Figure 2. Image of EUS-RFA: a 19-gauge needle probe is inserted into the pancreatic tumor under EUS-guidance (A); ablation is usually started in the right distal part of the tumor on the EUS image at the far end inside the lesion (B); echogenic bubbles are identified around the needle after ablation (C); and after needle withdrawal and reinsertion into the mass, RFA is repeated on the left side of the previous ablation site (D). EUS-RFA: Endoscopic ultrasound-guided radiofrequency ablation.
