Routine upper gastro-intestinal tract endoscopy before elective cholecystectomy for symptomatic gallstones-justified.

Gallstones are common in Western countries and increasing in developing countries through adoption of western lifestyle. Gallstones may cause life-threatening complications, including acute cholecystitis, acute cholangitis, and acute pancreatitis. Cholecystectomy is the treatment of choice for symptomatic gallstones. Presentation of symptomatic gallstones may be indistinguishable from that of other upper gastro-intestinal tract (UGI) pathologies. Some surgeons routinely perform preoperative UGI endoscopy to diagnose and treat concomitant UGI pathology. A prospective cross-sectional observational study was undertaken at University of Pretoria teaching hospitals to evaluate this practice. Patients aged 18 years and older, with symptomatic gallstones but did not satisfy Tokyo guidelines for acute cholecystitis were recruited. UGI endoscopy was performed before cholecystectomy. There were 124 patients, 110 (88.7%) females and 14 (11.3%) males, mean age 44.0 (13.2) (range: 22-78) years. Most common symptoms were right upper quadrant (RUQ) pain (87%), epigastric pain (59.7%), nausea (58.1%) and vomiting (47.9%). Clinically, 80% had RUQ tenderness and 52.4% epigastric tenderness. UGI endoscopy found 35.4% pathology, 28.2% were active, and comprised acute gastritis (27.4%), peptic ulcers (4.8%), duodenitis (3.2%) and oesophagitis (2.4%). Twelve patients had more than one pathology. This warranted treatment before elective cholecystectomy and justifies the practice of routine preoperative UGI endoscopy.

Upper Gastrointestinal Endoscopy by Pediatric Surgeons: Our Early Experience.

Introduction: Pediatric upper gastrointestinal (UGI) endoscopy is an important procedure in the management of gastrointestinal pathologies. Conventionally, it has been the forte of medical gastroenterologists. However, unlike adults, the availability of pediatric gastroenterologists is limited, especially during emergency hours. We present our early experience of UGI endoscopy done by the department of pediatric surgery. Aims: The aim of this study was to study the feasibility and benefits of UGI endoscopy by pediatric surgeons. Materials and Methods: A retrospective descriptive study was carried out by the department of pediatric surgery of a tertiary-level medical college, from January 2017 to January 2022. Data were collected from electronic and physical medical records. Parameters included age, gender, indication for endoscopy, and procedures done endoscopically or based on endoscopic findings and complications. Results: One hundred and thirty endoscopies were done in 95 patients aged 1-16 years, from January 2017 to January 2022. The most common indication for UGI endoscopy was esophageal stricture (71 procedures in 41 patients), followed by UGI foreign body (18 cases). All other indications were mostly diagnostic, other than four patients with achalasia. Thirty of these patients underwent UGI endoscopy as an emergency procedure. Seventeen patients were followed through or had added procedures, with UGI endoscopy. There was one perforation when dilating an esophageal stricture who responded to conservative management. Conclusion: UGI endoscopy is a valuable diagnostic and therapeutic procedure, which can be performed by pediatric surgeons after necessary training. It supplements decision-making in management, avoids waste of time in referring, avoids additional anesthesia, and is valuable in emergencies.

Correlation of non-invasive parameters with upper gastrointestinal endoscopy findings for presence and grading of gastroesophageal varices in liver cirrhosis patients.

Background: Development of esophageal varices is one of the major complications of liver cirrhosis, and endoscopy is used to see the presence, grading, and long-term monitoring of esophageal varices which is an invasive and unpleasant procedure. There is no adequate data available showing noninvasive methods can be used for the same. Methods: Seventy patients with liver cirrhosis participated in the study. Factors like portal vein diameter, spleen size, platelet count, serum bilirubin, Child-Pugh score, prothrombin time (PT), and PT INR were observed and correlated endoscopically with the presence and grading of esophageal varices in all patients. Results: The platelet count, portal vein diameter, serum bilirubin, spleen bipolar diameter, and PT had statistically significant correlations with the presence of varices. Among them, platelet count, portal vein diameter, and serum bilirubin also had statistically significant correlations with the grading of varices. Monitoring of these noninvasive parameters can help in monitoring variceal growth. Conclusions: Noninvasive parameters can be used effectively to predict the presence and grading of esophageal varices and at the same time keep the rate of undiagnosed varices acceptably low. By using noninvasive parameters, patients can be benefited by decreasing the requirement of repeated endoscopic evaluation which is an unpleasant procedure and availability is also limited.

