Outpatient surgical management has been developing in recent years and High Authority of Health recommendations in French for this type of management is a postoperative pain score of less than 3 on the VAS.

The feasibility and safety of laparoscopy is well established, particularly in the field of gynecology, but this technique often causes postoperative pain. Techniques are being developed to reduce postoperative pain in laparoscopic surgery. Low pressure insufflation (7 to 10 mmHg) compared to standard pressure insufflation (12 to 15 mmHg) significantly reduces postoperative pain. Microcoelioscopy (use of 3 mm trocars instead of 5 to 12 mm trocars in standard laparoscopy), by reducing the size of incisions, also significantly reduces postoperative pain.

The Low Impact Laparoscopy is a minimally invasive technique that combines low pressure insufflation and microcoelioscopy which would have the advantage of reducing postoperative pain. This technique would therefore, by reducing postoperative pain, to improve outpatient management, particularly in cases of hysterectomies for which the outpatient management rate could be increased.

The hypothesis is that using the Low Impact Laparoscopy concept would increase outpatient management rate compared to conventional laparoscopy in gynecological surgeries for hysterectomy.

The study aims to compare the Low Impact Laparoscopy concept with conventional laparoscopy in terms of ambulatory care rates in patients undergoing surgery for hysterectomy.
