Background: Missed early gastric cancer (MEGC) is prevalent during esophagogastroduodenoscopy (EGD), which is the first-line recommended strategy for detecting early gastric cancer (EGC). Hence, we explored the risk factors for MEGC and different types of MEGC, based on the endoscopic resected population. Methods: This retrospective, case–control study was conducted at Nanjing Drum Tower Hospital (NJDTH). We included patients who were diagnosed with EGC during screening EGD, underwent endoscopic resection, and were confirmed by postoperative pathology at the NJDTH from January 2014 to December 2021, and classified them into different types according to the different root causes of misses. Univariable, multivariable, subgroup and propensity score analyses were used to explore the risk factors for MEGC and different types of MEGC. Results: A total of 447 patients, comprising 345 with initially detected early gastric cancer (IDEGC) and 102 with MEGC, were included in this study. Larger size (≥ 1 cm) (OR 0.45, 95% CI 0.27–0.74, P = 0.002) and invasion depth of submucosa (OR 0.26, 95% CI 0.10–0.69, P = 0.007) were negatively associated with MEGC. Use of sedation (OR 0.32, 95% CI 0.20–0.52, P < 0.001) and longer observation time (OR 0.60, 95% CI 0.37–0.96, P = 0.034) exhibited protective effect on MEGC. Conclusions: Smaller and more superficial EGC lesions are more susceptible to misdiagnosis. The use of sedation and prolonged observation time during EGD could help reduce the occurrence of MEGC.

Upper gastrointestinal bleeding (UGIB) is a significant concern in children, contributing to 6–20% of cases in pediatric intensive care units. This study evaluates the roles of Helicobacter pylori (H. pylori) infection and non-steroidal anti-inflammatory drug (NSAID) usage in the etiology of UGIB in children, with a particular focus on trends observed during the COVID-19 pandemic. We conducted a retrospective analysis of 103 pediatric patients who underwent esophagogastroduodenoscopy (EGD) for UGIB between January 2015 and December 2023. Of these, 88 patients were included in the final analysis, where the source of bleeding was successfully identified. Hematemesis was the most common presentation, and the source of bleeding was identified in 85.43% of cases. The prevalence of H. pylori infection remained stable across the pre-pandemic (39.7%) and post-pandemic (36.7%) periods. However, NSAID usage increased nearly threefold during the pandemic, with 36.7% of post-pandemic UGIB cases associated with NSAID use, compared to 12.1% pre-pandemic. These findings underscore the significant roles of H. pylori and NSAID use in pediatric UGIB, with a notable increase in NSAID-related cases during the pandemic. [ABSTRACT FROM AUTHOR]

Introduction: The role of routine preoperative esophagogastroduodenoscopy (EGD) in bariatric surgery candidates is controversial. This study compares preoperative EGD outcomes with patient-reported gastroesophageal reflux disease (GERD) symptoms to determine if a case-based EGD is appropriate. Patients and Methods: A prospective cohort study was conducted from April 2022 through September 2023 in Mashhad, Iran. All patients underwent EGD. To assess GERD symptoms, we used the GERD-Health Related Quality of Life questionnaire. Patients were categorized into two groups: the asymptomatic group (GERD-HRQL = 0) and the symptomatic group (GERD-HRQL > 0). Results: A total of 165 patients were included, out of which 133 (80.6%) were in the symptomatic group and 32 (19.4%) were in the asymptomatic group. Esophagitis was present in 41 (24.8%) patients. There was no significant difference in the frequency of esophagitis (18.8% vs. 26.3%, p-value = 0.37), hiatal hernia (18.8% vs. 18.8%, p-value = 1.00), gastritis (56.3% vs. 63.9%, p-value = 0.42), and H. pylori infection (9.4% vs. 12.0%, p-value = 1.00) between the asymptomatic and symptomatic groups, respectively. None of the demographic factors or comorbidities of asymptomatic patients were associated with esophagitis, except for hiatal hernia (OR = 7.67, 95% CI 3.01–19.53, p-value < 0.001). Receiver operating characteristic (ROC) analysis showed that the GERD-HRQL total scores, as well as the heartburn and regurgitation subscales, were poor predictors of esophagitis (AUC 0.57, 0.51, and 0.56, respectively). Conclusion: EGD findings were not associated with GERD symptoms in candidates for bariatric surgery. [ABSTRACT FROM AUTHOR]

Introduction: Esophagogastroduodenoscopy (EGD) requires adequate air infusion. However, cases of poor gastrointestinal wall extension due to frequent eructation have been reported. Sufficient gastrointestinal wall extension can be achieved by applying cricoid pressure during EGD. Herein, we evaluated the frequency of cases with poor gastrointestinal wall extension and the efficacy and safety of applying cricoid pressure during EGD. Methods: This interventional study included patients who underwent EGD between January 2020 and December 2020 at the JA Akita Koseiren Yuri Kumiai General Hospital. Cases wherein folds of the greater curvature of the upper gastric body were not sufficiently extended during EGD were considered to have poor gastrointestinal wall extension. In such cases, air infusion was performed while applying cricoid pressure. This procedure was considered effective when gastric wall extension was achieved. Results: A total of 2,000 patients were enrolled and underwent upper gastrointestinal endoscopy; however, five were excluded because of upper gastrointestinal tract stenosis. Observation of gastric wall extension of the greater curvature in the upper gastric body with normal air insufflation was difficult in 113 (5.7%) cases. Applying cricoid pressure was effective in 93 (82.3%) patients with poor gastric wall extension. Sufficient gastric wall extension was achieved within an average of 12.8 s in cases where cricoid pressure application was effective. No adverse events were associated with cricoid pressure application. Conclusions: Cricoid pressure application for patients with poor gastric wall extension during EGD is useful for ensuring a sufficient field of view during observation of the gastric body.

Background: Primary gastrointestinal follicular lymphoma is a subtype of follicular lymphoma that originates directly from the gastrointestinal tract. Pathologically, it exhibits substantial similarities with the secondary gastrointestinal involvement observed in nodal follicular lymphoma. However, primary gastrointestinal follicular lymphoma presents clinically distinct features, necessitating divergent considerations in treatment selection compared with nodal follicular lymphoma. Areas covered: This narrative review focused on recent articles (2018–2023) regarding the long-term prognosis and treatment options for gastrointestinal follicular lymphoma. In addition, a brief overview of gastrointestinal follicular lymphomas is provided. Expert opinion: Patients with primary gastrointestinal follicular lymphoma often present with a low tumor burden. Lymphoma lesions typically remain asymptomatic for several years or may undergo spontaneous regression without immediate treatment. Therefore, a 'watch and wait' approach is justified. Conversely, when large tumor masses are identified in the gastrointestinal tract, the potential for tumor bleeding or intestinal obstruction requires timely therapeutic interventions.

Purpose of reviewWhile guidelines exist for the evaluation and management of esophageal dysphagia in the general population, dysphagia disproportionately affects the elderly. In this article, we reviewed the literature on evaluating esophageal dysphagia in elderly patients and proposed a diagnostic algorithm based on this evidence.Recent findingsIn older patients, dysphagia is often well compensated for by altered eating habits and physiologic changes, underreported by patients, and missed by healthcare providers. Once identified, dysphagia should be differentiated into oropharyngeal and esophageal dysphagia to guide diagnostic workup. For esophageal dysphagia, this review proposes starting with endoscopy with biopsies, given its relative safety even in older patients and potential for interventional therapy. If endoscopy shows a structural or mechanical cause, then further cross-sectional imaging should be considered to assess for extrinsic compression, and same session endoscopic dilation should be considered for strictures. If biopsies and endoscopy are normal, then esophageal dysmotility is more likely, and high-resolution manometry and additional workup should be performed following the updated Chicago Classification. Even after diagnosis of the root cause, complications including malnutrition and aspiration pneumonia should also be assessed and monitored, as they both result from and can further contribute to dysphagia. The successful evaluation of esophageal dysphagia in elderly patients requires a thorough, standardized approach to collecting a history, selection of appropriate diagnostic workup, and assessment of risk of potential complications, including malnutrition and aspiration.

