Challenges in Diagnosis of Esophageal Tuberculosis.

Esophageal tuberculosis (TB) is a rare manifestation of extrapulmonary TB, accounting for <0.2% of all TB cases. Esophageal TB most commonly presents with dysphagia, odynophagia, retrosternal pain, and systemic symptoms like decreased appetite, loss of weight, and low-grade fever as associated or other presentations. We report a similar case recently encountered as an elderly male patient presented with chronic dysphagia to solids, loss of appetite, and significant loss of weight. Radiological and endoscopy pictures looked like esophageal cancer with histopathological examination (twice) negative for the same. Diagnosis of esophageal TB was confirmed by GeneXpert Ultra of biopsy sample and histopathological examination was suggestive of granulomatous esophagitis. The patient improved on 6 months antitubercular therapy. The unique aspect of this case was how the lesion mimicked an esophageal carcinoma on imaging which posed a diagnostic challenge.

A 25-Year-Old Man with a History of Substance Abuse Presenting with Pneumomediastinum Due to Methamphetamine Vapor Inhalation.

BACKGROUND There has been an increase in the use of inhalation methods to abuse drugs, including freebasing crack cocaine (alkaloid) and inhaling methamphetamine vapor. This report is of a 25-year-old man with a history of substance abuse presenting with pneumomediastinum due to methamphetamine vapor inhalation. Acute pneumomediastinum is an extremely rare complication of methamphetamine use. CASE REPORT A 25-year-old man was treated for polysubstance abuse following 9 days of methamphetamine abuse. EKG did not show any ST &T change. D-dimer was normal, at 0.4 mg/L, so we did not do further work-up for pulmonary embolism. His chest pain worsened in the Emergency Department (ED), and a physical exam demonstrated crepitation of the posterior neck, trapezius, and right scapula. A portable chest X-ray revealed subcutaneous air over the right scapular region, in addition to pneumomediastinum. The urine drug screen test was positive for methamphetamine. A chest CT was ordered, which showed a moderate-volume pneumomediastinum with soft-tissue air tracking into the lower neck and along the right chest wall. The patient underwent an esophagogram, which showed no air leak, and Boerhaave's syndrome was ruled out. His symptoms improved and he did not require any surgical intervention. CONCLUSIONS Considering the higher rates of illicit substance use, especially methamphetamine, it is important to pay attention to the associated pathologies and to keep spontaneous pneumomediastinum on the list of differentials for patients using methamphetamine, particularly those who inhale it, which can cause pneumomediastinum, even without Boerhaave's syndrome.

Detachable string magnetically controlled capsule endoscopy for the noninvasive diagnosis of esophageal diseases: A prospective, blind clinical study.

BACKGROUND: Traditional esophagogastroduodenoscopy (EGD), an invasive examination method, can cause discomfort and pain in patients. In contrast, magnetically controlled capsule endoscopy (MCE), a noninvasive method, is being applied for the detection of stomach and small intestinal diseases, but its application in treating esophageal diseases is not widespread. AIM: To evaluate the safety and efficacy of detachable string MCE (ds-MCE) for the diagnosis of esophageal diseases. METHODS: Fifty patients who had been diagnosed with esophageal diseases were prospectively recruited for this clinical study and underwent ds-MCE and conventional EGD. The primary endpoints included the sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of ds-MCE for patients with esophageal diseases. The secondary endpoints consisted of visualizing the esophageal and dentate lines, as well as the subjects' tolerance of the procedure. RESULTS: Using EGD as the gold standard, the sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of ds-MCE for esophageal disease detection were 85.71%, 86.21%, 81.82%, 89.29%, and 86%, respectively. ds-MCE was more comfortable and convenient than EGD was, with 80% of patients feeling that ds-MCE examination was very comfortable or comfortable and 50% of patients believing that detachable string v examination was very convenient. CONCLUSION: This study revealed that ds-MCE has the same diagnostic effects as traditional EGD for esophageal diseases and is more comfortable and convenient than EGD, providing a novel noninvasive method for treating esophageal diseases.

Public knowledge of button battery ingestions: A social media based cross-sectional analysis.

