Abdominal Examination Routine — The DCE Short-Case Systematic Approach
Also known as abdominal examination · abdominal exam · abdomen examination · examine the abdomen · abdominal physical examination · per abdominal examination · gastrointestinal examination · hepatomegaly examination · splenomegaly examination · organomegaly differentiation · ascites examination · shifting dullness · fluid thrill · spider naevi · palmar erythema · caput medusae · Kayser-Fleischer ring · Virchow node · Troisier sign · Dupuytren contracture · expansile pulsation
Consultant-physician-depth guide to the systematic abdominal examination for the DCE short case and MRCP PACES. Covers the reproducible head-to-toe twelve-step routine, the key physical signs and their interpretation (clubbing, palmar erythema, Dupuytren contracture, spider naevi, scleral icterus, Kayser-Fleischer rings, Virchow node, caput medusae), the differentiation of organomegaly (liver versus spleen versus kidney by direction, percussion, ballotability and surface), the evidence-based examination of ascites (shifting dullness, fluid thrill), the abdominal aortic aneurysm (expansile pulsation), the signs of peritonitis, the standard oral presentation template, and the discussion questions the examiner will ask. Structured for FRACP DCE and MRCP PACES. Every sign is referenced to the JAMA Rational Clinical Examination series.

Red flags
- An abdomen that is rigid, silent and with the patient motionless is peritonitis until proven otherwise — this is a surgical emergency requiring urgent senior surgical review and cross-sectional imaging
- An expansile pulsatile epigastric mass in a man over 65 is a ruptured abdominal aortic aneurysm until proven otherwise — do not palpate firmly, do not delay, call the vascular surgeon immediately
- Visible peristalsis with a tympanic distended abdomen and tinkling bowel sounds is bowel obstruction — the patient needs nasogastric decompression, intravenous fluids and urgent surgical assessment
- A patient who cannot lie flat for the abdominal examination because of pain has peritonism — respect the posture, it is a diagnostic sign, and do not force them supine
- Cachexia with a palpable irregular hard liver edge is metastatic malignancy until proven otherwise — the examination must include a careful search for a primary
- New onset massive ascites with no stigmata of chronic liver disease raises ovarian malignancy (Meigs syndrome), Budd-Chiari syndrome, or peritoneal carcinomatosis — do not assume cirrhosis
Abdominal Examination Routine — The DCE Short-Case Systematic Approach
The answer first
The abdominal examination is the classic DCE short case — it appears in every FRACP DCE cycle and is a mandatory station in MRCP PACES (Station 3). The instruction is always the same: "Please examine this patient's abdomen." The candidate who performs a fluent, complete, reproducible head-to-toe routine, presents the findings in a structured two-minute presentation, and discusses the interpretation of each sign with confidence will pass. The candidate who auscultates after palpation, who cannot differentiate a spleen from a kidney, or who omits the hands, face and neck has already failed, regardless of what they find in the abdomen itself. [1]
The reproducible sequence is a twelve-step head-to-toe routine that examines the abdomen in the context of the whole patient, because the abdomen is the target organ for systemic diseases — chronic liver disease, inflammatory bowel disease, malignancy, nephrotic syndrome, endocrine disease, and infection all leave signs in the hands, face, chest and legs long before they are palpable in the abdomen. The candidate who examines only the abdomen misses half the marks. [1]
The single most important departure from other system examinations is that you auscultate before you palpate. In the cardiovascular and respiratory examinations, you inspect, palpate, percuss then auscultate. In the abdominal examination, you inspect, auscultate, then palpate and percuss — because palpation and percussion can stimulate or alter bowel sounds, destroying the very information you are trying to collect. Every examiner watches for this, and the candidate who palpates first has demonstrated that they do not understand why the sequence differs. [1]
The second non-negotiable principle is start palpation away from the site of pain. If the patient reports right iliac fossa pain, you begin in the left iliac fossa and work systematically toward the painful area. This builds trust, allows the patient to relax, and gives you a baseline of what their non-tender abdomen feels like before you reach the tender region. [1]
DCE high-yield: The three most commonly tested abdominal short-case scenarios are (1) chronic liver disease with its constellation of stigmata — spider naevi, palmar erythema, Dupuytren contracture, gynaecomastia, ascites, and hepatosplenomegaly; (2) organomegaly — the candidate who can differentiate liver, spleen and kidney at the bedside passes; and (3) the acute abdomen — guarding, rigidity, rebound tenderness, and the differentiation of surgical from medical causes.
