The large-balloon occupation technique: a new technique for removing multiple biliary stones from a large-diameter bile duct
ثبت نشده
چکیده
Multiple stones, a periampullary diverticulum, and advanced patient age are factors that contribute to difficulty in stone removal [1]. We were able to completely remove the bile duct stones in a 93-year-old woman with a periampullary diverticulum, multiple stones (about 100), and common bile duct of 35mm in diameter using the large-balloon occupation technique (LBOT). The patient visited our hospital because of abdominal pain, and gallstone pancreatitis was diagnosed. Computed tomography (CT) scanning showed about 100 stones in the bile duct (▶Fig. 1) and an impacted stone in the papilla. Emergency endoscopic biliary drainage was therefore performed. After the patient’s pancreatitis had improved, endoscopic lithotripsy was performed. Endoscopic retrograde cholangiography (ERC) showed a markedly dilated bile duct (35mm) and many filling defects with diameters of 3–12mm (▶Fig. 2). At the first session of endoscopic lithotripsy, we were unable to E-Videos

متن کاملEndoscopic Papillary Balloon Dilation with Large Balloon after Limited Sphincterotomy for Retrieval of Choledocholithiasis
Endoscopic papillary balloon dilation (EBD) for choledocholithiasis is known to be comparable to endoscopic sphincterotomy (EST) especially in cases of small stones. With larger stones, EBD with conventional balloon, which have a diameter of 6-8 mm, was reported as less effective for extraction of stones. We evaluated the efficacy and complications of EBD with large balloons (10-15 mm) after li...
متن کاملPeroral cholangioscopy: use of a Roth Net retriever for difficult biliary stones.
Bile duct stones are routinely removed during endoscopic retrograde cholangiopancreatography (ERCP) with biliary sphincterotomy, using standard balloon or basket extraction techniques. However, in approximately 10%–15% of patients, bile duct stonesmay be difficult to remove owing to challenging access to the bile duct, large bile duct stones (>15mm in diameter), intrahepatic stones, or impacted...
متن کاملBenign retropneumoperitoneum developed after endoscopic sphincterotomy and large balloon dilation of biliary sphincter for removal of large biliary stones: a case report
Biliary endoscopic sphincterotomy (ES) followed by biliary orifice dilation (BOD) with large-diameter balloons (> 12 mm) is a relative new technique for extraction of large biliary stones. However, the safety and the potential complications of this combined technique are not known yet. We present a patient who developed benign retroperitoneum after ES plus BOD with large-diameter balloon for re...
متن کاملCommon bile duct stones: if you can't sweep them, vacuum them!
Stone extraction from markedly dilated extrahepatic bile ducts can be challenging because of difficulty in achieving effective balloon apposition with the ductal wall. Studies examining stone extraction strategies in such cases are lacking. We describe this scenario in three patients and report a novel technique to overcome this technical difficulty. Patient #1 was a 64-year-old womanwith right...
