Techniques to facilitate ERCP with a conventional endoscope in patients with previous pancreatoduodenectomy.

There is little guidance on the performance of endoscopic retrograde cholangiopancreatography (ERCP) in patients with previous pancreatoduodenectomy. We reviewed techniques for ERCP with a conventional endoscope and assessed its value in 10 patients with previous pancreatoduodenectomy (15 ERCPs). After exploration of the surgical reconstruction, we used a front-viewing endoscope, and we used a small firm pillow under the abdomen and hand compression for preventing loop formation. Successful insertion to the ductal anastomoses and biliary cannulation were achieved in 13 / 15 procedures (87 %). In 6 procedures where we attempted pancreatic cannulation, we could not identify the pancreatojejunostomy, but after spraying contrast around the suspected location of the ductal anastomosis we obtained a pancreatogram in 4 / 6 procedures (67 %). Endoscopic biliary interventions were successful in 6 / 7 procedures (86 %). No complications were encountered. Use of appropriate techniques makes ERCP with a conventional endoscope feasible, effective, and safe in patients with previous pancreatoduodenectomy. Endoscopic therapy can be performed successfully in the bile duct, but has limited value regarding the pancreatic duct.
