Background/Objective: Patients who have undergone Billroth II gastrectomy may develop gastroparesis, hypomotility, and reflux esophagitis. These patients are at risk of aspiration of gastric contents into the lungs when subsequently sedated for Endoscopic Retrograde Cholangiopancreatography (ERCP) procedures. The aim of this study was to compare conscious sedation and deep sedation in terms of pulmonary complications in this selected cohort. Methods: Patients who had previously undergone Billroth II surgery and underwent ERCP procedure with sedation for gallstones or biliary tract strictures in a tertiary hospital between January 2020 and September 2023 were studied. Patient records were retrospectively obtained from the hospital information system. All the patients were divided into two groups as conscious sedation (Group CS) and deep sedation (Group DS). The groups were compared statistically in terms of pulmonary complications. Results: A total of 63 ERCP procedures were performed on 28 patients who had undergone Billroth II gastrectomy. There were 37 procedures involving conscious sedation (Group CS) and 26 involving deep sedation (Group DS). No statistically significant difference was found regarding pulmonary aspiration (p = 0.297) and other respiratory complications such as laryngospasm or desaturation between the two groups. In Group DS, it was observed that vomiting incidence was higher (p = 0.012), and airway maneuver requirements were increased (p = 0.007). Conclusions: In patients who have undergone Billroth II gastrectomy, both conscious sedation and deep sedation techniques can be used effectively during ERCP procedures. The complication rates and patient outcomes of the two techniques are comparable. The occurrence of respiratory complications leading to adverse post-procedural outcomes requires careful monitoring and meticulous follow-up for these patients. Full article

Background and Aims: Esophageal atresia (EA) and tracheoesophageal fistula (TEF) are rare but serious congenital anomalies requiring early surgical intervention. Over the past two decades, minimally invasive surgical (MIS) approaches—particularly thoracoscopic repair—have gained traction, aiming to reduce postoperative morbidity while maintaining surgical efficacy. Objective: This narrative review provides a comprehensive overview of the evolution and current status of MIS techniques for EA/TEF, assessing their clinical outcomes, technical challenges, and implications for patient care. Methods: A structured literature search was conducted to identify clinical studies, reviews, and reports on thoracoscopic, robotic-assisted, and endoscopic approaches to EA/TEF. Emerging adjuncts, including tissue engineering, botulinum toxin use, and magnet-assisted anastomosis, were also reviewed. Results: Thoracoscopic repair has demonstrated comparable anastomotic success rates to open surgery (approximately 85–95%) with significantly reduced rates of musculoskeletal complications, such as scoliosis and chest wall deformities (reported in less than 10% of cases, compared to up to 40% in open approaches). Robotic-assisted and endoscopic-assisted techniques have enabled improved visualization and precision in anatomically challenging cases, although their use remains limited to high-resource centers with specialized expertise. Common postoperative complications include anastomotic stricture (30–50%), gastroesophageal reflux disease (35–70%), and respiratory morbidity, necessitating long-term multidisciplinary follow-up. Recent innovations in simulation-based training and bioengineered adjuncts have facilitated safer MIS adoption in neonates. Conclusions: Minimally invasive techniques have improved the surgical management of EA/TEF, though challenges remain regarding technical complexity, training, and resource availability. Continued innovation and collaborative research are essential for advancing care and ensuring optimal outcomes for affected infants. Full article

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.

Background/Objectives: Esophageal anastomotic leaks (EALs) are among the most feared complications following upper gastrointestinal surgery, particularly esophagectomy, given their profound impact on patient outcomes and healthcare resource utilization. This study aims to synthesize the evidence and determine the most effective interventions for achieving leak closure in patients with esophageal anastomotic leaks. Methods: This umbrella review followed PRISMA guidelines. A comprehensive search was conducted in PubMed, the Web of Science, Scopus, Google Scholar, Cochrane, and PROSPERO. Systematic reviews/meta-analyses on esophageal anastomotic leak management were included. The outcomes analyzed included leak closure success, mortality, complications, hospital stay, and costs. Data were synthesized narratively, with disagreements resolved by a third reviewer. Results: A systematic search identified 730 records, from which six systematic reviews and meta-analyses (evaluating 65 studies and 2186 patients) met the inclusion criteria. Most studies compared endoscopic vacuum therapy (EVT) and self-expanding metal stents (SEMSs) for EALs, with Germany contributing the majority. EVT consistently demonstrated superior leak closure rates and lower mortality compared to SEMSs, with pooled odds ratios favoring EVT. EVT also showed reduced complication rates, particularly fewer major adverse events, although with a slightly higher risk of post-therapy strictures. Hospital stay durations varied, with some studies reporting shorter treatment periods for EVT but no significant differences in the overall hospitalization length. Limited data suggested that EVT incurs higher treatment costs, largely due to intensive care unit stays. Conclusions: EVT is the most effective intervention for EALs, offering superior leak closure, lower mortality, and fewer complications. However, its economic impact requires further evaluation.

