Endoscopic ultrasound-guided transduodenal placement of a fully covered metal stent for palliative biliary drainage in patients with malignant biliary obstruction
Surgical Endoscopy, 2011Co-Authors: Ali A. Siddiqui, Jayaprakash Sreenarasimhaiah, Luis F. Lara, William Harford, Calvin Lee, Mohamad A. EloubeidiAbstract:Background Endoscopic ultrasound (EUS)-guided biliary drainage (EUSBD) has been described as a viable alternative to percutaneous transhepatic cholangiography (PTC) in patients in whom ERCP has been unsuccessful. The purpose of our study was to assess the utility of EUSBD using a newly released, fully covered, self-expanding, biliary metal stent (SEMS) for palliation in patients with an obstructing malignant biliary stricture. Methods We collected data on all patients who presented with obstructive jaundice and who underwent transduodenal EUSBD after a failed ERCP. Eight patients presented with biliary obstruction from inoperable pancreatic cancer or cholangiocarcinoma. Reasons for failed ERCP were Duodenum Stenosis, high-grade malignant Stenosis of the common bile duct, periampullary tumor infiltration, failure to access the common bile duct, and periampullary diverticulum. EUS was used to access the common bile duct from the Duodenum after which a guidewire was advanced upwards toward the liver hilum. The metal stent was then advanced into the biliary tree. Technical success was defined as correct stent deployment across the Duodenum. Clinical success was defined as serum bilirubin level decreased by 50% or more within 2 weeks after the stent placement. Results Technical and clinical success was achieved in all eight patients. No stent malfunction or occlusion was observed. Complications included one case of duodenal perforation, which required surgery, and one case of self-limiting abdominal pain. Conclusions EUSBD with a fully covered SEMS in whom ERCP is unsuccessful is effective for palliation of biliary obstruction. The limitations of our study are that we had a small number of patients and a limited follow-up time.

the x ray feature of congenital Duodenum Stenosis complicated by small intestine malrotation
Applied Journal of General Practice, 2006Co-Authors: Tang YaobingAbstract:Objective To study the X-ray feature of congenital Duodenum Stenosis complicated by small intestine malrotation and evaluate the value of X-ray examination to congenital Duodenum obstruction.Methods The X-ray feature of congenital Duodenum Stenosis complicated by small intestine malrotation which confirmed by surgery were analyzed retrospectively and summarized,abdominal plain film,radiography with iodine solution of upper digestive tract and barium enema were performed in all patients.Results On the plain film,double bubble or tri-bubble were found in all cases.Dilatation of stomach,too much leftover in stomach,Duodenum dilataltion above stensosis and reversed peristalsis were noticed in opacification of upper digestive tract with meglumine diatrizoate.Lune prolapse were noticed in cases of membranous Stenosis.Little meglumine diatrizoate reach to other small intestine and colon,and spend much time.The filament of meglumine diatrizoate were noticed slowly go through the Stenosis bowel.Conclusions Congenital Duodenum Stenosis is the cause of congential Duodenum obstruction,which complicated with small intestine malrotation or other malformations.Radiography and contrast examination can offer important value to clinical diagnosis.
