Influences of Propofol, Ciprofol and Remimazolam on Dreaming During Anesthesia for Gastrointestinal Endoscopy: A Randomized Double-Blind Parallel-Design Trial.

Purpose: To compare the influences of propofol, ciprofol and remimazolam on dreaming during painless gastrointestinal endoscopy. Methods: This study was a single-center, prospective, parallel-design, double-blind, randomized clinical trial. Between May 2023 and October 2023, patients undergoing elective painless gastrointestinal endoscopy were recruited and randomly allocated into one of the three groups. Demographic data, intraoperative information, incidence of dreaming, insufficient anesthesia and intraoperative awareness, type of dream, patient satisfaction score, adverse events, and improvement of sleep quality were collected. Results: The difference in incidence of dreaming among the three groups was not significant (33.33% vs 48.33% vs 41.67%, p=0.061). The number of patients with intraoperative hypotension in the propofol group was larger than that of the remimazolam group (32 vs 12, p=0.001). However, the cases of intraoperative hypotension between propofol group and ciprofol group or ciprofol group and remimazolam group were comparable (32 vs 22, p=0.122; 22 vs 12, p=0.064). The percentage of insufficient anesthesia between propofol group and remimazolam group was significant (13.33% vs 1.67%, p=0.001), while no statistical difference was detected between propofol group and remimazolam group or ciprofol group and remimazolam group (13.33% vs 5.00%, p=0.025; 5.00% vs 1.67%, p=0.150). The ability of propofol to improve sleep quality at 1st post-examination day was significantly better than that of remimazolam (86.21% vs 72.88%, p=0.015), while it was not significant between propofol group and ciprofol group or ciprofol group and remimazolam group (86.21% vs 80.36%, p=0.236; 72.88% vs. 72.88%, p=0.181). Incidence of intraoperative awareness, intraoperative hypoxia, type of dream, satisfaction score, adverse events during recovery, and sleep improvement on the 7th post-examination day was not significant among the groups. Conclusion: Anesthesia with propofol, ciprofol and remimazolam, respectively, for gastrointestinal endoscopy did not induce statistical difference in the incidence of dreaming, despite that all of them are more likely to induce pleasant dreams.

Esofagitis disecante supeEsofagitis disecante superficial: dos casos de una misma entidad poco frecuente / Esophagitis dissecans superficialis: two cases of the same rare entity

La esofagitis disecante superficial (EDS) es una entidad infrecuente que se caracteriza endoscópicamente por el desprendimiento de las capas superficiales del epitelio esofágico e, histológicamente, por el aspecto bitonal del epitelio escamoso esofágico secundario a la necrosis de los estratos más superficiales. La etiología es desconocida, aunque se ha asociado con la ingesta de determinados fármacos, enfermedades autoinmunes, estasis esofágica y procedimientos endoscópicos. Presentamos dos casos: uno de ellos acontece en una mujer tras un episodio de disfagia abrupta y el segundo en un varón con comorbilidades y clínica de dolor epigástrico. La EDS es una patología que hay que considerar en su adecuado contexto clínico y endoscópico, ya que su curso es autolimitado en comparación con otras entidades de evolución tórpida o que precisan un tratamiento específico. (AU)

Esophagitis dissecans superficialis (EDS) is a rare disease characterized by sloughing of the superficial esophageal mucosa and, histologically, by the bitonal appearance of the squamous epithelium secondary to necrosis of the most superficial layers. Etiology is uncertain, however, it has been associated with some medications, autoimmune diseases, esophageal stasis and endoscopic procedures. Here, two cases are presented, one of them which appeared in a woman after an episode of dysphagia and another one which occurred to a man with comorbidities and epigastric pain. This entity should be considered due to its self-limiting clinical course, compared to other entities with a more torpid evolution or that require more specific treatment. (AU)

Endoscopic management of surgical complications.

While the endoscopic management of surgical complications like leaks, fistulas, and perforations is rapidly evolving, its core principles revolve around closure, drainage, and containment. Effectively managing these conditions relies on several factors, such as the underlying cause, chronicity of the lesion, tissue viability, co-morbidities, availability of devices, and expertise required to perform the endoscopy. In contrast to acute perforation, fistulas and leaks often demand a multimodal approach requiring more than one session to achieve the required results. Although the ultimate goal is complete resolution, these endoscopic interventions can provide clinical stability, enabling enteral feeding to lead to early hospital discharge or elective surgery. In this discussion, we emphasize the current state of knowledge and the prospective role of endoscopic interventions in managing surgical complications.

