Current Trends in the Management of a Complex Polyp: Endoscopy versus Surgery

Many colorectal cancers arise from either adenomatous polyps or sessile serrated lesions. However, due to the implementation of screening guidelines at the age of 45 years and the ability to perform therapeutic endoscopic polyp resections, the incidence and mortality of colorectal cancer has been decreasing in the United States. Polyps can be distinguished not only by pathology, but characterized by their complexity depending on the size, location, and morphology. Historically, polyps that were endoscopically more challenging to resect were referred for surgical resection. However, due to rapid advancement in endoscopic techniques and availability of tools, many of these complex polyps can be safely and effectively resected endoscopically. In this section, we review the different methods and potential challenges associated with endoscopic resection techniques including endoscopic mucosal resection, endoscopic submucosal dissection, or endoscopic full-thickness resection of a complex polyp.

Sloughing Esophagitis in the Pediatric Age Group: Clinicopathologic Characteristics of 12 Cases

BACKGROUND

Sloughing esophagitis (esophagitis dissecans superficialis) is a benign, self-limited condition of uncertain etiology. It is most common in adults; pediatric literature is limited.

METHODS

Ten years of records were queried for esophageal biopsies containing terms "sloughing" and/or "dissecans." Histologic inclusion criteria were "two-tone" appearance, sloughing/flaking of superficial epithelium, and parakeratosis. Degree of inflammation was documented and medical records were reviewed.

RESULTS

Fourteen patients were identified ranging from 1 to 19 years (mean = 14 years) and included 3 males and 11 females. Two patients were excluded due to lack of histologic criteria/unavailability of slides for review. Of the 12 cases evaluated, 6 showed a classic inflammation pattern, 5 had minimal or no inflammation, and 1 displayed severe acute inflammation. Endoscopy did not correlate with histology. Sloughing esophagitis is traditionally associated with Selective serotonin reuptake inhibitors (SSRI) use; though 5/12 patients were taking medication for anxiety or depression, only 3 were taking SSRIs. Five patients had marijuana/cannabinoid exposure.

CONCLUSION

Sloughing esophagitis can present in the pediatric population across a wide age range. Similar to the adult population, etiology may be linked to medications. Additional associations such as marijuana/cannabinoid exposure need further clinical investigation. A subset of patients had a history of or subsequently developed eosinophilic esophagitis.

Konjac glucomannan/sodium alginate/ε-poly-l-lysine hydrogel promotes esophageal and colonic wound healing

Endoscopic submucosal dissection (ESD) is widely used to treat gastrointestinal mucosal and submucosal lesions. However, it may cause bleeding, perforation, and stricture. Although these complications can be avoided by introducing materials such as polyglycolic acid and carboxymethyl cellulose sheets, such approaches are expensive and time-consuming. Herein, we report a hydrogel prepared by combining a colloidal solution composed of konjac glucomannan (KGM) and sodium alginate (SA) and a fixative solution containing ε-poly-l-lysine (ε-PLL) and calcium chloride. The two solutions were mixed on the wound surface to form the KGM/SA/ε-PLL hydrogel through hydrogen bonds, coordination bonds, and electrostatic attraction. The effectiveness and convenience of applying the KGM/SA/ε-PLL hydrogel to promote wound healing in the esophagus and colon were assessed in vitro and in vivo. We found that the hydrogel stimulated epithelial proliferation, reduced inflammation, promoted recapillarization, and inhibited fibrosis in the esophagus and colon. Therefore, the KGM/SA/ε-PLL hydrogel is an effective and convenient agent that can promote post-ESD wound healing and is recommended for ulcer bed protection in daily clinical practice.

Hydrogel-Impregnated Robust Interlocking Nano Connector (HiRINC) for Noninvasive Anti-Migration of Esophageal Stent

Migration of implanted self-expandable metallic stent (SEMS) in the malignant or benign esophageal stricture is a common complication but not yet resolved. Herein, this research develops a hydrogel-impregnated robust interlocking nano connector (HiRINC) to ensure adhesion and reduce the mechanical mismatch between SEMSs and esophageal tissues. Featuring a network-like porous layer, HiRINC significantly enhances adhesion and energy dissipation during esophageal peristalsis by utilizing mechanical interlocking and increasing hydrogen bonding sites, thereby securing SEMS to tissues. The anti-swelling property of HiRINC prevents excessive hydrogel expansion, avoiding esophageal blockage. Ex vivo and in vivo adhesion tests confirm that the HiRINC outperforms flat surfaces without RINC structures and effectively prevents stent migration. HiRINC-coated SEMS maintains its position and luminal patency, minimizing stent-induced tissue hyperplasia and inflammatory responses in rat and porcine esophageal models during the 4-week follow-up. This novel HiRINC-SEMS can ensure anti-migration and prolonged stent patency in the rat and porcine esophagus and seems to be expanded to other nonvascular luminal organs and various implantable metallic devices.

Imaging of Iatrogenic Injuries to the Bowel

This review discusses the ways in which the health care provider (or more broadly, the provision of medical care) can cause harm to the bowel and highlights the appearance of such untoward events on imaging. The etiologies are myriad, and as such, the radiologist must remain vigilant in identifying the presence of suspected and unsuspected injuries. Specific attention is given to complications from medication and external radiation therapy, as these interventions and their timing are often not known by the radiologist.

Is Transumbilical Laparoscopic-assisted Appendectomy Better than Laparoscopic Appendectomy in Children? A Randomized Controlled Study

Aim

To compare the gold standard method of managing acute appendicitis; laparoscopic appendectomy (LA) to transumbilical laparoscopic-assisted appendectomy (TULAA).

Methods

A randomized clinical study of consecutive pediatric patients (age under 13 years) undergoing appendectomy for noncomplicated acute appendicitis was conducted at a tertiary center in Jordan. Data collected included; perioperative parameters, operative time, gas time, postoperative hospital stay, pathology, complications, pain, and cost.

Results

Out of the 50 initially enrolled patients, 47 were included in the analysis (25 in TULAA group [53.2%], 22 in LA group [46.8%]), of which only 12% and 31% of patients had perforated appendicitis, in the TULAA group and LA group consecutively. No early intraoperative complications were observed. Postoperative complications were seen in 4.8% of the LA group and 4% in the TULAA group. TULAA had significantly shorter operative time, lower gas flow, gas time, gas pressure levels, and more cases (68%) were operated without gas use compared to LA. Pain relief, diet resumption, cosmetic, and hospital stay did not significantly differ between the groups. The cosmetic outcome was slightly better in the TULAA group but not statistically significant.

Conclusion

TULLA offers an alternative approach to LA for acute appendicitis and may be of benefit in resource-poor institutions whilst maintaining the benefits of the minimally invasive approach. This study has demonstrated a significantly reduced wound infection, operative time, and gaseous insufflation for TULLA compared to LA. Further studies to demonstrate its feasibility in complicated appendicitis may be warranted.

Prevalence of Carbapenemase-producing organisms (CPO) colonization before and after endoscopic retrograde cholangiopancreatography (ERCP): A prospective observational study

INTRODUCTION

Risk of transmission of carbapenemase-producing organisms (CPO) from duodenoscopes has been widely described and is now considered a well-known threat. Data on infection rates are limited to case series and confined to the setting of infection outbreaks. To date, data on universal screening for multidrug-resistant microorganisms of patients referring to the Endoscopy service are extremely scant.

AIM

to evaluate the overall incidence of CPO colonization after endoscopic retrograde cholangiopancreatography (ERCP).

METHODS

All consecutive patients undergoing ERCP at our Service were evaluated. All enrolled patients underwent rapid rectal swab for KPC genes 2-24 h before the endoscopic procedure, with Xpert Carba-R rapid detection swabs. 72 h after ERCP, patients underwent a second rapid rectal swab for CPO.

RESULTS

from July 2022 to 15th November 2023 539 patients referring to the Endoscopy Unit for ERCP were evaluated. Of these, 16 had already a known colonization for MDR. The other 523 patients were screened: 10 resulted positive for CPO. Of the remaining 513 patients, 355 underwent post-procedural swab, and 9 (2,5 %) had a rectal colonization from CPO.

