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. Georg Thieme Verlag KG Stuttgart. New York.
