Background and aim: Remimazolam has proved to be a very promising sedative drug in randomized clinical trials for usage in a wide spectrum of patients, including critically ill ones. The purpose of our study was to verify efficacy and safety of remimazolam for procedural sedation during diagnostic and first level operative endoscopy in a real-world setting. Methods: This single centre prospective study evaluated sedation regimen with remimazolam for EGDS and fentanyl and remimazolam for colonoscopy in consecutive ASA 1–3 patients. Results: Seventy-one patients underwent 73 procedures (25 EGDS, 48 colonoscopies) with a total amount of 13.2 ± 8.7 mg and 10.2 ± 6.2 mg of remimazolam administered respectively. In 6 EGDS, rescue sedation with propofol was needed. Transient hypotension was frequent (37%) and no cases of hypoxia occurred. One case of suspected allergy (erythema of the trunk) without anaphylaxis was reported. Conclusions: Procedural sedation can be applied with remimazolam without the use of propofol, obtaining effective sedation in colonoscopies while in EGDS remimazolam alone guarantees the result in a percentage of around 70–75% of cases.

An important impediment to the incorporation of artificial intelligence-based tools into healthcare is their association with so-called black box medicine, a concept arising due to their complexity and the difficulties in understanding how they reach a decision. This situation may compromise the clinician's trust in these tools, should any errors occur, and the inability to explain how decisions are reached may affect their relationship with patients. Explainable AI (XAI) aims to overcome this limitation by facilitating a better understanding of how AI models reach their conclusions for users, thereby enhancing trust in the decisions reached. This review first defined the concepts underlying XAI, establishing the tools available and how they can benefit digestive healthcare. Examples of the application of XAI in digestive healthcare were provided, and potential future uses were proposed. In addition, aspects of the regulatory frameworks that must be established and the ethical concerns that must be borne in mind during the development of these tools were discussed. Finally, we considered the challenges that this technology faces to ensure that optimal benefits are reaped, highlighting the need for more research into the use of XAI in this field.

Background: As a popularly used analgesic adjuvant, intravenous (IV) lidocaine could reduce the consumption of propofol in painless gastrointestinal (GI) endoscopy. However, whether IV lidocaine could affect the incidence of oxygen-desaturation episodes (ODE) during painless GI endoscopy is still unknown. Therefore, we tested the hypothesis that IV lidocaine could decrease the incidence of propofol-induced ODE and involuntary movements in patients during GI endoscopy. Methods: Three hundred twenty-two patients scheduled for GI endoscopy were randomly divided into lidocaine group and control group. After midazolam and sufentanil injection, a bolus of 1.5 mg/kg lidocaine was given and followed by continuous infusion of 4 mg/kg/h in lidocaine group, whereas the same volumes of saline solution in control group. Then, propofol was titrated to produce unconsciousness. The primary outcome was the incidence of ODE during the procedure. The secondary outcomes were the incidence of different degree of hypoxia and corresponding treatments and the involuntary body movements. Results: A total of 300 patients were finally included in the analysis, 147 patients in lidocaine group and 153 in control group. The incidence of ODE was 22% in lidocaine group and 39% in control group (OR:0.052; 95%CI: 0.284–0.889; P = 0.018). IV lidocaine also improved the occurrence of different degree of hypoxia (P = 0.017) and needed few treatments (P = 0.028). The incidence of involuntary body movements (14% vs 26%, P = 0.013) and adverse circulatory events was decreased by IV lidocaine. Conclusions: IV lidocaine adjuvant to propofol-based sedation could reduce the incidence of oxygen-desaturation episodes and involuntary body movements, with fewer adverse circulatory events.

Background/Aims: Although gastrointestinal endoscopy (GIE) is a major contributor to the carbon footprint of national healthcare, the amount of medical waste generated by GIE procedures is not reported in South Korea. This study aimed to measure the amount of medical waste generated from GIE procedures in South Korea. Methods: We conducted a 5-day audit of medical waste generated during GIEs at seven hospitals. During the study period, medical waste in the endoscopy examination rooms was measured twice daily and documented as mass (kg). To calculate the mean mass of disposable waste generated during one esophagogastroduodenoscopy (EGD) and one colonoscopy, the mean mass of medical waste generated from seven examinations was calculated. The mean mass of medical waste generated during GIEs was calculated by dividing the total mass of medical waste generated by the number of GIE procedures. Results: Overall, 3,922 endoscopies were performed and 4,558 kg of waste was generated. The mean weight of medical waste generated per endoscopy was 1.34 kg. Each EGD and colonoscopy generated a mean of 0.24 kg and 0.43 kg of disposable waste, respectively. Applying the mean waste estimates from this study to annual GIE procedures performed in South Korea in 2022 showed that the total medical waste produced from GIE was 13,704,453 kg. In addition, the total masses of medical waste produced during EGD and colonoscopy procedures were 819,766 kg and 2,889,478 kg, respectively. Conclusions: Our quantitative measurement showed that a large amount of medical waste is generated from GIE procedures. However, further research is warranted to reduce medical waste generated during GIE, which is an urgent unmet need. [ABSTRACT FROM AUTHOR]

This study aimed to assess the incidence of post‐discharge nausea and vomiting (PDNV) following sedation with nalbuphine and etomidate and to evaluate the prophylactic effects of scopolamine in reducing PDNV. A two‐stage prospective clinical trial was conducted. The first part involved an observational study of 77 subjects to assess the PDNV incidence post‐sedation with nalbuphine, etomidate, and propofol. The second part compared the effectiveness of palonosetron 0.075 mg (P group), scopolamine 0.1 mg (S group), and their combination (PS group) in reducing PDNV. The primary endpoint was the incidence of PDNV within 8 h post‐sedation. Secondary outcomes included PDNV frequency and severity at 8–24, 0–24, and 24–48 h and side effects of medications. The incidence of PDNV within 8 h post‐sedation was 37.66% (29/77). The PS group showed a significantly lower PDNV rate of 2.56% within 8 h, compared to the P group (35.71%, P <.001), S group (19.64%, P <.001), and control group (38.39%, P <.001), respectively. The S group (19.64%) also had a lower rate than the P group (35.71%, P =.007) and the control group (38.39%, P =.002). Subgroup analysis suggested a potential differential effect of palonosetron in reducing vomiting among male patients undergoing gastrointestinal procedures. The combination therapy was also associated with fewer cases of mild or no nausea and vomiting. In summary, the incidence of PDNV following sedation with nalbuphine and etomidate was notably high. The combination of scopolamine and palonosetron was more effective in preventing PDNV, with implications for improved post‐sedation care. [ABSTRACT FROM AUTHOR]

