Presenting complaint

“Pain in the upper right side of my tummy for two days.”

History of presenting complaint

Mrs S.A. was well until two days before admission, when she developed pain in the right upper abdomen about one hour after a heavy, fatty evening meal. The pain came on gradually over half an hour, building to a severe, constant ache that she scores 8 out of 10. It radiates to the tip of the right shoulder blade, is worse on deep breathing and on movement, so that she prefers to lie still, and was little relieved by paracetamol. It has not eased at any point over the last 48 hours. She has had nausea throughout and has vomited three times; the vomit contained recently eaten food, with no blood and no bile. She has lost her appetite, and she felt hot yesterday and measured a temperature of 38.4 °C at home, without rigors. Over the previous six months she has had four or five similar but milder attacks, each after a fatty meal, each lasting one to two hours and settling on its own, for which she did not seek medical advice; the present attack differs in being more severe, lasting two days and bringing fever. She has not noticed yellow discolouration of her eyes or skin, dark urine, pale stools or itching. The pain does not pass straight through to the back and is not eased by sitting forward. She has no heartburn, no previous ulcer and no black stools, and she does not take anti-inflammatory painkillers. She has no cough, breathlessness or chest pain on breathing or on exertion, and no burning on passing urine, blood in the urine or loin pain. Her bowels opened normally yesterday, with no change in bowel habit and no weight loss. Her last menstrual period was two weeks ago and her cycles are regular. She has not travelled recently and has had no contact with anyone jaundiced.

Past medical history

No diabetes, hypertension or heart disease. No previous jaundice. Never had an abdominal ultrasound, and has not been told she has gallstones. No blood disorders.

Past surgical history

Two caesarean sections (2012 and 2016), both under spinal anaesthesia with no complications.

Drugs and allergies

Combined oral contraceptive pill for five years. Paracetamol as needed. No anticoagulants, no steroids, no anti-inflammatory drugs.

Allergy: penicillin, which caused a widespread rash.

Family history

Her mother had her gallbladder removed for gallstones. No family history of blood disorders or bowel cancer.

Social history

Lives with her husband and four children. Does not smoke or drink alcohol. Independent in all daily activities. Diet is high in fried food.

Last ate at 14:00 today; last drank water at 19:00.

Abdominal examination

Inspection

Abdomen not distended. It moves with respiration, though movement is reduced in the right upper quadrant. Healed low transverse (Pfannenstiel) scar. No visible masses, pulsation or dilated veins. Hernial orifices intact, with no cough impulse.

Palpation

Marked tenderness with guarding in the right upper quadrant. Murphy's sign positive: she catches her breath on inspiration when the examining hand is under the right costal margin; the same test on the left is negative. No rebound tenderness elsewhere and no generalised rigidity. No palpable gallbladder mass. Liver edge, spleen and kidneys not palpable. No renal angle tenderness.

Percussion

Liver span 11 cm in the mid-clavicular line; liver dullness preserved. No shifting dullness.

Auscultation

Bowel sounds present and normal.

Rectal examination not performed, as not indicated at present.

Other systems

Chest: equal expansion, resonant percussion, normal breath sounds at both bases with no crackles.

Heart: first and second heart sounds normal, no murmurs.

Legs: calves soft and not tender.

Summary

Say this to the examiner Mrs S.A. is a 42-year-old woman with obesity, on the oral contraceptive pill, who presents with two days of constant right upper quadrant pain radiating to the right scapula, with fever and vomiting, on a background of six months of pain after fatty meals. She is not jaundiced. On examination she is febrile and tachycardic, with right upper quadrant tenderness, guarding and a positive Murphy's sign.

Provisional diagnosis

Acute calculous cholecystitis.

Initial plan

  • Nil by mouth, intravenous fluids, analgesia, antiemetic.
  • Bloods: full blood count, C-reactive protein, liver function tests, amylase or lipase, urea and electrolytes, glucose. Pregnancy test.
  • Abdominal ultrasound. ECG and chest X-ray.
  • Intravenous antibiotics, chosen with her penicillin allergy in mind.
  • Discuss with the senior surgeon regarding early laparoscopic cholecystectomy.

Differential diagnosis of right upper quadrant pain

For the OSCE, do not recite a random list. Group the causes by organ, start with the most likely, and for each one give the feature that supports or excludes it in your patient.