Health-related quality of life in patients with dyspepsia presenting at the University of Benin Teaching Hospital, Benin City, South-South Nigeria: a cross-sectional study.

Introduction: Health-related quality of life (HRQoL) examines the impact of the symptoms of dyspepsia on the daily life of sufferers. There are a few published studies related to HRQoL of persons with dyspepsia in Africa. Methods: this was a hospital-based cross-sectional study involving 324 dyspeptic patients referred for upper gastrointestinal endoscopy to the University of Benin Teaching Hospitals (UBTH) The ROME IV criteria were used to recruit patients with dyspepsia. The short form Nepean Dyspepsia Index (SF NDI) was used to assess HRQoL in all participants. Upper gastrointestinal endoscopy was performed on all 324 dyspeptic patients. Results: the mean age of patients was 47.6 ± 15.6 years. Three hundred (92.6%) patients had significantly impaired HRQoL with an SF NDI mean score of 31.3 ± 9.1. Interference with daily activities and eating and drinking subdomains were more impaired than other subdomains of HRQoL (p < 0.001). There was no statistical difference between the impaired HRQoL in patients with functional dyspepsia and organic dyspepsia (p = 0.694). Among patients with organic dyspepsia, those with upper gastrointestinal cancers had significantly worse HRQoL SF NDI mean (sd) scores (39.7 ± 5.9) compared with patients with gastritis, peptic ulcer disease and GERD with (30.3 ± 9.2, 31.5 ± 9.7 and 32.9 ± 7.1 respectively) (p = 0.01). Conclusion: health-related quality of life is significantly impaired in patients with dyspepsia and those with upper gastrointestinal cancers having overall worse scores. The physical, social and psychological well-being of a majority of patients with dyspepsia in South-South Nigeria is negatively affected by dyspepsia.

Management of a Rare Challenging Case of Duodenal Ampullary Lipoma.

Duodenal lipoma is a very rare entity with limited case reports present in literature. But duodenal ampullary lipomas are even more rare in nature. Owing to the recent advances in endoscopy and modern imaging techniques, more cases are being diagnosed and treated. However, challenge lies in performing a less invasive and least morbid procedures to treat them surgically in such complex location of tumour. To study the diagnosis and treatment of duodenal ampullary lipoma in a young male patient and challenges faced during surgical management. A 15-year-old young boy presented to us with complaints of intermittent upper gastrointestinal bleed and jaundice since last 2 months. At admission, his serum haemoglobin was 3 g% for which he was transfused 3 units of packed blood cells for optimization. On further evaluation, CT scan abdomen revealed 71 × 49 mm large heterogeneous mass in D3 segment of duodenum causing duodeno-duodenal intussusception involving D1 and D2 segment along with ampullary region with mass being the lead point. There was compression of CBD with dilatation measuring 11 mm in diameter and mild IHBR dilatation. UGIE revealed narrowing at D1-D2 junction due to polypoidal lesion with overlying smooth mucosa with no active bleeding point identified. His blood parameters were normal except for low haemoglobin (before blood transfusion) and total serum bilirubin of 2.3 mg/dl.He was optimized for surgery and underwent exploratory laparotomy with duodenotomy at D2 with mass excision of 7 × 5 cm sessile polyp with base over ampulla followed by plastic repair of sphincter of Oddi (pancreas preserving procedure). He was started on oral liquids on POD 3 and was discharged on normal diet by POD 7 with an uneventful recovery. Result of histopathological report revealed, on gross cut section, the presence of mass of 7 × 5 × 3 cm size with smooth mucosa and fibrofatty tissue. On microscopic examination, diagnosis of submucosal lipomatous polyp was made. Our case report indicated duodenal ampullary lipoma is extremely rare entity. The symptoms are nonspecific and CT scan abdomen is the first investigation of choice for diagnosis. The treatment depends on the patient's condition as well as the size and position of the tumour. In our case report, the tumour base was exactly at the level of ampulla where we performed complex procedure of local excision of mass with sphincteroplasty avoiding major Whipple procedure for such benign condition. It provided rapid postoperative recovery to the patient.