Esophageal squamous cell carcinoma (ESCC) remains a significant global health challenge, being the sixth leading cause of cancer mortality with pronounced geographic variability. The incidence rates range from 125 per 100,000 in northern China to 1–1.5 per 100,000 in the United States, driven by environmental and lifestyle factors such as tobacco and alcohol use, dietary habits, and pollution. Major modifiable risk factors include tobacco and alcohol consumption, with a synergistic risk increase when combined. Nonmodifiable risk factors include previous diagnoses of head and neck squamous cell carcinoma (H&N SCC), achalasia, and prior radiotherapy. Prevention strategies must be tailored to specific regional burdens to efficiently allocate medical and financial resources. Gastrointestinal endoscopy is crucial in reducing ESCC burden through early detection and characterization of neoplastic changes, such as high‐grade dysplasia. Early diagnosis significantly improves survival rates, while endoscopic resection of noninvasive dysplasia can prevent ESCC onset, reducing treatment burden for advanced disease. Postresection surveillance can detect high‐risk metachronous lesions. Despite these benefits, endoscopic prevention faces challenges, including the lack of high‐level evidence supporting its efficacy, opportunity costs, the need for specialized training and techniques, and the requirement for advanced technology investments. This Position Statement from the World Endoscopy Organization (WEO) aims to address these challenges, supplying recommendations for the exploitation of endoscopic resources regarding the possible role of screening, quality, and training for the detection, characterization, resection, and surveillance of ESCC.

The utilization of artificial intelligence (AI) in gastrointestinal (GI) endoscopy has witnessed significant progress and promising results in recent years worldwide. From 2019 to 2023, the European Society of Gastrointestinal Endoscopy has released multiple guidelines/consensus with recommendations on integrating AI for detecting and classifying lesions in practical endoscopy. In Vietnam, since 2019, several preliminary studies have been conducted to develop AI algorithms for GI endoscopy, focusing on lesion detection. These studies have yielded high accuracy results ranging from 86% to 92%. For upper GI endoscopy, ongoing research directions comprise image quality assessment, detection of anatomical landmarks, simulating image-enhanced endoscopy, and semi-automated tools supporting the delineation of GI lesions on endoscopic images. For lower GI endoscopy, most studies focus on developing AI algorithms for colorectal polyps' detection and classification based on the risk of malignancy. In conclusion, the application of AI in this field represents a promising research direction, presenting challenges and opportunities for real-world implementation within the Vietnamese healthcare context.

Objective: Binaural beats, or the perceptual auditory illusions created when simultaneously presenting two similar frequencies to each ear separately, have been used to reduce anxiety in various procedures. Unfortunately, no prior study involved preprocedure binaural music exposure among patients undergoing upper gastrointestinal endoscopy, and this study sought to investigate its effect on anxiety and tolerance among participants undergoing sedation-free upper gastrointestinal endoscopy. Methods: The prospective, controlled, randomized trial included the participation of 96 Turkish patients aged between 18 and 70 years who were scheduled for an upper gastrointestinal endoscopy, regardless of sex or illness, and were divided randomly into two different groups to undergo endoscopy, namely, the binaural beats group (n = 48) and a control group (n = 48). Patients in the binaural beat music group wore headphones, and music was given 15 mins before endoscopy; however, no particular treatment was given for either group. Anxiety levels were assessed by using the State Trait Anxiety Inventory questionnaire, in addition to changes before and after endoscopy to measure patient satisfaction based on the physician's recorded numbers of retches noted by doctors as tolerance was documented and compared among both groups. Results: The results showed that following this procedure, in the music group, state scores remained significantly lower than before them (p = 0.016), compared with the control group (p > 0.05). There was no significant difference regarding changes in diastolic or systolic heart rate or blood pressure (p > 0.05). However, the procedure tolerance and satisfaction scores were significantly higher in the music group than those without music (p < 0.05). Conclusion: For patients undergoing upper gastrointestinal endoscopy, music with binaural beats was found to significantly reduce anxiety levels and increase patient tolerance, providing an alternative option to sedative medications as a potential sedative treatment option.Clinical trials registration number: NCT06114524.

Background and Aim: Endoscopic submucosal dissection (ESD) is considered the best modality for achieving en bloc resection of larger neoplastic mucosal lesions in the upper and lower gastrointestinal (GI) tract. Multiple devices are available for ESD, and refinements continue to be made to develop devices that improve the safety and efficiency of performing ESD. Submucosal injection with viscous fluids like glycerol, which prolong submucosal expansion, could facilitate the procedure. We aimed to evaluate the safety and performance of the new Erbe HYBRIDknife® flex, which combines electrosurgical dissection with waterjet‐assisted injection in a slim and flexible form factor. Methods: In a prospective animal study with six pigs, four endoscopists, each with 10–20 years of experience in ESD, performed 28 esophageal ESDs. One half was performed with physiological saline injectate, the other half with fructose‐added glycerol. Various performance aspects were evaluated on a five‐point scale [5 = best], including dissection properties, handling, and usability. Results: No perforations or major bleeding occurred. All resections were performed en bloc, with one technical failure (3.6%, 1 of 28). Performance scores were similar for saline and glycerol (4.5 ± 0.31 vs. 4.5 ± 0.32, P = 0.36), as was dissection speed (13 ± 6.2 mm2/min vs. 15 ± 6.1 mm2/min, P = 0.22). Conclusions: We demonstrated that esophageal ESD can be performed safely and rapidly using HYBRIDknife flex, with excellent performance evaluation by the endoscopists. Combining this device with glycerol or saline is precise and effective for ESD, although experience could compensate for the theoretical disadvantage of using normal saline. [ABSTRACT FROM AUTHOR]

Background: Remimazolam tosilate is a new type of benzodiazepine currently used for gastrointestinal endoscopy and can be combined with alfentanil. Aim: This trial compared the effectiveness and safety of remimazolam with alfentanil to propofol with alfentanil in patients undergoing gastrointestinal endoscopy. Method: One hundred and sixty-six patients were randomly divided into propofol-alfentanil anaesthesia (Group P) and remimazolam-alfentanil anaesthesia (Group R). The primary outcomes were perioperative haemodynamic variables, including systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), heart rate (HR) and oxygen saturation (SpO2) preoperatively (T0); after anaesthesia induction (T1); when the gastroscope passed through the oropharynx (T2); 3 min (T3), 5 min (T4) and 7 min (T5) after T2; at the end of surgery (T6); and when patients successfully awakened (T7). The secondary outcomes included induction and awakening time, patient satisfaction, operator satisfaction, and adverse event occurrences. Results: Compared with those in Group P, the SBP in Group R was significantly higher at T1, T2, T3, and T6 (P < 0.05); the DBP and MAP were significantly higher at T1, T2, T3, T5, and T6 (P < 0.05); the HR was significantly faster at T1 to T6 (P < 0.05); the SpO2 was significantly higher at T1 to T4 (P < 0.05); the incidences of hypoxemia, hypotension, and drug injection pain were significantly lower in Group R (P < 0.05); the incidence of hiccups was higher (P < 0.05); the awakening time was shorter in Group R (P < 0.05); and the operator satisfaction score was high (P < 0.05). Conclusion: Compared to propofol with alfentanil, remimazolam with alfentanil can be used safely and effectively for sedation in patients undergoing gastrointestinal endoscopy, with less impact on the patient's circulatory and respiratory systems and a lower incidence of adverse events. Trial registration: This trial protocol was registered in the Chinese Clinical Trial Registry (ChiCR2300077252, date: 2023-11-02). [ABSTRACT FROM AUTHOR]

