Study Arms (2)

Hemostatic agent group

EXPERIMENTAL

During 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.

Procedure: Hemostatic agent (EVICEL®) application during laparoscopic ovarian cystectomy

Suturing group

ACTIVE COMPARATOR

During 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.

Procedure: suturing with barbed sutures during laparoscopic ovarian cystectomy

Interventions

During laparoscopic ovarian cystectomy, bleeding will be controlled by using a hemostatic agent (EVICEL®)

Hemostatic agent group

During laparoscopic ovarian cystectomy, suturing of ovarian inner surface will be conducted to stop bleeding

Suturing group
