Abstract
Simple Summary With a five-year survival rate of only 3% for the majority of patients, pancreatic cancer is a global healthcare challenge. Radiomics and deep learning, two novel quantitative imaging methods that treat medical images as minable data instead of just pictures, have shown promise in advancing personalized management of pancreatic cancer through diagnosing precursor diseases, early detection, accurate diagnosis, and treatment personalization. Radiomics and deep learning methods aim to collect hidden information in medical images that is missed by conventional radiology practices through expanding the data search and comparing information across different patients. Both methods have been studied and applied in pancreatic cancer. In this review, we focus on the current progress of these two methods in pancreatic cancer and provide a comprehensive narrative review on the topic. With better regulation, enhanced workflow, and larger prospective patient datasets, radiomics and deep learning methods could show real hope in the battle against pancreatic cancer through personalized precision medicine. Abstract As the most lethal major cancer, pancreatic cancer is a global healthcare challenge. Personalized medicine utilizing cutting-edge multi-omics data holds potential for major breakthroughs in tackling this critical problem. Radiomics and deep learning, two trendy quantitative imaging methods that take advantage of data science and modern medical imaging, have shown increasing promise in advancing the precision management of pancreatic cancer via diagnosing of precursor diseases, early detection, accurate diagnosis, and treatment personalization and optimization. Radiomics employs manually-crafted features, while deep learning applies computer-generated automatic features. These two methods aim to mine hidden information in medical images that is missed by conventional radiology and gain insights by systematically comparing the quantitative image information across different patients in order to characterize unique imaging phenotypes. Both methods have been studied and applied in various pancreatic cancer clinical applications. In this review, we begin with an introduction to the clinical problems and the technology. After providing technical overviews of the two methods, this review focuses on the current progress of clinical applications in precancerous lesion diagnosis, pancreatic cancer detection and diagnosis, prognosis prediction, treatment stratification, and radiogenomics. The limitations of current studies and methods are discussed, along with future directions. With better standardization and optimization of the workflow from image acquisition to analysis and with larger and especially prospective high-quality datasets, radiomics and deep learning methods could show real hope in the battle against pancreatic cancer through big data-based high-precision personalization.

Abstract
BACKGROUND Surgical response of patients with symptomatic biliary colic but atypical findings of gallbladder polyps, hyper-dynamic gallbladder and otherwise negative biliary workup are underrepresented in the literature from community practice. METHODS A clinical outcome study with a retrospective design compared the short term and long term symptomatic improvement reported by patients with pre-operatively diagnosed biliary dyskinesia to all other biliary colic patients with atypical pre-operative diagnoses. All patients underwent surgery at Meridian Surgery Center from the years 2010-2017.600 patients were reviewed for biliary dyskinesia, gallbladder polyps, hyper-dynamic gallbladder and negative workup. RESULTS Short term and long term results were compiled from a total 182 patients. Short term response rates were assessed from 74 biliary dyskinesia, 40 hyperdynamic, 23 gallbladder polyps, and 45 negative workup patients. Long term responses were received from 19 biliary dyskinesia patients, 11 hyperdynamic patients, 9 polyp patients, and 7 negative workup patients. Long term improvement among biliary dyskinesia patients was 84%, and 83% among patients with atypical findings, representing a long term drop in symptoms. There is no significant difference between symptom recovery of patients with biliary dyskinesia and those with another atypical diagnosis: hyper-dynamic (82%), polyps (89%), negative workup (57%). CONCLUSION These results allow us to conclude that there is a comparable biliary colic improvement between biliary dyskinesia, gallbladder polyps, hyper-dynamic gallbladder and negative workup patients after cholecystectomy in both short term and long term follow up.