CONCLUSIONS

duodenoscope-related infections are an open issue. Routine screening with anal swabs could provide early recognition of infection outbreaks and identification of high-risk cases to drive proper resource allocation.

Esophageal stricture due to corrosive substance ingested and delayed management: A case report

Corrosive substance ingestion is a medical emergency that can lead to poor outcomes, though prompt and adequate treatment has been carried out, particularly in cases of delayed management. An Indonesian man, 36 years old, complained of continually vomiting after meals caused by ingesting a corrosive substance 3 months earlier, which had an impact wight loss of 25 kg. Besides, he also experienced tenderness in the epigastric and left hypochondriac areas. The first endoscopic examination revealed esophageal stricture. In the second endoscopy, dilation was performed with balloon-controlled radial expansion (CRE) and showed a stricture in the pyloric sphincter and corrosive damage IIIA, according to Zargar's classification. Despite 14 times of endoscopic performed combined with dilation and Triamcinolone Acetonide injection, the esophageal and pyloric strictures recurrence occurred several times. Therefore, he was stenting into esophageal patent to keep the lumen diameter constant. Esophageal stricture is a complication of corrosive substance ingestion that requires lengthy treatment. Local steroids are less likely to cause challenges during esophageal dilatation than systemic or oral steroids. Corrosive substance ingestion negatively impacts the upper gastrointestinal system; one of the case is esophageal stricture, which requires lengthy management of lumen narrowing recurrence.

A thin cryobiopsy device compatible with transnasal endoscopy for the gastrointestinal tract

Luminal organ biopsies are critical for disease diagnosis and are obtained using single-bite forceps inserted through the working channel of large endoscopes. Procedures using these endoscopes frequently require patient sedation or anesthesia and may not be feasible for use in pediatric patients. Additionally, forceps-derived biopsies can suffer from difficulty maintaining tissue orientation, crush artifacts, and lack of precise control of biopsy depth. The high cost and risks of anesthesia and sedation have driven the development of smaller endoscopes for unsedated procedures. However, reduced endoscope size limits working-channel dimensions, restricting biopsy forceps to sizes that may yield insufficient or nondiagnostic samples. To address these limitations, we developed an image-guided, depth-controlled, ultrasmall-diameter (1.2-millimeters) cryobiopsy device (μCryoProbe). We optimized the coolant flow profile into the device to enhance tissue freezing, optimizing device-tissue contact time and freezing depth. We tested the device for gastrointestinal biopsy collection in ex vivo preclinical tissues, in an in vivo porcine model, and in sedated human participants. Dimensions and quality of mucosal cryobiopsies from esophagus, stomach, and duodenum were compared with those of forceps-derived biopsies, and it was found that the μCryoProbe device consistently produced high-quality biopsies with optimal tissue orientation and no evidence of crush artifacts. We also demonstrated the ability to capture gastrointestinal biopsies from sedated human participants. By capturing large, well-oriented samples using a small-diameter biopsy tool, this technology has the potential to shift procedures from large to small endoscopes, reducing the need for sedation and improving patient diagnosis through the acquisition of tissue samples with better quality.

EASL Clinical Practice Guidelines on the management of extrahepatic cholangiocarcinoma

Recent years have witnessed significant advances in the imaging, molecular profiling, and systemic treatment of cholangiocarcinoma (CCA). Despite this progress, the early detection, precise classification, and effective management of CCA remain challenging. Owing to recent developments and the significant differences in CCA subtypes, EASL commissioned a panel of experts to draft evidence-based recommendations on the management of extrahepatic CCA, comprising distal and perihilar CCA. Particular attention is given to the need for accurate classification systems, the integration of emerging molecular insights, and practical strategies for diagnosis and treatment that reflect real-world clinical scenarios.

Endoscopic ultrasound with submucosal saline injection improves the accuracy of T1a and T1b staging in superficial esophageal squamous cell carcinoma

Background

Endoscopic ultrasound (EUS) is important for diagnosing and staging esophageal cancer. However, substantial variability in the diagnostic and staging accuracy of EUS, especially in early-stage cancers, affects patients' treatment choices and quality of life.

Aims

To explore whether conventional endoscopic ultrasonography (EUS-C) combined with submucosal saline injection (EUS-SSI) improves diagnostic accuracy in preoperative T1a and T1b staging in superficial esophageal squamous cell carcinoma (SESCC).

Methods

Patients with SESCC first underwent EUS-C. Then, they received SSI and underwent a repeat EUS. The diagnostic accuracy of EUS-C and EUS-SSI was evaluated based on the final postoperative pathology results.

Results

A total of 92 patients with endoscopically diagnosed SESCC were included in the study. Postoperative pathology confirmed superficial SESCC in all patients (T1a stage, n = 77; T1b stage, n = 15). EUS-C correctly identified 54 of 77 patients with T1a cancer and nine of 15 patients with T1b cancer, whereas EUS-SSI identified 68 of 77 patients with T1a cancer and 10 of 15 patients with T1b cancer. EUS-SSI was more accurate than EUS-C in diagnosing T1a and T1b stage SESCC (84.8 and 68.5%, respectively).

Conclusion

EUS-SSI differentiates between T1a and T1b stages of superficial SESCC with better diagnostic accuracy than EUS-C, thereby reducing the rate of over-staging.

Carbamazepine-Induced DRESS Complicated by HLH and VBDS: A Case Report

Background

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a severe systemic disorder characterized by fever, rash, and multi-organ involvement, often complicated by drug-induced liver injury. Hemophagocytic lymphohistiocytosis (HLH) and vanishing bile duct syndrome (VBDS) are rare but life-threatening complications that can be triggered by antiepileptic drugs such as carbamazepine. Given the high mortality associated with these conditions, early recognition and timely intervention are crucial for improving patient outcomes.

Case

We report a unique case of an elderly woman who developed DRESS syndrome after using carbamazepine, complicated by both HLH and VBDS. The patient exhibited typical DRESS symptoms, including fever, rash, and eosinophilia, alongside signs of HLH such as hemocytopenia and elevated ferritin levels; along with persistent significant hyperbilirubinemia and coagulation abnormalities.

Results

After six months, liver function showed substantial improvement, with no signs of HLH recurrence. Additionally, our review of HLH cases induced by antiepileptic drugs highlights that the absence of eosinophilia, hemocytopenia, and elevated ferritin levels is key for early HLH identification.

Conclusion

Our findings highlight key diagnostic indicators for early HLH recognition in antiepileptic drug-induced DRESS, especially the absence of eosinophilia. This case represents the first successful management of DRESS syndrome complicated by HLH and VBDS without liver transplantation in the past decade, emphasizing the critical role of early identification and prompt, targeted treatment strategies in optimizing patient outcomes.

FIGO guideline on liver disease and pregnancy

The number of women entering pregnancy with chronic liver disease is rising. Gestational liver disorders affect 3% of the pregnant population. Both can be associated with significant maternal and fetal morbidity and mortality. European guidance has recently been published to inform management. This FIGO (the International Federation of Gynecology & Obstetrics) guideline aims to use the latest evidence to inform practice relevant to a global population. The immediate past and present chairs of FIGO's Committee on the Impact of Long-term Health invited the Chair of the European guideline, alongside two trainees with an interest in liver disorders in pregnancy, to develop a guideline relevant to a global audience, thus serving the real-world population and fulfilling FIGO's ambition to enhance their global voice for women's health. Experts in the field with experience in managing liver disorders in pregnancy from a diverse selection of continents helped to develop a guideline. A guideline has been developed including the most common pre-existing and gestational liver disorders. Evidence-based best practice recommendations are summarized in addition to pragmatic recommendations. Printable tables/figures are included in the guideline for ease of use. These include a table of normal ranges of commonly used blood tests, a table outlining safety of investigations, and a table of delivery considerations relevant to a global audience. Figures designed to summarize each section of the guideline and the multidisciplinary approach to managing liver disorders in pregnancy are also included. This guideline incorporates guidance for a global audience aimed at improving the management of women with pre-existing and new liver disease in pregnancy.

