Question 101: A 45-year-old woman presents to her GP with heavy menstrual bleeding for 8 months. She reports flooding through pads every 2 hours and passing large clots. Her haemoglobin is 92 g/L. Physical examination including bimanual pelvic examination is unremarkable. According to NICE guidelines for the management of heavy menstrual bleeding, what is the most appropriate initial investigation?
A. Full blood count and ferritin levels (Correct Answer)
B. Transvaginal ultrasound scan
C. Pelvic MRI scan
D. Endometrial biopsy
E. Hysteroscopy
Explanation: ***Full blood count and ferritin levels***- According to **NICE guidelines (NG88)**, for heavy menstrual bleeding with an **unremarkable physical examination**, the initial laboratory assessment must include a **Full Blood Count** to screen for anaemia.- This patient already shows a low haemoglobin (92 g/L); assessing **ferritin** further evaluates **iron stores**, which is critical for managing systemic effects of persistent bleeding and guiding iron supplementation.*Transvaginal ultrasound scan*- This is the first-line **imaging** modality but is typically reserved for cases where there is a **palpable mass**, clinical suspicion of structural pathology (like fibroids), or if initial medical treatment fails.- As this patient's bimanual examination is **unremarkable** and the focus is on initial *investigation* for the consequences of bleeding, immediate imaging is not the *first* step before blood work.*Pelvic MRI scan*- MRI is not a routine initial investigation for heavy menstrual bleeding and is generally used for complex cases such as **adenomyosis** or surgical planning for large **fibroids**, after other investigations.- It is far more expensive and less accessible than the required initial blood tests or ultrasound, making it unsuitable as the *most appropriate initial* investigation.*Endometrial biopsy*- Indicated primarily in women over **45 years old** with persistent bleeding or those with risk factors for **endometrial hyperplasia** or malignancy.- While this patient is 45 and has persistent bleeding, the NICE guidance prioritizes initial assessment of systemic impacts (anaemia) and general structural screening via ultrasound or hysteroscopy before tissue sampling, unless specific red-flag risks are strongly present.*Hysteroscopy*- This is recommended if the history suggests **submucous fibroids**, polyps, or if ultrasound is inconclusive/unavailable and structural pathology is still suspected.- It is an an invasive procedure and is not the indicated **initial** step for a woman with a normal pelvic examination and no immediate red-flag symptoms requiring direct visualization.
Question 102: A 49-year-old woman presents with a 4-month history of irregular heavy bleeding. She reports cycles ranging from 18 to 60 days. Her BMI is 38 kg/m² and she has type 2 diabetes controlled with metformin. Transvaginal ultrasound shows endometrial thickness of 22mm with a bulky uterus but no focal lesions. Endometrial biopsy shows complex endometrial hyperplasia without atypia. She has completed her family. What is the most appropriate management?
A. Total hysterectomy with bilateral salpingo-oophorectomy
B. Continuous oral progestogen therapy for 6 months then re-biopsy
C. Cyclical oral progestogen therapy
D. Insert levonorgestrel intrauterine system and re-biopsy at 6 months (Correct Answer)
E. Repeat endometrial biopsy in 3 months
Explanation: ***Insert levonorgestrel intrauterine system and re-biopsy at 6 months***
- For **complex endometrial hyperplasia without atypia**, the **levonorgestrel intrauterine system (LNG-IUS)** is the first-line treatment, delivering high local progestogen concentrations that are more effective at causing regression than oral therapies.
- A **repeat endometrial biopsy at 6 months** is essential to confirm the resolution of hyperplasia and monitor for any persistence or progression, which is crucial given the patient's risk factors.
*Total hysterectomy with bilateral salpingo-oophorectomy*
- **Hysterectomy** is generally reserved for patients with **atypical endometrial hyperplasia** or those with non-atypical hyperplasia who fail conservative medical management.
- This patient's **high BMI** and **diabetes** increase surgical and anesthetic risks, making a less invasive initial treatment more appropriate.
