Publication Accuracy of ultrasonography in evaluation of level and cause of biliary obstruction: a prospective study(Kathmandu University, 2005) Ghimire, R; Lohani, B; Pradhan, SAim: To find out the accuracy of ultrasound in evaluation of level and cause of biliary obstruction. Materials and methods: Forty-five patients (26 to 86 years of age) with suspected biliary obstruction underwent Ultrasonography followed by Direct Cholangiograms (Percutaneous Transhepatic Cholangiography / Endoscopic Retrograde Cholangiography). The levels of biliary obstructions were grouped as hilar, suprapancreatic and intrapancreatic. Similarly the causes were grouped as malignant and benign. Diagnosis was confirmed either at surgery or histopathologically (USG-guided FNAC or ERC-biopsy). Results: Ultrasonography accurately identified the level of obstruction in 89 %( hilar), 91 %( suprapancreatic) and 87 %( intrapancreatic) cases. Malignancy was found in 33 patients and remaining 12 had benign diseases. USG accurately identified malignant and benign causes in 91% and 84% cases respectively. Findings were found to be statistically significant (p-value=<0.05 at 95%confidence interval). Conclusion: This study showed that USG has high accuracy in identifying the level and cause of biliary obstruction. Considering cost, availability and patient friendly nature, Ultrasound should be the first imaging modality of choice in evaluation of biliary obstruction.

It may be elevated in other prostatic diseases and surgical procedures. PSA exists in two forms, a major bound form (cPSA) and a free form (fPSA). Objectives: The objective of the study was to determine the relationship between serum fPSA levels and histologic findings in biopsy specimens of men with prostatic disease. Material and methods: This study includes 91 patients planned for transurethral resection of prostate (TURP). Blood samples were collected before TURP and tested for fPSA. Histology of the tissue samples collected after TURP were studied and the relationship with fPSA analysed using SPSS 11.5. Results: The median values for benign, premalignant and malignant lesions were 1.8ng/ml, 4.5ng/ml and 13.20ng/ml respectively (p<0.001). Most cases of benign prostatic hyperplasia(BPH) without inflammation had fPSA levels <2ng/ ml, while most with active inflammation had levels >5ng/ml. Low grade prostatic intraepithelial neoplasia (LGPIN) saw levels <5ng/ml while high grade intraepithelial neoplasia (HGPIN) and prostate cancer (PCa) had levels > 5ng/mL (p<0.05). For detection of high grade lesions (HGPIN and PCa), the sensitivity and specificity of fPSA level > 5ng/ml was found to be 88.8% and 90.2% respectively. Conclusions: Serum fPSA is elevated marginally in patients with BPH without inflammation. Active inflammation and high grade lesions are associated with fPSA level more than 5 ng/ml.