Endoscopic management of intraprocedural bleeding during endoscopic interventions.

Endoscopic resection techniques have evolved over time, allowing effective and safe resection of the majority of pre-malignant and early cancerous lesions in the gastrointestinal tract. Bleeding is one of the most commonly encountered complications during endoscopic resection, which can interfere with the procedure and result in serious adverse events. Intraprocedural bleeding is relatively common during endoscopic resection and, in most cases, is a mild and self-limiting event. However, it can interfere with the completion of the resection and may result in negative patient-related outcomes in severe cases, including the need for hospitalization and blood transfusion as well as the requirement for radiological or surgical interventions. Appropriate management of intraprocedural bleeding can improve the safety and efficacy of endoscopic resection, and it can be readily achieved with the use of several endoscopic hemostatic tools. In this review, we discuss the recent advances in the approach to intraprocedural bleeding complicating endoscopic resection, with a focus on the various endoscopic hemostatic tools available to manage such events safely and effectively.

Value of integrated pulmonary index monitoring for the detection of adverse respiratory events in patients undergoing sedation for gastrointestinal system endoscopy.

Objectives: To determine if the integrated pulmonary index detects changes in ventilation status early in patients undergoing gastrointestinal endoscopy under sedation, and to determine the risk factors affecting hypoxia. METHODS: The retrospective study was conducted at the endoscopy unit of a tertiary university hospital in Turkey and comprised data between October 2018 and December 2019 related to patients of either gender aged >18 years who were assessed as American Society of Anaesthesiologists grade I-III and underwent elective lower and upper gastrointestinal endoscopy. Monitoring was done with capnography in addition to standard procedures. Data was analysed using SPSS 23. RESULTS: Of the 154 patients, 94(%) were females and 60(%) were males. The overall mean age was 50.88±11.8 years (range: 20-70 years). Mean time under anaesthesia was 23.58±4.91 minutes and mean endoscopy time was 21.73±5.06 minutes. During the procedure, hypoxia was observed in 42(27.3%) patients, severe hypoxia in 23(14.9%) and apnoea in 70(45.5%). Mean time between apnoea and hypoxia was 12.59±7.99 seconds, between apnoea and serious hypoxia 21.07±17.64 seconds, between integrated pulmonary index score 1 and hypoxia 12.91±8.17 sec, between integrated pulmonary index score 1 and serious hypoxia 21.59±14.13 seconds, between integrated pulmonary index score <7 and hypoxia 19.63±8.89 seconds, between integrated pulmonary index score <7 and serious hypoxia 28.39±12.66 seconds, between end-tidal carbon dioxide and hypoxia 12.95±8.33 seconds, and between end-tidal carbon dioxide and serious hypoxia 21.29±7.55 seconds. With integrated pulmonary index score 1, sensitivity value for predicting hypoxia and severe hypoxia was 88.1% and 95.7%, respectively, and specificity was 67% and 60.3%, respectively. With integrated pulmonary index score <7, the corresponding values were 100%, 100%, 42% and 64.1%, respectively. CONCLUSIONS: Capnographic monitoring, especially the follow-up integrated pulmonary index score, was found to be valuable and reliable in terms of finding both time and accuracy of the risk factor in the diagnosis of respiratory events.

[Reduction in Helicobacter pylori infection among patients referred for upper gastrointestinal endoscopy in Santiago, Chile, between 2010-2020]. / Reducción de la infección por Helicobacter pylori en pacientes derivados a endoscopia digestiva alta en Santiago de Chile entre 2010-2020.

Latin America presents a high prevalence of Helicobacter pylori(Hp) infection. Between1996-2003, the prevalence in Santiago, Chile, was 70%; recent studies indicate a decreasein this infection. Updating the frequency of Hp is crucial due to its associated health impact. OBJECTIVE: Our objective was to describe the trend in Hp infection in patients undergoingambulatory esophagogastroduodenoscopy (EGD) in a Chilean population. MATERIALS AND METHODS: A retrospective observational study was conducted on patients over 18 years old who attended a first EGD with a rapid urease test between 2010-2020. Time trendswere described through time series analysis. A Poisson model was constructed to estimatethe risk of infection, adjusted for age and gender. RESULTS: 11,355 patients were included[66.9% females; mean age 52 years; Hp 41.6%]. Male gender presented a higher frequencyof Hp infection [RR 1.13; (95% CI: 1.08-1.18)].Hp frequency infection decreased significantlyfrom 45.1% in 2010 to 29% in 2020, with a 36% lower probability of Hp infection in 2020 compared to 2010 [RR 0.64;(95% CI: 0.55-0.74)]. A progressive decline in Hp infectiontrend was projected, reaching values close to 25% by year 2025. CONCLUSION: A significantreduction in Hpinfection was observed between 2010-2020. This decrease could be explained by the implementation of public health policies in the last decade associated with socio-sanitary changes.

