ENDOSCOPIC ULTRASONOGRAPHY‐GUIDED FINE NEEDLE ASPIRATION BIOPSY IN A PATIENT WITH PRIOR BILLROTH II GASTRECTOMY

Endoscopic ultrasonography‐guided fine needle aspiration biopsy (EUS‐FNA) is a safe and accurate procedure for the diagnosis of pancreatic lesions. However, in general, surgically altered anatomy excluding Billroth I gastrectomy is considered a relative contraindication to EUS‐FNA. Herein, we described a successful case of EUS‐FNA in a patient with prior Billroth II gastrectomy. A 78‐year‐old man, who had previously undergone Billroth II gastrectomy for duodenal ulcer, undertook EUS‐FNA using a curved linear echoendoscope. An echoendoscope was advanced into the duodenum and EUS‐FNA could be carried out using a 22‐gauge needle without procedure‐related adverse event.
