Endoscopic submucosal dissection (ESD) is a reliable method to resect early esophageal cancer. Esophageal stricture is one of the major complications after ESD of the esophagus. Steroid prophylaxis for esophageal strictures, particularly local injection of triamcinolone acetonide (TA), is a relatively effective method to prevent esophageal strictures. However, even with steroid prophylaxis, stenosis still occurs in up to 45% of patients. Predicting the risk of stenosis formation after local TA injection would enable additional interventions in risky patients.

To identify the predictors of esophageal strictures after steroids application.

Patients who underwent esophageal ESD and steroid prophylaxis and who were comprehensively assessed for lesion- and ESD-related factors at Southeast University Affiliated Zhongda Hospital between February 2018 and March 2023 were included in the study. The univariate and multivariate regression analyses were conducted to identify the predictors of stricture among patients undergoing steroid prophylaxis.

A total of 120 patients were included in the analysis. In the oral prednisone and oral prednisone combined with local tretinoin injection groups, the stenosis rates were 44/53 (83.0%) and 56/67 (83.6%), respectively. Among them, univariate analysis showed that the lesion circumference (P = 0.01) and submucosal injection solution (P = 0.04) showed significant correlation with the risk of stenosis formation. Logistic regression analyses were then performed using predictors that were significant in the univariate analyses and combined with known predictors from previous reports, such as additional chemoradiotherapy and tumor location. We identified a lesion circumference < 5/6 (OR = 0.19; P = 0.02) and submucosal injection of sodium hyaluronate (OR = 0.15; P = 0.03) as independent predictors of on esophageal stricture formation.

Steroid prophylaxis effectively prevents stenosis. Moreover, the lesion circumference and submucosal injection of sodium hyaluronate were independent predictors of esophageal strictures. Additional interventions should be considered in high-risk patients.

Esophagopericardial fistula (EPF) is a rare, life-threatening condition with limited scientific literature and no established management guidelines. This case report highlights a successful multidisciplinary approach and the innovative use of endoscopic vacuum assisted closure (endoVAC) therapy in treating this complex condition.

A 16-year-old male with a history of esophageal atresia and colon interposition presented with progressive chest pain, fever, and dyspnea. Imaging revealed an EPF with associated pleural and pericardial effusions. Initial management with an esophageal stent failed, prompting the use of an endoVAC system. The patient underwent multiple endoVAC device changes and received broad-spectrum antibiotics and nutritional support. The fistula successfully closed, and the patient recovered, demonstrating no new symptoms at a 6-month follow-up.

EndoVAC therapy can effectively manage EPF, providing a minimally invasive treatment option.

Confocal laser endomicroscopy (CLE) is a novel endoscopic modality that provides real-time histological information via high-resolution magnified view of the mucosa. CLE has a higher sensitivity, specificity, and diagnostic accuracy in detecting atrophic gastritis as compared to chromoendoscopy and narrow-band imaging. It can even predict low-grade and high-grade intraepithelial neoplasia by analyzing gastric pit patterns. CLE may have some advantages over the standard biopsy protocol, such as higher diagnostic yield and fewer biopsy requirements. Its diagnostic accuracy in detecting superficial gastric cancer is higher than that of white-light endoscopy. Inherent limitations, such as a narrow field of vision, can be surpassed by technological advancements and integration with other detection methods. Artificial intelligence holds promise in automated analysis of histopathological images. Thus, CLE can be helpful in screening for early gastric cancer and may help reduce the risk of complications from repeated biopsies, such as mucosal damage, bleeding, and infection.

Helicobacter pylori (H. pylori) is the most common chronic bacterial infection in humans. The risk of acquiring H. pylori is related to socioeconomic status and living conditions early in life. Treatment regimens must consider local antibiotic resistance patterns. Adventist Health White Memorial Hospital serves a predominantly indigent population in east Los Angeles with a large number of immigrants from South and Central America. Data regarding the prevalence and resistance of H. pylori in this population is scant.

To evaluate the prevalence and resistance of H. pylori and correlate with country of origin.

All gastric biopsies were obtained by a single gastroenterologist at the hospital in a consecutive manner from patients with gastritis from 2017 to 2022 and sent to various labs for evaluation.

