Pancreas cyst fluid viscocity assesment in the diagnosis of mucinous cyts

We read with interest the article by Krishna et al1 about the use of EUS-guided needle-based confocal laser endomicroscopy (nCLE) in differentiating between mucinous and nonmucinous pancreatic cysts. They reported a cohort of patients with 16 mucinous and 13 nonmucinous pancreas cysts to assess the performance characteristics of EUS-guided nCLE, which was found to have a high accuracy. However, in our experience, nCLE is a very expensive evaluation method for daily practice. In differentiating between mucinous and nonmucinous pancreas cysts, determination of the viscosity of the cyst fluid may be useful.