Endoscopic treatment of gastroesophageal reflux disease.

The endoscopic treatment of gastroesophageal reflux disease (GERD) has evolved significantly in the past 20 years. Current practices include devices specifically designed for GERD. Newer techniques aim to use less extra equipment, to be less costly, and to use accessories readily available in endoscopy units, as well as using standard endoscopes to apply such techniques. It is of utmost importance to properly select the patients for endoscopic therapy, and it should be done in a multidisciplinary approach.

El tratamiento endoscópico de la enfermedad por reflujo gastroesofágico (ERGE) ha evolucionado significativamente en los últimos 20 años. Las prácticas actuales incluyen dispositivos diseñados específicamente para la ERGE. Las técnicas más nuevas tienen como objetivo utilizar menos equipos adicionales, ser menos costosos y utilizar accesorios fácilmente disponibles en las unidades de endoscopia, así como utilizar endoscopios estándar para aplicar dichas técnicas. Es de suma importancia seleccionar adecuadamente a los pacientes para la terapia endoscópica, y debe hacerse en un enfoque multidisciplinario.

Helicobacter pylori infection found during upper endoscopy performed for the diagnosis of celiac, inflammatory bowel diseases, and eosinophilic esophagitis: A multicenter pediatric European study.

BACKGROUND: Helicobacter pylori may be found during upper gastrointestinal endoscopy (UGE) performed to diagnose celiac disease (CeD), inflammatory bowel disease (IBD), and eosinophilic esophagitis (EoE). We aimed to describe the frequency of H. pylori in children undergoing UGE for CeD, IBD, and EoE and the number of children receiving eradication treatment. MATERIALS AND METHODS: A retrospective multicenter study from 14 countries included pediatric patients diagnosed with CeD, IBD, and EoE between January 2019 and December 2021. DATA COLLECTED: age, gender, hematologic parameters, endoscopic, histologic, and H. pylori culture results, and information on eradication treatment. RESULTS: H. pylori was identified in 349/3890 (9%) children [167 (48%) male, median 12 years (interquartile range 8.1-14.6)]. H. pylori was present in 10% (173/1733) CeD, 8.5% (110/1292) IBD and 7.6% (66/865) EoE patients (p = NS). The prevalence differed significantly between Europe (Eastern 5.2% (28/536), Southern 3.8% (78/2032), Western 5.6% (28/513)) and the Middle East 26.6% (215/809) [odds ratio (OR) 7.96 95% confidence interval (CI) (6.31-10.1) p < 0.0001]. Eradication treatment was prescribed in 131/349 (37.5%) patients, 34.6% CeD, 35.8% IBD, and 56.1% EoE. Predictors for recommending treatment included erosions/ulcers [OR 6.45 95% CI 3.62-11.47, p < 0.0001] and nodular gastritis [OR 2.25 95% CI 1.33-3.81, p 0.003]. Treatment rates were higher in centers with a low H. pylori prevalence (<20%) [OR 3.36 95% CI 1.47-7.66 p 0.004]. CONCLUSIONS: Identifying H. pylori incidentally during UGE performed for the most common gastrointestinal diseases varies significantly among regions but not among diseases. The indications for recommending treatment are not well defined, and less than 40% of children received treatment.

The contribution of EUS to the management of endoscopic and surgical complications.

Endoscopic Ultrasound (EUS) stands as a remarkable innovation in the realm of gastroenterology and its allied disciplines. EUS has evolved to such an extent that it now assumes a pivotal role in both diagnosis and therapeutics. In addition, it has developed as a tool which is also capable of addressing complications arising from endoscopic and surgical procedures. This minimally invasive technique combines endoscopy with high-frequency ultrasound, facilitating, high-resolution images of the gastrointestinal tract and adjacent structures. Complications within the gastrointestinal tract, whether stemming from endoscopic or surgical procedures, frequently arise due to disruption in the integrity of the gastrointestinal tract wall. While these complications are usually promptly detected, there are instances where their onset is delayed. EUS plays a dual role in the management of these complications. Firstly, in its ability to assess and increasingly to definitively manage complications through drainage procedures. It is increasingly employed to manage post-surgical collections, abscesses biliary strictures and bleeding. Its high-resolution imaging capability allows precise real-time visualisation of these complications.

