Gynaecology Examination - Structured Model Answers

Reference: Berek & Novak's Gynecology, Shaw's Textbook of Gynaecology, Dutta's Textbook of Gynaecology

CASE IV - Mrs. Khadka, 58-year-old Postmenopausal Woman with Bleeding Per Vaginum


Q.16 - Possible Causes of Bleeding Per Vaginum in a 58-year-old Postmenopausal Woman [6 marks]

Postmenopausal bleeding (PMB) is defined as bleeding occurring more than 12 months after the last menstrual period. It is significant in 10% of cases due to carcinoma.
A. Uterine Causes (Most Common)
CauseNotes
Endometrial carcinomaMost feared cause; accounts for ~10% of PMB
Endometrial hyperplasiaSimple, complex, or atypical
Endometrial polypBenign; common cause of PMB
Hormone Replacement Therapy (HRT)Iatrogenic bleeding
Endometrial atrophyMost common benign cause
B. Cervical Causes
  • Cervical carcinoma
  • Cervical polyp
  • Cervicitis / cervical ectropion
C. Vaginal Causes
  • Atrophic vaginitis (post-menopausal estrogen deficiency)
  • Vaginal carcinoma (rare)
D. Ovarian Causes
  • Functioning (estrogen-secreting) ovarian tumors - e.g., granulosa cell tumor
E. Extragenital Causes
  • Urethral caruncle
  • Rectal/urinary tract bleeding (mistaken as vaginal)
  • Anticoagulant therapy
F. Systemic Causes
  • Blood dyscrasias (thrombocytopenia, von Willebrand disease)
  • Liver disease (coagulopathy)
Note: The rule of thumb - "Any postmenopausal bleeding is carcinoma until proved otherwise." - Berek & Novak's Gynecology

Q.17 - Investigation for Further Evaluation of Postmenopausal Bleeding [5 marks]

Per speculum examination revealed healthy cervix, normal vaginal walls, and normal fornices - so the source is most likely intrauterine. Investigations proceed in a systematic manner:
A. First-Line (Essential) Investigations
  1. Transvaginal Ultrasonography (TVS)
    • Investigation of choice for PMB
    • Endometrial thickness (ET):
      • ET < 4-5 mm: cancer unlikely (NPV ~99%)
      • ET ≥ 5 mm: requires further evaluation by biopsy
      • In this case (Case II): ET = 32 mm - highly suspicious for malignancy
  2. Endometrial Sampling / Biopsy
    • Pipelle endometrial biopsy (OPD procedure) - first choice
    • Sensitivity ~90% for endometrial carcinoma
    • Fractional curettage (D&C) if office biopsy inconclusive
  3. Pap Smear / Cervical Cytology
    • To rule out cervical pathology
B. Second-Line Investigations
  1. Hysteroscopy + Directed Biopsy - Gold standard for intrauterine pathology; allows direct visualization
  2. Sonohysterography (saline infusion sonography) - Defines intrauterine lesions (polyps, submucous fibroids) more precisely
C. General / Systemic Investigations
  1. Complete blood count, coagulation profile (PT, aPTT)
  2. LFT, RFT
  3. Serum CA-125 (if malignancy suspected - elevated in 80% advanced cases)
  4. Blood sugar (screen for diabetes - associated risk factor)
D. Pre-surgical Workup (if malignancy confirmed)
  1. Chest X-ray (pulmonary metastasis)
  2. MRI pelvis - best imaging for myometrial invasion depth and cervical involvement
  3. CT abdomen/pelvis - lymph node assessment, distant metastasis
  4. ECG + cardiac evaluation
"An endometrial thickness of less than 5 mm measured by transvaginal ultrasonography is unlikely to indicate endometrial cancer." - Berek & Novak's Gynecology

Q.18 - Risk Factors for Endometrial Carcinoma [6 marks]

