AI is rapidly gaining ground in various surgical fields worldwide. The current trajectory indicates that harnessing AI technologies can significantly improve patient care by reinforcing established practices and accelerating surgical innovation, offering a distinctive chance to explore potential advantages in providing health services to low- and middle-income countries (LMICs) globally.&lt;/p&gt;&lt;p&gt;Large language models hold immense promise in revolutionizing medical education and emerging as indispensable assets in surgical practice. Medical students and surgeons could easily access a wealth of educational materials and clinical insights presented intuitively, enriching their understanding and proficiency.&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt; AI technologies have demonstrated their effectiveness in tailoring surgical training, streamlining administrative duties, and creating practical and affordable simulation training programs tailored to the specific needs of diverse individuals.&lt;span&gt;&lt;sup&gt;3&lt;/sup&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;Integrating machine learning algorithms in areas like big data analysis, computer vision, and operative robotics promises to revolutionize surgical patient risk assessment, surgical treatment, and postoperative monitoring, potentially enhancing patient outcomes through reductions in morbidity and mortality.&lt;span&gt;&lt;sup&gt;4&lt;/sup&gt;&lt;/span&gt; More importantly, immediate intra-operative suggestions can assist surgeons in providing better evidence-based treatment to surgical patients.

This study aimed to investigate the impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection prior to gastroenterological cancer surgeries on postoperative complications using data from a nationwide database in Japan.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>Data on patients who underwent surgery for cancer including esophageal, gastric, colon, rectal, liver, and pancreatic cancer between July 1, 2019, and September 300, 2022, from real-world sources in Japan were analyzed. The association between preoperative SARS-CoV-2 infection and short-term postoperative outcomes was evaluated. A similar analysis stratified according to the interval from SARS-CoV-2 infection to surgery (&lt;4 vs. &gt;4 weeks) was conducted.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>In total, 60 604 patients were analyzed, and 227 (0.4%) patients were diagnosed with SARS-CoV-2 infection preoperatively. The median interval from SARS-CoV-2 infection to surgery was 25 days. Patients diagnosed with SARS-CoV-2 infection preoperatively had a significantly higher incidence of pneumonia (odds ratio: 2.05; 95% confidence interval: 1.05–3.74; <i>p</i> = 0.036) than those not diagnosed with SARS-CoV-2 infection based on the exact logistic regression analysis adjusted for the characteristics of the patients. A similar finding was observed in patients who had SARS-CoV-2 infection &lt;4 weeks before surgery.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Patients with a history of SARS-CoV-2 infection had a significantly higher incidence of pneumonia. This finding can be particularly valuable for countries that have implemented strict regulations in response to the COVID-19 pandemic and have lower SARS-CoV-2 infection-related mortality rates.</p>\u0000 </section>\u0000 </div>","PeriodicalId":8030,"journal":{"name":"Annals of Gastroenterological Surgery","volume":"8 5","pages":"942-951"},"PeriodicalIF":2.9,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ags3.12812","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141054193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
