BACKGROUND: The management of hemorrhoidal disease (HD) in patients with bleeding disorders (BD) is challenging. Polidocanol foam sclerotherapy (PFS) is associated with a low rate of bleeding complications. The aim of this study was to compare the efficacy and safety of PFS in the treatment of HD in patients with and without BD. METHODS: This prospective, multicenter, cohort study enrolled patients with (group B) and without (group A) BD, with symptomatic internal HD grades I–III over an 18-month period. All patients were treated with PFS. Patients with congenital BD did not undergo prior replacement therapy and those with acquired BD due to antithrombotic drugs, did not discontinue therapy. Efficacy outcomes included therapeutic success and HD recurrence during a 1-year follow-up period. To evaluate safety the complications related to PFS were recorded. RESULTS: We included 228 patients (group A: 155, group B: 73; male/female: 114/114; mean age: 59.4 ± 15.9 years). The baseline hemorrhoidal disease bleeding grade (p < 0.001) and Sodergren hemorrhoidal symptom severity score (p = 0.019) were higher for group B. The overall therapeutic success rate was 93.4% with an average number of sessions of 1.51 ± 0.74, significantly higher for group B (1.68 ± 0.86 vs 1.43 ± 0.65, p = 0.013). Complications occurred in 11.4% of the patients, with bleeding reported in 4.8%. The majority of complications were mild (96.2%). No significant differences between the two groups were observed for therapeutic success, recurrence, or complication rate. CONCLUSIONS: Patients with BD may have more symptomatic HD at baseline. Even so, PSF showed similar effectiveness and safety in patients with BD compared to patients without BD.
