects of hemoclipping, the pure ethanol local injection method and the heat probe methods on hemorrhagic gastric ulcers associated with exposed blood vessels, were compared. The locations of the ulcers and exposed blood vessles, as well as characteristics and the severity of the hemorrhage were discussed. The hemoclipping method was used on 59 patients, the pure ethanol local injection on 32 patients, and the heat probe methods on 26 patients. The hemoclipping and pure ethanol local injection methods were effective in all of the patients in whom the exposed blood vessels were present around the margin of ulcers. The efficacy rate was 91%, 92% and 92%, respectively, when exposed blood vessels were found at the base of the ulcer. The efficacy rate was 94%, 100% and 80% for the three hemostatic methods, respectively, when an oozing hemorrhage was present. The three methods had an efficacy rate of 100% when only blood clots were present. The efficacy rate for a spurting hemorrhage was 86%, 71% and 67%, respectively, for the three methods. The hemoclipping and pure ethanol local injection were effective in 100% of slight and moderate hemorrhage cases, while the heat probe method was effective in only 89% of moderate cases. The efficacy rate was 85%, 85% and 83%, respectively, for severe cases. Overall, the efficacy rate was 93% for the hemoclipping method, 94% for the pure ethanol local injection and 92% for the heat probe method, and there was no significant difference between the three methods with regard to the overall efficacy rate. |