In response to the annual occurrence of over 10 million gastrointestinal endoscopic examinations in China, this study proposes a personalized anesthesia management model based on multimodal deep learning. This model was designed to enhance anesthesia management efficiency and disease detection rates. In collaboration with the Department of Anesthesiology at Renji Hospital, which is affiliated with the Shanghai Jiao Tong University School of Medicine, data pertaining to anesthesia were collected from 398 patients, who were undergoing gastrointestinal endoscopy. This yielded a total of 327 valid samples. Analysis of the patients’ basic information and physiological parameters during surgery revealed that body mass index (BMI) and age significantly impacted anesthesia management. Based on these findings, a multimodal deep learning model was developed that integrates Long Short-Term Memory (LSTM) networks, hyperparameter geometric manifold optimization (GMO) methods and data-driven sparse matrix classifiers. The model is capable of dynamically adjusting its parameters based on the specific needs of each individual patient, utilizing real-time physiological data to predict vital signs and anesthesia states with a 10-second lead time. In the experimental evaluations, the model demonstrated superior performance in drug usage prediction tasks. Compared with LSTM networks integrated with convolutional neural networks (CNN) and support vector machines (SVM), the LSTM model combined with GMO and sparse matrix classifiers, along with personalized physiological data, achieved a recall rate of 83% and an F1-score of 0.711 in drug usage prediction. The total computation time was maintained within 2.99 seconds, thereby satisfying the requisite for real-time applications. This model significantly improves prediction accuracy and stability over traditional methods, thereby enhancing operational efficiency in complex surgical environments. It is anticipated that the outcomes of this study will promote widespread adoption of gastrointestinal endoscopy, thereby improving the early diagnosis and treatment rates of gastrointestinal diseases.

With the alarmingly increasing prevalence of obesity in the Western world, it has become necessary to provide more acceptable treatment options for patients with obesity. Minimally invasive endoscopic techniques are continuously evolving. Currently, metabolic and bariatric endoscopies encompass several different techniques that can offer significant weight loss and improvement in comorbidities with a favorable safety profile. Restrictive bariatric procedures include the use of intragastric balloons and gastric remodeling techniques with different suturing devices. Several studies have demonstrated the efficacy and safety of these techniques that are widely used in clinical practice. Small intestine-targeted metabolic endoscopy is an intriguing and rapidly evolving field of research, although it is not widespread in routine practice. These techniques include duodenal-jejunal bypass liners, duodenal mucosal resurfacing, and incisionless anastomoses. The aim of this review article is to provide a detailed update on the currently available bariatric endoscopy techniques in Western countries.

The primary outcome was the post-anesthesia care unit (PACU) stay time, defined as the time from the end of the examination to scoring 9 points using the Modified Post-Anesthetic Discharge Scoring System (MPADSS) criteria. Secondary outcomes included sedation-related adverse events, recall, injection pain, as well as postoperative Quality of Recovery-15 (QoR-15) scores and Pittsburgh Sleep Quality Index (PSQI) scores at 1 day, 1 week, and 1 month postoperatively.Results: A total of 351 patients completed the study, with 174 receiving remimazolam and 177 receiving propofol. The PACU stay time in RF group was non-inferior to that in PF group [14 (11, 18) vs 13 (10, 17), mean difference 1 (95% confidence interval 0, 2), P=0.084 for noninferiority]. However, remimazolam was associated with lower rate of hypoxemia [4.7% (8/180) vs 12.4% (22/180), P=0.011], reduced use of vasoactive drugs [1 (0, 1) vs 1 (1, 2), P< 0.001], less injection pain [2 (1.2%) vs 35 (21.3%), P< 0.001], and lower recall [20 (11.8%) vs 36 (20.3%), P=0.034]. There were no differences in the QoR-15 scores and PSQI scores at postoperative 1 day, 1 week, and 1 month between groups.Conclusion: This non-inferiority study revealed that in elderly outpatients undergoing gastrointestinal endoscopy, remimazolam achieved recovery times comparable to propofol, with fewer associated complications.Keywords: remimazolam, postoperative recovery, older patients, gastrointestinal endoscopy

Malignant gastric outlet obstruction (GOO) is a condition characterized by blockage or narrowing where the stomach empties its contents into the small intestine due to primary malignant tumors or metastatic diseases. This condition leads to various symptoms such as nausea, vomiting, abdominal pain, and weight loss. To manage malignant GOO, different treatment options have been employed, including surgical gastrojejunostomy (SGJ), gastroduodenal stenting (GDS) using self-expandable metallic stent (SEMS), and endoscopic ultrasound-guided gastrojejunostomy (EUS-GJ). This review focuses on comparing the clinical outcomes of endoscopic stenting (GDS and EUS-GJ) with SGJ for malignant GOO. Studies have shown that GDS with SEMS provides comparable clinical outcomes and safety for the palliation of obstructive symptoms. The choice between covered and uncovered SEMS remains controversial, as different studies have reported varying results. EUS-GJ, performed via endoscopic ultrasound guidance, has shown promising efficacy and safety in managing malignant GOO, but further studies are needed to establish it as the primary treatment option. Comparative analyses suggest that GDS has higher recurrence and reintervention rates compared to EUS-GJ and SGJ, with similar overall procedural complications. However, bleeding rates were lower with GDS than with SGJ. Randomized controlled trials are required to determine the optimal treatment approach for malignant GOO.

Gastric cancer (GC), a significant cause of mortality globally, is the leading cause of cancer-related deaths among Latin American men. GC is usually diagnosed at an advanced stage; therefore, therapeutic options are limited, and prognosis is poor. Helicobacter pylori infection remains the primary risk factor for GC; therefore, primary prevention directed toward diagnosis and treatment (“test-and-treat” strategy) is important. Western medicine guidelines recommend esophagogastroduodenoscopy (EGD) for at-risk individuals aged >40 years with regular surveillance in patients with gastric premalignant conditions (GPMC). However, limited availability of EGD in Latin America necessitates development of risk stratification tools to minimize the endoscopic burden. Results from the Chilean “Endoscopic Cohort and Histological Operative Link on Gastric Assessment (OLGA) Staging” (ECHOS study), propose endoscopic surveillance of advanced GPMC (OLGA/Operative Link for Gastric Intestinal Metaplasia [OLGIM] stages III–IV) with reliable risk stratification to facilitate early GC detection. Ensuring high-quality EGD and enhanced diagnostic yield of GPMC is essential. GPMC grading tools, such as the Kimura-Takemoto or Endoscopic Grading of Gastric Intestinal Metaplasia classification, should be incorporated into the regular risk assessment protocol. However, obtaining mapping gastric biopsies using standardized methods such as the updated Sydney System biopsy protocol, followed by grading of chronic atrophic gastritis with or without intestinal metaplasia using the OLGA and OLGIM staging systems are preferred for GC risk stratification. Recent GC prevention strategies recommended in Chile include a “test-and-treat” approach for H. pylori in individuals aged 35–44 years and combined H. pylori/pepsinogen I–II serology and EGD evaluation in patients aged >45 years to optimize the limited preventive resources available in the region.

