Popa, Iasi, RomaniaIntroduction: Dyspeptic symptoms in patients with gallstones and persistence ofdyspeptic symptoms after cholecystectomy is common. There is evidence that somesymptoms may be attributed to duodenogastric reflux.Methods: The aim of the study was to quantify duodenogastric reflux in patients withgallstones and in patients with cholecystectomy.The method of 24-h esophageal and gastric Bilitec monitoring was performed in 25patients: 5 healthy, 15 with gallstones and 15 patients with cholecystectomy. Bilirubinreflux was judged when absorbance was 0.15 or more. The duration of reflux comparedto the total observed period was obtained to determine percentage of time. 24-hourmonitoring was completed in all of 35 subjects.Results: Biliary colic was present in 6 patients with gallstones and in 2 patients withcholecystectomy; dyspepsia was present in 8 patients with gallstones and in 6 patientsafter surgery. Only 6 cases had symptoms that was correlated with the presence ofbiliary reflux.The time percentage of esophagus bilirubin reflux was less than 5% in all controls. In7 patients with gallstones and also in 9 patients with cholecystectomy the timepercentage of bilirubin reflux was more than 8%; in 2 cases with gallstones and also in4 cases after surgery the duodenogastric reflux was greater than 20%.Discussion/Conclusion: 24-hour bile monitoring provides the clinician evidence ofexcessive biliary reflux in patients with gallstones and in patients with cholecystectomy.According to this study, there are poor correlations between the presence of the biliaryreflux and dyspeptic symptoms.
