Eosinophilic esophagitis (EoE) is a chronic, allergic, immune-mediated inflammation of the esophagus caused by food antigens. The prevalence in pediatric population is approximately 34 to 57 cases per 100,000 children, with a male to female ration 3:1. This number may be underestimated due to diagnostic challenges and variety of clinical presentations in different age groups. Diagnosis of EoE requires histopathological assessment of esophageal biopsies retrieved during gastroscopy, with at least 15 eosinophils per high-power field (HPF) in the esophageal tissue being the cut off value. According to recommendations, treatment options of EoE include dietary interventions (elimination diets), medical treatment (inhibitors of proton pump, steroids, biologics), and in some cases surgical intervention (dilation). Dietary intervention, such as elimination diets, target the triggering factors of the disease and, if supervised by professional nutritionist, have the least systemic side effects. On the other hand, depending on the number of allergens eliminated from the pediatric patients’ diet, the quality of life both of the child and their caretakers may be compromised. Additional challenges such as nutritional risks, feeding disorders, financial burden, and social life impairment also have to be taken into consideration. On top of this, an effectiveness assessment of chosen therapy requires repeated endoscopic examination with several biopsies of the esophagus, further increasing diseases burden in EoE patients. Taking all of this factors into consideration, the main objective of this narrative review was to address challenges that pediatric patients with EoE on dietary treatment face with reference to current research and daily practice.

Background: Lichen planus (LP) is a common inflammatory disease affecting skin, mucous membranes, hairs, and nails, with an unpredictable course involving remissions and relapses. LP is a Type-I-Inflammation disease involving IFN-γ and IL-17 as key inflammatory mediators. Materials and Methods: We searched PubMed/MEDLINE and Google Scholar search engines for studies on the esophageal manifestation of lichen planus over an unlimited time frame. Articles were searched with combinations of Medical Subject Heading (MeSH) terms. Given the limited number of publications, no exclusion criteria were applied. Results: Esophageal lichen planus (ELP) is an underreported manifestation of LP that primarily affects middle-aged women. Its prevalence among LP patients remains to be defined. Though potentially clinically silent, ELP can significantly impact patient wellbeing and serve as a precursor to esophageal squamous cell carcinoma. While dysphagia is the primary symptom, the condition may also remain subclinical. The endoscopic hallmarks of ELP are mucosal denudation and tearing, trachealization, and hyperkeratosis. Chronic disease progression may lead to scarring esophageal stenosis. Histologically, ELP shows mucosal detachment, T-lymphocytic infiltrations, epithelial cell apoptosis (Civatte bodies), dyskeratosis, and hyperkeratosis. Fibrinogen deposits along the basement membrane zone distinguish ELP from various immunological esophageal diseases. There is currently no standardized therapy available. Topical steroids lead to symptomatic and histologic improvements in two-thirds of patients. Severe or refractory cases require immunosuppressive therapy, whereas JAK-inhibitors represent a promising emerging option. Endoscopic dilation helps symptomatic stenosis. Considering ELP’s precancerous potential, timely diagnosis and treatment are crucial in preventing complications, such as stenosis or invasive esophageal squamous cell carcinoma. Conclusions: ELP is an underdiagnosed and underreported manifestation of LP. While it may remain clinically silent, it can nevertheless significantly affect patients’ wellbeing and life expectancy. This narrative review aims to initiate multidisciplinary cooperation among gastroenterologists, dermatologists, oral health professionals, and histopathologists to support clinical diagnosis and management.

