Pneumonia caused by severe acute respiratory syndrome coronavirus 2 occasionally becomes severe and requires endotracheal intubation.Endotracheal intubation is usually performed using a laryngoscope;however,the operator needs to be in close proximity to the patient’s face during the procedure,which increases the risk of droplet exposure.Therefore,we simulated fiberoptic endotracheal intubation on a mannequin representing the patient,using an ultrathin flexible gastrointestinal endoscope as an alternative to the bronchoscope,in order to maintain distance from the patient during the procedure.We performed this procedure 10 times and measured the time required;the median procedure time was 6.4 s(interquartile range,5.7-8.1 s).The advantage of this method is the short procedure time and distance maintained from the patients.The flexible tip-steerable control and length of the gastrointestinal endoscope contributed to shortening the procedure time and maintaining distance from the patients.In addition,this method can handle difficult airways without risk of misplacement of the endotracheal tube.However,it is necessary to consider the risk of aerosol generation associated with this procedure.In the pandemic setting of coronavirus disease 2019,this approach may be useful when a gastrointestinal endoscopist is in charge of endotracheal intubation of patients with coronavirus disease 2019. 展开更多

BACKGROUND:It is controversial whether prophylactic endotracheal intubation(PEI)protects the airway before endoscopy in critically ill patients with upper gastrointestinal bleeding(UGIB).The study aimed to explore the predictive value of PEI for cardiopulmonary outcomes and identify high-risk patients with UGIB undergoing endoscopy.METHODS:Patients undergoing endoscopy for UGIB were retrospectively enrolled in the eICU Collaborative Research Database(eICU-CRD).The composite cardiopulmonary outcomes included aspiration,pneumonia,pulmonary edema,shock or hypotension,cardiac arrest,myocardial infarction,and arrhythmia.The incidence of cardiopulmonary outcomes within 48 h after endoscopy was compared between the PEI and non-PEI groups.Logistic regression analyses and propensity score matching analyses were performed to estimate effects of PEI on cardiopulmonary outcomes.Moreover,restricted cubic spline plots were used to assess for any threshold effects in the association between baseline variables and risk of cardiopulmonary outcomes(yes/no)in the PEI group.RESULTS:A total of 946 patients were divided into the PEI group(108/946,11.4%)and the non-PEI group(838/946,88.6%).After propensity score matching,the PEI group(n=50)had a higher incidence of cardiopulmonary outcomes(58.0%vs.30.3%,P=0.001).PEI was a risk factor for cardiopulmonary outcomes after adjusting for confounders(odds ratio[OR]3.176,95%confidence interval[95%CI]1.567-6.438,P=0.001).The subgroup analysis indicated the similar results.A shock index>0.77 was a predictor for cardiopulmonary outcomes in patients undergoing PEI(P=0.015).The probability of cardiopulmonary outcomes in the PEI group depended on the Charlson Comorbidity Index(OR 1.465,95%CI 1.079-1.989,P=0.014)and shock index>0.77(compared with shock index≤0.77[OR 2.981,95%CI 1.186-7.492,P=0.020,AUC=0.764]).CONCLUSION:PEI may be associated with cardiopulmonary outcomes in elderly and critically ill patients with UGIB undergoing endoscopy.Furthermore,a shock index greater than 0.77 could be used as a predictor of a worse prognosis in patients undergoing PEI. 展开更多

Experimental therapies targeting immune and stromal cells,such as mast cells,cancer-associated fibroblasts,dendritic cells,and tumor endothelial cells,in the treatment of gastrointestinal solid tumors pose new and complex surgical and medico-legal challenges.These innovative treatments require that informed consent not be limited to simple acceptance of the medical procedure,but instead reflect a true relational and cognitive process grounded in understanding,free choice,and the ability to revoke consent at any time.In particular,it is essential that the patient understands the experimental nature of the therapy,its development stage,potential benefits and risks,as well as the implications for their health and personal dignity.In the case of stromal cell-based treatments,which may exert complex immunomodulatory effects or activate angiogenic pathways that are not yet fully understood,patients must be made fully aware that they are participating in a non-standardized therapy whose outcomes,whether beneficial or harmful,cannot yet be predicted with certainty.This requires particularly careful medical communication,using simple yet scientifically accurate explanations delivered in appropriate language,along with a final verification of the patient’s actual understanding. 展开更多

