Background/Aims: The catheter probe endoscopic ultrasonography (EUS) system is widely used to evaluate upper gastrointestinal tract lesions. The depiction of the esophageal wall by probe EUS remains problematic due to the difficulty of the filling of water in the esophageal lumen. In addition, filling the esophagus with water can be associated with an increased risk of aspiration. To resolve such problems, we recently applied the use of probe EUS with the jelly-filled method for the evaluation of subepithelial lesions. The procedure is characterized by filling the esophageal lumen with jelly. In this study, we evaluated the efficacy of probe EUS by using the jelly- filled method for esophageal subepithelial lesions.
Methods: We analyzed the records of the patients with suspected subepithelial lesions at the time of endoscopy that was performed from November 2005 to June 2007. Esophageal subepithelial lesions with both EUS findings and pathological reports were retrospectively compared.
Results: The study included 181 patients (96 males, 85 females), with an average age of 55.5 years (age range, 29∼78 years). Sixty-eight patients had lesions in the upper esophagus, 60 patients had lesions in the middle esophagus and 53 patients had lesions in the lower esophagus. Secondary layers of esophageal lesions were predominant (91/181) in the cases. Pathological findings were available for 34 patients. ompared with the pathological findings, the diagnostic accuracy of EUS was 91.1%.
Conclusions: Probe EUS by using the jelly-filled method is convenient and safe to perform and provides clear and full-circumferential imaging of a lesion. It is an alternative method to use in place of previously used probe-EUS procedures for the assessment of esophageal subepithelial lesions. (Korean J Gastrointest Endosc 2008;36:125-131)
