A clinical study on the relationship between chronic rhinosinusitis and bronchial asthma.

To investigate the correlation between chronic rhinosinusitis (CRS) and bronchial asthma, focusing on the CRS without nasal polyps (CRSsNP) and CRS with nasal polyps (CRSwNP), as well as their impact on lung function. A total of 141 patients diagnosed with chronic nasal-sinus inflammation were included in this study. Clinical data, including medical histories, nasal endoscopy scores, CT scores, symptom scores, and quality of life assessments, were collected. Among the patients with CRSsNP, 23.8% had concomitant bronchial asthma. The incidence of asthma was significantly associated with the severity of sinus involvement in CRSsNP patients (p = 0.049). Pulmonary function impairment was correlated with the severity of sinus inflammation in CRSsNP patients (p = 0.019). Quality of life was significantly affected in patients with concomitant asthma and CRSsNP or CRSwNP. Chronic rhinosinusitis, both with and without nasal polyps, is closely correlated with bronchial asthma. Pulmonary function impairment is associated with the extent of inflammatory lesions in CRSsNP. Although CRSwNP does not significantly affect pulmonary function, the treatment of sinus diseases can contribute to the control of asthma.

Positioning exercises in improving the quality of magnetic-controlled capsule endoscopy

BackgroundGood gastric preparation is indispensable for Magnetic-controlled Capsule Endoscopy (MCE) examination, but there is no consensus yet. We aim to explore the clinical application value of positioning exercises in improving the quality of MCE examination.MethodsClinical data of 326 patients who underwent MCE examination from January 2020 to December 2023 were collected. The included patients were divided into two groups: the conventional medication preparation group (CMP group, accepted mucosal cleansing medication only) and the positioning exercises group (PE group, accepted mucosal cleansing medication plus positioning exercises). A comparison was made between the two groups in terms of gastric cavity cleanliness score, visibility score, and detection rate of positive lesions.ResultsThe examination time was (21.29 ± 5.82) minutes in the PE group and (30.54 ± 6.37) minutes in the CMP group, showing a significant difference between the two groups (P < 0.001). The total cleanliness score and visibility score in the CMP group were 15.89 ± 2.82 and 10.93 ± 2.12, respectively. In contrast, the total cleanliness score and visibility score in the PE group were 19.52 ± 2.26 and 15.09 ± 2.31, respectively. The PE group showed significantly better cleanliness scores and visibility scores in all six anatomical regions compared to the CMP group (All P < 0.001). However, there was no significant difference in the detection rate of positive lesions between the two groups (All P > 0.05).ConclusionPositioning exercises before MCE examination can improve the quality of gastric mucosal images and reduce the duration of the examination for patients.

Painless colonoscopy: fact or fiction?

Although colonoscopy is a routinely performed procedure, it is not devoid of challenges, such as the potential for perforation and considerable patient discomfort, leading to patients postponing the procedure with several healthcare risks. This review delves into preprocedural and procedural solutions, and emerging technologies aimed at addressing the drawbacks of colonoscopies. Insufflation and sedation techniques, together with various other methods, have been explored to increase patient satisfaction, and thereby, the quality of endoscopy. Recent advances in this field include the prevention of loop formation, encompassing the use of variable-stiffness endoscopes, computer-guided scopes, magnetic endoscopic imaging, robotics, and capsule endoscopy. An autonomous endoscope that relies on self-propulsion to completely avoid looping is a potentially groundbreaking technology for the next generation of endoscopes. Nevertheless, critical techniques need to be refined to ensure the development of effective and efficient endoscopes.

The variation in post-endoscopy upper gastrointestinal cancer rates among endoscopy providers in England and associated factors: a population-based study.

Post-endoscopy upper gastrointestinal cancer (PEUGIC) is an important key performance indicator for endoscopy quality. We examined variation in PEUGIC rates among endoscopy providers in England and explored associated factors. The was a population-based, retrospective, case-control study, examining data from National Cancer Registration and Analysis Service and Hospital Episode Statistics databases for esophageal and gastric cancers diagnosed between 2009 and 2018 in England. PEUGIC were cancers diagnosed 6 to 36 months after an endoscopy that did not diagnose cancer. Associated factors were identified using multivariable logistic regression analyses. The national PEUGIC rate was 8.5%, varying from 5% to 13% among endoscopy providers. Factors associated with PEUGIC included: female sex (odds ratio [OR] 1.29 [95%CI 1.23-1.36]); younger age (age >80 years, OR 0.52 [0.48-0.56], compared with ≤60 years); increasing comorbidity (Charlson score >4, OR 5.06 [4.45-5.76]); history of esophageal ulcer (OR 3.30 [3.11-3.50]), Barrett's esophagus (OR 3.21 [3.02-3.42]), esophageal stricture (OR 1.28 [1.20-1.37]), or gastric ulcer (OR 1.55 [1.44-1.66]); squamous cell carcinoma (OR 1.50 [1.39-1.61]); and UK national endoscopy accreditation status - providers requiring improvement (OR 1.10 [1.01-1.20]), providers never assessed (OR 1.24 [1.04-1.47]). PEUGIC rates varied threefold among endoscopy providers, suggesting unwarranted differences in endoscopy quality. PEUGIC was associated with endoscopy findings known to be associated with upper gastrointestinal cancer and a lack of national endoscopy provider accreditation. PEUGIC variations suggest an opportunity to raise performance standards to detect upper gastrointestinal cancers earlier and improve outcomes.