Gastrointestinal(GI)cancers remain a leading cause of cancer-related morbidity and mortality worldwide.Artificial intelligence(AI),particularly machine learning and deep learning(DL),has shown promise in enhancing cancer detection,diagnosis,and prognostication.A narrative review of literature published from January 2015 to march 2025 was conducted using PubMed,Web of Science,and Scopus.Search terms included"gastrointestinal cancer","artificial intelligence","machine learning","deep learning","radiomics","multimodal detection"and"predictive modeling".Studies were included if they focused on clinically relevant AI applications in GI oncology.AI algorithms for GI cancer detection have achieved high performance across imaging modalities,with endoscopic DL systems reporting accuracies of 85%-97%for polyp detection and segmentation.Radiomics-based models have predicted molecular biomarkers such as programmed cell death ligand 2 expression with area under the curves up to 0.92.Large language models applied to radiology reports demonstrated diagnostic accuracy comparable to junior radiologists(78.9%vs 80.0%),though without incremental value when combined with human interpretation.Multimodal AI approaches integrating imaging,pathology,and clinical data show emerging potential for precision oncology.AI in GI oncology has reached clinically relevant accuracy levels in multiple diagnostic tasks,with multimodal approaches and predictive biomarker modeling offering new opportunities for personalized care.However,broader validation,integration into clinical workflows,and attention to ethical,legal,and social implications remain critical for widespread adoption. 展开更多

BACKGROUND Gastrointestinal(GI)tumors are among the most prevalent malignancies,and surgical intervention remains a primary treatment modality.However,the complexity of GI surgery often leads to prolonged recovery and high postoperative complication rates,which threaten patient safety and functional outcomes.Enhanced recovery after surgery(ERAS)principles have been shown to improve perioperative outcomes through evidence-based,multidisciplinary care pathways.Despite its widespread adoption,there is a paucity of research focusing specifically on optimizing ERAS-guided nursing processes in the post-anesthesia care unit(PACU)and evaluating its impact on perioperative safety in patients undergoing GI tumor surgery.This study aimed to investigate whether an ERASbased PACU nursing protocol could enhance recovery,reduce complications,and improve patient safety in this surgical population.AIM To explore the impact of optimizing the recovery room nursing process based on ERAS on the perioperative safety of patients with GI tumors.METHODS A total of 260 patients with GI tumors who underwent elective surgeries under general anesthesia in our hospital from August 2023 to August 2025 and were then observed in the recovery unit(PACU)were selected.They were randomly divided into the observation group(the PACU nursing process was optimized based on ERAS)and the control group(the conventional PACU nursing process was adopted)by the random number grouping method,with 130 cases in each group.The time of gastric tube removal,urinary catheter removal,defecation time,hospital stay,time of leaving the room after tube removal,retention time in the recovery room,occurrence of complications,satisfaction and readmission rate were compared between the two groups after entering the room.Compare the occurrence of adverse events in the PACU nursing process between the two groups.RESULTS The time of gastric tube removal,urinary catheter removal,defecation time,hospital stay,retention time in the recovery room,total incidence of complications and readmission rate in the observation group were significantly lower than those in the control group,and the satisfaction rate was higher than that in the control group(P<0.05).The occurrence of adverse events in the PACU nursing process in the observation group was lower than that in the control group(P<0.05).CONCLUSION Optimizing the PACU nursing process based on ERAS can effectively accelerate the recovery process of patients undergoing GI tumor surgery,reduce adverse events,improve nursing satisfaction,and at the same time,lower the incidence of adverse events in the PACU nursing process,providing a more refined management basis for clinical practice. 展开更多

Recent research has increasingly highlighted the potential oncogenic effects of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection within the gastrointestinal tract.Growing evidence suggests that SARS-CoV-2 may contribute to the development of gastrointestinal malignancies through several mechanisms,including sustained chronic inflammation,disruption of normal cellular homeostasis,and potential viral integration into host cells.These pathological processes have the potential to dysregulate critical cellular pathways,thereby promoting cancer development in vulnerable populations.A thorough understanding of how SARS-CoV-2 interacts with the development of gastro-intestinal cancer is essential for optimizing patient care and establishing compre-hensive,long-term monitoring protocols.This review highlighted the pressing need for ongoing research into the complex relationship between SARS-CoV-2 infection and the risk of gastrointestinal cancer. 展开更多

