	1	Acid and non-acid reflux in patients refractory to proton pump inhibitor therapy:Is gastroparesis a factor?显示文摘AIM:To determine whether an increased number and duration of non-acid reflux events as measured using the multichannel intraluminal impedance pH(MII-pH)is linked to gastroparesis(GP).METHODS:A case control study was conducted in which 42 patients undergoing clinical evaluation for continued symptoms of gastroesophageal reflux disease(both typical and atypical symptoms)despite acid suppression therapy.MII-pH technology was used over 24 h to detect reflux episodes and record patients’symptoms.Parameters evaluated in patients with documented GP and controls without GP by scintigraphy included total,upright,and supine number of acid and non-acid reflux episodes(pH<4 and pH>4,respectively),the duration of acid and non-acid reflux in a 24-h period,and the number of reflux episodes lasting longer than 5 min.RESULTS:No statistical difference was seen between the patients with GP and controls with respect to the total number or duration of acid reflux events,total number and duration of non-acid reflux events or the duration of longest reflux episodes.The number of nonacid reflux episodes with a pH>7 was higher in subjects with GP than in controls.In addition,acid reflux episodes were more prolonged(lasting longer than 5min)in the GP patients than in controls;however,these values did not reach statistical significance.Thirty-five patients had recorded symptoms during the 24 h study and of the 35 subjects,only 9%(n=3)had a positive symptom association probability(SAP)for acid/non-acid reflux and 91%had a negative SAP.CONCLUSION:The evaluation of patients with a documented history of GP did not show an association between GP and more frequent episodes of non-acid reflux based on MII-pH testing.