Background/Objectives: Complex cases in pediatric surgery involving multiple congenital anomalies pose significant diagnostic and therapeutic challenges. These conditions require coordinated interdisciplinary care tailored to the individual patient. We present a case of syndromic congenital anomalies in a neonate, later diagnosed with CHARGE syndrome, to illustrate the importance of staged, multidisciplinary management. Methods: A 34-year-old woman in her third pregnancy developed significant polyhydramnios at 31 weeks of gestation, followed by preterm labor. The neonate presented with esophageal atresia with tracheoesophageal fistula (EA/TEF), intrathoracic stomach, aortic coarctation, patent ductus arteriosus, atrial septal defect, and bilateral choanal atresia. A structured treatment protocol was developed and implemented at Klinikum Stuttgart by an interdisciplinary team comprising gynecology, pediatric surgery, cardiology, ENT, neonatology, and genetics. Results: Initial pediatric surgical procedures included ligation of the tracheoesophageal fistula, repositioning of the intrathoracic stomach, and primary esophageal anastomosis. Cardiovascular anomalies were managed through staged interventions. Bilateral choanal atresia was surgically corrected. Genetic testing confirmed CHARGE syndrome. Postoperative care included respiratory support, enteral nutrition, and regular esophageal dilations. Due to persistent reflux esophagitis, antireflux surgery is planned. Conclusions: This case underscores the importance of a highly individualized and interdisciplinary approach in the management of syndromic congenital anomalies. The presence of CHARGE syndrome with multiple system involvement required careful staging of surgical interventions and long-term coordination of follow-up care. Early genetic diagnosis and integrated team planning were critical in optimizing outcomes in this complex neonatal case. Full article

Background/Objectives: Pneumatic dilation (PD) is a widely used treatment modality in the management of achalasia. It is particularly relevant in regions where many centers lack access to advanced therapeutic modalities. Therefore, we aimed to assess the effectiveness and safety of PD in our local region. Methods: This study retrospectively analyzed patients with achalasia that underwent PD from 1/2013 to 12/2019. The diagnosis of achalasia was established on the grounds of clinical symptoms, radiological and endoscopic findings, and esophageal manometry. Data on patient’s clinical characteristics, dilation technique and postprocedural follow-up were collected and statistically analyzed. Procedure effectiveness was defined as the postprocedural Eckardt score ≤ 3. Results: PD significantly reduced frequency of dysphagia, regurgitation, and retrosternal pain (p < 0.001). Body-weight increased significantly one month and one year after the procedure (p < 0.001). The procedural success rate was 100%. No severe complications were reported. Conclusions: PD is an effective and safe treatment modality in the management of achalasia. The study limitations include a single center design with the small number of participants, not all of whom underwent manometry, gender disproportion, absence of non-responders, and a short follow-up.

Eosinophilic esophagitis (EoE) is a chronic, immune-mediated disease characterized by esophageal eosinophilic infiltration, leading to symptoms such as dysphagia and food impaction. Endoscopy is central to both diagnosis and management, allowing for the direct visualization of characteristic features, biopsy collection, and therapeutic interventions. Despite its diagnostic value, up to one-third of patients may present with a normal-appearing esophagus, highlighting the importance of standardized scoring systems and a systematic biopsy approach. This review explores the evolving role of endoscopy in EoE, from traditional diagnostic methods to emerging technologies such as EndoFlip™ for assessing esophageal distensibility, transnasal endoscopy for non-sedated monitoring, and novel dilation techniques for fibrostenotic disease. Additionally, non-invasive biomarkers and minimally invasive tools are reshaping disease monitoring. By integrating endoscopic, histologic, and molecular approaches, future advancements may enhance diagnostic accuracy and optimize personalized treatment strategies for EoE. Full article

Esophageal fibrotic remodeling is a major complication of chronic inflammation in eosinophilic esophagitis (EoE) and represents one of the main determinants of symptoms in adult patients with EoE, with a remarkable impact on patients’ quality of life and the healthcare system. Esophageal fibrotic remodeling is diagnosed through upper gastrointestinal endoscopy, radiological studies, and a functional luminal imaging probe. However, diagnostic underestimation of esophageal strictures and suboptimal adherence to EoE guidelines still represent limitations of current clinical practice. Combined with medical therapy and/or elimination diets, endoscopic dilation remains the cornerstone treatment for esophageal strictures and rings, offering a safe and effective option for managing obstructive symptoms. Different modalities are available for esophageal endoscopic dilation of EoE, including mechanical and balloon dilators. Mechanical dilators provide tactile feedback during the procedure and exert longitudinal and radial forces. In contrast, balloon dilators apply a purely radial force and enable direct visualization of the esophageal mucosa during the procedure. Both mechanical and balloon dilators are safe and effective, with no single modality demonstrating clear superiority. Consequently, the choice of dilation technique is guided by stricture characteristics, the expertise of the endoscopist, and considerations related to the financial and environmental sustainability of the devices. This review aims to summarize the most relevant evidence on the endoscopic evaluation and dilation of fibrostenotic complications in EoE, also providing practical guidance for clinicians to optimize the endoscopic management of these patients.

