not-yet-known not-yet-known not-yet-known unknown Diagnosis and Investigations. The clinical presentation raised suspicion of iatrogenic acute pancreatitis as a complication of the cholecystectomy. On blood testing serum amylase (1758 U/L) and lipase (2341 U/L) levels were elevated respectively. Serum LDH was also elevated at 365 U/L and raised total leukocyte count of 16,400/µL was noted. No significant findings appeared on urine analysis and negative results were found in initial blood culture and sensitivity at 48 hours. Abdominal ultrasound suggested no dilatation of duct with normal diameter of common bile duct (CBD) of 0.3 cm [Fig-1]. Ranson’s score on admission was two (elevated WBC and LDH). On the basis of history, examination and investigation, iatrogenic acute pancreatitis post-cholecystectomy was considered to be the final diagnosis.
