This document provides guidance on evaluating and diagnosing abdominal pain. It emphasizes the importance of thorough history taking and examination. Key vital signs and pain scores should be assessed. Analgesics can be given early without delaying diagnosis. Stability must be reassessed after interventions. Specific considerations are provided for different age groups and gender. Common patterns associated with various diagnoses are outlined. Four case studies are presented highlighting errors in diagnosis, including appendicitis mistaken for wall abscess, hernia nerve entrapment, testicular torsion, and opioid overdose masked by vague complaints. The takeaway is to be diligent and persistent until reaching a diagnosis.
2. • Its 3am in your night shift, and a nurse tells
you that a patient is waiting in traige with
Abdominal pain persistent since 8hrs today...
What would run through your mind?
9. Pain & Examination
• Breaking the Myth : “ Do not give Analgesia to
patients with Acute abdomen as it obscures
the Diagnosis ”
• As per Cochrane Review – Trials suggested no
delay in Diagnosis by providing early
Analgesics to patients with Abdominal Pain.
10. Assess for Stability
• Not all Patients with Abdominal Pain should
be managed in Triage Area!!
• All Unstable Patients should be reevaluated
every 30mins and also after every Medical
Intervention that you do.
11. Abdominal Pain - Reproductive Age Group
• For Females – Think of a Gynaecological or
Obstetric Cause!
Always do a Urine Pregnancy Test. (Especially if
taken for Imaging)
Famous Saying – “A Female in Reproductive age with
abdominal pain should be considered Pregnant until and
unless proven otherwise.”
• For both Males & Females –
- Take an Elaborate Sexual History
- Do a complete Genito-Urinary Examination
12. Abdominal Pain – Elderly Age Group
• May have Vague and Atypical Symptoms
• Fever is not a reliable Marker & WBCs have low
predictive value for Surgical disease.
• If Diagnosis is in Doubt – Liberal Imaging /
Admission / Observation Policy is strongly
advocated.
Diagnostic Key steps:
• Do a Digital Rectal Examination for all Elderly
Patients (A very valuable tool which is often
ignored)
13. No one can be this Happy before a PR Examination!
24. Case 1 - Appendicitis, Oh wait, is it?

25. • USG Abdomen – Probe Tenderness in Right
Iliac fossa, Improperly Visualized Appendix
due to excessive Bowel Gas

detected
Any ideas about the Diagnosis?

Pseudomonas Aeruginosa
Note: This was Diagnosed after
Surgeon went looking for this in CT
Scan and then a Biopsy was taken
27. Case 2 -Left Iliac Fossa – A Forgotten Quadrant
