Topic module

Postoperative Assessment and Diagnosis

Assess immediate, short- and long-term postoperative deterioration.

Long-form learning
Concept to Risk to Memory to Check-up

How to prepare for MRCOG Part 2

Build a complete clinical map, then rehearse diagnosis, test selection and interpretation, management, prognosis and patient-centred safety in current UK practice.

Core concepts

Concept 1

Structured assessment, timing of complications, observations, fluid balance, laboratory tests, imaging and differential diagnosis.

Exam cue: Identify the clinical domain and exact task before reviewing the option list.

Concept 2

Use operation type, postoperative day, physiology and trends to identify the most likely and most dangerous cause.

Exam cue: Use gestation, urgency, trend, prior treatment and patient preference to rank plausible answers.

Concept 3

Stabilise airway, breathing and circulation and escalate suspected haemorrhage, sepsis, thromboembolism or organ injury.

Exam cue: Choose the safest proportionate action for the stated point in care and know when multidisciplinary escalation is required.

Concept 4

Use current UK obstetric and gynaecological guidance while integrating diagnosis, investigations, management and epidemiology.

Risk pitfalls and guardrails

Attributing deterioration to normal recovery or one abnormal result without the operation, timeline and complete assessment.

Guardrail: Do not choose a possible diagnosis or later definitive intervention when the question asks for the single best answer at this exact point in care.

Choosing a theoretically possible answer rather than the single best option at this point in the pathway.

Guardrail: Do not choose a possible diagnosis or later definitive intervention when the question asks for the single best answer at this exact point in care.

Inventing a paper-specific or Knowledge Area weighting that RCOG has not published.

Guardrail: Only the 40% SBA and 60% EMQ mark split is official; RCOG publishes no numerical Knowledge Area or paper-specific allocation.

Memory anchors

Postoperative Assessment and Diagnosis: scope

Structured assessment, timing of complications, observations, fluid balance, laboratory tests, imaging and differential diagnosis.

Postoperative Assessment and Diagnosis: clinical reasoning

Use operation type, postoperative day, physiology and trends to identify the most likely and most dangerous cause.

Postoperative Assessment and Diagnosis: safety boundary

Stabilise airway, breathing and circulation and escalate suspected haemorrhage, sepsis, thromboembolism or organ injury.

Postoperative Assessment and Diagnosis: common trap

Attributing deterioration to normal recovery or one abnormal result without the operation, timeline and complete assessment.

Postoperative Assessment and Diagnosis: Part 2 sequence

Define the diagnosis or decision, select and interpret the investigation, compare management options, then check epidemiology, prognosis and patient-centred safety.

Checkpoint rule

Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.

Knowledge Check (after reading)

Short check-up to confirm understanding of this module.

Check-up Questions

1-2 question checkpoint

On the first day after hysterectomy, a patient is tachycardic and hypotensive with increasing abdominal girth and falling urine output. The wound is dry. What is the most likely cause?

Five days after pelvic surgery, a patient develops pleuritic chest pain, tachycardia and unexplained hypoxaemia. What diagnosis should be prioritised?

Answer all questions to submit.