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 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: Although heartburn and reflux are frequently reported in ulcerative colitis [UC], the correlation between UC and gastroesophageal reflux disease [GERD], and its complications, esophageal stricture and Barrett’s esophagus [BE], is not well understood. This study aims to examine the prevalence and associated risk of GERD and its complications within the UC population. Methods: We analyzed the National Inpatient Sample (NIS) dataset, consisting of 7,159,694 patients, comparing GERD patients with and without UC to those without GERD. We assessed the degree of colonic involvement in UC and the occurrence of esophageal complications. Bivariate analyses were conducted using the chi-squared test or Fisher exact test (two-tailed). Results: A higher prevalence of GERD (23.0% vs. 16.5%) and GERD phenotypes, such as non-erosive reflux disease (NERD) (22.3% vs. 16%) and erosive esophagitis (EE) (1.2% vs. 0.6%), was found in UC patients (p < 0.01), including pancolitis, proctitis, proctosigmoiditis, left-sided colitis, and indetermined UC (with undefined colonic involvement). UC patients were more likely to develop GERD (1.421), NERD (1.407), and EE (1.681) (p < 0.01). A higher prevalence of esophageal stricture (16.9 vs. 11.4 per 10,000 patients) and BE without dysplasia (94.5 vs. 39.3 per 10,000 patients) was found in UC (p < 0.05). The odds of developing BE without dysplasia were higher (1.892) in patients with UC (p < 0.01), including ulcerative pancolitis, proctitis, and indeterminate UC (OR of 1.657, 3.328, and 1.996, respectively) (p < 0.05). Conclusions: Our study demonstrates an increased risk of developing GERD and its complications in UC. This highlights the importance of vigilant monitoring and early intervention to minimize associated GERD-related risks in patients with UC. Full article

Background: Esophageal self-expandable metal stents (SEMS) are an important endoscopic tool. These stents have now been adapted successfully to manage post-bariatric surgery complications such as anastomotic leaks and strictures. In centers of expertise, this has become the primary standard-of-care treatment given its minimally invasive nature, and that it results in early oral feeding, decreased hospitalization, and overall favorable outcomes. Self-expandable metal stents (SEMS) fractures are a rare complication of unknown etiology. We aimed to investigate possible causes of SEMS fractures and highlight a unique endoscopic approach utilized to manage a fractured and impaled SEMS. Methods: This is a retrospective study of consecutive patients who underwent esophageal SEMS placement between 2015–2021 at a tertiary referral center to identify fractured SEMS. Patient demographics, stent characteristics, and possible etiologies of fractured SEMS were identified. A comprehensive literature review was also conducted to evaluate all prior cases of fractured SEMS and to hypothesize fracture theories. Results: There were seven fractured esophageal SEMS, of which six were used to manage post-bariatric surgery complications. Five SEMS were deployed with their distal ends in the gastric antrum and proximal ends in the distal esophagus. All stents fractured within 9 weeks of deployment. Most stents (5/7) were at least 10 cm in length with fractures commonly occurring in the distal third of the stents (6/7). The wires of a fractured SEMS were embedded within the esophagogastric junction in one case, prompting the use of an overtube that was synchronously advanced while steadily extracting the stent. Discussion: We suggest the following four etiologies of SEMS fractures: anatomical, physiological, mechanical, and chemical. Stent curvature at the stomach incisura can lead to strain- and stress-related fatigue due to mechanical bending with exacerbation from respiratory movements. Physiologic factors (gastric body contractions) can result in repetitive squeezing of the stent, adding to metal fatigue. Intrinsic properties (long length and low axial force) may be contributing factors. Lastly, the stomach acidic environment may cause nitinol-induced chemical weakness. Despite the aforementioned theories, SEMS fracture etiology remains unclear. Until more data become available, it may be advisable to remove these stents within 6 weeks. Full article