This editorial discusses Wang et al's article on familial gastrointestinal stromal tumors(GISTs).We read with great interest this article concerning the diagnosis,treatment,and post-treatment management of patients with familial GISTs.The actual incidence of GISTs may be underestimated due to diagnostic limitations and the long-term low-risk behavior of some GISTs.The molecular landscape of GISTs is primarily driven by mutations in the KIT and platelet-derived growth factor receptor alpha(PDGFRA)genes.A subset of GISTs without these mutations known as wild-type GISTs,may harbor other rare mutations,impacting their response to targeted therapies.Clinically,patients with GISTs present with nonspecific symptoms,often leading to delayed diagnosis.Genetic predispositions in familial GISTs provide insights into the genetic architecture and extragastrointestinal manifestations of GISTs.Management has evolved from surgical interventions to molecular-based therapies using tyrosine kinase inhibitors.The management of GISTs,especially in familial cases,requires a multidisciplinary approach.Cases of different gene mutations were reported in the same family,suggesting that incorporating genetic testing into routine clinical practice is crucial for the early identification of high-risk individuals and the implementation of tailored surveillance programs. 展开更多

Gastrointestinal(GI)cancers,which predominantly manifest in the stomach,colorectum,liver,esophagus,and pancreas,accounting for approximately 35%of global cancer-related mortality.The advent of liquid biopsy has introduced a pivotal diagnostic modality for the early identification of premalignant GI lesions and incipient cancers.This non-invasive technique not only facilitates prompt therapeutic intervention,but also serves as a critical adjunct in prognosticating the likelihood of tumor recurrence.The wealth of circulating exosomes present in body fluids is often enriched with proteins,lipids,microRNAs,and other RNAs derived from tumor cells.These specific cargo components are reflective of processes involved in GI tumorigenesis,tumor progression,and response to treatment.As such,they represent a group of promising biomarkers for aiding in the diagnosis of GI cancer.In this review,we delivered an exhaustive overview of the composition of exosomes and the pathways for cargo sorting within these vesicles.We laid out some of the clinical evidence that supported the utilization of exosomes as diagnostic biomarkers for GI cancers and discussed their potential for clinical application.Furthermore,we addressed the challenges encountered when harnessing exosomes as diagnostic and predictive instruments in the realm of GI cancers. 展开更多

Gastrointestinal stromal tumor(GIST)is a rare but an important clinical entity seen in our clinical practice.It is the most common mesenchymal tumor of the gastrointestinal tract and most common malignancy of the small intestine.Although the exact prevalence of GIST is not known,the incidence of GIST has been increasing.GISTs arise from interstitial cells of Cajal.Most of the GISTs occur due to mutation in c-kit gene or platelet derived growth factor receptor alpha gene.15%of GISTs do not have these mutations and they are called wildtype GISTs.Almost all GISTs express KIT receptor tyrosine kinase.Histologically,GISTs look like spindle cell tumors most of the time but they can be epitheloid or mixed type.The median size of GISTs varies from 2.7 cm to 8.9 cm.Clinically,patients with small GISTs remain asymptomatic but as the GIST size increases,patients present with various symptoms depending on the location of the GIST.Most of GISTs are located in the stomach or small bowel.Diagnosis is suspected on imaging and endoscopic studies,and confirmed by tissue acquisition with immunohistochemical staining.The aggressiveness of GISTs depends on the size,mitotic index and location.Surgical resection is the treatment of choice.But various endoscopic modalities of resection are increasingly being tried.Tyrosine kinase inhibitors are extremely useful in the management of large GISTs,unresectable GISTs and metastatic GISTs.Treatment options for metastatic GISTs also include radiotherapy,chemotherapy,hepatic artery embolization,chemoembolization and radiofrequency ablation. 展开更多