Ability of detection in different resolution endoscopy for upper gastrointestinal mucosal lesions

BackgroundMost endoscopists believe that higher resolution improves lesion detection rates. However, existing studies primarily compared the detection rates of white light endoscopy (WLE) and other imaging modalities. Our previous study demonstrated the advantages of magnifying endoscopy from general endoscopy for lesion detection, prompting further investigation into the variations in lesion detection rates across endoscopes with different resolutions.MethodsEndoscopic and corresponding pathological data from our medical unit over the past 5 years were analyzed. We excluded specific-purpose endoscopic procedures to ensure the natural randomization of the data. Baseline adjustment and risk factor analyses used multi-group propensity score matching and logistic regression.ResultsThe overall lesion detection rate was significantly higher with high-quality endoscopy (Q-endoscopy) compared to high-definition endoscopy (H-endoscopy) and high definition and quality endoscopy (HQ-endoscopy) (34.4% vs. 30.2% vs. 29.6%, P = 0.001). Similar results were observed for elevated lesions (25.7% vs. 21.0% vs. 22.9%, P = 0.001) and depressed lesions (6.6% vs. 6.2% vs. 3.6%, P < 0.001). HQ-endoscopy had a superior detection rate for superficial lesions compared to both H- and Q-endoscopies (3.0% vs. 2.8% vs. 1.8%, P = 0.041). However, there were no significant differences in neoplastic detection rate or missed neoplastic lesion rate among the three groups.ConclusionQ-endoscopy is superior in detecting non-superficial lesions, while HQ-endoscopy is better at detecting superficial lesions. However, there were no statistically significant differences in detecting or omitting neoplastic lesions among the three endoscopic examinations.

Pediatric advanced complex endoscopy team enhances endoscopy quality and provider satisfaction.

Therapeutic endoscopic procedures are increasingly necessary for children. Pediatric gastroenterologist training and experience with endoscopic hemostasis and other complex therapeutic endoscopy procedures are often limited. We evaluated the impact of the implementation of an advanced complex endoscopy (ACE) team, which provides 24/7 inpatient/outpatient back-up endoscopy support. We analyzed hemostasis quality outcomes in the 2 years before implementation of ACE (2018-2020) versus the year following the implementation of ACE (2020-2021). We analyzed pediatric gastroenterology provider satisfaction and perspectives with a survey that was distributed to faculty, fellows, and advanced practice providers 1 month before implementation of ACE and again 12 months following ACE implementation. Endoscopy volume and outcome metrics for hemostasis procedures, including latency to endoscopy, need for reintervention, and administration/diversity of hemostatic therapy, including multimodal therapy, improved in the year following implementation of the ACE (p < 0.05 for each). Survey results demonstrated a positive impact on provider endoscopy experience and high utilization of ACE. Twenty-two percent of providers reported activating ACE in the prior month and 66% in the prior year. Most providers who activated ACE were very satisfied (85%) or satisfied (7.7%). Eighty-three percent noted ACE had a positive impact on inpatients, and 50% noted a positive impact on outpatient endoscopy. Provider anxiety with endoscopy diminished post-ACE implementation (62% vs. 28%). Respondents unanimously found ACE beneficial to patient care (100%). ACE implementation was associated with improved provider perspectives surrounding endoscopy and significant improvement in hemostasis quality parameters, escalation of hemostasis procedure volume, and broadening the range of hemostasis interventions.

Challenges in early detection and endoscopic resection of esophageal cancer: There is a long way to go.

