Pancreatic rendezvous technique for treating a disconnected pancreatic duct syndrome in a patient with ansa pancreatica

We present the case of a 36-year-old patient with disconnected pancreatic duct syndrome following acute necrotizing alcoholic pancreatitis. As the patient experienced recurrent pancreatic collections, endoscopic retrograde cholangiopancreatography was performed to bridge the pancreatic disconnection and prevent further collection recurrence.

The initial step involved catheterizing the main pancreatic duct (MPD) via the major papilla ([Video 1]). Opacification of the MPD revealed the presence of an ansa pancreatica ([Fig. 1]), along with contrast leakage from the body portion of the MPD, confirming the disconnection. Owing to the significant angulation associated with the ansa pancreatica, the guidewire repeatedly ascended into the Santorini duct but failed to enter the body portion of the MPD ([Fig. 2]). A pancreatic stent was placed in the MPD, but migrated into the duodenum during the procedure.

Fig. 1 The first part of the procedure was to catheterize the main pancreatic duct (MPD).

As catheterization of the minor papilla was unsuccessful, we decided to perform a pancreatic rendezvous technique by catheterizing the Santorini duct from the major papilla. The guidewire was advanced through the minor papilla ([Fig. 3]). As the attempt to catheterize the minor papilla along with the previously inserted guidewire failed, it was then decided to capture the guidewire with a snare, and retrieve it through the working channel of the duodenoscope. The guidewire was then introduced into a sphincterotome, which was thus able to catheterize the minor papilla. This approach allowed the body portion of the MPD to be catheterized ([Fig. 4]), enabling the placement of a plastic stent to reach the disconnected area. The procedure was completed without complications.

Although the pancreatic rendezvous technique has been described previously [1], it is now most commonly performed via the endoscopic ultrasound approach [2] [3]. The technique described herein avoids the morbidity associated with endoscopic ultrasound-guided pancreatic puncture and appears to be preferable in cases involving altered anatomy, such as ansa pancreatica.
