Exploratory investigation of virtual lesions in gastrointestinal endoscopy using a novel phase-shift method for three-dimensional shape measurement.

Accurate measurement of the size of lesions or distances between any two points during endoscopic examination of the gastrointestinal tract is difficult owing to the fisheye lens used in endoscopy. To overcome this issue, we developed a phase-shift method to measure three-dimensional (3D) data on a curved surface, which we present herein. Our system allows the creation of 3D shapes on a curved surface by the phase-shift method using a stripe pattern projected from a small projecting device to an object. For evaluation, 88 measurement points were inserted in porcine stomach tissue, attached to a half-pipe jig, with an inner radius of 21 mm. The accuracy and precision of the measurement data for our shape measurement system were compared with the data obtained using an Olympus STM6 measurement microscope. The accuracy of the path length of a simulated protruded lesion was evaluated using a plaster model of the curved stomach and graph paper. The difference in height measures between the measurement microscope and measurement system data was 0.24 mm for the 88 measurement points on the curved surface of the porcine stomach. The error in the path length measurement for a lesion on an underlying curved surface was <1% for a 10-mm lesion. The software was developed for the automated calculation of the major and minor diameters of each lesion. The accuracy of our measurement system could improve the accuracy of determining the size of lesions, whether protruded or depressed, regardless of the curvature of the underlying surface.

Immunoglobulin G4 -related gastrointestinal disease associated with type 1 autoimmune pancreatitis: A case report.

Immunoglobulin G4 (IgG4)-related diseaseis a systemic inflammatory condition of unknown etiology characterized by increases in serum IgG4 and in the number of IgG4-positive cells in affected tissues. One of the commonly involved locations is the pancreas; this condition is known as type 1 autoimmune pancreatitis (AIP). Type 1 AIP, which shows a biliary stricture in the intrapancreatic bile duct, can be misdiagnosed as a malignancy due to similar cholangiography findings and clinical presentation. In rare cases complicated by post-bulbar duodenal ulcers, differentiating between type 1 AIP and malignancies is even more difficult. An 81-year-old male was referred to our hospital for the treatment of a pancreatic head mass and obstructive jaundice. Serological and radiological findings were consistent with both type 1 AIP and a malignancy. Gastroduodenoscopy revealed a post-bulbar duodenal ulcer with endoscopic features that evoked malignant duodenal invasion. Although biopsies were negative for malignant cells, subsequent bleeding from the lesion suggested the progression of malignancy, which led to surgical resection. Pancreatoduodenectomy and pathological examination indicated that type 1 AIP was present. Simultaneously, the involvement of IgG4-related disease in the ulcerative lesion was suggested. To our knowledge, this is the first reported case of type 1 AIP complicated by post-bulbar duodenal ulcers, which was misdiagnosed as malignancy and considered an IgG4-related gastrointestinal disease associated with type 1 AIP.

Iron deposition in gastric black spots: Clinicopathological insights and NanoSuit-correlative light and electron microscopy analysis.

Objectives: Black spots (BSs) are lentiginous findings observed in the gastric body and fundus during upper gastrointestinal endoscopy and are predominantly seen in patients undergoing Helicobacter pylori eradication treatment. However, the detailed patient background and exact composition are poorly understood. This study aims to clarify the clinicopathological features of BSs, examine patient demographics, and use the NanoSuit-correlative light and electron microscopy (CLEM) method combined with scanning electron microscopy-energy dispersive X-ray spectroscopy for elemental analysis. Methods: Patients who underwent upper gastrointestinal endoscopy between 2017 and 2022 were included. Data on age, medications, blood tests, and H. pylori infection status were retrospectively gathered from medical records. Univariate analysis was conducted to examine BS presence, with results then used in a multivariate model to identify associated risk factors. Additionally, pathological specimens from patients with BSs were analyzed for elemental composition using the NanoSuit-CLEM method combined with scanning electronmicroscopy-energy dispersive X-ray spectroscopy. Results: An analysis of 6778 cases identified risk factors for BSs, including older age and using proton pump inhibitors, statins, corticosteroids, and antithrombotic drugs. Endoscopically, BSs correlated with higher gastric atrophy and lower active H. pylori infection. Iron deposition at BS sites was specifically identified using NanoSuit-CLEM. Conclusions: BSs on gastrointestinal endoscopy may indicate an absence of active H. pylori inflammation. The discovery of iron deposition within BSs using the NanoSuit-CLEM method has offered new insights into the possible causative factors and advances our understanding of the etiology of BSs, bringing us closer to unraveling the underlying mechanisms of their formation.

