Abstract   Dysphagia is a symptom suggestive of severe underlying pathology, although its causes include organic and non-organic disorders. A balance must be struck between the potential complications of any invasive investigation and its diagnostic utility, especially for elderly patients with dysphagia. The aim of this study was to investigate whether transabdominal ultrasonography (TUS) can differentiate among patients complaining of esophageal dysphagia including achalasia, distal esophageal spasms (DES), neoplasms involving the esophagogastric junction (EGJ) and healthy controls. Methods All patients complained of esophageal dysphagia, while healthy controls had no symptoms originating from esophagus. TUS was performed in 50 patients with achalasia, 17 DES patients, 10 patients with neoplasms, and 39 sex- and age-matched controls. All studies were performed with a 3.5 MHz real time curved array scanner and using an electronic caliper to measure esophageal wall thickness and the maximum esophageal diameter at 3 cm from EGJ. Manometric diagnoses were made based on the Chicago classification ver.3. The cutoff value of each TUS parameter was then calculated. Specificity and sensitivity in making a diagnosis of each disease were determined. Results There were significantly differences in the TUS parameters among four groups (Fig). The cutoff value of diameter of esophageal lumen to differentiate achalasia from other 3 groups was calculated as 13.1 mm (sensitivity, 0.96; specificity, 0.93), with an area under the curve (AUC) of 0.99, and that of esophageal wall thickness to differentiate both the tumor and DES groups from the other two groups was 3.5 mm (sensitivity, 0.64; specificity, 0.62), respectively. Using these parameters, sensitivity and specificity of diagnosis was 0.56 and 0.95 in achalasia, 1.00 and 0.24 in DES, and 1.00 and 0.21 in tumors. Conclusion TUS is a useful, non-invasive diagnostic aid in differentiating patients with primary achalasia from those with other causes of dysphagia.

Objective: To evaluate multidetector computed tomography (MDCT) findings in patients with achalasia, to assess its role in differentiating subtypes in detecting lung involvement and extra-esophageal thoracic complications. Subjects and Methods: This clinical retrospective study included 51 patients with manometrically confirmed achalasia who underwent chest X-ray and MDCT in diagnostic work-up. Esophageal wall thickness and morphology, luminal dilatation, lung changes, and extra-esophageal manifestations were analyzed on MDCT by 2 readers. Wilcoxon, Kruskal-Wallis and Mann-Whitney test were used for assessing the differences among the achalasia subtypes, and intra-class correlation coefficients (ICC) assessing the inter-observer agreement between the measurements of 2 readers. Results: Fourteen (27.5%) patients had achalasia subtype I, 21 (60.8%) had subtype II while 6 (11.8%) had subtype III. Esophageal wall thickness of the esophageal body (EB) and distal esophageal segment (DES) as well as nodular/lobulated appearance of DES were found significantly more often in subtype III (p = 0.024, p < 0.001, p = 0.009, respectively). Esophageal dilatation gradually decreased from subtype I to III (p = 0.006). Chest X-ray revealed lung changes in 9 (17%) and MDCT in 21 (41%) patients (p = 0.001), most frequently in subtype I, with predominance of ground-glass opacities. Tracheal/carinal compression was detected in 27 (52.9%) and left atrial compression in 17 (33.3%) patients. Excellent inter-observer agreement was observed in measuring the EB and DES wall thickness, and diameter of EB (ICC 0.829, 0.901, and 0.922). Conclusion: MDCT is a useful tool for detecting lung and extra-esophageal thoracic complications in patients with achalasia, and could be a valuable additional imaging modality in the differentiation of achalasia subtypes.
