Abstract

Introduction: Absent contractility is a kind of esophageal motility disorder. Patients are often diagnosed by endoscopic ultrasonography or high-resolution manometry (HRM). In this paper, we report two cases of absent esophageal contractility first discovered by transabdominal ultrasonography.

Case Presentation: The main symptom of both cases was acid reflux, and the main diagnosis was absent esophageal contractility. They were all discovered by transabdominal ultrasonography. After the treatment of surgery or drugs, the symptoms relieved during follow-up, without any other discomforts.

Conclusion: Transabdominal ultrasound as a primary screening method for absent contractility is proposed in this paper, which is non-invasive, real-time, and fast. Ultrasound is expected to improve the diagnostic efficiency of peristalsis and patient experience in combination with the above invasive examinations. The use of sonography in the diagnosis of absent contractility has seldom been studied. Further investigation is required to determine whether this technique may better assess absent contractility.