Chronological Trend of Opportunistic Endoscopic Screening for Gastric Cancer and Atrophic Gastritis.

BACKGROUND: Opportunistic endoscopic screening for gastric cancer was initiated in 2004 at our institute. We investigated chronological trends in gastric cancer detection rates based on individual characteristics and atrophic gastritis prevalence. METHODS: Overall, 15,081 asymptomatic individuals aged ≥40 years without a medical history of gastric cancer underwent first-time esophagogastroduodenoscopy in our institute between February 2004 and December 2017. We retrospectively investigated individual characteristics and endoscopic diagnoses by period (early period: 2004-2007, middle period: 2008-2012, and late period: 2013-2017), clarified the long-term detection rate and the characteristics of endoscopic screening-detected gastric cancer, and evaluated the relationship between gastric cancer and atrophic gastritis. RESULTS: Gastric cancer detection rates in the early, middle, and late periods were 1.01% (76/7,503, men/women: 4,360/3,143, average age: 59.4 years, prevalence of atrophic gastritis: 72%), 0.69% (40/5,820, men/women: 3,668/2,152, average age: 56.8 years, prevalence of atrophic gastritis: 48%), and 0.46% (8/1,758, men/women: 1,083/675, average age: 58.7 years, prevalence of atrophic gastritis: 37%), respectively. Multivariate analysis revealed that male sex (odds ratio 1.92, 95% confidence interval 1.28-2.95), age ≥75 years (2.73, 95% CI 1.32-5.05), and atrophic gastritis (C1-C3: 2.21, 1.36-3.73, O1-O3: 5.36, 3.17-9.30) were significantly associated with the incidence of gastric cancer. CONCLUSIONS: The gastric cancer detection rate and atrophic gastritis prevalence have decreased over time. However, continuing endoscopic screening is important, especially for those at a high risk of developing gastric cancer complicated by severe atrophic gastritis.

Quality Standards in Upper Gastrointestinal Endoscopy: Can Deep Sedation Influence It?

Introduction: According to the guideline published by ESGE/UEG, a high-quality esophagogastroduodenoscopy (EGD) implies the application of some criteria that enable better healthcare outcomes. Although intra-procedural performance measures are dependent on patient factors, there is no reference to sedation practices in the guideline mentioned above. Objective: This study aimed to evaluate whether deep sedation influences EGD performance measures established by ESGE/UEG. Methods: This was a cross-sectional study, with a prospective enrollment, that considered for inclusion consecutive patients referred for EGD. Two questionnaires were used to assess performance measures and patient satisfaction after EGD. Results: Sedation had a statistically significant impact on most quality indicators, including complete examination (77.2% without sedation vs. 97.8% with sedation), inspection time (6.17 ± 3.45 vs. 8.39 ± 2.67 min), photodocumentation (78% vs. 97.8%), biopsies (39.3% vs. 60.7%), and patient satisfaction (5.42 ± 2.93 vs. 9.1 ± 1.19). The main reason for an incomplete procedure was patient intolerance (82.6%). Discussion: Deep sedation of patients submitted to EGD proved to be a determinant in the applicability of the ESGE/UEG quality indicators. Patient intolerance was eliminated in the group with sedation, enhancing procedure completeness, adequate pathology identification, management, and consequently, the effectiveness of the exam. Conclusion: Sedation administration should be considered in patients undergoing EGD since it ensures a high-quality procedure.

