The study, Effect of Listening to Standardized Music Sequences on Preventing Postoperative Pain in Proctologic Surgery, aims to evaluate the impact of preoperative listening to standardized music sequences on postoperative pain in patients undergoing proctologic surgery (for hemorrhoids, fistulas, or anal fissures). This research will assess the influence of preoperative music on postoperative pain management, the use of analgesics after surgery and during the following month, and its effect on the quality of life post-surgery. MUSICO-PROCTO is an interventional, randomized study involving two groups (patients will be randomly assigned to either the music intervention or control group). The study is monocentric, conducted at Clinique Saint Vincent in France, and includes 550 participants. Participants will be followed for 28 days, while the overall study duration will span 28 months. To participate, individuals must: Be aged 18 or older. Be affiliated with a social security system. Provide signed informed consent. Undergo proctologic surgery for hemorrhoids, fistulas, or anal fissures. This study seeks to explore the potential of music as a complementary method to improve postoperative outcomes.
