Hystérectomie pour pathologie bénigne : choix de la voie d’abord, technique de suture vaginale et morcellement : recommandations

[Feasibility and security of laparoscopic (± robotic) total hysterectomy in outpatient surgery: A French multicenter retrospective study]

OBJECTIVE

To assess the feasibility and safety of total hysterectomy by laparoscopic approach (± robot assisted) in ambulatory.

MATERIALS AND METHODS

French three-center retrospective study including 165 patients who had laparoscopic (± robot assisted) total hysterectomy scheduled as outpatients from January 2016 to December 2020. Clinical and perioperative data were collected. Factors associated with outpatient failure and rehospitalization were evaluated.

RESULTS

The outpatient success rate was 92.7%. Factors associated with outpatient failure were incision time>13:00, large volume of blood loss, intraoperative complications with Oslo score≥2, uterine weight≥250g, indication for benign pathology, and robot-assisted approach. Among patients managed as outpatients, 7.2% were rehospitalized at a mean of 10 days from surgery. The factors associated with rehospitalization were the use of an effective antiaggregant or anticoagulant treatment and the use of intraoperative adhesiolysis. Four patients (2.6%) underwent revision surgery.

CONCLUSION

Minimally invasive hysterectomy can be performed as an outpatient procedure even in cases of malignant pathology. Age and body mass index are not associated with an increased risk of failure or re-hospitalization within one month.

Should we perform subtotal hysterectomy associated with sacral colpopexy for genital prolapse to prevent the risk of endometrial cancer?

OBJECTIVE

In a menopausal woman scheduled for curative surgery for pelvic organ prolapse (POP) by sacral colpopexy (SC), the question of concomitant hysterectomy is frequently considered by the surgeon. The risk of endometrial cancer (EC) exists in this population, and increases with age and body mass index. The French college of gynecologists and obstetricians (CNGOF) decided to issue good practice guidelines on subtotal hysterectomy (SH) for postmenopausal women scheduled for SC for POP.

METHODS

The CNGOF has decided to adopt the AGREE II and GRADE systems for grading scientific evidence. Each recommendation for practice was allocated a grade, which depends on the quality of evidence (QE) (clinical practice guidelines).

RESULTS

The prevalence of occult endometrial cancer (EC) found on pathological analysis after SH in this context (concomitant SH associated with SC) is low (<1%) (QE: high). Few studies have assessed the value of preoperative uterine exploration. Performing SH during SC is associated with its own risks, which may diminish the potential "carcinological prevention benefit". Uterine morcellation, performed by laparoscopy or a robot-assisted procedure, is associated with a low risk (<0.6%) of dissemination of an unknown sarcoma/EC (QE: moderate) A risk of dissemination of parasitic myomas (<0.5%) is also possible (QE: moderate).

CONCLUSION

It is not recommended to perform a subtotal hysterectomy associated with sacral colpopexy for the sole purpose of reducing the occurrence of endometrial cancer (Recommendation: STRONG [GRADE 1-]; the level of evidence was considered to be low and the risk-benefit balance was considered not to be favorable).

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

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.

[What haemostatic technique should we use for opportunistic salpingectomy during benign laparoscopic hysterectomy?]

OBJECTIVE

To compare ovarian function before and after laparoscopic hysterectomy with bilateral salpingectomy for benign lesions with two different systems of haemostasis.

METHODS

In this prospective randomized study comparing two types of energy used for coagulation in bilateral salpingectomy (group A: bipolar electric energy, versus group B: ultrasonic advanced energy [Harmonic^®]), forty consecutive non-menopausal patients undergoing laparoscopic hysterectomy for benign lesions were included. Values of anti-Müllerian hormone (AMH), LH and FSH, antral follicle count (AFC) and ovarian vascularization on bilateral Doppler ultrasound, quality of life (questionnaire) were assessed preoperatively and at 1 and 3 months postoperatively.

RESULTS

Preliminary analysis showed shorter salpingectomy operating time (P<0.0001) and less bleeding (P<0.005) in group B. In group A, there was no statistical difference except a decrease in AFC at 1 and 3 months on the right ovary (P=0.04). In group B, AMH levels were significantly lower postoperatively at 3 months and LH levels were increased at 3 months (respectively P=0.02 et P=0.04). There was no statistical difference in the ultrasonographic data. Quality of life did not significantly differ in both groups.

