Endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) is an established technique for various pancreatic lesions. However, Roux-en-Y reconstruction (RY) is sometimes considered a relative contraindication of EUS-FNA.[1] Here, we present two successful cases of EUS-FNA using a new curved linear echoendoscope (CLE) in patients with RY.

Case 1: A 72-year-old man was admitted after total gastrectomy with RY for gastric cancer 10 years prior. Computed tomography (CT) revealed a low-density mass in the tail of the pancreas. EUS-FNA with standard CLE (GF-UCT260-AL5, Olympus, Tokyo, Japan) was attempted but failed to reach the afferent limb because of acute angulation. Instead, a new CLE (EG-580UT, Fujifilm, Tokyo, Japan) was carefully advanced to the afferent limb [Figure 1]. Pancreatic mass was well visualized, following successful and uneventful EUS-FNA using 22-gauge needle [Video 1].

Case 2: A 65-year-old man with a history of total gastrectomy and RY for gastric cancer 13 years prior was admitted. CT revealed a low-density mass with pseudocyst in the tail of the pancreas. After failed insertion of standard CLE, the new CLE was successfully advanced to the afferent limb. Subsequently, EUS-FNA was performed using 20-gauge needle without any complication [Video 2].




The majority of EUSs including FNAs are able to have a complete examination, if could reach the afferent limb even in cases of RY.[1] Low flexibility and low maneuverability due to restricted frontal endoscopic view of the standard echoendoscope make it challenging to reach the afferent limb.[2],[3] Recently, a forward-viewing echoendoscope has become available, however, the EUS view is quite narrow compared to the standard CLE. The new CLE has improved frontal endoscopic view and flexible scope tip [Figure 2]. Therefore, the new CLE enables a safe and reliable intubation, which might allow successful procedures for surgically altered anatomy.