Background/Aims To overcome the technical limitations of classic endoscopic resection for gastric gastrointestinal stromal tumors (GISTs), various methods have been developed. In this study, we examined the role and feasibility of clip-and-cut procedures (clip-and-cut endoscopic full-thickness resection [cc-EFTR]) for gastric GISTs. Methods Medical records of 83 patients diagnosed with GISTs after endoscopic resection between 2005 and 2021 were retrospectively reviewed. Moreover, clinical characteristics and outcomes were analyzed. Results Endoscopic submucosal dissection (ESD) and cc-EFTR were performed in 51 and 32 patients, respectively. The GISTs were detected in the upper third of the stomach for ESD (52.9%) and cc-EFTR (90.6%). Within the cc-EFTR group, a majority of GISTs were located in the deep muscularis propria or serosal layer, accounting for 96.9%, as opposed to those in the ESD group (45.1%). The R0 resection rates were 51.0% and 84.4% in the ESD and cc-EFTR groups, respectively. Seven (8.4%) patients required surgical treatment (six patients underwent ESD and one underwent cc-EFTR,) due to residual tumor (n=5) and post-procedure adverse events (n=2). Patients undergoing R0 or R1 resection did not experience recurrence during a median 14-month follow-up period, except for one patient in the ESD group. Conclusions cc-EFTR displayed a high R0 resection rate; therefore, it is a safe and effective therapeutic option for small gastric GISTs.

Background/Aims Nonagenarians will purportedly account for 10% of the United States population by 2050. However, no studies have assessed the outcomes of nonvariceal upper gastrointestinal bleeding (NVUGIB) in this age group. Methods The National Inpatient Sample database between 2016 and 2020 was used to compare the clinical outcomes of NVUGIB in nonagenarians and octogenarians and evaluate predictors of mortality and the use of esophagogastroduodenoscopy (EGD). Results Nonagenarians had higher in-hospital mortality than that of octogenarians (4% vs. 3%, p

Aim: to evaluate, using the “GastroPanel®”, the frequency of detection of H. pylori infection and associated gastric diseases among doctors and medical staff of the National Medical Research Radiological Centre of the Ministry of Health of the Russian Federation, Moscow.Materials and methods. Employees of three branches of the National Medical Research Radiological Centre (n = 434, mean age — 48.5 ± 0.6 years) were examined using laboratory tests “GastroPanel®” (Biohit Oyj, Finland). The test results make it possible to identify infection of the stomach with H. pylori, hypo- and hyperacid conditions, as well as atrophic gastritis of the antrum and body of the stomach, as its precancerous conditions. Esophagogastroduodenoscopy (EGDS) for suspected atrophic gastritis was performed with an Olympus GIF-HQ190 video endoscope (Japan) in a narrow-spectrum mode with close focus (NBI Dual Focus).Results. The absence of pathological signs detected by “GastroPanel®” was established in 23.3 % of cases, hyperacid state — in 18.4 %, and hypoacid state — in 5.2 %. These disorders are classified as functional. Consequently, the conditional norm in total was identified in 46.9 % of observations. An increased level of antibodies to H. pylori was found in 43.3 % of those examined. Atrophic gastritis in the body of the stomach according to the results of the “GastroPanel®” was detected in 4.8 % of cases (median age — 59 years), in the antrum (or increased secretion of hydrochloric acid) — also in 4.8 % of cases (median age — 52 years). Within two months after laboratory diagnostics, EGDS was performed for 10 out of 15 patients examined at the P. Hertsen Moscow Oncology Research Institute in whom, based on the results of the “GastroPanel®”, the presence of atrophic gastritis in the antrum (or increased secretion of hydrochloric acid) was suspected. In 6 out of 10 cases, atrophic gastritis of the antrum was confirmed (in two of them, the atrophy extended to the body of the stomach and was assessed as severe). Of the 11 people with the “GastroPanel®” conclusion “Atrophic gastritis of the body of the stomach,” an endoscopic examination was carried out in 7 persons, and in all these cases the diagnosis was confirmed, and in two people the conclusion was made of severe atrophic pangastritis.Conclusion. “GastroPanel®” confirmed its high significance in identifying H. pylori infection and precancerous atrophic changes in the gastric mucosa. Regarding the occupational risks of infection among medical workers, we consider it advisable to conduct such screening without selecting an asymptomatic population.

This article highlights the characteristics and clinical symptoms of esophageal involvement in patients with SSc.Patients and Methods: This study was conducted between November 2022 to August 2023, including 26 already diagnosed cases of SSc in the Department of Rheumatology and Rehabilitation and Kurdistan Center for Gastroenterology and Hepatology-Sulaymaniyah, Iraq. Esophageal involvement was investigated using esophageal manometry, esophagogastroduodenoscopy (EGD), and 24-hour impedance-pH monitoring.Results: Females were significantly predominant (P = 0.019) regarding the symptoms; 76.9% of the patients had heart burn, 76.9% dysphagia, 73.1% water brush, and 69.2% regurgitation. In total, 69.2% of the patients showed erosive gastrointestinal reflux disease (GERD) on EGD, 76.9% had decreased lower esophageal sphincter pressure (DLESP) and decreased distal esophageal peristaltic contractions (DDEPC) on esophageal manometry, and 84.6% had reflux on pH monitoring. Raynaud’s phenomenon is the most common and typically the earliest clinical manifestation of SSc. The presence of erosive GERD was found to significantly increase the risk of developing dysphagia (B = 4.725, P = 0.014, OR = 3.482) and regurgitation (B = 3.521, P = 0.006, OR = 4.030).Conclusion: It is crucial to take gender-specific considerations into account when diagnosing and managing esophageal complications in patients with systemic sclerosis (SSc). Additionally, employing various diagnostic assessments to detect esophageal involvement during SSc is essential. Erosive GERD has been identified as a risk factor that contributes to the development of dysphagia and regurgitation in individuals with SSc.Keywords: esophageal involvement, esophageal manometry, esophagogastroduodenoscopy, 24-hour Impedance-pH Monitoring, systemic sclerosis

