Introduction. “One-day surgery” expands the possibilities of providing surgical care in a polyclinic with hospitalization for just one day. This area of medicine allows you to use the most effective method of treating hemorrhoids in a polyclinic – the operation hemorrhoidectomy.Aim. To substantiate the effectiveness of performing hemorrhoidectomy surgery in patients with stage 3–4 hemorrhoids in a day hospital of a polyclinic under the program “One-day surgery” with accelerated recovery of patients.Materials and methods. The main principle for performing hemorrhoidectomy surgery in a day hospital is a careful selection of patients. Closed hemorrhoidectomy with restoration of the anal canal mucosa (by Parks – Milligan – Morgan’s in the second modification of the State Research Center of Coloproctology) under spinal or general anesthesia is the surgery of choice for hemorrhoids treatment in the day patient department of a clinic. 138 surgeries were performed in the day patient department during 2 years and 10 months. After surgery, patients were placed in the surgical day-patient department wards for 3–5 hours until full activation. Then they were allowed to go home without being accompanied by a medical worker. The satisfaction of patients with the program was analyzed by a survey with a 5-point scale.Results. The timing of scheduled operations for patients has been shortened. The number of complications after hemorrhoidectomy in the early postoperative period was decreased, without long-term postoperative complications. The treatment of such patients in the surgical day-patient department demonstrated a good economic effect. The overall satisfaction with the one-day surgery program was very high (4.82). The results confirmed the effectiveness of this area of medicine.Discussion. Our experience of performing hemorrhoidectomy operations in a day surgical hospital for 3 years confirms the existence of a number of advantages over treating patients in a 24-hour hospital.Conclusions. The “One-day Surgery” and accelerated patient recovery programs expand the possibilities for treating patients with stage 4 hemorrhoids directly in the polyclinic, and thus reduce the burden on the surgical hospital.
