Confocal Laser Endomicroscopy in the Diagnosis of Biliary and Pancreatic Disorders: A Systematic Analysis: Do Han Kim, Somashekar G. Krishna, Emmanuel Coronel, Paul T. Kröner, Herbert C. Wolfsen, Michael B. Wallace, Juan E. Corral; Clin Endosc 2022;55(2):197-207. Published online November 29, 2021; DOI: https://doi.org/10.5946/ce.2021.079

Background
/Aims: Endoscopic visualization of the microscopic anatomy can facilitate the real-time diagnosis of pancreatobiliary disorders and provide guidance for treatment. This study aimed to review the technique, image classification, and diagnostic performance of confocal laser endomicroscopy (CLE).
Methods
We conducted a systematic review of CLE in pancreatic and biliary ducts of humans, and have provided a narrative of the technique, image classification, diagnostic performance, ongoing research, and limitations.
Results
Probe-based CLE differentiates malignant from benign biliary strictures (sensitivity, ≥89%; specificity, ≥61%). Needlebased CLE differentiates mucinous from non-mucinous pancreatic cysts (sensitivity, 59%; specificity, ≥94%) and identifies dysplasia. Pancreatitis may develop in 2-7% of pancreatic cyst cases. Needle-based CLE has potential applications in adenocarcinoma, neuroendocrine tumors, and pancreatitis (chronic or autoimmune). Costs, catheter lifespan, endoscopist training, and interobserver variability are challenges for routine utilization.
Conclusions
CLE reveals microscopic pancreatobiliary system anatomy with adequate specificity and sensitivity. Reducing costs and simplifying image interpretation will promote utilization by advanced endoscopists.

Impact of Periampullary Diverticulum on ERCP Performance: A Matched Case-Control Study: Juan E. Corral, Omar Y. Mousa, Paul T. Kröner, Victoria Gomez, Frank J. Lukens; Clin Endosc 2019;52(1):65-71. Published online August 21, 2018; DOI: https://doi.org/10.5946/ce.2018.070

Background
/Aims: Periampullary diverticulum (PAD) is frequently encountered during endoscopic retrograde cholangiopancreatography (ERCP) and has been associated with stone formation in the bile duct. The effects of PAD on the ERCP procedure have been often debated. We aimed to compare the therapeutic success of ERCP between patients with PAD and matched controls.
Methods
We reviewed all ERCPs with findings of PAD in a national database (n=1,089) and compared them with age- and gendermatched controls in a 1:3 fashion (n=3,267). Demographics, endoscopic findings, visualization of main structures, and therapeutic success rates were compared between groups. Secondary analysis compared PAD cases and controls who had gallstone disease.
Results
The average cohort age was 68.4±14.3 years and 55.1% were male. ERCP success was similar in both groups, and no significant inter-group differences were found in the multivariate analysis. The presence of PAD did not affect the rates of sphincterotomy or visualization of main biliary structures. Secondary analysis showed similar success rates for gallstone removal between patients with PAD and controls.
Conclusions
PAD may not be considered a hinderance to ERCP success. Further research is needed to determine the best approach to cannulate the ampulla and provide endoscopic therapy for different subtypes of PAD.