Most risk factors relate to prolonged, unopposed estrogen stimulation of the endometrium (Type I, estrogen-dependent endometrioid carcinoma - the majority).
Table: Risk Factors for Endometrial Cancer (Berek & Novak's Gynecology, Table 37-1)
Risk FactorRelative Risk
Nulliparity2-3
Late menopause (after age 52)2.4
Obesity: 21-50 lbs overweight3
Obesity: >50 lbs overweight10
Diabetes mellitus2.8
Unopposed estrogen therapy4-8
Tamoxifen therapy2-3
Atypical endometrial hyperplasia / EIN8-29
Lynch II syndrome (HNPCC)20
Explained Mechanisms:
  1. Obesity - Excess peripheral aromatization of androstenedione to estrone in adipose tissue leads to unopposed estrogen stimulation
  2. Nulliparity / Infertility / Anovulation - Chronic exposure to estrogen without progesterone opposition (e.g., PCOS)
  3. Late menopause - Prolonged estrogenic stimulation
  4. Unopposed exogenous estrogen - HRT without progestogen; risk increases with dose and duration; reduced to baseline with 10+ days of progestin
  5. Tamoxifen use - Partial estrogen agonist effect on endometrium
  6. Atypical hyperplasia / EIN - Direct precancerous precursor; 40-50% have concurrent carcinoma
  7. Lynch II syndrome (HNPCC) - Germline mutations in mismatch repair genes (MLH1, MSH2, MSH6); 40-60% lifetime risk
  8. Polycystic Ovary Syndrome (PCOS) - Chronic anovulation, prolonged unopposed estrogen
  9. Functioning ovarian tumors - Estrogen-secreting (granulosa cell tumor)
  10. Diabetes mellitus - Independent risk even after adjusting for obesity
  11. Hypertension - Associated (mechanism unclear)
Protective Factors:
  • Oral contraceptive pill use (50% risk reduction)
  • Multiparity
  • Smoking (increases estrogen metabolism - controversial protective effect)
  • Physical activity

Q.19 - Staging of Endometrial Carcinoma [8 marks]

Endometrial carcinoma is staged surgically and pathologically according to the FIGO (International Federation of Gynecology and Obstetrics) staging system - revised 2009 (and updated 2023).
Staging is surgical - based on operative findings and histopathological examination of the specimen.
FIGO 2009 Surgical Staging of Endometrial Carcinoma
StageDescription
Stage ITumor confined to the corpus uteri
IANo or less than half myometrial invasion (<50%)
IBInvasion equal to or more than half of the myometrium (≥50%)
Stage IITumor invades cervical stroma but does not extend beyond the uterus
Stage IIILocal and/or regional spread of the tumor
IIIATumor invades serosa of corpus uteri and/or adnexae
IIIBVaginal and/or parametrial involvement
IIICMetastasis to pelvic and/or para-aortic lymph nodes
IIIC1Positive pelvic nodes only
IIIC2Positive para-aortic lymph nodes (with or without pelvic nodes)
Stage IVTumor invades bladder and/or bowel mucosa, and/or distant metastasis
IVATumor invasion of bladder and/or bowel mucosa
IVBDistant metastasis including intra-abdominal metastases and/or inguinal lymph nodes
Histological Grading (FIGO):
  • Grade 1: Well differentiated; ≤5% non-squamous, non-morular solid growth pattern
  • Grade 2: Moderately differentiated; 6-50% solid growth
  • Grade 3: Poorly differentiated; >50% solid growth pattern
Key Changes in FIGO 2009 vs. 1988:
  1. Former stages IA and IB were combined into new IA
  2. Endocervical glandular involvement (former stage IIA) eliminated - now considered Stage I
  3. Positive peritoneal cytology no longer upstages disease (though still reported)
  4. Stage IIIC divided into IIIC1 (pelvic nodes) and IIIC2 (para-aortic nodes)
Surgical Staging Procedure includes:
  1. Peritoneal washings/cytology on entering abdomen
  2. Total abdominal hysterectomy + bilateral salpingo-oophorectomy (TAH + BSO)
  3. Inspection and palpation of all peritoneal surfaces
  4. Pelvic and para-aortic lymph node assessment (dissection or sentinel node biopsy)
  5. Omentectomy + peritoneal biopsies in non-endometrioid (Type II) tumors

CASE II - Mrs. X, 45-year-old Perimenopausal Woman with Menorrhagia + Bulky Uterus


Q.7 - Possible Differential Diagnosis [5 marks]