Multisociety guidance for sterilization and high-level disinfection

SHEA, in partnership with ASGE, APIC, AAMI, AORN, HSPA, IDSA, SGNA, and The Joint Commission, developed this multisociety infection prevention guidance document for individuals and organizations that engage in sterilization or high-level disinfection (HLD). This document follows the CDC Guideline for Disinfection and Sterilization in Healthcare Facilities. This guidance is based on a synthesis of published scientific evidence, theoretical rationale, current practices, practical considerations, writing group consensus, and consideration of potential harm when applicable. The supplementary material includes a summary of recommendations. The guidance provides an overview of the Spaulding Classification and considerations around manufacturers' instructions for use (MIFUs). Its recommendations address: point-of-use treatment prior to sterilization or HLD, preparation of reusable medical devices at the location of processing, sterilization, and immediate use steam sterilization (IUSS), HLD of lumened and non-lumened devices, processing of reusable medical devices used with lubricating or defoaming agents, monitoring for effectiveness of processing, handling of devices after HLD, augments and alternatives to HLD, processing of investigational devices, tracking of reusable medical devices, and approaches to implementation.

Efficacy of low-dose esketamine combined with propofol/etomidate mixture in painless gastroscopy anesthesia

BACKGROUND

Propofol/etomidate mixture is a common anesthetic for painless gastroscopy, but the anesthetic effect is not satisfactory. Esmketamine can achieve ideal anesthetic effect, and low-dose esmketamine has more reliable safety. However, the application of low-dose esmketamine combined with propofol/etomidate mixture in painless gastroscopy anesthesia has been less explored.

AIM

To evaluate the efficacy of low-dose esketamine combined with propofol/etomidate mixture in painless gastroscopy anesthesia.

METHODS

A prospective study was conducted on patients who were scheduled to undergo painless gastroscopy at the Hangzhou Traditional Chinese Medicine Hospital from June 2023 to June 2024. They were randomly divided into a control group and a combination group according to the random number table method. Both groups were given a mixture of propofol and etomidate, and the combination group was additionally given a low dose of esketamine. The anesthesia effects and incidence of adverse reactions (nausea and vomiting, hypotension, respiratory depression, and postoperative delirium) were compared between the two groups, as well as hemodynamic parameters [heart rate (HR) and mean arterial pressure (MAP)], respiratory parameters [respiratory rate (RR), arterial oxygen saturation] at the time of entering the room (T₁), starting sedation (T₂), inserting the gastroscope (T₃), withdrawing the gastroscope (T₄), and at the end of the operation (T₅), and cognitive function [mini-mental state examination (MMSE) score] at 15 min and 30 min after awakening.

RESULTS

The time to onset of anesthesia, time to recovery, and post-anesthesia care unit stay time in the combination group were shorter than those of the control group, and the number of additional anesthetic drugs and the total amount of additional anesthetic drugs used were less than those of the control group (P < 0.05). The interaction effect of HR, MAP, and RR at different time points between the two groups was statistically significant (P < 0.05). At T₁-T_2, the inter-group effects of the univariate repeated measures analysis of variance showed that there were no significant changes in HR, MAP, and RR in the two groups (P > 0.05). HR showed a trend of first increasing and then decreasing, while MAP showed a trend of first decreasing and then increasing at T₃-T₅ (P < 0.05). RR showed a decreasing trend at T₃-T₅ in the control group (P < 0.05). The inter-group effect of multivariate analysis of variance showed that the HR in the combination group was lower than that of the conventional group, while MAP and RR were higher at T₃-T₅ (P < 0.05). The results of univariate and multivariate analyses using the generalized estimating equation model showed that there were significant differences in HR, MAP, and RR among groups, times, and their interaction terms (P < 0.05). The MMSE scores of the combination group were higher than those of the control group at 15 minutes and 30 minutes after awakening (P < 0.05). The incidence of respiratory depression and delirium in the combination group was lower than that of the control group (P < 0.05).

CONCLUSION

The anesthetic effect of low-dose esketamine combined with propofol/etomidate mixture in painless gastroscopy anesthesia is good, which can maintain stable hemodynamics, reduce interference with breathing, accelerate postoperative cognitive function recovery, and reduce the incidence of respiratory depression and postoperative delirium.

Fistula closure technique using an esophageal stent and fixation method for gastrointestinal-airway fistula after esophageal cancer surgery

BACKGROUND

 The occurrence of a gastrointestinal-airway fistula after esophageal cancer surgery is a serious and fatal complication that can cause severe respiratory complications. It is a pathological condition requiring prompt intervention to avoid a fatal course. Conventionally, highly invasive surgical treatment has been selected for the treatment for gastrointestinal-airway fistula, but its difficulty and mortality risk cannot be neglected. Esophageal stent placement is useful as a nonoperative management for gastrointestinal-airway fistulas, but the success rate of fistula closure is not that high. Hence, an effective method that can solve technical problems to avoid intervention-related complications and increases the success rate of fistula closure by stent placement needs to be developed. We have achieved better results with our unique ingenuity for the management of esophageal stent placement; thus, we aimed to describe the details of the management methods.

METHODS

Our technique used in stent placement included endoscopic insertion of the self-expandable metallic stent and the fixation of the stent with a nylon thread and a transnasal catheter on the face. With this ingenuity, it becomes possible to reduce stent migration, and an easy and quick adjustment of its position in case of stent migration can be possible.

RESULTS

We have experienced successfully cured cases with our novel technique [five of seven cases (71.4%)] with a minimum indwelling period.

CONCLUSIONS

Our technique is feasible for use in the management of gastrointestinal-airway fistula after esophageal cancer surgery.

Calcifying fibrous tumor of stomach: a rare case report of an upper gastrointestinal bleeding

Introduction

Calcifying fibrous tumor (CFT) is an uncommon benign fibrous neoplastic lesion that may manifest as singular or multiple tumors and usually occurs in children or young adults. CFT originates in the muscularis propria of the stomach and is a very rare disease. Here, we report a case of gastric CFT with upper gastrointestinal bleeding.

Case information

A 39-year-old male was urgently referred to our hospital with haematemesis and melena that had developed over the course of 2 hours. Enhanced abdominal CT imaging revealed a nodular lesion, measuring approximately 3.2 × 2.1 × 1.6 cm, protruding from the posterior wall of the gastric body into the gastric lumen. The lesion exhibited scattered calcifications, smooth margins, and a CT attenuation value of 50 Hounsfield units (HU). Gastroscopic ultrasonography performed in the gastroenterology department revealed a semicircular submucosal mass with signs of active bleeding. Initially, the tumor was diagnosed as a gastrointestinal stromal tumor (GIST), and surgical intervention was undertaken due to ongoing hemorrhage. Postoperative histopathological examination confirmed the diagnosis of a gastric calcifying fibrous tumor (CFT).

Conclusion

CFT originating from the muscularis propria of the stomach is exceptionally rare, and the case presented here mimicked a gastric submucosal tumor (SMTs),clinicians should consider this differentia diagnosis when evaluating patients with suspected cases.

Small Bowel Tumors: A 7-Year Study in a Tertiary Care Hospital

(1) Background: Tumors of the small bowel represent 3-6% of gastrointestinal neoplasms and 3-6% of GI malignancies. The difficulties regarding the diagnosis are associated with larger tumors at the moment of the diagnosis and with advanced forms of malignant tumors, associated with a dismal prognosis. (2) Methods: We performed an observational, retrospective, cohort study that included patients with small bowel tumors admitted to the Craiova County Emergency Clinic Hospital between 1 January 2017 and 31 December 2023. The data were collected from the analysis of the patient's discharge documents from the Hippocrates computer system of the hospital and the evaluation of endoscopy databases. Patients under 16 years of age, those with no pathological confirmation of the malignancy, and those with insufficient data were excluded. (3) Results: A total of 80 cases of small bowel tumors were diagnosed; 72.5% were malignant, of which 10.3% were metastases. The most frequent primary malignant small bowel tumor was adenocarcinoma; two squamous cell carcinomas were noted. CT scans and upper digestive endoscopy represent the most frequent imaging methods for the diagnosis. The prognosis for malignant tumors was poor, with a 41% 5-year survival rate. (4) Conclusions: Small bowel tumors are rarely encountered, with 72.5% being malignant, and were diagnosed at large dimensions and in advanced stages for malignant tumors, with a dismal prognosis.

