Peripancreatic fluid collection (PFC) due to pancreatic leakage is one of the significant complications arising following pancreatic surgery. Although endoscopic ultrasound (EUS)-guided drainage is less invasive than other methods in treating PFCs, it requires the drainage area to be in contact with the gastrointestinal tract accessible by the echoendoscope 1 . In patients with surgically altered anatomy, an oblique-viewing echoendoscope, which is mainly used for EUS-guided drainage, encounters technical difficulties in the jejunum. Recently, the usefulness of a forward-viewing echoendoscope in such cases has been reported 2 3 .

We experienced a case of afferent limb syndrome due to postoperative PFC at the pancreaticojejunal anastomosis following a modified Child resection in a 70-year-old man ( Fig. 1 ). As the fluid collection was remotely located from the stomach ( Fig. 2 ), and the afferent limb was in close proximity ( Fig. 3 ), EUS-guided drainage was attempted using a forward-viewing echoendoscope (TGF-UC260J; Olympus Optical, Tokyo, Japan) ( Video 1 ). Confirming the direction to reach the afferent limb was made relatively easy using the forward-viewing echoendoscope. Based on computed tomography (CT) findings, the target fluid collection could be confirmed by EUS observation where the scope was withdrawn a few centimeters from the choledochojejunal anastomosis. A 19G needle was used for puncture, a guidewire was placed, and the puncture site was dilated using a 4-mm tapered balloon. For double-wire indwelling, a double-lumen catheter was used, and the procedure was completed with placement of both internal and external stents. Immediately following the procedure, the patient showed symptom improvement, and 2 months later CT confirmed complete disappearance of the PFC ( Fig. 4 ).

Conventional EUS-guided drainage predominantly employs an oblique-viewing echoendoscope, which presents considerable challenges and perforation risks when intubating in the afferent limb. In contrast, the forward-viewing echoendoscope provides a superior and safer approach, offering precise echo-guided puncture determination.