Introduction: Congenital duodenal atresia (DA) (Type I) with a fenestrated web can be characterized by a late presentation with a delayed diagnosis. It is even rarer and usually associated with proximal duodenomegaly. Conventional management involves web resection and duodeno–duodeno anastomosis with or without duodenoplasty. We describe our mininvasive surgical strategy and management, detailing the aspects of laparoscopic techniques. Material and Methods: We retrospectively reviewed the medical records of five patients affected by fenestrated duodenal web (DA) with a delayed onset of symptoms and diagnosis who were managed in our Department over a period of 10 years (2013–2023). We analyzed the age of patients at diagnosis, clinical signs and symptoms, associated congenital anomalies, radiological and intraoperative findings, surgical treatment, and outcomes. Diagnostic examinations included ultrasound (US), Upper-Gastrointestinal Study (UGI), and Esophagogastroduodenoscopy (EGDS). Results: Three boys and two girls, median age of 5.5 months (range 3–11 months), were included in this study. Three underwent previous surgery for long-gap esophageal atresia (EA), two of Type A, and one of Type C, requiring a gastrostomy immediately after birth (delayed esophageal repair for prematurity in Type C) and subsequent delayed primary anastomosis. Major associated anomalies were EA (3), anterior ectopic anus (1), cloaca (1), and Type IV laryngeal web (1). An antenatal diagnostic suspicion of duodenal atresia (obstruction) on ultrasound was described in two patients. UGI suggested a fenestrated duodenal web, visualized at ultrasound in two patients. Duodenal dilation was associated in two cases. The symptoms were feeding difficulties, nonbilious vomiting, upper abdominal distension, and poor growth. All presented with a pre-ampullary obstruction. Endoscopic confirmation was only possible in one patient. The older patient underwent an endoscopic resection of a duodenal web. In the other four, we performed a laparoscopic longitudinal antimesenteric duodenal incision, web resection (excision), and transverse suture (closure was performed) without duodenoplasty. Intraduodenal Indocyanine Green (ICG) visualization (under near-infrared light) was used in the last two cases. No postoperative complications were recorded, with a mean hospital stay of 8 days. A contrast study performed at 4 weeks demonstrated an improved proximal duodenal profile; patients tolerated a full diet and remained symptom-free. Conclusions: According to our experience with minimally invasive techniques, laparoscopy and endoscopy are effective and safe, supporting web resection for the management of a duodenal web without tapering of the proximal duodenum. They require advanced technical skills. Intraduodenal-ICG injection during laparoscopic treatment of Type 1 DA allows localization of the duodenal web, confirmation of bowel patency (bowel canalization) and the tightness of suture.

