Impacted and Fractured Biliary Basket: A Second Basket Rescue Technique
A 59-year-old woman was treated with ERCP, ES, and biliary plastic stent, for large and multiple common bile duct stones. During a second ERCP basket extraction was impacted with a round entrapped stone. The basket handle was cut off; a metal sheath of extraendoscopic lithotriptor was advanced over the basket. The mechanical lithotripsy was complicated with basket traction wires fracturing, wit...
متن کاملBasket, Flat Plumbing and Flat Plumbing Basket Numbers of Links
We define the basket number, the flat plumbing number and the flat plumbing basket number of a link. Then we provide some upperbounds for these plumbing numbers by using Seifert’s algorithm. We study the relation between these plumbing numbers and the genera of links.