A 45-year-old perimenopausal woman with menorrhagia, abdominal heaviness, and bulky uterus on examination:
A. Structural Causes (PALM - from PALM-COEIN)
  1. Uterine Leiomyoma (Fibroids) - Most common; submucous fibroids cause heavy bleeding; intramural fibroids cause bulk symptoms. Top differential.
  2. Adenomyosis - Diffuse uterine enlargement, dysmenorrhea, menorrhagia in perimenopausal women
  3. Endometrial Polyp - May cause heavy/irregular bleeding
  4. Endometrial Hyperplasia - Especially atypical/EIN at this age
  5. Endometrial Carcinoma - Must be excluded given age, perimenopausal status, and ET of 32 mm on USG
  6. Uterine Sarcoma - Leiomyosarcoma (rapidly enlarging uterus); endometrial stromal sarcoma
B. Non-structural Causes (COEIN)
  1. Anovulatory DUB (Dysfunctional Uterine Bleeding) - Common in perimenopausal state due to declining ovarian function
  2. Coagulation disorders - von Willebrand disease
  3. Iatrogenic - Anticoagulants, antiplatelet therapy
Given the additional finding of ET 32 mm and biopsy showing high-grade adenocarcinoma, the definitive diagnosis in this case is endometrial carcinoma.

Q.8 - Investigations for Definite Diagnosis [8 marks]

A systematic approach:
A. Imaging
  1. Transvaginal Ultrasonography (TVS)
    • First-line investigation
    • Endometrial thickness, uterine size, myometrial invasion, adnexa
    • ET 32 mm in this case is highly abnormal (normal postmenopausal ET <4-5 mm)
    • Assess for submucous fibroids, polyps, vascularity (Doppler)
  2. Sonohysterography (SIS) - Saline infusion: better delineation of intracavitary lesions
  3. MRI Pelvis (Investigation of choice for staging)
    • Depth of myometrial invasion (most accurate: 85-92%)
    • Cervical stromal involvement
    • Parametrial extension
    • Lymph node assessment
  4. CT Abdomen and Pelvis
    • Lymph node metastasis, peritoneal deposits, distant metastasis
    • Less accurate than MRI for local staging
B. Tissue Diagnosis (Essential for Definitive Diagnosis)
  1. Endometrial Biopsy (Pipelle biopsy)
    • OPD procedure, first-line tissue sampling
    • Sensitivity ~90% for endometrial carcinoma
  2. Hysteroscopy + Directed Biopsy - Gold standard
    • Direct visualization of endometrial cavity
    • Targeted biopsy of suspicious areas
    • Also defines associated polyps, fibroids
  3. Fractional Curettage (D&C)
    • Separate curettage of endocervix and endometrium
    • Determines cervical involvement (Stage II disease)
    • Done if office biopsy inadequate or inconclusive
C. Laboratory Tests
  1. Complete blood count - assess anaemia (chronic blood loss)
  2. Coagulation profile
  3. Liver and renal function tests
  4. Blood sugar (diabetes risk factor screening)
  5. Serum CA-125 - elevated in 78-80% of advanced/metastatic endometrial cancer; useful as tumor marker
D. Preoperative Workup
  1. Chest X-ray - pulmonary metastasis
  2. ECG + cardiac evaluation

Q.9 - Risk Factors for Endometrial Carcinoma (High-Grade Adenocarcinoma) [4 marks]

(See Q.18 above for comprehensive list - applicable to both cases)
Summary - Key Risk Factors:
Estrogen-Related (Type I - Endometrioid):
  • Unopposed estrogen exposure (exogenous HRT without progesterone)
  • Obesity (peripheral aromatization)
  • Nulliparity / infertility / anovulation (PCOS)
  • Late menopause (>52 years)
  • Diabetes mellitus
  • Tamoxifen use
  • Atypical endometrial hyperplasia / EIN (RR: 8-29)
  • Functioning ovarian tumors (granulosa cell tumor)
Non-Estrogen-Related (Type II - Serous/Clear Cell):
  • Lynch II syndrome / HNPCC (RR: 20) - MLH1, MSH2, MSH6 mutations
  • Older age (typically presents in postmenopausal women, type II)
  • Prior pelvic radiation
"Obesity, PCOS, tamoxifen use, and unopposed estrogen use are all associated with increased risk of endometrial cancer. Other associated findings include late onset of menopause, nulliparity, diabetes mellitus, and hypertension." - Berek & Novak's Gynecology

Q.10 - Stage-wise Management of Endometrial Carcinoma [8 marks]

