Purpose: Standard therapy for grade III hemorrhoids is rubber band ligation (RBL) and hemorrhoidectomy. The long-term clinical and patient-reported outcomes of these treatments in a tertiary referral center for proctology were evaluated.
Methods: A retrospective analysis was performed in all patients with grade III hemorrhoids who were treated between January 2013 and August 2018. Medical history, symptoms, reinterventions, complications, and patient-reported outcome measurements (PROM) were retrieved from individual electronic patient files, which were prospectively entered as standard questionnaires in our clinic.
Results: Overall, 327 patients (163 males) were treated by either RBL (n=182) or hemorrhoidectomy (n=145). The median follow-up was 44 months. The severity of symptoms and patient preference led to the treatment of choice. The most commonly experienced symptoms were prolapse (83.2%) and blood loss (69.7%). Hemorrhoidectomy was effective in 95.9% of the cases as a single procedure, while a single RBL procedure was only effective in 51.6%. In the RBL group, 34.6% received a second RBL session. Complications were not significantly different, 11 (7.6%) after hemorrhoidectomy versus 6 (3.3%) after RBL. However, 4 fistulas developed after hemorrhoidectomy and none after RBL (P<0.05). The pre-procedure PROM score was higher in the hemorrhoidectomy group whereas the post-procedure PROM score did not significantly differ between the groups.
Conclusion: Treatment of grade III hemorrhoids usually requires more than one session RBL whereas 1-time hemorrhoidectomy suffices. Complications were more common after hemorrhoidectomy. The patient-related outcome did not differ between procedures.