BACKGROUND The relationship between exercise and gastrointestinal(GI)health is complex and bidirectional.While moderate exercise generally promotes gut health by enhancing motility,reducing inflammation,and supporting microbial balance,intense or prolonged physical activity may exacerbate GI symptoms,particularly in individuals with preexisting digestive disorders.A deeper understanding of this interplay is essential for optimizing both exercise performance and GI well-being.AIM To synthesize current evidence on exercise-related GI disorders,exploring the prevalence,mechanisms,risk factors,and management strategies associated with exercise-induced GI symptoms.METHODS Following PRISMA guidelines,comprehensive searches of databases,including PubMed,Scopus,Web of Science,and EMBASE were conducted.Studies were included if they focused on exercise-induced GI disorders,encompassed randomized controlled trials,cohort studies,case-control studies,and cross-sectional designs,and addressed symptoms across various exercise modalities.Data were extracted and analyzed to identify patterns and implications for clinical and athletic practice.RESULTS A total of 231 studies met the inclusion criteria,highlighting both the benefits and risks of exercise on GI health.Regular moderate-intensity exercise,including activities such as walking,cycling,and yoga has been associated with improved GI function in conditions like gastroesophageal reflux disease,irritable bowel syndrome,inflammatory bowel disease,and constipation.These benefits are attributed to enhanced intestinal motility,reduced systemic inflammation,and improved gut barrier integrity.Additionally,exercise plays a role in regulating the gut-brain axis,with practices like yoga and Tai Chi demonstrating particular effectiveness in alleviating functional GI disorders.Conversely,high-intensity or prolonged exercise may contribute to symptoms such as nausea,diarrhea,and abdominal pain due to mechanisms like splanchnic hypoperfusion and increased intestinal permeability.Individual factors,including fitness level,dietary habits,hydration status,and underlying GI conditions,significantly influence the body’s response to exercise.CONCLUSION Moderate-intensity exercise is a beneficial and well-tolerated intervention for promoting GI health,whereas highintensity activities require careful monitoring,particularly in individuals with pre-existing GI disorders.Personalized exercise and dietary strategies are essential for balancing the benefits of physical activity with the risk of GI distress.Further research is needed to explore the long-term effects of exercise on gut microbiota composition and overall digestive health. 展开更多

Objective:There is currently no consensus on whether extra-gastrointestinal stromal tumors(EGISTs)and gastrointestinal stromal tumors(GISTs)are the same type of tumor,and whether the diagnosis and treatment of EGISTs can directly replicate the current diagnostic and treatment standards for GISTs.This study aims to further elucidate the clinical and pathological characteristics,diagnosis,treatment,and prognosis of EGISTs by analyzing the research results of domestic scholars in the field of EGISTs in the past decade.Methods:A review was conducted on original Chinese and English research articles published from 2013 to 2022 focusing on EGISTs.A descriptive approach was used to extract key information from the literature,including patient demographics,tumor location,tumor diameter,mitotic figures,risk stratification,immunohistochemical markers,cell type,and prognostic factors.The data were subjected to statistical analysis.Results:A total of 12 articles containing 780 EGIST patients were included.The male-to female incidence of EGISTs was 0.92꞉1.The most common sites of EGISTs were mesentery(30.96%),peritoneum or retroperitoneum(28.53%),omentum(20.32%),and pelvic cavity(12.52%).52.77%of EGISTs had tumor diameters greater than 10 cm,and the proportions of EGISTs with nuclear fission patterns greater than 5/50 high power field(HPF)and greater than 10/50 HPF were 51.24%and 26.11%,respectively.The proportion of high-risk EGISTs was 79.05%.The positive rates of immune markers CD117,CD34,and DOG-1 in EGISTs were 82.3%,69.0%,and 79.5%,respectively.The proportion of Ki-67>5%was 49.2%,and the proportion of Ki-67>10%was 24.8%.The proportions of EGISTs in spindle cells,epithelial cells,and mixed cells were 74.4%,14.8%,and 13.1%,respectively.The diameter of the tumor,resection method,risk level,Ki-67 index,mitotic counts,presence of rupture/bleeding/necrosis/peripheral tissue invasion/recurrence and metastasis,as well as the use of imatinib treatment after surgery were important factors affecting the prognosis of EGISTs.Conclusion:Current medical research is relatively well cognizant of GISTs with primary sites in the gastrointestinal tract.Compared with GISTs,EGISTs have large tumor diameters,high mitotic counts,a high percentage of high-risk grades,relatively unique molecular expression,and high aggressiveness.EGISTs differ from GISTs in clinicopathological characteristics.Whether EGISTs and GISTs share a common origin remains unclear.If they are distinct tumor entities,separate diagnostic and treatment guidelines for EGISTs should be established.If EGISTs are ultimately confirmed to be a special subtype of GISTs,then directly applying existing GIST-based standards to EGISTs may be inappropriate.A more scientific approach would involve subclassifying EGISTs based on anatomical location and then tailoring treatment strategies accordingly with reference to GIST guidelines. 展开更多

