Endoscopic ultrasound-guided cutting of holes and deep biopsy for diagnosis of gastric infiltrative tumors and gastrointestinal submucosal tumors using a novel vertical diathermic loop

Figure 2 A case diagnosed with gastric linitis plastic. A: Endoscopic characteristics: thick and rigid gastric duplicature and a narrow cavity; B: The loop was placed on the targeted focus characterized by the obviously thick and rigid wall on the tumor, then the holes were cut; C: A biopsy forceps was poked into the holes to acquire the deep tissue samples under the guidance of EUS; D: The tissue specimen was then analysed histopathologically and shown to be gastric adenocarcinoma.
