Benefit of Hemostatic Sealant in Preservation of Ovarian Reserve

Not Applicable
Not yet recruiting
Conditions
Benign Ovarian Cyst
Cystectomy
Interventions
Procedure: Coagulation by FLOSEAL haemostatic agent
Procedure: Bipolar coagulation
Registration Number
NCT05037552
Lead Sponsor
University Hospital, Montpellier
Brief Summary

Introduction : The most common technique used for ovarian cystectomy is the stripping technique. After stripping the cyst wall, the subsequent bleeding of the ovarian stromal wound is usually controlled by bipolar coagulation or/and by suturing. However, hemostasis achieved with bipolar coagulation could result in damage to the ovarian reserve. To avoid damage to healthy ovarian tissue, hemostasis using various topical hemostatic agents has been introduced to control post- cystectomy ovarian wound bleeding. Among these, FloSeal (Baxter Healthcare Corporation, Deer- field, IL, USA) is a hemostatic sealant composed of a gelatin-based matrix and thrombin solution.

Aim: The aim of the study is to evaluate the impact of topical hemostatic sealants and bipolar coagulation during laparoscopic ovarian benign cyst resection on ovarian reserve by comparing the rates of decrease in anti- Müllerian hormone (AMH).

Methods: A randomized prospective data collection was made on women aged 18-45 years who planned to have laparoscopic ovarian cystectomy at one of two institutions (n = 80), Montpellier University Hospital and Nimes University Hospital, France. Patients were randomly divided into two groups treated with either a topical hemostatic sealant (Floseal) or bipolar coagulation for hemostasis. Preoperative, 3-month and 6-month postoperative AMH levels were checked and the rates of decrease of AMH were compared.

GroupInterventionDescription
FLOSEALCoagulation by FLOSEAL haemostatic agentFLOSEAL® is a hemostatic agent based on gelatin of bovine origin added to thrombin of human origin. It is a recommended medical device in surgical procedures as an adjunct to hemostasis when control of bleeding, arterial jet seepage, ligation or any other conventional method proves impractical or ineffective. During this study, it will be used in 1st intention.
BIPOLAR FORCEPSBipolar coagulationThe bipolar forceps allow electrocoagulation and are part of the standard laparoscopy box, delivered by the sterilization service to the gynecology operating room.
Primary Outcome Measures
NameTimeMethod
Serum anti-Mullerian hormone (AMH) level at 3 months3 months after the cystectomy

A biological assessment with determination of the serum AMH level will be carried out for each patient, 3 months postoperatively.

Serum anti-Mullerian hormone (AMH) level preoperativeBetween 2 and 17 days before cystectomy

A biological assessment with determination of the serum AMH level will be carried out for each patient during the preoperative consultation.

Serum anti-Mullerian hormone (AMH) level at 6 months6 months after the cystectomy

A biological assessment with determination of the serum AMH level will be carried out for each patient, 6 months postoperatively.

Secondary Outcome Measures
NameTimeMethod
Revision surgery for bleeding at the operative siteFrom the end of the cystectomy to the end of hemostasis

In the event of bleeding at the operative site, revision surgery may be necessary. In this case the information will be collected.

Time to achieve hemostasisFrom the end of the cystectomy to the end of hemostasis (up to 1 hour)

The time is measured in minutes from the end of the cystectomy to the end of hemostasis.

Use of additional hemostatsis techniqueFrom the end of the cystectomy to the end of hemostasis, during surgery

Another technique can be used to achieve hemostasis: bipolar forceps, suture or second hemostasis agent. The other technique will be specified if it is used

Blood lossFrom the start of the surgery to the end of hemostasis

Blood loss will be measured in ml throughout the surgery.

Intraoperative adverse effectsFrom the end of the cystectomy to the end of hemostasis

Adverse effects related to the coagulation procedure will be collected.
