Modern Management of Benign Bile Duct Strictures

چکیده
The diagnosis and treatment of benign biliary strictures (BBS) are often challenging. In the past, surgery was the treatment of choice in the majority of cases. Nowadays the endoscopic treatment of BBS is preferred over surgery because it is less invasive, repeatable and associated with lower morbidity rates. The endoscopic retrograde cholangiopancreatography (ERCP) can make the diagnosis of the stricture, and provide its dilation and stent placement. Temporary insertion of multiple side-by-side large-bore plastic stent is the standard of care in endoscopic therapy. The use of uncovered self-expanding metal stents is under investigation. Most commonly BBS occur in the evolution of chronic pancreatitis, and after liver transplant or cholecystectomy. The efficacy of endoscopic therapies is different and depends on the cause of BBS. Though it has limitations, endoscopic therapy has a favourable safety profile and remains a first-line management option in benign biliary strictures. REZUMAT Managementul modern al stenozelor biliare benigne Stenozele biliare benigne reprezintã o patologie cu abordare diagnosticã æi terapeuticã deseori dificilã. În trecut principalul tratament în majoritatea cazurilor era chirurgical. Astãzi terapia endoscopicã este preferatã având în vedere cã este minim invazivã, poate fi repetatã æi are rate reduse de morbiditate. Colangiografia endoscopicã retrogradã (ERCP) este utilã pentru stabilirea diagnosticului æi realizarea dilatãrii æi stentãrii stenozei. Inseråia temporarã de stenturi biliare de plastic multiple reprezintã tratamentul endoscopic standard. Eficienåa utilizãrii stenturilor biliare metalice expandabile neacoperite este în curs de evaluare. Majoritatea stenozelor biliare benigne apar în evoluåia pancreatitei cronice, dupã colecistectomie sau dupã transplant hepatic. Rezultatele terapiei endoscopice diferã în funcåie de etiologia stenozei. Deæi nu este eficient în toate cazurile, tratamentul endoscopic are un profil de siguranåã acceptabil æi este prima linie de abordare a stenozelor biliare benigne. El poate fi util ca “punte” cãtre tratamentul chirurgical în unele cazuri de pancreatitã cronicã sau stenoze post-transplant hepatic.

Bile Duct Brush Cytology - Challenges, Limitations and Ancillary Studies
The use of Endoscopic Retrograde CholangioPancreatography (ERCP) was first reported in 1968 and since then it has served as an effective technique in evaluation and treatment of pancreatic and biliary diseases. Osnes et al. introduced use of brush with ERCP in mid 1970s, and brush cytology of the bile duct, pancreatic duct, common bile duct and the ampulla has become an established tool in eval...
متن کاملCurrent treatment of benign biliary strictures
Endoscopy is a widely used approach for the treatment of benign biliary strictures. Most common benign biliary strictures amandable to endoscopic treatment are post-cholecystectomy, dominant biliary strictures due to primary sclerosing cholangitis, biliary anastomotic strictures occurring after liver transplantation, and common bile duct strictures due to chronic pancreatitis. Surgery is a vali...

Biliary strictures both benign and malignant, remain one of the most difficult problem encountered by the surgeons. The vast majority of bile duct strictures are iatrogenic and occur mainly as a complication of cholecystectomy, despite greater awareness of the problem and safer techniques of dissection during biliary surgery. Malignant strictures involving the bile ducts remain a major challeng...

The diagnostic accuracy of percutaneous transhepatic cholangioscopy (PTCS) was compared to that of three radiologic modalities in distal common bile duct (CBD) strictures for the evaluation of clinical application. Ninety-five patients who underwent PTCS for the evaluation of distal CBD strictures (35 malignant and 60 benign) whose masses were not obvious from radiologic imagings were included....

Nineteen biliary strictures were dilated using a modified angioplasty balloon catheter to allow insertion of a 10F prosthesis. In each instance biliary strictures were successfully dilated which had previously been too tight to widen with standard endoscopic biliary dilating catheters. Eleven patients had malignant hilar strictures, four malignant distal common bile duct strictures, and four be...
