Ultrasound is cheap, easily available imaging modality which is useful in detection of stent within the biliary tree, dilatation of biliary tree and in assessment of complications after ERCP. AIMS AND OBJECTIVE: Our study aims at to statistically assess the diagnostic accuracy and utility of ultrasound in assessment of biliary stent. MATERIAL AND METHODS: Total 221 patients from gastroenterology department were evaluated by ultrasound abdomen examination using Philips HD 11XE ultrasound scanner. Post ERCP clinical details were obtained. X-ray abdomen done in all cases with ERCP is done wherever required. RESULT: In our study we found following measures of diagnostic accuracy in detection of biliary stent. Sensitivity 77.27%, Specificity 94.59%, Accuracy 85.97%, Positive predictive value 93.40%, Negative predictive value 80.76%, Positive likelihood ratio 14.29, Negative likelihood ratio 0.24, Diagnostic odds ratio 59.50. Twenty cases showed biliary dilatation in presence of CBD stent. Out of these 4 cases showed presence of upper end of stent in tumor mass while in rest cases it was in dilated biliary tree. Post ERCP complications were noted in 11 cases. CONCLUSION: Ultrasound is a reliable, noninvasive, nonradiative imaging modality to assess presence of biliary stent, biliary dilatation in presence of stent and to assess tumor status and post ERCP complications. Hence we recommend the use of follow up ultrasound after ERCP procedure.

INTRODUCTION:Tissue harmonic imaging (THI) is a new ultrasound imaging technique providing the images which are much superior in quality compare to conventional ultrasound images by improving lateral resolution, signal to noise ratio and reducing side-lobe artifacts. AIM: Our aim is to estimate diagnostic accuracy of THI in diagnosing the cause of obstructive jaundice and to compare it with previous studies. MATERIAL AND METHODS: 125 cases of obstructive jaundice were evaluated with THI for the cause of obstructive jaundice by three radiologists separately during period of two year interval on Phillips HD 11 XE ultrasound scanner. Follow up done with ERCP, surgery and histopathology. CT and MRCP done wherever needed. Sensitivity, specificity, PPV, NPV, accuracy, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio and Youden's index were calculated and compared with previous studies. RESULT: In our study we found choledocholithiasis as most common cause for obstructive jaundice. Sensitivity of 80%, 57.49%, 70.97% and specificity of 90%, 90.59%, 89.36% was noted for choledocholitiasis, neoplasm and benign stricture respectively. Accuracy of 86.4%, 80%, 84.8% was found for choledocholitiasis, neoplasm and benign stricture respectively. PPV of 81.81%, 74.19%, 68.75% and NPV of 88.88%, 81.91%, 90.32% was observed for choledocholithiasis, neoplasm and benign stricture respectively. Positive likelihood ratio of 8, 6.10, 6.67 and negative likelihood ratio of 0.22, 0.46, 0.32 was noted for choledocholithiasis, neoplasm and benign stricture respectively. Diagnostic odds ratio and Youden's index of 36 and 0.7, 13.02 and 0.48, 20.53 and 0.60 was seen for choledocholithiasis, neoplasm and benign stricture respectively. CONCLUSION: Introduction of THI in the modern ultrasound equipment had made improvement in the diagnosis of cause for biliary tract obstruction. Till today even with THI ultrasound doesn't have higher diagnostic value.

“…None of the three cats with contrast filling of the common bile duct and the gallbladder had imaging characteristics consistent with biliary tract diseases such as dilations, strictures, obstructions, wall irregularities, or contrast leakage into the abdominal cavity . Also in the three cats with retrograde pancreatography, the duodenal and gastric branches of the main pancreatic ducts were clearly visible without any signs of duct abnormalities suggestive for pathologic processes.…”

Cats are predisposed to diseases of the biliary tract and the exocrine pancreas and these can be challenging to diagnose. In humans and dogs > 10 kg, endoscopic retrograde cholangiopancreatography (ERCP) has been successfully used to diagnose some of these disorders. The purpose of our study was to determine whether ERCP would also be feasible in cats using a pediatric duodenoscope. Four purpose-bred, clinically healthy, castrated domestic shorthair cats participated in two studies. Study 1 compared standard white light endoscopy with chromoendoscopy for localizing the major duodenal papilla. In Study 2 ERCP was performed. Repeated clinical examinations and measurements of serum feline pancreatic lipase immunoreactivity (fPLI) were performed before and up to 18 hours after interventions on all cats. Chromoendoscopy was subjectively judged to be superior for localizing the major papilla. Insertion of the ERCP catheter was best accomplished when cats were in dorsal recumbency. Complete ERCP was successful in two cats. In the other cats, either retrograde cholangiography or pancreatography was possible. Serum fPLI concentrations increased temporarily in two cats during Study 2 when measured immediately, 2, 4, and 18 h after ERCP. Peak fPLI concentrations were detected either immediately after ERCP or 2 h later. No clinical signs of complications were observed within 18 h after the procedures. Findings indicated that ERCP is technically demanding but feasible in healthy cats. Future studies need to determine whether the temporary increases in serum fPLI concentrations are clinically important and to investigate the utility of ERCP in feline patients.