Polyp segmentation based on implicit edge-guided cross-layer fusion networks.

Polyps are abnormal tissue clumps growing primarily on the inner linings of the gastrointestinal tract. While such clumps are generally harmless, they can potentially evolve into pathological tumors, and thus require long-term observation and monitoring. Polyp segmentation in gastrointestinal endoscopy images is an important stage for polyp monitoring and subsequent treatment. However, this segmentation task faces multiple challenges: the low contrast of the polyp boundaries, the varied polyp appearance, and the co-occurrence of multiple polyps. So, in this paper, an implicit edge-guided cross-layer fusion network (IECFNet) is proposed for polyp segmentation. The codec pair is used to generate an initial saliency map, the implicit edge-enhanced context attention module aggregates the feature graph output from the encoding and decoding to generate the rough prediction, and the multi-scale feature reasoning module is used to generate final predictions. Polyp segmentation experiments have been conducted on five popular polyp image datasets (Kvasir, CVC-ClinicDB, ETIS, CVC-ColonDB, and CVC-300), and the experimental results show that the proposed method significantly outperforms a conventional method, especially with an accuracy margin of 7.9% on the ETIS dataset.

[Multiple ileal neuroendocrine tumors 10mm in diameter with lymph node metastasis detected on endoscopy:a case report].

A 53-year-old man with an abnormal routine physical examination was referred to our hospital. Colonoscopy showed a 5-mm submucosal tumor that was 7cm proximal to the ileocecal valve. It was identified as a neuroendocrine tumor (NET) on biopsy. Preoperatively, we conducted a double balloon endoscopy to examine the entire small intestine. Another 7-mm submucosal tumor was found on the ileocecal valve, which was missed during the first colonoscopy. A final diagnosis of multiple ileal NETs (<10mm in diameter) was made, and the patient underwent ileocecal resection with lymphadenectomy. Histopathological evaluation of the surgical specimen verified the diagnosis of NET Grade 1 with submucosal invasion. Metastasis to lymph node #202 was also detected. He remained relapse-free for 5 years and 5 months after the operation. In conclusion, this was a case of multiple ileal NETs (<10mm in diameter) with lymph node metastasis that could not be detected preoperatively on contrast-enhanced computed tomography. This case highlights the significance of detailed endoscopic observation of the terminal ileum.

Clinical manifestations, diagnosis and long-term prognosis of adult autoimmune enteropathy: Experience from Peking Union Medical College Hospital.

BACKGROUND: Autoimmune enteropathy (AIE) is a rare disease whose diagnosis and long-term prognosis remain challenging, especially for adult AIE patients. AIM: To improve overall understanding of this disease's diagnosis and prognosis. METHODS: We retrospectively analyzed the clinical, endoscopic and histopathological characteristics and prognoses of 16 adult AIE patients in our tertiary medical center between 2011 and 2023, whose diagnosis was based on the 2007 diagnostic criteria. RESULTS: Diarrhea in AIE patients was characterized by secretory diarrhea. The common endoscopic manifestations were edema, villous blunting and mucosal hyperemia in the duodenum and ileum. Villous blunting (100%), deep crypt lymphocytic infiltration (67%), apoptotic bodies (50%), and mild intraepithelial lymphocytosis (69%) were observed in the duodenal biopsies. Moreover, there were other remarkable abnormalities, including reduced or absent goblet cells (duodenum 94%, ileum 62%), reduced or absent Paneth cells (duodenum 94%, ileum 69%) and neutrophil infiltration (duodenum 100%, ileum 69%). Our patients also fulfilled the 2018 diagnostic criteria but did not match the 2022 diagnostic criteria due to undetectable anti-enterocyte antibodies. All patients received glucocorticoid therapy as the initial medication, of which 14/16 patients achieved a clinical response in 5 (IQR: 3-20) days. Immunosuppressants were administered to 9 patients with indications of steroid dependence (6/9), steroid refractory status (2/9), or intensified maintenance medication (1/9). During the median of 20.5 months of follow-up, 2 patients died from multiple organ failure, and 1 was diagnosed with non-Hodgkin's lymphoma. The cumulative relapse-free survival rates were 62.5%, 55.6% and 37.0% at 6 months, 12 months and 48 months, respectively. CONCLUSION: Certain histopathological findings, including a decrease or disappearance of goblet and Paneth cells in intestinal biopsies, might be potential diagnostic criteria for adult AIE. The long-term prognosis is still unsatisfactory despite corticosteroid and immunosuppressant medications, which highlights the need for early diagnosis and novel medications.

