Measuring and improving quality in esophageal care and swallowing disorders.

Evaluating clinical care through quality-related metrics is increasingly common. There are now numerous quality statements and indicators related to the medical management of benign and pre-malignant esophageal diseases. Expert consensus leveraging evidence-based recommendations from published society guidelines has been the most frequently used basis for developing esophageal quality statements. While surgical care of patients with esophageal malignancies, including squamous cell carcinoma, has also been developed, those related to benign esophageal disease now include domains of diagnosis, treatment, and monitoring for gastroesophageal reflux disease, eosinophilic esophagitis (EoE), achalasia, and Barrett's esophagus (BE). Several recent studies evaluating adherence to quality metrics affirm substantial variation in practice patterns with opportunities for improvement in care across esophageal diseases. In particular, patient education regarding treatment options in achalasia, frequency of esophageal biopsies among patients with dysphagia to evaluate for EoE, and endoscopic evaluation within a BE segment are areas identified to have need for improvement. As the management of esophageal diseases becomes more complex and interdisciplinary, adherence to quality metrics may be a source of standardization and improvement in delivery and ultimately patient outcomes. Indeed, the development of national quality databases has resulted in a significant growth in the use of these metrics for quality improvement activities and may form the basis for future inclusion in quality reporting and payment programs.

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.

Esophageal lichen planus: Current knowledge, challenges and future perspectives.

Lichen planus (LP) is a frequent, chronic inflammatory disease involving the skin, mucous membranes and/or skin appendages. Esophageal involvement in lichen planus (ELP) is a clinically important albeit underdiagnosed inflammatory condition. This narrative review aims to give an overview of the current knowledge on ELP, its prevalence, pathogenesis, clinical manifestation, diagnostic criteria, and therapeutic options in order to provide support in clinical management. Studies on ELP were collected using PubMed/Medline. Relevant clinical and therapeutical characteristics from published patient cohorts including our own cohort were extracted and summarized. ELP mainly affects middle-aged women. The principal symptom is dysphagia. However, asymptomatic cases despite progressed macroscopic esophageal lesions may occur. The pathogenesis is unknown, however an immune-mediated mechanism is probable. Endoscopically, ELP is characterized by mucosal denudation and tearing, trachealization, and hyperkeratosis. Scarring esophageal stenosis may occur in chronic courses. Histologic findings include mucosal detachment, T-lymphocytic infiltrations, epithelial apoptosis (Civatte bodies), dyskeratosis, and hyperkeratosis. Direct immuno-fluorescence shows fibrinogen deposits along the basement membrane zone. To date, there is no established therapy. However, treatment with topical steroids induces symptomatic and histologic improvement in two thirds of ELP patients in general. More severe cases may require therapy with immunosuppressors. In symptomatic esophageal stenosis, endoscopic dilation may be necessary. ELP may be regarded as a precancerous condition as transition to squamous cell carcinoma has been documented in literature. ELP is an underdiagnosed yet clinically important differential diagnosis for patients with unclear dysphagia or esophagitis. Timely diagnosis and therapy might prevent potential sequelae such as esophageal stenosis or development of invasive squamous cell carcinoma. Further studies are needed to gain more knowledge about the pathogenesis and treatment options.

[Idiopathic esophageal submucosal hematoma during antithrombotic therapy for essential thrombocythemia].

A 73-year-old woman was hospitalized with sudden chest pain and hematemesis. Chest computed tomography and upper gastrointestinal endoscopy revealed an idiopathic submucosal hematoma from the cervical esophagus to the esophagogastric mucosal junction. Idiopathic esophageal submucosal hematoma is often prone to a bleeding tendency of an underlying disorder. The patient had a history of essential thrombocythemia (ET) and was taking aspirin. She successfully recovered after aspirin discontinuation and conservative treatment; however, died of cardiopulmonary arrest in the ward on day 9 of hospitalization. The autopsy revealed that the cause of death was pulmonary thromboembolism. This is the first report of ET with submucosal hematoma of the esophagus. The possibility of an esophageal submucosal hematoma should be considered when patients with ET complain of chest pain since ET and treatment with aspirin are considered risk factors for bleeding. Additionally, close attention should be focused on the risk of developing thrombosis if a patient with myeloproliferative neoplasm is required to discontinue antithrombotic therapy due to a bleeding event.

Oesophageal Tuberculosis: A Systematic Review Focusing on Clinical Management.

