A sequential sampling strategy, in which EUS-guided Trucut biopsy is attempted first, and FNA performed only when Trucut biopsy fails to obtain a macroscopically adequate sample, achieves a diagnostic accuracy of 92 %, with 11 % of patients requiring both sampling procedures.
Demonstration of fluid levels on MRI is well recognised in cerebral haematomas, tumours and cysts. The occurrence of fluid levels within haemorrhagic pituitary tumours has not previously been described in detail. Evidence of haemorrhage was identified in 27 of 125 pituitary tumours. Fluid levels occurred in 13 of these haemorrhagic tumours. No association with histological type was identified. Recognised risk factors for haemorrhage were identified in half of the cases.
The aim of this study is to review the practice and outcomes at our institution of percutaneous transhepatic placement of metallic biliary stents for non-hepato-biliary/pancreatic (non-HBP) malignant obstructive jaundice. A retrospective review was performed of the records of all patients undergoing transhepatic stenting for non-HBP malignant obstructive jaundice over a 7-year period. A total of 25 patients were successfully stented and linear regression analysis of a variety of demographic, clinical and laboratory markers against survival was performed. Survival after stenting varied from 1 to 1354 days (median 58, mean 152). An initial bilirubin level less than 300 micromol/L (P=0.01) and a reduction of greater than 50% in bilirubin post stenting (P=0.02) were strong predictors of improved survival. Older patients survived longer than younger ones (P<0.01). There was a weak association of survival with an albumin>30 g/L (P=0.06), but no statistically significant correlation with creatinine or haemoglobin levels or active tumour treatment after stenting. There were few major complications from the procedures. Transhepatic metallic biliary stenting for non-HBP malignant biliary obstruction is a safe and effective procedure, and with careful patient selection, significant periods of survival and palliation of jaundice can be achieved.
EUS as compared to asymptomatic patients (78% vs 22%), but this difference was not found to be statistically significant. Conclusion Performing EUS and ERCP in single sessions is a safe and effective strategy. Careful selection of patients for single session EUS-ERCP can avoid unnecessary high risk ERCP procedures. Patients who had planned combined procedure for suspected stone disease did not require significant extra time as compared to ERCP alone. We suggest that all ERCP requests should be reviewed by experienced endoscopists and prior EUS should be considered in selected patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
