Aims and Objectives

• Requires some basic knowledge of clinical examinations

• Clinical examination station (OSCE) • Abdominal examination: 4 cases

• Duration: 70 mins • Slides and recordings: www.bitemedicine.com/watch

2 Abdominal examination: OSCE Cases list

What cases could come up? 1. Renal transplantation (+ AV fistula) 2. Stoma 3. Chronic liver disease 4. Hepatosplenomegaly 5. Cushing’s syndrome

This is not an exhaustive list • But by preparing for these you will be better at: • Your exam routine • Looking out for important signs • Formulating your findings systematically • Tackling the VIVA

3 How to present your findings?

I performed an abdominal examination on this patient If you have an idea, then • Who has signs suggestive of XXX back yourself from the start. It gets the examiner listening My main positive findings are: 1. XXX 2. YYY

My relevant negative findings are: RELEVANT negatives 1. XXX (Risk factors) 2. YYY (Signs of decompensation) 3. ZZZ (POSSIBLE associated features)

Overall, this points towards a diagnosis of XXX with no signs of decompensation

4 Abdominal examination: Case 1

Background 65M Central (1) (2) • Palpable mass in the left iliac fossa Bedside/peripheral

Tacrolimus

5 Question 1 Q1 Q2

Abdominal examination: Case 1 – Renal transplantation

How to determine the presence of a renal transplant? • Mass in the iliac fossa • Rutherford-Morrison scar • Immunosuppressive • Look for evidence of previous haemo- or peritoneal dialysis

(3)

8 Abdominal examination: Case 1 – Renal transplantation

(5) Dialysis

Inspect the AV fistula • Wrist: radiocephalic • Antecubital fossa: brachiocephalic (or brachiobasilic) • Needle marks: suggests recent use

Palpate for a thrill and auscultate for a bruit • Both absent if ligated after transplantation (4) or thrombosed 9 Abdominal examination: Case 1 – Renal transplantation Please present your findings

I performed an abdominal examination on this 65M who has evidence of a renal transplant, likely secondary to diabetes mellitus.

My main positive findings: • By the bedside, I noted the presence of tacrolimus, likely as a post-transplantation immunosuppressant • Peripherally, the patient has evidence of BM fingerprick testing, suggestive of diabetes as the underlying cause, white patches on the tongue, and a right-sided non-active AV fistula in the antecubital fossa with no associated fluid thrill or bruit • On inspection of the , I noted a 7cm, well-healed, oblique, curvilinear scar extending across the LIF • A 10 x 6cm, smooth, non-tender mass was palpated in the LIF, which had a dull note

10 Abdominal examination: Case 1 – Renal transplantation Please present your findings

My relevant negative findings : • No Cushingoid features • No clinical evidence of mineral bone disease • No clinical evidence of immunosuppressive toxicity

In summary, this is a 65 M with a renal transplant and previous haemodialysis, likely necessitated by diabetes mellitus, as well as iatrogenic oral candidiasis due to immunosuppressant use.

11 Abdominal examination: Case 1 – Renal transplantation What are your differentials?

Key indications for renal transplantation • Diabetes mellitus • Hypertension • Chronic glomerulonephritis • Genetic e.g. polycystic kidney disease • Autoimmune e.g. lupus

12 Abdominal examination: Case 1 – Renal transplantation

What would you like to do next? • Full history and review immunosuppressants • Peripheral and fundoscopy: assess for other DM complications • Full set of observations

Bedside investigations •

Bloods • FBC: leukopaenia in view of immunosuppressant use • Renal profile: function of transplanted kidney • Calcium and phosphate levels: biochemical evidence of renal mineral bone disease • BM and HbA1c: history of DM and likely to be on steroids • Tacrolimus level

13 Question 2 Q1 Q2

How would you differentiate between a kidney and the spleen on examination?

The spleen is ballotable

The kidney has a notch

The kidney moves down on inspiration

The kidney enlarges inferiorly

You cannot get above the kidney

How would you differentiate a kidney from a spleen on examination?

Kidney Spleen No notch Splenic notch Does not move on respiration Moves down on inspiration Can get above it Cannot get above it Ballotable Cannot be balloted Enlarges inferiorly Enlarges towards the RIF

16 Abdominal examination: Case 2

Background Central 41M • Stoma bag is filled with liquid faeces

Bedside

(6) 17 Question 1 Q1

What is the most prominent finding on examination?

Percutaneous endoscopic gastrostomy

Colostomy

Urostomy

Ileostomy

Percutaneous endoscopic jejunostomy

app.bitemedicine.com 18 Abdominal examination: Case 2 – Stoma

Ileostomy Colostomy Urostomy Typical location Right iliac fossa Left iliac fossa Usually in the right iliac fossa Spouted or Spouted Flush Spouted flush? Contents of bag Liquid small Faecal matter Urine bowel contents

• Remove bag (if possible) • Site • Number of lumens 1 lumen • Spout • Effluent • Cough impulse (7)

(8)

(9) 19 Abdominal examination: Case 2 – Stoma Please present your findings

I performed an abdominal examination on a 41M with a healthy end ileostomy

My main positive findings: • By the bedside, I noted the presence of a stoma bag • Inspection of the abdomen revealed a single lumen, spouted stoma in the right iliac fossa containing liquid faeces, suggestive of an end ileostomy

20 Abdominal examination: Case 2 – Stoma Please present your findings

My relevant negative findings: • No evidence of stoma-related complications • Parastomal : enlargement of the stoma, increased hernia size when coughing, bulging • Stoma infarction: pain at the stoma site, necrosis (black colour) of the stoma • Other: stoma prolapse, retraction, haemorrhage • No evidence of infection, and healthy surrounding skin

In summary, this is a 41M with a healthy end ileostomy. There is no evidence of stoma-related complications.

(10)

21 Abdominal examination: Case 2 – Stoma What are some indications for an ileostomy? • Inflammatory bowel disease • Familial polyposis • Colorectal cancer • Intrabdominal sepsis or haemorrhage

End ileostomy vs. Loop ileostomy

N.B remember an ileostomy may be temporary or permanent, and may be used to defunct a complex distal anastomosis, to divert faeces if the entire colon is removed

22 Abdominal examination: Case 2 – Stoma

What would you like to do next? • Full history • Review fluid balance and stoma output • Full set of observations

Bloods • Electrolyte panel: ileostomies are associated with significant electrolyte abnormalities if high-output • FBC and CRP: if evidence of complications

Imaging • CTAP: if evidence of complications e.g. parastomal hernia
