Non-occlusive mesenteric ischemia: Diagnostic challenges and perspectives in the era of artificial intelligence

World J Gastroenterol. 2021 Jul 14;27(26):4088-4103. doi: 10.3748/wjg.v27.i26.4088.ABSTRACTAcute mesenteric ischemia (AMI) is a severe condition associated with poor prognosis, ultimately leading to death due to multiorgan failure. Several mechanisms may lead to AMI, and non-occlusive mesenteric ischemia (NOMI) represents a particular form of AMI. NOMI is prevalent in intensive care units in critically ill patients. In NOMI management, promptness and accuracy of diagnosis are paramount to achieve decisive treatment, but the last decades have been marked by failure to improve NOMI prognosis, due to lack of tools to detect this condition. While real-life diagnostic management relies on a combination of physical examination, several biomarkers, imaging, and endoscopy to detect the possibility of several grades of NOMI, research studies only focus on a few elements at a time. In the era of artificial intelligence (AI), which can aggregate thousands of variables in complex longitudinal models, the prospect of achieving accurate diagnosis through machine-learning-based algorithms may be sought. In the following work, we bring you a state-of-the-art literature review regarding NOMI, its presentation, its mechanics, and the pitfalls of routine work-up diagnostic exams including biomarkers, imaging, and endoscopy, we raise the perspectives of new biomarker exams, and finally we discuss what AI may add to the field, after summarizing what this technique encompasses.PMID:34326613 | PMC:...

ConclusionThe results of this study indicate that esophageal clearance may affect the treatment outcome of LF. Based on the findings of MII-pH, the longest reflux time and the number of refluxes longer than 5  min were important factors influencing the therapeutic effect, whereas based on the HRM, the DCI value was most important.

CONCLUSION: Gastrointestinal ischemia represents a rare manifestation of COVID-19. A high index of suspicion should lead to investigate this complication by CT scan, in the attempt to reduce its high mortality rate. Histology shows atypical feature of ischemia with important endotheliitis, probably linked to thrombotic microangiopathies.PMID:34539144 | PMC:PMC8409161 | DOI:10.3748/wjg.v27.i32.5448

Preoperative oral carbohydrate (POC) is an important element of the enhanced recovery after surgery protocol, but its effect on cirrhotic patients who tend to have abnormal gastric emptying remains unclarified. We investigated the influence of POC on gastric emptying and preprocedural well-being in cirrhotic patients.
