2024年10月24日 · Achalasia (primary achalasia) is a failure of organized esophageal peristalsis that causes impaired relaxation of the lower esophageal sphincter, resulting in food stasis and often marked dilatation of the esophagus.

2022年5月16日 · Achalasia is an esophageal motor disorder characterized by increased lower esophageal sphincter (LES) pressure, diminished-to-absent peristalsis in the distal portion of the esophagus composed of...

2024年11月19日 · Patients with achalasia may present with long-standing and slowly progressive dysphagia to solids and liquids, heartburn, regurgitation, refractory reflux symptoms and noncardiac chest pain. The esophagram and the timed barium swallow are useful imaging studies that may contribute to the diagnosis of achalasia and may be used to determine ...

Achalasia is an esophageal motility disorder characterized by aberrant peristalsis and insufficient relaxation of the lower esophageal sphincter. Patients most commonly present with dysphagia to solids and liquids, regurgitation, and occasional ...

2021年3月21日 · Achalasia subtypes on high-resolution manometry (HRM) prognosticate treatment response and help direct management plan. We aimed to utilize parameters of distension-induced contractility and pressurization on functional luminal imaging probe (FLIP) panometry and machine learning to predict HRM achalasia subtypes.

High-resolution manometry, Chicago Classification v4.0, the functional lumen imaging probe, Panometry, and per-oral endoscopic myotomy (POEM) are all now integral parts of the landscape for managing achalasia or, more precisely, achalasia-like ...

Achalasia Definition F orm of esophageal dysmotility characterized by loss of distal esophageal peristalsis and failure of lower esophageal sphincter relaxation

Manometry is considered as the gold standard for the diagnosis of achalasia, and on its basis, three distinct subtypes are described 1. However, barium swallow studies may show features highly suggestive of this diagnosis in approximately 60% of cases 1 , with the classic sign being tapering of the distal esophagus (rat’s tail or bird’s ...

2025年2月14日 · Short segment of distal esophageal stricture with smooth tapering giving bird beak sign, leading to moderate proximal dilatation, features are suggestive of achalasia. Additionally, multiple distal tertiary contractions are observed, accompanied by delayed passage of …

2 天之前 · Not all will be responsive to treatment for achalasia. Surgeons need to differentiate findings on imaging. Megaesophagus seen on workup: need to rule out distal malignancy. Secondary achalasia can be caused by multiple infectious organisms and …