Latest Research Trends on the Management of Hemorrhoids

Hemorrhoids manifest with a range of symptoms and severities, prompting the development of various conservative, interventional, and surgical treatments. Selecting the most suitable treatment for each case is challenging, especially with the continuous evolution of new methods. This review aims to advance hemorrhoid treatment and research by exploring recent developments over the last five years. Conservative approaches have focused on isolating active ingredients from traditional herbal remedies to create new products and understand their mechanisms. In office-based treatments, advanced devices such as modified rubber band ligation and polymer clips with stronger binding forces have been introduced. Polidocanol in foam form has shown promise in sclerotherapy, while infrared coagulation is being replaced by alternative energy-based methods. Additionally, endoscopic office treatments and embolization of hemorrhoidal vessels via angiography are increasingly used as safer options for patients with high surgical risks or bleeding issues. Stapled hemorrhoidopexy has shifted to partial resection instead of complete circular resection, and hemorrhoidal artery ligation techniques have been reported to be effective when combined with stapled hemorrhoidopexy or excisional hemorrhoidectomy in severe cases. Evidence is growing that hemorrhoidal artery ligation remains effective even without Doppler guidance. With ongoing research into various methods, there is a need for scientific comparison and evaluation of their advantages and disadvantages, standardization of indicators and treatment protocols, and cost-effectiveness considerations. Surgeons should offer well-informed options and explanations to patients, based on a comprehensive understanding of available treatments.

A Systematic Review and Meta-Analysis on the Prevalence of Variants in the Pancreaticobiliary Duct Junction and Its Association with Cancer

Background/Objectives: The objective of this study was to describe the anatomical variants of the pancreaticobiliary junction and how its position or structural change could be associated with hepatic, duodenal, and pancreatic clinical complications. Methods: We searched MEDLINE, Scopus, Web of Science (WOS), Google Scholar, CINAHL, and EMBASE databases from their inception up to September 2024. Results: Two authors independently performed the search, study selection, data extraction, and assessed the methodological quality with an assurance tool for anatomical studies (AQUA). Finally, the pooled prevalence was estimated using a random effects model. A total of 59 studies with a total of 22,752 participants were included in this review. The overall prevalence of the anomalous pancreaticobiliary junction (APBJ) variant was 12% (95% CI = 6% to 18%). The prevalence of cancer associated with variants of APBJ was 29% (95% CI = 23% to 34%). Conclusions: In the present anatomical systematic review and meta-analysis, we found that a longer common channel correlated with a higher prevalence of bile duct or gallbladder malignancy, due to the backward flow of bile which occurs as a result of the position and distance of the bile ducts, as well as pancreatic failing. Hence, APBJs are of great interest for gastroduodenal surgeons.

Unmet Needs of Artificial Intelligence in Small Bowel Capsule Endoscopy

Small bowel capsule endoscopy (SBCE) has emerged in the past two decades as the cornerstone for assessing small bowel disorders, and its use is supported by several guidelines. However, there are several limitations, such as the considerable time required for gastroenterologists to review these videos and reach a diagnosis. To address these limitations, researchers have explored the integration of artificial intelligence in the interpretation of these videos. In our review, we explore the evolving and emerging role of artificial intelligence in SBCE and examine the latest advancements and ongoing studies in these areas, aiming at overcoming current limitations.

Incidental sclerosing angiomatoid nodular transformation of the spleen

Sclerosing angiomatoid nodular transformation (SANT) is a rare, often asymptomatic, tumour of the spleen, typically discovered incidentally during imaging for unrelated reasons. In this case, a SANT was discovered in the spleen of an otherwise healthy man in his 40s undergoing a CT for an unrelated issue. The mass was evaluated by MRI, F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT and sulfur colloid scintigraphy. The mass demonstrated gradual enhancement with central and radiating non-enhancing components in keeping with the previously described spoke-wheel enhancement pattern. The central components enhanced at the same rate as peripheral components while the non-enhancing components never filled in. The mass was slightly hypermetabolic relative to the liver on FDG PET/CT and demonstrated a sulfur colloid scintigraphic defect. It was removed en bloc by total splenectomy. Pathological evaluation revealed bosselated contours with nodules of vascular elements surrounded by an outer concentric rim of hyalinised fibrosis typical of SANT.

Predictive Factors of Post-ERCP Hepatic Decompensation in Patients with Cirrhosis: A Retrospective Case-Control Study

BACKGROUND AND AIM

Endoscopic retrograde cholangiopancreatography (ERCP) is a crucial diagnostic and therapeutic procedure in patients with cirrhosis; however, it carries the risk of post-procedural hepatic decompensation. This study aims to identify predictive factors associated with post-ERCP hepatic decompensation in patients with cirrhosis to better inform clinical decision-making and minimize adverse outcomes.

METHODS

A retrospective analysis was conducted on patients with cirrhosis undergoing ERCP. Clinical, biochemical, and procedural variables were evaluated to determine their association with hepatic decompensation. Multivariate analysis was performed to identify independent predictors.

RESULTS

A total of 277 patients with cirrhosis who underwent an ERCP were included. The cohort had a mean age of 63.4 years, with a male predominance (65.3%) and various etiologies of cirrhosis, including alcohol-related (39.3%) and hepatitis C (11.4%). Post-ERCP complications occurred in 26.7% of patients. The most common complications were hepatic decompensation events (18.4%), sepsis (10.8%), and cholangitis (6.1%). Patients with complications had significantly higher baseline MELD scores, INR, chronic kidney disease (CKD) and history of ascites, hepatic encephalopathy, and hepatorenal syndrome (HRS). A Multivariate analysis revealed that factors such as higher MELD score, ascites, hepatic encephalopathy, and stent placement were associated with post-ERCP complications. Subgroup analyses indicated that patients who developed hepatic decompensation events (ascites, SBP, or HRS) had a more severe liver dysfunction at baseline, as reflected by a higher MELD score and INR, and prior episodes of ascites and hepatic encephalopathy.

CONCLUSION

Pre-procedural liver function parameters and procedural factors are crucial predictors of post-ERCP hepatic decompensation in patients with cirrhosis. Key risk factors include higher MELD score, CKD, history of ascites, and hepatic encephalopathy. Careful pre-procedural evaluation and management are essential to reduce these risks.

Surgical versus endoscopic management of esophageal perforation

PURPOSE OF REVIEW

The management of esophageal perforation is a topic of debate, as there now are viable surgical and endoscopic options. Historically, surgical management had been considered the standard of care for these perforations, but such surgical management can be associated with considerable morbidity. In this report, we explore contemporary options for the care of patients with esophageal perforations.

RECENT FINDINGS

Innovations in endoscopic therapies, including self-expanding metal and plastic stents, over-the-scope clips, vacuum therapy, and endoscopic suturing have expanded treatment options for esophageal perforations. These approaches are particularly beneficial for selected patients with early, contained perforations, offering reduced morbidity and shorter hospital stays. However, surgical intervention remains essential in cases of extensive contamination, necrosis, or delayed diagnosis. A growing body of evidence supports a patient-specific approach, integrating both traditional and emerging interventions.

SUMMARY

The management of esophageal perforation is evolving with the increasing use of minimally invasive endoscopic techniques. However, surgical repair remains the definitive treatment in patients with hemodynamic instability or extensive contamination. Timely intervention is critical, as delayed diagnosis significantly increases morbidity and mortality. A tailored approach, incorporating patient-specific factors and nature of the disease, ensures optimal outcomes.

Sclerosing eosinophilic extrahepatic cholangitis in a cat

A 9-year-old female cat was presented to the veterinary hospital with a history of progressive weight loss, anorexia and jaundice. Clinical findings included poor body condition, hypothermia and jaundice. The ultrasound findings were consistent with cholangiohepatitis associated with pancreatitis and the biochemical tests indicated a marked increase in activities of hepatobiliary enzymes (alkaline phosphatase, alanine aminotransferase, gamma-glutamyl transpeptidase). At necropsy, the animal had marked jaundice in the mucous membranes and subcutaneous tissue and a mildly enlarged liver with diffusely orange discolouration. The cystic duct was thickened, white, firm and completely obstructed. The gallbladder was enlarged and contained thickened bile. Microscopically, the cystic duct was obliterated by severe proliferation of fibrous connective tissue and marked proliferation of bile ducts, with a prominent multifocal inflammatory cell infiltrate composed predominantly of eosinophils, lymphocytes, rare plasma cells and macrophages. Although eosinophilic cholangitis is considered benign in humans, in this case it had led to complete obstruction of the cystic duct due to wall thickening caused by eosinophilic inflammation and fibrous connective tissue proliferation, which contributed to clinical deterioration.