Abstract Background Endoscopic features of intestinal transplant-associated microangiopathy (iTAM) have not been comprehensively investigated. This study aimed to examine the endoscopic characteristics of patients diagnosed with iTAM. Methods This retrospective analysis included 14 patients pathologically diagnosed with iTAM after stem cell transplantation for hematolymphoid neoplasms (n = 13) or thalassemia (n = 1). The sex, age at diagnosis, endoscopic features, and prognosis of each patient were assessed. Serological markers for diagnosing transplant-associated thrombotic microangiopathy were also evaluated. Results The mean age at the time of iTAM diagnosis was 40.2 years. Patients diagnosed based on the pathognomonic pathological changes of iTAM presented with diverse symptoms at the times of endoscopic examinations, including diarrhea (n = 10), abdominal pain (n = 5), nausea (n = 4), appetite loss (n = 2), bloody stools (n = 2), abdominal discomfort (n = 1), and vomiting (n = 1). At the final follow-up, six patients survived, while eight patients succumbed, with a median time of 100.5 days (range: 52–247) post-diagnosis. Endoscopic manifestations included erythematous mucosa (n = 14), erosions (n = 13), ulcers (n = 9), mucosal edema (n = 9), granular mucosa (n = 9), and villous atrophy (n = 4). Erosions and/or ulcers were primarily observed in the colon (10/14, 71%), followed by the ileum (9/13, 69%), stomach (4/10, 40%), cecum (5/14, 36%), duodenum (3/10, 30%), rectum (4/14, 29%), and esophagus (1/10, 10%). Cytomegalovirus infection (n = 4) and graft-versus-host disease (n = 2) coexisted within the gastrointestinal tract. Patients had de novo prolonged or progressive thrombocytopenia (6/14, 43%), decreased hemoglobin concentration (4/14, 29%), reduced serum haptoglobin level (3/14, 21%), and a sudden and persistent increase in lactate dehydrogenase level (2/14, 14%). Peripheral blood samples from 12 patients were evaluated for schistocytes, with none exceeding 4%. Conclusions This study provides a comprehensive exploration of the endoscopic characteristics of iTAM. Notably, all patients exhibited erythematous mucosa throughout the gastrointestinal tract, accompanied by prevalent manifestations, such as erosions (93%), ulcers (64%), mucosal edema (64%), granular mucosa (64%), and villous atrophy (29%). Because of the low positivity for serological markers of transplant-associated thrombotic microangiopathy in patients with iTAM, endoscopic evaluation and biopsy of these lesions are crucial, even in the absence of these serological features.

Background Esophagogastroduodenoscopy (EGD) is vital for the diagnosis and treatment of various gastrointestinal conditions but carries a low risk of venous air embolism (VAE). We report a case of VAE during EGD, confirmed by computed tomographic pulmonary angiography (CTPA). Case A 56-year-old male with a history of hypopharyngeal cancer underwent EGD for dysphagia-related esophageal dilation. Signs of VAE were noted, prompting swift interventions, including oxygen therapy, positional changes, and CTPA. CTPA revealed the Mercedes-Benz sign, pneumomediastinum, and a minimal pneumothorax. The patient’s oxygen saturation improved within 30 min before undergoing CTPA, and he was discharged on postoperative day 4. Conclusions Timely recognition of VAE, resulting in appropriate interventions supported by CTPA, resulted in favorable patient outcomes.

Background: Given the significant burden of upper digestive diseases, there has been a substantial increase in the utilization of esophagogastroduodenoscopy (EGD) in China from 2012 to 2019. The objective of this study is to investigate the development, practice, and factors influencing the widespread use of EGD during this period. Methods: Two national censuses were conducted among all hospitals in mainland China that perform gastrointestinal endoscopy. These censuses aimed to extract information on the infrastructure, volume, and quality of EGD. The analysis of potential factors influencing EGD practice was based on realworld data from open access sources. Results: From 2012 to 2019, the number of hospitals performing EGD in mainland China increased from 1,518 to 2,265 (1.49-fold) in tertiary hospitals and from 3,633 to 4,097 (1.12-fold) in secondary hospitals, respectively. The national utilization rate of EGD also increased from 1,643.53 to 2,018.06 per 100,000 inhabitants, indicating a 1.23-fold increase. Regions with more endoscopists per 100,000 inhabitants (OR 9.61, P<0.001), more tertiary hospitals performing EGD per million inhabitants (OR 2.43, P<0.001), higher incidence of esophageal and gastric cancer (OR 2.09, P=0 016), and higher number of hospitals performing EGD per million inhabitants (OR 1.77, P=0.01) tended to provided more numerous and qualitied EGD. And hospital grading, regional GDP, incidence of esophageal and gastric cancer and the volume of EGD were observed as the significantly relevant factors of malignant dictation rate (MDR) (P<0.05), but not the number and educational background of endoscopists. Conclusion: Over the past seven years, China has made significant progress in EGD. However, challenges persist in terms of quality and inequality. [ABSTRACT FROM AUTHOR]

Aim: The most common complication during esophagogastroduodenoscopy (EGD) under sedation is hypoxemia. There is a scarcity of indicators to predict the risk of hypoxemia during EGD under sedation accurately. The width of the lower tongue base measured by ultrasound (US) is considered to be a significant predictor of the presence and severity of obstructive sleep apnea syndrome (OSAS), which develops hypoxemia by a similar mechanism to EGD under sedation. This study aimed to observe its ability to predict hypoxemia during EGD under sedation. Material and methodsː Adult patients undergoing EGD under sedation at our hospital after assessment in the anesthesia clinic were enrolled in the study. The width of the lower tongue base was measured as the distance between the lingual arteries (DLA) on both sides of the inferior lateral margin of the tongue by US. The primary outcome was hypoxemia defined as the SpO2 <90% for longer than 10 seconds during EGD under sedation. ResultsːA total of 304 patients were successfully included, and hypoxemia was reported in 32 patients (10.5%). The DLA prediction criterion for hypoxemia was >31 mm. The DLA was correlated with hypoxemia (Spearman correlation coefficient, 0.455; p<0.001) and owned the highest area under the receiver operating characteristic curve (0.927; 99% CI, 0.891 to 0.953, compared with that of the other predictors, p< 0.001) with hypoxemia. Conclusionsː The width of the lower tongue base, measured as the DLA by US examination can be used to effectively predict the risk of hypoxemia during EGD under sedation. [ABSTRACT FROM AUTHOR]

Objective: Prevalence of colonoscopy (CS) is an important countermeasure against colorectal cancer (CRC). In this study, we used large-scale data for a comparison of CS with esophagogastroduodenoscopy (EGD) in Japan. Methods: This was a retrospective descriptive study. Commercially anonymized patient data were collected from various health insurance societies (JMDC, Inc. Tokyo, Japan) generated from the insurance registry, receipts (inpatient, outpatient, and prescription), and health checkup data. The data also included healthy subjects who had never been examined in a hospital. The data of 2,760,048 persons who were 50–75 years old during January 2012–December 2019 were extracted from the original data source. The annual rate, the prevalence rate (frequency of those undergoing at least one endoscopy during the period), and the percentage of repeaters (undergoing endoscopy at least twice during the period) of CS were calculated and compared to those of EGD. Results: The annual rates in 2012/2015/2019 were 3.4%/4.5%/5.3% for CS, respectively, and increased gradually from 2012 to 2019. Those rates were 7.0%/7.9%/7.4% for EGD, respectively, and did not increase. The prevalence rates of CS and EGD were 25.3% and 36.2%, respectively, among the 137,246 participants over 8 years. The prevalence rates of individuals in their 50 s/60 s/70 s were 23.0%/25.9%/31.4% for CS and 33.0%/37.6%/40.7% for EGD, respectively. The proportions of males/females were 27.9%/20.7% for CS, and 36.4%/35.8% for EGD, respectively. The repeat rates of CS and EGD were 40.3% and 44.8%, respectively, over 8 years. Conclusions: Using large-scale data, we determined the status of CS and EGD in Japan. [ABSTRACT FROM AUTHOR]

Within the cc-EFTR group, a majority of GISTs were located in the deep muscularis propria or serosal layer, accounting for 96.9%, as opposed to those in the ESD group (45.1%). The R0 resection rates were 51.0% and 84.4% in the ESD and cc-EFTR groups, respectively. Seven (8.4%) patients required surgical treatment (six patients underwent ESD and one underwent cc-EFTR) due to residual tumor (n=5) and post-procedure adverse events (n=2). Patients undergoing R0 or R1 resection did not experience recurrence during a median 14-month follow-up period, except for one patient in the ESD group. Conclusions: cc-EFTR displayed a high R0 resection rate; therefore, it is a safe and effective therapeutic option for small gastric GISTs. [ABSTRACT FROM AUTHOR]