Two hundred and sixty-six patients are born in the United States, 450, 171, 70, and 30 patients are immigrants from Mexico, Central and South America (CSA), Asia, and other countries respectively. Overall, 14.65% were found to be infected with H. pylori. Rates of infection in United States-born citizens, immigrants from Mexico, CSA, and Asia are 9.02%, 18.67%, 13.45%, and 11.43% respectively, with Mexican immigrants having a relative risk of 2.3889 [95% confidence interval (CI): 1.4789-3.8588, P = 0.0004] compared to those born in United States. No correlation seen between infection and length of time immigrants were in United States. Relative risk of infection in patients with no proton pump inhibitor use within the past 30 days found to be 1.9276 (95%CI: 1.3562-2.7398, P = 0.0003). Rates of resistance for clarithromycin and levofloxacin are 21.43% and 31.11%.

H. pylori infection appears to be associated with low socioeconomic status and poor living conditions early in life. Clarithromycin and levofloxacin based treatment regimens should be avoided as first line therapy in this region, particularly in patients of Latin American origin.

Endoscopic retrograde cholangiopancreatography (ERCP) is associated with a variety of adverse events (AEs). One of the most important AEs is post-ERCP pancreatitis (PEP), which is most common in cases of difficult biliary cannulation. Although the precut technique has been reported as a PEP risk factor, recent studies indicate that early precut could reduce PEP, and that precut itself is not a risk factor.

To evaluate the safety of the precut technique, especially in terms of PEP.

We conducted a retrospective study, spanning the period from November 2011 through December 2021. It included 1556 patients, aged ≥ 20 years, who underwent their initial ERCP attempt for biliary disease with a naïve papilla at the Kawasaki University General Medical Center. We compared the PEP risk between the early precut and the delayed precut group.

The PEP incidence rate did not significantly differ between the precut and non-precut groups. However, the PEP incidence was significantly lower in the early precut group than the delayed precut group (3.5% vs 10.5%; P = 0.02). The PEP incidence in the delayed precut group without pancreatic stent insertion (17.3%) was significantly higher compared to other cases (P < 0.01).

Our findings indicate that early precut may reduce PEP incidence. If the precut decision is delayed, a pancreatic stent should be inserted to prevent PEP.

Approximately 7% of the polyps resected endoscopically have an adenocarcinoma focus, with no previous endoscopic evidence of malignancy. This raises the question of whether endoscopic resection has been curative. Furthermore, there is no consensus on what the endoscopic and histological criteria for good prognosis are, the appropriate follow-up strategy and what are the long-term results. The aim of the retrospective study by Fábián et al was to evaluate the occurrence of local relapse or distant metastasis in those tumors that were resected endoscopically compared to those that underwent oncologic surgery. They concluded that, regardless of the treatment strategy chosen, there was a higher recurrence rate than described in the literature and that adherence to follow-up was poor. The management approach for an endoscopically benign polyp histologically confirmed as adenocarcinoma depends on the presence of any of the previously described poor prognostic histological factors. If none of these factors are present and the polyp has been completely resected en bloc (R0), active surveillance is considered appropriate as endoscopic resection is deemed curative. These results highlight, once again, the need for further multicentric clinical practice studies to obtain more evidence for the purpose of establishing appropriate treatment and follow-up strategies.

Heterotopic mesenteric ossification (HMO) is a clinically rare condition characterized by the formation of bone tissue in the mesentery. The worldwide reporting of such cases is limited to just over 70 instances in the medical literature. The etiology of HMO remains unclear, but the disease is possibly induced by mechanical trauma, ischemia, or intra-left lower quadrant abdominal infection, leading to the differentiation of mesenchymal stem cells into osteoblasts. Here, we present a rare case of HMO that occurred in a 34-year-old male, who presented with left lower quadrant abdominal pain.

We report the case of a 34-year-old male patient who presented with left lower abdominal pain following trauma to the left lower abdomen. He subsequently underwent surgical treatment, and the postoperative pathological diagnosis was HMO.

We believe that although there is limited literature and research on HMO, when patients with a history of trauma or surgery to the left lower abdomen present with corresponding imaging findings, clinicians should be vigilant in distinguishing this condition and promptly selecting appropriate diagnostic and therapeutic interventions.

Interventional endoscopic ultrasound is clinically used for the treatment of isolated gastric varices (IGVs) owing to its precise visualization.