Introdução: Uma endoscopia digestiva alta (EDA) de qualidade proporciona melhores resultados em termos de saúde e implica a aplicação dos critérios descritos pelas recomendações da ESGE/UEG. Embora os critérios perprocedimento sejam dependentes da colaboração e tolerância do doente, não está explicito o papel da anestesia. Objetivos: Este estudo pretende avaliar se o recurso a anestesia influencia o cumprimento dos critérios de qualidade para a EDA publicados pela ESGE/UEG. Materiais e métodos: Estudo transversal, com recrutamento prospetivo, que incluiu pacientes consecutivamente encaminhados para realização de EDA. Foram utilizados 2 questionários para avaliar medidas de desempenho e satisfação dos pacientes após realização de EDA. Resultados: A anestesia teve um impacto estatisticamente significativo na maioria dos indicadores de qualidade: exame completo (77,2% sem anestesia vs. 97,8% com anestesia); tempo de inspeção (6,17 ± 3,45 vs. 8,39 ± 2,67 minutos); fotodocumentação (78% vs. 97,8%); biópsias (39,3% vs. 60,7%); satisfação do paciente (5,42 ± 2,93 vs. 9,1 ± 1,19). O principal motivo para um procedimento incompleto foi a intolerância do paciente (82,6%). Discussão: A sedação profunda dos doentes submetidos a EDA provou ser determinante na aplicabilidade dos critérios de qualidade da ESGE/UEG. Eliminando por completo a intolerância por parte do doente, proporcionou a realização de exames completos, com correta identificação e gestão de patologias, potenciando assim a efetividade do exame. Conclusão: A administração de anestesia deve ser ponderada, sempre que possível, nos doentes submetidos a EDA, visto que permite garantir a alta qualidade do procedimento.

Quality assessment of online patient information on upper gastrointestinal endoscopy using the modified Ensuring Quality Information for Patients tool.

INTRODUCTION: Websites and online resources are increasingly becoming patients' main source of healthcare information. It is paramount that high quality information is available online to enhance patient education and improve clinical outcomes. Upper gastrointestinal (UGI) endoscopy is the gold standard investigation for UGI symptoms and yet little is known regarding the quality of patient orientated websites. The aim of this study was to assess the quality of online patient information on UGI endoscopy using the modified Ensuring Quality Information for Patients (EQIP) tool. METHODS: Ten search terms were employed to conduct a systematic review. for each term, the top 100 websites identified via a Google search were assessed using the modified EQIP tool. High scoring websites underwent further analysis. Websites intended for professional use by clinicians as well as those containing video or marketing content were excluded. FINDINGS: A total of 378 websites were eligible for analysis. The median modified EQIP score for UGI endoscopy was 18/36 (interquartile range: 14-21). The median EQIP scores for the content, identification and structure domains were 8/18, 1/6 and 9/12 respectively. Higher modified EQIP scores were obtained for websites produced by government departments and National Health Service hospitals (p=0.007). Complication rates were documented in only a fifth (20.4%) of websites. High scoring websites were significantly more likely to provide balanced information on risks and benefits (94.6% vs 34.4%, p<0.001). CONCLUSIONS: There is an immediate need to improve the quality of online patient information regarding UGI endoscopy. The currently available resources provide minimal information on the risks associated with the procedure, potentially hindering patients' ability to make informed healthcare decisions.

Eosinophilic esophagitis in children: A cross-sectional study from a tertiary care center.

