AIM: To predict the re-bleeding after endoscopic hemostasis for delayed post-endoscopic sphincterotomy(ES) bleeding.METHODS: Over a 15-year period, data from 161 patients with delayed post-ES bleeding were retrospectively collected from a single medical center. To identify risk factors for re-bleeding after initial successful endoscopic hemostasis, parameters before, during and after the procedure of endoscopic retrograde cholangiopancreatography were analyzed. These included age, gender, blood biochemistry, comorbidities, endoscopic diagnosis, presence of periampullary diverticulum, occurrence of immediate postES bleeding, use of needle knife precut sphincterotomy, severity of delayed bleeding, endoscopic features on delayed bleeding, and type of endoscopic therapy.RESULTS: A total of 35 patients(21.7%) had rebleeding after initial successful endoscopic hemostasis for delayed post-ES bleeding. Univariate analysis revealed that malignant biliary stricture, serum bilirubin level of greater than 10 mg/d L, initial bleeding severity, and bleeding diathesis were significant predictors of rebleeding. By multivariate analysis, serum bilirubin level of greater than 10 mg/d L and initial bleeding severity remained significant predictors. Re-bleeding was controlled by endoscopic therapy in a single(n = 23) or multiple(range, 2-7; n = 6) sessions in 29 of the 35 patients(82.9%). Four patients required transarterial embolization and one went for surgery. These five patients had severe bleeding when delayed post-ES bleeding occurred. One patient with decompensated liver cirrhosis died from re-bleeding.CONCLUSION: Re-bleeding occurs in approximately one-fifth of patients after initial successful endoscopic hemostasis for delayed post-ES bleeding. Severity of initial bleeding and serum bilirubin level of greater than 10 mg/d L are predictors of re-bleeding.
