Comparison of the Clinical Effects of Open, Closed, and Semi-close Hemorrhoidectomy: Study Protocol for a Single-center, Prospective, Open-label and Randomized Clinical Trial.

Patients in this group undergo a hemorrhoidectomy procedure where, after external stripping and internal ligation, the surgical wound is left entirely open without sutures to heal by secondary intention. All patients receive standard postoperative care including potassium permanganate rinses and povidone-iodine disinfection.

Patients in this group undergo a hemorrhoidectomy procedure where, after achieving hemostasis, the entire surgical wound is closed primarily using interrupted non-absorbable sutures. All patients receive standard postoperative care including potassium permanganate rinses and povidone-iodine disinfection.

Patients in this group undergo a hemorrhoidectomy procedure where, after achieving hemostasis, the distal half of the incision (away from the anal canal) is closed with interrupted sutures, while the proximal half remains open. All patients receive standard postoperative care including potassium permanganate rinses and povidone-iodine disinfection.