Background/Aims: Nonagenarians will purportedly account for 10% of the United States population by 2050. However, no studies have assessed the outcomes of nonvariceal upper gastrointestinal bleeding (NVUGIB) in this age group. Methods: The National Inpatient Sample database between 2016 and 2020 was used to compare the clinical outcomes of NVUGIB in nonagenarians and octogenarians and evaluate predictors of mortality and the use of esophagogastroduodenoscopy (EGD). Results: Nonagenarians had higher in-hospital mortality than that of octogenarians (4% vs. 3%, p<0.001). EGD utilization (30% vs. 48%, p<0.001) and blood transfusion (27% vs. 40%, p<0.001) was significantly lower in nonagenarians. Multivariate logistic regression analysis revealed that nonagenarians with NVUGIB had higher odds of mortality (odds ratio [OR], 1.5; 95% confidence interval [CI], 1.3-1.7) and lower odds of EGD utilization (OR, 0.86; 95% CI, 0.83-0.89) than those of octogenarians. Conclusions: Nonagenarians admitted with NVUGIB have a higher mortality risk than that of octogenarians. EGD is used significantly in managing NVUGIB among nonagenarians; however, its utilization is comparatively lower than in octogenarians. More studies are needed to assess predictors of poor outcomes and the indications of EGD in this growing population. [ABSTRACT FROM AUTHOR]

This retrospective study, conducted using the U.S. National Inpatient Sample (NIS), examines the outcomes and management of nonvariceal upper gastrointestinal bleeding (NVUGIB) in COVID-19 patients and identifies predictive factors to enhance patient prognosis. We analyzed the 2020 U.S. NIS data involving adult patients (≥18 years) admitted with NVUGIB and categorized them based on the presence of COVID-19. Primary and secondary outcomes, NVUGIB-related procedures, and predictive factors were evaluated. Of 184,885 adult patients admitted with NVUGIB, 1.6% (2990) had COVID-19. Patients with NVUGIB and COVID-19 showed higher inpatient mortality, acute kidney injury, need for intensive care, and resource utilization metrics. Notably, there was a lower rate of early esophagogastroduodenoscopy (EGD). Multivariate logistic regression revealed conditions like peptic ulcer disease, mechanical ventilation, and alcohol abuse as significant positive predictors for NVUGIB in COVID-19 patients, whereas female gender and smoking were negative predictors. Our findings suggest that COVID-19 significantly increases the risk of mortality and complications in NVUGIB patients. The observed decrease in early EGD interventions, potentially contributing to higher mortality rates, calls for a review of treatment strategies. Further multicenter, prospective studies are needed to validate these results and improve patient care strategies. [ABSTRACT FROM AUTHOR]

Crohn's disease (CD) is a progressive, multifactorial, immune-mediated disease characterized by chronic inflammation of any part of the gastrointestinal (GI) tract. Pediatric patients present with a more extensive form of the disease, especially in the upper GI tract with various histopathological inflammatory patterns. Our study aims to analyze the clinical, laboratory, endoscopic, and histopathological findings in children with diagnosed CD and compare results on the initial and follow-up tests. We have included 100 children and adolescents with CD, with performed endoscopic and histopathological (HP) procedures. The results of multiple biopsies executed in these 8 years were matched and compared. We found a statistically significant frequency reduction in stool changes (65.52% to 18.18%), weight loss (35.24% to 4%), and abdominal pain (41.86% to 6.67%) as presenting symptoms. There was an improvement in all laboratory values: fecal calprotectin (1000 to 60,8 μg/g), C-reactive protein (12.2 to 1.9 mg/L), and albumin (36 to 41 g/L). On esophagogastroduodenoscopy and ileo-colonoscopy 36.59% and 64.86% patients had specific findings, respectively. A total of 32 patients had evidence of Crohn's disease in the upper GI tract. Non-caseating granulomas were found on 9% of oesophageal, 18% of gastric, and 12% of duodenal biopsies. In the lower GI tract, we have observed a disease progression in the rectum (72.29 to 82.22%) and descending colon (73.49 to 80%). There was no registered disease progression in the upper GI tract. Our study demonstrated a significant decline in the frequency of symptoms and an improvement in laboratory values on the follow-up examinations. More than a third of our patients had specific endoscopic and HP findings in the upper GI tract, and an additional 23% had HP findings highly suggestive of CD. We demonstrated the importance of regular clinical, laboratory, endoscopic, and histopathological assessments of pediatric CD patients. [ABSTRACT FROM AUTHOR]

Background: Endoscopic features of intestinal transplant-associated microangiopathy (iTAM) have not been comprehensively investigated. This study aimed to examine the endoscopic characteristics of patients diagnosed with iTAM. Methods: This retrospective analysis included 14 patients pathologically diagnosed with iTAM after stem cell transplantation for hematolymphoid neoplasms (n = 13) or thalassemia (n = 1). The sex, age at diagnosis, endoscopic features, and prognosis of each patient were assessed. Serological markers for diagnosing transplant-associated thrombotic microangiopathy were also evaluated. Results: The mean age at the time of iTAM diagnosis was 40.2 years. Patients diagnosed based on the pathognomonic pathological changes of iTAM presented with diverse symptoms at the times of endoscopic examinations, including diarrhea (n = 10), abdominal pain (n = 5), nausea (n = 4), appetite loss (n = 2), bloody stools (n = 2), abdominal discomfort (n = 1), and vomiting (n = 1). At the final follow-up, six patients survived, while eight patients succumbed, with a median time of 100.5 days (range: 52–247) post-diagnosis. Endoscopic manifestations included erythematous mucosa (n = 14), erosions (n = 13), ulcers (n = 9), mucosal edema (n = 9), granular mucosa (n = 9), and villous atrophy (n = 4). Erosions and/or ulcers were primarily observed in the colon (10/14, 71%), followed by the ileum (9/13, 69%), stomach (4/10, 40%), cecum (5/14, 36%), duodenum (3/10, 30%), rectum (4/14, 29%), and esophagus (1/10, 10%). Cytomegalovirus infection (n = 4) and graft-versus-host disease (n = 2) coexisted within the gastrointestinal tract. Patients had de novo prolonged or progressive thrombocytopenia (6/14, 43%), decreased hemoglobin concentration (4/14, 29%), reduced serum haptoglobin level (3/14, 21%), and a sudden and persistent increase in lactate dehydrogenase level (2/14, 14%). Peripheral blood samples from 12 patients were evaluated for schistocytes, with none exceeding 4%. Conclusions: This study provides a comprehensive exploration of the endoscopic characteristics of iTAM. Notably, all patients exhibited erythematous mucosa throughout the gastrointestinal tract, accompanied by prevalent manifestations, such as erosions (93%), ulcers (64%), mucosal edema (64%), granular mucosa (64%), and villous atrophy (29%). Because of the low positivity for serological markers of transplant-associated thrombotic microangiopathy in patients with iTAM, endoscopic evaluation and biopsy of these lesions are crucial, even in the absence of these serological features.

