BACKGROUND: With the development of high-resolution manometry (HRM) and peroral endoscopy, more patients with esophageal motility disorders (EMDs) including achalasia are diagnosed and treated. The characteristics of Japanese patients with EMDs are unknown and should be elucidated.
METHODS: A large-scale database analysis was performed at seven high-volume centers in Japan. EMDs between 2010 and 2019 were analyzed.
RESULTS: A total of 1900 patients were diagnosed with treatment naïve achalasia on esophagography. A long disease history was related to the sigmoid and dilated esophagus, and patients' symptom severity declined as achalasia progressed to the sigmoid type. Among 1700 patients received starlet HRM, 1476 (86.8%) completed the examination. Long disease history and sigmoid achalasia were identified as risk factors for the failure of HRM examination. Type I achalasia was the most common type found on starlet HRM, and 45.1% of patients with achalasia had lower esophageal sphincter (LES) pressure within the normal range. Type III had a high age of onset and mild symptom severity, compared to the other two subtypes. Type III achalasia, esophagogastric outflow obstruction (EGJ-OO), jackhammer esophagus (JE), and diffuse esophageal spasm (DES) were relatively rare compared to type I-II achalasia. The clinical characteristics of EGJ-OO, JE, and DES were generally close to those of achalasia.
CONCLUSION: This first large-scale database analysis indicates that more Japanese patients with achalasia are type I and have a normal range of LES pressure on starlet HRM. Failure of HRM is not rare; therefore, esophagography continuously has a complementary role in achalasia diagnosis.
