Specific Abdominal Examination Inspection The abdomen was symmetrical and not distended. There was no abnormal movement found with each respiration. The umbilicus was inverted and centrally located. There were no striae, no surgical scars, no prominent and dilated veins, no skin discolouration, no visible peristalsis, no pulsation and no obvious mass seen. Cough impulse shown right reducible inguinal hernia, measuring 5x5 cm in diametre. Upon further questioning, the patient said that the hernia was noticed ten years ago but he never went to hospital for follow-up. Palpation and Percussion Upon superficial palpation, the abdomen was soft and tender at right hypochondrium and right lumbar region on the abdomen. Upon deep palpation, the liver was palpable with two finger breadths below the costal margin. The spleen was not palpable. The kidney was not ballotable. There was no palpable mass found on the abdomen. Other parts of the abdomen were soft and normal.

There was no shifting dullness and fluid thrill was negative. Auscultation There was increased bowel sound heard. There was no renal artery bruit heard. Per rectal examination and genitalia examination were unremarkable. All other systems were unremarkable.

To check for any sign of anaemia or underlying infection

Type of specimen: Whole blood Results

40), obese, multiparous women • Familial cholelithiasis in tribes of North Americal Indians because small bile salt pool and Chileans because high cholesterol excretion • High calorie or high cholesterol diets which can produce supersaturated gallbladder bile • Drastic weight reduction and diets to lower cholesterol which can lead to mobilization of cholesterol and increased cholesterol excretion • Disease or resection of terminal ileum which favours cholesterol nucleation by reducing bile salt pool 13

• Drugs such as cholestyramine, oral contraceptive pills, diuretics and clofibrate which give effect of bile salt depletion • Pregnancy can increase bile stasis within gallbladder • Other

such as

VII.

Pathogenesis of gallstones The pathogenesis of gallstones formation can be explained by the figure below: Formation of cholesterol crystals

‘Cholesterol nucleation’ →due to combination of cholesterol molecules with particles of mucus, bacteria, calcium bilirubinate or mucosal cells

Excessive cholesterol excretion, reduction in amount of bile salt, lecithin available for micelle formation, bile is concentrated in gallbladder (favoured by stasis or decreased gallbladder contractility)

Bile becomes supersaturated with cholesterol

Gallstone formation

Acute cholecystitis It is an acute inflammation of gallbladder. It occurs when there is an obstruction at the neck of gallbladder or cystic duct by a stone and is associated with infection and thus causes systemic illness.

This will cause severe right hypochondriac pain radiating to the right scapular region and to the back. The pain usually associated with other symptoms such as fever, tachycardia, nausea, vomiting, chills and rigors. Upon physical examination, there is often generalized abdominal tenderness and rigidity and most markedly felt over the gallbladder. Murphy’s sign is usually present in patient with very inflamed gallbladder. The results of laboratory investigations may show leukocytosis as a sign of bacterial infection. Raised total bilirubin may indicate obstructive jaundice as presence of gallstones. Based on findings of ultrasound of the abdomen, multiple stones are present usually in the neck of gallbladder or cystic duct. The wall of gallbladder is also thickened with pericholecystic fluid indicating inflammation of gallbladder. Usually, 90% of the case is settled down with conservative treatment by keeping the patient nil by mouth, replacing intravenous fluids, giving antibiotics and painkiller and nasogastric suction is performed if appropriate. However, 10% of the case may develop disease progression with life-threatening complications such as gallbladder empyema, gangrene and perforation which will require surgical intervention such as open cholecystectomy.