*Continuous oral progestogen therapy for 6 months then re-biopsy*
- While an acceptable alternative, **continuous oral progestogens** are considered second-line due to **lower efficacy** and a higher incidence of **systemic side effects** compared to the localized delivery of the LNG-IUS.
- Adherence to daily oral medication can be challenging, potentially leading to suboptimal regression rates of the **hyperplastic endometrium**.
*Cyclical oral progestogen therapy*
- **Cyclical progestogens** are significantly **less effective** than continuous therapy and are not recommended for the treatment of **endometrial hyperplasia**.
- Continuous exposure to progestogen is required to effectively counteract the **unopposed estrogen** driving endometrial proliferation and induce atrophy.
*Repeat endometrial biopsy in 3 months*
- Simply observing with a **repeat biopsy** without active treatment is inappropriate for symptomatic **endometrial hyperplasia without atypia**, especially with significant risk factors like **obesity** and **diabetes**.
- This approach delays necessary intervention and increases the risk of the condition persisting or potentially progressing, although the immediate risk of malignancy without atypia is low.
Question 103: A 38-year-old woman presents with a 9-month history of progressively worsening heavy menstrual bleeding and pressure symptoms. Transvaginal ultrasound shows a 9 cm subserosal fibroid arising from the posterior uterine wall. She has completed her family but wishes to retain her uterus. She has no significant medical history. Which factor would most strongly favour recommending myomectomy over uterine artery embolisation in this patient?
A. Age under 40 years
B. Completed family size
C. Presence of pressure symptoms
D. Single large fibroid location (Correct Answer)
E. Size of fibroid greater than 8 cm
Explanation: ***Single large fibroid location***- A **subserosal pedunculated fibroid**, especially one with a narrow stalk, is a relative contraindication for **uterine artery embolisation (UAE)** due to the high risk of **stalk necrosis**, detachment, and subsequent peritonitis or infection.- **Myomectomy** is the preferred surgical approach for a single, accessible subserosal fibroid, providing definitive removal with a lower risk of post-procedural complications and allowing for pathological assessment compared to UAE in this specific anatomical location.*Age under 40 years*- While **myomectomy** is often preferred in younger women who desire future fertility, age under 40 years itself does not strictly dictate the choice between surgery and UAE when both options for **uterine preservation** are available and fertility is not a primary concern.- Both procedures are viable for a 38-year-old; the decision often hinges on fibroid characteristics and patient preference, not solely age.*Completed family size*- This factor typically broadens treatment options to include **hysterectomy** or makes **UAE** more acceptable, as the primary concern for future pregnancy is removed.- Since the patient specifically wishes to **retain her uterus**, this factor does not inherently favor myomectomy over UAE; both techniques satisfy her request for uterine preservation.*Presence of pressure symptoms*- Both **myomectomy** and **UAE** are effective at reducing the volume of fibroids and alleviating **bulk symptoms** and pelvic pressure.- While myomectomy provides immediate physical removal, UAE leads to progressive shrinkage, meaning this symptom alone does not strongly favor one over the other.*Size of fibroid greater than 8 cm*- A **9 cm fibroid** is considered large but can be managed by both UAE and myomectomy; however, very large fibroids (e.g., >10 cm) may have a higher failure rate or slower symptom resolution with UAE.- Size alone is less of a deciding factor than the **subserosal pedunculated** nature of the fibroid, which carries specific embolization risks and makes myomectomy more advantageous for definitive removal.
Question 104: A 21-year-old woman presents with sudden onset severe left-sided abdominal pain and vaginal spotting. She has a history of pelvic inflammatory disease 2 years ago. She is sexually active and uses condoms inconsistently. Her last menstrual period was 5 weeks ago. On examination, she is pale, blood pressure 85/50 mmHg, heart rate 115 bpm. She has generalised abdominal tenderness with guarding and rebound. A bedside pregnancy test is positive. What is the single most important immediate step in management?
A. Arrange emergency laparoscopy
B. Commence intravenous fluids and cross-match blood (Correct Answer)
C. Obtain consent for blood transfusion
D. Perform transvaginal ultrasound
E. Request serum beta-hCG level
Explanation: ***Commence intravenous fluids and cross-match blood***
- The patient presents with classic signs of **haemorrhagic shock** (pallor, hypotension, tachycardia) and **peritonism** in early pregnancy, highly suggestive of a **ruptured ectopic pregnancy**.