Background/Objectives: Endoscopy plays a well know role in managing patients treated for esophageal atresia (EA), allowing the detection and treatment of complications such as anastomotic strictures, gastroesophageal reflux disease, and other structural abnormalities, during the critical first year of life. Nevertheless, we would like to underline the importance of endoscopy early in the follow-up of patients treated for EA, as recommended by guidelines. This study evaluates the role of endoscopy in managing patients treated for esophageal atresia (EA), focusing on the detection and treatment of complications such as anastomotic strictures, gastroesophageal reflux disease, and other structural abnormalities during the critical first year of life. Methods: A retrospective analysis was conducted over 20 years at our institution. Clinical assessments were performed at 3, 6, and 9 months to monitor growth, feeding tolerance, and proton pump inhibitor (PPI) adjustments. Endoscopic evaluations were conducted under general anesthesia around one year of age. Results: Between 2003 and 2023, 84 patients underwent surgical treatment for EA, with complete follow-up data available for 77 patients. Complications occurred in 21 patients (27%), including 4 patients (5.5%) with isolated anastomotic stricture, 8 patients (10%) with reflux esophagitis, 8 patients (10%) affected by both stenosis and reflux, and 1 case (1.5%) of fistula recurrence. Endoscopic dilatations for stenosis were successful, averaging three procedures per patient. Growth parameters were normal in 91% of cases by the first year. Conclusions: Esophagogastroscopy is a safe and effective tool for diagnosing and managing complications after EA repair in infants. The minimally invasive procedure could allow early detection of esophagitis and strictures, offering significant therapeutic benefits. Given these important results, we would like to recommend its use in routine follow-up care. Full article

Background: Over the last two decades, therapy for benign esophageal strictures has shifted from empirical dilatations and surgery to evidence-based and complex endoscopic and surgical procedures, aiming to achieve long-term esophageal patency. Aim: The purpose of our study is to provide descriptive evidence regarding the appropriate tailored medical, endoscopic, and surgical management of benign esophageal strictures. Methods: This retrospective study includes patients with benign esophageal strictures; the data collected encompass the complete patient profiles, detailed etiologic and anatomic workups of the strictures, comprehensive imaging, as well as management and follow-up details. Technical and clinical success rates, adverse events, stricture patency, and the need for additional therapy have been evaluated. Results: Most of the strictures (80.2%) were complex, requiring advanced techniques for management. The primary treatment involved endoscopic dilation, performed with Savary-Gillard bougie dilators in 76.7% of cases and pneumatic balloon dilators in 23.3% of cases. Clinical success was achieved in 95.3% of patients, with a significant improvement in the Ogilvie dysphagia score. Patients with caustic strictures required repeated dilations over the years, compared to shorter intervals for peptic strictures. Adverse events were minimal (e.g., perforation 2.3% and bleeding 4.7%) and managed predominantly endoscopically. Refractory strictures (16.3%) required advanced interventions, including fully covered self-expandable metallic stents (fc-SEMS) and corticosteroid injections. Conclusions: Both our data and the current literature support the use of tailored endoscopic strategies as the first-choice options for managing benign esophageal strictures. Our results strongly suggest against one-size-fits-all therapeutic alternatives. Full article

Background and Clinical significance: Plummer–Vinson (PV) syndrome is a rare medical entity diagnosed when iron-deficiency anemia, dysphagia, and esophageal webs occur in the same patient. PV syndrome has been associated with different autoimmune diseases, such as celiac disease (CD). CD is a chronic multisystemic disorder affecting the small intestine, but it is recognized as having a plethora of clinical manifestations secondary to the malabsorption syndrome that accompanies the majority of cases. However, similar to PV syndrome, a high percentage of CD patients are asymptomatic, and those who are symptomatic may present with a wide variety of gastrointestinal and extraintestinal symptoms, including iron-deficiency anemia, making the diagnosis challenging. Case presentation: We present the case of a 43-year-old Caucasian female patient with a 7-year history of iron-deficiency anemia and increased bowel movements (3–4 stools/day). Upper endoscopy demonstrated a narrowing at the proximal cervical esophagus from a tight esophageal stricture caused by a smooth mucosal diaphragm. A 36F Savary–Gilliard dilator was used to manage the stenosis. The distal esophagus and stomach were normal, but scalloping of the duodenal folds was noted, and CD was confirmed by villous atrophy and positive tissue transglutaminase antibodies. Dysphagia was immediately resolved, and a glute-free diet was implemented. Conclusions: The relationship between PV syndrome and CD is still a matter of debate. Some might argue that PV syndrome is a complication of an undiagnosed CD. In cases of PV syndrome, a CD diagnosis should be considered even in the absence of typical symptoms of malabsorption.