Objective: To determine the frequency and risk factors for inadequate bowel preparation using Boston Bowel Preparation Scale. Study Design: Cross-sectional study. Setting: Gastroenterology Department, Liaquat National Hospital, Karachi, Pakistan. Period: September 2022 to June 2023. Methods: The study comprised of patients between 18 to 70 years undergoing colonoscopy. Boston bowel preparation score (BBPS) was used to evaluate the quality of bowel preparation before washing or suctioning. Total score was calculated taking sum of scores in all three segments. Adequate preparation was defined as all 3 BBPS segment scores = 2. Results: In a total of 136 patients, the mean age was 55.8±14.1 years. The mean BBPS score was 5.7±3.5. Based on the criteria of overall adequate rate, inadequate preparation was seen among 44 (32.4%) patients. Lower risk of inadequate preparation was significantly associated with outpatient patients, patients consuming more water and patients with liquid stool consistency whereas odds were significantly higher among patients with age 50 years and above, males, diabetic patients, patients receiving movcal sachet and dulcolex for preparation, patients with lower number of stools (2-4 stools per day) and, patients receiving insulin. Conclusion: The risk of inadequate preparation was higher among older age patients, male gender, diabetic patients, and patients with less number of stools with semi solid consistency.

Introduction: Upper endoscopy is the standard method for diagnosing early-stage gastric cancer. However, according to estimates, up to 20% of tumors are not detected, and their accuracy may be affected by the variability in their performance. In Colombia, most diagnoses take place in advanced stages, which aggravates the problem. Protocols have been proposed to ensure the complete observation of areas prone to premalignant lesions to address variability. Objective: To build and validate an automatic audit system for endoscopies using artificial intelligence techniques. Methodology: In this study, 96 patients from a teaching hospital underwent video-documented endoscopies, spanning 22 stations rearranged to minimize overlaps and improve the identification of 13 key gastric regions. An advanced convolutional network was used to process the images, extracting visual characteristics, which facilitated the training of artificial intelligence in the classification of these areas. Results: the model, called Gastro UNAL, was trained and validated with images of 67 patients (70% of cases) and tested with 29 different patients (30% of cases), which reached an average sensitivity of 85,5% and a specificity of 98,8% in detecting the 13 gastric regions. Conclusions: The effectiveness of the model suggests its potential to ensure the quality and accuracy of endoscopies. This approach could confirm the regions evaluated, alerting less experienced or trained endoscopists about blind spots in the examinations, thus, increasing the quality of these procedures.

Background: Esophagogastroduodenoscopy (EGD) is vital for the diagnosis and treatment of various gastrointestinal conditions but carries a low risk of venous air embolism (VAE). We report a case of VAE during EGD, confirmed by computed tomographic pulmonary angiography (CTPA). Case: A 56-year-old male with a history of hypopharyngeal cancer underwent EGD for dysphagia-related esophageal dilation. Signs of VAE were noted, prompting swift interventions, including oxygen therapy, positional changes, and CTPA. CTPA revealed the Mercedes-Benz sign, pneumomediastinum, and a minimal pneumothorax. The patient's oxygen saturation improved within 30 min before undergoing CTPA, and he was discharged on postoperative day 4. Conclusions: Timely recognition of VAE, resulting in appropriate interventions supported by CTPA, resulted in favorable patient outcomes. [ABSTRACT FROM AUTHOR]

The intricate architecture of gastric anatomy coupled with the complexities inherent in esophagogastroduodenoscopy (EGD) procedures can lead to blind spots during examinations. These blind spots refer to anatomical locations not visualized during EGD examinations, potentially impacting timely diagnoses and treatments, and exacerbating patient conditions. Therefore, developing artificial intelligence (AI) for monitoring and reducing blind spots in EGD examinations is crucial. This study introduces MMCNet, a novel deep-learning model for classifying anatomical locations in EGD images. The model-based AI system can promptly alert the physician when it fails to recognize all anatomical locations in real-time EGD examinations, thereby enabling the monitoring and reduction of blind spots. To validate its efficacy, comprehensive experimental assessments compared MMCNet with established deep learning models. The results confirm MMCNet’s high accuracy rate of 97.25% in recognizing anatomical locations in EGD images. Moreover, its notably compact memory size of 4.16M contributes to reduced memory requirements. With its accuracy and small model size, the model demonstrates significant potential as an effective tool for computer-assisted blind spot detection. Additionally, this study presents a comprehensive workflow for applying deep learning models to address practical issues, which can be easily adapted for similar tasks. [ABSTRACT FROM AUTHOR]

BackgroundThe optimal timing of esophagogastroduodenoscopy (EGD) and the impact of clinico-demographic factors on hospitalization outcomes in non-variceal upper gastrointestinal bleeding (NVUGIB) remains an area of active research.AimTo identify independent predictors of outcomes in patients with NVUGIB, with a particular focus on EGD timing, anticoagulation (AC) status, and demographic features.MethodsA retrospective analysis of adult patients with NVUGIB from 2009 to 2014 was performed using validated ICD-9 codes from the National Inpatient Sample database. Patients were stratified by EGD timing relative to hospital admission (≤ 24 h, 24-48 h, 48-72 h, and > 72 h) and then by AC status (yes/no). The primary outcome was all-cause inpatient mortality. Secondary outcomes included healthcare usage.ResultsOf the 1082516 patients admitted for NVUGIB, 553186 (51.1%) underwent EGD. The mean time to EGD was 52.8 h. Early (< 24 h from admission) EGD was associated with significantly decreased mortality, less frequent intensive care unit admission, shorter length of hospital stays, lower hospital costs, and an increased likelihood of discharge to home (all with P < 0.001). AC status was not associated with mortality among patients who underwent early EGD (aOR 0.88, P = 0.193). Male sex (OR 1.30) and Hispanic (OR 1.10) or Asian (aOR 1.38) race were also independent predictors of adverse hospitalization outcomes in NVUGIB.ConclusionBased on this large, nationwide study, early EGD in NVUGIB is associated with lower mortality and decreased healthcare usage, irrespective of AC status. These findings may help guide clinical management and would benefit from prospective validation.

BackgroundEsophagogastroduodenoscopy (EGD) is a fundamental procedure for early detection of upper gastrointestinal (UGI) cancer. However, limited research has been conducted on the impact of sedation during EGD on the identification of precancerous lesions and early cancer (EC). This retrospective study aims to evaluate whether sedation during EGD can improve the detection rates of precancerous lesions and EC.MethodsIn this propensity score-matched retrospective study, we examined medical records from outpatients who underwent diagnostic EGD at a large tertiary center between January 2023 and December 2023. Data on endoscopic findings and histology biopsies were obtained from an endoscopy quality-control system. The primary objective was to compare the rates of detecting precancerous lesions and EC in patients who received sedation during EGD vs. those who did not receive sedation. Additionally, we aimed to identify factors influencing these detection rates using binary logistic regression analysis.ResultsFollowing propensity score matching, a total of 17,862 patients who underwent diagnostic EGD with or without propofol sedation were identified. The group that received sedation exhibited a higher detection rate of precancerous lesions and EC in comparison to the non-sedated group (1.04 vs. 0.75%; p = 0.039). Additionally, within the sedated group, there was an increased likelihood of identifying precancerous lesions and EC specifically at the gastric antrum (0.60 vs. 0.32%, p = 0.006). Binary logistic regression analysis demonstrated that independent risk factors influencing the detection rates included age, gender, observation time, and number of biopsies conducted during the procedure.ConclusionAnesthesia assistance during EGD screening proved advantageous in detecting EC as well as precancerous lesions. It is crucial for endoscopists to consider these factors when performing EGD screening procedures.

