title: Comparative study of ultrasound guided fine needle aspiration cytology with open/laparoscopic biopsy for diagnosis of carcinoma gallbladder.
abstract: OBJECTIVE
  To determine the accuracy of Fine Needle Aspiration Cytology (FNAC) in cases of gallbladder mass.
  
  
  METHODS
  Comparative study.
  
  
  METHODS
  Surgical Units of Mayo Hospital, Lahore and Lahore General Hospital, Lahore in collaboration with the Department of Radiology, Sir Ganga Ram Hospital, Lahore and Department of Pathology of PGMI, Lahore, from September 2006 to September 2007.
  
  
  METHODS
  Ultrasound guided fine needle aspiration cytology was done in all cases and histopathological findings were confirmed with open/laparoscopic biopsies. The results of these two modalities were compared.
  
  
  RESULTS
  Fifty cases with mean age 60.71+11.073 years presented with mass gallbladder underwent FNAC. Smears showed adenocarcinoma 23, undifferentiated carcinoma in 7, dysplasia and suspicion of malignancy in 5, hemorrhagic background without malignant cells in 12 and inflammatory cells with no malignancy in 3 cases. Results compared with open/ laparoscopic biopsy showed a sensitivity, specificity and Positive Predictive Value (PPV) of 72.91%, 100% and 100% respectively.
  
  
  CONCLUSIONS
  Ultrasound guided FNAC is a safe and less invasive diagnostic modality for diagnosing carcinoma gall bladder preventing the patient to undergo major surgery and helps in better quality of life.
