BACKGROUND In nonvariceal upper gastrointestinal bleeding(NVUGIB),the optimal volume of adrenaline,the optimal number of hemoclips,and the application of thermal coagulation in determining patient outcomes have not been well studied.AIM To demonstrate a dose-response relationship between the commonly used endoscopic modalities for the treatment of non-variceal upper gastrointestinal bleeding and various clinical outcomes.METHODS Patients presenting with NVUGIB were retrospectively identified and analyzed.These patients were stratified as follows:(1)>10 mL of adrenaline injected vs≤10 mL;(2)>1 hemoclip placed vs≤1 hemoclip;(3)Heater probe used or not;and(4)>2 treatment modalities used vs≤2.The primary outcomes were rebleeding and the need for repeat endoscopy.The secondary outcomes were the need for surgery,required transfusions,length of hospital stay,death during the same admission period and 30 d mortality.Patients with NVUGIB who required endoscopic therapy were included.Those who did not require endoscopic therapy or were initially treated with surgery or embolization were excluded.RESULTS In all,501 patients with NVUGIB were treated.One hundred sixty-one(32.1%)patients needed endoscopic therapy.The injection of<10 mL of adrenaline was associated with less rebleeding(P<0.0001),the need for repeat endoscopy(P=0.001)and a decreased length of hospital stay(P=0.026).The use of>2 treatment modalities were associated with increased rebleeding(P=0.009)and the need for repeat endoscopy(P=0.048).The placement of>1 hemoclip was associated with a decreased length of hospital stay(P=0.044).The rates of surgery and death were low,and there were no other significant differences between the patient groups.CONCLUSION The more restrictive use of adrenaline and number of endoscopic modalities to treat NVUGIB with the more liberal use of hemoclips was associated with better patient outcomes.
