Pelvic Pain Flashcards

1
Q

Define ectopic pregnancy

A

Ectopic pregnancy is the implantation of a pregnancy outside the endometrial cavity.
.
In the UK, 11 maternal deaths were attributed to ectopic pregnancy in the last triennial CMACE report.

Q

List types of ectopic pregnancy

A

Tubal 98% of ectopic.
haematosalpinx, tubal miscarriage, rupture
Pain (prostaglandins and blood in the peritoneal cavity).
fimbrial end (5%), ampullary section (80%), isthmus (12%),
Ovarian ectopic pregnancy
Very rare.
Laparoscopy with ovarian sparing, or medical management are the treatments of choice
Interstitial pregnancy
1–2% of ectopic pregnancies implant in the interstitial part of the tube
Morbidity higher (more vascular, more difficult to treat surgically).
Cornual pregnancy
Implantation in arudimentary horn of a bicornuate uterus.
Scar pregnancy
Abnormally adherent placenta with subsequent heavy bleeding and the high risk of uterine rupture
Abdominal ectopic pregnancy
Implantation on any organ within the peritoneal cavity. Delivery of a live baby by laparotomy have been reported

Q

What is the incidence of ectopic pregnancy

A

The incidence of ectopic pregnancy in the UK is approximately 1% .
Ectopic pregnancy rates have been strongly linked to trends in pelvic inflammatory disease or, more specifically,
Chlamydia trachomatis infection.

Q

How is an ectopic excluded on USS?

A

An intrauterine gestation sac is highly specific (99%) for exclusion of an ectopic pregnancy. ( errors psudosac, heterotopic)
Transvaginal scanning can identify most intrauterine pregnancies from when the hCG level reaches 1000 iu/l (the discriminatory level).
Early intrauterine pregnancy I
include an intrauterine sac with an echogenic rim.
A confirmed gestation sac include a yolk sac, fetal pole and fetal heart beat.

Q

How are Serial β HCG used to diagnose ectopic?

A

In early viable intrauterine pregnancies, the level of serum doubles (rises by 66% or more) approximately every 2 days
In failing intrauterine and continuing ectopic pregnancy, the doubling time for β-hCG is usually longer.
Ectopic pregnancies with a rising β-hCG is at most risk of rupture.

Q

How is Laparoscopy used to diagnose ectopic?

A

Laparoscopy is the gold-standard diagnostic tool
It involves surgical risk and should be undertaken by properly trained personnel, ideally within normal working hours.
Can miss early (small) ectopic pregnancies
Diagnosis is challenging with pelvic adhesions or hydrosalpinx.

Q

Outline the Haemodynamic assessment for ectopic pregnacy

A

Haemodynamically unstable
Rapid pulse, low blood pressure and altered conscious Urgent resuscitation

Haemodynamically stable
A careful history is taken to assess risk factors
Examination for abdominal tenderness, rebound, guarding cervical excitation
Look for signs suggestive of miscarriage such as an open cervical os or passage of products of conception.
Clinical diagnosis of ectopic pregnancy prior to tubal rupture is highly unreliable.

Q

Management of ectopic after discharge - information to give.

A

Inform women who have had an ectopic pregnancy that they can self-refer to an early pregnancy assessment service in future pregnancies if they have any early concerns.
Give all women with an ectopic pregnancy oral and written information about:
How they can contact a healthcare professional for post-operative advice if needed,
who this will be and
where and when to get help in an emergency

Q

Patient selection for Expectant management of ectopic pregnancy.

A

Clinically stable women
ultrasound diagnosis of ectopic pregnancy decreasing b-hCG level initially less than 1500 iu/l.
Initial serum b-hCG level is a key prognostic indicator
They must be willing and able to attend for follow-up, have minimal pain,.
Success rates range from 57–100% Very dependent on case selection

Q

Patient selection for Surgery /Methotrexate management of ectopic pregnancy.

A

Offer the choice of either methotrexate or surgical management to women with an ectopic pregnancy who have a serum hCG level of at least 1500 IU/litre and less than 5000 IU/litre, who are able to return for follow-up and who meet all of the following criteria:
no significant pain
an unruptured ectopic pregnancy with an adnexal mass smaller than 35 mm with no visible heartbeat no intrauterine pregnancy (as confirmed on an ultrasound scan).
Advise women who choose methotrexate that their chance of needing further intervention is increased and they may need to be urgently admitted if their condition deteriorates.

Q

How is ectopics managed surgically?

A

When surgical treatment is indicated for women with an ectopic pregnancy, it should be performed laparoscopically whenever possible, taking into account the condition of the woman and the complexity of the surgical procedure.
Surgeons providing care to women with ectopic pregnancy should be competent to perform laparoscopic surgery.

Q

When is laparotomy indicated over a laparoscopic approach in surgical management of ectopic?

A

Laparoscopic approach should be used if the patient is stable and providing suitably trained medical personnel are available.
Laparotomy is recommended in collapsed cases of ruptured ectopic pregnancy unless a very experienced laparoscopic surgeon is performing the surgery.

Q

When should salpingectomy be offered to women with an ectopic pregnancy?

A

Offer a salpingectomy to women undergoing surgery for an ectopic pregnancy unless they have other risk factors for infertility.
Consider salpingotomy as an alternative to salpingectomy for women with risk factors for infertility such as contralateral tube damage.
Inform women having a salpingotomy that up to 1 in 5 women may need further treatment. This treatment may include methotrexate and/or a salpingectomy.
For women who have had a salpingotomy, take 1 serum hCG measurement at 7 days after surgery, then 1 serum hCG measurement per week until a negative result is obtained.
Advise women who have had a salpingectomy that they should take a urine pregnancy test after 3 weeks. Advise women to return for further assessment if the test is positive.

Q

How does methotrexate work in the management of ectopic pregnancy? what are the advantages of methotrexate?

A

Methotrexate is the most widely reported medical therapy for ectopic pregnancy.
It acts as a folic acid antagonist interfering with DNA synthesis. It can be administered systemically (intravenous, intramuscular and oral) or locally (ultrasound, laparoscopic or hysteroscopic guided).
Approximately 80–92% of appropriately selected unruptured non-live ectopic pregnancies will respond to methotrexate therapy and resolve without the need for an operation.
Methotrexate vs Surgery
avoidance of the need for admission and an operation,
and the preservation of the uterine tube,
no difference has been reported in future pregnancy rates.

54
Q

Best modality for evaluating ovarian mass

A

A pelvic ultrasound is the single most effective way of evaluating an ovarian mass

55
Q

Management of premenopausal ovarian cysts

A

Women with small (less than 50 mm diameter) simple ovarian cysts generally do not require follow-up as these cysts are very likely to be physiological and almost always resolve within 3 menstrual cycles.

Women with simple ovarian cysts of 50–70 mm in diameter should have yearly ultrasound follow-up and those with larger simple cysts should be considered for either further imaging (MRI) or surgical intervention.

Ovarian cysts that persist or increase in size are unlikely to be functional and may warrant surgical management.
