Endometriosis is defined as the presence of endometrial [blank_start]glands and stroma[blank_end] outside the uterus.
Pathogenesis: Several theories have been proposed for the development and progression of endometriosis, yet no single one holds true for every patient or manifestation.
• [blank_start]Implant[blank_end] theory: tissue travels via retrograde menstruation or surgery/deliveries
• [blank_start]Lymphatic/vascular[blank_end] theory: explains distant location
• [blank_start]Metaplasia[blank_end] theory: undifferentiated cells transform into endometrial tissue

glands and stroma

Classification of Endometriosis:
Stages I through IV, based on visual inspection during [blank_start]laparoscopy[blank_end]:
• The appearance, [blank_start]size[blank_end], and depth of peritoneal and ovarian [blank_start]implants[blank_end]
• The presence, extent, and type of [blank_start]lesions[blank_end] (red, red-pink and clear, white, peritoneal defects and black)
• Presence, extent, and type of pelvic [blank_start]adhesions[blank_end] (ovaries and tubes) and the degree of [blank_start]cul-de-sac[blank_end] obliteration.
Respuesta

cul-de-sac
Pregunta 6
Pregunta
Laparoscopy is not required prior to medical management. Overall risk of any complication with laparoscopy, minor or major, is ~[blank_start]9[blank_end]%.
• Injury to bowel, bladder, major blood vessel
• Risk of [blank_start]bleeding[blank_end] or infection
• Risk of anaesthetic
Treatment options depend on whether [blank_start]fertility[blank_end] is desired. Medical management is based on [blank_start]hormonal[blank_end] suppression of
endometriotic lesions. Oral contraceptives are considered [blank_start]first[blank_end] line treatment and patients get significant relief of dysmenorrhea within [blank_start]4[blank_end] months. Progestins in any form can be used, cons are loss of bone [blank_start]mineral[blank_end] density, • prolonged delay in resumption of [blank_start]menses/ovulation[blank_end], and breakthrough bleeding. Mirena, a progesterone IUD results in amenorrhea in [blank_start]60[blank_end]% of patients(good).
Other options:
- Danazol. Weak [blank_start]androgen[blank_end] capable of suppressing gonadotropin secretion, leading to [blank_start]amenorrhea[blank_end]. Bad side effects: weight [blank_start]gain[blank_end], acne, hirsutism, breast [blank_start]atrophy[blank_end], virilization, impact on lipids.
- Gonadotrophin-releasing hormone (GnRH) agonists. 2 subsidized in NZ, [blank_start]goserelin acetate[blank_end] (implant) and [blank_start]leuprorelin[blank_end] (injection). For women who do not respond to oral contraceptives or progestins. Induces [blank_start]hypoestrogenism[blank_end] which causes menopausal symptoms. Cannot be used [blank_start]long[blank_end]-term (> 6 months) without hormone add-back therapy .