Outpatient management of obscure gastrointestinal bleeding: A new perspective in high-risk patients.

Mid-gastrointestinal bleeding accounts for approximately 5%-10% of all gastrointestinal bleeding cases, and vascular lesions represent the most frequent cause. The rebleeding rate for these lesions is quite high (about 42%). We hereby recommend that scheduled outpatient management of these patients could reduce the risk of rebleeding episodes.

Examining the Frequency of Second Endoscopy and Its Effect on Patient Outcomes With Upper Gastrointestinal Bleeding in Southeast of Iran.

BACKGROUND: This study investigated the frequency and impact of repeat endoscopy in patients with acute upper gastrointestinal bleeding (AUGIB) in a referral hospital in Southeast Iran. MATERIALS AND METHODS: A cross-sectional descriptive-analytical study was conducted on the records of 190 patients who underwent endoscopy for AUGIB in 2019. The study compared the demographic and clinical characteristics, outcomes, and treatments of patients who had a second endoscopy (n=64) with those who did not (n=126). The data were analyzed with SPSS software, and a P value less than 0.05 was considered significant. RESULTS: The results showed that repeat endoscopy was not significantly associated with age, gender, initial symptoms, bleeding site, first endoscopy time, or disease outcome. However, repeat endoscopy was significantly associated with higher bleeding severity, different wound types, different bleeding causes, longer hospital stay, and different treatments in the first endoscopy. The main reasons for repeat endoscopy were poor visibility and recurrent bleeding. The majority of repeat endoscopies were performed within 2 days of the first one. Most patients who had a second endoscopy did not receive any treatment, and those who did received combined thermal and epinephrine injections. CONCLUSIONS: The study concluded that routine second endoscopy is not necessary for all patients with AUGIB, but it may be beneficial for some cases. Further research is needed to clarify the indications and timing of repeat endoscopy in AUGIB.

Disposable Gastrointestinal Scopes: A Systematic Review.

OBJECTIVE: Endoscopes are an essential tool in the diagnosis, screening, and treatment of gastrointestinal diseases. In 2019, the Food and Drug Administration issued a news release, recommending that duodenoscope manufacturers and health care facilities phase out fully reusable duodenoscopes with fixed endcaps in lieu of duodenoscopes that are either fully disposable or those that contain disposable endcaps. With this study, we systematically reviewed the published literature on single-use disposable gastrointestinal scopes to describe the current state of the literature and provide summary recommendations on the role of disposable gastrointestinal endoscopes. MATERIALS AND METHODS: For our inclusion criteria, we searched for studies that were published in the year 2015 and afterward. We performed a literature search in PubMed using the keywords, "disposable," "reusable," "choledochoscope," "colonoscope," "duodenoscope," "esophagoscope," "gastroscope," and "sigmoidoscope." After our review, we identified our final article set, including 13 articles relating to disposable scopes, published from 2015 to 2023. RESULTS: In this review, we show 13 articles discussing the infection rate, functionality, safety, and affordability of disposable gastrointestinal scopes in comparison to reusable gastrointestinal scopes. Of the 3 articles that discussed infection rates (by Forbes and colleagues, Ridtitid and colleagues, and Ofosu and colleagues), each demonstrated a decreased risk of infection in disposable gastrointestinal scopes. Functionality was another common theme among these articles. Six articles (by Muthusamy and colleagues, Bang and colleagues, Lisotti and colleagues, Ross and colleagues, Kang and colleagues, and Forbes and colleagues) demonstrated comparable functionality of disposable scopes to reusable scopes. The most reported functionality issue in disposable scopes was decreased camera resolution. Disposable scopes also showed comparable safety profiles compared with reusable scopes. Six articles (by Kalipershad and colleagues, Muthusamy and colleagues, Bang and colleagues, Lisotti and colleagues, Luo and colleagues, and Huynh and colleagues) showed comparable rates of AEs, whereas 1 article (by Ofosu and colleagues) demonstrated increased rates of AEs with disposable scopes. Lastly, a cost analysis was looked at in 3 of the articles. Two articles (by Larsen et al and Ross and colleagues) remarked that further research is needed to understand the cost of disposable scopes, whereas 1 article (by Kang and colleagues) showed a favorable cost analysis. CONCLUSIONS: After a review of the literature published since the 2015 Food and Drug Administration safety communication, disposable scopes have been shown to be effective in decreasing infection risks while maintaining similar safety profiles to conventional reusable scopes. However, more research is required to compare disposable and reusable scopes in terms of functionality and cost-effectiveness.
