Known reasons for initial failure of stent placement were an inability to cannulate the normal bile duct in 12 patients with normal-appearing papilla, extensive tumor growth at the site of the papilla in 8 patients, and failure to attain the papilla in 1 individual with a Billroth type II gastric resection. After a second attempt, ERCP or PTC resulted in adequate drainage in 96 patients . Three sufferers did not undergo drainage because of misdiagnosed choledocholithiasis and endoscopic removal of an adenomatous polyp . There were technical failures in another three patients: failing of both ERCP and PTC , ERCP-linked bile-duct perforation that a crisis laparotomy with resection was performed , and sphincterotomy-connected hemorrhage, which halted the procedure .The team does not expect to create a vaccine but is hoping to inspire others. Wingreen is definitely a theoretical physicist, Levin is a theoretical Ndifon and ecologist is a graduate pupil learning theoretical biology. Our best wager is to express our ideas as clearly as we are able to and hope someone will see them interesting and perform the required experiments to verify or disprove them, Wingreen said.
