Endoscopic ultrasonographic access and drainage of the common bile duct.

Percutaneous transbiliary biopsy Biópsia percutânea transbiliar

Percutaneous drainage of the bile ducts is an established procedure for malignant obstructions, in which a histological diagnosis is often not obtained. We describe the biopsy technique of obstructive lesions through biliary drainage access, using a 7F endoscopic biopsy forceps, widely available; some are even reusable. This technique applies to lesions of the hepatic ducts, of the common hepat...

Ultrasound-guided drainage of walled-off pancreatic necrosis. Case report.

ERCP (endoscopic retrograde cholangiopancreatography) represents a safe endoscopic procedure and serious complications (perforation, haemorrhage, and acute pancreatitis) are usually uncommon. We present the case of a 38-year-old patient with gallstones in the common biliary duct who developed acute pancreatitis after ERCP. One month later a huge fluid collection with necrotic tissue in the righ...

The use of modern techniques of biliary tract monitoring in percutaneous drainage.

The aim of this work is to assess the usefulness of current imaging techniques of biliary tracts in percutaneous transhepatic biliary drainage (PTBD). In the period from January 1996 to March 2003 44 cases of PTBD were carried out under ultrasonographic and X-ray control in 34 patients who could not have a bypass or endoscopic prothesis of the bile duct. The effectiveness of the method was eval...

Retained common bile duct stones after endoscopic sphincterotomy: temporary and longterm treatment with biliary stenting.

Basket extraction after endoscopic sphincterotomy failed to clear the bile ducts immediately in 85 (30%) of 283 consecutive patients with common bile duct stones. Temporary biliary drainage was established by the insertion of a single 7 Fr double pigtail stent before further planned endoscopic attempts at stone removal. In 84 patients (21 male: 63 female, mean age 77 years) this measure relieve...
