This new nCLE criterion seems highly specific for the diagnosis of SCA. The visualization of this criterion could have a direct impact on the management of patients by avoiding unnecessary surgery or follow-up.Clinicaltrials.gov NCT01563133.

Based on this newly completed atlas of interpretation criteria, nCLE could facilitate the diagnosis of pancreatic cystic lesion types.

This article has an accompanying continuing medical education activity, also eligible for MOC credit, on page e19. Learning Objective: Upon completion of this CME activity successful learners will be able to (1) evaluate the probability of a venous thromboembolism (VTE) in patients with newly diagnosed pancreatic ductal adenocarcinoma (PDAC); (2) identify the risk factors for VTE in patients with PDAC; and (3) assess the impact of VTE on survival in patients with PDAC. Venous Thromboembolism and Pancreatic CancerThe BACAP-VTE Study : pancreatic cancer patients prospectively followed-up from time of enrollment until last visit or death 152 patients (20.79%) developed a VTE during a median follow-up of 19.3 months Patients developing VTE during follow-up had lower PFS (HR 1.74, 95%CI 1.19-2.54, P=.004) Patients developing VTE during follow-up had lower OS (HR 2.02, 95%CI 1.57-2.60, P<.001).

Background Needle-based confocal laser endomicroscopy (nCLE) enables observation of the inner wall of pancreatic cystic lesions (PCLs) during an endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). This study prospectively evaluated the diagnostic performance of nCLE for large, single, noncommunicating PCLs using surgical histopathology or EUS-FNA cytohistopathology as a reference diagnosis. Methods From April 2013 to March 2016, consecutive patients referred for EUS-FNA of indeterminate PCLs without evidence of malignancy or chronic pancreatitis were prospectively enrolled at five centers. EUS-FNA and nCLE were performed and cystic fluid was aspirated for cytohistopathological and carcinoembryonic antigen (CEA) analysis. The diagnostic performance of nCLE was assessed against the reference standard and compared with that of EUS and CEA. This study was registered on ClinicalTrials.gov (NCT01563133). Results 206 patients underwent nCLE and 78 PCLs (mean size 40 mm, range 20 – 110 mm) had reference diagnoses (53 premalignant and 25 benign PCLs). Post-procedure pancreatitis occurred in 1.3 % of the patients. nCLE was conclusive in 71 of the 78 cases (91 %). The sensitivies and specifities of nCLE for the diagnosis of serous cystadenoma, mucinous PCL, and premalignant PCL were all ≥ 0.95 (with 95 % confidence interval from 0.85 to 1.0). The AUROC was significantly larger for nCLE than for CEA or EUS. Conclusions nCLE had excellent diagnostic performance that surpassed that of CEA and EUS for the diagnosis of large, single, noncommunicating PCLs. The nCLE procedure should be considered in patients with indeterminate PCLs to ensure a more specific diagnosis.
