Salvage endoscopic ultrasound-guided rendezvous technique for disconnected pancreatic duct syndrome in a patient with severe acute pancreatitis
Disconnected pancreatic duct syndrome (DPDS) is characterized by extraductal leakage of pancreatic juice and destruction of tissue surrounding the pancreas . Many DPDS cases need surgical treatment . Transpapillary pancreatic stenting and endoscopic ultrasound (EUS)-guided transmural drainage of PD and walled-off necrosis (WON) are also reported to be effective for DPDS   . The EUS-guided rendezvous technique (EUS-RV) was shown to be effective as a salvage procedure to connect to the disruption directly when drainage procedures to treat DPDS proved ineffective.
A 60-year-old man suffered from severe pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP) for PD stenosis of the pancreatic head. He was transferred to our hospital for further treatment because his WON-related symptoms ([Fig. 1]) had worsened. We performed EUS-guided transmural drainage for the infected WON and percutaneous drainage for the abdominal effusion with a high amylase level. ERCP was performed for drainage to relieve the DPDS. Pancreatography showed only the proximal PD and extravasation of contrast medium in the WON ([Fig. 2a]). A nasocystic tube was placed in the WON via the PD because guidewire negotiation to the distal PD had failed ([Fig. 2b]). Pancreatic juice still leaked, so EUS-RV was performed to treat the DPDS ([Video 1]).
Video 1 Effective endoscopic ultrasound-guided rendezvous technique to connect to a pancreatic duct that had become disconnected due to severe acute pancreatitis.
The PD was punctured transgastrically by a 19-gauge needle (EZ shot 3 Plus; Olympus Medical, Tokyo, Japan), and a 0.025-inch hydrophilic guidewire was manipulated through the duodenal papilla along the nasocystic tube ([Fig. 3a]). The echoendoscope was switched to a duodenoscope. The guidewire was grasped and brought into the accessory channel. Another catheter was cannulated over the guidewire to the PD. Finally, an 8.5-Fr pancreatic stent (Olympus Medical) was placed across the disconnected PD ([Fig. 3b]). The exudate fluid was markedly reduced with external drainage, so the patient was transferred to the previous hospital 9 days after PD stenting without any complications.
