A 33-year-old male, case of acute necrotizing pancreatitis, presented with a pancreatopleural fistula with massive right pleural effusion. There was persistent output from an intercostal drain in the right thorax. Magnetic resonance cholangiopancreatography showed pancreas divisum type II with leak from the tail of the pancreas tracking to the right pleura, with collection in the region of the head of the pancreas [Figure 1]. Endoscopic retrograde pancreatography was attempted twice through the minor papilla but failed despite precut sphincterotomy [Figure 2]a. EUS-guided rendezvous (RV) was considered due to failure of access. EUS showed 1.7-mm pancreatic duct (PD) in the body of the pancreas [Figure 2]b, which was punctured using a 22G FNA needle [Figure 2]c. After contrast injection, 0.018” guidewire was passed across into the duodenum [Figure 2]d. Scope was changed to duodenoscope while maintaining guidewire position. The guidewire was drawn out through the duodenoscope using rat-tooth forceps. An endoscopic retrograde cholangiopancreatography cannula was then passed across into the PD and guidewire was changed to 0.025”, passed till the tail of the pancreas. Pancreatogram showed leak from the tail of the pancreas [Figure 3]. After sphincterotomy, 5 Fr pancreatic stent placed across the leak in tail region [Figure 4]. Intercostal drain output reduced to nil by day 7 and was removed on day 10. He was discharged after nutritional rehabilitation on day 14 after procedure. | Figure 1: Magnetic resonance cholangiopancreatography showing pancreas divisum with leak from the tail of the pancreas with collection in the region of the neck of the pancreas

Endoscopic pancreatic stent placement remains the mainstay of therapy for symptomatic PD obstruction or leakage.[1] The first report of EUS-guided pancreatic access with RV was reported in 2002.[2] EUS RV is more challenging than transmural drainage due to difficulty passing guidewire across the papilla and exchange to a duodenoscope.[3] The technical success of anterograde pancreatic ductal interventions is 87%, including RV and anterograde stenting. Puncture in undilated duct is more challenging, with difficulty gaining access and passing guidewire across the papilla. Only one case report describes EUS RV in a patient with undilated PD and chronic pancreatitis with pancreatic ascites.[4] We were able to achieve access of the undilated PD in our patient with EUS guidance and subsequently bridge the pancreatic leak.