Bezoars, including phytobezoars, trichobezoars, and pharmacobezoars, are accumulations of undigested substances in the gastrointestinal tract. We report three cases of gastric bezoars. Case 1: An 86-year-old woman presented with a one-month history of abdominal pain and vomiting. Esophagogastroduodenoscopy revealed gastric bezoars; consumption of 2 L of cola daily for 2 weeks resulted in complete disappearance of the bezoars. Case 2: An asymptomatic 63-year-old woman underwent esophagogastroduodenoscopy, which revealed a gastric bezoar. Cola spraying and endoscopic lithotomy were ineffective; therefore, the patient underwent laparoscopic removal of the bezoar for management of small bowel obstruction secondary to the bezoar fragments. Case 3: A 6-year-old girl with a history of pica underwent two laparoscopic surgeries 10 months apart for recurrent trichobezoars. We report our treatment approach in three patients who presented with gastric bezoars.

Background: Gastroesophageal Reflux Disease (GERD) is caused by the reflux of gastric contents into the esophagus and has a 13% global prevalence that is increasing. GERD symptoms negatively impact physical, social, and emotional quality of life. The Frequency Scale for the Symptoms of GERD (FSSG) and the Gastrointestinal Symptom Rating Scale (GSRS) determine the efficacy of treatment but may not correlate with endoscopically estimated esophageal mucosal injury severity. We aimed to probe the correlation between FSSG, GSRS, and esophageal injury severity to evaluate whether these scores can predict GERD severity. Methods: A total of 2962 patients who underwent physical examinations, including upper gastrointestinal endoscopy, at the Kyoto Kuramaguchi Medical Center, Japan, were enrolled in this study. Upper gastrointestinal endoscopy was used to diagnose fundic mucosal atrophy, reflux esophagitis based on the Los Angeles (LA) classification, gastroesophageal flap value function (GEFV) based on Hill's classification, and Barrett's esophagus. Endoscopic diagnoses were examined for correlations with FSSG and GSRS scores. Results: In reflux esophagitis, FSSG and GSRS scores correlated with LA-B and LA-C endoscopic diagnosis but not with LA-M and LA-A endoscopic findings. Multiple regression analysis results were similar. FSSG scores reflected advanced fundic gland mucosal atrophy, while GSRS scores associated with high grade of GEFV. Conclusions: This is the first report to examine the correlation between FSSG and GSRS scores and endoscopic findings in a relatively large patient population. Our findings suggest that these scores can diagnose the severity of reflux esophagitis. [ABSTRACT FROM AUTHOR]

Background and Aim: Few studies have evaluated the adenoma detection rate (ADR) of colonoscopy with texture and color enhancement imaging (TXI), a novel image‐enhancing technology. This study compares the detection of colorectal polyps using TXI to that using white light imaging (WLI). Methods: This single‐center retrospective study used propensity‐matched scoring based on the patients' baseline characteristics (age, sex, indication, bowel preparation, endoscopist, colonoscope type, and withdrawal time) to compare the results of patients who underwent chromoendoscopy using WLI or TXI at the Toyoshima Endoscopy Clinic. The differences in polyp detection rates and the mean number of detected polyps per colonoscopy were determined between the TXI and WLI groups. Results: After propensity score matching, 1970 patients were enrolled into each imaging modality group. The mean patient age was 57.2 ± 12.5 years, and 44.5% of the cohort were men. The ADR was higher in the TXI group than in the WLI group (55.0% vs 49.4%, odds ratio: 1.25). High‐risk ADR were more common in the TXI group than in the WLI group (17.6% vs 12.8%; OR: 1.45). The mean number of adenomas per colonoscopy (APC) was higher in the TXI group than in the WLI group (1.187 vs 0.943, OR: 1.12). APC with a flat morphology (1.093 vs 0.848, OR: 1.14) and APC of <6 mm (0.992 vs 0.757, OR: 1.16) were higher in the TXI group than in the WLI group. Conclusion: Compared to WLI, TXI improved the ADR in patients who underwent chromoendoscopy based on actual clinical data. [ABSTRACT FROM AUTHOR]

Objective: To identify risk factors for complications in patients undergoing gastrointestinal endoscopy under acupuncture anesthesia and to construct a nomogram predictive model. Methods: This retrospective study included 292 patients who underwent gastrointestinal endoscopy under acupuncture anesthesia at the Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from June 2020 to May 2023. Logistic regression analysis was used to identify risk factors for complications in patients undergoing gastrointestinal endoscopy under acupuncture anesthesia. A nomogram prediction model was constructed using the RMS package of R4.1.2 software based on the independent risk factors identified. The predictive performance of the model was assessed using consistency index (C-index), calibration curve, and receiver operating characteristic (ROC) curve. Results: Seventy-five patients (25.68%) had complications. Body mass index (BMI), history of cardiovascular diseases, fasting time, history of respiratory diseases, and Sedation-Agitation Scale (SAS) score were identified as risk factors for complications. Based on this risk, a nomogram predictive model was constructed. The C-index of the nomogram model was 0.927. Calibration curve showed a good consistency between actual observations and nomogram predictions. The ROC curve area under curve (AUC) was 0.927 (95% CI: 0.895-0.959), indicating a certain predictive value for the occurrence of complications. When the optimal cut-off value was selected, the sensitivity and specificity of the model were 77.0% and 92.0%, respectively, indicating that the predictive model was effective. Conclusions: BMI, history of cardiovascular disease, fasting time, history of respiratory disease, and SAS score are independent risk factors for complications in patients undergoing gastrointestinal endoscopy under acupuncture anesthesia. The constructed nomogram predictive model has a good performance in predicting the occurrence of complications in patients undergoing gastrointestinal endoscopy with under acupuncture anesthesia.

The integration of robotics into gastrointestinal (GI) endoscopy represents a transformative advancement and bears the potential to bridge the gap between traditional limitations by offering unprecedented precision and control in diagnostic and therapeutic procedures. This review explores the historical progression, current applications and future potential of robotic platforms in GI endoscopy. Originally designed for surgical applications, robotic systems have expanded their reach into endoscopy, potentially enhancing procedural accuracy and reducing ergonomic strain on practitioners. Natural Orifice Transluminal Endoscopic Surgery (NOTES) emerged as a promising technique, leveraging natural orifices to perform minimally invasive surgeries. Despite its initial potential, several factors, including limitations of the available instrumentations and lack of reliable closure techniques, hindered its widespread adoption and progress. Conventional endoscopic tools often fall short in terms of triangulation, traction and degrees of freedom, necessitating the adoption of robotic interventions. Over recent decades, robotic endoscopy has significantly evolved, focusing on both diagnostic and complex therapeutic procedures such as endoscopic sub-mucosal dissection (ESD) and endoscopic full-thickness resection (EFTR). Various robotic platforms demonstrate enhanced safety and efficiency in GI procedures. As the field progresses, the emphasis on clinical validation, advanced training and the exploration of new applications remains crucial. Continuous innovation in robotic technology and endoscopic techniques promises to overcome existing limitations, further revolutionizing the management of GI diseases and improving patient outcomes.

