RESUMO
BACKGROUND & AIMS: Brain-gut behavior therapies (BGBT) are increasingly recognized as effective therapeutic interventions for functional heartburn. However, recommendations regarding candidacy for treatment, initial treatment selection, and navigating treatment non-response have not been established for functional heartburn specifically. The aim of this study was to establish expert-based recommendations for behavioral treatment in patients with functional heartburn. METHODS: The validated RAND/University of California, Los Angeles Appropriateness Method was applied to develop recommendations. A 15-member panel composed of 10 gastrointestinal psychologists and 5 esophageal specialists ranked the appropriateness of a series of statements on a 9-point interval scale over 2 ranking periods. Statements were within the following domains: pre-therapy evaluation, candidacy criteria for BGBT, selection of initial BGBT, role of additional therapy for initial non-response to BGBT, and role of pharmacologic neuromodulation. The primary outcome was appropriateness of each intervention based on the recommendation statements. RESULTS: Recommendations for psychosocial assessment (eg, hypervigilance, symptom-specific anxiety, health-related quality of life), candidacy criteria (eg, motivated for BGBT, acknowledges the role of stress in symptoms), and treatment were established. Gut-directed hypnotherapy or cognitive behavioral therapy were considered appropriate BGBT for functional heartburn. Neuromodulation and/or additional BGBT were considered appropriate in the context of non-response. CONCLUSIONS: Gut-directed hypnotherapy and/or cognitive behavioral therapy are recommended as appropriate behavioral interventions for heartburn symptoms, depending on clinical indication, specific gut-brain targets, and preferred treatment modality (pharmacologic vs non-pharmacologic). Pre-therapy evaluation of psychosocial processes and candidacy for BGBT are important to determine eligibility for referral to psychogastroenterology services.

INTRODUCTION: Despite the high prevalence of typical symptoms of gastroesophageal reflux disease (GERD), approximately 30% of patients have functional esophageal disorders (FED) on ambulatory reflux monitoring, which may include reflux hypersensitivity (RH; defined as physiologic acid exposure but temporally correlated symptoms of reflux), or functional heartburn (FH; defined as physiologic acid exposure and negative symptom correlation). There are limited epidemiological data characterizing these conditions. We investigated demographic and socioeconomic factors as well as medical comorbidities which may predispose to FED versus pathologic GERD. METHODS: Adult patients with reflux symptoms for at least 3 months were studied with 24-h pH-impedance testing from 11/2019 to 3/2021. Participants were categorized into pathologic GERD, FH, or RH using pH-impedance data and reported symptom correlation. Demographic data, including age, gender, race/ethnicity, zip code, insurance status, and medical comorbidity data were retrospectively retrieved from the electronic medical record on all participants. RESULTS: 229 patients were included. Non-Hispanic Asian ethnicity (OR 5.65; p = 0.01), underweight BMI (OR 7.33; p = 0.06), chronic pain (OR 2.33; p < 0.01), insomnia (OR 2.83; p = 0.06), and allergic rhinitis (OR 3.90; p < 0.01) were associated with a greater risk for FED. Overweight BMI (OR 0.48; p = 0.03) and alcohol use (OR 0.57; p = 0.06) were associated with a decreased risk for FED. DISCUSSION: This is the first report of a greater risk of FED in patients with underweight BMI, insomnia, chronic pain, allergic rhinitis, or of Asian or Hispanic ethnicities. The weak associations between female gender and anxiety are corroborated in other studies. Our findings enable clinicians to better screen patients with reflux for this disorder.