Background/Aims: The impact of sedation on cardio-cerebrovascular (CCV) adverse events after esophagogastroduodenoscopy (EGD) in patients with gastric cancer (GC) is unclear. We investigated the incidence rate and impact of sedation on CCV adverse events after surveillance EGD in patients with GC. Methods : We performed a nationwide population-based cohort study using the Health Insurance Review and Assessment Service databases from January 1, 2018, to December 31, 2020. Using a propensity score-matched analysis, patients with GC were divided into two groups: sedative agent users and nonusers for surveillance EGD. We compared the occurrence of CCV adverse events within 14 days between the two groups. Results : Of the 103,463 patients with GC, newly diagnosed CCV adverse events occurred in 2.57% of patients within 14 days after surveillance EGD. Sedative agents were used in 41.3% of the patients during EGD. The incidence rates of CCV adverse events with and without sedation were 173.6/10,000 and 315.4/10,000, respectively. Between sedative agent users and nonusers based on propensity score matching (28,008 pairs), there were no significant differences in the occurrence of 14-day CCV, cardiac, cerebral, and other vascular adverse events (2.28% vs 2.22%, p=0.69; 1.44% vs 1.31%, p=0.23; 0.74% vs 0.84%, p=0.20; 0.10% vs 0.07%, p=0.25, respectively). Conclusion : s: Sedation during surveillance EGD was not associated with CCV adverse events in patients with GC. Therefore, the use of sedative agents may be considered in patients with GC during surveillance EGD without excessive concerns about CCV adverse events.

The relevance of the study is driven by the rapid increase in the number of small domestic animals with surgical pathology of the digestive system, requiring effective diagnosis and surgical intervention. In this regard, the purpose of this study is to investigate the prevalence of various diseases of the digestive organs in small domestic animals and to determine the most informative methods of their diagnosis. The primary approach in the study is to compare the informativeness of results obtained from examining sick animals, including general (history collection, examination, palpation) and special (ultrasound diagnostics of abdominal organs, endoscopy of the digestive tract, radiography) diagnostic methods. The advantages and disadvantages of different special diagnostic methods were identified and analysed, providing a comprehensive assessment of indications and contraindications for their application in clinical veterinary practice. Out of 1863 animals that presented to the veterinary clinic, pathologies of the digestive tract of various origins were diagnosed in 957 animals. Conservative care was provided to 79.7% of the affected animals (763 individuals). Complicated pathologies requiring surgical treatment were diagnosed in 194 (20.3%) animals. Among these, 170 (17.7%) had foreign bodies in the stomach, 14 (1.5%) had gastric erosions, 4 (0.4%) had neoplasms, 3 (0.3%) had perforations, and 3 (0.3%) had inflammatory diseases. The use of ultrasound diagnostics allowed for the detection of linear foreign bodies in the stomach and the identification of associated complications such as stomach or intestinal perforations caused by foreign bodies. Radiographic examination proved effective when radiopaque structures (metals, stones, bones) were present as foreign bodies. The materials of the study provide practical value for both researchers and practising veterinarians, offering the opportunity to utilise new instrumental diagnostic methods to assess the feasibility of surgical manipulations on the stomach and intestines in dogs and cats

Abstract The objective of this study was to clarify the long-term prognosis of patients with gastric mucosa-associated lymphoid tissue (MALT) lymphoma with additional copies of MALT1. In this multicenter retrospective study, we enrolled 145 patients with gastric MALT lymphoma who underwent fluorescence in situ hybridization (FISH) analysis to detect t(11;18) translocation. The patient cohort was divided into three groups: Group A (n = 87), comprising individuals devoid of the t(11;18) translocation or extra MALT1 copies; Group B (n = 27), encompassing patients characterized by the presence of the t(11;18) translocation; and Group C (n = 31), including patients with extra MALT1 copies. The clinical outcomes in each cohort were collected. Over the course of a mean follow-up of 8.5 ± 4.2 years, one patient died of progressive MALT lymphoma, while 15 patients died due to etiologies unrelated to lymphoma. The progression or relapse of MALT lymphoma was observed in 11 patients: three in Group A, two in Group B, and six in Group C. In Groups A, B, and C, the 10-year overall survival rates were 82.5%, 93.8%, and 86.4%, respectively, and the 10-year event-free survival rates were 96.1%, 96.0%, and 82.9%, respectively. The event-free survival rate in Group C was significantly lower than that in Group A. However, no differences were observed in the 10-year event-free survival rates among individuals limited to stage I or II1 disease (equivalent to excluding patients with stage IV disease in this study, as there were no patients with stage II2), with rates of 98.6%, 95.8%, and 92.3% for Groups A, B, and C, respectively. In conclusion, the presence of extra copies of MALT1 was identified as an inferior prognostic determinant of event-free survival. Consequently, trisomy/tetrasomy 18 may serve as an indicator of progression and refractoriness to therapeutic intervention in patients with gastric MALT lymphoma, particularly stage IV gastric MALT lymphoma.

Abstract Background Current studies have shown that longer observation time can improve neoplastic detection rate. This study aimed to clarify whether endoscopists with longer observation times can detect more focal lesions. Methods Based on the mean examination time for Esophagogastroduodenoscopy (EGD) without biopsy, endoscopists were divided into fast and slow groups, and the detection rate of focal lesions was compared between the two groups. Univariate analysis, multivariate analysis and restricted cubic spline were used to explore the factors of focal lesion detection rate. Results Mean examination time of EGD without biopsy was 4.5 min. The cut-off times used were 5 min. 17 endoscopists were classified into the fast (4.7 ± 3.6 min), and 16 into the slow (7.11 ± 4.6 min) groups. Compared with fast endoscopists, slow endoscopists had a higher detection rate of focal lesions (47.2% vs. 51.4%, P

Abstract Background Suspected upper gastrointestinal bleeding (SUGIB) is a common issue during ICU stay. In the absence of specific guidelines on the indication and timing of esophagogastroduodenoscopy (EGD), there is substantial variability in EGD indication depending on accessibility and clinical presentation. This study aimed to investigate factors associated with the need for per-EGD hemostatic therapy and to create a score predicting therapeutic benefit of emergency bedside EGD in ICU patients with SUGIB. Methods We conducted a retrospective study in our ICU to identify factors associated with the need for hemostatic procedure during EGD performed for SUGIB. From this observational cohort, we derived a score predicting the need for hemostasis during EGD, the SUGIBI score. This score was subsequently validated in a retrospective multicenter cohort. Results Two hundred fifty-five patients not primarily admitted for GI bleeding who underwent a bedside EGD for SUGIB during their ICU stay were analyzed. The preeminent EGD indication were anemia (79%), melena (19%), shock (14%), and hematemesis (13%). EGD was normal in 24.7% of cases, while primary lesions reported were ulcers (23.1%), esophagitis (18.8%), and gastritis (12.5%). Only 12.9% of patients underwent hemostatic endotherapy during EGD.

Malignant melanoma is a neoplasm of melanin-producing cells predominantly of cutaneous origin, which uncommonly develops within gut mucosa. We present the case of a 58-year-old woman with complaints of abdominal pain, loss of appetite and weight. Esophagogastroduodenoscopy revealed a gastric mass and systemic imaging demonstrated widespread nodal and bilateral adrenal gland involvement. Histopathology of the gastric mass confirmed primary malignant mucosal melanoma of the stomach. The patient received three cycles of Nivolumab but did not respond, and thus, was then offered best supportive care. Although infrequent, mucosal melanoma can arise from the gastrointestinal tract, and in contrast to the cutaneous form, advanced disease usually has a dismal prognosis and responds poorly to immune checkpoint inhibitors. Primary gastric melanoma is an aggressive disease that is diagnosed by exclusion after the differential diagnosis of metastasis from a cutaneous or unknown primary site has been conducted. If available, patients with treatment-naïve mucosal melanoma should be considered for enrollment in clinical trials.