A 39-year-old man was diagnosed with a large IGV during a routine physical examination. Endoscopic ultrasonography showed gastric varices entwined with an artery, which greatly increased the difficulty of treatment. We successfully treated the patient with endoscopic ultrasonography-guided coil embolization combined with cyanoacrylate injection.

Endoscopic ultrasonography-guided coil embolization combined with cyanoacrylate injection was safe and effective for the treatment of an IGV entwined with an artery.

In this editorial, we explore the challenges of managing noncurative resections in early gastric cancer after endoscopic submucosal dissection (ESD), starting from the consideration recently made by Zhu et al. Specifically, we evaluate the management of eCura C1 lesions, where decisions regarding further interventions are pivotal yet contentious. Collaboration among endoscopists, surgeons, and pathologists is underscored to refine risk assessment and personalize therapeutic management. Recent advancements in ESD techniques and interdisciplinary collaboration offer opportunities for outcome optimization in managing eCura C1 lesions. Moreover, despite needing further clinical validation, molecular biomarkers have emerged as promising tools for enhancing prognostication. This manuscript highlights the ongoing research attempts to define treatment paradigms effectively and evaluates the potential of emerging options, ultimately aiming to improve patient care and outcomes in this complex clinical scenario.

Current guidelines recommend cold snare polypectomy for polyps less than 10 mm in size. Conversely, endoscopic mucosal resection is still the preferred technique for larger polyps. Concerns regarding cold snare polypectomy for larger polyps revolve around the difficulty in conducting en-bloc resection (resulting in piecemeal removal), and the potential for local residual polyp tissue and a high rate of recurrence. On the other hand, cold snare technique has the advantages of shortening procedure time, reducing delayed bleeding risks and lowering cost of treatment. Numerous ongoing and recent studies are focused on evaluating the risks and benefits of this technique for polyps larger than 10 mm, with the goal of providing clear guidelines in the near future. The aim of this editorial is to provide our readers with an overview regarding this subject and the latest developments surrounding it.

Multisystem inflammatory syndrome in adults (MIS-A) is a rare but severe disease occurring several weeks after severe acute respiratory syndrome coronavirus 2 infection. It develops in adults with inflammation of different organs including the gastrointestinal tract, heart, kidneys, skin and hematopoietic system.

We present a 58-year-old Chinese man diagnosed with MIS-A. His chief complaints were fever, generalized fatigue and anorexia, accompanied with rashes on his back. Further examination showed cardiac, renal and liver injury. He had melena and gastroscopy indicated esophageal ulcer and severe esophagitis. Repeated blood and sputum culture did not show growth of bacteria or fungi. Antibiotic treatment was stopped due to unsatisfactory performance. His condition improved after prednisone and other supportive treatment.

Gastrointestinal involvement in MIS-A is not uncommon. Intestinal involvement predominates, and esophageal involvement is rarely reported. Esophageal ulcer with bleeding could also be a manifestation of MIS-A.

New markers are needed to improve the effectiveness of serological screening for atrophic gastritis.

To develop a cost-effective method for serological screening of atrophic gastritis with a high level of sensitivity.

Of the 169 patients with atrophic gastritis, selected by the visual endoscopic Kimura-Takemoto method, 165 showed histological mucosal atrophy using the updated Kimura-Takemoto method. All 169 patients were examined for postprandial levels of gastrin-17 (G17) and pepsinogen-1 (PG1) using GastroPanel® (Biohit Plc, Helsinki, Finland).

We used the histological standard of five biopsies of the gastric mucosa, in accordance with the Kimura-Takemoto classification system to assess the sensitivity of G17 in detecting gastric mucosal atrophy. We also compared the morpho-functional relationships between the detected histological degree of gastric mucosal atrophy and the serological levels of G17 and PG1, as the markers of atrophic gastritis. The sensitivity of postprandial G17 was 62.2% for serological levels of G17 (range: 0-4 pmol/L) and 100% for serological G17 (range: 0-10 pmol/L) for the detection of monofocal severe atrophic gastritis. No strong correlation was found between the levels of PG1 and degree of histological atrophy determined by the Kimura-Takemoto classification system to identify the severity of mucosal atrophy of the gastric corpus. In the presented clinical case of a 63-year-old man with multifocal atrophic gastritis, there is a pronounced positive long-term dynamics of the serological marker of atrophy - postprandial G17, after five months of rennet replacement therapy.