- The single most important immediate step is to follow the **ABC (Airway, Breathing, Circulation)** approach, prioritizing **circulatory support** through large-bore intravenous access, rapid fluid resuscitation, and preparing blood for transfusion by cross-matching.
*Arrange emergency laparoscopy*
- While an **emergency laparoscopy** is the definitive treatment for a ruptured ectopic pregnancy, it cannot be safely undertaken until the patient's **hemodynamic stability** is initiated through aggressive resuscitation.
- Surgical intervention requires the patient to be as stable as possible; attempting surgery without prior **volume replacement** significantly increases risk.
*Obtain consent for blood transfusion*
- **Consent** for blood transfusion is crucial but is an administrative step that can occur concurrently with or immediately after initiating life-saving **resuscitation**.
- The absolute priority is to *begin* fluid and blood product preparation (**cross-matching**) and administration, rather than just obtaining consent for future administration.
*Perform transvaginal ultrasound*
- In a **hemodynamically unstable** patient with clear clinical signs of a ruptured ectopic pregnancy (shock, peritonism, positive pregnancy test), performing a **transvaginal ultrasound** would cause a dangerous and potentially fatal delay.
- The diagnosis is **clinical** in this emergent situation; ultrasound is reserved for *stable* patients where the diagnosis is less certain.
*Request serum beta-hCG level*
- A **bedside urine pregnancy test** is already positive, confirming pregnancy. Requesting a quantitative **serum beta-hCG** level provides no additional immediate management benefit in a patient in shock.
- Waiting for **laboratory results** for a confirmed pregnancy in a crashing patient delays crucial **resuscitation** and surgical preparation without changing the immediate management plan.
Question 105: A 30-year-old woman presents with 7 weeks amenorrhoea and light vaginal bleeding. Transvaginal ultrasound shows an empty uterus with endometrial thickness of 8mm and a heterogeneous adnexal mass measuring 22mm. Serum beta-hCG is 1850 IU/L. A repeat scan 48 hours later shows the same findings and beta-hCG is now 1920 IU/L. She is clinically stable. What is the most likely diagnosis?
A. Complete miscarriage
B. Ectopic pregnancy (Correct Answer)
C. Incomplete miscarriage
D. Intrauterine pregnancy too early to visualise
E. Pregnancy of unknown location
Explanation: ***Ectopic pregnancy***
- The presence of an **empty uterus** despite a serum **beta-hCG** level above the **discriminatory zone** (typically 1500-2000 IU/L) along with a **heterogeneous adnexal mass** strongly indicates an ectopic pregnancy.
- The **suboptimal rise in beta-hCG** over 48 hours (from 1850 to 1920 IU/L, far less than the expected 66% increase for a viable intrauterine pregnancy) further confirms an abnormal pregnancy, consistent with an ectopic location.
*Complete miscarriage*
- In a **complete miscarriage**, serum **beta-hCG levels** would be expected to **fall significantly** (typically >50% within 48 hours), not remain plateaued or slightly increase.
- An ultrasound would show an **empty uterus** without the presence of an associated **adnexal mass**.
*Incomplete miscarriage*
- An **incomplete miscarriage** is characterized by the presence of **retained products of conception** within the uterine cavity, which would be visible on ultrasound, contradicting the finding of an **empty uterus**.
- Clinical presentation often includes **heavier bleeding** and an **open cervical os**, which is not the case here (light bleeding, clinically stable).
*Intrauterine pregnancy too early to visualise*
- For a **beta-hCG level** of 1850-1920 IU/L, a gestational sac should be clearly visible via **transvaginal ultrasound** if the pregnancy were intrauterine, as this is above the standard **discriminatory zone**.
- The presence of a **heterogeneous adnexal mass** in conjunction with an empty uterus rules out a viable early intrauterine pregnancy and points to an extrauterine location.
