Assessment of Esophageal Dysmotility Disorder by High Resolution Manometry in Systemic Sclerosis: Association with Clinical Features
Aim of the Study: To find association between clinical features of systemic sclerosis and esophageal dysmotility disorder based on high resolution manometry (HRM) findings according to the 3rd version of Chicago classification.
Methods: In a cross-sectional study in Firozgar hospital we recruited 150 consecutive SSc patients. All patients fulfilled the 2013 ACR/EULAR classification for SSc criteria. We used water-perfused esophageal high resolution manometry (HRM) having 26-channel silicone-customized catheter.
Results: From all 150 SSc patients who were included in the study, forty-nine (46%) had dcSSc subset of disease with mean age (SD) 47.0 (12.1) years. According to the 3rd version of the Chicago classification, 135 (90%) patients had ineffective peristalsis [weak peristalsis in 24 (16.0%) and failed peristalsis in 111 (74.0%) of patients]. Hypotensive Esophagogastric junction pressure (hEGJP) presented in 47 (31.3%) patients. Two (1.3%) patients had achalasia in HRM. Age, gender, and duration of disease were not different in the above two groups of patients. In multivariate model FVC%, [OR (CI95%): 1.055(1.025-1.086), p<0.001] showed significant association with failed peristalsis.Comparison between average rank of FVC% in peristalsis status groups showed significant difference between average rank of FVC% in patients with failed peristalsis and weak peristalsis p=0.001, and average rank of FVC% in those with failed peristalsis and normal peristalsis p=0.020.
Conclusions: Our findings showed that esophageal dysmotility is a frequent finding in systemic sclerosis patients. The results demonstrated that FVC%, tendon friction rub kept significant concordance with failed peristalsis. Moreover, we noticed a concordance between HRM results and severity of FVC.