Background: Esophagogastroduodenoscopy (EGD) is an endoscopic examination of the upper gastrointestinal tract that requires insufflation with gas, leading to intra-abdominal hypertension (IAH). There is evidence suggesting that IAH positively correlates with intracranial pressure (ICP) and possibly with intraocular pressure (IOP). The aim of this study was to examine the effect of a routine screening EGD on the IOP. Methods: In this observational study, 25 patients were recruited; 15 males with a mean age of 50 ± 18 years and 10 females with a mean age of 45 ± 14 years. EGD was conducted under sedation in 21 subjects. Both eyes' IOP measurements were performed using Tonopen Avia in the sitting and left lateral decubitus positions before sedation and the start of EGD, and subsequently in the left lateral decubitus position when the endoscope reached the duodenum (D2) and at the end of the procedure. The final measurement was performed in the sitting position 10 min after the end of the procedure. Results: The mean IOP in the sitting position was 15.16 ± 2.27 mmHg, and in the left lateral decubitus position, 15.68 ± 2.82 mmHg. When the gastroscope entered the D2, it was 21.84 ± 6.55 mmHg, at the end of the procedure, 15.80 ± 3.25 mmHg, and 10 min later, 13.12 ± 3.63 mmHg. There was a statistically significant IOP increase when the gastroscope entered the duodenum (p < 0.01). At the end of the gastroscopy, the IOP significantly decreased compared to the one registered when the gastroscope entered the D2 (p < 0.001) and it became similar to the values measured before the EGD, in the same left lateral decubitus position (p > 0.05). Conclusion: Significant changes in IOP were observed during the EGD. IOP fluctuations during EGD should be taken into account, especially in patients that need repeated EGDs during their life or in patients with glaucoma. Further studies are needed to better understand the short-effect and long-effect influence of an IOP increase in these patients. [ABSTRACT FROM AUTHOR]

Introduction: The treatment of peptic ulcer disease (PUD) has undergone significant changes over time. Elective surgical treatment of PUD has been replaced by medical treatment. Surgical treatment of PUD is limited to ulcer complications and disease resistant to medical treatment. The main issue to be decided during surgery is whether to add a definitive anti-ulcer surgery in addition to treating the immediate ulcer complication. Our aim in this study is to share the results of gastric ulcer complications treated with open and laparoscopic methods in our clinic and the postoperative endoscopy results of these patients. Materials and Methods: Patients who underwent open or closed ulcer surgery due to ulcer complications in our General Surgery clinic between 2014 and 2023 were retrospectively scanned from the hospital information system. In addition to demographic data such as patients' age and gender, the surgical method applied, duration of hospital stays, and endoscopy findings in patients who underwent endoscopy during the postoperative period were recorded. The results were examined. Results: A total of 194 patients were included in the study. Of the patients, 178 (91.8%) were male and 16 (8.2%) were female. The patients were between the ages of 18 and 93, with a mean age of 45.4±20.4 years. Endoscopy was performed on 44 patients after surgery. The mean duration between surgery and endoscopy was 504±586 days. Of the surgeries, 145 (74.7%) were open and 49 (25.3%) were laparoscopic. Gastritis and erosion were the most frequently observed findings in postoperative endoscopies, with bleeding in 2 patients, stenosis in 4 patients, and recurrent ulcers in 16 patients. Conclusion: Surgical treatment of PUD can be performed using open and laparoscopic methods. Despite the advances in medical treatments, ulcer complications are still observed after surgery. The dilemma of whether to add anti-ulcer treatment to emergency surgeries continues, and more comprehensive studies are needed in this regard. [ABSTRACT FROM AUTHOR]

Esophagogastroduodenoscopies (EGD) are aerosol-generating procedures that may spread respiratory pathogens. We aim to investigate the production of airborne aerosols and droplets during Cytosponge procedures, which are being evaluated in large-scale research studies and National Health Service (NHS)implementation pilots to reduce endoscopy backlogs. We measured 18 Cytosponge and 37 EGD procedures using a particle counter (diameters = 0.3–25 μm), taking measurements 10 cm from the mouth. Two particle count analyses were performed: whole procedure and event-based. Direct comparison with duration-standardized EGD procedures shows that Cytosponge procedures produce 2.16× reduction (P  < 0.001) for aerosols and no significant change for droplets (P =  0.332). Event-based analysis shows that particle production is driven by throat spray (aerosols: 138.1× reference, droplets: 16.2×), which is optional, and removal of Cytosponge (aerosols: 14.6×, droplets: 62.6×). Cytosponge burping produces less aerosols than EGD (2.82×, P  < 0.05). Cytosponge procedures produce significantly less aerosols and droplets than EGD procedures and thus reduce two potential transmission routes for respiratory viruses. [ABSTRACT FROM AUTHOR]

The quality of upper gastrointestinal endoscopy (EGD) is crucial and carries significant consequences for patient outcomes, the employment of healthcare resources, and the future course of gastroenterology as a medical specialty. In this review, we navigate through the terrain of the Quality Indicators (QIs) for EGD, shedding light on their indispensable function in ensuring and augmenting the quality of patient care throughout the pre-procedural, intra-procedural, post-procedural, and outcome-oriented facets of the practice. We delve into the comprehensive scope of the QIs and the challenges impeding the delivery of high-quality EGD, from variability in practitioner training and patient compliance to the systemic limitations of current QIs and the barriers hindering the adoption of advanced techniques. Future directions for bolstering the quality of EGD are highlighted, encapsulating the integration of emergent endoscopic technologies, the evolution of patient-centered metrics, the refinement of endoscopist training and credentialing processes, and the promise held by Artificial Intelligence (AI). Particular emphasis is placed on the role of advanced endoscopic techniques and equipment in enhancing EGD quality. This article presents a cogent narrative, promoting the pursuit of excellence in EGD as an ever-evolving endeavor that necessitates the collective dedication of clinicians, researchers, educators, and policymakers.

Patients with squamous cell carcinoma (SCC) of the head and neck including the oral cavity have a high risk of upper gastrointestinal cancer, especially esophageal cancer. Synchronous upper gastrointestinal cancers affect the field of radiation or surgery, and undetected double cancer can cause poor prognosis. The purpose of this retrospective study was to evaluate the diagnostic performance of 18 F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) for detecting synchronous upper gastrointestinal cancer at the initial staging of oral cancer patients. Between September 2006 and August 2021, 804 newly diagnosed oral squamous cell carcinoma patients who undergo esophagogastroduodenoscopy (EGD) and FDG-PET/CT at the initial staging were enrolled in this study. The incidence of synchronous upper gastrointestinal cancer in EGD screening at the initial staging of oral cancer was retrospectively calculated. Furthermore, we evaluated the diagnostic performance of FDG-PET/CT for screening of synchronous upper gastrointestinal cancer in oral cancer patients. The incidence of synchronous upper gastrointestinal cancer in EGD screening at the initial staging of oral cancer was 4.2% (34/804 patients). Of 34 oral cancer patients with synchronous upper gastrointestinal cancer, 26 (76.5%) had both smoking and drinking habits. The sensitivity, specificity, accuracy, false-negative rate, false-positive rate, positive predictive value, and negative predictive value of FDG-PET/CT for synchronous upper gastrointestinal cancer were 44.1%, 99.6%, 97.3%, 55.9%, 0.4%, 83.3%, and 97.6%, respectively. Because PET/CT cannot sufficiently detect synchronous upper gastrointestinal cancer in oral SCC patients, EGD screening before the treatment may be suitable for the high-risk oral SCC patients.

