Background/Aims: Endoscopic visualization of the microscopic anatomy can facilitate the real-time diagnosis of pancreatobiliarydisorders and provide guidance for treatment. This study aimed to review the technique, image classification, and diagnosticperformance 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 thetechnique, image classification, diagnostic performance, ongoing research, and limitations. Results: Probe-based CLE differentiates malignant from benign biliary strictures (sensitivity, ≥89%; specificity, ≥61%). NeedlebasedCLE 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 interobservervariability are challenges for routine utilization. Conclusions: CLE reveals microscopic pancreatobiliary system anatomy with adequate specificity and sensitivity. Reducing costs andsimplifying image interpretation will promote utilization by advanced endoscopists.

Background/Aims Gastroparesis is a chronic gastrointestinal disorder that frequently presents with symptoms that are difficult to manage, necessitating frequent hospitalizations. We sought to determine the predictors of early readmission due to gastroparesis based on etiology. Methods We identified all adults discharged with a principal diagnosis of gastroparesis after hospitalization from the 2014 Nationwide Readmission Database. We compared etiology wise (diabetes, post-surgical, and idiopathic) early readmission. Multivariate regression analyses were performed to identify significant predictors of 30-day readmission. Results A total of 12 689 patients were identified, 30.7% diabetic, 2.6% post-surgical, and 66.7% were idiopathic. Patients with diabetic gastroparesis were more likely to be readmitted within 30 days than idiopathic (adjusted odds ratio [aOR], 0.81; 95% confidence interval [CI], 0.69-0.94) and post-surgical gastroparesis (aOR, 0.58; 95% CI, 0.34-0.98). Pyloroplasty was associated with less likelihood of 30-day readmission (aOR, 0.45; 95% CI, 0.20-0.97). In addition, male gender (aOR, 1.18; 95% CI, 1.02-1.37), modified Elixhauser comorbidity score ≥ 3 (aOR, 1.38; 95% CI, 1.18-1.61), chronic pain syndrome (aOR, 1.41; 95% CI, 1.11-1.78), younger (18-64 years) age (aOR, 1.64; 95% CI, 1.34-2.00), need for percutaneous endoscopic gastrostomy/jejunostomy tube (aOR, 2.06; 95% CI, 1.21-3.52), and need for total parenteral nutrition (aOR, 1.70; 95% CI, 1.24-2.35) were associated with increased risk of 30-day readmission. Conclusions One in 5 patients was readmitted with gastroparesis within 30 days. In the diabetic group, diabetes-related complications contributed to readmissions than gastroparesis. Pyloroplasty is associated with reduced early hospital readmission. Prospective studies are needed for validation of these results. (J Neurogastroenterol Motil 2021;27:408-418)