*Pregnancy of unknown location*
- **Pregnancy of unknown location (PUL)** is a provisional diagnosis used when transvaginal ultrasound does not identify either an intrauterine pregnancy or an extrauterine pregnancy.
- In this case, a **heterogeneous adnexal mass** was identified in the adnexa, which localizes the pregnancy and allows for a more specific diagnosis of **ectopic pregnancy**.
Question 106: A 42-year-old woman presents with a 1-year history of heavy menstrual bleeding. She reports using 8-10 pads per day for 6 days each cycle. Examination reveals a 16-week size uterus with irregular contour. Transvaginal ultrasound confirms multiple intramural fibroids, the largest measuring 7 cm. Haemoglobin is 95 g/L. She wishes to avoid hysterectomy if possible. She has completed her family. Which treatment option provides the best long-term symptom control while avoiding major surgery?
A. Endometrial ablation
B. Gonadotrophin-releasing hormone analogues
C. Levonorgestrel intrauterine system
D. Uterine artery embolisation (Correct Answer)
E. Ulipristal acetate
Explanation: ***Uterine artery embolisation***
- **Uterine artery embolisation (UAE)** is a minimally invasive procedure that effectively treats multiple large fibroids by obstructing blood supply, reducing volume, and significantly improving **heavy menstrual bleeding**.
- It is the best long-term non-surgical option for a patient with a **16-week size uterus** who has completed her family and wishes to avoid major surgery like a hysterectomy.
*Endometrial ablation*
- This procedure is generally **contraindicated** when the uterus is enlarged beyond **10-12 weeks size** or when intramural fibroids are larger than 3 cm.
- It only treats the **endometrial lining** and does not address the underlying pathology of large, multiple **intramural fibroids**.
*Gonadotrophin-releasing hormone analogues*
- **GnRH analogues** are typically used for **short-term** management (usually <6 months) to shrink fibroids before surgery or to treat anemia.
- Symptoms recur rapidly after discontinuation, and long-term use is restricted due to risks of **bone mineral density loss** and menopausal side effects.
*Levonorgestrel intrauterine system*
- The **LNG-IUS** is less likely to be effective or stay in place (increased risk of **expulsion**) when the uterine cavity is significantly distorted by large fibroids.
- A **16-week size uterus** and irregular contour suggest a degree of cavity distortion that limits the utility of this hormonal treatment.
*Ulipristal acetate*
- **Ulipristal acetate**, a selective progesterone receptor modulator, has significant restrictions due to concerns regarding **rare but serious liver toxicity**.
- It is no longer considered a first-line long-term management strategy for fibroids and requires rigorous **liver function monitoring** if used.
Question 107: A 26-year-old woman is being monitored for an ectopic pregnancy with expectant management. Her initial beta-hCG was 450 IU/L. At day 4, it has risen to 520 IU/L. At day 7, it is 480 IU/L. She remains asymptomatic and haemodynamically stable. Repeat ultrasound shows no significant change in the 12mm adnexal mass and no free fluid. What is the most appropriate management?
A. Continue expectant management with repeat beta-hCG in 7 days (Correct Answer)
B. Immediate laparoscopy
C. Intramuscular methotrexate
D. Uterine curettage to exclude pregnancy of unknown location
E. Admit for observation
Explanation: ***Continue expectant management with repeat beta-hCG in 7 days***- **Expectant management** is appropriate for patients who are **asymptomatic**, hemodynamically stable, and have a low initial **beta-hCG** (<1,000-1,500 IU/L) with a small adnexal mass.- While the levels fluctuated slightly, the **decline from Day 4 to Day 7** suggests the ectopic pregnancy is resolving spontaneously, requiring only continued weekly monitoring.*Immediate laparoscopy*- **Surgical intervention** is indicated for patients who are hemodynamically unstable, have signs of **tubal rupture**, or have a large adnexal mass (>35mm).- This patient is **clinically stable** and asymptomatic, making invasive surgery unnecessary at this stage.*Intramuscular methotrexate*- **Medical management** with methotrexate is usually considered if beta-hCG levels **plateau or rise** significantly during expectant management.- Since her beta-hCG has started to **decrease**, she is likely to resolve without the potential side effects of **folate antagonism**.*Uterine curettage to exclude pregnancy of unknown location*- This procedure is used to differentiate between a **non-viable intrauterine pregnancy** and an ectopic pregnancy when the location is unclear.- An **adnexal mass** has already been identified on ultrasound, confirming the diagnosis of an ectopic pregnancy and making curettage inappropriate.*Admit for observation*- **Inpatient admission** is reserved for patients with increasing pain, suspected rupture, or those unable to comply with **outpatient follow-up**.- This patient remains **hemodynamically stable** and can be safely monitored through serial outpatient **biochemical assessments**.