Extracardiac Compression by Gastrointestinal Structures: A Comprehensive Anthology From the Literature

Extrinsic heart compression by gastrointestinal (GI) structures is an often underrecognized finding in clinical practice. It is potentially related to unpredictable clinical conditions, ranging from incidental detection in asymptomatic subjects, to deranging and potentially life-threatening clinical manifestations. However, despite its potential clinical relevance, there is still no comprehensive analysis investigating the surrounding causes, clinical findings, and diagnostic imaging work-up for this patient population. A narrative review with an extensive bibliographic search of the literature was performed using PubMed (MEDLINE), Embase, and Cochrane Central Databases up to December 31, 2023. Despite the broad spectrum of GI etiologies, clinical manifestations, and cardiac chamber involvement scenarios, physicians must be aware of such an uncommon condition, in order to provide timely diagnosis through a comprehensive imaging approach, avoid misleading interpretations, and determine the most appropriate decision-making strategy.

Association of periampullary diverticulum types with post-ERCP hyperamylasemia: a retrospective observational study

BACKGROUND

This study aimed to assess the prevalence of periampullary diverticulum (PAD) among endoscopic retrograde cholangiopancreatography (ERCP) patients in Southwestern Turkey and investigate the association between the new PAD classification, post-ERCP hyperamylasemia, and post-ERCP pancreatitis (PEP).

MATERIALS AND METHODS

We retrospectively reviewed 1,317 ERCP procedures performed between January 1, 2022, and December 31, 2023, at Antalya Training and Research Hospital. The PAD type was determined according to the He-xian Shi classification. Hyperamylasemia was defined as an increase of three times the normal level of amylase at 4 to 6 h, and PEP was defined as hyperamylasemia along with abdominal pain lasting more than 24 h.

RESULTS

A total of 594 naive patients who underwent ERCP were analyzed. PAD was present in 137 patients (23.1%), and the success rate of choledochal cannulation in the first ERCP procedure was 94.3%. There was no difference in the choledochal cannulation rate between patients with and without PAD (95.6%-93.4%, p = 0.59). Asymptomatic hyperamylasemia was observed in 19.3% of the patients. Post-ERCP hyperamylasemia rates were similar between patients with and without PAD (17.5% and 21.2% respectively, p = 0.31). PEP was observed in 8.0% of the patients. Presence of PAD was not a risk factor for post-ERCP pancreatitis (7.3% compared to 8.8%, p = 0.82). When we checked the results according to the type of PAD, the prevalence of post-ERCP hyperamylasemia was significantly lower in patients with type 2b PAD than in those with type 1 and type 2a patients.

CONCLUSION

PAD is a common finding in ERCP patients, with a prevalence of 23.1% in our cohort. The rate of choledochal cannulation, post ERCP hyperamylasemia and PEP did not differ between the patients with and without PAD. However, the type of PAD is important; post-ERCP hyperamylasemia is significantly lower in patients with type 2b than in type 1 and type 2a PAD patients. Different subtypes of PAD may have different associations on ERCP outcomes. Further investigations with refined and standardized PAD classification systems are needed.

A randomized, controlled trial of oral sulfate solution versus polyethylene glycol for bowel preparation for colonoscopy

BACKGROUND

The quality of colonoscopy is significantly influenced by the effectiveness of bowel preparation. In this study, we aimed to evaluate the efficacy, safety, and tolerability of bowel cleansing between a new oral sulfate solution (OSS) and standard polyethylene glycol electrolyte powder (PEG).

METHODS

This single center, randomized, superiority study recruited 679 outpatients who were assigned to either the new OSS group (Group A) or standard PEG group (Group B). The quality of bowel cleansing was evaluated using the Boston Bowel Preparation Scale (BBPS) and compared between the two groups. Furthermore, data pertaining to the duration of bowel preparation, patient tolerability, and the occurrence of adverse events were also analyzed.

RESULTS

According to BBPS scores, group A demonstrated significantly higher bowel preparation cleanliness than group B. Additionally, group A achieved superior bowel cleansing, as evidenced by a greater proportion of patients with BBPS scores ≥ 8 compared to group B (75.3% vs. 55.2%, P < 0.05). No severe adverse events were reported during examinations in either group.

CONCLUSIONS

The magnesium sulfate, sodium sulfate, and potassium sulfate concentrated oral solution is a novel, safe, and effective bowel preparation for colonoscopy.

TRIAL REGISTRATION

This study was registered in the Chinese Clinical Trial Registry on 20/02/2024 (clinical trial registration number: ChiCTR2400081004).

Delayed endoscopic retrograde cholangiopancreatography: a game-changer for acute cholangitis patients in a resource-limited setting

Background

Acute cholangitis (AC) is a critical biliary infection caused by gallstones that can progress to systemic inflammation, sepsis, and organ failure. The 2018 Tokyo Guidelines advocate for early endoscopic retrograde cholangiopancreatography (ERCP) in moderate-to-severe AC, but its timing in resource-limited settings remains debated. In Vietnam, where healthcare resources may be limited, the timing of ERCP in patients with AC caused by gallstones has not been extensively studied.

Objectives

To compare outcomes of early ERCP (eERCP, ⩽48 h) versus delayed ERCP (dERCP, >48 h) in managing stone-induced AC.

Design

This was a retrospective cohort study analyzing outcomes of early versus dERCP in 708 patients with stone-induced AC. The study aimed to evaluate procedural efficacy, complications, and long-term outcomes, particularly in a resource-limited setting. Patients were stratified based on ERCP timing (⩽48 h for eERCP and >48 h for dERCP) to enable direct comparisons.

Methods

Data on demographics, clinical features, laboratory findings, and procedural outcomes were analyzed.

Results

The eERCP group exhibited higher rates of severe cholangitis and elevated inflammatory markers compared to the dERCP group. Intensive care unit admission rates were also higher in the eERCP group (3.1% vs 0.8%, p = 0.02). Perforation complications occurred more frequently in the dERCP group (1.2% vs 0%, p = 0.01), while stone treatment outcomes were comparable between the two groups. The eERCP group had a shorter hospital stay (6.5 vs 9.3 days, p < 0.05), although there were no significant differences in readmission or 1-year mortality rates. For patients with severe cholangitis, the treatment outcomes for stones, complications after intervention, and the 1-year mortality and readmission rates are similar between the two groups.

Conclusion

In resource-limited settings, dERCP following resuscitation provides outcomes comparable to eERCP, offering a viable alternative when resources are constrained.

Remimazolam alleviates hepatic ischemia-reperfusion injury by activating FOXO1/3 signaling : Remimazolam alleviates hepatic ischemia reperfusion injury

BACKGROUND

Hepatic ischemia reperfusion injury (HIRI) frequently gives rise to aggravated liver damage. Currently, there exists a diverse range of anesthetic drugs that possess protective capabilities against ischemia-reperfusion injury (IRI). Nevertheless, the specific functions and underlying mechanisms of remimazolam (RMZL) in HIRI have not been fully elucidated.

METHODS

HIRI models of both hepatocytes and mice were successfully established. To evaluate liver function and injury, ELISA, HE and TUNEL staining were employed. The levels of oxidative stress markers and inflammatory factors were measured using commercial kits. Cell viability and apoptosis were measured by CCK-8 and flow cytometry, respectively. The abundance of genes and proteins was determined utilizing RT-qPCR and western blot.

RESULTS

It was observed that RMZL administration greatly alleviated liver damage and repressed oxidative stress and inflammation in HIRI mouse models. In vitro experiments demonstrated that RMZL strongly protected LO2 cells from H/R-induced cell damage, oxidative stress, and inflammatory responses. Moreover, FOXO1 and FOXO3, which function as classic cell protection and anti-oxidative stress factors, were observed to be downregulated in liver tissue from HIRI mouse models and H/R-challenged LO2 cells. Notably, this downregulation could be reversed by the administration of RMZL. Furthermore, FOXO1 or FOXO3 knockdown abolished the protective effects of RMZL, including promoted cell survival and inhibited oxidative stress and inflammation in LO2 cells upon H/R exposure.