Dynamic endoscopic progression of gastrointestinal tract involvement in Langerhans cell histiocytosis: A pediatric case report.

Gastrointestinal tract involvement in Langerhans cell histiocytosis (LCH) is extremely rare, with limited documentation of endoscopic manifestations. We report a 19-month-old girl who presented with repeated diarrhea and bloody stools, accompanied by recurrent pulmonary infections, anemia, hypoproteinemia, thrombocytopenia, coagulopathy, and hepatosplenomegaly with lymphadenopathy. Initial treatment with antibacterial agents, mesalazine, thalidomide, and prednisone led to temporary improvement; however, the symptoms repeatedly relapsed. She underwent three digestive endoscopies, but until the third endoscopy, a definitive diagnosis of Langerhans cell histiocytosis was established through biopsy. While upper gastrointestinal tract findings were not significant, notable changes were observed in the colorectal region. A colonoscopy revealed progression from erythema to diffuse hyperemia and edema, with erythema, erosion, and superficial ulcers extending into the distal ileal mucosa. Genetic analysis identified a BRAF-V600E mutation. Following treatment with chemotherapy (vincristine and prednisone) and the BRAF inhibitor dabrafenib, the patient demonstrated significant clinical improvement within days. At the 1-year follow-up, the patient had normal bowel movements and a weight gain of 2.5 kg. Early gastrointestinal endoscopy with multiple biopsies in suspected children can facilitate early detection. Dabrafenib is a viable treatment option for Langerhans cell histiocytosis.

Clinical assessment of computed tomography for detecting ingested blister packs: A single-center retrospective study.

Objectives: Blister pack (BP) ingestion poses serious risks, such as gastrointestinal perforation, and accurate localization by computed tomography (CT) is a common practice. However, while it has been reported in vitro that CT visibility varies with the material type of BPs, there have been no reports on this variability in clinical settings. In this study, we investigated the CT detection rates of different BPs in clinical settings. Methods: This single-center retrospective study from 2010 to 2022 included patients who underwent endoscopic foreign body removal for BP ingestion. The patients were categorized into two groups for BP components, the polypropylene (PP) and the polyvinyl chloride (PVC)/polyvinylidene chloride (PVDC) groups. The primary outcome was the comparison of CT detection rates between the groups. We also evaluated whether the BPs contained tablets and analyzed their locations. Results: This study included 61 patients (15 in the PP group and 46 in the PVC/PVDC group). Detection rates were 97.8% for the PVC/PVDC group compared to 53.3% for the PP group, a significant difference (p < 0.01). No cases of BPs composed solely of PP were detected by CT. Blister packs were most commonly found in the upper thoracic esophagus. Conclusions: Even in a clinical setting, the detection rates of PVC and PVDC were higher than that of PP alone. Identifying PP without tablets has proven challenging in clinical. Considering the risk of perforation, these findings suggest that esophagogastroduodenoscopy may be necessary, even if CT detection is negative.

Establishment and validation of a risk prediction model for sarcopenia in gastrointestinal cancer patients: A systematic review and meta-analysis-based approach.