Serological screening of multifocal atrophic gastritis by assessment of postprandial G17 is a cost-effective method with high sensitivity. Postprandial G17 is an earlier marker of regression of atrophic gastritis than a morphological examination of a gastric biopsy in accordance with the Sydney system. Therefore, postprandial G17 is recommended for dynamic monitoring of atrophic gastritis after treatment.

Schistosomiasis, officially named as a neglected tropical disease by The World Health Organization, is a serious parasitic disease caused by trematode flukes of the genus Schistosoma. It is a common infectious disease, endemic in more than 78 countries. The disease can involve various organs and poses far-reaching public health challenges.

Here, we present a series of five patients with variable presentations: an asymptomatic patient who was diagnosed with colonic schistosomiasis upon screening colonoscopy; 2 patients with clinical suspicion of colonic cancer; and 2 patients with a clinical diagnosis of inflammatory bowel disease. All patients were subsequently confirmed to have colonic schistosomiasis after colonoscopy and histopathologic examination. The clinical manifestations, colonoscopy features and histologic findings of the patients are described. Most of the patients showed significant clinical improvement following administration of oral praziquantel.

Intestinal schistosomiasis can present with features mimicking other gastrointestinal conditions. This disease should be a diagnostic consideration in patients who live in or have traveled to endemic areas.

Malignant gastric outlet obstruction (mGOO) is a major condition affecting patients with periampullary tumors, including pancreatic cancer. The current treatment options include surgical gastroenterostomy, endoscopic stenting and more recently EUS-guided gastroenterostomy. Most studies comparing the outcomes of the three procedures focus on technical success, clinical success and safety. Several "occult" outcomes relevant to the patient's viewpoints and perspective may ultimately impact on cancer-related and overall survival, such as body mass composition, nutritional biomarkers, chemotherapy tolerance and patient-reported quality of life. The aim of this review is to provide an overview of potential key outcomes that should be explored in future comparative research around mGOO treatment options.

Non-variceal upper gastrointestinal (GI) bleeding is a significant cause of morbidity and mortality. Traditionally, through-the-scope (TTS) clips, thermal therapy, and injection therapies are used to treat GI bleeding. In this review, we provide an overview of novel endoscopic treatments that can be used to achieve hemostasis. Specifically, we discuss the efficacy and applicability of over-the-scope clips, hemostatic agents, TTS doppler ultrasound, and endoscopic ultrasound, each of which offer an effective method of reducing rates of GI rebleeding.

Portal vein injury is an uncommon complication of endoscopic retrograde cholangiopancreatography (ERCP), for which stent malpositioning in the portal vein is very rare and can lead to fatal events. We report a case of biliary stent migration to the portal vein and a novel method for its safe removal under the guidance of portal angiography. Moreover, we reviewed the literature and summarized reports on the identification and management of this condition.

A 59-year-old woman with pancreatic cancer presented with abdominal pain and a high fever 20 days after the placement of two plastic biliary stents under the guidance of ERCP. Blood cultures and laboratory tests revealed sepsis, which was treated with antibiotics. A contrast-enhanced computed tomography scan revealed that one of the biliary stents in the main portal vein was malpositioned. To safely remove the stent, portal angiography was performed to visualize the portal vein and to allow the management of any bleeding. The two stents were removed without obvious bleeding, and an uncovered self-expanding metal stent was placed in the common bile duct for drainage. The patient had an uneventful 6-month follow-up period, except for self-resolving portal vein thrombosis.

The combination of endoscopic and angiographic techniques allowed uneventful management of stent malposition in the portal vein.