Background and Aim: The prevalence of eosinophilic esophagitis (EoE) is rising in the West. However, data from the Indian subcontinent is limited. In this prospective cross-sectional study, we estimated the prevalence of EoE among children undergoing elective upper gastrointestinal endoscopy (UGIE). Methods: We enrolled 200 consecutive children (123 boys, median age 10.25 years [interquartile range 8.25-14.5]) between March 2020 and November 2022 at our center. Clinical characteristics, endoscopic findings, and laboratory parameters were noted. A total of 12 mucosal biopsies (3 each from the middle and lower third of the esophagus, stomach, and duodenum) were obtained. EoE was diagnosed if the peak eosinophil count was ≥15/high-power field (HPF) in absence of gastric and duodenal eosinophilia. Results: The commonest indications for UGIE were gastroesophageal reflux disease-like symptoms (29%), inflammatory bowel disease (22.5%), celiac disease (15%), and abdominal pain (13%). EoE was detected in seven children, suggesting an overall prevalence of 3.5%. Of the 20 children evaluated for dysphagia, 4 (20%) had EoE. Also, two of three (67%) children presented with food bolus impaction along with dysphagia had EoE. Of the seven children with EoE, three (43%) had bronchial asthma, two (28.5%) had peripheral eosinophilia, and one (14%) had elevated serum IgE. Trachealization and linear furrows were found in 57% and 71% cases, respectively. Four children received high-dose proton pump inhibitor (PPI) for 12 weeks, two received PPI+ stricture dilatation, and one received systemic steroids. All achieved clinical, endoscopic, and histopathological remission. Conclusion: Hospital-based prevalence of EoE among children undergoing elective UGIE was 3.5%. EoE patients had favorable outcomes with PPI.

Effect of remimazolam vs propofol in high-risk patients undergoing upper gastrointestinal endoscopy: a non-inferiority randomized controlled trial.

BACKGROUND: Procedural sedation is essential for optimizing upper gastrointestinal endoscopy, particularly in high-risk patients with multiple underlying diseases. Respiratory and circulatory complications present significant challenges for procedural sedation in this population. This non-inferiority randomized controlled trial aims to investigate the safety and comfort of remimazolam compared to propofol for procedural sedation during upper gastrointestinal endoscopy in high-risk patients. METHODS: A total of 576 high-risk patients scheduled to undergo upper gastrointestinal endoscopy are planned to be enrolled in this study and randomly allocated to either the remimazolam or propofol group. The primary outcome measure is a composite endpoint, which includes (1) achieving a Modified Observer's Alertness/Sedation scale (MOAA/S) score ≤ 3 before endoscope insertion, (2) successful completion of the endoscopic procedure, (3) the absence of significant respiratory instability during the endoscopy and treatment, and (4) the absence of significant circulatory instability during the examination. The noninferiority margin was 10%. Any adverse events (AEs) that occur will be reported. DISCUSSION: This trial aims to determine whether remimazolam is non-inferior to propofol for procedural sedation during upper gastrointestinal endoscopy in high-risk patients, regarding success rate, complication incidence, patient comfort, and satisfaction.

Letter to editor 'Non-invasive model for predicting high-risk esophageal varices based on liver and spleen stiffness'.

This letter to the editor relates to the study entitled "Non-invasive model for predicting high-risk esophageal varices based on liver and spleen stiffness". Acute bleeding caused by esophageal varices is a life-threatening complication in patients with liver cirrhosis. Due to the discomfort, contraindications, and associated complications of upper gastrointestinal endoscopy screening, it is crucial to identify an imaging-based non-invasive model for predicting high-risk esophageal varices in patients with cirrhosis.

A Case of Gastric Perforation Caused by Excessive Insufflation during Upper Gastrointestinal Endoscopy: Nonoperative Management.

Introduction: Upper gastrointestinal endoscopy is used to diagnose and treat upper gastrointestinal diseases, but it can also cause complications, including perforation. Perforation is a serious complication, so it is important to be aware of the risk factors in advance and to take precautions to prevent it. Case Presentation: We report a case of gastric perforation caused by excessive insufflation during upper gastrointestinal endoscopy in a 64-year-old man with a history of multiple active gastric ulcers. During the endoscopy, the patient did not cooperate and insufflation was performed for a prolonged period of time. This led to a mucosal laceration and a hole suspected to be a perforation on the lesser curvature of the gastric body. The patient was treated nonsurgically with fasting, intravenous fluids, antibiotics, intravenous proton pump inhibitors, and blood transfusions. No leakage was observed on the follow-up computed tomography scan, and the perforation site was completely healed 2 months later. Conclusion: In this case, the patient was successfully treated with conservative therapy alone. The treatment of gastric perforation caused by endoscopy has shifted toward conservative therapy in recent years.