CONCLUSION

These data provided robust support for the notion that RMZL attenuated oxidative stress and inflammation to alleviate HIRI through enhancing FOXO1 and FOXO3 expressions, suggesting that RMZL holds great promise as a potential candidate anesthetic for HIRI treatment.

Endoscopic Ultrasound-guided Tissue Acquisition of Pancreatic Malignancy: A Retrospective Study at a Tertiary Center

BACKGROUND

Endoscopic ultrasound (EUS) is gaining ground in today's diagnostic routine due to its ability to provide dynamic, accurate representations, but mostly because it facilitates tissue sampling amenable to histopathologic studies. Our main objective was to assess the accuracy of sampling pancreatic malignancies through EUS-fine-needle aspiration (FNA) compared to EUS-fine-needle biopsy (FNB) at a tertiary referral center, where rapid on-site evaluation (ROSE) for EUS-FNA is not available.

MATERIAL AND METHODS

A retrospective, 5-year analysis of all EUS-guided tissue acquisitions of pancreatic masses suggestive of neoplasia was performed. Out of the 484 patients who initially underwent non-invasive imaging studies, 401 subjects were ultimately confirmed as malignant using EUS-FNA/FNB or surgery.

RESULTS

Overall, the accuracy of EUS-guided sampling was 91%. There were 36 patients (9%) with false-negative results after EUS, who were further addressed to surgery and confirmed with pancreatic malignancy. Cytological and histological examinations found that FNB was significantly higher than FNA regarding the diagnostic yield (91.3% vs. 84.1%; p-value<0.05). Moreover, FNB required fewer needle punctures than FNA to achieve a definitive diagnosis (1.63 vs. 1.99; p-value<0.05).

CONCLUSIONS

Diagnostic management of pancreatic malignancies is unequivocally improved by FNB needles, rendering an improved tissue acquisition at a lower number of passes.

The Prediagnostic General Practitioners' Pathway of Gastrointestinal Stromal Tumor Patients: A Real-World Data Study

Background/Objectives: Gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors of the gastrointestinal (GI) tract, predominantly driven by KIT or PDGFRα oncogene mutations. Nonspecific symptoms contribute to diagnostic delays, with general practitioners (GPs) playing a pivotal role in early detection. However, studies on GIST-specific primary care pathways are limited. This study examines GP contacts, diagnoses, and prescribed drugs in primary care during the 12 months preceding GIST diagnosis. Methods: This case-control study utilized data from the Netherlands Cancer Registry and Nivel Primary Care Database. It included 294 GIST patients diagnosed between 2010 and 2020 and 576 matched cancer-free controls. GP contacts, diagnoses, and newly prescribed drugs were analyzed across two time intervals: 0-4 and 5-12 months prediagnosis. Statistical comparisons were conducted using the Wilcoxon rank-sum test and descriptive analyses. Results: GIST cases had a median of six GP contacts (IQR 4-11) in the 12 months prediagnosis versus three (IQR 2-6) for controls (p < 0.05). Contacts increased 4 months before diagnosis, peaking 1 month prior. Common diagnoses in the 4-month interval included malignant neoplasms of the stomach (27.9%) and other digestive sites (27.6% and 11.2%), abdominal pain (9.5%), and iron deficiency anemia (9.5%). Newly prescribed drugs included proton pump inhibitors (13.9%) and osmotically acting laxatives (15.0%). Conclusions: This study highlights increased GP visits and specific reasons for these visits before GIST diagnosis. Future research should further examine GP records, not only through coded data but also unstructured data, and incorporate patient and GP perspectives to explore potential improvements in the diagnostic process.

A review on pancreatic duct stents: materials and emerging trends

Pancreatic duct strictures, which can arise from trauma, inflammation, or malignancy, often result in complications such as duct obstruction, pancreatic parenchymal hypertension, and ischemia. Endoscopic stenting is an effective therapeutic approach for managing these strictures. However, traditional plastic pancreatic duct stents fail to conform to the physiological curvature of the pancreas, while metal pancreatic duct stents with flared ends reduce migration but are associated with complications such as de novo strictures. Additionally, plastic and metal pancreatic duct stents require surgical removal. Whereas biodegradable pancreatic duct stents present a promising alternative due to their superior biocompatibility and ability to decompose into non-toxic materials, potentially eliminating the need for additional surgeries. Despite these advantages, biodegradable pancreatic duct stents remain in the experiment stage. This review assesses current materials of pancreatic duct stents, and emphasizes recent advancements in biodegradable options and emerging trends in clinical applications.

Severe Rectal Stenosis as the First Clinical Appearance of a Metastasis Originating from the Bladder: A Case Report and Literature Review

While locally advanced rectal cancer is the first clinical suspicion for severe rectal stenosis, in extremely unusual cases a lower bowel obstruction may be related to bladder metastasis. We present the case of a 64-year-old male who was admitted for occlusive rectal tumor (4 cm from the anal verge), for which an emergency loop-colostomy was performed. After two inconclusive endoscopic biopsies, a transanal rectal tru-cut biopsy allowed for the detection of high-grade urothelial carcinoma with signet ring cells. Furthermore, primary origin was detected in a small bladder tumor. In imaging reassessment after neoadjuvant chemotherapy, regression of the lesions both from the bladder and rectum was observed. Radical surgery with total pelvic exenteration was considered in the absence of other secondary tumors, but the patient declined and continued with radiotherapy. Subsequently he developed malignant chylous ascites and unfortunately died three months later. Reviewing the literature, we found twenty-five cases of urothelial metastasis to the rectum, originating from the bladder, including this newly present case. Rectal metastasis of urothelial origin poses a two-fold challenge in terms of both diagnosis and treatment. Determining the specific features of this uncommon manifestation of a common disease will improve future approaches.

Efficacy and Safety of Percutaneous Transhepatic Lithotripsy Using SpyGlassDSTM Cholangioscopy for the Treatment of Difficult Stones

Background/Objectives: the aim of this study was to evaluate the safety and efficacy of percutaneous transhepatic lithotripsy using the SpyGlassDSTM cholangioscopy system for the treatment of difficult stones. Methods: Retrospectively, all patients treated with percutaneous transhepatic lithotripsy using SpyGlassDSTM cholangioscopy system were analyzed. As primary outcome measures, the following data were assessed: the presence of a previous history of the hepatobiliary disease, location of stones, reasons for the choice of the procedure, previous balloon bilioplasty, type of pre-procedural imaging, procedural time, technical success, clinical success, and post-procedural complications (according to CIRSE classification). Clinical success was considered "primary" when achieved with a single treatment, and "secondary" if more than one treatment was required in the duration of follow-up. Results: 10 patients (6 males and 4 females, mean age = 64 years, SD = 22), all with cholangitis due to gallstones, underwent 11 PTL procedures using SpyGlassDSTM. Technical and clinical successes were achieved in all patients (100%). Primary success was observed in 4/10 (40%) patients, while the remaining 6/10 (60%) patients undergoing re-treatment, and all showed secondary success (100%). No periprocedural complications were observed. In 10/11 procedures (90%), no relevant adverse events were recorded within the first thirty days of follow-up. In 1/11 case (9%), mild complications (grade I according to CIRSE classification) were registered in the following days after the procedure (<30 days). Conclusions: in conclusion, the treatment of percutaneous transhepatic lithotripsy using SpyGlassDSTM cholangioscopy of difficult stones has been demonstrated as efficient and safe treatment.

Transanal endoscopic microsurgery in the treatment of rectal neuroendocrine tumors: a retrospective 10-year single-center experience

PURPOSE

Transanal endoscopic surgery is a recommended full-thickness resection technique for the treatment of rectal neuroendocrine tumors. We aimed to compare the efficacy, safety and follow-up of patients with rectal neuroendocrine tumors treated with transanal endoscopic microsurgery in the primary setting and as salvage therapy after non-radical endoscopic polypectomy.