DiagnosisPoints to it in the historyPoints to it on examinationIn this patient
Gallbladder and bile ducts
Acute cholecystitisConstant pain for more than six hours, radiating to the right scapula, fever, vomiting, earlier attacks after fatty foodFever, tenderness and guarding, positive Murphy's sign, no jaundiceMost likely
Biliary colicPain after fatty meals that settles within hours; no feverNormal temperature, mild or no tenderness, Murphy's sign negativeHer earlier attacks
Bile duct stonePain with jaundice, dark urine, pale stools, itchingJaundice; often no feverNo jaundice
Ascending cholangitisPain, jaundice and fever with rigors (Charcot's triad)Jaundice, high fever; confusion and low blood pressure when severeNo jaundice, no rigors
Acute pancreatitisEpigastric pain through to the back, eased by leaning forward, repeated vomiting; gallstones or alcoholEpigastric tenderness, patient may be shockedPain pattern does not fit; check lipase
Liver
Acute hepatitisMalaise and loss of appetite before jaundice; contacts, travel, drugsJaundice, tender smooth enlarged liverNo jaundice, liver not enlarged
Liver abscess or infected hydatid cystSwinging fever, sweats, weight loss; contact with dogs or sheepTender enlarged liver, tenderness between the lower ribsUltrasound will exclude
Congested liverBreathlessness, ankle swelling, known heart diseaseRaised neck veins, tender enlarged liver, leg oedemaNo cardiac features
Stomach and bowel
Peptic ulcer, perforated ulcerEpigastric burning related to meals, anti-inflammatory drugs; sudden severe pain if perforatedEpigastric tenderness; board-like rigidity and loss of liver dullness if perforatedGradual onset, no rigidity
High or retrocaecal appendicitisCentral pain moving to the right side, loss of appetite, short historyTenderness lower and more lateral than the gallbladderUnlikely; no pain migration
Above the diaphragm
Right lower lobe pneumoniaCough, sputum, breathlessness, pain on breathingFast breathing, crackles or bronchial breathing at the right baseChest clear
Inferior myocardial infarctionOlder patient, cardiac risk factors, sweating, exertional painAbdomen soft with little tendernessUnlikely; ECG to exclude
Pulmonary embolismSudden breathlessness, pleuritic pain; recent immobility, the pillFast pulse and breathing, low oxygen saturation, swollen calfSaturation normal, calves soft
Kidney and others
Right pyelonephritisLoin pain, fever with rigors, burning urine, frequencyRenal angle tendernessNo urinary symptoms
Renal colicColicky loin-to-groin pain, blood in urine, restless patientLittle abdominal tendernessPain constant, patient lies still
ShinglesBurning skin pain in a band on one side, before the rashVesicles in one dermatomeNo rash
Pregnancy-related causesMissed period; late pregnancy with headache and swellingRaised blood pressure, pregnant uterusPregnancy test in every woman of childbearing age
Model OSCE answer “My most likely diagnosis is acute calculous cholecystitis, because of the constant right upper quadrant pain for two days with fever and a positive Murphy's sign, on a background of biliary colic. My differentials are a bile duct stone or cholangitis, which are less likely because she is not jaundiced; gallstone pancreatitis, which I would exclude with a lipase; and peptic ulcer disease. I would also exclude causes outside the abdomen, namely right lower lobe pneumonia and an inferior myocardial infarction, with a chest X-ray and ECG.”

Clinical signs related to this case

The signs you should look for in any patient with right upper quadrant pain. For each one, know how to elicit it and what a positive result means.

SignHow to elicit it, or what you seeWhat it means
Gallbladder, bile ducts and pancreas
Murphy's signHand under the right costal margin in the mid-clavicular line; the patient stops breathing in because of pain. Negative on the left.Acute cholecystitis
Boas' signIncreased skin sensitivity below the right scapulaAcute cholecystitis
Courvoisier's lawA palpable, non-tender gallbladder in a patient with painless jaundiceThe cause is unlikely to be stones; think of cancer of the head of the pancreas or periampullary region
Charcot's triadRight upper quadrant pain, fever with rigors, jaundiceAscending cholangitis
Reynolds' pentadCharcot's triad plus low blood pressure and confusionSevere cholangitis with sepsis; needs urgent drainage of the bile duct
Cullen's signBruising around the umbilicusBleeding behind the peritoneum: severe pancreatitis, ruptured ectopic pregnancy
Grey Turner's signBruising in the flanksBleeding behind the peritoneum: severe pancreatitis, leaking aortic aneurysm
Signs that point away from the gallbladder
Guarding and rigidityGuarding: muscles tighten when you press. Rigidity: muscles are board-hard all the time.Local guarding fits cholecystitis. Generalised rigidity means generalised peritonitis, for example a perforated ulcer.
Loss of liver dullnessThe area over the liver is resonant on percussionFree gas under the diaphragm: perforated ulcer
Tender enlarged liverSmooth, tender liver edge felt below the costal marginHepatitis, liver abscess or a congested liver
Renal angle tendernessPain on firm pressure or gentle percussion between the twelfth rib and the spinePyelonephritis
Signs at the right lung baseDull percussion note, crackles or bronchial breathingRight lower lobe pneumonia