Question 108: A 35-year-old woman presents with heavy menstrual bleeding. Her periods last 9 days with flooding for the first 4 days. She has dysmenorrhoea requiring regular analgesia. Transvaginal ultrasound shows a bulky uterus measuring 11 cm with heterogeneous myometrium consistent with adenomyosis. She has two children and does not wish for more. She has tried the LNG-IUS but had it removed after 8 months due to persistent irregular bleeding. What is the most appropriate definitive management?
A. Endometrial ablation
B. GnRH analogues for 6 months
C. High-dose progestogens
D. Trial of combined oral contraceptive pill
E. Total hysterectomy with ovarian conservation (Correct Answer)
Explanation: ***Total hysterectomy with ovarian conservation***- **Hysterectomy** is the only **definitive management** for **adenomyosis**, as it completely removes the ectopic endometrial tissue embedded within the **myometrium**.- Since the patient has completed her family, failed **conservative management** (LNG-IUS), and suffers from severe symptoms, this surgical approach provides a permanent cure while maintaining **hormonal function** through ovarian conservation.*Endometrial ablation*- This procedure is often ineffective for **adenomyosis** because it only targets the superficial endometrial lining, leaving deeper **myometrial disease** untreated.- It has a high **failure rate** in women with bulky uteri or extensive adenomyosis, often leading to subsequent need for surgery.*GnRH analogues for 6 months*- These provide only a **temporary solution** by inducing a hypoestrogenic state and are generally used as a bridge to surgery rather than definitive treatment.- Use is limited to 6 months due to risks of **bone mineral density loss** and vasomotor symptoms, and symptoms typically recur once treatment stops.*High-dose progestogens*- These are unlikely to succeed given that the **LNG-IUS**, which provides a high local dose of progestogen, has already failed to control the **irregular bleeding** and pain.- Side effects of systemic high-dose progestogens, such as weight gain and mood changes, often result in poor **patient compliance**.*Trial of combined oral contraceptive pill*- The **combined oral contraceptive pill** is considered a first-line medical therapy but is frequently insufficient for the severe **dysmenorrhea** and flooding associated with structural adenomyosis.- Given the failure of the more potent **LNG-IUS**, a trial of COCP is unlikely to provide the definitive relief requested by a patient with significant quality-of-life impairment.
Question 109: A 40-year-old woman with heavy menstrual bleeding has been using a levonorgestrel intrauterine system for 2 years. She now presents with continuous light bleeding for 6 weeks. She is otherwise well with no abdominal pain. The IUS threads are visible on speculum examination. Bimanual examination is unremarkable. What is the most appropriate initial management?
