Although there are many diseases known to have an effect on esophageal motility, the effect of subepithelial lesions (SELs) of the esophagus on esophageal motility, which is often detected incidentally, remains still unclear. The aim of this study is to reveal the effect of SELs of the esophagus on esophageal motility evaluating it by high-resolution manometry (HRM). PATIENTS AND METHODS: A total of 32 patients with SELs in the esophagus and 12 healthy individuals were included. All patients and controls included in the study underwent HRM using a Unisensor UniTip High Resolution catheter (Laborie, Amsterdam, Netherlands) and endosonographic examination. RESULTS: The mean age was 52.60±15.56 years (range: 23-79) and the average body mass index (BMI) was 26.63±4.71 kg/m2. Gender, height, weight, and BMI measurements, smoking status, alcohol use, and DM status did not statistically differ significantly between the groups (p>0.05). Of 32 patients with SELs, 65.6% (n=21) had lesions originating in the muscularis propria, while 34.4% had lesions originating in the submucosa. The rate of abnormal motility both in the supine and in upright positions of patients with SELs was found to be significantly higher than in the control group (p=0.001, p2 cm), the probability of abnormal HRM results increased. CONCLUSIONS: SELs of the esophagus have pathological effects on esophageal motility, mainly ineffective esophageal motility disorder.