The publication by Qu et al provided a comprehensive discussion about the epidemiology, etiology, histopathology, early detection, and endoscopic treatment of esophageal carcinoma (EC) and summarized the progress in the advanced technologies for screening and endoscopic resection for EC. In this editorial, we will provide deeper insight into the challenges that hinder practical application of these advanced technologies along with the role of these technologies in upper endoscopy quality. More efforts need to be made to overcome the challenges and add the value of these technologies in upper endoscopy quality. Clinical outcomes of management strategies after noncurative endoscopic dissection for early EC patients need further investigation. The experiences with noncurative endoscopic resection of other organs may have certain implications for noncurative resection of early EC.

Anesthesiologist-directed care for elective gastrointestinal endoscopy: results of an Italian multicentric prospective observational study.

Sedation, ranging from minimal, moderate and deep sedation to general anesthesia, improves patient comfort and procedure quality in gastrointestinal endoscopy (GIE). There are currently no comprehensive recommendations on sedation practice in diagnostic and therapeutic GIE. We aimed to investigate real-life sedation practice in elective GIE. We performed a multicentric observational study across 14 Endoscopy Units in Italy. We recorded consecutive data on all diagnostic procedures performed with Anesthesiologist-directed care (ADC) and all therapeutic procedures performed with ADC or non-Anesthesiologist sedation (NAS) over a three-month period. Dedicated ADC is available five days/week in 28.6% (4/14), four days/week in 21.5% (3/14), three days/week in 35.7% (5/14), two days/week in 7.1% (1/14) and one day/week in 7.1% (1/14) of participating Centers. ADC use for elective diagnostic GIE varied from 18.2% to 75.1% of the total number of procedures performed with ADC among different Centers. ADC use for elective therapeutic GIE varied from 10.8% to 98.9% of the total number of elective therapeutic procedures performed among different Centers. Our study highlights the lack of standardization and consequent great variability in sedation practice for elective GIE, with ADC being potentially overused for diagnostic procedures and underused for complex therapeutic procedures. A collaborative effort involving Endoscopists, Anesthesiologist and Institutions is needed to optimize sedation practice in GIE.

Mobile health technology in pediatric EGD quality indicators assessment: results from a national program of the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition

Background and aimsUpper endoscopy procedures (UEP, esophagogastroduodenoscopy [EGDS] and retrograde endoscopic retrograde cholangiography [ERCP]) are an established standard of care in pediatric gastroenterology. The Pediatric endoscopy quality improvement network (PEnQuIN) recently published its pediatric-specific endoscopy quality guidelines. This study, initiated by the Italian Society of Pediatric Gastroenterology, Hepatology and Nutrition (SIGENP), aims to evaluate the adherence of Italian Pediatric Endoscopy Centers to these established quality standards. MethodsConducted between April 2019 and March 2021, this nationwide study utilized a smartphone app-based approach. Data encompassing pediatric endoscopy facilities, patient profiles, endoscopy indications, 17 procedure-related PEnQuIN indicators, and a GHAA-9m patient satisfaction questionnaire were systematically collected. ResultsA comprehensive analysis of 3582 procedures from 24 PECs revealed that 2654 (76%) were UEP. The majority of centers (75%) involved more than one operator, with 9 PEC incorporating adult endoscopists, responsible for 5% of UEPs. Overall, adherence to quality standards was good; however, areas of improvement include sub-optimal reporting of sedation details, adherence to disease-specific guidelines, and patient satisfaction questionnaire completeness (56%). The complication rate aligned with literature standards (1%), and patient satisfaction was generally high. A noteworthy observation was a 30% decrease monthly reporting rate and a shift in disease-specific patterns following the COVID-19 outbreak. ConclusionsPediatric UEP practices in Italy adhere well to established quality standards. Emphasizing the adoption of disease-specific guidelines is crucial for optimizing resources, enhancing diagnostic accuracy, and minimizing unnecessary procedures. Prioritizing patient satisfaction is important for immediate enhancements in practice as well as for future research endeavors.

AI and endoscopy/histology in UC: the rise of machine.

The gap between endoscopy and histology is getting closer with the introduction of sophisticated endoscopic technologies. Furthermore, unprecedented advances in artificial intelligence (AI) have enabled objective assessment of endoscopy and digital pathology, providing accurate, consistent, and reproducible evaluations of endoscopic appearance and histologic activity. These advancements result in improved disease management by predicting treatment response and long-term outcomes. AI will also support endoscopy in raising the standard of clinical trial study design by facilitating patient recruitment and improving the validity of endoscopic readings and endoscopy quality, thus overcoming the subjective variability in scoring. Accordingly, AI will be an ideal adjunct tool for enhancing, complementing, and improving our understanding of ulcerative colitis course. This review explores promising AI applications enabled by endoscopy and histology techniques. We further discuss future directions, envisioning a bright future where AI technology extends the frontiers beyond human limits and boundaries.