Objectives: To assess the effectiveness of remimazolam against normal saline (placebo) as a sedative agent for endoscopy in a multicenter, randomized, double‐blind, investigator‐initiated phase III controlled trial. Methods: We included 48 Japanese patients undergoing upper gastrointestinal endoscopy. For the procedure, an initial remimazolam dose of 3 mg and additional doses of 1 mg were administered, as determined in the phase II clinical study. The primary study end‐point was the successful sedation rate during gastrointestinal endoscopy, determined as a Modified Observer's Assessment of Alertness/Sedation score ≤4 before the start of endoscopy, the completion of gastrointestinal endoscopy, and two or fewer additional doses per 6 min. Results: The successful endoscopy sedation rates were 91.9% and 9.1% in the remimazolam and placebo groups, respectively (P < 0.01). The time from the end of endoscopy to arousal was 0.0 (0.0–0.0) min for both groups. The number of additional doses required to achieve sedation was lower in the remimazolam group than that in the placebo group (P < 0.01). Conclusions: Remimazolam demonstrated a significantly higher sedation effect during upper gastrointestinal endoscopy in Japanese patients with safe and fast recovery compared with placebo.

Background and Aims: Gastric cancer (GC) is the third cause of cancer mortality worldwide. A screening strategy that combines an upper gastrointestinal endoscopy (UGIE) with a screening colonoscopy may be cost‐effective in intermediate‐risk regions. This study aimed to evaluate the intention to adhere to combined endoscopic screening and assess knowledge of GC symptoms, risk factors, and barriers to screening. Methods: Cross‐sectional study enrolling individuals eligible for CRC screening in northern Portugal, where a populational fecal occult blood test (FOBT) program is implemented. The validated PERCEPT‐PREVENT tool was applied across three groups: (a) not yet invited to CRC screening, (b) FOBT‐positive referred to colonoscopy, and (c) primary colonoscopy screening. Results: A high acceptance rate was observed for combined endoscopic screening (94%; n = 264) [not yet invited to CRC screening 98% (n = 90) vs. FOBT‐positive referred to colonoscopy 90% (n = 103) vs. primary colonoscopy 97% (n = 71); p = 0.017], with the vast majority reporting intention to adhere in the setting of full reimbursement (97%; n = 255). Most respondents were unaware of any possible GC symptom (76%; n = 213), risk factor (73%; n = 205), and UGIE‐related complication (85%; n = 237). Regular follow‐up with the primary care physician (Odds Ratio (OR) 27.59, 95% confidence interval (CI) 2.99–254.57), lower perceived negative health consequences of UGIE (OR 1.40, 95% CI 1.13–1.74), and lower perceived financial burden (OR 2.46, 95% CI 1.04–5.85) were the only factors independently associated with a higher intention to undergo combined screening. Conclusions: Willingness to undergo combined endoscopic screening was notably high and positively impacted by lower perceived barriers. Additional efforts should be undertaken to improve levels of digestive health literacy. [ABSTRACT FROM AUTHOR]

Sedation and analgesia during gastrointestinal (GI) endoscopy increase procedural quality, contributing at the same time to greater patient satisfaction and willingness to undergo the procedure. Although sedation use has been optimized by the advent of efficacious and safe medications, data regarding the minimal criteria for discharge after outpatient endoscopy remain scant. Moreover, the time of discharge after endoscopy can be highly variable, depending not only on the type of procedure and anesthesia administered, but also on postprocedural complications and the patient's comorbidities. To make things even more conflicting, there is neither consensus among various endoscopic societies, concerning the most appropriate discharge strategy, nor a universally established tool that could be incorporated into everyday clinical practice, allowing patients' safe discharge as well as ability to drive. In this context, we conducted a systematic review, aiming to summarize the evidence regarding the available discharge scoring systems after outpatient GI endoscopy with sedation and analgesia administration.

Purpose To investigate the impacts of remimazolam tosilate on gastrointestinal hormones and motility in patients undergoing gastrointestinal endoscopy with sedation. Methods A total of 262 American Society of Anesthesiologists Physical Status I or II patients, aged 18–65 years, scheduled for gastrointestinal endoscopy with sedation, were randomly allocated into two groups (n  = 131 each): the remimazolam tosilate group (Group R) and the propofol group (Group P). Patients in Group R received 0.2–0.25 mg/Kg remimazolam tosilate intravenously, while those in Group P received 1.5–2.0 mg/kg propofol intravenously. The gastrointestinal endoscopy was performed when the Modified Observer's Assessment of Alertness/Sedation scores were ≤3. The primary endpoints included the endoscopic intestinal peristalsis rating by the endoscopist; serum motilin and gastrin levels at fasting without gastrointestinal preparation (T 0), before gastrointestinal endoscopy (T 1), and before leaving the Post Anesthesia Care Unit (T 2); and the incidences of abdominal distension during Post Anesthesia Care Unit. Results Compared with Group P, intestinal peristalsis rating was higher in Group R (P  < .001); Group R showed increased motilin and gastrin levels at T 2 compared with Group P (P  < .01). There was a rise in motilin and gastrin levels at T 1 and T 2 compared with T 0 and at T 2 compared with T 1 in both groups (P  < .01). The incidence of abdominal distension was lower in Group R (P  < .05). Conclusion Compared with propofol used during gastrointestinal endoscopy with sedation, remimazolam tosilate mildly inhibits the serum motilin and gastrin levels, potentially facilitating the recovery of gastrointestinal motility. What is already known on this topic Remimazolam tosilate (RT), as a novel ultrashort-acting benzodiazepine, has been recently used in gastrointestinal endoscopy with sedation. Nevertheless, the effects of RT on gastrointestinal hormones and gastrointestinal motility remain unclear. What this study adds Compared with propofol used in gastrointestinal endoscopy with sedation, RT mildly inhibits serum motilin and gastrin levels and gastrointestinal motility. How this study might affect research, practice, or policy RT sedation for gastrointestinal endoscopy might contribute to recovery of gastrointestinal function. [ABSTRACT FROM AUTHOR]

Most gastric neoplastic lesions appear in patients with gastric premalignant conditions. Here, we present the case of a 75-year-old woman with no prior history of Helicobacter pylori infection, with a big gastric adenoma resected by endoscopic submucosal dissection. Histopathological examination revealed high-grade foveolar dysplasia. Interestingly, surrounding mucosa was normal, without signs of H. pylori infection or gastric preneoplastic conditions. The presented case emphasizes that high-risk gastric lesions may be present within a normal stomach without endoscopic signs of H. pylori infection or premalignant conditions. This underscores the importance of careful examination in regular practice of esophagogastroduodenoscopy, even in low-risk patients.

