    Abstract:
    BACKGROUND: We report that an oblique-viewing endoscope facilitates endoscopic retrograde cholangiopancreatography (ERCP) in Billroth II reconstruction. With this endoscope, we carried out ERCP in Roux-en-Y reconstruction. METHODS: Fifteen patients with Roux-en-Y reconstruction were enrolled. Eleven of these patients had undergone gastrectomy, while Whipple's operation or choledochectomy had each been carried out in two patients. Among the 11 post-gastrectomy patients, eight had bile duct stones, and there was one case each of pancreatic abscess with chronic pancreatitis, bile duct obstruction due to gallbladder, or pancreatic cancer. The remaining four patients suffered from stenotic anastomosis of choledochojejunostomy. All procedures were carried out with an oblique-viewing endoscope. RESULTS: The papilla of Vater or anastomosis was reached in 10 patients. In these 10 patients, all planned procedures were completed. Endoscopic papillary balloon dilatation (EPBD) was carried out in three patients with bile duct stones. The remaining three patients with bile duct stones underwent sphincterotomy with tube stent placement, EPBD after sphincterotomy with biliary tube stent placement, and biliary tube stent placement, respectively. Pancreatic stent placement via the minor papilla was carried out in one patient with pancreatic abscess, and a biliary tube stent was introduced in the patient with gallbladder cancer. Two patients underwent cutting of a stenotic anastomosis with a needle knife, followed by balloon dilatation. None of the patients experienced any complications. CONCLUSION: The results appear to support the feasibility of using an oblique-viewing endoscope for ERCP in Roux-en-Y reconstruction. Further studies including a large population of patients should be planned to confirm these results.