Gastrointestinal: Distal esophageal squamous papillomatosis in a healthy 47-year-old man.

A 47-year-old man with a background history of gastroesophageal reflux disease (GERD) and seasonal asthma underwent a gastroscopy for further investigation. Endoscopy revealed numerous polypoid lesions diffusely distributed in the lower third of the esophagus, with histology revealing squamous papilloma with occasional intraepithelial lymphocytes. The diagnosis was esophageal squamous papillomatosis (ESP), which is a rare condition characterized by exophytic and circumferential projections with friable mucosa diffusely spread through the esophagus with unclear etiology and malignancy risk.

Utilidad de la endoscopia intraoperatoria en cirugía esofagogástrica / The utility of intraoperative endoscopy in esophagogastric surgery

La endoscopia flexible (EF) es un procedimiento de gran utilidad para el manejo diagnóstico y terapéutico de lesiones del tracto digestivo superior. A pesar de que su uso intraoperatorio se ha extendido con el paso de los años, su empleo por parte de cirujanos es aún limitado en nuestro medio. Las oportunidades de capacitación en EF varían ampliamente entre instituciones, especialidades y países. La endoscopia intraoperatoria (EIO) presenta ciertas peculiaridades que aumentan su complejidad respecto a la EF estándar. La realización de EIO repercute positivamente en los resultados quirúrgicos aportándoles seguridad y calidad así como disminución de las complicaciones asociadas a estas técnicas. Debido a sus innumerables ventajas, su uso intraoperatorio por parte de cirujanos es actualmente un proyecto vigente en muchos países y forma parte de un futuro próximo en otros, extendiéndose su uso dentro de la especialidad de cirugía general gracias a la creación de proyectos de formación mejor estructurados. En este manuscrito se realiza una revisión y puesta al día de las indicaciones y utilidades de la endoscopia digestiva alta intraoperatoria en la cirugía esofagogástrica. (AU)

Flexible endoscopy (FE) plays a major role in the diagnosis and treatment of gastrointestinal disease. Although its intraoperative use has spread over the years, its use by surgeons is still limited in our setting. EF training opportunities are different among many institutions, specialties, and countries. Intraoperative endoscopy (IOE) presents peculiarities that increase its complexity compared to standard EF. IOE has a positive impact on surgical results, due to increased safety and quality, as well as a reduction in the complications. Due to its innumerable advantages, its intraoperative use by surgeons is currently a current project in many countries and is part of the near future in others because of the creation of better structured training projects. This manuscript reviews and updates the indications and uses of intraoperative upper gastrointestinal endoscopy in esophagogastric surgery. (AU)

The Importance of Artificial Intelligence in Upper Gastrointestinal Endoscopy.

Recently, there has been a growing interest in the application of artificial intelligence (AI) in medicine, especially in specialties where visualization methods are applied. AI is defined as a computer's ability to achieve human cognitive performance, which is accomplished through enabling computer "learning". This can be conducted in two ways, as machine learning and deep learning. Deep learning is a complex learning system involving the application of artificial neural networks, whose algorithms imitate the human form of learning. Upper gastrointestinal endoscopy allows examination of the esophagus, stomach and duodenum. In addition to the quality of endoscopic equipment and patient preparation, the performance of upper endoscopy depends on the experience and knowledge of the endoscopist. The application of artificial intelligence in endoscopy refers to computer-aided detection and the more complex computer-aided diagnosis. The application of AI in upper endoscopy is aimed at improving the detection of premalignant and malignant lesions, with special attention on the early detection of dysplasia in Barrett's esophagus, the early detection of esophageal and stomach cancer and the detection of H. pylori infection. Artificial intelligence reduces the workload of endoscopists, is not influenced by human factors and increases the diagnostic accuracy and quality of endoscopic methods.

