Acute Abdomen
• Challenge to Surgeons & Physicians• Most common cause of surgical
emergency admission• Clinical course can vary from from
minutes to hours to weeks.• It can be an acute exacerbation of a
chronic problem e.g. Chronic Pancreatitis,Vascular Insufficiency.

DEFINITION
• Acute Abdomen is a term used synonymously for a condition that needs immediate surgical intervention
![Page 4: Acute Abdomine](https://reader034.fdocuments.net/reader034/viewer/2022052411/556afd68d8b42a2a4f8b4d86/html5/thumbnails/4.jpg)
ASSESMENT
• Well elicited history• Proper physical examination Diagnosis can be made most of Diagnosis can be made most of
the time by a good history and a the time by a good history and a proper physical examination.proper physical examination.

Assesment(cont.)
Investigations are usually carried out :
• only to support the diagnosis.• or to narrow down the differential
diagnoses.

PAIN
• The Most Important SymptomHistory of pain should include:1. Onset2. Severity3. Type of pain4. Radiation of Pain5. Change in nature of Pain6. Associated bowel or urinary symptoms7. Aggravating or relieving factors
![Page 8: Acute Abdomine](https://reader034.fdocuments.net/reader034/viewer/2022052411/556afd68d8b42a2a4f8b4d86/html5/thumbnails/8.jpg)
(i) Onset of Pain
• Sudden onset pain which wakes the patient from sleep
eg. perforation or strangulation of bowel• Slow insidious Onset a. Inflammation of visceral peritoneum. b. Contained process such as evolving
abscess.• Crampy or colicky pain

NAUSEA & VOMITING
• Pain first, followed by Vomiting is usually surgical.
The vomiting is due to ‘reflex pylorospasm’
• Nausea & vomiting first , followed by pain is usually due to a medical condition
