McNemar test was used for paired categorical data. Correlations of continuous data were investigated with the Spearman’s correlation coefficient.
Multiple linear regression analysis was performed to identify parameters predictive of change in acid exposure after operation. Variables included in the analysis were based on univariable analysis and included: age, neurologic impairment and weight-for-height percentile.
Statistical significance was, when possible, expressed by 95% confidence intervals. Where p-values were used, statistical significance was defined by p-values of less than 0.05. All analyses were performed using SPSS 24.0 statistical package (IBM, USA).
ResULTs
In total 50 patients were included and successfully underwent preoperative 24-hour MII-pH metry. Caregivers of all patients filled out the reflux questionnaires. Out of these 50 patients, postoperative 24-hour MII-pH monitoring was successfully performed in 25 patients (50%). In 20 out of the 25 patients without a postoperative test the reason was refusal by the caregivers or inability of the children to undergo the postoperative tests. A total of 25 patients were included in the analysis of MII-pH test results. The flowchart of patient inclusion is depicted in Figure 1.

Patient characteristics of both participants and non-participants in the MII-pH study are described in Table 1. Median follow-up time after GP was 3.9 months (IQR 3.6 – 4.9). Mortality rate during follow-up was 0%. In one out of 25 patients the gastrostomy was removed because of recurrent leakage at the gastrostomy site leading to persistent local infection.
