Background: Hypercontractile esophagus is a rare hypercontractile esophageal motility disorder. The etiology of hypercontractile esophagus is unknown but an association between acid reflux and hypercontractile esophagus has been suggested. We present the first report on the use of potassium-competitive acid blockers in the treatment of hypercontractile esophagus.
Case Presentation: A 43-year-old man presented with dysphagia, chest pain and regurgitation for a period of 1 year. Initial workup showed a twisted lumen with abnormal contractions in the distal esophagus during upper gastrointestinal endoscopy and abnormal acid exposure under 24-h esophageal pH monitoring. The use of standard-dose proton pump inhibitors didn't relieve his symptoms. Subsequent high-resolution esophageal manometry made a diagnosis of hypercontractile esophagus. Treatment with vonoprazan resulted in symptomatic resolution and abnormal contractions were no longer detected on follow-up high-resolution manometry.
Conclusions: Potassium-competitive acid blockers like vonoprazan offer an alternative therapeutic method for patients with hypercontractile esophagus who are refractory to proton pump inhibitor therapy. The use of potassium-competitive acid blockers in hypercontractile esophagus warrants further research and may provide evidence for an acid-related etiology of hypercontractile esophagus.

Noncardiac chest pain is a challenging condition often encountered by primary care providers, emergency medicine physicians, and gastroenterologists. It is frequently accompanied by persistent symptoms, diagnostic uncertainty, decreased quality of life, and high health care burden. Gastroesophageal reflux disease is the most common esophageal cause followed by functional chest pain, and at least half of patients with noncardiac chest pain have psychiatric comorbidities such as anxiety or depression.

Background: Eosinophilic esophagitis (EoE) presents with various esophageal motility disorders, and some cases of hypercontractile esophagus (HE) are associated with eosinophilic esophageal myositis (EoEM). This study aimed to compare the clinical characteristics of patients with EoE and EoEM according to their esophageal motility.
Methods: The 28 patients with EoE and 2 patients with EoEM were divided into three groups based on esophageal motility: normal motility group, hypomotility group, and spastic contraction group.

Background/aims: Chicago classification version 4.0 enhances the diagnosis of esophageal motility disorders using position change and provocative tests such as multiple rapid swallows and a rapid drink challenge. This study investigates the diagnostic role of the rapid drink challenge based on Chicago classification 4.

Background: High-resolution Manometry (HRM) is the most sensitive and specific test available for clinical assessment of hiatal hernia (HH), a common condition defined as the separation between the Lower Esophageal Sphincter (LES) and crural diaphragm (CD). While the link between HH and Gastroesophageal Reflux Disease (GERD) is established, the potential association of HH with esophageal dysmotility, independently from GERD, is uncertain. This study aimed to analyze if HH, with or without GERD, can associate with esophageal motility disorders.

Article Synopsis
- This study investigates how pre-operative esophageal function affects the risk of post-operative issues in obese patients seeking bariatric surgery, particularly focusing on esophageal motility.
- It analyzed data from 104 asymptomatic patients with a BMI of 35 or higher, finding that 90.4% had normal esophageal motility while the rest showed various dysfunctions.
- Results indicated that normative values for esophageal measurements in obese patients differ from those in non-obese individuals, suggesting the need for adjusted standards to avoid misdiagnosis of conditions like esophagogastric junction outflow obstruction.