METHODS

A retrospective analysis of a 10-year database of patients treated with transanal endoscopic microsurgery was performed. The procedure-related measures, including duration of the procedure, adverse events, and patient-related measures, including age, gender, tumor size, grading, and length of follow-up, were obtained. We compared the primary TEM group with the salvage group.

RESULTS

In total, 30 patients with rectal neuroendocrine tumors were included in the study; 13 of them received primary treatment and 17 salvage therapy of the scar. Patients receiving primary treatment were significantly older (60.5 vs. 51.7 years). There were no significant differences in patient gender, tumor size and grading, length of follow-up, hospital stay or procedure time. The R0 resection rate was 92.3% in the primary treatment group. Adverse events were mild or managed with endoscopic treatment. Follow-up was slightly but not significantly longer in the primary treatment group and showed no recurrences in both groups of patients.

CONCLUSIONS

Transanal endoscopic microsurgery is safe and effective for both primary and salvage treatment of rectal neuroendocrine tumors.

Transcatheter arterial embolization for acute nonvariceal upper Gastrointestinal bleeding in children: a single-center retrospective study

OBJECTIVE

This study aims to provide a preliminary report on the outcomes of transcatheter arterial embolization (TAE) in pediatric patients with acute nonvariceal upper gastrointestinal bleeding (NVUGIB) to establish optimal practices for this intervention and explore its potential value in improving the management of pediatric patients.

METHODS

A retrospective analysis was conducted on children with NVUGIB who underwent TAE at a single institutional center between February 2022 and April 2024. Comprehensive data were collected, including patient demographics, clinical manifestations, diagnostic and therapeutic procedures, intraoperative findings, and follow-up outcomes.

RESULTS

A total of 266 cases with NVUGIB were admitted to the institutional center, with 14 cases (5.26%) undergoing TAE. There were 10 males and 4 females. The average age was 7.21 ± 4.77 years old, and the average hospital stay was 13.14 ± 8.69 days. Nine cases (64.29%) had hematochezia, 2 cases (14.29%) had hematemesis, 3 cases (21.42%) had both hematochezia and hematemesis. Six cases (42.86%) had no significant medical history, 3 cases (21.42%) had previous Helicobacter pylori infections, 2 cases (14.29%) had previous lymphomas, and 1 case (7.14%) each had immune disorders, gastroenteritis, and fever. The mean preoperative minimum hemoglobin level was 57.85 ± 21.25 g/L. All cases underwent gastroenteroscopy before TAE. Ten cases (71.43%) had duodenal bulb ulcers, 3 cases (21.43%) had duodenal ulcers, and 1 case (7.14%) had multiple ulcers in the gastric antrum. Bleeding was visible on endoscopy in 6 cases (Forrest Classification Ib,42.86%) (Table 2; Fig. 2), which were treated. All cases underwent TAE, and the timing of TAE averaged 4.29 ± 4.53 days. The responsible vessel was identified intraoperatively in all cases: gastroduodenal artery in 7 cases (50%) and pancreaticoduodenal artery in 7 cases (50%). A pseudoaneurysm was found in 2 cases (14.29%). Embolization of the responsible vessel was performed in all cases, using platinum coils alone in 8 cases (57.14%) and platinum coils combined with gelatin sponge in 6 cases (42.8%). All cases were followed up for an average of 13.69 ± 8.77 months, and no recurrence was detected.

CONCLUSION

TAE represents a promising intervention for pediatric patients with acute NVUGIB. Nevertheless, optimal timing, embolization techniques, and selection of embolizing agents necessitate further comprehensive investigation.

Weight Recidivism After Bariatric Surgery: A Narrative Review

Bariatric surgery, while effective for severe obesity, is often challenged by postoperative weight regain (WR), affecting 20-30% of patients. This review analyzes the mechanisms, risk factors, and management strategies for WR, emphasizing surgical considerations. WR is influenced by hormonal adaptations, including ghrelin rebound and leptin resistance, as well as metabolic adaptation, leading to reduced resting energy expenditure. Surgical factors, such as suboptimal technique, gastro-gastric fistulas, and stomach/anastomosis dilation, significantly contribute to WR. Specifically, inaccurate sleeve or pouch sizing, poorly calibrated anastomoses, and complications with gastric banding necessitate careful surgical planning and potential revision. Management strategies encompass lifestyle interventions (diet, exercise, behavioral therapy), pharmacotherapy (GLP-1 receptor agonists like liraglutide, semaglutide, and tirzepatide), and revisional surgery. Revisional procedures, including sleeve-to-bypass, bypass revision, sleeve-to-duodenal switch/SADI, and band removal with conversion to sleeve or bypass, address anatomical failures and enhance weight loss. Distinguishing surgical failure from patient nonadherence is crucial for appropriate intervention. Ultimately, a collaborative, multidisciplinary approach integrating these strategies optimizes long-term weight management and improves patient outcomes after bariatric surgery.

Young, Healthy, Underweight Women Require Higher Effective Doses of Propofol for Successful Gastroscope Insertion: a Dose-Finding Study Using Dixon's Up-and-Down Method

Purpose

The number of young women undergoing painless gastroscopy is rising annually. However, the lack of studies on the effective doses of propofol sedation for young, underweight women, presents a clinical challenge. Our study aimed to determine and compare the effective doses of propofol required for successful gastroscope insertion in normal-weight and underweight young women.

Patients and Methods

Chinese women aged 18-35 years who were of normal weight (18.5 ≤ body mass index (BMI) < 25 kg/m²) or underweight (BMI < 18.5 kg/m²) and were undergoing painless gastroscopy were included. The initial induction dose of propofol was 2.0 mg/kg, and subsequent doses were adjusted using the modified Dixon's up-and-down method (step size: 0.1 mg/kg). The 50% and 95% effective dose of propofol (ED50 and ED95), defined as the doses required for successful gastroscope insertion in 50% and 95% of patients, respectively, were determined using the modified Dixon's up-and-down method and isotonic regression analysis. All adverse events were documented.

Results

Thirty patients were included in each group. The modified Dixon's up-and-down method was used, and the ED50 of propofol was found to be significantly higher in patients in the underweight group (2.72 ± 0.23 mg/kg) than those in the normal-weight group (2.03 ± 0.13 mg/kg) (P < 0.001). The ED50 and ED95 in the normal-weight group extrapolated using isotonic regression analysis were 2.00 (83% confidence interval [CI], 1.900-2.100) mg/kg and 2.30 (83% CI, 2.300-2.400) mg/kg, respectively. In the underweight group, these values increased to 2.80 (83% CI, 2.700-2.900) mg/kg and 3.00 (83% CI, 3.000-3.100) mg/kg, respectively. The nonoverlapping CIs indicated significant differences between patients in the normal-weight and underweight groups.

Conclusion

Young, healthy, underweight women require higher effective doses of propofol for deep sedation for successful gastroscope insertion compared with young, healthy, normal-weight women.

Leucine-Rich Alpha-2 Glycoprotein 1 as a Biomarker for Evaluation of Inflammatory Bowel Disease Activity in Children

Background: Leucine rich α-2 glycoprotein (LRG) is a glycoprotein that is an acute-phase protein produced by neutrophils, macrophages, hepatocytes, and intestinal epithelial cells. This study aimed to determine the serum LRG (s-LRG) and urine LRG (u-LRG) expression levels in children with inflammatory bowel disease (IBD) and evaluated their correlation with clinical disease activity, other inflammatory markers, laboratory results, and endoscopic activity scoring. Methods: This prospective observational study was conducted at a tertiary centre and included children aged 2-18 years with IBD. Clinic activity scoring was used to assess clinical disease activity. Haemoglobin levels, platelet counts, albumin, C-reactive protein, and erythrocyte sedimentation rate were analysed in the blood sample. LRG levels were measured in both blood and urine samples. The endoscopic assessment was scored according to the simple endoscopic score and Mayo endoscopic score. Serum and urine LRG levels were measured using commercial enzyme-linked immunosorbent assay kits. Disease activation was defined based on clinical activity scoring, laboratory results, and endoscopic evaluation. The results were compared between the active IBD and remission groups. Results: Forty-two (50%) patients with active IBD and forty-two (50%) patients in remission were included in this study. The serum levels of LRG were elevated in the patients with active IBD compared with the levels in the patients with IBD in remission (p = 0.020). However, there was no difference in the u-LRG level between the two groups (p = 0.407). In patients with IBD, positive correlations were observed between s-LRG, platelet count, C-reactive protein (CRP), and the erythrocyte sedimentation rate. The serum LRG was negatively correlated with albumin and haemoglobin levels. Urine LRG was not correlated with s-LRG in any patients with IBD included or in patients with active IBD. The cutoff value for s- LRG (77.03 μg/mL) had a sensitivity and specificity of 40.4% (95% CI 25.6-56.7%) and 88.1% (95% CI 74.3-96.0%), respectively. It was found that s-LRG was a more significant parameter than CRP in predicting disease activation. Conclusions: This prospective study demonstrated that the s-LRG level is a useful biomarker for predicting disease activation in children with IBD and appears to be a more significant parameter than the CRP level. However, the u-LRG level is not effective in predicting disease activation in children with IBD.