BACKGROUND & AIMS: Smooth muscles of the lower esophageal sphincter (LES) and skeletal muscle of the crural diaphragm (esophagus hiatus) provide the sphincter mechanisms at the esophagogastric junction (EGJ). We investigated differences in the 3-dimensional (3D) pressure profile of the LES and hiatal contraction between healthy subjects and patients with achalasia esophagus. METHODS: We performed a prospective study of 10 healthy subjects (controls; 7 male; mean age, 60 ± 15 years; mean body mass index, 25 ± 2) and 12 patients with a diagnosis of achalasia (7 male; mean age, 63 ± 13 years; mean body mass index, 26 ± 1), enrolled at a gastroenterology clinic. Participants underwent 3D high-resolution manometry (3DHRM) with a catheter equipped with 96 transducers (for the EGJ pressure recording). A 0.5-mm metal ball was taped close to the transducer number 1 of the 3DHRM catheter. EGJ pressure was recorded at end-expiration (LES pressure) and at the peak of forced inspiration (hiatal contraction). Computed tomography (CT) scans were performed to localize the circumferential location of the metal ball on the catheter. Esophagus, LES, stomach, right and left crus of the diaphragm, and spine were segmented in each CT scan slice images to construct the 3D morphology of the region. RESULTS: The metal ball was located at the 7 o'clock position in all controls. The circumferential orientation of metal ball was displaced 45 to 90 degrees in patients with achalasia compared with controls. The 3D-pressure profile of the EGJ at end-expiration and forced inspiration revealed marked differences between the groups. The LES turns to the left as it entered from the chest into the abdomen, forming an angle between the spine and LES. The spine-LES angle was smaller in patients with achalasia (104°) compared with controls (124°). Five of the 10 subjects with achalasia had physical breaks in the left crus of the diaphragm CONCLUSIONS: Besides LES, the 3D pressure profile of the EGJ can indicate anatomic and functional abnormalities of the crural diaphragm muscle in patients with achalasia esophagus. Further studies are needed to define the nature of hiatal and crural diaphragm dysfunction in patients with achalasia of the esophagus.

Objectives: Frail patients with malnourishment due to an esophageal condition and dysphagia are often unamenable to safe surgery. Thus, in high-risk patients, less invasive techniques such as percutaneous endoscopic gastrostomy (PEG) are regarded as a safer choice. Nevertheless, as described here, PEG insertion can have rare serious complications.Materials and methods: We report the case of a frail patient with dysphagia due to a large Zenker's diverticulum and concomitant giant hiatal hernia. To improve her nutrinitional status before surgery she received a PEG after endoscopic repositioning of the hernia.Results: Within 48 hours after hernia repositioning and PEG insertion, a severe adverse event ensued: dislodgement of the PEG due to stomach reherniation.Conclusions: This case challenges the use of PEG as an only means for gastric fixation for hiatal hernia.

Nitric oxide is thought to have a role in the pathogenesis of achalasia. We performed a genetic analysis of 2 siblings with infant-onset achalasia. Exome analysis revealed that they were homozygous for a premature stop codon in the gene encoding nitric oxide synthase 1. Kinetic analyses and molecular modeling showed that the truncated protein product has defects in folding, nitric oxide production, and binding of cofactors. Heller myotomy had no effect in these patients, but sildenafil therapy increased their ability to drink. The finding recapitulates the previously reported phenotype of nitric oxide synthase 1-deficient mice, which have achalasia. Nitric oxide signaling appears to be involved in the pathogenesis of achalasia in humans.

