Introduction: According to the Rome IV criteria the diagnosis of rumination in children is based on typical symptoms during clinical evaluation. High resolution manometry/impedance (HRM/Z) can be used to confirm the clinical suspicion of rumination but is rather poorly tolerated in children and only records one postprandial period.

Aims & Methods: The aim of our study was to identify a specific diagnostic pattern of rumination during ambulatory Impedance-pH-metry (MII-pH).

We retrospectively assessed MII-pH tracings from children with clinical diagnosis of rumination syndrome confirmed by HRM/Z (minimal 2 typical rumination episodes in postprandial evaluation). We then compared the MII-pH parameters of these patients with those from children with GERD and “non-GERD” children (investigated for possible GERD but with normal MII-pH). We established cut-off levels for significant MII-pH parameters and developed a rumination-specific scoring system. We then validated the scoring system on another group of patients who underwent both HRM/Z and MII-pH (traces scored blindly).

Results: We identified 12 children with confirmed diagnosis of rumination based on HRM/Z findings (median age: 13.9 years, 6M:6F). Another 18 children were identified with GERD (median age: 8.1 years, 8M:10F) and 12 children with non-GERD (median age: 12.4 years, 6M:6F). Children with rumination had significantly higher number of total reflux events (RE)/24 hrs, total number of proximal RE/24 hrs (p< 0.0001) and postprandial non-acid RE/hr (p=0.0072) compared to GERD and non-GERD groups. The SAP for regurgitation/reflux/vomiting was significantly higher in the rumination group (p=0.0009). The scoring system includes: 1)Total proximal RE/24hrs >57.5, 2)Postprandial non-acid RE/hr >2, 3)SAP for regurgitation/reflux/vomiting >97.5. Each parameter scores 1 and rumination is diagnosed if the score is < 2. We validated the scoring system in a group of 18 children who underwent both a HRM/Z and MII-pH (8 diagnosed with rumination - 3M:5F, median age: 13 years - and 10 with a negative HRM/Z - 4M:6F, median age:8.5 years). The sensitivity and specificity of the score is 75% and 80% respectively.

Conclusion: Children with rumination have many more symptomatic reflux episodes (SI/SAP positive) with high proximal extent, particularly during postprandial periods compared to GERD and controls. Our scoring system allows for early identification of children with rumination syndrome.
