Gynaecology Flashcards
(103 cards)
In a patient asking for emergency contraception, but they have severe asthma i.e. taking 25mg OD sertraline, 200 micrograms salbutamol inhaler PRN, beclomethasone 400 micrograms BD and formoterol 12 micrograms BD. What medication do you NOT give?
Ulipristal acetate
What is the pearl index?
The Pearl Index is the most common technique used to describe the efficacy of a method of contraception. The Pearl Index describes the number of pregnancies that would be seen if one hundred women were to use the contraceptive method in question for one year. 0.2 = 2/1000/year.
What is the treatment for a vaginal vault prolapse?
The treatment for vaginal vault prolapse is sacrocolpoplexy. This procedure suspends the vaginal apex to the sacral promontory. This support is usually afforded by the uterosacral ligaments.???? But this apparently uses mesh, so most appropriate may be sacrospinous fixation.
What are the 3 main routes to gain access to the pelvic organs?
1) Abdominal route
2) Vaginal route
3) Laparoscopic surgery
Explain how and when a diagnostic hysteroscopy may be completed.
How: Diagnostic hysteroscopy is when the uterine cavity is inspected with a rigid or flexible hysteroscope passed through the cervical canal. The uterine cavity is distended using carbon dioxide or saline. Anaesthetic options? Nothing, cervical local anaesthetic block, general anaesthetic.
When: Used as an adjunct to endometrial biopsy or if menstrual problems don’t respond to medical tx.
What type of biopsy would we take when we want to examine the endometrium for carcinoma?
Pipelle biopsy
How is a hysteroscopic surgery completed?
An operating hysteroscope is used (small instruments are passed down a parallel channel). Usual procedures involve TransCervical Resection of Endometrium (TCRE) or TransCervical Resection of Fibroids (TCRF) - if the fibroid is intracavity. Also for the removal of intracavity fibroids. Also for resection of the uterine septum. Usually, cutting diathermy and glycine irrigation fluid is used.
What are the complications associated with hysteroscopic surgery?
- Uterine perforation + fluid overload - unusual in an experienced surgeon
- Usually minimal blood loss
- Sterility not ensured
How is diagnostic laparoscopy performed?
Peritoneal cavity is insufflated with CO2 after passing a small hollow Veress needle through the abdominal wall. Trocar inserted through umbilicus (less damage to organs and major blood vessels). Laparoscope passed down trocar which enables visualisation of the pelvis.
When may a diagnostic laparoscopy be performed?
Used to assess macroscopic pelvic disease in Mx of pelvic pain and dysmenorrhoea (endometriosis), infertility (lap+dye test to assess tubal integrity), suspected ectopic pregnancy and pelvic masses.
How is laparoscopic surgery performed?
Multiple instruments to grasp and cut tissues are inserted through separate ports in the abdominal wall.
What are the typical indications for laparoscopy?
Removal of adhesions, areas of endometriosis, removal of ectopic pregnancy.
What are some advantages of laparoscopic surgery?
Better visualisation of tissues, faster post-op recovery, less pain, less blood loss, lower risk of infection, less heat loss, reduced hospital stay.
What is the most common major gynaecological operation?
Hysterectomy
Why are the fallopian tubes (bilateral salpingectomy) often removed when a hysterectomy is performed?
To reduce the risk of ovarian cancer as ovarian cancer often originates from the fimbral end of the fallopian tube (spreads along the peritoneal surface) and there is no use in having fallopian tubes with no uterus.
Why are the ovaries removed in a hysterectomy (bilateral oophorectomy)?
Older women
Hx of cysts
Why is hysterectomy perfomed?
- Menstrual disorders
- Endometriosis
- Fibroids
- Chronic PID
- Prolapse
- Pelvic malignancy
- Typically last resort
What are the different types of hysterectomy?
1) Total abdominal hysterectomy
2) Subtotal hysterectomy
3) Vaginal hysterectomy
4) Laparoscopic hysterectomy (laparoscopic-assisted vaginal hysterectomy, total laparoscopic hysterectomy)
5) Wertheim’s (radical) hysterectomy
What are the indications for Total Abdominal Hysterectomy?
Malignancy - ovarian or endometrial (in conjunction with laparotomy)
Very large or immobile uterus
When abdominal inspection is required
What are the indications for Subtotal hysterectomy?
When you don’t want to damage the ureters or bladder?
What is a disadvantage of the subtotal hysterectomy?
- Still worried about cervical cancer as cervix remains in the pt
- Contraindicated in patients with abnormal smear Hx
- May still have menstrual spotting after if small amounts of endometrium remain in the cervical canal
What are indications for vaginal hysterectomy?
Uterine prolapse. Moderate enlargement of uterus?.
What are the advantages of vaginal hysterectomy?
Lower morbidity, quicker recovery, lower risk infection, blood loss etc. Least invasive.
How might a subtotal hysterectomy be completed?
Performed laparoscopically and uterine body removed from the peritoneal cavity using a morcellator instrument.
