The role of endoscopic ultrasound in assessment of physiological cardia insufficiency during diagnosis of hiatal hernia

Abstract

Background. The aim of the study: to determine the role of endoscopic ultrasound (EUS) in assessing the failure of the physiological cardia in the diagnosis of hiatal hernias (HH). Materials and methods. At the Department of Digestive Surgery of the State Institution “Institute of Gastroenterology of the National Academy of Medical Sciences of Ukraine” in 2023, we have performed surgical treatment of 33 patients with HH: axial HH were diagnosed in 21 (63.6 %) cases (I type), paraesophageal HH — in 12 (36.4 %) patients (II type) (ICD-10 code is K44). Control group included 20 practically healthy people. Results. All patients underwent an X-ray and endoscopic examination of the esophagus, stomach, duodenum, and EUS. All 33 (100.0 %) patients underwent an X-ray to confirm the diagnosis and an endoscopic examination to detect changes in the esophageal mucosa. EUS was performed in 31 (93.9 %) patients. The thickness of the esophageal wall was assessed using EUS, which made it possible to determine the state of the structures of the phy­siological cardia in HH: the displacement of part of the stomach above the diaphragm, location of the gastroesophageal junction relative to the legs of the diaphragm and relative to each other; the distance between the legs of the diaphragm (area of the HH) and their length; the cross-sectional area of the HH (hernial sac). The data obtained during EUS influenced the choice of the method for surgical correction of the physiological cardia with HH. Conclusions. Thus, with HH, EUS makes it possible to evaluate pathological changes of the main structures in the failure of the physiological cardia, to improve diagnosis for the types of HH, the location of the gastroesophageal junction, with determination of dimensions of the esophageal hiatus, the distance between the legs of the physiological cardia, localization and cross-section of the hernial sac, which influenced the choice of the surgery for physiological cardia in HH.