INTRODUCTION: Button battery (BB) ingestion injuries are a devastating and preventable event within the pediatric population. Efforts to reduce the prevalence of esophageal button battery ingestion injuries include primary preventative measures. It is integral to assess the public's baseline knowledge about BB injuries to tailor future primary prevention efforts. METHODS: This is a crowdsourcing survey-based study. Participants were notified through our institution's Twitter and Instagram accounts. RESULTS: There were 930 completed survey responses from May to June 2022. The survey found that 87% (791/910) knew that swallowing a BB could cause injury and 71% knew that it could cause death (642/905). Eight-five percent of respondents did not know what signs and symptoms to look for after BB ingestion, only 30% (99/340) of healthcare professionals felt they would know. Only 10.1% (94/930) of participants knew to give children over 12 months old honey after suspected BB ingestion. Thirty-four percent (311/930) knew that complications could still occur even after BB were removed. Seventy-seven percent (719/930) knew that a dead BB could cause injury but only 17% knew the correct way to dispose of a dead button battery (158/930). Only 8% (72/930) of participants were knew that wrapping dead BB in tape could potentially prevent injury. CONCLUSION: The current study reveals gaps in the public's understanding of BB injury including: the presentation of BB injuries; the delayed harm of BB impactions; management and mitigation strategies, and BB disposal methods. This survey provided imperative insights to help guide future education and primary prevention initiatives.

Effectiveness of antibiotic prophylaxis for acute esophageal variceal bleeding in patients with band ligation: A large observational study.

BACKGROUND: Esophageal variceal bleeding is a severe complication associated with liver cirrhosis and typically necessitates endoscopic hemostasis. The current standard treatment is endoscopic variceal ligation (EVL), and Western guidelines recommend antibiotic prophylaxis following hemostasis. However, given the improvements in prognosis for variceal bleeding due to advancements in the management of bleeding and treatments of liver cirrhosis and the global concerns regarding the emergence of multidrug-resistant bacteria, there is a need to reassess the use of routine antibiotic prophylaxis after hemostasis. AIM: To evaluate the effectiveness of antibiotic prophylaxis in patients treated for EVL. METHODS: We conducted a 13-year observational study using the Tokushukai medical database across 46 hospitals. Patients were divided into the prophylaxis group (received antibiotics on admission or the next day) and the non-prophylaxis group (did not receive antibiotics within one day of admission). The primary outcome was composed of 6-wk mortality, 4-wk rebleeding, and 4-wk spontaneous bacterial peritonitis (SBP). The secondary outcomes were each individual result and in-hospital mortality. A logistic regression with inverse probability of treatment weighting was used. A subgroup analysis was conducted based on the Child-Pugh classification to determine its influence on the primary outcome measures, while sensitivity analyses for antibiotic type and duration were also performed. RESULTS: Among 980 patients, 790 were included (prophylaxis: 232, non-prophylaxis: 558). Most patients were males under the age of 65 years with a median Child-Pugh score of 8. The composite primary outcomes occurred in 11.2% of patients in the prophylaxis group and 9.5% in the non-prophylaxis group. No significant differences in outcomes were observed between the groups (adjusted odds ratio, 1.11; 95% confidence interval, 0.61-1.99; P = 0.74). Individual outcomes such as 6-wk mortality, 4-wk rebleeding, 4-wk onset of SBP, and in-hospital mortality were not significantly different between the groups. The primary outcome did not differ between the Child-Pugh subgroups. Similar results were observed in the sensitivity analyses. CONCLUSION: No significant benefit to antibiotic prophylaxis for esophageal variceal bleeding treated with EVL was detected in this study. Global reassessment of routine antibiotic prophylaxis is imperative.

Boerhaave's Syndrome Presenting in the Setting of Third-Degree Heart Block.

Introduction: Boerhaave's syndrome, or the spontaneous transmural perforation of the esophagus, is typically thought to be due to an increase in esophageal pressure such as that which occurs during vomiting or retching. Another common etiology of esophageal perforation is esophageal instrumentation, such as during esophagogastroduodenoscopy or transesophageal echocardiography. This life-threatening condition requires prompt diagnosis and treatment to prevent patient demise. While a history of vomiting can aid in diagnosis, this history can be difficult to elicit in an unconscious patient or may be altogether absent. Additionally, Boerhaave's syndrome can present similarly to more common upper gastrointestinal or cardiac conditions. Since mortality increases with delays in diagnosis and treatment, it is imperative that clinicians maintain a high level of suspicion for Boerhaave's syndrome and initiate treatment urgently. Case Description: This report presents a 76-year-old man who presented to the emergency department after a history of several syncopal episodes and was found to be in complete heart block. Two days later, he acutely developed abdominal distention and coffee ground emesis. As the medical team was able to gather more history from the patient and his family, it was revealed that he had associated vomiting with his episodes of syncope. CT scan of the abdomen and pelvis demonstrated pneumomediastinum concerning for esophageal perforation. His clinical status subsequently deteriorated. He was intubated and a temporary transvenous pacer was placed before being transferred to our facility for emergent surgery. Discussion: Complete heart block in the setting of Boerhaave's syndrome is exceptionally rare, with only 2 cases reported in the literature. The decision to place a pacemaker in the setting of esophageal perforation/sepsis is complicated and depends on the patient's bacteremia status related to noncardiac comorbidities. Clearly this case represents the need for excellent multidisciplinary decision-making processes with excellent communication between hospital staff and all caretakers. Expeditious diagnosis and treatment of esophageal perforation is essential to prevent leaking of gastric contents into the mediastinum and worsening of cardiac complications and sepsis. Additionally, critical timing of various surgical procedures, especially the need for a permanent pacemaker implant with bacteremia is a complicated process not well described in the surgical literature.

