Brief Summary
This prospective, multicenter study compares the efficacy and functional outcomes of three surgical treatments for symptomatic Goligher Grade III internal hemorrhoids: Laser Hemorrhoidoplasty (LHP), Hemorrhoid Energy Therapy (HET), and conventional closed hemorrhoidectomy (Ferguson technique). Due to strong patient preferences in hemorrhoidal surgery, this study utilizes a pragmatic, preference-tolerant design. Eligible patients will undergo standardized counseling and select their preferred treatment arm. The study aims to evaluate whether minimally invasive energy-based therapies offer superior postoperative pain relief and faster functional recovery compared to conventional hemorrhoidectomy

- Masking Details
- Due to the distinct physical nature of the surgical interventions (conventional excision vs. energy-based ablation), blinding of participants and care providers is not feasible. To minimize detection bias, the determination of recurrence and the need for re-intervention (secondary endpoint) will be adjudicated by an independent committee blinded to the treatment allocation. Additionally, data regarding patient-reported outcomes (pain, HDSS) will be collected by research staff who are not involved in the surgical procedures.
