Reproducibility of Minimally Invasive Surgery for Grade III Hemorrhoids

Hemorrhoids are vascular-elastic structures of the anal canal that contribute to continence. Their enlargement and descent lead to symptoms such as rectal bleeding and the sensation of anal swelling, known as hemorrhoidal syndrome. In advanced cases (Goligher Grade III-IV), surgery is the only effective treatment. Open excisional hemorrhoidectomy (OEH), based on the Milligan-Morgan technique, is the standard procedure. Although effective in the long term, it causes severe postoperative pain. Minimally invasive surgery (MIS) employs enhanced visualization devices to improve surgical precision and reduce tissue damage. While widely used in specialties with small surgical fields, it has not yet been explored in anal surgery. Its advantages include reduced tissue injury and improved healing, although it presents a learning curve and an initially longer surgical time. The IDEAL framework evaluates surgical innovations in five stages: Idea, Development, Exploration, Evaluation, and Long-Term Study. The IDEAL phase 2a is aimed at the optimization and technical definition of surgical innovation with a focus on continuous improvement based on real clinical practice, laying the foundation for broader and more rigorous subsequent studies. Since no previous studies on the application of MIS in OEH have been found, the investigators propose a study within Stage 2A of the IDEAL model to assess the reproducibility of this technique. The investigators believe its incorporation into open excisional hemorrhoidectomy could result in less postoperative pain and faster patient recovery.
