17. ONSET OF PAIN
The onset is typically sudden in:
Perforation of a viscus
Infarction of a bowel
Rupture of an aortic aneurysm
It tends to be more gradual in inflammation:
Acute appendicitis
Acute cholecystitis
Acute pancreatitis
Acute diverticulitis
Acute pyelonephritis
Acute salpingitis
Gastroenteritis
3/9/2024 ACUTE ABDOMEN 17

18. TYPES OF PAIN
•Bowel colic is usually punctuated by pain
free periods
•Renal colic is characterized by severe
spasm superimposed on a more constant
pain in a restless
•Biliary colic is a steadily increasing pain
which crescendoes over 1-3hours
•Visceral pain is vague and poorly localized
•Sometic or peritoneal pain is accurately
localized and constant

21. RELIEVING OR AGGRAVATING FACTORS
PERITONITIS
Pain is relieved by lying still and aggravated
by movement
COLIC – Intestinal, Biliary or Renal
- The patient finds it impossible to lie still
 All foods aggravate GU pain
 Fatty foods aggravate gallbladder pain
 Food and Antacids relieve DU pain
 Vomiting relieves pain in acute gastritis, GU and
intestinal obstruction
3/9/2024 ACUTE ABDOMEN 21

22. DURATION OF PAIN
•A short history suggests acute
inflammation
• Acute appendicitis
• Acute cholecysitits
• Acute pancreatitis
•A long history of abdominal pain before the
acute episode may suggest
• Perforated DU
• Typhoid perforation
• Intestinal obstruction due to
- Neoplasm
- Volvulus
3/9/2024 ACUTE ABDOMEN 22

23. AGE OF PATIENT
• Children - Intussusception
• Young adults - Acute appendicitis
• Adults – Colorectal cancer
Vascular disease e.g. infarction
3/9/2024 ACUTE ABDOMEN 23

24. ANOREXIA, NAUSEA, VOMITING
• Anorexia – Prominent in Acute
Appendicits
• Nausea & Vomiting is frequent in
• Gastritis
• Gastroenteritis
• Pancreatitis
• High intestinal obstruction
• Bilary colic
3/9/2024 ACUTE ABDOMEN 24

25. • Vomiting is profuse in
• Gastroenteritis
• High intestinal obstruction
• Gastric outlet obstruction
• In intestinal obstruction it is
• Initially clear
• Then bile-stained
• Finally brown or faeculent
3/9/2024 ACUTE ABDOMEN 25

26. CONTENT OF VOMITUS
• Old food – suggests G.O.O
• Presence of blood
• Erosive gastitis
• Gastric carcinoma
• Reflux Oesophagitis
• Mallory-Weiss syndrome
3/9/2024 ACUTE ABDOMEN 26

27. BOWEL ACTION
• Constipation - Appendicitis, Int. obstruction
• Diarrhoea – Gastroenteritis
• Blood & Mucus - Dysentery, U. Colitis
• Red-current
Jelly stools - Intussusception
• Bleeding PR – Peptic ulcer
- Amoebiasis
- Enteric Fever
- Diverticular Disease
Mesenteric infarction
3/9/2024 ACUTE ABDOMEN 27

28. URINARY SYMPTOMS
• Urinary tracts infection
• Frequency
• Dysuria
• Renal & Ureteric Calculi
• Haematuria
• A missed period raises the possibility of an ectopic
pregnancy and vaginal discharge will suggest salpingitis
