Background:
Delayed bleeding is a frequent and serious complication after endoscopic papillectomy (EP). Second-look endoscopy (SLE) is often scheduled on the following day for wound assessment and prophylactic hemostasis, but its clinical value remains unclear.
Objectives:
This study evaluated the effectiveness of SLE in preventing delayed bleeding after EP.
Design:
This study was a multicenter, retrospective cohort study.
Methods:
We retrospectively reviewed 132 consecutive patients who underwent EP at nine high-volume centers between 2003 and 2024 (SLE group, n = 73; non-SLE group, n = 59). Propensity score matching was performed to balance baseline characteristics. The primary outcome was delayed bleeding, and secondary outcomes were risk factors, the impact of prophylactic hemostasis during SLE, and hospital stay.
Results:
After matching, 43 patients were included in each group. The incidence of delayed bleeding did not differ between the SLE and non-SLE groups (14% vs 9%, p = 0.50). Multivariate analysis identified a lack of preventive clipping closure as the only independent risk factor (odds ratio 15, 95% confidence interval 1.3-177, p = 0.030). Prophylactic hemostasis during SLE did not reduce bleeding but was associated with prolonged hospitalization (13 vs 9 days, p = 0.012).
Conclusion:
Routine SLE after EP does not reduce delayed bleeding. Moreover, prophylactic hemostasis in asymptomatic patients may unnecessarily prolong hospitalization. Hemostasis should be reserved for patients who develop clinical signs of bleeding.