Background: Achalasia cardia (AC) is defined as a disorder of esophageal motility whose diagnostic gold standard depends on high-resolution manometry (HRM). The invasiveness of HRM can cause difficulties in diagnosis, treatment, and follow-up for patients with AC. Thus, we aimed to investigate the function of 3D reconstruction and measurement to prove the wide application of this alternative non-invasive approach for AC. Methods: A total of 126 patients with AC and 40 healthy subjects in Tianjin Medical University General Hospital from January 2018 to October 2022 were enrolled in this retrospective study. Chest CT images of these subjects were used to reconstruct the 3D models of the esophagus, stomach, spine, left crus, and right crus. Measurements of esophagus length, volume of esophagus, gastroesophageal insertion angle (His angle), max thickness of esophageal wall, esophagus maximum transverse and longitudinal diameter, esophagus-spine angle, and spine-lower esophageal sphincter (LES) angle were applied based on the models. Results: Retrocardiac esophagus length, volume of esophagus, max thickness of esophageal wall, esophagus maximum transverse and longitudinal diameter, thoracic esophagus-spine angle, and spine-LES angle in the AC group were higher than those in the control group (all P values <0.05). Among the three subtypes of AC, thoracic esophagus length, intra-abdominal LES length, volume of esophagus, His angle, esophagus maximum transverse and longitudinal diameter, and thoracic esophagus-spine angle all presented statistical differences (all P values <0.05). Correlation analysis revealed that manometric types were positively associated with His angle [r=0.196; 95% confidence interval (CI): 0.009, 0.372; P=0.028] but negatively associated with volume of esophagus (r=-0.480; 95% CI: -0.639, -0.310; P<0.001), esophagus maximum transverse diameter (r=-0.551; 95% CI: -0.679, -0.400; P<0.001), esophagus maximum longitudinal diameter (r=-0.518; 95% CI: -0.649, -0.366; P<0.001), and thoracic esophagus-spine angle (r=-0.324; 95% CI: -0.479, -0.157; P<0.001). Conclusions: This study successfully presented the differences in esophageal length, volume, thickness, and angles between healthy subjects and different AC subtypes on the basis of 3D reconstruction and measurement. Thus, 3D model and measurement can be regarded as a good support for further research and make a valuable contribution to developing non-invasive approaches for AC management.
RESUMO
Coronavirus disease 2019 (COVID-19) predominantly causes respiratory symptoms. However, a rare segment of patients recovering from COVID-19 may develop gastrointestinal (GI) symptoms. We describe a case of a female who presented with symptoms suggestive of refractory gastroesophageal reflux disease (GERD) for 18 months following COVID-19 infection. Her symptoms included epigastric and chest pain, coughing, and vomiting. Upper endoscopy and 24-hour pH monitoring were negative. Following hospital admission due to worsening symptoms, she was diagnosed with chronic pulmonary embolism (PE) presumed to be related to COVID-19. Her reflux symptoms resolved within two days of the initiation of anticoagulation. Our findings suggest that chronic PE should be considered in patients presenting with GERD refractory to treatment following COVID-19 infection. Generally, as COVID-19 and its sequelae may masquerade as GI conditions, they should be on the differential diagnosis, especially in the post-pandemic era when routine testing has significantly declined.
RESUMO
Esophagitis dissecans superficialis (EsoDS) is a rare condition characterized by the shedding of superficial esophageal epithelium. Limited data exists on EsoDS in the pediatric population. We present a case of a 17-year-old female with chronic nausea and vomiting diagnosed with EsoDS. Endoscopy revealed esophageal mucosal sloughing, and histology confirmed esophagitis with mucosal necrosis. EsoDS is underrecognized, and its association with psychoactive medications remains unclear. Fortunately, EsoDS cases tend to resolve spontaneously without complications. Awareness of EsoDS is essential, and further research is needed to understand its prevalence and outcomes in pediatric patients.
RESUMO
A 47-year-old man with a background history of gastroesophageal reflux disease (GERD) and seasonal asthma underwent a gastroscopy for further investigation. Endoscopy revealed numerous polypoid lesions diffusely distributed in the lower third of the esophagus, with histology revealing squamous papilloma with occasional intraepithelial lymphocytes. The diagnosis was esophageal squamous papillomatosis (ESP), which is a rare condition characterized by exophytic and circumferential projections with friable mucosa diffusely spread through the esophagus with unclear etiology and malignancy risk.
RESUMO
Gastroesophageal reflux disease (GERD) is a common esophageal disorder characterized by troublesome symptoms associated with increased esophageal acid exposure. The cornerstones of therapy in this regard include treatment with acid-suppressive agents, lifestyle modifications, and dietary therapy, although the latter has not been well defined. As concerns regarding long-term proton pump inhibitor (PPI) use continue to be explored, patients and healthcare providers are becoming increasingly interested in the role of diet in disease management. However, dietary interventions lack evidence of the synthesis effect of functional foods. The following is a review of dietary therapy for GERD, emphasizing food components' impact on GERD pathophysiology and management. Although the sequential dietary elimination of food groups is a common practice, the literature supports broader intervention, including reduced overall sugar intake, increased dietary fiber, and changes in overall eating practices. While the primary concern of food companies is to provide safe products, the caloric, nutritional, and functional composition of foods is also generating interest in the food industry due to consumers' concerns.

