====Radiography====
====Radiography====
*Abdominal radiography may reveal free gas in the abdomen. This is highly suggestive of peritonitis
*Abdominal radiography may reveal free gas in the abdomen. This is highly suggestive of peritonitis. The serosal details may be loss. If taken with the patient standing, a fluid line may be seen.
*Thoracic radiograph should be assessed for signs of metastatic disease.
*Thoracic radiograph should be assessed for signs of metastatic disease.
====Ultrasonography====
*This is senstive for any free fluid in the abdomen.
*Possible causes such as abscesses of organs or rupture of gallbladder can be identified.
===Histopathology===
===Histopathology===
*Abdominal fluid collected for laboartory analysis via abdominocentesis. The fluid should be stained for intracellular bacteria and assessed for:
*Abdominal fluid can be collected for laboartory analysis via abdominocentesis. The fluid should be stained for intracellular bacteria and assessed for:
**amylase and lipase for pancreatitis
**amylase and lipase for pancreatitis
**bile for biliary leak

*Aggressive fluid therapy with crystalloid and colloid should be given on initial presentation to improve haemodynamic parameter.
*Aggressive fluid therapy with crystalloid and colloid should be given on initial presentation to improve haemodynamic parameter.
*Fluid therapy is also very important in the postoperative period. Both crystalloid and colloid should be continued until the the patient is normotensive. However, if hypotension continues, a vasopressor such as vasopressin should be considered.

*Supplementaion of glucose and potassium may be needed.