Management is primarily surgical for all stages where feasible, with adjuvant therapy based on surgical-pathological staging.
Stage I - Tumor confined to uterus
  • Surgery: Total abdominal hysterectomy + bilateral salpingo-oophorectomy (TAH + BSO) + surgical staging (peritoneal washings, pelvic/para-aortic lymph node assessment)
  • Sentinel lymph node biopsy is increasingly used
  • Stage IA, Grade 1-2: Surgery alone; vaginal brachytherapy may be added
  • Stage IA, Grade 3 / Stage IB (any grade): Surgery + adjuvant vaginal brachytherapy OR external beam radiotherapy (EBRT) based on risk stratification
  • High-risk histology (serous, clear cell): Surgery + chemotherapy (carboplatin + paclitaxel) ± radiotherapy
Stage II - Cervical stromal involvement
  • Surgery: Radical/modified radical hysterectomy (Wertheim's type) + BSO + pelvic lymph node dissection is preferred if feasible
  • Alternatively: TAH + BSO + EBRT to pelvis + vaginal brachytherapy
  • Adjuvant chemotherapy for high-grade tumors
Stage III - Regional spread
  • Stage IIIA (serosa/adnexa): Surgery (cytoreduction) + EBRT + chemotherapy
  • Stage IIIB (vagina/parametrium): Surgery (if operable) + EBRT + brachytherapy + chemotherapy
  • Stage IIIC1 (pelvic nodes+): Surgery + EBRT to pelvis + chemotherapy (carboplatin + paclitaxel)
  • Stage IIIC2 (para-aortic nodes+): Surgery + extended-field RT (pelvis + para-aortic) + chemotherapy
Stage IV - Distant spread
  • Stage IVA (bladder/bowel involvement): Primary radiotherapy (EBRT + brachytherapy) + chemotherapy; surgery if feasible for palliation/cytoreduction
  • Stage IVB (distant metastasis):
    • Systemic chemotherapy: Carboplatin + Paclitaxel (first-line; standard of care)
    • Hormonal therapy: Medroxyprogesterone acetate (MPA) or megestrol acetate for grade 1-2 endometrioid, ER/PR-positive tumors
    • Targeted therapy: Pembrolizumab (anti-PD-1) + lenvatinib (for mismatch repair-proficient tumors)
    • Trastuzumab for HER2-positive serous carcinoma
    • Palliative radiotherapy for bone/CNS metastasis

Obstetrics Examination - Structured Model Answers

Reference: DC Dutta's Textbook of Obstetrics (9th ed.), Williams Obstetrics (25th ed.), Creasy & Resnik's Maternal-Fetal Medicine

CASE I - Mrs. G2P1L1, 18 yrs, 41 weeks, Referred in Active Labor - Unable to Deliver for 2 Hours


Q.1 - How will you approach her? Write in terms of History and Examination Findings [5 marks]

Approach: This is an obstetric emergency. Rapid assessment and simultaneous resuscitation are mandatory.

A. History

Presenting Complaint:
  • Duration and character of labor pains
  • Duration of membrane rupture (SROM/AROM)
  • Time of full cervical dilatation (confirmed at referring centre)
  • Duration of inability to deliver (2 hours at full dilatation = prolonged second stage)
Obstetric History:
  • G2P1L1 - details of previous delivery (vaginal/LSCS, any complications)
  • Previous baby's weight, mode of delivery, any disproportion
  • Current pregnancy: ANC attended or not, USG reports (estimated fetal weight, lie, presentation)
Referral Details:
  • Reason for referral (failure to deliver despite full dilatation)
  • Any medications/interventions given at the referring centre (oxytocin, misoprostol, vacuum/forceps attempted)
  • Time taken to reach this centre (4 hours - prolonged transit)
Review of Systems:
  • Bleeding per vaginum
  • Fetal movements felt or not
  • Urinary output (indicator of hydration status)

B. Examination Findings

General Examination:
  • Conscious level, orientation
  • Pallor, dehydration, icterus, oedema
  • Pulse rate, blood pressure, respiratory rate, temperature
Abdominal Examination:
  • Fundal height and lie of fetus
  • Fetal presentation and engagement
  • Uterine contour - whether well-defined or obliterated
  • Retraction ring (Bandl's ring) - a transverse groove between upper and lower uterine segments at or above the umbilicus (pathognomonic of obstructed labor)
  • Uterine tenderness - between or during contractions
  • Frequency, duration, and strength of uterine contractions
  • Fetal Heart Sounds (FHS) - rate, rhythm, presence/absence
Per Vaginal Examination (under aseptic conditions):
  • Cervical dilatation and effacement
  • Station of presenting part
  • Presence of caput succedaneum and moulding (degree: 0, +1, +2, +3)
  • Position of fetal head (asynclitism)
  • Colour of liquor - clear, meconium-stained, or absent (dry vagina suggests prolonged rupture of membranes)
  • Pelvic assessment - adequacy of pelvis

