Abstract: Background The aim of this study was to evaluate the value of salivary pepsin to assess the outcome of surgical treatment of patients with gastroesophageal reflux (GERD). Methods Forty-five consecutive patients with GERD despite proton pump inhibitor treatment received laparoscopic anti-reflux surgery (LARS). 24-hour esophageal pH-monitoring (MII-pH) and esophageal manometry (HRM) data were documented preoperatively and at 3-month follow-up. Clinical symptoms were rated with the Gastrointestinal Quality of Life Index (GIQLI) and gastrointestinal symptoms were evaluated by a standardized symptom checklist (SCL), assessing the severity and intensitiy of 14 different symptoms. Simultaneous to MII-pH the collection of 3 saliva samples per patient was performed. Treatment failure was defined as improvement of GIQLI and SCL of < 10 points, despite showing a normal DeMeester score. Results At baseline, all patients showed a pathological MII-pH measurement. Furthermore, all patients showed postoperatively a normal DeMeester score (mean 7.10 ± 4.56). Ten patients were defined as treatment failures with a change of pepsin concentration from a mean value of 198.73 ng/mL to 186.00 ng/mL (p>0.05). In patients defined as treatment success, mean pepsin value decreased from 205.83 ng/mL to 85.24 ng/mL (p<0.001). Conclusion Salivary pepsin could be a marker for treatment success after LARS. However, larger studies are required to reach firm conclusions.
