Introduction: Endoscopic ultrasound (EUS)-Directed transGastric ERCP (EDGE) is an advanced procedure utilized to enable pancreaticobiliary access in patients with Roux-en-Y gastric bypass anatomy. We hereby present a case of refractory pancreatic ascites from a persistent pancreatic duct (PD) leak treated with EDGE and transpapillary PD stenting.

Case Description/Methods: A 62-year-old white female with history of morbid obesity with Roux-en-Y gastric bypass and biliary pancreatitis with prior cholecystectomy was referred for refractory pancreatic ascites causing significant abdominal pain, poor oral intake and weight loss necessitating total parenteral nutrition. MRCP showed a PD leak in the body as cause for ascites (Fig. 1). After multidisciplinary team discussion, a staged EDGE for PD stenting was pursued. The gastric remnant was identified endosonographically through the jejunum, a 19G needle was advanced into it and 500 ml of saline was instilled to dilate the remnant. A 0.025 guidewire was coiled in the remnant and a 15mm by 10 mm cautery enhanced lumen apposing metal stent (LAMS) delivery system was used to create a jejunogastrostomy followed by LAMS deployment. LAMS was post dilated to 15 mm and ERCP was pursued after 10 days. During ERCP, PD leak at the body was confirmed on the pancreaticogram. A 5 Fr by 15 cm single pigtailed stent was deployed to bridge this leak. A large biliary sphincterotomy was also performed for a subjectively stenotic major papilla. Follow up CT scan after 1 month showed resolution of pancreatic ascites and repeat ERCP confirmed resolution of the PD leak. The biliary and pancreatic stents were removed. The jejunogastrostomy stent was removed after three months. She continues to remain asymptomatic and is tolerating a regular diet.

Discussion: This case demonstrates the successful use of EDGE procedure for management of refractory pancreatic ascites from a pancreatic duct leak. EDGE for pancreatic endotherapy in Roux-en-Y gastric bypass anatomy is a safe and effective alternative to more invasive laparoscopy or percutaneous gastrostomy access to the gastric remnant and should be considered in cases with ascites.
