Success of endoscopic injection therapy in correlation with maximal one-day transfusion requirement.

Background and Study Aims : The rate of blood transfusion is related to blood flow and the diameter of the bleeding vessel. Therapeutic endoscopy is less effective in larger vessels. To determine the effect of therapeutic endoscopy with pure ethanol injection in massive peptic ulcer bleeding, we conducted a retrospective study using the maximal one-day blood requirement as an indicator of the required blood transfusion. Patients and Methods : The maximal one-day blood requirement was defined as the total amount of blood transfusion needed within a day to keep hemodynamics stable and hemoglobin above 8.0 g% before therapeutic endoscopy. From January 1986 to May 1993, 283 patients with high-risk signs of the stigmata of hemorrhage on endoscopy, who received pure ethanol injection therapy, were included in this study. There were 214 men and 69 women with a mean age of 58.4 years (ranging from 16 to 93 years). One hundred forty-three had gastric ulcers ; 125 had duodenal ulcers ; and 15 had stomal ulcers. Patients whose maximal one-day blood requirement was less than 1000 ml were assigned to Group I. Patients without, and patients with, major organ diseases whose maximal one-day blood requirement was more than 1000 ml were assigned to Group IIa and Group IIb, respectively. Results : In Group I, 87.1% attained permanent hemostasis ; 51.3% in Group IIa ; and 49.4% in Group IIb. Temporary hemostasis and failure rates were 8.9% and 4.8% in Group I ; 14.5% and 33.8% in Group IIa ; and 21.2% and 29.4% in Group IIb. The rate of permanent hemostasis was significantly lower in patients with massive bleeding (p 0.05). Conclusion : The success rate for pure ethanol injection therapy was lower in patients with a large maximal one-day blood transfusion requirement.
