Even with advances in technology, it is still hard to distinguish between benign and malignant pancreatic tumours only from photographs. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA), a treatment with good accuracy and a low complication rate, is the method of choice for tissue collection to discriminate pancreatic lesions. In a meta-analysis, the combined sensitivity and specificity of EUS-FNA for determining the cause of solid pancreatic mass were 86.8% and 95.8%, respectively. Although patients with suspected pancreatic cancer demonstrate great diagnosis accuracy with EUS-FNA, the incidence of collecting ambiguous cytologic results is still up to 10.9%. When cytology from a EUS-FNA is inconclusive yet malignancy is highly suspected in the clinical presentation, an endosonographer has challenges.