CONCLUSION

Preliminary findings showed reduced AMH levels at 3months postoperatively in ultrasonic energy group whereas there was no significative menopausal symptoms. It seems important to continue this study in order to know the real effects of both energy systems on the ovarian function.

Safety and Efficacy of Advanced Bipolar Vessel Sealing in Vaginal Hysterectomy: 1000 Cases

STUDY OBJECTIVE

To determine the safety and efficacy of advanced electrothermal bipolar vessel sealing (EBVS) during vaginal hysterectomy by evaluating urinary complications, overall complications, and reoperation rate.

DESIGN

A retrospective cohort (Canadian Task Force classification III).

SETTING

High-volume gynecologic surgeon practice, private hospital.

PATIENTS

One thousand consecutive patients who have undergone vaginal hysterectomy for benign conditions carried out with EBVS between January 2002 and December 2012.

INTERVENTIONS

Vaginal hysterectomy performed using an EBVS device.

MEASUREMENTS AND MAIN RESULTS

One thousand consecutive patients underwent vaginal hysterectomy with advanced EBVS between January 2002 and December 2012 with an average age of 51.4 ± 8.9 years (range, 31-88) and mean weight and body mass index of 57.4 ± 7.2 kg (range, 42-105) and 25.8 ± 4.2 kg/m² (range, 19.1-38.9), respectively. Eighty-five percent of patients (852/1000) were healthy without any severe systemic disease. A single experienced surgeon performed all vaginal hysterectomies with EBVS, specifically by not applying traction during thermofusion to avoid hemorrhage, amputating the cervix to transform the uterus to an apple shape to facilitate a vaginal approach and rotation of the uterus, and placing bi-clamp forceps on the edge of the uterus and not at a 45- or 90-degree angle. Wound closure was completed with a continuous suture. Eleven urinary complications (1.1%) were recorded (10 bladder mechanical injuries and 1 vesicovaginal fistula). This was not statistically different from the rate of .64% previously reported in the FINHYST study (p = .15). The overall rate of complications was 5.3%, and 20 patients (2.0%) required reoperation. The presence of uterine scar tissue (odds ratio, 5.5; 95% confidence interval, 1.6-19.2) and larger uterus size (odds ratio, 2.5; 95% confidence interval, 1.01-19.2) were associated with a higher risk of urinary complications.

CONCLUSION

The use of EBVS during vaginal hysterectomy results in urinary and overall complication rates of 1.1% and 5.3%, respectively, statistically similar to previously reported series that did not use EBVS. The use of advanced EBVS is a safe and effective method of achieving hemostasis during vaginal hysterectomy.

[Hysterectomy for benign pathology: Guidelines for clinical practice]

OBJECTIVE

The objective of the study was to provide guidelines for clinical practice from the French college of obstetrics and gynecology (CNGOF), based on the best evidence available, concerning hysterectomy for benign pathology.

METHODS

Each recommendation for practice was allocated a grade which depends on the level of evidence (guidelines for clinical practice method).

RESULTS

Hysterectomy should be performed by a high volume surgeon (>10 procedures of hysterectomy per year) (grade C). Rectal enema stimulant laxatives are not recommended prior to hysterectomy (grade C). It is recommended to carry out vaginal disinfection using povidone iodine solution prior to an hysterectomy (grade B). Antibioprophylaxis is recommended during a hysterectomy, regardless of the surgical route (grade B). The vaginal or the laparoscopic routes are recommended for hysterectomy for benign pathology (grade B), even if the uterus is large and/or the patient is obese (grade C). The choice between these two surgical approaches depends on others parameters, such as the surgeon's experience, the mode of anesthesia and organizational constraints (operative duration and medico economic factors). Hysterectomy by vaginal route is not contraindicated in nulliparous women (grade C) or in women with previous c-section (grade C). No specific technique to achieve hemostasis is recommended with a view to avoid urinary tract injuries (grade C). In the absence of ovarian pathology and personal or family history of breast/ovarian carcinoma, it is recommended to conserve ovaries in pre-menopausal women (grade B). Subtotal hysterectomy is not recommended in order to diminish the risk of per- or postoperative complications (grade B).

CONCLUSION

The application of these recommendations should minimize risks associated with hysterectomy.
