A complete of 34 individuals got erosive esophageal mucosa, 76 individuals had regular esophageal mucosa on endoscopy. After MII-pH monitoring, 34 (31%) individuals were assigned towards the acid reflux disorder group, 44 (40%) individuals were assigned towards the NAR group, and 32 (29%) topics were contained in the nonreflux group. Among the 78 individuals with reflux, a complete of 5962 reflux occasions were documented, including 2025 (34%) shows of acid reflux disorder and 3937 (66%) shows of NAR. The median amount of total reflux shows per affected person was 45 (IQR, 22C72), 15 (4C28) in the acid reflux disorder group, and 25 (13C45) in the NAR group. Eighty-two (75%) individuals recorded symptoms through the monitoring period, and 28 (25%) individuals got no symptoms during this time period. The 82 symptomatic individuals recorded a complete of 135 GERD symptoms, including 62 normal and 73 atypical symptoms. These symptoms (Desk ?(Desk1)1) contains the next: acid reflux, 25 (23%) individuals; regurgitation, 22 (20%) individuals; belching, 22 (20%) individuals; coughing, 21 (19.1%) individuals; chest discomfort, 15 (13.6%) individuals; nausea, 11 (10%) individuals; abdominal distress, 10 (9.1%) individuals; hiccups, 7 (6.4%) individuals; and throat distress, 2 (1.8%) individuals.

Relationship between NMBI and reflux shows The median distal esophageal MNBI was considerably reduced the acid reflux disorder group (1244?; IQR, 647C1969?) than in the NAR group (2586?; IQR, 1368C3666?) and nonreflux group (3082?; IQR, 2495C4472?, all em P /em ? ?.001; Fig. ?Fig.1).1). Even though the distal esophageal MNBI was reduced the NAR group than in the nonreflux group, no factor was found between your 2 organizations ( em P /em ?=?.78).

Correlation between symptom-reflux association and reflux episodes We further separated the 33 individuals with positive SAP into those with typical symptoms and those with atypical symptoms (Fig. ?(Fig.3).3). Among these individuals, 12 (37%) experienced typical symptoms only, 15 (45%) experienced atypical symptoms only, and 6 (18%) experienced both standard and atypical symptoms.

After MII-pH monitoring, 34 (31%) individuals were assigned to the acid reflux group, 44 (40%) individuals were assigned to the NAR group, and 32 (29%) subjects were included in the nonreflux group. Among the 78 individuals with reflux, a total of 5962 reflux events were recorded, including 2025 (34%) episodes of acid reflux and 3937 (66%) episodes of NAR.
