TRANSCRIPT
APPROACH TO ACUTE ABDOMEN
What It Is
ACUTE ABDOMEN- acute attack of abdominal pain that may be sudden or gradual, with other symptoms
Denotes an underlying disorder that requires immediate attention and possibly surgical intervention
Careful history and examintaion, early diagnosis and treatment is crucial
Causes of Acute Abdomen
INTRA-ABDOMINAL / EXTRA-ABDOMINAL
Intra-abdominal1) Inflammation- acute appendicitis, acute cholecystitis, acute
salpingitis, amoebic liver abcess, acute pneumoccal peritonitis
2) Perforation- of peptic ulcer, typhoid ulcer, ulcerative colitis
3) Acute Intestinal Obstruction –
A) Mechanical- (i) in the lumen- gallstone, round worms
(ii) in the wall- tubercular stricture, intussception, growths
(iii) outside the wall- volvulus, external and internal hernia
B) Toxic – paralytic ileus
C) Neurogenic – Hirschsprungs’s
D) Vascular – Occlusion of mesentric vessels by embolism or thrombosis
4) Haemorrhage – spontaneous rupture of malarial spleen, rupture of ectopic gestation, ruptured lutein cyst
5) Tortion of pedicle- twisted of ovarian cyst, spleen
6) Colic – biliary, ureteric, appendicular, intestinal.
Extra-Abdominal
1. Parietal conditions: gas gangrene of the abdominal wall, abscess of the abdominal wall, rupture of rectus abdominus, superficial cellulitis of the abdominal wall
2. Thoracic conditions: lobar pneumonia, spontaneous pneumothorax, angina, pericarditis
3. Retro-peritoneal conditions- uremia, pyelitis, dissecting anwurysm of aorta
4. Diseases of spine, spinal cord, and intercostal nerves: pott’s disease, acute osteomyelitis, herpes zoster, tabes dorsalis
5. General diseases: malaria, typhoid, sickle cell anemia, purpura
HISTORY AND
EXAMINATION
HISTORY
Age Sex Occupation Social status
HISTORY: chief complaints
PAIN Time of onset: acute appendicitis, peptic ulcer Mode of onset: perforation, colic, torsion - sudden acute intestinal obstruction- gradual increase acute appendicitis- sudden increase Duration: periodicity, varying intensity Site of pain: pointing test flank- renal right costal margin- liver or gallbladder epigastric- perforation, pancreatitis Shifting: acute appendicitis- umbilicus to right iliac fossa due to parietal peritonitis Radiation: peptic perforation, spreading peritonitis Referred pain: epigastrium, around the umbilicus, hypogastrium, shoulder, loin to groin,
scapula Character of pain: colicky, constant burning pain, severe agonising pain, throbbing pain,
change in character of pain Pressure on pain Aggravating and relieving factors: jolting, walking, respiration, micturition (strangury),
lying still, fatty foods, alkalis, stooping, vomiting
VOMITING Character- projectile/regurgitation Vomitus- intestinal obstruction,
gastrocolic fistula, biliary colic, peptic ulcer, peritonitis and uremia
Frequency and quantity- frequent/periodical, nausea characteristic of appendicitis
With respect to pain: appendicitis, pancreatitis, colic, in high obstruction
BOWEL HABITS Constipation-obstruction,
appendicitis, peritonitis Tenesmus- pelvic appendicitis,
abcess, rectum Diarrhoea- colitis, acute enteritis,
ileitis
MICTURITION Strangury Hematuria – retrocaecal appendicitis

General examination
Appearance Attitude Pulse Respiration Temperature tongue
inspection- Contour: - Scaphoid or flat in peptic ulcer- Distended in ascites or intestinal obstruction- Visible peristalsis: in a thin or malnourished
patient (with obstruction)-laddar pattern- Respiration-sluggish in peritonitis- Pulsating swelling- aneurysm- Skin discoloration- grey turner’s sign and
Cullen’s sign
palpation
Cutaneous hyperaesthesia
Either lift the skin or stimulate the skin with gentle jabbing with a sterile pinIndicates a zone of peritoneal irritation
RLQ -- appendicitisMid Epigastrium -- peptic ulcer
Tenderness
Degree and extent Bed-shaking test(Bapat)-peritonitis Spread Appendicular tenderness in left
lateral position
Rebound tenderness
Apply firm pressure for several seconds to the abdomen with hand at right angles and fingers extended Quickly release the pressure Test away from site where pain is initially determined
Pain at site is direct rebound tenderness
Pain at another site is referred rebound tenderness
Indicative of peritoneal inflammation
Rovsing’s sign
Press in the LLQ evenly for 5 seconds and note if patient has pain in RLQ – positive- Gas is pushed through the ileocecal valve thus distending the cecum-In acute appendicitis- positive
Cope’s Psoas Test Place your hand over the right thigh
and push downward as the patient is trying to raise the leg, flexing the hip
Positive RLQ pain associated with a retrocaecal or perforated appendicitis
Obturator Test
Flex the right leg at the hip and knee at a right angle then rotate the leg internally and externally
Pain indicative of inflammatory process over obturator muscle Ruptured appendix Pelvic abscess
Muscle Guarding Use both hands -- one on each rectus Check for tensing during expiration When positive it is indicative of
peritoneal irritation -- peritonitis

auscultation
Auscultation BS > 2min to confirm absent High pitched, hyperactive or tinkling Bruit in epigastrium Noisy abdomen-acute intestinal
obstruction Silent abdomen- peritonitis