Background/Aim: Esophagogastroduodenoscopy (EGD) is an effective screening method for early detection of gastric cancer. The GAGLESS mouthpiece has a structure that widens the pharyngeal cavity and suppresses the pharyngeal reflex. This study aimed to investigate the acceptability, safety, and feasibility of transnasal and peroral ultrathin endoscopy using GAGLESS mouthpieces (Clinical Trial Number: UMIN000036922). Patients and Methods: This study was a multicenter, prospective, randomized, open-label trial performed using a questionnaire. The study included 101 consecutive patients who visited the participating medical institutions between June 2019 and March 2022 (median age=47 years, range=24-87 years; all male). Patients aged =20 years at the time of consent acquisition who were the first to undergo EGD were included in the study. The primary endpoint was the degree of distress during EGD, as determined using a visual analog scale (VAS). Results: The VAS score during endoscopic passage through the pharynx was significantly better in the transnasal endoscopy group than in the oral endoscopy group (2.420 vs. 4.092, p=0.001). There was no significant difference in the VAS scores between the two groups during anesthesia or throughout the examination. Compared with nasal endoscopy, oral endoscopy with a GAGLESS mouthpiece did not reduce the VAS score but did significantly improve gastric visibility. Conclusion: For patients in whom there was difficulty in inserting a nasal endoscope, using a GAGLESS mouthpiece rather than a conventional mouthpiece may be more useful in reducing pain.

The clinical outcomes in each cohort were collected. Over the course of a mean follow-up of 8.5 ± 4.2 years, one patient died of progressive MALT lymphoma, while 15 patients died due to etiologies unrelated to lymphoma. The progression or relapse of MALT lymphoma was observed in 11 patients: three in Group A, two in Group B, and six in Group C. In Groups A, B, and C, the 10-year overall survival rates were 82.5%, 93.8%, and 86.4%, respectively, and the 10-year event-free survival rates were 96.1%, 96.0%, and 82.9%, respectively. The event-free survival rate in Group C was significantly lower than that in Group A. However, no differences were observed in the 10-year event-free survival rates among individuals limited to stage I or II1 disease (equivalent to excluding patients with stage IV disease in this study, as there were no patients with stage II2), with rates of 98.6%, 95.8%, and 92.3% for Groups A, B, and C, respectively. In conclusion, the presence of extra copies of MALT1 was identified as an inferior prognostic determinant of event-free survival. Consequently, trisomy/tetrasomy 18 may serve as an indicator of progression and refractoriness to therapeutic intervention in patients with gastric MALT lymphoma, particularly stage IV gastric MALT lymphoma.

Compared with fast endoscopists, slow endoscopists had a higher detection rate of focal lesions (47.2% vs. 51.4%, P < 0.001), especially in the detection of gastric lesions (29.7% vs. 35.9%, P < 0.001). In univariate and multivariate analyses, observation time, patient age and gender, expert, biopsy rate, and number of images were factors in FDR. There is a nonlinear relationship between observation time and FDR. Conclusion: Longer examination time improves the detection rate of focal lesions. Observation time is an important quality indicator of the EGD examination. [ABSTRACT FROM AUTHOR]

EGD was normal in 24.7% of cases, while primary lesions reported were ulcers (23.1%), esophagitis (18.8%), and gastritis (12.5%). Only 12.9% of patients underwent hemostatic endotherapy during EGD. A SUGIBI score < 4 had a negative predictive value of 95% (91–99) for hemostatic endotherapy [AUC of 0.81; 0.75–0.91 (p < 0.0001)]. The SUGIBI score for predicting the need for an EGD-guided hemostatic procedure was next validated in a multicenter cohort with an AUC of 0.75 (0.66–0.85) (p < 0.0001), a score < 4 having a negative predictive value of 95% (92–97). Conclusions: Our study shows that the therapeutic usefulness of bedside emergency EGD for SUGIB in critically ill patients is limited to a minority of patients. The SUGIBI score should help clinicians stratify the probability of a therapeutic EGD. [ABSTRACT FROM AUTHOR]

Esophagogastroduodenoscopy (EGD) is a diagnostic and therapeutic study for various upper gastrointestinal tract diseases. It is a fundamental part of the education and training fellows receive in gastroenterology programs, focusing on developing skills to perform it safely, effectively, and efficiently and master the technique. Historically, value has been attached to the number of procedures required to acquire skills; there is a discrepancy in the recommendations by scientific societies regarding the "ideal" number to meet the minimum requirements and learn the necessary skills. However, each student has different innate and developed abilities that make this process asymmetric. Adopting a combined training approach (observation, clinical practice, and simulation) is the best method to learn diagnostic EGD. We are facing a generation with forms of learning different from those traditionally implemented, which implies an ongoing process of training and updating for endoscopists dedicated to teaching.

Esophagogastroduodenoscopy (EGD) screening is being implemented in countries with a high incidence of upper gastrointestinal (UGI) cancer. High‐quality EGD screening ensures the yield of early diagnosis and prevents suffering from advanced UGI cancer and minimal operational‐related discomfort. However, performance varied dramatically among endoscopists, and quality control for EGD screening remains suboptimal. Guidelines have recommended potential measures for endoscopy quality improvement and research has been conducted for evidence. Moreover, artificial intelligence offers a promising solution for computer‐aided diagnosis and quality control during EGD examinations. In this review, we summarized the key points for quality assurance in EGD screening based on current guidelines and evidence. We also outline the latest evidence, limitations, and future prospects of the emerging role of artificial intelligence in EGD quality control, aiming to provide a foundation for improving the quality of EGD screening.

The relevance of the study is driven by the rapid increase in the number of small domestic animals with surgical pathology of the digestive system, requiring effective diagnosis and surgical intervention. In this regard, the purpose of this study is to investigate the prevalence of various diseases of the digestive organs in small domestic animals and to determine the most informative methods of their diagnosis. The primary approach in the study is to compare the informativeness of results obtained from examining sick animals, including general (history collection, examination, palpation) and special (ultrasound diagnostics of abdominal organs, endoscopy of the digestive tract, radiography) diagnostic methods. The advantages and disadvantages of different special diagnostic methods were identified and analysed, providing a comprehensive assessment of indications and contraindications for their application in clinical veterinary practice. Out of 1863 animals that presented to the veterinary clinic, pathologies of the digestive tract of various origins were diagnosed in 957 animals. Conservative care was provided to 79.7% of the affected animals (763 individuals). Complicated pathologies requiring surgical treatment were diagnosed in 194 (20.3%) animals. Among these, 170 (17.7%) had foreign bodies in the stomach, 14 (1.5%) had gastric erosions, 4 (0.4%) had neoplasms, 3 (0.3%) had perforations, and 3 (0.3%) had inflammatory diseases. The use of ultrasound diagnostics allowed for the detection of linear foreign bodies in the stomach and the identification of associated complications such as stomach or intestinal perforations caused by foreign bodies. Radiographic examination proved effective when radiopaque structures (metals, stones, bones) were present as foreign bodies. The materials of the study provide practical value for both researchers and practising veterinarians, offering the opportunity to utilise new instrumental diagnostic methods to assess the feasibility of surgical manipulations on the stomach and intestines in dogs and cats [ABSTRACT FROM AUTHOR]

Background and aimEsophagogastroduodenoscopy (EGD) is often performed prior to transesophageal echocardiogram (TEE) to evaluate for esophageal pathologies. Although TEE is a safe procedure, some contraindications exist, such as esophageal varices. The incidence of bleeding with TEE is
