AMeTHYST (AMbulatory HYsterectomy surgery). Feasibility of minimally invasive outpatient hysterectomy, a preliminary study

Abstract

Objectives: Hysterectomy, one of the most frequent surgical procedures in women, is commonly performed by a minimally-invasive approach (laparoscopic or vaginal) as recommended by the French guidelines. The French authorities aim to have 66 % of all procedures performed as same-day surgery in 2020. The aim of this study was to evaluate the feasibility and identify factors associated with success or failure of same-day surgery for minimally-invasive hysterectomy.

Study design: We conducted a prospective double-center observational study at the Caen and Amiens University Hospitals between September 2017 and May 2018 including hospitalized patients managed for a laparoscopic or vaginal hysterectomy. Patients were younger than 70 and have no major medical problems. The patients were placed into a "fit" or "unfit" group according to their Post Anaesthetic Discharge Scoring System (PADSS) score 6 h post-surgery. All the patients were asked to complete an assessment questionnaire during their hospitalization.

Results: Of the 50 included patients, half were placed in the "fit" group. A history of laparotomy was significantly predictive of failure of same-day discharge (p = 0.003) but not uterine size or Body Mass Index (BMI). The main barriers for discharge were pain (p<0.001) and postoperative nausea/vomiting (PONV) (p<0.001). Four patients, all in the "unfit" group, had Clavien-Dindo grade 1 postoperative complications.

Conclusion: Same-day minimally invasive hysterectomy is a feasible and safe procedure. Factors associated with same-day hysterectomy failure were laparotomy, pain and postoperative nausea/vomiting.
