Endoscopic ultrasound-guided transmural pancreatic duct drainage (EUS-PDD) has become an important alternative when transpapillary or transanastomotic pancreatic duct drainage is technically challenging 1 2. Recently, forward-viewing echoendoscope (FV-EUS) -guided drainage through the anastomotic site has been reported as a novel EUS-guided drainage technique; however, this approach has rarely been evaluated. A 69-year-old woman presented with epigastric discomfort 4 years after undergoing subtotal stomach-preserving pancreaticoduodenectomy for a pancreatic head neuroendocrine tumor (NET G1). Computed tomography demonstrated dilation of the main pancreatic duct (15 mm) indicating a pancreaticojejunostomy anastomotic stricture (PJAS; Fig. 1). Double-balloon endoscopy-assisted endoscopic retrograde cholangiopancreatography was attempted; however, the opening of the pancreatic duct could not be identified although the scope reached the anastomosis (Fig. 2). Therefore, EUS-guided recanalization using FV-EUS (TGF-UC260J, Olympus, Tokyo, Japan) was planned. With the aid of a guidewire placed near the anastomosis (Fig. 3 a) and external manual compression, FV-EUS was successfully advanced to the anastomotic site (Fig. 3 b, c). The dilated main pancreatic duct (9 mm) was punctured at the anastomotic site using a 19-gauge needle (Sonotip, Medi-Globe, Achenmühle, Germany), followed by contrast injection to confirm proper puncture (Fig. 4 a, b). A 0. 025-inch guidewire was advanced into the pancreatic duct (Fig. 4 c). The tract was dilated using a 4-mm REN balloon (KANEKA MEDIX, Osaka, Japan; Fig. 4 d), and finally, a 7-Fr, 7-cm plastic stent was deployed (Fig. 4 e, f, Video 1). The patient’s symptoms improved after the procedure, without adverse events. This case indicated that EUS-guided recanalization of the PJAS using FV-EUS was feasible and safe. Compared with conventional transmural EUS-PDD, EUS-guided recanalization may offer improved safety because the access route is through the PJA rather than through the abdominal cavity and pancreatic parenchyma, if FV-EUS can reach the anastomotic site 3 4 5. Further studies are required to clarify the safety, feasibility, and long-term outcomes of this technique. EndoscopyUCTNCodeTTT₁AS₂AI Article published online: 17 February 2026 © 2026.