Q.2 - What is the Likely Diagnosis? [2 marks]

Based on the clinical findings given:
  • BP 80/40 mmHg, Pulse 110/min (shock)
  • Uterine contour not defined, FHS not localized
  • Vagina dry and hot, Head station high
  • Unable to deliver for 2 hours after full dilatation
  • 4-hour transit delay after referral
Diagnosis: Ruptured Uterus (most likely complete rupture of the lower uterine segment)
Supporting Features:
FeatureSignificance
BP 80/40, Pulse 110Hypovolaemic/haemorrhagic shock
Uterine contour undefinedFetus partly/fully extruded into abdominal cavity
FHS not localizedFetal distress / intrauterine fetal death
Dry, hot vaginaProlonged rupture of membranes with sepsis
High head stationPresenting part has receded from pelvis after rupture
Pale patientIntraabdominal haemorrhage
"The classical picture of complete uterine rupture: sudden cessation of uterine contractions, severe abdominal pain, signs of haemorrhagic shock, recession of presenting part, inability to palpate FHS." - DC Dutta's Obstetrics
Differential Diagnosis:
  • Impending rupture (Bandl's ring visible/palpable)
  • Concealed abruption placentae
  • Severe obstructed labor with fetal distress

Q.3 - Write the Management Plan for Her [4 marks]

Immediate resuscitation and emergency surgery (simultaneously):

Step 1: Resuscitation (A-B-C)

  1. Airway - ensure patent airway; give high-flow oxygen (10-15 L/min by mask)
  2. IV access - two large-bore IV cannulae (16G or 18G)
  3. IV fluids - rapid infusion of crystalloids (Normal saline / Ringer's lactate): 1-2 litres stat
  4. Blood - send for cross-matching; arrange 4-6 units packed red blood cells urgently
  5. Catheterize - Foley's catheter; monitor urine output (target >30 mL/hr)
  6. Blood tests - CBC, coagulation profile, blood group and type, RFT, LFT, blood culture
  7. NPO - nil by mouth; call anaesthesiologist

Step 2: Informed Consent

  • Explain the emergency situation to patient/relatives
  • Consent for emergency laparotomy, hysterectomy if required, blood transfusion, sterilization

Step 3: Emergency Laparotomy (Definitive Treatment)

  • Midline vertical incision under general anaesthesia
  • Deliver the baby and placenta from abdominal cavity
  • Assess rupture site: location, extent, edges (clean vs. ragged), involvement of bladder or broad ligament
Surgical Options based on operative findings:
FindingProcedure
Clean, linear, limited rupture (lower segment)Repair (uterine conservation) + bilateral tubal ligation
Extensive, irregular rupture, uncontrollable bleedingSubtotal/Total hysterectomy
Lateral extension involving broad ligament, ureterTotal hysterectomy
Bladder involvementBladder repair + urology consultation
  • This case: 8 cm rupture in lower uterine segment - repair was done (as described) - appropriate if edges were viable and hemostasis achieved

Step 4: Antibiotics

  • Broad-spectrum IV antibiotics (ampicillin + gentamicin + metronidazole) - given dry/hot vagina suggests infection

Step 5: Postoperative (see Q.4)


Q.4 - What Special Care will you take in the Postoperative Period? [3 marks]

A. Monitoring

  1. Vital signs - pulse, BP, respiratory rate, temperature - every 15 min initially, then hourly
  2. Urine output - hourly via Foley's catheter; target >30 mL/hr; oliguria suggests ongoing haemorrhage or renal failure
  3. Abdominal drain output - note colour, amount (haemorrhage vs. serous)
  4. Haemoglobin/haematocrit - check 6-hourly until stable; transfuse if Hb <7-8 g/dL