OBJECTIVE: The study aimed to develop a model to predict the risk of sarcopenia in gastrointestinal cancer patients. The goal was to identify these patients early and classify them into different risk categories based on their likelihood of developing sarcopenia. METHODS: This study evaluated risk factors for sarcopenia in patients with gastrointestinal cancers through a systematic review and meta-analysis. The natural logarithm of the combined risk estimate for each factor was used as a coefficient to assign scores within the model for risk prediction. Data from 270 patients with gastrointestinal cancers, collected between October 2023 and April 2024, was used to assess the predictive performance of the scoring model. RESULTS: The analysis included 17 studies that included 9405 patients with gastrointestinal cancers, out of which 4361 had sarcopenia. The model identified several significant predictors of sarcopenia, including age (OR = 2.45), sex (OR = 1.15), combined diabetes (OR = 2.02), neutrophil-to-lymphocyte ratio (NLR) category (OR = 1.61), TNM stage (OR = 1.61), and weight change (OR = 1.60). Model validation was performed using an external cohort through logistic regression, resulting in an area under the curve (AUC) of 0.773. This model attained a sensitivity of 0.714 and a specificity of 0.688 and ultimately selected 16.5 as the ideal critical risk score. Furthermore, an AUC of 0.770 was obtained from Bayesian model validation; the optimal critical risk score was determined to be 19.0, which corresponds to a sensitivity of 0.658 and a specificity of 0.847. CONCLUSIONS: The model of risk prediction developed through systematic review and meta-analysis demonstrates substantial for sarcopenia in patients with gastrointestinal cancers. Its clinical usability facilitates the screening of patients at high risk for sarcopenia.

Are We Enhancing Recovery After Neonatal Surgery? Assessment of Enhanced Recovery After Surgery Principles for Ostomy Takedown.

INTRODUCTION: Enhanced Recovery After Surgery (ERAS) guidelines in adults have demonstrated reduced complications, length of stay, and cost. However, neonatal ERAS studies are limited and translation of adult ERAS guidelines to neonates is challenging. Furthermore, the knowledge, perception, and practice of neonatal ERAS guidelines is largely unknown. Our aim is to address this practice gap by determining current practice of the 2020 neonatal intestinal surgery ERAS guidelines at our institution and evaluating postoperative outcomes. METHODS: A retrospective study was conducted of patients <1 y who underwent elective ostomy takedown at a single-center tertiary children's hospital between 2013 and 2023. A 13-point ERAS score was developed. Demographics, clinical course, pain management, nutrition, ERAS scores, and outcomes were analyzed using descriptive statistics, logistic and negative binomial regression. RESULTS: One hundred eighty-six patients met the inclusion criteria. At surgery, the median age was 124 d (interquartile range [IQR] 81-220) and median weight was 4360 g (IQR 2920-7200). The median ERAS score was 6 (IQR 5-7). The highest scores were for appropriate (97.9%) and timely (91.9%) prophylactic antibiotics, and the lowest for preventing intraoperative hypothermia (14.5%), limiting opioids (9.1%), and early enteral feeding postoperatively (24.7%). Surgical site infection occurred in 14.5% and median length of stay was 28 (IQR 5-127) d. CONCLUSIONS: Our institution's current practice of the 2020 neonatal intestinal surgery ERAS guidelines was poor. We identified opportunities for improvement including postoperative antibiotic administration, prevention of intraoperative hypothermia, nutrition, and pain management. Future studies will focus on implementation of neonatal ERAS guidelines at our institution and evaluation of adherence and outcomes.

Burden of gastrointestinal cancers among working-age population over past thirty years in China.

BACKGROUND: Although gastrointestinal (GI) cancers have been becoming a great public health concern in China, there is currently a lack of comprehensive literature on the overall burden and changing trends of GI cancers in the working-age population. AIM: To assess the burden of GI cancers and to examine the overall, age- and gender-specific trends among the working-age population in China from 1990 to 2019. METHODS: Data were extracted from the Global Burden of Disease Study 2019. The burden of GI cancers was indicated by incidence, mortality, disability-adjusted life-years (DALYs), age-standardized incidence rate (ASIR), age-standardized mortality rate, and age-standardized DALYs rate. Trends in the burden of GI cancers from 1990 to 2019 were examined using annual percent change and average annual percent change with Joinpoint regression models. RESULTS: For overall GI cancers, a declining trend was observed in the ASIR, age-standardized mortality rate, and age-standardized DALYs rate, with reductions of 0.74%, 2.23%, and 2.22%, respectively, from 1999 to 2019 in the Chinese working-age population. However, an increasing trend was observed in the ASIR for overall GI cancers from 2016-2019. The number of either incident cases, mortality cases, and DALYs was higher for colon/rectum cancer and liver cancer in younger participants but lower for esophageal, gallbladder, biliary tract, pancreatic, and stomach cancer among older subjects. Moreover, sex disparity in the GI cancers burden was also examined over 30 years. CONCLUSION: The total burden of GI cancers remained heavy among the working-age population in China, although declining trends were observed from 1999 to 2019. Disparities in the GI cancers burden existed between sexes, age groups, and cancer types. Population-based precision prevention strategies are needed to tackle GI cancers among working-age individuals, considering the age, sex, and cancer type disparities in China.