Background: The current treatment of gastroesophageal reflux disease (GERD) is focused on decreasing gastric acid secretion. However, there is still a group of patients that do not respond to conventional therapy. Proteinase-activated receptors and purinergic receptors have been implicated in inflammation, visceral hyperalgesia and esophageal hypersensitivity. The aim of this study was to evaluate the esophageal expression of PAR2 (F2RL1) and P2RX2, P2RX3 and P2RY2 in GERD patients. Methods: A total of 53 patients with GERD and 9 healthy controls were enrolled in this study. The expression of the studied receptors was quantified using real-time PCR on esophageal biopsies from the patients with GERD and healthy controls. The correlation between the dilated intracellular spaces (DIS) score and patients’ quality of life was investigated. Results: PAR2 receptor expression was higher in ERD compared to NERD and controls (326.10 ± 112.30 vs. 266.90 ± 84.76 vs. 77.60 ± 28.50; NS). P2X2 exhibited the highest expression in NERD compared to ERD and controls (302.20 ± 82.94 vs. 40.18 ± 17.78 vs. 26.81 ± 10.27), similarly to P2Y2, which expression was higher in NERD than in ERD and controls (7321.00 ± 1651.00 vs. 5306.0 ± 1738.00 vs. 3476.00 ± 508.0). Conclusions: We found that the expression of F2RL1, P2RX2 and P2RY2 is positively correlated to the DIS score in GERD patients. Higher PAR2, P2X2 and P2Y2 expression could mediate the sensitization of the esophagus and may be associated with the higher intensity of symptoms perceived by NERD patients. Full article

Background and Clinical Significance: Mexiletine is a class 1B antiarrhythmic drug commonly prescribed for ventricular arrhythmias and neuropathic pain. It works as a blocker of the sodium channel that modulates cardiac conduction and reduces aberrant nerve signaling. While it is generally well tolerated, gastrointestinal side effects, such as nausea, vomiting, and abdominal pain, are relatively common. Esophagitis and esophageal ulcerations have been described as rare side effects; however, they are poorly documented in the literature. Esophageal ulceration induced by oral medications, termed pill esophagitis, occurs due to prolonged contact between the medication and the esophageal mucosa. Factors contributing to this phenomenon include improper administration, such as swallowing without sufficient water, taking medication before lying down, or inherent irritant properties of the drug itself. Mexiletine-induced esophageal ulceration has not been extensively reported, making such cases clinically significant and worth investigating. In particular, the prompt diagnosis of mexiletine-induced esophageal injury is essential for timely treatment initiation or the discontinuation of the drug, preventing complications such as bleeding, strictures, or perforation. Altogether, these actions are important to prevent the onset of potentially serious complications, such as bleeding, strictures, and the perforation of the esophagus. Case Presentation: Two different patients were included in this case report on mexiletine-induced esophageal ulceration: a 78-year-old woman affected by primary dilated cardiomyopathy and atrial fibrillation with high ventricular response and a 19-year-old man affected by dilated cardiomyopathy and systemic sclerosis. Conclusions: This case report underscores the importance of recognizing mexiletine-induced esophageal ulceration, and it advocates for timely diagnosis and management to optimize patient outcomes.

Background/Objectives: Superficial esophageal cancer is diagnosed by evaluating the vascular architecture, including dilation, tortuosity, caliber change, and shape, of a lesion. However, this diagnosis is subjective and requires extensive experience. Endoscopically distinguishing squamous intraepithelial neoplasia (SIN) from esophageal cancer is difficult. Thus far, only a few studies have described the endoscopic findings of SIN. Therefore, the present study aimed to investigate whether endoscopic observation of the vascular architecture of tumors is useful in differentiating SIN from superficial esophageal cancer (SCC). Methods: This study included 141 patients who were histopathologically diagnosed with SIN or SCC between 2007 and 2023. Based on endoscopic images, patients were divided into those with a regular vascular arrangement (regular group) and those with an irregular vascular arrangement (irregular group). After evaluating the clinical characteristics, propensity score matching was used to assess the association between the groups and their pathological diagnoses. Results: Of the 141 patients, 44 and 97 were in the regular and irregular groups, respectively, with a ratio of 1:2. After propensity score matching, 33 and 66 patients were included in the regular and irregular groups, respectively. There were no significant differences between the groups after matching for age, alcohol consumption, smoking status, lesion site, sex, or lesion size. The regular group had significantly more patients with SIN, whereas the irregular group had significantly more patients with esophageal cancer (p < 0.001). Conclusions: The regularity of the vascular architecture may be useful for endoscopically distinguishing between SIN and esophageal cancer. Full article