Current Pediatric Endoscopy Training Situation in the Asia-Pacific Region: A Collaborative Survey by the Asian Pan-Pacific Society for Pediatric Gastroenterology, Hepatology and Nutrition Endoscopy Scientific Subcommittee.

To date, there is no region-specific guideline for pediatric endoscopy training. This study aimed to illustrate the current status of pediatric endoscopy training in Asia-Pacific region and identify opportunities for improvement. A cross-sectional survey, using a standardized electronic questionnaire, was conducted among medical schools in the Asia-Pacific region in January 2024. A total of 57 medical centers in 12 countries offering formal Pediatric Gastroenterology training programs participated in this regional survey. More than 75% of the centers had an average case load of <10 cases per week for both diagnostic and therapeutic endoscopies. Only 36% of the study programs employed competency-based outcomes for program development, whereas nearly half (48%) used volume-based curricula. Foreign body retrieval, polypectomy, percutaneous endoscopic gastrostomy, and esophageal variceal hemostasis, that is, sclerotherapy or band ligation (endoscopic variceal sclerotherapy and endoscopic variceal ligation), comprised the top four priorities that the trainees should acquire in the autonomous stage (unconscious) of competence. Regarding the learning environment, only 31.5% provided formal hands-on workshops/simulation training. The direct observation of procedural skills was the most commonly used assessment method. The application of a quality assurance (QA) system in both educational and patient care (Pediatric Endoscopy Quality Improvement Network) aspects was present in only 28% and 17% of the centers, respectively. Compared with Western academic societies, the limited availability of cases remains a major concern. To close this gap, simulation and adult endoscopy training are essential. The implementation of reliable and valid assessment tools and QA systems can lead to significant development in future programs.

Enhancing the Quality of Upper Gastrointestinal Endoscopy: Current Indicators and Future Trends

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

Upper Gastrointestinal Endoscopy Quality in Italy: A Nationwide Study.

International guidelines advise improving esophagogastroduodenoscopy (EGD) quality in Western countries, where gastric cancer is still diagnosed in advanced stages. This nationwide study investigated some indicators for the quality of EGD performed in endoscopic centers in Italy. Clinical, endoscopic, and procedural data of consecutive EGDs performed in one month in the participating centers were reviewed and collected in a specific database. Some quality indicators before and during endoscopic procedures were evaluated. A total of 3,219 EGDs performed by 172 endoscopists in 28 centers were reviewed. Data found that some relevant information (family history for GI cancer, smoking habit, use of proton pump inhibitors) were not collected before endoscopy in 58.5-80.7% of patients. Pre-endoscopic preparation for gastric cleaning was routinely performed in only 2 (7.1%) centers. Regarding the procedure, sedation was not performed in 17.6% of patients, and virtual chromoendoscopy was frequently (>75%) used in only one (3.6%) center. An adequate sampling of the gastric mucosa (i.e., antral and gastric body specimens) was heterogeneously performed, and it was routinely performed only by 23% of endoscopists, and in 14.3% centers. Our analysis showed that the quality of EGD performed in clinical practice in Italy deserves to be urgently improved in different aspects.

Interim Analysis of a Trial Evaluating the Utility of Non-Targeted Biopsies for Colorectal Neoplasia Detection in Inflammatory Bowel Disease

Persons with inflammatory bowel disease (IBD) affecting the colorectum (cIBD) have a 1.5- to 2-fold higher risk of developing colorectal cancer (CRC) relative to age- and sex-matched members of the general population.1 Intensive surveillance colonoscopy is recommended in this population to detect and treat early neoplastic lesions before they evolve to incurable cancers.2 Some societies advocate for widespread non-targeted ("random") biopsies throughout the colorectum to screen for "invisible" neoplastic lesions, in addition to targeted biopsies and/or resection of visible lesions.2 Despite the theoretical value of non-targeted biopsies in this setting, there are no high-quality, controlled data to support this practice. In addition to adding significant time and costs to colonoscopy screening, extensive biopsy sampling may also increase the risk of colorectal bleeding and bowel perforation, particularly in elderly patients and those receiving anticoagulant/antiplatelet therapies. With the widespread adoption of disease-modifying biologic and small molecule therapies,3 mucosal healing as a treatment end point,4 high-definition endoscopes,5 and endoscopy quality standards,6 as well as reports of very low neoplasia yield for non-targeted biopsies (0.1%-0.2% of biopsies),7 many experts have started to question the value of non-targeted biopsies as an adjunct for neoplasia surveillance in persons with cIBD.8 However, a recent large French cohort study reported that non-targeted biopsies still identify up to 20% of all neoplastic foci in persons with cIBD,9 albeit primarily in individuals with other major CRC risk factors.

