ABSTRACT
Objective: To compare the percutaneous radiologically guided gastrostomy [PeRG] tubes of wide caliber with narrow caliber tubes
Methodology: This retrospective study was performed on 36 patients who were referred to Radiology department for PeRG tube placement between 2008 till 2012. Comparison of wide caliber gastrostomy tubes [18-24 Fr] was done with narrow caliber tubes [14 Fr] considering procedure success rate, procedure related complications and catheter related minor and major complications
Results: Out of 36 patients, 18 patients were present in each group. Mean age of patients was 53.944 +/- 19.380. Procedure success rate was 100% in both groups and procedure related immediate complications were none in either groups. Peri-catheter leakage was observed in 1 patient in each group. Tube occlusion was present in 2 patients in narrow caliber group. Two patients had severe pain in wide caliber group and also 3 patients had wound infection in this group
Conclusion: Regardless of the type of radiologic catheter placed, PeRG can be considered as safe and highly successful procedure. Use of a 24 Fr gastrostomy tubes may show promising results if placed under radiological guidance with comparable technical success and complication rates to other caliber tubes

Objective: to compare bone marrow biopsy needle [BMBN] with bone biopsy needle [BBN] in CT guided core biopsies considering size of core, diagnostic yield and cost of needles
Methodology: retrospective study was done on 50 out of 68 patients referred to Interventional Radiology department for CT guided bone biopsy from 2008 till 2013. Grading of specimen length was done as small, medium and large. Diagnostic yield was determined on basis of clinical, imaging and histopathology data. Local cost of both needle types was determined. Comparison was made and statistical analysis was performed
Results: biopsy was performed by BBN in 16 patients and by BMBN in 34 patients. Overall diagnostic yield of bone biopsies was 82% [41 of 50 biopsies]. Diagnostic yield with BMBN was 85% and with BBN was 75%. Overall longer specimen length was obtained using BMBN. Statistically, there was no significant difference between them in diagnostic yield and specimen length; however, BMBN costs almost one half than BBN
Conclusion: diagnostic yield and sample length using bone marrow biopsy needle proved to be equivalent to bone biopsy needle. Bone marrow biopsy needle has an added benefit of being low in cost. Despite being a non-coaxial technique these needles can achieve diagnostic yield comparable to that of coaxial techniques as reported in past literature
ABSTRACT
Objective: To assess the diagnostic accuracy of Magnetic Resonance Imaging [MRI] in the pre operative evaluation of perianal fistulae
Methodology: Between Decemebr 2010 and January 2013, thirty patients with clinical suspicion of perianal fistulae had MRI scans done for evaluation of extent of disease. Out of these 11 patients underwent surgery in our hospital and were included in the study. All patients had body-coil MR Imaging examinations including the following sequences for anatomic and pathologic information: T2 sagittal, T1, T2 and STIR axial oblique, T2 and STIR coronal oblique and post contrast T1 FAT SAT sagittal, axial oblique and coronal oblique planes. Scans were interpreted by a senior radiologist with more than 5 year experience in body MR imaging. Surgical findings were accepted =as the gold standard and were recorded independently by the surgeon. MRI findings were compared with surgical findings using Park's classification
Results: The MRI findings were in accordance with surgical findings in 10 out of 11 patients regarding type and extent of fistula in ano. In one patient peroperatively diagnosed and treated fistula did not show on MRI. Statistical parameters showed that MRI has a sensitivity of 90%, specificity of 100% and diagnostic accuracy of 90% in determining type and extent of perianal fistula
Conclusion: MRI is an accurate and non invasive imaging modality for determining type and extent of peri-anal fistula and helps in pre operative management and surgical planning by giving correct assessment of extent of disease