Two different mutational types of familial gastrointestinal stromal tumors: Two case reports.

BACKGROUND: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal (GI) tract, and cases of GISTs tend to be of the disseminated type, with a global incidence of 10 to 15 cases/million each year. The rarer familial GISTs, which often represent a population, differ in screening, diagnosis, and treatment. Familial GISTs include primary familial GISTs with predominantly KIT/PDGFRA mutations and wild-type GISTs. However, whether the same genetic family has different phenotypes has not been reported. CASE SUMMARY: We report two cases of rare GISTs in the same family: A male patient with the V561D mutation in exon 12 of the PDGFRA gene, who has been taking the targeted drug imatinib since undergoing surgery, and a female patient diagnosed with wild-type GIST, who has been taking imatinib for 3 years since undergoing surgery. The favorable prognosis of these patients during the 7-year follow-up period validates the accuracy of our treatment strategy, and we have refined the entire process of diagnosis and treatment of familial GISTs in order to better manage this rare familial disease. CONCLUSION: Different mutation types of familial GISTs in the same family are very rare, thus it is very important to make the correct diagnosis and treatment strategies according to the results of molecular detection for the management of familial GISTs.

Correlation between the neuroendocrine axis, microbial species, inflammatory response, and gastrointestinal symptoms in irritable bowel syndrome.

BACKGROUND: This study examines the complex relationships among the neuroendocrine axis, gut microbiome, inflammatory responses, and gastrointestinal symptoms in patients with irritable bowel syndrome (IBS). The findings provide new insights into the pathophysiology of IBS and suggest potential therapeutic targets for improving patient outcomes. AIM: To investigate the interactions between the neuroendocrine axis, gut microbiome, inflammation, and gastrointestinal symptoms in patients with IBS. METHODS: Patients diagnosed with IBS between January 2022 and January 2023 were selected for the study. Healthy individuals undergoing routine check-ups during the same period served as the control group. Data were collected on neuroendocrine hormone levels, gut microbiome profiles, inflammatory biomarkers, and gastrointestinal symptomatology to analyze their interrelations and their potential roles in IBS pathogenesis. RESULTS: IBS patients exhibited significant dysregulation of the neuroendocrine axis, with altered levels of cortisol, serotonin, and neuropeptides compared to healthy controls. The gut microbiome of IBS patients showed reduced diversity and specific alterations in bacterial genera, including Bifidobacterium, Lactobacillus, and Faecalibacterium, which were associated with neuroendocrine disturbances. Additionally, elevated levels of inflammatory markers, such as C-reactive protein, interleukin-6, and tumor necrosis factor-α, were observed and correlated with the severity of gastrointestinal symptoms like abdominal pain, bloating, and altered bowel habits. CONCLUSION: The findings suggest that targeting the neuroendocrine axis, gut microbiome, and inflammatory pathways may offer novel therapeutic strategies to alleviate symptoms and improve the quality of life in IBS patients.

Machine learning as a tool predicting short-term postoperative complications in Crohn's disease patients undergoing intestinal resection: What frontiers?

The recent study, "Predicting short-term major postoperative complications in intestinal resection for Crohn's disease: A machine learning-based study" investigated the predictive efficacy of a machine learning model for major postoperative complications within 30 days of surgery in Crohn's disease (CD) patients. Employing a random forest analysis and Shapley Additive Explanations, the study prioritizes factors such as preoperative nutritional status, operative time, and CD activity index. Despite the retrospective design's limitations, the model's robustness, with area under the curve values surpassing 0.8, highlights its clinical potential. The findings align with literature supporting preoperative nutritional therapy in inflammatory bowel diseases, emphasizing the importance of comprehensive assessment and optimization. While a significant advancement, further research is crucial for refining preoperative strategies in CD patients.