A. Commence oral tranexamic acid
B. Hysteroscopy and endometrial biopsy
C. Reassure and review in 3 months
D. Remove the IUS and insert a new one
E. Transvaginal ultrasound to check IUS position (Correct Answer)
Explanation: ***Transvaginal ultrasound to check IUS position*** - A **sudden change** in bleeding pattern after 2 years of stability in a patient with a **Levonorgestrel-IUS** warrants investigation to exclude **malposition** or structural pathology. - The **transvaginal ultrasound (TVUS)** is the most appropriate initial tool to confirm the device is correctly located within the uterine cavity and to assess the **endometrial profile**. *Commence oral tranexamic acid* - **Tranexamic acid** is used for heavy bleeding, not typically for the **light, continuous spotting** described in this scenario. - Medical management of symptoms without investigating the **underlying cause** of a new bleeding pattern is inappropriate. *Hysteroscopy and endometrial biopsy* - While used to exclude **endometrial pathology**, these are more invasive and typically reserved for when initial imaging is inconclusive or if the patient is at high risk for **malignancy**. - In a 40-year-old with an IUS already in place, confirming **device position** via ultrasound is the standard first-line step. *Reassure and review in 3 months* - **Reassurance** is only appropriate in the first 6 months after insertion when **irregular spotting** is a common and expected side effect. - A new onset of continuous bleeding after being **established on the IUS** for 2 years requires active investigation rather than watchful waiting. *Remove the IUS and insert a new one* - Removal is premature without first confirming the current device's **position** or identifying the cause of the bleeding. - If the IUS is located correctly, simply replacing it is unlikely to resolve the issue and may expose the patient to unnecessary **procedural risks**.
Question 110: A 24-year-old woman presents to the emergency department with 6 weeks amenorrhoea, right-sided pelvic pain, and vaginal spotting. She has a copper IUD in situ. Vital signs show blood pressure 105/65 mmHg, heart rate 92 bpm, temperature 37.1°C. Abdominal examination reveals right iliac fossa tenderness without guarding. Pregnancy test is positive. Transvaginal ultrasound shows an empty uterus, 25mm right adnexal mass, and minimal free fluid in the pouch of Douglas. Serum beta-hCG is 2100 IU/L. What is the most appropriate immediate management?
A. Admit for observation and repeat beta-hCG in 48 hours
B. Arrange laparoscopy for ectopic pregnancy (Correct Answer)
C. Intramuscular methotrexate and remove IUD
D. Remove IUD and arrange outpatient follow-up
E. Remove IUD and commence methotrexate
Explanation: ***Arrange laparoscopy for ectopic pregnancy*** - Surgical intervention via **laparoscopy** is the most appropriate immediate management due to the patient's symptomatic presentation (pelvic pain, spotting), a **positive beta-hCG** (2100 IU/L), an **adnexal mass** (25mm), and **minimal free fluid** in the pouch of Douglas, all highly suggestive of an unruptured or potentially rupturing ectopic pregnancy. - The presence of a **copper IUD** in situ is also a relative contraindication to medical management with methotrexate and increases the risk of ectopic pregnancy, making surgical removal of the ectopic gestation the most definitive and safest option to prevent **tubal rupture** and **hemorrhage**.*Admit for observation and repeat beta-hCG in 48 hours* - **Expectant management** or observation is generally reserved for hemodynamically stable patients with very low or declining **beta-hCG levels** (<1000 IU/L) and no evidence of rupture or significant adnexal mass. - This patient's **beta-hCG of 2100 IU/L**, combined with significant symptoms and ultrasound findings, indicates an active and potentially unstable ectopic pregnancy, making observation risky.*Intramuscular methotrexate and remove IUD* - **Methotrexate** is contraindicated or has a higher failure rate in the presence of an **IUD**, and its effectiveness is reduced with **beta-hCG levels >1500-2000 IU/L** or the presence of significant free fluid. - The patient's **pelvic pain** and **free fluid** suggest possible ongoing rupture or impending rupture, which are absolute contraindications for medical management.*Remove IUD and arrange outpatient follow-up* - Removing the IUD alone does not resolve the **ectopic pregnancy**, and arranging outpatient follow-up for a patient with symptomatic ectopic pregnancy puts them at extremely high risk for **tubal rupture** and **life-threatening hemorrhage**. - This approach is medically unsafe and would delay crucial definitive treatment for a potentially unstable condition.*Remove IUD and commence methotrexate* - While removing the IUD might be considered, initiating **methotrexate** is still problematic due to the **high beta-hCG (2100 IU/L)**, the presence of an **adnexal mass**, and clinical symptoms suggesting an active ectopic. - **Surgical management** is preferred when the diagnosis of ectopic pregnancy is clear, the patient is symptomatic, and there are ultrasound findings such as an adnexal mass, to ensure definitive treatment and prevent complications.
