The Use of plasmaJet During Operative Laparoscopy for Endometriosis (PLASMA)
Endometriosis is a condition where functional endometrial tissue is present outside the uterus. It usually locates in the pelvis, which often includes the ovaries. One of the main concerns when performing surgery is to maintain fertility.
Nevertheless, a disadvantage of using monopolar and bipolar instruments for laparoscopic excision or coagulation of endometriosis lesions is the energy / thermal distribution that can cause damage to the surrounding healthy tissue. Therefore, the use of ultrasound, laser or plasma energy can potentially reduce damage to surrounding tissues and prevent adhesion formation. In addition, ablation of the internal surface of endometriomas can be an effective alternative to cystectomy.
The PlasmaJet system uses argon plasma which is released as kinetic, light and / or thermal energy. In this way the instrument can be applied within three functions, namely cutting, vaporizing and coagulating. Moreover, plasma will dissipate very quickly upon contact with tissue which consequently allows a controlled depth of tissue penetration. Thirdly, pure plasma energy differs from conventional electrosurgery since no electrical current will be spread through the tissue and therefore the thermal effect at surrounding tissues remains minimal.
The aim of this pilot study is to investigate the feasibility, effectiveness and safety of plasma energy in the treatment of endometriosis.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Other: patient group
Data is collected from women (18-45y) with endometriosis (superficial and / or deep infiltrating endometriosis) where the preferred treatment is a laparoscopic intervention at UZ Gent.
|
Data will be collected during two contact moments, in particular during her admission for surgical laparoscopy, and during her postoperative check-up.
Both of these are standard of care.
No additional questionnaires will be taken.
During the admission the postoperative pain scoreswill be monitored and collected.
The duration of her stay in the hospital will also be recorded.
During the postoperative check-up, which takes usually place six weeks after the surgery, complications will registered.
