Endoscopic retrograde cholangiopancreatography (ERCP) is difficult to perform in patients with a Billroth II anastomosis due to the anatomical alterations. This study evaluated retrospectively the efficacy and safety of endoscopic balloon dilatation after a partial infundibulotomy with a needle knife in patients who had undergone a Billroth II operation.
Between January 1, 2004 and December 31, 2005, 11 patients, who had undergone a prior Billroth II gastrectomy, underwent ERCP because of a suspicion of pancreatobiliary diseases. Infundibulotomy was performed using a needle knife sphincterotome. After a partial infundibulotomy, a dilation balloon was passed over a prepositioned guidewire and placed in the biliary orifice. Under endoscopic and fluoroscopic control, the balloon was then inflated with diluted contrast over a period of 1 to 2 minutes.
A total of 10 patients (7 male and 3 female) were enrolled in this study. Eight had common bile duct stones, 1 bile duct cancer, and 1 pancreatic cancer. The common bile duct was dilated by a balloon. The calculi were removed in 6 patients, and a common bile duct stent was implanted in two cases via endoscopy. No complications such as acute pancreatitis or apparent infections of the biliary tracts were encountered in these cases except for mild fever, temporary high serum levels of aminotransferase and amylase after ERCP in 3 cases. No severe bleeding or perforation occurred in patients undergoing balloon dilatation.
An infundibulotomy with balloon dilatation is a valuable alternative to endoscopic sphinterotomy in the treatment of patients with bile duct diseases, who have undergone prior Billroth II gastrectomies.
