Therapeutic Efficacy of Erbium:YAG Laser in Postpartum Patients With Episiotomy Scars in Respect of Genital Pelvic Pain and Scar Tissue Healing: A Randomized Sham-Controlled Prospective Study
Therapeutic Efficacy of Erbium:YAG Laser in Postpartum Patients With Episiotomy Scars in Respect of Genital Pelvic Pain and Scar Tissue Healing: A Randomized Sham-Controlled Prospective Study
Episiotomy is a planned surgical incision to the perineum and posterior wall of the vagina during the second stage of labor. The fibrotic and sclerotic scar tissue formed as part of the healing process of episiotomies may cause pain. Therefore, episiotomy is associated with sexual dysfunction due to the painful sexual intercourse, chronic pain and infections and scarring in long term. Er:YAG laser is a safe option for the treatment of vulvar pain.
Er:YAG laser is a non-invasive and non-ablative procedure that strengthens the connective tissue in the vaginal wall. It provides controlled thermal energy and causes shrinkage of collagen fibrils of the vaginal epithelium and lamina propria. It also induces neocollagenesis, elastogenesis and neoangiogenesis by temperature change. Er:YAG laser is also an effective modality to treat the scar tissue formed after the mediolateral episiotomy since it is a matter of functionality and esthetics. By tissue remodeling effect Er:YAG laser will improve the scar tissue of episiotomy and ameliorate the vulvar pain.
In this study, the therapeutic effect of Er:YAG laser on the tissue healing of the episiotomy scars and the reduction of vulvar pain.
Episiotomy is a planned surgical incision to the perineum and posterior wall of the vagina during the second stage of labor. The fibrotic and sclerotic scar tissue formed as part of the healing process of episiotomies may cause pain. Therefore, episiotomy is associated with sexual dysfunction due to the painful sexual intercourse, chronic pain and infections and scarring in long term. 40% of the patients complain about persisted dyspareunia after 6 months of delivery. Genital pelvic pain/penetration disorders disturb the quality of sexual life of the couple and affect the psychology and wellbeing of the partners. Since, vulva is rich in afferent nerve endings, episiotomy scar healing is associated with pain. Er:YAG laser is a safe option for the treatment of vulvar pain.
Er:YAG laser is a non-invasive and non-ablative procedure that strengthens the connective tissue in the vaginal wall. It provides controlled thermal energy and causes shrinkage of the collagen fibrils in the vaginal epithelium and lamina propria. It also induces neocollagenesis, elastogenesis and neoangiogenesis by temperature change. With minimum damage to the peripheral tissue, the viable cells in the target tissue react to this temperature change by expressing heat shock proteins (HSP). Then, HSP increases the levels of transforming growth factor-beta, fibroblast growth factor, epidermal growth factor, platelet-derived growth factor, vascular epithelial growth factor which induce neocollagenesis and neoangiogenesis. Therefore, the thermal energy stored in the vaginal wall induces proliferation of the epithelium which is rich in glycogen, neovascularization and collagen production in the lamina propria. Er:YAG laser is also an effective modality to treat the scar tissue formed after the mediolateral episiotomy since it is a matter of functionality and esthetics. By tissue remodeling effect Er:YAG laser will improve the scar tissue of episiotomy and ameliorate the vulvar pain.
In this study, the therapeutic effect of Er:YAG laser on the tissue healing of the episiotomy scars and the reduction of vulvar pain.