Iatrogenic orbital hematoma: an exceptional complication of upper gastrointestinal endoscopy.

Iatrogenic orbital hematoma is a rare event, most often manifested by a painful exophthalmos that could compromise the patient's visual prognosis. We report the case of a 51-year-old female patient with a history of non-ischemic dilated cardiomyopathy and high blood pressure, who developed a painful exophthalmos following an upper gastrointestinal sedation-free endoscopy. The diagnosis of an intra-orbital hematoma was made by computed tomographic scan and a conservative attitude was adopted after a thorough ophthalmological examination. Upper endoscopy may trigger this condition in the presence of pre-existing predisposing factors such as blood clotting disorders, high blood pressure or vascular malformation. This case highlights an uncommon complication of a commonly performed endoscopy that endoscopists should be aware of to provide safe and optimal examination.

A complication called iatrogenic orbital hematoma is a rare occurrence that can potentially harm a patient's vision. We report a 51-year-old patient who experienced a painful bulging of her eye after undergoing an upper endoscopy (a common procedure to look inside the upper digestive tract) without sedation. A CT scan helped doctors diagnose the problem and after a thorough examination, the condition resolved by itself. This case shows that upper endoscopy can lead to complications and endoscopists should be aware of this possibility to make sure the procedure is safe and successful.

Efficacy and Safety of Different Doses of Remimazolam Tosilate Applied in Upper Gastrointestinal Endoscopy: A Prospective Randomized Controlled Double-Blind Trial.

Background: Remimazolam is a novel benzodiazepine narcotic. When used for gastrointestinal endoscopy or bronchoscopy, it provides adequate sedation and rapid recovery. However, studies on the optimal initial loading dose of remimazolam remain inadequate. Therefore, we conducted a randomized controlled clinical trial to investigate the efficacy and safety of different doses of remimazolam applied in upper gastrointestinal endoscopy. Methods: A total of 218 patients scheduled for upper gastrointestinal endoscopy were included in our trial and divided into experimental and control groups: the experimental groups were the remimazolam groups (R1 of 0.2 mg/kg, R2 of 0.3 mg/kg, and R3 of 0.4 mg/kg), and the control group was the propofol group. Following a single injection of trial drugs during the induction period, operational requirements were evaluated based on MOAA/S scores. When the sedation was successfully achieved, safety was evaluated based on the incidence of various intraoperative and postoperative adverse events. Results: The success rates of intraoperative sedation were 82% in group R1, 98% in group R2, 96% in group R3, and 100% in group P. The incidence of hypotension was lower in the remimazolam groups than in the propofol group (16%), 4% in group R1, 6% in group R2, and 6% in group R3. The incidence of postoperative vertigo was significantly higher, and sedation recovery time was prolonged in high-concentration remimazolam group. Conclusion: Satisfactory efficacy can be obtained with higher concentrations of remimazolam tosilate in patients undergoing upper gastrointestinal endoscopy with ASA grade I or II. However, as the dose is progressively increased, the incidence of adverse reactions by remimazolam tosilate are also significantly increased, such as vertigo and prolonged sedation recovery time. Trial Registration: The trial was registered prior to enrollment at the Chinese Clinical Trial Registry (ChiCTR 2000032067).

Non-invasive model for predicting high-risk esophageal varices based on liver and spleen stiffness.

