Abstract:Objective To explore the clinical value of endoscopic intervention in preventing rebleeding of Forrest Ⅱb grade ulcers.Method A retrospective analysis was conducted on the clinical data of 114 patients from January 2015 to April 2023 due to gastrointestinal bleeding, who were confirmed by gastroscopy as Forrest Ⅱb grade ulcers. 86 (75.4%, 86/114) patients received endoscopic treatment as endoscopic treatment group, while 28 patients only received medication treatment as medication treatment group. Compare the effectiveness of endoscopic treatment and different endoscopic hemostatic methods for preventing rebleeding.Results There were no statistically significant differences in age, gender, clinical symptom, systolic pressure, hemoglobin concentration, and ulcer site between endoscopic and medication treatment patients (P > 0.05). In terms of ulcer size, the length of ulcer in the endoscopic treatment group was smaller than that in the medication treatment group [(9.5 ± 5.3) mm vs (12.8 ± 7.7) mm], the difference was statistically significant (P = 0.013). The rebleeding rate of medication treatment group was 21.4% (6/28); Among the endoscopic treatment group, 85 patients (98.8%, 85/86) successfully underwent endoscopic treatment, with a rebleeding rate of 11.8% (10/85), which was lower than that of medication treatment group, but the difference was not statistically significant (P = 0.337). Among the patients who successfully underwent endoscopic treatment, 62 cases were treated with injection of diluted adrenaline alone, 6 cases with titanium clips, and 17 cases were treated with electrocoagulation or electrocoagulation combined with other hemostatic methods. The rebleeding rate were 12.9% (8/62), 16.7% (1/6), and 5.9% (1/17), respectively, which were lower than that of medication treatment patients, but the difference was not statistically significant (P = 0.474). Due to the need for endoscopic treatment, 15 patients were treated with a snare or thermal hemostatic forceps to remove the surface blood clot of the ulcer. Among them, 3 cases had jet bleeding at the base (2 cases were successfully stopped by electrocoagulation; 1 case had a large amount of bleeding, but endoscopic hemostasis failed, and intervention embolization successfully stopped the bleeding). Among of 16 patients with rebleeding, 3 patients were treated with conservative management, and all of them were successfully stopped bleeding; 6 cases underwent endoscopic treatment again, of which 4 cases were successfully hemostasis by endoscopy, and 2 cases were successfully hemostasis by surgery after endoscopic hemostasis failure; interventional embolization in 1 case, and successfully hemostasis; 6 patients underwent direct surgical procedures, all of which successfully stopped bleeding, but one patient developed multiple organ failure during hospitalization and died without bleeding.Conclusion Endoscopic intervention can to some extent reduce the incidence of rebleeding in Forrest Ⅱb grade ulcers. The effect of electrocoagulation hemostasis on preventing rebleeding is better than that of injection dilution adrenaline method. However, there is a risk of iatrogenic rebleeding when removing blood clots on the surface of ulcers, and careful selection should be made when conditions permit.
