Diagnosis of malignant biliary strictures

Techniques in Gastrointestinal Endoscopy, 2002
It is important to determine the benign or malignant nature of a biliary stricture, and a tissue diagnosis is usually desirable. This article discusses methods for diagnosis of malignant biliary strictures, including bile cytology, biliary brush cytology, intraductal forceps biopsy, needle aspiration, scraping devices, and endoscopic ultrasound-guided ...

Endoscopic Management of Malignant Bile Duct Strictures

Gastrointestinal Endoscopy Clinics of North America, 2013
Malignant biliary obstruction can arise from intrahepatic, extrahepatic, and hilar locations from either primary or metastatic disease. Biliary-enteric surgical bypass has been surpassed in the last 20 years by endoscopic balloon dilation and stenting.

Stents for benign and malignant esophageal strictures

Annals of the New York Academy of Sciences, 2013
This paper presents commentaries on endotherapy for esophageal perforation/leaks; treatment of esophageal perforation; whether esophageal stents should be used for treating benign esophageal strictures; what determines the optimal stenting period in benign esophageal strictures/leaks; how to choose an esophageal stent; how a new fistula secondary to an

Stenting for Benign and Malignant Biliary Strictures

Gastrointestinal Endoscopy Clinics of North America, 2019
Benign and malignant biliary strictures are common indications for endoscopic retrograde cholangiopancreatography. Diagnosis involves high-quality cross-sectional imaging and cholangiography with various endoscopic sampling techniques. Treatment options include placement of plastic biliary stents and self-expanding metal stents, which differ in patency

Pancreatic Duct Strictures: Identifying Risk of Malignancy

Annals of Surgical Oncology, 2004
This study aimed to define PDS characteristics that predict malignancy and would thus invoke further diagnostic evaluation or aggressive treatment.355 cases of PDS were diagnosed by ERCP during a 7-year period at a single institution. A retrospective review identified clinical/demographic patient data and ERCP results.218 (61%) patients with a PDS were

Idiopathic ureteral strictures without evidence of malignancy

Urology, 2004
Benign strictures of the ureter without known antecedent cause are rare. In the absence of prior instrumentation, infection, radiotherapy, or ureteral calculi, strictures intrinsic to the ureter are usually of malignant origin. We describe two recent cases of idiopathic ureteral strictures without evidence of malignancy.

Expandable Metal Stents for Malignant Colorectal Strictures

Gastrointestinal Endoscopy Clinics of North America, 2011
The surgical management of malignant colorectal obstruction is still controversial and has higher associated mortality and complication rates compared with elective surgery. Placement of self-expanding metallic stents (SEMS) has been proposed as an alternative therapeutic approach for colonic decompression of patients with acute malignant obstruction ...

Management of Malignant Biliary Strictures

1997
Diagnosis of obstructive jaundice has improved recently with magnetic resonance cholangiopancreatography (MRCP) to show the precise site of the obstruction (SOTO et al. 1996). In papillary carcinoma, both the common bile duct (CBD) and the pancreatic duct are enlarged down to their distal part (Fig.