Esophageal Lichen Planus: A Descriptive Multicenter Report.

GOALS: To better understand the characteristics, treatment approaches, and outcomes of patients with esophageal lichen planus (ELP). BACKGROUND: ELP is a rare, often unrecognized and misdiagnosed disorder. Data on this unique patient population are currently limited to small, single-center series. STUDY: A multicenter, retrospective descriptive study was conducted of adults diagnosed with ELP over a 5-year period, between January 1, 2015, and October 10, 2020, from 7 centers across the United States. RESULTS: Seventy-eight patients (average age 65 y, 86% female, 90% Caucasian) were included. Over half had at least 1 extraesophageal manifestation. Esophageal strictures (54%) and abnormal mucosa (50%) were frequent endoscopic findings, with the proximal esophagus the most common site of stricture. Approximately 20% had normal endoscopic findings. Topical steroids (64%) and/or proton pump inhibitors (74%) dominated management; endoscopic response favored steroids (43% vs. 29% respectively). Almost half of the patients required switching treatment modalities during the study period. Adjunctive therapies varied significantly between centers. CONCLUSIONS: Given its at times subtle clinical and endoscopic signs, a high index of suspicion and biopsy will improve ELP diagnosis, especially in those with extraesophageal manifestations. Effective therapies are lacking and vary significantly. Prospective investigations into optimal treatment regimens are necessary.

Plasminogen Activator Inhibitor 1 Is a Novel Faecal Biomarker for Monitoring Disease Activity and Therapeutic Response in Inflammatory Bowel Diseases.

BACKGROUND AND AIMS: Crohn's disease [CD] and ulcerative colitis [UC] require lifelong treatment and patient monitoring. Current biomarkers have several limitations; therefore, there is an unmet need to identify novel biomarkers in inflammatory bowel disease [IBD]. Previously, the role of plasminogen activator inhibitor 1 [PAI-1] was established in the pathogenesis of IBD and suggested as a potential biomarker. Therefore, we aimed to comprehensively analyse the selectivity of PAI-1 in IBD, its correlation with disease activity, and its potential to predict therapeutic response. METHODS: Blood, colon biopsy, organoid cultures [OC], and faecal samples were used from active and inactive IBD patients and control subjects. Serpin E1 gene expressions and PAI-1 protein levels and localisation in serum, biopsy, and faecal samples were evaluated by qRT-PCR, ELISA, and immunostaining, respectively. RESULTS: The study population comprised 132 IBD patients [56 CD and 76 UC] and 40 non-IBD patients. We demonstrated that the serum, mucosal, and faecal PAI-1 concentrations are elevated in IBD patients, showing clinical and endoscopic activity. In responders [decrease of eMayo ≥3 in UC; or SES-CD  50% in CD], the initial PAI-1 level decreased significantly upon successful therapy. OCs derived from active IBD patients produced higher concentrations of PAI-1 than the controls, suggesting that epithelial cells could be a source of PAI-1. Moreover, faecal PAI-1 selectively increases in active IBD but not in other organic gastrointestinal diseases. CONCLUSIONS: The serum, mucosal, and faecal PAI-1 concentration correlates with disease activity and therapeutic response in IBD, suggesting that PAI-1 could be used as a novel, non-invasive, disease-specific, faecal biomarker in patient follow-up.

Development and validation of a universal esophageal patient-reported outcome measure: The Cleveland Clinic Esophageal Questionnaire (CEQ).