BACKGROUND Gastrointestinal bleeding(GIB)is a major cause of hospitalization worldwide.Patients with hematologic malignancies have a higher risk of GIB as a result of thrombocytopenia and platelet dysfunction.There is no consensus on the optimal platelet level that would be safe for endoscopic intervention,although a platelet level of>50×10^(9)/L was suggested based on expert opinion.There is a paucity of data on whether endoscopic intervention and the timing of endoscopy impacted the outcome of patients with hematologic malignancy and severe thrombocytopenia who experienced acute overt GIB.AIM To assess the safety of endoscopic intervention of inpatients with hematological malignancies and severe thrombocytopenia presenting with acute overt GIB.METHODS This is a single center retrospective study.The data was collected from the electronic health record from 2018 to 2020.Inpatients with hematologic malignancy who presented with acute overt GIB and platelet count≤50×10^(9)/L were included in the study.Outcomes included mortality,transfusion requirements,length of stay,intensive care unit admission and recurrent bleeding.A subgroup analysis was performed to compare the outcomes of urgent endoscopy within 24 hours of GIB vs endoscopy>24 hours.RESULTS A total of 76 patients were identified.The mean platelet count is 24.3 in the endoscopy arm and 14.6 in the conservative management arm.There was no statistically significant difference between patients who had endoscopy vs conservative management in 30-day(P=0.13)or 1 year(P=0.78)mortality,recurrent bleeding(P=0.68),transfusion of red blood cells(P=0.47),platelets(P=0.31),or length of stay(P=0.94).A subgroup analysis comparing urgent endoscopy within 24 hours compared with delayed endoscopy showed urgent endoscopy was not associated with improved 30-day or 1 year mortality(P=0.11 and 0.46,respectively)compared to routine endoscopy,but was associated with decreased recurrent bleeding in 30 days(P=0.01).CONCLUSION Medical supportive treatment without endoscopy could be considered as an alternative to endoscopic therapy for patients with hematologic malignancy complicated by severe thrombocytopenia and acute non-variceal GIB. 展开更多

Upper gastrointestinal(GI)endoscopy is considered an essential procedure in pediatric gastroenterology.It has evolved over many decades into a state where it plays a crucial role in providing diagnostic and therapeutic advantages across a broad spectrum of diseases.This review examines its role in diagnosing and managing common pediatric GI conditions,emphasizing notable advancements in techniques,clinical use,and future directions.We conducted a detailed literature survey using PubMed,Scopus,and Google Scholar,and English-language articles were reviewed.This review process included the latest articles,guidelines,and conference papers on pediatric and adult upper GI endoscopy.An upper GI endoscopy is imperative in diagnosing many pediatric GI diseases as it enables visualization of the gut mucosa,obtaining mucosal biopsies from suspicious areas or lesions for histological assessment,and selecting an effective management and follow-up plan.New advancements,including high-resolution endoscopy,narrow-band imaging,and confocal laser endomicroscopy,have revolutionized pediatric endoscopy by improving precision and reducing the need for invasive interventions.Furthermore,recent therapeutic developments in the field,such as endoscopic submucosal dissection and endoscopic mucosal resection,are now being utilized to treat preneoplastic lesions or refractory esophageal strictures.However,despite its usefulness,performing this procedure in children is challenging for various reasons,including the need for sedation,anesthesia,and smaller instrument sizes,the unavailability of trained staff,lack of training facilities,and the absence of dedicated endoscopy suites for children.In conclusion,pediatric upper GI endoscopy plays a pivotal role in pediatric gastroenterology,offering both therapeutic and diagnostic benefits.Progress in the field leads to the development of novel techniques that improve overall patient care,such as artificial intelligence in pattern recognition,which enhances lesion detection,predicts premalignant or pre-inflammatory areas,and minimizes investigator-related errors.Additionally,refining protocols and guidelines is essential to improve the safety,efficacy,and precision of upper GI endoscopy,ensuring the best possible care for children. 展开更多

Gastrointestinal hemangioma(GIH)is clinically rare,accounting for 7%-10%of benign gastrointestinal tumors and 0.5%of systemic hemangiomas.GIH can occur as either solitary or multiple lesions,with gastrointestinal bleeding as a significant clinical manifestation.Understanding the clinical and endoscopic features of GIH is essential for improving diagnostic accuracy,particularly through endoscopy and selective arteriography,which are highly effective in diagnosing GIH and preventing misdiagnosis and inappropriate treatment.Upon confirmed diagnosis,it is essential to thoroughly evaluate the patient's condition to determine the most suitable treatment modality—whether surgical,endoscopic,or minimally invasive intervention.The minimally invasive interventional partial embolization therapy using polyvinyl alcohol particles,proposed and implemented by Pospisilova et al,has achieved excellent clinical outcomes.This approach reduces surgical trauma and the inherent risks of traditional surgical treatments. 展开更多