Background: Cervical esophageal reconstruction is vital to improve the quality of life in cancer surgery patients. Microsurgery is crucial in providing vascularized tissue for defect repair, particularly in secondary cases with a higher risk of failure due to larger defects and damage from previous surgery and radiotherapy. The purpose of this study was to describe the clinical characteristics of a series of patients who underwent secondary repair of esophageal defects and provide practical information for the management and treatment of such cases based on the authors’ experience and the literature review. Methods: We retrospectively reviewed the electronic medical records of the Plastic Surgery Clinic at the University of Trieste to identify cases of patients who underwent secondary esophageal microsurgical reconstructions following oncological surgery. Patient demographics, the etiology of esophageal defects, previous surgical history, and preoperative assessments were collected from medical records. Surgical techniques utilized for reconstruction, such as pedicled flaps or free tissue transfers, were documented along with intraoperative information. Postoperative outcomes, including complications, graft viability, and functional outcomes, were evaluated during follow-up. Results: We treated 13 cases of secondary esophageal reconstructions between 2011 and 2022. Most commonly, Antero-Lateral Thigh (ALT) flaps were used in 10 cases, while 2 cases employed a radial forearm flap (RFF), and 1 case employed a chimeric parascapular flap. No flap failures occurred during a median 50-month follow-up. One ALT flap patient experienced postop stricture but maintained swallowing ability. A single tracheoesophageal fistula occurred in an RFF patient with a history of radiotherapy and complete lymph node dissection. Conclusions: Cervical esophageal reconstruction significantly impacts patients’ quality of life by restoring oral feeding and phonation. When local flaps fall short, microsurgical reconstruction with intestinal flaps is valuable but is burdened by limitations. For challenging secondary cases, ALT or RFF flaps emerge as safer options due to their robust pedicles, yielding low complication rates and positive functional outcomes. Full article

Eosinophilic Gastrointestinal Disorders (EGIDs) are a group of conditions characterized by abnormal eosinophil accumulation in the gastrointestinal tract. Among these EGIDs, Eosinophilic Esophagitis (EoE) is the most well documented, while less is known about Eosinophilic Gastritis (EoG), Eosinophilic Enteritis (EoN), and Eosinophilic Colitis (EoC). The role of endoscopy in EGIDs is pivotal, with applications in diagnosis, disease monitoring, and therapeutic intervention. In EoE, the endoscopic reference score (EREFS) has been shown to be accurate in raising diagnostic suspicion and effective in monitoring therapeutic responses. Additionally, endoscopic dilation is the first-line treatment for esophageal strictures. For EoG and EoN, while the literature is more limited, common endoscopic findings include erythema, nodules, and ulcerations. Histology remains the gold standard for diagnosing EGIDs, as it quantifies eosinophilic infiltration. In recent years, there have been significant advancements in the histological understanding of EoE, leading to the development of diagnostic scores and the identification of specific microscopic features associated with the disease. However, for EoG, EoN, and EoC, precise eosinophil count thresholds for diagnosis have not yet been established. This review aims to elucidate the role of endoscopy and histology in the diagnosis and management of the three main EGIDs and to analyze their strengths and limitations, their interconnection, and future research directions.

Eosinophilic esophagitis (EoE) disease activity can be caused by treatment non-adherence. Medication possession ratio (MPR) is an established metric of medication adherence. A higher MPR correlates with better outcomes in several chronic diseases, but MPR has not been investigated with respect to EoE. A retrospective cohort study was performed using an established EoE registry for the years 2005 to 2020. Treatment periods were identified, MPRs were calculated, and medical records were assessed for histologic remission (<15 eos/hpf), dysphagia, food impaction, stricture occurrence, and esophageal dilation that corresponded to each treatment period. In total, 275 treatment periods were included for analysis. The MPR in the histologic remission treatment period group was 0.91 (IQR 0.63–1) vs. 0.63 (IQR 0.31–0.95) for the non-remission treatment period group (p < 0.001). The optimal MPR cut-point for histologic remission was 0.7 (Sen 0.66, Spec 0.62, AUC 0.63). With MPRs ≥ 0.7, there were significantly increased odds of histologic remission (odds ratio 3.05, 95% confidence interval 1.79–5.30) and significantly decreased odds of dysphagia (OR 0.27, 95% CI 0.15–0.45), food impaction (OR 0.26, 95% CI 0.11–0.55), stricture occurrence (OR 0.52 95% CI 0.29–0.92), and esophageal dilation (OR 0.29, 95% CI 0.15–0.54). Assessing MPR before repeating an esophagogastroduodenoscopy may decrease unnecessary procedures in the clinical management of eosinophilic esophagitis. Full article

Cancer pain is one of the most disabling symptoms complained by cancer patients, with a crucial impact on physical and psychological well-being. Botulinum neurotoxins (BoNTs) type A and B have emerged as potential interventions for chronic pain; however, their role in these patients is still debated. Thus, this systematic review of randomized controlled trials aimed at assessing the effects of BoNT treatment for cancer pain to guide physicians in an evidence-based approach integrating BoNT in cancer care. Out of 5824 records, 10 RCTs satisfied our eligibility criteria and were included in the present work for a total of 413 subjects with several cancer types (breast, head and neck, esophageal, and thoracic/gastric cancers). While some studies demonstrated significant pain reduction and improved quality of life post-BoNT-A injections, outcomes across different cancer types were inconclusive. Additionally, several effects were observed in functioning, dysphagia, salivary outcomes, esophageal strictures, gastric emptying, and expansions. This review emphasizes the need for further standardized research to conclusively establish the efficacy of BoNT in comprehensive cancer pain management. Full article
