OBJECTIVES: To compare the outcomes between laparoscopic Nissen fundoplication (LNF) and proton pump inhibitors (PPIs) therapy in patients with laryngopharyngeal reflux (LPR) and type Ⅰ hiatal hernia diagnosed by oropharyngeal pH-monitoring and symptom-scale assessment.
RESULTS: There were 31 patients in the LNF group and 39 patients in the PPI group. Fifty-three patients (25 in the LNF group and 28 in the PPI group) completed reviews and follow-up. Oropharyngeal pH-monitoring parameters were all abnormal with high acid exposure, a large amount of reflux, and a high Ryan score, associated reflux symptom index (RSI) score. There was a significant improvement in the RSI and LPR symptom scores after the 2-year follow-up in both groups (P < 0.05), as well as typical symptoms of gastroesophageal reflux disease. Improvement in the RSI (P < 0.005) and symptom scores of cough (P = 0.032), mucus (P = 0.011), and throat clearing (P = 0.022) was significantly superior in the LNF group to that in the PPI group. After LNF and PPIs therapy, 13 and 53 patients achieved independence from PPIs therapy (LNF: 44.0% vs PPI: 7.14%, P < 0.001) during follow-up, respectively. Patients in the LNF group were more satisfied with their quality of life than those in the PPI group (LNF: 62.49 ± 28.68 vs PPI: 44.36 ± 32.77, P = 0.004). Body mass index was significantly lower in the LNF group than in the PPI group (LNF: 22.2 ± 3.1 kg/m2 vs PPI: 25.1 ± 2.9 kg/m2, P = 0.001).
CONCLUSION: Diagnosis of LPR should be assessed with oropharyngeal pH-monitoring, manometry, and the symptom-scale. LNF achieves better improvement than PPIs for LPR with type I hiatal hernia.