Worldwide, a majority of routine endoscopic procedures are performed under some form of sedation to maximize patient comfort. Propofol, benzodiazepines and opioids continue to be widely used. However, in recent years, Remimazolam is gaining immense popularity for procedural sedation in gastrointestinal (GI) endoscopy. It is an ultra-short-acting benzodiazepine sedative which was approved by the Food and Drug Administration in July 2020 for use in procedural sedation. Remimazolam has shown a favorable pharmacokinetic and pharmacodynamic profile in terms of its non-specific metabolism by tissue esterase, volume of distribution, total body clearance, and negligible drug-drug interactions. It also has satisfactory efficacy and has achieved high rates of successful sedation in GI endoscopy. Furthermore, studies have demonstrated that the efficacy of Remimazolam is non-inferior to Propofol, which is currently a gold standard for procedural sedation in most parts of the world. However, the use of Propofol is associated with hemodynamic instability and respiratory depression. In contrast, Remimazolam has lower incidence of these adverse effects intra-procedurally and hence, may provide a safer alternative to Propofol in procedural sedation. In this comprehensive narrative review, highlight the pharmacologic characteristics, efficacy, and safety of Remimazolam for procedural sedation. We also discuss the potential of Remimazolam as a suitable alternative and how it can shape the future of procedural sedation in gastroenterology.

Video-capsule endoscopy (VCE) is an efficient tool that has proven to be highly useful in approaching several gastrointestinal diseases. VCE was implemented in Colombia in 2003, however current characterization of patients undergoing VCE in Colombia is limited, and mainly comes from two investigations conducted before the SARS-CoV-2 pandemic period.

To describe the characteristics of patients undergoing VCEs and establish the main indications, findings, technical limitations, and other outstanding features.

A descriptive study was carried out using data from reports of VCE (PillCam SB3 system) use in a Gastroenterology Unit in Bogotá, Colombia between September 2019 and January 2023. Demographic and clinical variables such as indication for the VCE, gastric and small bowel transit times (GTT, SBTT), endoscopic preparation quality, and limitations were described [n (%), median (IQR)].

A total of 133 VCE reports were analyzed. Most were in men with a median age of 70 years. The majority had good preparation (96.2%), and there were technical limitations in 15.8% of cases. The main indications were unexplained anemia (91%) or occult bleeding (23.3%). The median GTT and SBTT were 14 and 30 minutes, respectively. The frequencies of bleeding stigma (3.79%) and active bleeding (9.09%) were low, and the most frequent abnormal findings were red spots (28.3%), erosions (17.6%), and vascular ectasias (12.5%).

VCE showed high-level safety. The main indication was unexplained anemia. Active bleeding was the most frequent finding. Combined with artificial intelligence, VCE can improve diagnostic precision and targeted therapeutic interventions.

The outflow of pancreatic juice into the duodenum is often impaired in pancreatic inflammatory diseases. The basis of interventional treatment in these cases is anatomical transpapillary access of the main pancreatic duct during endoscopic retrograde cholangiopancreatography (ERCP), which ensures the physiological outflow of pancreatic juice into the lumen of the digestive tract. However, in some patients, anatomical changes prevent transpapillary drainage of the main pancreatic duct. Surgery is the treatment of choice in such cases.

To evaluate the effectiveness and safety of endoscopic pancreaticogastrostomy under endoscopic ultrasound (EUS) guidance.

Retrospective analysis of treatment outcomes of all patients with acute or chronic pancreatitis who underwent endoscopic pancreatogastric anastomosis under EUS guidance in 2018-2023 at the Department of General, Gastroenterological and Oncological Surgery, Ludwik Rydygier Collegium Medicum in Bydgoszcz, Nicolaus Copernicus University in Toruń, Poland.

In 9 patients [7 men, 2 women; mean age 53.45 (36-66) years], endoscopic pancreatogastric anastomosis under EUS guidance was performed because of the lack of transpapillary access during ERCP. Narrowing of the main pancreatic duct at the head of the pancreas was observed in 4/9 patients (44.44%). Pancreatic fragmentation (disconnected pancreatic duct syndrome) was diagnosed in 3/9 patients (33.33%). In 2/9 patients (22.22%), narrowing of the pancreatoenteric anastomosis was observed after pancreaticoduodenectomy. Technical success of endoscopic pancreaticogastrostomy was observed in 8/9 patients (88.89%). Endotherapeutic complications were observed in 2/9 patients (22.22%). Clinical success was achieved in 8/9 patients (88.89%). The mean follow-up period was 451 (42-988) d. Long-term success of endoscopic pancreatogastric anastomosis was achieved in 7/9 patients (77.78%).

Endoscopic pancreaticogastrostomy under EUS guidance is an effective and safe treatment method, especially in the absence of transpapillary access to the main pancreatic duct.

