1Diagnostic approach to patients with acute idiopathic and recurrent pancreatitis,what should be done?显示文摘Acute recurrent pancreatitis (ARP) is a common clinical condition that may be difficult to diagnose. Endoscopic ultrasound (EUS) is proposed to be a safe first line test of choice in the majority of patients. When interventions are needed to remove biliary stones, evaluate sphincter of Oddi or pancreas divisum, endoscopic retrograde cholangiopancreatography (ERCP) is recommended. Magnetic resonance cholangiopancreatography (MRCP) can be a suitable alternative from a diagnostic standpoint although may not be widely available. Finally, genetic testing is increasingly used to detect certain mutations that are associated with this diagnosis.Mohammad Al-Haddad Michael B Wallace 2008World Journal of Gastroenterology2008,14,7:19
2Artificial intelligence in gastroenterology: A state-of-the-art review显示文摘The development of artificial intelligence(AI)has increased dramatically in the last 20 years,with clinical applications progressively being explored for most of the medical specialties.The field of gastroenterology and hepatology,substantially reliant on vast amounts of imaging studies,is not an exception.The clinical applications of AI systems in this field include the identification of premalignant or malignant lesions(e.g.,identification of dysplasia or esophageal adenocarcinoma in Barrett’s esophagus,pancreatic malignancies),detection of lesions(e.g.,polyp identification and classification,small-bowel bleeding lesion on capsule endoscopy,pancreatic cystic lesions),development of objective scoring systems for risk stratification,predicting disease prognosis or treatment response[e.g.,determining survival in patients post-resection of hepatocellular carcinoma),determining which patients with inflammatory bowel disease(IBD)will benefit from biologic therapy],or evaluation of metrics such as bowel preparation score or quality of endoscopic examination.The objective of this comprehensive review is to analyze the available AI-related studies pertaining to the entirety of the gastrointestinal tract,including the upper,middle and lower tracts;IBD;the hepatobiliary system;and the pancreas,discussing the findings and clinical applications,as well as outlining the current limitations and future directions in this field.Paul T Kröner Megan ML Engels Benjamin S Glicksberg Kipp W Johnson Obaie Mzaik Jeanin E van Hooft Michael B Wallace Hashem B El-Serag Chayakrit Krittanawong 2021World Journal of Gastroenterology2021,27,40:6

4Software for automated classification of probe-based confocal laser endomicroscopy videos of colorectal polyps显示文摘AIM:To support probe-based confocal laser endomi-croscopy (pCLE) diagnosis by designing software for the automated classification of colonic polyps. METHODS:Intravenous fluorescein pCLE imaging of colorectal lesions was performed on patients under-going screening and surveillance colonoscopies, followed by polypectomies. All resected specimens were reviewed by a reference gastrointestinal pathologist blinded to pCLE information. Histopathology was used as the criterion standard for the differentiation between neoplastic and non-neoplastic lesions. The pCLE video sequences, recorded for each polyp, were analyzed off-line by 2 expert endoscopists who were blinded to the endoscopic characteristics and histopathology. These pCLE videos, along with their histopathology diagnosis, were used to train the automated classification software which is a content-based image retrieval technique followed by k-nearest neighbor classification. The performance of the off-line diagnosis of pCLE videos established by the 2 expert endoscopists was compared with that of automated pCLE software classification. All evaluations were performed using leave-one-patient- out cross-validation to avoid bias. RESULTS:Colorectal lesions (135) were imaged in 71 patients. Based on histopathology, 93 of these 135 lesions were neoplastic and 42 were non-neoplastic. The study found no statistical significance for the difference between the performance of automated pCLE software classification (accuracy 89.6%, sensitivity 92.5%, specificity 83.3%, using leave-one-patient-out cross-validation) and the performance of the off-line diagnosis of pCLE videos established by the 2 expert endoscopists (accuracy 89.6%, sensitivity 91.4%, specificity 85.7%). There was very low power (< 6%) to detect the observed differences. The 95% confidence intervals for equivalence testing were:-0.073 to 0.073 for accuracy, -0.068 to 0.089 for sensitivity and -0.18 to 0.13 for specificity. The classification software proposed in this study is not a 'black box' but an informative tool based on the query by example model that produces, as intermediate results, visually similar annotated videos that are directly interpretable by the endoscopist. CONCLUSION:The proposed software for automated classification of pCLE videos of colonic polyps achieves high performance, comparable to that of off-line diagnosis of pCLE videos established by expert endoscopists.Barbara André Tom Vercauteren Anna M Buchner Murli Krishna Nicholas Ayache Michael B Wallace 2012World Journal of Gastroenterology2012,18,39:5
5Genetic interactions and modifi er genes in Hirschsprung's disease显示文摘Hirschsprung's disease is a congenital disorder that occurs in 1:5000 live births. It is characterised by an absence of enteric neurons along a variable region of the gastrointestinal tract. Hirschsprung's disease is classified as a multigenic disorder, because the same phenotype is associated with mutations in multiple distinct genes. Furthermore, the genetics of Hirschsprung's disease are highly complex and not strictly Mendelian. The phenotypic variability and incomplete penetrance observed in Hirschsprung' s disease also suggests the involvement of modifier genes. Here, we summarise the current knowledge of the genetics underlying Hirschsprung's disease based on human and animal studies, focusing on the principal causative genes, their interactions, and the role of modif ier genes.Adam S Wallace Richard B Anderson 2011World Journal of Gastroenterology2011,17,45:5
6Total pancreatectomy: Short- and long-term outcomes at a high-volume pancreas center显示文摘AIM To identify the current indications and outcomes of total pancreatectomy at a high-volume center. METHODS A single institutional retrospective study of patients undergoing total pancreatectomy from 1995 to 2014 was performed.RESULTS One hundred and three patients underwent totalpancreatectomy for indications including: Pancreatic ductal adenocarcinoma(n = 42, 40.8%), intraductal papillary mucinous neoplasms(n = 40, 38.8%), chronic pancreatitis(n = 8, 7.8%), pancreatic neuroendocrine tumors(n = 7, 6.8%), and miscellaneous(n = 6, 5.8%). The mean age was 66.2 years, and 59(57.3%) were female. Twenty-four patients(23.3%) underwent a laparoscopic total pancreatectomy. Splenic preservation and portal vein resection and reconstruction were performed in 24(23.3%) and 18 patients(17.5%), respectively. The 90 d major complications, readmission, and mortality rates were 32%, 17.5%, and 6.8% respectively. The 1-, 3-, 5-, and 7-year survival for patients with benign indications were 84%, 82%, 79.5%, and 75.9%, and for malignant indications were 64%, 40.4%, 34.7% and 30.9%, respectively.CONCLUSION Total pancreatectomy, including laparoscopic total pancreatectomy, appears to be an appropriate option for selected patients when treated at a high-volume pancreatic center and through a multispecialty approach.Hazem M Zakaria John A Stauffer Massimo Raimondo Timothy A Woodward Michael B Wallace Horacio J Asbun 2016World Journal of Gastrointestinal Surgery2016,8,9:3