Advancing gastrointestinal stromal tumor management: The role of imagomics features in precision risk assessment.

BACKGROUND: Gastrointestinal stromal tumors (GISTs) vary widely in prognosis, and traditional pathological assessments often lack precision in risk stratification. Advanced imaging techniques, especially magnetic resonance imaging (MRI), offer potential improvements. This study investigates how MRI imagomics can enhance risk assessment and support personalized treatment for GIST patients. AIM: To assess the effectiveness of MRI imagomics in improving GIST risk stratification, addressing the limitations of traditional pathological assessments. METHODS: Analyzed clinical and MRI data from 132 GIST patients, categorizing them by tumor specifics and dividing into risk groups. Employed dimension reduction for optimal imagomics feature selection from diffusion-weighted imaging (DWI), T1-weighted imaging (T1WI), and contrast enhanced T1WI with fat saturation (CE-T1WI) fat suppress (fs) sequences. RESULTS: Age, lesion diameter, and mitotic figures significantly correlated with GIST risk, with DWI sequence features like sphericity and regional entropy showing high predictive accuracy. The combined T1WI and CE-T1WI fs model had the best predictive efficacy. In the test group, the DWI sequence model demonstrated an area under the curve (AUC) value of 0.960 with a sensitivity of 80.0% and a specificity of 100.0%. On the other hand, the combined performance of the T1WI and CE-T1WI fs models in the test group was the most robust, exhibiting an AUC value of 0.834, a sensitivity of 70.4%, and a specificity of 85.2%. CONCLUSION: MRI imagomics, particularly DWI and combined T1WI/CE-T1WI fs models, significantly enhance GIST risk stratification, supporting precise preoperative patient assessment and personalized treatment plans. The clinical implications are profound, enabling more accurate surgical strategy formulation and optimized treatment selection, thereby improving patient outcomes. Future research should focus on multicenter studies to validate these findings, integrate advanced imaging technologies like PET/MRI, and incorporate genetic factors to achieve a more comprehensive risk assessment.

The effect of intraoperative goal-directed fluid therapy in patients under anesthesia for gastrointestinal surgery.

BACKGROUND: Intraoperative fluid management is an important aspect of anesthesia management in gastrointestinal surgery. Intraoperative goal-directed fluid therapy (GDFT) is a method for optimizing a patient's physiological state by monitoring and regulating fluid input in real-time. AIM: To evaluate the efficacy of intraoperative GDFT in patients under anesthesia for gastrointestinal surgery. METHODS: This study utilized a retrospective comparative study design and included 60 patients who underwent gastrointestinal surgery at a hospital. The experimental group (GDFT group) and the control group, each comprising 30 patients, received intraoperative GDFT and traditional fluid management strategies, respectively. The effect of GDFT was evaluated by comparing postoperative recovery, complication rates, hospitalization time, and other indicators between the two patient groups. RESULTS: Intraoperative blood loss in the experimental and control groups was 296.64 ± 46.71 mL and 470.05 ± 73.26 mL (P < 0.001), and urine volume was 415.13 ± 96.72 mL and 239.15 ± 94.69 mL (P < 0.001), respectively. The postoperative recovery time was 5.44 ± 1.1 days for the experimental group compared to 7.59 ± 1.45 days (P < 0.001) for the control group. Hospitalization time for the experimental group was 10.87 ± 2.36 days vs 13.65 ± 3 days for the control group (P < 0.001). The visual analogue scale scores of the experimental and control groups at 24 h and 48 h post-surgery were 3.38 ± 0.79 and 4.51 ± 0.86, and 2.05 ± 0.57 and 3.51 ± 0.97 (P < 0.001), respectively. The cardiac output of the experimental and control groups was 5.99 ± 1.04 L/min and 4.88 ± 1.17 L/min, respectively, while the pulse pressure variability for these two groups was 10.87 ± 2.36% and 17.5 ± 3.21%, respectively. CONCLUSION: The application of GDFT in gastrointestinal surgery can significantly improve postoperative recovery, reduce the incidence of complications, and shorten hospital stays.

Effect of psychological nursing intervention on anxiety level and quality of life in patients with gastrointestinal peptic ulcer.