The functional lumen imaging probe (FLIP) is a Food and Drug Administration approved tool to aid the diagnosis and management of esophageal disorders. However, widespread adoption of FLIP remains limited and its utility in high-volume practices remains unclear.

To analyze large sample data on clinical use of FLIP and provide insight on several technical aspects when performing FLIP.

We conducted a retrospective comparative and descriptive analysis of FLIP procedures performed by a single provider at an academic medical center. There was a total of 398 FLIP procedures identified. Patient medical records were reviewed and data regarding demographics and procedural details were collected. Statistical tests, including chi-squared, t-test, and multivariable logistic and linear regression, were performed.

There was an increase in FLIP cases with each successive time period of 13 months (n = 68, 146, 184, respectively) with notable rises specifically for indications of dysphagia and gastroesophageal reflux disease. There was a shift toward use of the longer FLIP balloon catheter for diagnostic purposes (overall 70.4% vs 29.6%, P < 0.01). Many cases (42.8%) were performed in conjunction with other diagnostics/interventions, such as dilation and wireless pH probe placement. Procedures were nearly equally performed with anesthesia vs moderate sedation (51.4% anesthesia), with no major complications. Patients who had anesthesia were less likely to have recurrent antegrade contractions [odds ratio (OR) = 0.4, 95%CI: 0.3-0.8] and were also more likely to have absent contractility (OR = 2.4, 95%CI: 1.3-4.4).

FLIP cases have increased in our practice with expanding indications for its use. Given limited normative data, providers should be aware of several potential technical issues, including the possible impact of sedation choice when assessing esophageal motility patterns.

Routine outpatient endoscopy is performed across a variety of outpatient settings. A known risk of performing endoscopy under moderate sedation is the potential for over-sedation, requiring the use of reversal agents. More needs to be reported on rates of reversal across different outpatient settings. Our academic tertiary care center utilizes a triage tool that directs higher-risk patients to the in-hospital ambulatory procedure center (APC) for their procedure. Here, we report data on outpatient sedation reversal rates for endoscopy performed at an in-hospital APC vs at a free-standing ambulatory endoscopy digestive health center (AEC-DHC) following risk stratification with a triage tool.

To observe the effect of risk stratification using a triage tool on patient outcomes, primarily sedation reversal events.

We observed all outpatient endoscopy procedures performed at AEC-DHC and APC from April 2013 to September 2019. Procedures were stratified to their respective sites using a triage tool. We evaluated each procedure for which sedation reversal with flumazenil and naloxone was recorded. Demographics and characteristics recorded include patient age, gender, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, procedure type, and reason for sedation reversal.

There were 97366 endoscopic procedures performed at AEC-DHC and 22494 at the APC during the study period. Of these, 17 patients at AEC-DHC and 9 at the APC underwent sedation reversals (0.017% vs 0.04%; P = 0.06). Demographics recorded for those requiring reversal at AEC-DHC vs APC included mean age (53.5 ± 21 vs 60.4 ± 17.42 years; P = 0.23), ASA class (1.66 ± 0.48 vs 2.22 ± 0.83; P = 0.20), BMI (27.7 ± 6.7 kg/m2 vs 23.7 ± 4.03 kg/m2; P = 0.06), and female gender (64.7% vs 22%; P = 0.04). The mean doses of sedative agents and reversal drugs used at AEC-DHC vs APC were midazolam (5.9 ± 1.7 mg vs 8.9 ± 3.5 mg; P = 0.01), fentanyl (147.1 ± 49.9 μg vs 188.9 ± 74.1 μg; P = 0.10), flumazenil (0.3 ± 0.18 μg vs 0.17 ± 0.17 μg; P = 0.13) and naloxone (0.32 ± 0.10 mg vs 0.28 ± 0.12 mg; P = 0.35). Procedures at AEC-DHC requiring sedation reversal included colonoscopies (n = 6), esophagogastroduodenoscopy (EGD) (n = 9) and EGD/colonoscopies (n = 2), whereas APC procedures included EGDs (n = 2), EGD with gastrostomy tube placement (n = 1), endoscopic retrograde cholangiopancreatography (n = 2) and endoscopic ultrasound's (n = 4). The indications for sedation reversal at AEC-DHC included hypoxia (n = 13; 76%), excessive somnolence (n = 3; 18%), and hypotension (n = 1; 6%), whereas, at APC, these included hypoxia (n = 7; 78%) and hypotension (n = 2; 22%). No sedation-related deaths or long-term post-sedation reversal adverse outcomes occurred at either site.

