Introduction:  In the structure of acute chemical poisonings, chemical burns of the esophagus (CBE) rank second, occurring with a frequency of up to 15.9% [1]. The most common corrosive chemicals are acetic acid and alkalis found in household cleaners [2]. Esophagogastroduodenoscopy (EGD) is considered the “gold standard” for diagnosing chemical burns in the upper gastrointestinal tract, including the esophagus; however, it does not allow for the determination of the depth of esophageal wall damage or the prediction of potential risk for developing scar stenosis [3]. Unlike EGD, endoscopic ultrasound (EUS) enables the assessment of the structure of each layer of the esophageal wall and its involvement in the pathological process [4].

Keywords:

Digital Formats:  During EUS, damaged esophageal wall layers were highly echogenic with a heterogeneous echo structure. Increased thickness and impaired differentiation of the contours and boundaries of the damaged esophageal wall layers were noted. Based on changes in their structure during EUS, we developed the following grading for damage to the muscular layers of the esophageal wall: grade 4a, 4b, 4c, 4d (Fig. 1 and Fig. 2).

Fig 1:

Fig 2. A – Grade 4a esophageal reflux disease. 1 – Impaired differentiation of the mucosa and submucosal layers, 2 and 3 – thickened circular and longitudinal muscle layers, 4 – ultrasound mini-transducer.

B – Grade 4b esophageal reflux disease. 1 – Partially damaged circular muscle layer, 2 – intact longitudinal muscle layer, 3 – damage extending to the submucosal and circular muscle layers, 4 – ultrasound mini-transducer.

B – Grade 4c esophageal reflux disease. 1 – Partially damaged longitudinal muscle layer, 2 – damage extending to the submucosal, circular muscle, and partially longitudinal muscle layers, 3 – ultrasound mini-transducer.

D – Grade 4d esophageal reflux disease. 1 – damage extending to all layers of the esophageal wall, 2 – ultrasound mini-transducer.