BACKGROUND: Peptic ulcer is a common gastrointestinal disease, and psychological intervention has an important influence on its occurrence and development. AIM: To investigate the effect of psychological nursing intervention on the anxiety level and quality of life of patients with gastrointestinal peptic ulcers. METHODS: Two groups of patients with peptic ulcer were selected from January to December 2012, with 60 cases in each group, and psychological nursing intervention and routine treatment were respectively performed. Psychological nursing interventions include cognitive behavioral therapy, psychological support and relaxation training. Self-rating anxiety scale (SAS) and quality of life questionnaire were used to evaluate the anxiety level and quality of life of patients before, during and after treatment. RESULTS: The SAS scores of the experimental group significantly decreased over the course of treatment, from 52.3 before treatment to 30.5 after treatment, while SAS scores of the control group did not change significantly. Meanwhile, the experimental group's quality of life score (SF-36) significantly improved over the course of treatment, from 65.2 to 85.2, while the control group remained stable. Further analysis showed that sex and age had no significant influence on the effect of psychotherapy. Both men and women, young and old, showed similar trends in anxiety relief and improved quality of life after treatment. CONCLUSION: Psychological nursing-based intervention program has a positive effect on the anxiety level and quality of life of patients with gastrointestinal peptic ulcer.

Left inferior phrenic arterial malformation mimicking gastric varices: A case report and review of literature.

BACKGROUND: Gastric submucosal arterial dilation resulting from splenic artery occlusion represents an exceedingly rare etiology of acute upper gastrointestinal bleeding (UGIB). Although endoscopy is a widely utilized diagnostic and therapeutic modality for gastrointestinal bleeding, it has limitations in detecting arterial abnormalities. CASE SUMMARY: This report presents a rare case of massive UGIB in a 57-year-old male with a tortuous left inferior phrenic artery accompanied by splenic artery occlusion. "Gastric varices" was identified during the patient's endoscopy one year before hemorrhage. Despite initial hemostasis by endoscopic clipping, the patient experienced massive rebleeding after one month, requiring intervention with transcatheter arterial embolization (TAE) to achieve hemostasis. CONCLUSION: This is the first case to report UGIB due to a tortuous left inferior phrenic artery. This case highlights the limitations of endoscopy in identifying arterial abnormalities and emphasizes the potential of TAE as a viable alternative for the management of arterial bleeding in the gastrointestinal tract.

Trend of robot-assisted surgery system in gastrointestinal and liver surgery: A bibliometric analysis.

BACKGROUND: Robot-assisted gastrointestinal and liver surgery has been an important development direction in the field of surgery in recent years and it is also one of the fastest developing and most concerning fields in surgical operations. AIM: To illustrate the major areas of research and forward-looking directions over the past twenty-six years. METHODS: Using the Web of Science Core Collection database, a comprehensive review of scholarly articles pertaining to robot-assisted gastrointestinal and liver surgery was researched out between 2000 and 2023. We used Citespace (Version 6.2.4) and Bibliometrix package (Version 4.3.0) to visualize the analysis of all publications including country, institutional affiliations, authors, and keywords. RESULTS: In total, 346 articles were retrieved. Surgical Endoscopy had with the largest number of publications and was cited in this field. The United States was a core research country in this field. Yonsei University was the most productive institution. The current focus of this field is on rectal surgery, long-term prognosis, perioperative management, previous surgical experience, and the learning curve. CONCLUSION: The scientific interest in robot-assisted gastrointestinal and liver surgery has experienced a significant rise since 1997. This study provides new perspectives and ideas for future research in this field.

Resuscitative endovascular balloon occlusion of the aorta (REBOA) for non-trauma patients in an urban hospital: a series of two cases.

Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is increasingly being used for temporary bleeding control in patients with trauma with non-compressible truncal hemorrhage (NCTH). In recent years, the technique is gaining popularity in postpartum hemorrhage and non-traumatic cardiac arrest, although still underutilized. In other surgical fields, however, there is not yet much awareness for the possible advantages of this technique. Consequently, for non-trauma indications, limited data are available. Methods: Description of the use of REBOA in two patients with hemorrhagic shock due to exsanguinating non-traumatic NCTH. Results: In the first case, REBOA was deployed at the emergency department in a patient in their 80s presenting with hemorrhagic shock due to a ruptured abdominal aortic aneurysm. Hemodynamic stability was obtained and a CT scan was subsequently performed for planning of endovascular aneurysm repair. After successful placement of the endograft, the REBOA catheter was deflated and removed. In the second case, REBOA was performed in a patient with shock due to iatrogenic epigastric artery bleeding after an umbilical hernia repair to prevent hemodynamic collapse and facilitate induction of anesthesia for definitive surgery. During laparotomy, blood pressure-guided intermittent aortic balloon occlusion was used to preserve perfusion of the abdominal organs. Patient made a full recovery. Conclusion: REBOA deployment was successful in achieving temporary hemorrhage control and hemodynamic stability in patients with non-traumatic NCTH. REBOA facilitated diagnostic work-up, transportation to the operating room and prevented hemodynamic collapse during definitive surgical repair. In the right patient and skilled hands, this relatively simple endovascular procedure could buy precious time and prove lifesaving in a variety of non-compressible hemorrhage.

Tuberculosis of gastrointestinal tract revealed by acute abdomen due to ileocecal perforation in an HIV-infected patient: A case report.

INTRODUCTION: Gastrointestinal tuberculosis (TB) is a rare condition, but it poses significant diagnostic and management challenges, especially in immunocompromised individuals. This case report discusses the diagnostic complexities and therapeutic strategies for managing gastrointestinal TB in an HIV-positive patient, emphasizing the importance of considering TB in differential diagnoses. CASE PRESENTATION: A 33-year-old male with no significant medical history presented with a five-day history of severe abdominal pain, initially epigastric and later localized to the right lower quadrant (RLQ). Physical examination revealed RLQ tenderness, and elevated inflammatory markers were observed in laboratory tests. Imaging studies suggested splenomegaly and signs consistent with acute appendicitis. Laparotomy uncovered a perforated cecal mass and diffuse white lesions across the small intestine. Histopathological analysis confirmed necrotizing granulomatous colitis, and PCR identified Mycobacterium tuberculosis (MTB). During hospitalization, the patient was diagnosed with HIV. CLINICAL DISCUSSION: This case underscores the diagnostic challenge of abdominal TB, particularly in HIV-infected patients where clinical presentation can mimic other conditions like Crohn's disease or appendicitis. Effective management requires timely surgical intervention, followed by appropriate anti-tuberculous and antiretroviral therapies. The multidisciplinary approach ensures comprehensive care and better patient outcomes. CONCLUSION: Effective recognition and diagnosis of gastrointestinal TB in HIV-positive patients are critical for successful treatment. This report highlights the necessity for heightened clinical suspicion and a collaborative approach in managing such complex cases, ultimately improving patient prognosis and care.

The Therapeutic Potential of Targeting Tumor Microenvironment and Modulation of Immunotherapy in Gastrointestinal Cancer.

Immunotherapy, as a novel treatment approach for various disorders, including cancers, is designed to either stimulate or suppress the immune system with high speci-ficity. The recent achievements of this therapy in clinical trials are set to transform tradi-tional treatment methods. Furthermore, it holds promise for enhancing the survival rates of patients suffering from both metastatic cancers and primary stages. Gastrointestinal Cancers (GI) account for 26% of global incidence and 35% of worldwide deaths. Treat-ment can be carried out using targeted immunotherapy in these cancers. If the tiers are superior, improvement could require more enterprise. On account that the function of immunotherapy in GI has been so promising, solely in sufferers with severe metastatic levels, within the literature, the immune checkpoint inhibitors in cancer immunotherapy of GI cancers, chimeric antigen receptor T-cell (vehicle-T), modulators of the tumor mi-croenvironment, and drug resistance mechanisms in immunotherapy as an effective treatment approach to GI cancers along with colon, pancreas, gastric, and esophageal cancers have been addressed. This review provides an overview of FDA-approved im-munotherapy drugs and ongoing preclinical developments. Additionally, we offer in-sights into the future of immunotherapy for GI cancer patients, addressing the associated challenges.