Our study highlights the effectiveness of a triage tool used at our tertiary care hospital for risk stratification in minimizing sedation reversal events during outpatient endoscopy procedures. Using a triage tool for risk stratification, low rates of sedation reversal can be achieved in the ambulatory settings for EGD and colonoscopy.

Glucagon-like peptide receptor agonists (GLP-1RA) are used to treat type 2 diabetes mellitus and, more recently, have garnered attention for their effectiveness in promoting weight loss. They have been associated with several gastrointestinal adverse effects, including nausea and vomiting. These side effects are presumed to be due to increased residual gastric contents. Given the potential risk of aspiration and based on limited data, the American Society of Anesthesiologists updated the guidelines concerning the preoperative management of patients on GLP-1RA in 2023. They included the duration of mandated cessation of GLP-1RA before sedation and usage of "full stomach" precautions if these medications were not appropriately held before the procedure. This has led to additional challenges, such as extended waiting time, higher costs, and increased risk for patients. In this editorial, we review the current societal guidelines, clinical practice, and future directions regarding the usage of GLP-1RA in patients undergoing an endoscopic procedure.

Duodenal Brunner's gland hyperplasia (BGH) is a therapeutic target when complications such as bleeding or gastrointestinal obstruction occur or when malignancy cannot be ruled out. Herein, we present a case of large BGH treated with endoscopic mucosal resection (EMR).

An 83-year-old woman presented at our hospital with dizziness. Blood tests revealed severe anemia, esophagogastroduodenoscopy showed a 6.5 cm lesion protruding from the anterior wall of the duodenal bulb, and biopsy revealed the presence of glandular epithelium. Endoscopic ultrasonography (EUS) demonstrated relatively high echogenicity with a cystic component. The muscularis propria was slightly elevated at the base of the lesion. EMR was performed without complications. The formalin-fixed lesion size was 6 cm × 3.5 cm × 3 cm, showing nodular proliferation of non-dysplastic Brunner's glands compartmentalized by fibrous septa, confirming the diagnosis of BGH. Reports of EMR or hot snare polypectomy are rare for duodenal BGH > 6 cm. In this case, the choice of EMR was made by obtaining information on the base of the lesion as well as on the internal characteristics through EUS.

Large duodenal lesions with good endoscopic maneuverability and no evident muscular layer involvement on EUS may be resectable via EMR.

At present, laparoscopic cholecystectomy (LC) is the main surgical treatment for gallstones. But, after gallbladder removal, there are many complications. Therefore, it is hoped to remove stones while preserving the function of the gallbladder, and with the development of endoscopic technology, natural orifice transluminal endoscopic surgery came into being.

To compare the quality of life, perioperative indicators, adverse events after LC and transgastric natural orifice transluminal endoscopic gallbladder-preserving surgery (EGPS) in patients with gallstones.

Patients who were admitted to The First Affiliated Hospital of Xinjiang Medical University from 2020 to 2022 were retrospectively collected. We adopted propensity score matching (1:1) to compare EGPS and LC patients.

A total of 662 cases were collected, of which 589 cases underwent LC, and 73 cases underwent EGPS. Propensity score matching was performed, and 40 patients were included in each of the groups. In the EGPS group, except the gastrointestinal defecation (P = 0.603), the total score, physical well-being, mental well-being, and gastrointestinal digestion were statistically significant compared with the preoperative score after surgery (P < 0.05). In the LC group, except the mental well-being, the total score, physical well-being, gastrointestinal digestion, the gastrointestinal defecation was statistically significant compared with the preoperative score after surgery (P < 0.05). When comparing between groups, gastrointestinal defecation had significantly difference (P = 0.002) between the two groups, there was no statistically significant difference in the total postoperative score and the other three subscales. In the surgery duration, hospital stay and cost, LC group were lower than EGPS group. The recurrence factors of gallstones after EGPS were analyzed: and recurrence was not correlated with gender, age, body mass index, number of stones, and preoperative score.

Whether EGPS or LC, it can improve the patient's symptoms, and the EGPS has less impact on the patient's defecation. It needed to, prospective, multicenter, long-term follow-up, large-sample related studies to prove.