B. IV Fluids and Transfusion

  • Maintain IV crystalloids until oral intake established
  • Blood transfusion as indicated (target Hb >10 g/dL post-surgery in haemorrhagic shock)
  • Fresh Frozen Plasma (FFP) and platelets if DIC features present

C. Antibiotics

  • Continue broad-spectrum IV antibiotics for 5-7 days (ampicillin + gentamicin + metronidazole)
  • Step down to oral antibiotics when clinically stable

D. Pain Management

  • Adequate analgesia (IV morphine/pethidine or PCA initially, then NSAIDs)

E. Respiratory Care

  • Deep breathing exercises, incentive spirometry to prevent atelectasis
  • Ambulation when stable (Day 1-2 post-op)

F. DVT Prophylaxis

  • LMWH (enoxaparin 40 mg SC once daily) once haemostasis is secure
  • Compression stockings, early mobilisation

G. Nutritional Support

  • IV fluids until bowel sounds return, then oral fluids progressing to full diet
  • High-protein diet for wound healing

H. Psychological Support

  • Counseling - regarding loss of fetus (if IUD), surgical procedure performed
  • Discuss future pregnancy plans and risks

I. Wound Care

  • Daily wound dressing; watch for wound infection, dehiscence

J. Catheter Care

  • Maintain Foley's catheter for at least 7-10 days (especially if bladder was involved in repair)

Q.5 - What are the Immediate and Long-term Complications of Obstructed Labor? [4 marks]

MATERNAL COMPLICATIONS

Immediate / Short-term:
SystemComplication

  • Intracranial haemorrhage (from moulding)
  • Hypoxic ischemic encephalopathy (HIE)
  • Neonatal death
Long-term (in surviving neonates):
  • Cerebral palsy
  • Developmental delay
  • Epilepsy

Q.6 - Write about the Preventive Measures for Obstructed Labor [2 marks]

Prevention operates at three levels - primary, secondary, and tertiary:

A. Primary Prevention (Before Labour)

  1. Adequate antenatal care (ANC) - minimum 4-8 ANC visits to identify high-risk pregnancies
  2. Nutritional support in childhood and adolescence - prevent rickets, stunting, contracted pelvis
  3. Prevention of child marriage - girls married before pelvic maturity are at high risk; legal minimum marriage age
  4. Education of girls - social awareness, empowerment
  5. Pre-pregnancy assessment - identify CPD, malpresentation early
  6. Ultrasound in antenatal period - detect malpresentation, macrosomia, multiple pregnancy
  7. Clinical pelvimetry - detect inadequate pelvis; plan elective LSCS if CPD identified

B. Secondary Prevention (During Labour)

  1. Partograph use - WHO partograph plotting cervical dilatation, descent, uterine contractions; action line and alert line to detect abnormal labour early
  2. Skilled birth attendant at every delivery
  3. Early diagnosis of malpresentation - external cephalic version before labor where appropriate
  4. Timely referral - do NOT allow prolonged labour without progress; refer at alert line
  5. Avoid prolonged trial of labour in CPD
  6. Avoid fundal pressure (Kristeller manoeuvre) - increases risk of rupture

C. Tertiary Prevention

  1. Timely LSCS when labour does not progress
  2. Strengthening referral systems - transport, communication infrastructure
  3. Training of birth attendants - TBAs and ANMs trained to use partograph and refer early
  4. EmOC (Emergency Obstetric Care) services - ensure 24-hour availability at referral centres

CASE II - Mrs. X, G5P4L4, 40 years, 40 weeks, Referred with Labour Pain 3 days, Bearing Down 1 day


Q.5 (Case II) - What is your Probable Diagnosis? [2 marks]

Diagnosis: Obstructed Labor with Impending / Completed Uterine Rupture
Reasoning:
  • Grand multipara (G5P4L4) - uterine wall thinned from repeated pregnancies
  • 3 days of labor pain + 1 day of bearing down = prolonged, neglected labor
  • Dehydrated and disoriented = severe systemic deterioration
  • Foul-smelling discharge = intrauterine infection/sepsis
The clinical picture (Q.7 findings) of:
  • BP 80/50, Pulse 140/min (severe shock)
  • Uterine contour absent, fetal parts easily palpable
  • FHS absent (dead fetus)
  • Dry, edematous vulva + big dry caput + high fetal station
confirms: Ruptured Uterus (complete) with IUFD in a Grand Multipara with Neglected/Obstructed Labour

