Backgrounds And AimsThis study aimed to compare the esophageal motility between gastroesophageal reflux disease (GERD) patients with typical symptoms but without globus sensation and GERD patients only with globus symptoms.MethodsA total of 57 consecutive GERD patients diagnosed by endoscopy or by 24-hour pH monitoring between May 2013 and September 2015 were included retrospectively into the study. The patients were grouped based on the presence or absence of globus. Thirty patients presented with typical reflux symptoms but without globus were assigned to the typical GERD group and 27 patients only with globus symptom were assigned to the globus GERD group. All patients underwent esophageal high resolution manometry (HRM) and the differences in esophageal motility between the two groups were analyzed.ResultsThe globus GERD group showed a significantly greater lower esophageal sphincter (LES) length, LES basal pressure and upper esophageal sphincter (UES) residual pressure than that of the typical GERD group (3.47 ± 0.76 vs. 2.65 ± 0.62 cm, 21.71 ± 9.68 vs. 16.04 ± 8.49 mmHg, 7.30 ± 4.42 vs. 4.12 ± 2.92 mmHg, all p < 0.05). There was no significant difference between the two groups in terms of the distal wave amplitude, mean wave duration, distal contractile integral (DCI), contractile front velocity (CFV), distal latency (DL), integrated relaxation pressure (IRP) and UES basal pressure. The incidence of esophageal dysmotility in the globus GERD group (33.3%) was higher than in the typical GERD group (23.3%). There was no significant difference in esophageal acid exposure of the non-erosive gastroesophageal reflux disease (NERD) patients between the two groups.ConclusionsGlobus GERD patients have a higher UES residual pressure, longer LES length, higher LES basal pressure and greater esophageal dysmotility than typical GERD patients. HRM is useful in evaluating esophageal motility of GERD patients.
