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.