Abstract Background and Aim Endoscopic submucosal dissection (ESD) is considered the best modality for achieving en bloc resection of larger neoplastic mucosal lesions in the upper and lower gastrointestinal (GI) tract. Multiple devices are available for ESD, and refinements continue to be made to develop devices that improve the safety and efficiency of performing ESD. Submucosal injection with viscous fluids like glycerol, which prolong submucosal expansion, could facilitate the procedure. We aimed to evaluate the safety and performance of the new Erbe HYBRIDknife® flex, which combines electrosurgical dissection with waterjet‐assisted injection in a slim and flexible form factor. Methods In a prospective animal study with six pigs, four endoscopists, each with 10–20 years of experience in ESD, performed 28 esophageal ESDs. One half was performed with physiological saline injectate, the other half with fructose‐added glycerol. Various performance aspects were evaluated on a five‐point scale [5 = best], including dissection properties, handling, and usability. Results No perforations or major bleeding occurred. All resections were performed en bloc, with one technical failure (3.6%, 1 of 28). Performance scores were similar for saline and glycerol (4.5 ± 0.31 vs. 4.5 ± 0.32, P = 0.36), as was dissection speed (13 ± 6.2 mm2/min vs. 15 ± 6.1 mm2/min, P = 0.22). Conclusions We demonstrated that esophageal ESD can be performed safely and rapidly using HYBRIDknife flex, with excellent performance evaluation by the endoscopists. Combining this device with glycerol or saline is precise and effective for ESD, although experience could compensate for the theoretical disadvantage of using normal saline.

In this report, we present the results of a survey of gastrointestinal endoscopists to clarify the factors that influence the use of doctor education systems in gaining product share. Since gastrointestinal endoscopy requires high technical skills and is a business dominated by domestic companies, we felt that it was an appropriate subject for this survey. Olympus holds the top share in this business, but has particularly strong ties with universities, which are educational institutions, and it is believed that the existence of endoscopy as an educational tool contributes to its oligopoly in this field. On the other hand, Fujifilm, which follows Olympus, has pursued a completely opposite strategy of focusing on private practice doctors and combining this with a pricing strategy. However, Olympus's share remains high, and it is suggested that its involvement in doctor education, which bears the learning costs as a part of it, may lead to a decision-making system that does not rely on a pricing strategy and may be a source of competitive advantage. It is expected that the results of this study will help mature industries gain competitive advantages and become a source of new innovation.

Background: Current guidelines advise that patients diagnosed with liver cirrhosis undergo screening through upper gastrointestinal endoscopy to detect esophageal varices (EV). Prophylactic measures should be taken for those with large varices on diagnosis and during follow-up. However, this poses a dual challenge, both social and medical, as the number of cirrhotic patients rises while the availability of endoscopy units remains limited. Aims and Objectives: In this study, we aim to evaluate the diagnostic accuracy of the non-invasive predictors such as spleen size, platelet count (PC), and PC/spleen diameter (PC/SD) ratio for the diagnosis of EV. Materials and Methods: This hospital-based prospective observational study was done in the SDM College of Medical Sciences and Hospital, Dharwad, among 50 patients with cirrhosis of liver. Results: Among the 50 patients studied males pre-dominated the study with 80%. Out of the study population, 70% of the patients had varices. For a cutoff point of PC/SD ratio 916, the sensitivity was 71.42% and specificity was 93.3%. For a cutoff value of PC of 1.32 lakhs, the sensitivity was 71.42%, and the specificity was 73.3%. For a cutoff value of the longest SD of 12.40 cm, the sensitivity was 94.30%, and specificity was 33.3%. Conclusion: These non-invasive predictors can be useful screening tools for the diagnosis of EV. These can be effective for the initiation of prophylactic treatment when the endoscopy facility is not available.

This study aimed to evaluate the efficacy and safety of remimazolam besylate in elderly patients who underwent diagnostic gastrointestinal endoscopy.Patients and Methods: A total of 120 patients aged 60– 75 years were randomly allocated to one of two groups. Remifentanil 0.3μg/kg was used for analgesia. Patients were administered remimazolam besylate 7 mg (R group) or etomidate 0.1 mg/kg combined with 1% propofol 0.5 mg/kg (EP group) for induction, supplemental repeated doses were given as needed. Some time metrics, vital signs, adverse events were evaluated. Patients’ Mini-cog score and recovery questionnaires were compared.Results: Compared to the EP group, the induction time was slightly longer in the R group (1.50 VS 1.15 minutes) (P< 0.05), the time spent in the post-anesthesia care unit (PACU) was shorter (15.17 VS 17.40 minutes) (P< 0.05). Compare with EP group, SBP was lower in R group at T15 and T25 time point, but heart rate was higher in T2, T3, T5 (P< 0.05). The Mini-Cog score was higher after the procedure (2.83 VS 2.58) (P< 0.05). The incidence of respiratory adverse events was higher in the EP group than R group (18.3% VS 5.0%, P < 0.05). The most common adverse event in R group was hiccups. The sedation satisfaction rate and degree of amnesia were higher in the R group (66.7% VS 11.7%) (P < 0.05), and the effect on patient’s life within 24 hours was lower (12.0% VS 30.5%) (P < 0.05).Conclusion: The safety and efficacy of remimazolam besylate are not inferior to those of etomidate combined with propofol, rendering it a safe option for sedation during gastrointestinal endoscopy in ASA I-II elderly patients, but care should be taken to monitor the occurrence of hiccups.Keywords: gastrointestinal endoscopy, anesthesia, remimazolam besylate, etomidate, propofol

Background/Aims Gastric subepithelial tumors (SETs) are often encountered during the upper gastrointestinal endoscopic screening. We assessed the prevalence of gastric SETs and the risk factors for their progression. Methods We reviewed the electronic medical records of 30,754 patients who underwent upper gastrointestinal endoscopic screening at our medical center between January 2013 and December 2016. Results Among the 30,754 patients examined, 599 (1.9%) had gastric SETs. The prevalence increased with age and was 9.56% in patients aged ≥70 years. In total, 262 patients underwent serial endoscopy for more than 6 months. The median age was 68 years (interquartile range [IQR], 61–74), and the number of females was 167 (63.7%). During a median follow-up of 58 months (IQR, 38–75), 22 patients (8.4%) showed significant changes in tumor size. An irregular border (odds ratio, 4.623; 95% confidence interval, 1.093–19.558; p=0.037) was a significant risk factor for progression. Seven patients underwent surgical or endoscopic resections. The pathologies of gastric SETs included leiomyomas (n=3), gastrointestinal stromal tumors (n=2), and lipomas (n=2). Conclusions The prevalence of gastric SETs increases with age. Most gastric SETs do not progress during long-term endoscopic examinations, and the risk of an increase in size is low in asymptomatic small SETs without irregular borders.