Spanish Working Group in Crohn's Disease and Ulcerative Colitis (GETECCU) position paper for the management of non-perianal fistulizing Crohn's disease

Crohn's disease consists on a complex condition where, despite most patients initially present with an inflammatory behavior, a significant proportion develop complicated lesions such as strictures, fistulas, abscesses, or even perforations. These lesions progressively increase over time and are associated with a higher risk of surgery and hospitalization. Despite significant advances in their management after the introduction of biological therapies, particularly anti-TNF agents, these complications continue to pose challenges for the multiple professionals involved in their care. Fistulas that do not involve the perianal region (entero-enteric, entero-urinary, or entero-cutaneous) require a multidisciplinary strategy that combines medical, interventional, and surgical approaches. Their treatment ranges from general supportive measures to the use of antibiotics or, frequently, advanced therapies. Nevertheless, in cases of certain septic complications or those refractory to medical treatment, percutaneous drainage or surgical intervention remains essential. Although these lesions have a significant impact, evidence regarding the best strategies in this context, as well as the efficacy and safety of different therapies in these patients, remains limited. This is highlighted by the absence of specific recommendations in current guidelines. The objective of this document is to provide a comprehensive overview of non-perianal fistulizing Crohn's disease, addressing its epidemiological, clinical, and therapeutic aspects from a multidisciplinary perspective.

Intricacy of Crohn's disease: Incongruity between diagnostic modalities and histopathologic assessment

Crohn's disease (CD) is a chronic and recurrent inflammatory condition. Histologic healing is associated with better outcomes in CD, while less is known regarding the assessment of histological condition. Recently, a study has examined the discordance between endoscopic and histopathologic assessment in ileal CD, revealing a poor correlation between endoscopic and histologic evaluations in assessing mucosal inflammation and disease activity. However, the involvement of CD can span the entire gastrointestinal tract, as well as numerous clinical manifestations and extraintestinal complications, and the patchy nature of transmural inflammation is a well-established characteristic of this disease. The diagnosis of CD relies on a comprehensive evaluation that includes clinical, biochemical, stool, endoscopic, cross-sectional imaging, and histological investigations due to the incomplete understanding of its etiology and pathogenesis. Upon diagnosis, complimentary investigations should focus on markers of disease activity. Since transmural inflammation can only be assessed in resections, therefore, we primarily focused on the evaluation value of clinical aspects, histological scoring systems, particular in vivo imaging evaluation such as computed tomography enterography, magnetic resonance elastography, scintigraphy, sonographically measurement, endoscopic ultrasonography, and advanced endoscopic imaging techniques.

Endoscopic intervention in hematologic malignancy patients with severe thrombocytopenia: Methodological concerns, clinical implications, and future research directions

Gastrointestinal bleeding (GIB) presents a significant challenge for patients with hematologic malignancies, especially those with severe thrombocytopenia. Although endoscopic intervention is frequently used in managing GIB, its safety and effectiveness in this high-risk group remain unclear. A recent study by Alhumayyd et al provided insight into this issue. However, it has notable limitations, including its retrospective nature, small sample size, and failure to adjust for important confounding factors such as disease severity, hemodynamic status, and platelet function. The study's findings indicated that urgent endoscopy may help decrease the incidence of recurrent bleeding; however, it did not show a clear benefit in terms of mortality. Future research ought to prioritize prospective, multicenter studies that employ standardized protocols and incorporate risk stratification models to better understand the impact of endoscopic treatment for GIB in these patients. Additionally, integrating platelet function assays could improve clinical decision-making. Addressing these research gaps is essential for improving patient outcomes and developing effective guidelines for managing GIB in individuals with thrombocytopenia.

Leucine-rich alpha-2 glycoprotein for detecting small bowel lesions in Crohn's disease: A critical review and the path forward

The study by Ohno et al provides valuable insights into the role of leucine-rich alpha-2-glycoprotein (LRG) as a potential biomarker for identifying small bowel lesions in Crohn's disease (CD). However, several methodological challenges hinder its immediate use in clinical practice. Notably, the current research was retrospective, lacks comparative studies with fecal calprotectin, and did not provide long-term predictive data. Further prospective studies are needed to improve the applicability of LRG. Moreover, integrating LRG with additional biomarkers and employing artificial intelligence techniques may improve its effectiveness in disease monitoring. Future research should address interobserver variability, assess LRG's cost-effectiveness, and standardize endoscopic healing definitions to ensure broader applicability. Advancing these areas is vital for establishing LRG's role in precision medicine strategies for the management of CD.

What is the benefit of endoscopic ultrasound-guided gastrojejunal anastomosis for patients with benign gastric outlet obstruction? A systematic review with meta-analysis

BACKGROUND

Gastric outlet obstruction for benign indications (bGOO) is an uncommon condition, typically treated with surgery when medical therapy or endoscopic treatments fail. At present, endoscopic ultrasound (EUS)-guided gastrojejunostomy (GJ) may prove to be an effective alternative.

AIMS

We performed a systematic review with meta-analysis evaluating outcomes of EUS-GJ for bGOO.

METHODS

A comprehensive search was conducted up to February 2025. Pooled estimates were obtained using a random-effects model. Study quality was evaluated using the Newcastle-Ottawa quality scale. Heterogeneity was evaluated with I2 statistic. Technical success, clinical success, recurrence rate, and adverse events (AE) rate were the main outcomes.

RESULTS

Fifteen (15) studies, including a total of 376 patients, were identified. Pooled technical success was 95.8 % (CI 95 %, 93.8 %-97.8 %, I2 =0 %), while clinical success was 93.4 % (CI 95 %, 90.4 %-96.5 %, I2= 31.83 %). Pooled recurrence rate was 11.6 % (CI 95 %, 5.5 %-17.7 %, I2=32.36 %). The pooled rate of AE was 11.6 % (CI 95 %, 6.8-16.5 %, I2 = 57.18 %). Subgroup analyses found differences in safety when AE classification was used (17 % use vs. 6 % no use, p = 0.02) and based on quality of studies (low 22 % vs. moderate 10 % vs. high 3 %, p = 0.04).

CONCLUSION

In conclusion, our findings show that EUS-GJ is effective and safe in those patients with bGOO in whom other endoscopic treatments fail, and surgery is not an option or could be performed as bridge-to-surgery. Our results suggest that safety is influenced by the use of AE classification and the quality of studies.

Assessing endoscopic remission in small bowel Crohn's disease: Are markers enough?

Mucosal healing in Crohn's disease (CD) has been established as a crucial target of treatment, leading to long term remission and decrease in complication rates. Endoscopy still serves as the gold standard for assessment, particularly in the small bowel where balloon or capsule enteroscopy is frequently needed. However, these modalities are often unavailable, expensive, and invasive, posing risks to patients. Consequently, the identification of accessible and reliable biomarkers, especially in small intestinal CD, remains a challenge. The study by Ohno et al, published in this issue, further illuminates this field. It confirms the potential role of fecal biomarker leucine-rich α2 glycoprotein (LRG) and validates findings from previous smaller trials. Comparing to other markers LRG showed a much higher predictive value for mucosal healing of the small bowel, making it a useful option for small intestinal CD follow up. In this editorial, we explore the optimal marker of inflammation or mucosal healing in CD, particularly in the small bowel. We provide an overview of available conventional biomarkers and introduce several novel biomarkers, including an update on emerging technologies and innovations.
