Not Applicable

Conditions
Benign Ovarian Cyst

Procedure: suturing with barbed sutures during laparoscopic ovarian cystectomy
Procedure: Hemostatic agent (EVICEL®) application during laparoscopic ovarian cystectomy
Registration Number
NCT04643106
Lead Sponsor
Seoul National University Hospital
Brief Summary

This study aims to evaluate the efficacy of preservation of ovarian function, hemostasis, and safety of a hemostatic agent versus suturing during laparoscopic ovarian cystectomy for ovarian endometriosis.

Detailed Description

In women with endometrioma who plan to undergo laparoscopic ovarian cystectomy, surgical technique can influence postoperative ovarian function because of removal of normal ovarian tissue with ovarian cyst and damage to ovarian tissue during bleeding control after stripping of endometrioma. This study is designed to compare hemostatic sealant to suturing in terms of hemostatic function, safety and preservation of ovarian function.

Ovarian function of all patients will be evaluated on pre op, post op 12 weeks, post op 48 weeks by measuring AMH and ovarian volume. And Hemostatic function will be evaluated by measuring serum hemoglobin, blood loss during operation, etc.

GroupInterventionDescription
Suturing groupsuturing with barbed sutures during laparoscopic ovarian cystectomyDuring operation, barbed suture will be applied to the inner surface of ovarian parenchyme where ovarian endometriosis was attached. In this group, if bleeding is continued after suturing, additional electrocoagulation with bipolar forceps will be conducted.
Hemostatic agent groupHemostatic agent (EVICEL®) application during laparoscopic ovarian cystectomyDuring laparoscopic ovarian cystectomy, bleeding will be controlled by using a hemostatic agent (EVICEL® Fibrin Sealant, Ethicon, USA), which consist of thrombin and coagulating proteins, mainly fibrinogen and fibronectin. If hemostasis is not fulfilled enough by using it, a additional intervention such as electrocoagulation with bipolar forceps and barbed suture is required to stop bleeding.
Primary Outcome Measures
NameTimeMethod
Ovarian function preservation 12 weeks after surgery12 weeks after surgery

Reduction rate of AMH level in serum 12 weeks after surgery

Secondary Outcome Measures
NameTimeMethod
Transfusion during admissionpost-op 2 days

whether patients are transfused during admission period

the success rate of hemostasis within 10 minutesduring operation

Stop-watch will be operated right after finishing stripping endometrioma. It will be evaluated whether hemostasis is finished within 10 minutes

Ovarian function preservation 48 weeks after surgery48 weeks after surgery

Reduction rate of AMH level in serum 48 weeks after surgery

Blood loss during operationduring operation

The volume of blood loss will be estimated by using simple visual assessment technique referring to gauze count and irrigation bottle

Hemoglobinpost-op 2 days, 12 weeks and 48 weeks

Change of serum hemoglobin from baseline

Adverse events associated with operation, bleeding or transfusionpost-op 2 days

any adverse events during admission period

Hospitalization periodwithin post-op 2 weeks

days from admission day to discharge day

The time required to finish hemostasisduring operation

Stop-watch will be operated right after finishing stripping endometrioma. It will be evaluated how long the time have been spent for bleeding control

Operation running timeduring operation

time from anesthesia start to delivery of patient to recovery room