Promoting Research that Supports High-Quality Gastrointestinal Endoscopy in Children.

Defining and measuring the quality of endoscopic care is a key component of performing gastrointestinal endoscopy in children. The purpose of this review is to discuss quality metrics for pediatric gastrointestinal endoscopy and identify where additional research is needed. Pediatric-specific standards and indicators were recently defined by the international Pediatric Endoscopy Quality Improvement Network (PEnQuIN) working group through a rigorous guideline consensus process. Although the aim of these guidelines is to facilitate best practices for safe and high-quality gastrointestinal endoscopy in children, they highlight the pressing need to expand upon the body of evidence supporting these standards and indicators as predictors of clinically relevant outcomes. In this review, we propose and discuss ideas for several high-yield research topics to engage pediatric endoscopists and promote best practices in pediatric endoscopy.

Current status of quality control in screening esophagogastroduodenoscopy and the emerging role of artificial intelligence.

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

Image Quality and Related Outcomes of the ShuntScope-Guided Catheter Implantation in Adult Hydrocephalus: Experience of 63 Procedures.

Ventricular catheter (VC) placement in the selected subset of adult hydrocephalus can be highly challenging due to abnormal anatomical configuration or the need for trans-aqueductal stent placement. Transluminal endoscopy with the ShuntScope has been invented to increase the success rate of catheter placement. This study evaluates the image qualities of ShuntScope and related surgical outcomes in adults. A retrospective analysis of all adult patients undergoing VC placement using the ShuntScope from November 2011 to July 2022 in the authors' department was performed. Demographic, clinical, and radiologic data were evaluated. The visualization quality of the intraoperative endoscopy was stratified into excellent, medium, and poor, and compared to the postoperative catheter tip placement. Follow-up evaluation included the surgical revision rate due to proximal catheter misplacement. A total of 63 ShuntScope-assisted surgeries have been performed on 60 adults. The mean age of the patients was 48.43 years. The most common underlying pathology was a tumor- or cyst-related cerebrospinal fluid (CSF) impairment in 38.33%, followed by a pseudotumor cerebri in 21.66%. The achieved image quality was excellent in 39.68%, medium in 47.62%, and poor in 12.7%. Ideal catheter placement was achieved in 79.37%. There were no intraoperative complications associated with the use of the ShuntScope. The revision rate due to suboptimal proximal VC placement was 4.76% during a mean follow-up period of 27.75 months. A statistical correlation between the image quality and accuracy of the catheter position was observed (p < 0.001). The ShuntScope can be considered an important addition to standard surgical tools in treating a selected subset of adult hydrocephalus. Direct visualization might even help achieve correct placement of the catheter in the cases with blurred vision and limited visual overview.

Endoscopic features of low-grade dysplastic Barrett's.

Background and study aims Barrett's esophagus (BE) with low-grade dysplasia (LGD) is considered usually endoscopically invisible and the endoscopic features are not well described. This study aimed to: 1) evaluate the frequency of visible BE-LGD; 2) compare rates of BE-LGD detection in the community versus a Barrett's referral unit (BRU); and 3) evaluate the endoscopic features of BE-LGD. Patients and methods This was a retrospective analysis of a prospectively observed cohort of 497 patients referred to a BRU with dysplastic BE between 2008 and 2022. BE-LGD was defined as confirmation of LGD by expert gastrointestinal pathologist(s). Endoscopy reports, images and histology reports were reviewed to evaluate the frequency of endoscopically identifiable BE-LGD and their endoscopic features. Results A total of 135 patients (27.2%) had confirmed BE-LGD, of whom 15 (11.1%) had visible LGD identified in the community. After BRU assessment, visible LGD was detected in 68 patients (50.4%). Three phenotypes were observed: (A) Non-visible LGD; (B) Elevated (Paris 0-IIa) lesions; and (C) Flat (Paris 0-IIb) lesions with abnormal mucosal and/or vascular patterns with clear demarcation from regular flat BE. The majority (64.7%) of visible LGD was flat lesions with abnormal mucosal and vascular patterns. Endoscopic detection of BE-LGD increased over time (38.7% (2009-2012) vs. 54.3% (2018-2022)). Conclusions In this cohort, 50.4% of true BE-LGD was endoscopically visible, with increased recognition endoscopically over time and a higher rate of visible LGD detected at a BRU when compared with the community. BRU assessment of BE-LGD remains crucial; however, improving endoscopy surveillance quality in the community is equally important.