Q.6 (Case II) - Enlist the Symptoms and Signs of Obstructed Labor [10 marks]

SYMPTOMS

1. Prolonged, Painful Labour
  • Labour pains of unusually long duration (>18 hours primigravida, >12 hours multigravida) without delivery
  • Contractions become more painful, frequent but non-progressive
2. Failure to Progress
  • No descent of presenting part despite good uterine contractions
  • Cervix fully dilated but baby not delivering (prolonged second stage)
3. Passage of Liquor
  • Spontaneous or early rupture of membranes
  • Liquor may be meconium-stained or foul-smelling (infected)
4. General Symptoms
  • Severe exhaustion, inability to bear pain
  • Nausea, vomiting (from dehydration and ketosis)
  • Cessation of urination (dehydration + urinary retention)
  • If rupture occurs: sudden severe tearing abdominal pain, then relief of contractions

SIGNS

General Signs:
SignSignificance
DehydrationDry tongue, sunken eyes, poor skin turgor
KetosisAcetone on breath
PyrexiaTemperature >38°C (chorioamnionitis/sepsis)
Tachycardia (Pulse >100)Dehydration, sepsis, or haemorrhage
HypotensionShock - haemorrhagic or septicaemic
Disorientation/confusionSevere sepsis, shock
AnaemiaChronic blood loss
Abdominal Signs:
SignSignificance
Uterus - tense, tenderProlonged contractions, peritonitis
Bandl's Retraction RingTransverse groove at/above umbilicus between upper and lower segments; rises with progression; PATHOGNOMONIC of obstructed labor
Round ligaments taut and visibleBilateral tense round ligaments = impending rupture
Fetal parts easily palpableFetus partially/fully in abdominal cavity - rupture
Uterine contour lostRupture with extrusion of fetus
FHS absent or irregularFetal distress / IUFD
Lower segment thinned outPalpable through abdominal wall
Distended bladderUrinary retention; bladder displaced and compressed
Per Vaginal Signs:
SignSignificance
Excessive caput succedaneumBig, soft, boggy swelling on presenting part - "soft caput"
Severe moulding (Grade 3: +++)Bones overlapping and non-reducible - CPD
High head stationHead impacted or receded after rupture
Dry, hot vaginaProlonged rupture of membranes, dehydration
Edematous cervical lipsProlonged pressure from presenting part
Meconium/foul-smelling liquorFetal distress / intrauterine infection
Vaginal lacerationsProlonged pressure, attempted delivery
Signs in the Presented Case:
  • BP 80/50, Pulse 140 = severe shock ✓
  • Uterine contour absent, fetal parts palpable = rupture ✓
  • FHS absent = IUFD ✓
  • Dry edematous vulva = prolonged labour + infection ✓
  • Big dry caput + high fetal station = obstructed labour + rupture ✓

Q.7 (Case II) - What is the Most Probable Complication of the Above Condition? [3 marks]

Most Probable Complication: Complete Uterine Rupture
Evidence in this case:
  1. Uterine contour could not be made out
  2. Fetal parts easily palpable (fetus extruded into abdominal cavity)
  3. FHS absent (fetal death from haemorrhage/hypoxia)
  4. BP 80/50, Pulse 140 = haemorrhagic shock
  5. 3 days of obstructed labour in a grand multipara (maximum risk group)
Other important complications already present/anticipated:
  1. Haemorrhagic shock (from intraperitoneal haemorrhage)
  2. Intrauterine fetal death (IUFD) - FHS absent
  3. Septicaemia / Septic shock - foul-smelling discharge + 3 days of obstructed labour
  4. Disseminated Intravascular Coagulation (DIC) - from prolonged shock + dead fetus
  5. Acute Renal Failure (ARF) - prolonged hypoperfusion
  6. Peritonitis - fetus + infected liquor in peritoneal cavity
  7. Multi-organ dysfunction syndrome (MODS) - terminal if untreated

Q.8 (Case II) - How will you Manage this Case? [10 marks]

This is a life-threatening obstetric emergency. Simultaneous resuscitation and preparation for emergency surgery.