Abstract Background The administration of anesthesia during gastrointestinal endoscopy potentially contributes to post-anesthesia cognitive dysfunction (PACD), with detrimental impacts for cognitive function. This study aimed to assess the knowledge, attitudes, and practices (KAP) towards PACD among patients undergoing gastrointestinal endoscopy in Wenzhou region. Methods This cross-sectional study was conducted between June and August 2023, and recruited individuals undergoing gastrointestinal endoscopy. Demographic data and KAP scores were collected through questionnaires. Pearson correlation analysis was applied to evaluate correlations between KAP scores, and logistic regression was utilized to identify influential factors. Results We collected 405 valid questionnaires, with 54.57% being male and 29.88% aged 31–40 years. Mean KAP scores were 13.99 ± 4.80, 16.19 ± 2.35, and 15.61 ± 2.86, respectively (possible range: 0–16, 0–25, and 0–25). Pearson correlation analysis demonstrated significant positive correlations between knowledge and practice (r = 0.209, P

Introduction: Gastrointestinal tuberculosis (TB), specifically gastric TB, is a rare form of extrapulmonary TB. Diagnosis proves challenging with nonspecific signs and symptoms. In this case report, a 22-year-old male came in with complaints of recurrent hematemesis and melena. Case Presentation: We found a submucosal mass with ulceration in the stomach cardia on esophagoduodenoscopy (EGD). The endoscopic ultrasound (EUS) finding was a hypoechoic submucosal lesion with a clear margin; specimens were taken using fine needle aspiration (FNA) for further histopathological examination. The result indicated granuloma of Mycobacterium Tuberculosis in pathology, suggesting that the diagnosis was gastric TB. The patient was then treated with antitubercular therapy regimen for 9 months. The previously documented mass in the stomach cardia was no longer visible on the follow-up endoscopy examination, and the patient was considered cured. Conclusion: This case shows that gastric tuberculosis should be considered in patients with gastrointestinal symptoms, especially those living in TB endemic regions. Endoscopic examinations, such as EGD and EUS, may aid in the diagnosis of gastric tuberculosis.

Abstract Introduction Further clinical validation is required to determine whether transcutaneous electrical acupoint stimulation (TEAS) can replace opioids and be used in combination with remimazolam for sedation during gastrointestinal endoscopy. Methods A total of 108 outpatients who underwent diagnostic gastrointestinal endoscopy were randomly divided into three groups: fentanyl plus remimazolam group (group C), TEAS plus remimazolam group (group E), and placebo-TEAS plus remimazolam group (group P). The assessments of patient satisfaction, physician satisfaction, and pain scale score during the examination constituted the primary endpoints of the study. The secondary endpoints were the time of recovery, recovery of normal behavioral function and discharge, incidence of adverse reactions, and dose of remimazolam. Results Compared with group C, group E had a greater median score for patient satisfaction at follow-up and a slightly lower median score for physician satisfaction. The pain score of group E was slightly greater than that of group C, but the difference was not significant. However, in group C, the incidence of hypoxemia, the rate of nausea and the severity of vertigo were greater, and the number of patients discharged and resuming normal behavioral function was greater than those in the other two groups. The dose of remimazolam in group C and group E was less than that in group P. Conclusions TEAS combined with moderate sedation of remimazolam can provide an ideal sedative effect, which preferably suppresses discomfort caused by gastrointestinal endoscopy and has fewer sedation-related complications.

BACKGROUND: Anthracosis is a disease generally considered to be in the lungs resulting from exposure to industrial dust in the workplace. Esophageal anthracosis is a fairly rare phenomenon and shows a strong correlation with tuberculosis. Moreover, esophageal involvement in tuberculosis is also rare. We here present an extremely rare case in which follow-up gastroesophageal endoscopy revealed a mass with a sunken, black area in the center and raised ring-like pattern in the surrounding mucosa resembling malignant melanoma. Uncovering the patients tuberculosis history finally avoided a misdiagnosis or overtreatment. CASE PRESENTATION: A 67-year-old male patient was admitted to the hospital due to repeated chest pain for 1 month. Endoscopic ultrasonography and contrast-enhanced CT scans revealed a mass adjacent to the esophageal wall with unclear boundaries. Aspiration biopsy confirmed that esophageal tuberculosis was caused by nearby mediastinal tuberculous lymphadenitis. After a standard anti-tuberculosis treatment regimen, the patient achieved a favorable prognosis. The follow-up gastroesophageal endoscopy showed a sunken black lesion with elevated peripheral mucosa replacing the original tuberculous mass, which was thought to be anthracosis, a disease that rarely occurs in the esophagus. CONCLUSION: The diagnosis of tuberculosis should be taken into consideration when a submucosal mass appears in the middle part of the esophagus. Endoscopic ultrasonography can effectively contribute to a definite diagnosis. Moreover, this is the first case of esophageal anthracosis observed only 1 year after the treatment of tuberculosis, indicating esophageal anthracosis can be a short-term disease. The traction of the reduction of tubercular mediastinal lymph nodes after anti-tuberculosis treatment may create a circumstance for pigmentation or dust deposition.

Multimodal retrieval has gained much attention lately due to its effectiveness over uni-modal retrieval. For instance, visual features often under-constrain the description of an image in content-based retrieval; however, another modality, such as collateral text, can be introduced to abridge the semantic gap and make the retrieval process more efficient. This article proposes the application of cross-modal fusion and retrieval on real in vivo gastrointestinal images and linguistic cues, as the visual features alone are insufficient for image description and to assist gastroenterologists. So, a cross-modal information retrieval approach has been proposed to retrieve related images given text and vice versa while handling the heterogeneity gap issue among the modalities. The technique comprises two stages: (1) individual modality feature learning; and (2) fusion of two trained networks. In the first stage, two self-organizing maps (SOMs) are trained separately using images and texts, which are clustered in the respective SOMs based on their similarity. In the second (fusion) stage, the trained SOMs are integrated using an associative network to enable cross-modal retrieval. The underlying learning techniques of the associative network include Hebbian learning and Oja learning (Improved Hebbian learning). The introduced framework can annotate images with keywords and illustrate keywords with images, and it can also be extended to incorporate more diverse modalities. Extensive experimentation has been performed on real gastrointestinal images obtained from a known gastroenterologist that have collateral keywords with each image. The obtained results proved the efficacy of the algorithm and its significance in aiding gastroenterologists in quick and pertinent decision making. [ABSTRACT FROM AUTHOR]

