RESUMO
AIMS AND OBJECTIVES: The study seeks to determine the advantages of using the pistol-grip syringe holder in the performance of FNAB over the use of direct finger grip method. PATIENTS AND METHODS: The skin is cleaned with gauze soaked in methylated spirit and the lump is located and firmly held between the thumb and fore finger of the free hand. The syringe is held by the out side of the barrel or by pistol-grip, and the needle tip pushed into the lesion. The plunger is partially retracted, creating a negative pressure. The cutting edge of the needle tip frees the cells inside the lesion which are sucked into the fine bore of the needle. The contents of the needle are then emptied on a microscopic slide and thinly smeared. The slides are then fixed in alcohol and later stained. These were examined under the microscope and a comparison between the aspirations using pistol-grip and direct finger grip was made. RESULTS: A total of 266 cases of FNABs were carried out from 1st January to 31st December, 2008. There were 89 breast cases out of which 42 (47%) had pistol-grip method and 47 (53%) had direct finger grip method; 74 thyroid cases out of which 28 (38%) were pistol-grip and 46 (62%) were direct finger grip cases; 56 cases of lymph node FNABs of which 18(32%) and 38 (68%) had pistol-grip and direct finger grip methods respectively. There were 23 cases of salivary gland FNABs having 8 (35%) and 15 (65%) as pistol-grip and direct finger grip methods respectively. Marked cellularity was observed in the majority of cases using both methods of FNABs. CONCLUSION: This study has shown that the use of pistol-grip syringe holder in the performance of FNABs has no significant advantage compared to the direct finger grip method.