OBJECTIVE: Currently, there is no validated patient-reported outcome measure (PROM) applicable to all esophageal diseases. Our objective was to create a psychometrically robust, validated universal esophageal PROM that can also objectively assess patients' quality of life (QoL). METHODS: The pilot PROM constructed based on expert opinions, literature review, and previous unpublished institutional research had 27 items covering 8 domains. It was completed by 30 patients in the outpatient clinic followed by a structured debriefing interview, which allowed for refining the PROM. The final PROM: Cleveland Clinic Esophageal Questionnaire (CEQ) included 34 items across 6 domains (Dysphagia, Eating, Pain, Reflux & Regurgitation, Dyspepsia, Dumping), each accompanied by a corresponding QoL component. Further psychometric assessment of the PROM was conducted by evaluating (1) acceptability, (2) construct validity, (3) reliability, and (4) responsiveness. RESULTS: Five hundred forty-six unique patients (median 63.7 years [54.3-71.7], 53% male [287], 86% White) completed CEQ at >90% completion within 5 minutes. Construct validity was demonstrated by differentiating scores across esophageal cancer (n = 146), achalasia (n = 170), hiatal hernia (n = 160), and other diagnoses (n = 70). Internal reliability (Cronbach alpha 0.83-0.89), and test-retest reliability (intraclass correlation coefficients 0.63-0.85) were strong. Responsiveness was demonstrated through CEQ domains improving for 53 patients who underwent surgery for achalasia or hiatal hernia (Cohen d 0.86-2.59). CONCLUSIONS: We have constructed a psychometrically robust, universal esophageal PROM that allows concise, consistent, objective quantification of symptoms and their effect on the patient. The CEQ is valuable in prognostication and tracking of longitudinal outcomes in both benign and malignant esophageal diseases.

The Effect of Nationwide Organized Cancer Screening Programs on Gastric Cancer Mortality: A Synthetic Control Study.

BACKGROUND & AIMS: Nationwide organized gastric cancer (GC) screening programs have been running for decades in South Korea and Japan. This study conducted a quasi-experimental analysis to assess the population impact of these programs on GC mortality. METHODS: We used the flexible synthetic control method (SCM) to estimate the effect of the screening programs on age-standardized GC mortality and other upper gastrointestinal (UGI) diseases (esophageal cancer and peptic ulcer) among people aged ≥40 years. World Health Organization mortality data and country-level covariates from the World Bank and the Global Burden of Diseases study were used for the analyses. We compared postintervention trends in outcome with the counterfactual trend of the synthetic control and estimated average postintervention rate ratios (RRs) with associated 95% confidence intervals (CIs). A series of sensitivity analyses were conducted. RESULTS: The preintervention fits were acceptable for the analyses of South Korea and Japan's GC mortality but poor for Japan's other UGI disease mortality. The average postintervention RRs were 0.83 (95% CI, 0.71-0.96) for GC mortality and 0.72 (95% CI, 0.57-0.90) for other UGI disease mortality in South Korea. The RR reached 0.59 by the 15th year after the initiation of nationwide screening. For Japan, the average RRs were 0.97 (95% CI, 0.88-1.07) for GC mortality and 0.93 (95% CI, 0.68-1.28) for other UGI disease mortality. Sensitivity analysis reveals the result for Japan may potentially be biased. CONCLUSIONS: South Korea's nationwide GC screening has apparent benefits, whereas the Japanese program's effectiveness is uncertain. The experiences of South Korea and Japan could serve as a reference for other countries.

Retrograde cricopharyngeus dysfunction: How does the inability to burp affect daily life?

BACKGROUND: Retrograde cricopharyngeus dysfunction (R-CPD), a condition first detailed in 1987 and termed in 2019, refers to the cricopharyngeal muscle's inability to relax to allow the retrograde passage of gas. Limited research exists on the fundamental characteristics of this condition, including its impact on one's life. The purpose of this study is to characterize R-CPD and how the inability to burp affects the social lives of people who suffer from it. METHODS: A Qualtrics survey was distributed on the subreddit "r/noburp," a community of 26,000 individuals sharing information about R-CPD. Adults aged 18-89 experiencing R-CPD symptoms were invited to participate. Participants reported on their experiences with R-CPD and its effects on social life on a 4-point Likert scale (1 = strongly disagree to 4 = strongly agree). Data was analyzed using descriptive statistics. KEY RESULTS: Among the 199 respondents, the mean age was 30.9, and gender identity was 74%/25% female/male. 99% reported inability to burp, 98% reported abdominal bloating, 93% reported socially awkward gurgling noises, 89% reported excessive flatulence, and 55% reported difficulty vomiting. Only half discussed their symptoms with their primary care provider (PCP), and 90% disagreed with receiving adequate help. Average Likert scores indicated embarrassment (3.4), anxiety/depression (3.1), negative impact on relationships (2.6), and work disruption (2.7) due to R-CPD. CONCLUSIONS & INFERENCES: R-CPD is unfamiliar to many healthcare providers, leaving patients underserved. It not only affects daily life but also personal and professional relationships. Raising awareness by understanding disease basic features may increase diagnosis and treatment rates, improving quality of life.