Background: The administration of anesthesia during gastrointestinal endoscopy potentially contributes to post-anesthesia cognitive dysfunction (PACD), with detrimental impacts for cognitive function. This study aimed to assess the knowledge, attitudes, and practices (KAP) towards PACD among patients undergoing gastrointestinal endoscopy in Wenzhou region. Methods: This cross-sectional study was conducted between June and August 2023, and recruited individuals undergoing gastrointestinal endoscopy. Demographic data and KAP scores were collected through questionnaires. Pearson correlation analysis was applied to evaluate correlations between KAP scores, and logistic regression was utilized to identify influential factors. Results: We collected 405 valid questionnaires, with 54.57% being male and 29.88% aged 31–40 years. Mean KAP scores were 13.99 ± 4.80, 16.19 ± 2.35, and 15.61 ± 2.86, respectively (possible range: 0–16, 0–25, and 0–25). Pearson correlation analysis demonstrated significant positive correlations between knowledge and practice (r = 0.209, P < 0.001), attitude and practice (r = 0.233, P < 0.001), and knowledge and attitude (r = 0.328, P < 0.001). Multivariate logistic regression revealed negative associations of opting for standard gastrointestinal endoscopy (without anesthesia) with knowledge (OR = 0.227, 95%CI: 0.088–0.582, P = 0.002) and practice scores (OR = 0.336, 95%CI: 0.154–0.731, P = 0.006). Additionally, the presence of cognitive-related diseases or symptoms before undergoing gastrointestinal endoscopy was negatively associated with knowledge scores (OR = 0.429, 95%CI: 0.225–0.818, P = 0.010). Conclusion: Patients undergoing gastrointestinal endoscopy demonstrated good knowledge, neutral attitudes, and moderate practices regarding PACD. Educational interventions and behavior modification are recommended, particularly for individuals with lower monthly income, undergoing standard gastrointestinal endoscopy, or experiencing cognitive-related conditions.

Purpose: Despite annual endoscopy, patients with metachronous remnant gastric cancer (MRGC) following proximal gastrectomy (PG) are at times ineligible for endoscopic resection (ER). This study aimed to clarify the clinical risk factors for ER inapplicability. Materials and Methods: We reviewed the records of 203 patients who underwent PG for cT1 gastric cancer between 2006 and 2015. The remnant stomach was categorized as a pseudofornix, corpus, or antrum. Results: Thirty-two MRGCs were identified in the 29 patients. Twenty MRGCs were classified as ER (ER group, 62.5%), whereas 12 were not (non-ER group, 37.5%). MRGCs were located in the pseudo-fornix in 1, corpus in 5, and antrum in 14 in the ER group, and in the pseudofornix in 6, corpus in 4, and antrum in 2 in the non-ER group (P=0.019). Multivariate analysis revealed that the pseudo-fornix was an independent risk factor for non-ER (P=0.014). In the non-ER group, MRGCs at the pseudo-fornix (n=6) had more frequent undifferentiated-type histology (4/6 vs. 0/6), deeper (≥pT1b2; 6/6 vs. 2/6) and nodal metastasis (3/6 vs. 0/6) than non-pseudo-fornix lesions (n=6). We examined the visibility of the region developing MRGC on an annual follow-up endoscopy one year before MRGC detection. In seven lesions at the pseudofornix, visibility was only secured in two (28.6%) because of food residues. Of the 25 lesions in the non-pseudo-fornix, visibility was secured in 21 lesions (84%; P=0.010). Conclusions: Endoscopic visibility increases the chances of ER applicability. Special preparation is required to ensure the complete clearance of food residues in the pseudo-fornix. [ABSTRACT FROM AUTHOR]

Background: Obesity is a disease with high prevalence worldwide, and its incidence is increasing, especially in middle- to high-income countries. Its pathophysiology is related to intestinal hormonal regulation and various gastrointestinal conditions. Introduction: The gastroenterologist plays a crucial role in treating this disease through specialized interventions such as bariatric endoscopy, which contribute to weight loss and reduce comorbidities associated with this condition. Additionally, as more patients undergo weight loss procedures, understanding the adjunctive medical treatment in bariatric procedures becomes essential. This review presents the key elements that the gastroenterologist should consider in managing obesity based on the most recent literature. Conclusions: There are unmet treatment needs for patients with obesity, among which bariatric endoscopic procedures are a reality when conducted in conjunction with other multidisciplinary approaches.

In gastrointestinal endoscopy, polyp identification is an important step in the fight against colorectal cancer. Using the cutting-edge BASNet model—a deep learning architecture for picture segmentation—we provide a web-based polyp identification method in this study. Endoscopy pictures may be uploaded to the system and evaluated by the BASNet model to detect and highlight possible polyps. In order to correctly separate polyps from endoscopic pictures, the suggested method makes use of the BASNet model. This model combines a prediction module with a residual refinement module. The segmentation is refined to provide a fine label map by the residual refinement module, after the prediction module has provided a coarse one. In order to reliably and accurately forecast where polyps are located within the pictures, the system makes use of these components. Model loading for rapid inference, real-time prediction of polyp masks, and image preprocessing to guarantee consistency in input data are key components of the system. In order to help medical professionals intervene quickly and improve patient outcomes, the technology gives users instant feedback on polyp diagnosis. [ABSTRACT FROM AUTHOR]

Propofol has a favourable efficacy profile in gastrointestinal endoscopic procedures, however adverse events remain frequent. Emerging evidence supports remimazolam use in gastrointestinal endoscopy. This systematic review and meta-analysis compares remimazolam and propofol, both combined with a short-acting opioid, for sedation of adults in gastrointestinal endoscopy. We searched MEDLINE, Embase, and Cochrane databases for randomised controlled trials comparing efficacy-, safety-, and satisfaction-related outcomes between remimazolam and propofol, both combined with short-acting opioids, for sedation of adults undergoing gastrointestinal endoscopy. We performed sensitivity analyses, subgroup assessments by type of short-acting opioid used and age range, and meta-regression analysis using mean patient age as a covariate. We used R statistical software for statistical analyses. We included 15 trials (4516 subjects). Remimazolam was associated with a significantly lower sedation success rate (risk ratio [RR] 0.991; 95% confidence interval [CI] 0.984–0.998; high-quality evidence) and a slightly longer induction time (mean difference [MD] 9 s; 95% CI 4–13; moderate-quality evidence), whereas there was no significant difference between the sedatives in other time-related outcomes. Remimazolam was associated with significantly lower rates of respiratory depression (RR 0.41; 95% CI 0.30–0.56; high-quality evidence), hypotension (RR 0.43; 95% CI 0.35–0.51; moderate-quality evidence), hypotension requiring treatment (RR 0.25; 95% CI 0.12–0.52; high-quality evidence), and bradycardia (RR 0.42; 95% CI 0.30–0.58; high-quality evidence). There was no difference in patient (MD 0.41; 95% CI –0.07 to 0.89; moderate-quality evidence) and endoscopist satisfaction (MD –0.31; 95% CI –0.65 to 0.04; high-quality evidence) between both drugs. Remimazolam has clinically similar efficacy and greater safety when compared with propofol for sedation in gastrointestinal endoscopies. [ABSTRACT FROM AUTHOR]