BACKGROUND: Acute bleeding due to esophageal varices (EVs) is a life-threatening complication in patients with cirrhosis. The diagnosis of EVs is mainly through upper gastrointestinal endoscopy, but the discomfort, contraindications and complications of gastrointestinal endoscopic screening reduce patient compliance. According to the bleeding risk of EVs, the Baveno VI consensus divides varices into high bleeding risk EVs (HEVs) and low bleeding risk EVs (LEVs). We sought to identify a non-invasive prediction model based on spleen stiffness measurement (SSM) and liver stiffness measurement (LSM) as an alternative to EVs screening. AIM: To develop a safe, simple and non-invasive model to predict HEVs in patients with viral cirrhosis and identify patients who can be exempted from upper gastrointestinal endoscopy. METHODS: Data from 200 patients with viral cirrhosis were included in this study, with 140 patients as the modelling group and 60 patients as the external validation group, and the EVs types of patients were determined by upper gastrointestinal endoscopy and the Baveno VI consensus. Those patients were divided into the HEVs group (66 patients) and the LEVs group (74 patients). The effect of each parameter on HEVs was analyzed by univariate and multivariate analyses, and a non-invasive prediction model was established. Finally, the discrimination ability, calibration ability and clinical efficacy of the new model were verified in the modelling group and the external validation group. RESULTS: Univariate and multivariate analyses showed that SSM and LSM were associated with the occurrence of HEVs in patients with viral cirrhosis. On this basis, logistic regression analysis was used to construct a prediction model: Ln [P/(1-P)] = -8.184 -0.228 × SSM + 0.642 × LSM. The area under the curve of the new model was 0.965. When the cut-off value was 0.27, the sensitivity, specificity, positive predictive value and negative predictive value of the model for predicting HEVs were 100.00%, 82.43%, 83.52%, and 100%, respectively. Compared with the four prediction models of liver stiffness-spleen diameter to platelet ratio score, variceal risk index, aspartate aminotransferase to alanine aminotransferase ratio, and Baveno VI, the established model can better predict HEVs in patients with viral cirrhosis. CONCLUSION: Based on the SSM and LSM measured by transient elastography, we established a non-invasive prediction model for HEVs. The new model is reliable in predicting HEVs and can be used as an alternative to routine upper gastrointestinal endoscopy screening, which is helpful for clinical decision making.

Efficacy and safety comparison of esketamine-propofol with nalbuphine-propofol for upper gastrointestinal endoscopy in children: a multi-center randomized controlled trial.

Background and Aims: Anesthetics such as propofol, esketamine and nalbuphine are used during the upper gastrointestinal endoscopy to achieve and maintain the desired sedation level. The aim of the study was to evaluate the effectiveness and safety of propofol-nalbuphine and propofol-esketamine in children. Methods: A multi-centered study was performed at three tertiary class-A hospitals. Children between 3 and 12 years old undergoing diagnostic painless upper gastrointestinal endoscopy were included and randomly divided into esketamine or nalbuphine group to estimate the primary outcome of successful endoscope insertion. The patients were given esketamine 0.5 mg/kg and propofol 2 mg/kg intravenously in esketamine group, with nalbuphine 0.2 mg/kg and propofol 2 mg/kg in the nalbuphine group. The primary outcome was success rate for the first attempt of endoscope insertion in each group. Secondary outcomes included the safety of both anesthesia regimens and gastroenterologist's satisfaction. We used the Face, Leg, Activity, Cry and Consolability (FLACC) scale to evaluate the level of pain before and during the procedure and the Pediatric Anesthesia Emergence Delirium (PAED) scale to assess the level of agitation and delirium after awakening from anesthesia. Results: Among 246 patients, 200 were randomly included in the final intention-to-treat analysis, with 100 patients in each group. The success rate for the first attempt of endoscope insertion in the esketamine group was higher than the nalbuphine group (97% vs. 66%; P < 0.01). The heart rate and mean arterial pressure after intraoperative administration in the esketamine group were higher than those in the nalbuphine group, while the delirium incidence during awakening was higher in esketamine group (all P < 0.05). Conclusion: The success rate for the first attempt of endoscope insertion of children undergoing upper gastrointestinal endoscopy in the esketamine group was higher than the nalbuphine group, propofol-related hemodynamic changes were reduced accordingly, while the incidence of esketamine-related adverse effects could be high.