Oesophageal tuberculosis, an uncommon form of extrapulmonary tuberculosis, has been reported mainly as small case series and the literature is heterogeneous. A systematic review to characterize the clinical presentation, evaluation and management of oesophageal tuberculosis was performed. Electronic databases were searched with keywords: esophagus OR esophageal AND tuberculosis. We included original papers and case series (> 4 patients) with oesophageal tuberculosis. Twenty-two studies reporting 311 patients were included. Mean age in most of the studies was 31-51 years and male gender constituted 50.5% patients. Dysphagia (72.3%), odynophagia (22.4%) and chest pain (31.3%) were predominant symptoms. Mid-oesophagus was the commonest site of involvement (88%). Endoscopic findings included ulcers (59.9%), submucosal bulge (31.7%), extrinsic compression (24.8%) and pseudotumour (5.8%). On endoscopic ultrasound, presence of hypoechoic (69.5%), heteroechoic (47.6%) and matted (86.3%) mediastinal lymph nodes and oesophageal wall involvement (67.3%) were common findings. Computed tomography showed mediastinal lymphadenopathy (76.5%) and oesophageal thickening (52.1%). Diagnosis was confirmed by granuloma (72.3%) and acid fast bacilli positivity (32.5%) in mots patients. Response to antitubercular therapy was excellent; 97.7% patients recovered and 2.3% patients died. Surgery (14.5%) and oesophageal stenting (11.4%) were required infrequently. Oesophageal tuberculosis should be considered in endemic regions as a cause of dysphagia because early treatment is associated with excellent outcomes.

Real world management of esophageal ulcers: analysis of their presentation, etiology, and outcomes.

BACKGROUND AND STUDY AIMS: Esophageal ulcers are a rare cause of upper gastrointestinal morbidity and may be due to different etiologies. We sought to systematically evaluate patients with esophageal ulcers and describe their presentations, endoscopic findings, etiologies, treatments, and outcomes. PATIENTS AND METHODS: Patients diagnosed with esophageal ulcers over an 11-year period were retrospectively identified from our institution's electronic medical records. RESULTS: We identified 100 patients with esophageal ulcers (0.49% of patients undergoing upper endoscopy). Half of them presented due to gastrointestinal bleeding and three-quarters were admitted to the hospital. The majority were in the lower esophagus. Twenty-two unique etiologies, including multiple iatrogenic causes, were diagnosed in 91 of the cases. The most common etiology was gastroesophageal reflux disease (57%), followed by non-steroidal anti-inflammatory drug use (7%), malignancies (3%), vomiting (3%), caustic ingestion (2%), pill esophagitis (2%) and radiation (2%). Many etiologies showed a predilection for specific segments of the esophagus. Nine ulcers required endoscopic intervention and all were treated successfully. Repeat endoscopies were performed 5 times for diagnostic or "second look" reasons, none of which changed the patients' diagnosis or treatment. No patients required surgery or stricture dilation. One patient's ulcer was complicated by perforation and he subsequently died. Four other patients died from non-ulcer related causes. CONCLUSIONS: While the majority of ulcers were due to gastroesophageal reflux disease, 22 different etiologies were identified. Many were due to medication or iatrogenic causes. Repeat endoscopy did not appear to be helpful. While the incidence was low, they were frequently associated with significant morbidity.

Long-Term Self-Expandable Metal Stent (SEMS) for Esophageal Variceal Bleeding: A Picture of the Natural History.

INTRODUCTION: We aim to discuss the utility of self-expandable esophageal metal stent (SEMS) in variceal bleeding in challenging cases. METHODS: Case description, discussion on patient management and decision-making process in an uncommon situation, from a multidisciplinary point of view. RESULTS: We report a case of a cirrhotic patient with refractory variceal bleeding who underwent a SEMS placement, which remained in situ for 9 months. This decision was based on the initial poor status and short life expectancy, limiting the consideration of other options for lowering portal hypertension, along with an underlying prothrombotic predisposition. However, the patient's general and hepatic improvement and the development of dysphagia led to the SEMS removal, exposing a large esophageal-tracheal fistula. DISCUSSION: Early patient evaluation, risks of long-term SEMS, and life expectancy should be taken in consideration before SEMS placement.

Gastric metastasis presenting as an overt upper gastrointestinal bleeding treated with chemoembolisation in a patient diagnosed with papillary thyroid carcinoma.

We present a case of a patient with known papillary thyroid carcinoma presenting with overt upper gastrointestinal bleeding from a metastatic gastric mass. The gastric mass was diagnosed through transnasal endoscopy with tissue biopsies, revealing papillary thyroid carcinoma cells on histopathological studies. Bleeding was persistent despite standard medical therapy. Chemoembolisation of the major feeding vessels of such tumour provided resolution of bleeding.

Issues and controversies in esophageal inlet patch.

The proximal esophagus is rarely examined, and its inspection is often inadequate. Optical chromoendoscopy techniques such as narrow band imaging improve the detection rate of inlet patches in the proximal esophagus, a region in which their prevalence is likely underestimated. Various studies have reported correlations between these esophageal marks with different issues such as Barrett's esophagus, but these findings remain controversial. Conflicting reports complicate the process of interpreting the clinical features of esophageal inlet patches and underestimate their importance. Unfortunately, the limited clinical data and statistical analyses make reaching any conclusions difficult. It is hypothesized that inlet patches are correlated with various esophageal and extraesophageal symptoms, diagnoses and the personalized therapeutic management of patients with inlet patches as well as the differential diagnosis for premalignant lesions or early cancers. Due to its potential underdiagnosis, there are no consensus guidelines for the management and follow up of inlet patches. This review focuses on questions that were raised from published literature on esophageal inlet patches in adults.