STEP 1: IMMEDIATE RESUSCITATION

  1. Call for help - senior obstetrician, anaesthetist, senior nurse, blood bank
  2. Airway and Oxygen - High flow O₂ 10-15 L/min via face mask
  3. IV access - Two large-bore (16G) IV cannulae in both arms
  4. IV Fluids - Ringer's lactate 1-2 litres STAT; second litre running
  5. Blood - Send for urgent cross-match (4-6 units); meanwhile use O-negative blood if collapse
  6. Urinary catheter - Foley's catheter; monitor hourly urine output
  7. Investigations stat:
    • CBC, coagulation (PT, aPTT, fibrinogen), blood group/cross-match
    • Blood culture, urine culture
    • RFT, LFT, blood glucose, electrolytes
    • Serum lactate (severity of shock)
  8. Treat DIC if present - FFP, cryoprecipitate, platelet transfusion as guided by coagulation profile

STEP 2: INFORMED CONSENT

  • Explain diagnosis: ruptured uterus, IUFD, haemorrhagic shock
  • Consent for: emergency laparotomy, hysterectomy, blood transfusion, sterilization (irreversible if uterus removed)

STEP 3: EMERGENCY LAPAROTOMY

Timing: As soon as minimally stabilized (within 30-60 minutes; do NOT delay for full stabilization)
Anaesthesia: General anaesthesia (patient in shock; regional contraindicated)
Incision: Midline vertical subumbilical incision (fastest access)
Operative Findings Anticipated:
  • Haemoperitoneum
  • Fetus ± placenta in peritoneal cavity
  • Rupture site in lower uterine segment / posterior wall
Operative Steps:
  1. Deliver the baby from abdominal cavity (dead fetus in this case)
  2. Deliver placenta - manual removal
  3. Control haemorrhage - clamp bleeding vessels
  4. Assess rupture site - size, location, edges, involvement of bladder/ureters/broad ligament
  5. Decide: Repair vs. Hysterectomy
SituationProcedure
Grandmultipara (as in this case) with complete ruptureSubtotal / Total Hysterectomy (preferred - no future reproductive need implied; definitive haemostasis)
Young woman, first rupture, clean edges, bleeding controlledUterine repair + bilateral tubal ligation
Bladder injuryRepair bladder in layers + urological consultation
Broad ligament haematomaEvacuate + ligate bleeding vessels
In this case (G5P4L4, grand multipara, complete rupture, foul-smelling liquor/sepsis):
  • Subtotal/Total Hysterectomy is the procedure of choice
  • Thorough peritoneal lavage with warm saline
  • Place abdominal drains
  • Close abdomen in layers

STEP 4: POSTOPERATIVE MANAGEMENT

Monitoring:
  • ICU/HDU care - continuous vital sign monitoring
  • Hourly urine output - target >30 mL/hr
  • Abdominal drain output - monitor for ongoing haemorrhage
  • Serial CBC, coagulation studies, RFT every 6-12 hours
Fluids and Blood:
  • IV fluids to maintain euvolemia
  • Blood transfusion to target Hb ≥8-10 g/dL
  • Correct DIC with FFP, cryoprecipitate, platelets as needed
Antibiotics (Critical - given septic case):
  • IV Ampicillin 2g 6-hourly
  • IV Gentamicin 1.5 mg/kg 8-hourly (dose-adjust for renal function)
  • IV Metronidazole 500 mg 8-hourly
  • Continue for 7-10 days; switch to oral after 48-72 hours afebrile
Analgesia:
  • IV opioids (morphine/tramadol) for 24-48 hours, then NSAIDs + paracetamol
DVT Prophylaxis:
  • LMWH when haemostasis confirmed + compression stockings
Nutritional Support:
  • Oral fluids when bowel sounds return (Day 2-3), then soft diet, then normal
  • Consider nasogastric feeding if delayed recovery
Catheter Care:
  • Foley's catheter for 7-14 days (especially if bladder involved)
  • Urine output monitoring; renal function tests
Renal Support:
  • If oliguric/anuric despite adequate fluid: consider furosemide
  • Nephrology consultation if ARF develops
Counselling:
  • Grieve for lost baby - psychological support, counselling services
  • Explain procedure done (hysterectomy) - no future pregnancies possible
  • Reassure about recovery

Expected Outcome: With prompt surgery and resuscitation, maternal mortality in uterine rupture has declined significantly but remains 1-10% in resource-limited settings. Fetal mortality in complete rupture with IUFD is 100% in this case. Early referral and partograph use are the keys to prevention.
