Slow-pull and different conventional suction techniques in endoscopic ultrasound-guided fine-needle aspiration of pancreatic solid lesions using 22-gauge needles

Figure 1 Cytological assessments of the samples obtained by endoscopic ultrasound-guided fine-needle aspiration using four suction techniques (HE, orig. mag. × 40). A: The suction technique with a 20-mL syringe received a score of 2 for cellularity and a score of 3 for blood contamination; B: The suction technique with a 10-mL syringe received a score of 2 for cellularity and a score of 3 for blood contamination; C: The suction technique with a 5-mL syringe received a score of 3 for cellularity and a score of 2 for blood contamination; D: The slow-pull technique received a score of 3 for cellularity and a score of 1 for blood contamination.