Comparison of risk scores and shock index in hemodynamically stable patients presenting to the emergency department with nonvariceal upper gastrointestinal bleeding.

OBJECTIVE: Risk assessment in nonvariceal upper gastrointestinal bleeding (UGIB) is not well validated and remains unclear in hemodynamically stable patients at emergency department admission. We compared the prognostic value of risk-scoring systems for predicting adverse outcomes in patients with nonvariceal UGIB and normotension. PARTICIPANTS AND METHODS: A single-center prospective observational study was carried out. Patients with consecutive nonvariceal UGIB, presenting with normotension (systolic blood pressure ≥90 mmHg) to the emergency department, were included. We compared the areas under the curves (AUC) of Glasgow Blatchford score (GBS), the pre-endoscopy Rockall score, AIMS65, the shock index, and the modified shock index with respect to adverse outcomes defined as embolization, surgery, ICU admission, rebleeding, and in-hospital mortality. RESULTS: In total, 1233 patients were included. Adverse outcomes occurred in 165 (13.4%) patients; in-hospital mortality was 1.2%. AUC of the GBS for adverse outcome was higher than that of the shock index, but not significantly different (0.647 vs. 0.569, P=0.23). AUC values of the modified shock index, AIMS65, and the pre-endoscopy Rockall score were 0.565, 0.593, and 0.533, respectively. The cut-off value of the GBS (≥8) was associated with 85% sensitivity and 35% specificity for predicting adverse outcome. CONCLUSION: Pre-existing risk scores have shown suboptimal predictive ability for adverse events in normotensive patients with nonvariceal UGIB. The GBS (≥8) might help to identify patients prone to adverse events; however, further studies with risk scores or new scores are needed because of the low accuracy of these scores.

Clinical presentations, management, and outcomes of acute esophageal necrosis: a systemic review.

BACKGROUND: To review all the reported literature on acute esophageal necrosis. RESEARCH METHODS: Databases were searched using the special Medical Subject Heading (MeSH) terms. All the available reported cases of acute esophageal necrosis were analyzed. RESULTS: A total of 154 cases were identified and 130 cases were analyzed. The mean age of presentation was 61 years, and 70% of cases were males. The most common presenting symptoms were hematemesis in 66%, shock in 36%, melena in 33%, abdominal or substernal pain in 28%. The most common comorbidities reported were diabetes in 38%, hypertension in 37%, alcohol abuse in 25%, and chronic kidney disease in 16%. On upper endoscopy, 51% had a distal disease, 36% had pan esophageal, and only 2% had a proximal disease. 84% of patients were treated with IV Proton Pump Inhibitors, 22% received transfusions, 23% got antibiotics for underlying sepsis, 14% also received sucralfate, and 4% required surgery for treatment. The mortality rate was 32%, while perforation was reported in 5% and stricture formation reported in 9% of patients. CONCLUSIONS: Patients with acute esophageal necrosis can have a favorable outcome if treated appropriately.

Sarcoidosis Involving the Gastrointestinal Tract: Diagnostic and Therapeutic Management.

Involvement of the gastrointestinal (GI) tract is an infrequent extrathoracic presentation of sarcoidosis. We reviewed 305 cases of GI involvement reported in 238 patients, in whom GI sarcoidosis was the first sign of the disease in half the cases. The disease does not affect the GI tract uniformly, with a clear oral-anal gradient (80% of reported cases involved the esophagus, stomach, and duodenum). Clinicopathological mechanisms of damage may include diffuse mucosal infiltration, endoluminal exophytic lesions, involvement of the myenteric plexus, and extrinsic compressions. Ten percent of patients presented with asymptomatic or subclinical disease found on endoscopy. The diagnosis is relevant clinically because 22% of cases reviewed presented as life threatening. In addition, initial clinical/endoscopic findings may be highly suggestive of GI cancer. The therapeutic approach is heterogeneous and included wait-and-see or symptomatic approaches, glucocorticoid/immunosuppressive therapy, and surgery. Sarcoidosis of the gut is a heterogeneous, potentially life-threatening condition that requires a multidisciplinary approach and early clinical suspicion to institute personalized therapeutic management and follow-up.

Comprehensive review of acute oesophageal necrosis.

Acute oesophageal necrosis, also known as 'black oesophagus', is a rare condition characterised by the black discolouration of the oesophageal mucosa on endoscopy and involves the distal oesophagus in majority of cases but may also extend proximally. A number of conditions are found to be associated with it and it is thought to occur due to a combination of hypovolaemia and inadequate oesophageal protective mucosal barrier function. Gastric secretions may have a direct effect on the oesophageal mucosa. We present a case of a woman who presented with haematemesis and significant hypotension after a session of haemodialysis. Black oesophagus was confirmed on esophagogastroduodenoscopy. She was given two units of packed red blood cells and one unit of platelets, and started on a pantoprazole infusion. However, despite rigorous attempts at resuscitation the patient failed to recover.