Background/Objectives: Thermotherapy is expected to assist in the prevention of arteriosclerosis and cardiovascular disease in individuals with spinal cord injuries. This study aimed to investigate the impact and underlying mechanisms of whole-body heat stress on cardiac function in patients with cervical spinal cord injury (CSCI) and healthy controls using head-out hot water immersion (HHWI). Methods: Eight male patients with complete motor CSCI and nine healthy controls were recruited. Participants were immersed for 60 min in water set at 2 °C above the resting esophageal temperature. Esophageal temperature, heart rate, and arterial pressure were monitored throughout the experiment. Before and after HHWI, echocardiography was used to measure indices of left ventricular diastolic capacity (E, E′, and A), left atrial contractility (A and A′), and left ventricular contractility [S′ and isovolumic acceleration (IVA)]. Results: Both groups exhibited an increase in body temperature and heart rate, while blood pressure remained stable. In the control group, there was a significant increase in E (67.0 ± 22.6 to 89.1 ± 13.6), E′ (9.5 ± 3.8 to 15.1 ± 4.1), A (50.0 ± 15.2 to 75.8 ± 18.2), A′ (8.1 ± 1.6 to 14.8 ± 5.9), S′ (8.7 ± 1.4 to 15.1 ± 4.5) and isovolumic acceleration (IVA) (104.2 ± 14.7 to 151.1 ± 20.6). In the CSCI group, only A (49.5 ± 9.9 to 56.9 ± 10.9) and IVA (94.4 ± 27.2 to 134.7 ± 27.7) showed a significant change. Conclusions: In the control group, heat stress increased left atrial contractility, left ventricular dilatation, and left ventricular contractility, while in patients with CSCI, left atrial contractility and left ventricular contractility improved, but there was no improvement in left ventricular diastolic function. This discrepancy in the impact of HHWI on cardiac function suggests that the sympathetic nervous system predominantly influences left ventricular dilatation during whole-body heat stress. However, other factors may also contribute to left atrial and ventricular contractility. Full article

Background: Esophageal varices, dilated submucosal veins in the lower esophagus, are commonly associated with portal hypertension, particularly due to liver cirrhosis. The high morbidity and mortality linked to variceal hemorrhage underscore the need for accurate diagnosis and effective management. The traditional method of assessing esophageal varices is esophagogastroduodenoscopy (EGD), which, despite its diagnostic and therapeutic capabilities, presents limitations such as interobserver variability and invasiveness. This review aims to explore the role of artificial intelligence (AI) in enhancing the management of esophageal varices, focusing on its applications in diagnosis, risk stratification, and treatment optimization. Methods: This systematic review focuses on the capabilities of AI algorithms to analyze clinical scores, laboratory data, endoscopic images, and imaging modalities like CT scans. Results: AI-based systems, particularly machine learning (ML) and deep learning (DL) algorithms, have demonstrated the ability to improve risk stratification and diagnosis of esophageal varices, analyzing vast amounts of data, identifying patterns, and providing individualized recommendations. However, despite these advancements, clinical scores based on laboratory data still show low specificity for esophageal varices, often requiring confirmatory endoscopic or imaging studies. Conclusions: AI integration in managing esophageal varices offers significant potential for advancing diagnosis, risk assessment, and treatment strategies. While promising, AI systems should complement rather than replace traditional methods, ensuring comprehensive patient evaluation. Further research is needed to refine these technologies and validate their efficacy in clinical practice. Full article