The laparoscopic adjustable gastric banding (LAGB) surgery is a minimally invasive procedure performed to help with weight loss in patients with advanced obesity with a body mass index (BMI) of >40 kg/m² or above 35 kg/m² with comorbid obesity-related health conditions (hypertension, type two diabetes mellitus, obstructive sleep apnea, etc). Although this surgery is effective for weight loss, it is imperative that close follow-up and aftercare are conducted in order to circumvent severe and rare esophageal and pulmonary complications. We report a case of systemic pulmonary and esophageal complications associated with LAGB that required immediate medical and surgical intervention in a female patient. She underwent her surgery in Mexico, and she did not receive any follow-up care for 12 years, which seemingly led to this preventable situation.
RESUMO
Killian-Jamieson diverticula (KJD) and Zenker's diverticula (more common) share similar pathophysiology but are considered to be different types of phrenoesophageal diverticula. A 55-year-old female presented to the clinic with chronic dysphagia, halitosis, and regurgitation. Imaging modalities confirmed a Killian-Jamieson diverticulum, explaining her symptoms. She was offered different treatment options and decided to proceed with a less invasive endoscopic approach. Physicians should be aware of the variable presentations of KJD and the different available treatments as newer techniques are becoming more popular and preferable by patients.
RESUMO
Reflux hypersensitivity, recently introduced by Rome IV as a new functional esophageal disorder, is currently considered as the presence of typical heartburn symptoms in patients with normal upper endoscopy and esophageal biopsies, normal esophageal pH test and with evidence of a close correlation between patients' heartburn and reflux events. Reflux hypersensitivity is very common and together with functional heartburn accounts for more than 90% of the heartburn patients who failed treatment with proton pump inhibitor twice daily. In addition, reflux hypersensitivity affects primarily young to middle aged women, commonly overlaps with another functional gastrointestinal disorders, and is often associated with some type of psychological comorbidity. Diagnosis is made by using endoscopy with esophageal biopsies, pH-impedance, and high-resolution esophageal manometry. Reflux hypersensitivity is primarily treated with esophageal neuromodulators, such as tricyclic anti-depressants and selective serotonin reuptake inhibitors among others. Surgical anti-reflux management may also play an important role in the treatment of reflux hypersensitivity.
RESUMO
Swallowing involves complex coordination of the neuromuscular anatomy and physiology of the oropharynx and esophagus, controlled by the enteric and central nervous systems. Dysphagia is classified as either oropharyngeal or esophageal and results from mechanical or structural disturbances. Videofluoroscopy, fiberoptic endoscopic evaluation of swallowing, barium swallow, manometry, and endoscopy are common modalities utilized in diagnosis, but none is as important as a patient's history. Functional dysphagia is a diagnosis of exclusion and is based on Rome criteria. Its mechanism is unknown but potentially related to visceral hypersensitivity, inappropriate pain perception, or unidentified contraction abnormalities. Its management is mainly supportive; however, there is literature to suggest, but not confirm, benefit with the use of antidepressants. Continued understanding of functional dysphagia and other functional esophageal disorders, including globus sensation, will require further investigation into diagnostic algorithms and finding treatment methods.

We describe a patient with dysphagia. The results of endoscopy, CT scan and echoendoscopy were normal. High-resolution manometry (HRM) showed esogastric junction dysfunction and hypercontractile peristaltic disorder. These HRM abnormalities completely disappeared after pneumatic esophageal dilatation. We discuss the treatment options and recovery of peristalsis after balloon dilatation.
