Nissen Fundoplication for Laryngopharyngeal Reflux After Patient Selection Using Dual pH, Full Column Impedance Testing: A Pilot Study

Objectives:

Prior studies demonstrate inconsistent diagnostic strategies for laryngopharyngeal reflux disease (LPR) patients who are offered laparoscopic Nissen fundoplication (Nissen). Superior symptom resolution outcomes are demonstrated in patients with accompanying typical gastroesophageal reflux (GERD) symptoms. This study aims to evaluate the efficacy of selecting patients with LPR complaints for Nissen using full column, dual pH impedance catheters (multichannel intraluminal impedance catheters [MII]).

Methods:

All patients who underwent Nissen for management of LPR symptoms refractory to at least 3 months of twice daily (BID) proton pump inhibitor (PPI) therapy with reflux symptom index (RSI) of 13 or higher and who had demonstrable reflux on MII were included. Pre- and (minimum) 16 week post-Nissen RSI scores as well as LPR-specific complaints were collected.

Results:

Eleven patients met criteria. Nine subjects (5 female, 4 male) had complete data. All 9 (100%) achieved improvement in RSI. The average pre-Nissen RSI was 31.7, and average post-Nissen RSI was 10 (P < .001). Six (67%) subjects dropped below an RSI of 13. Seven subjects (78%) had resolution of their primary LPR symptom, and 6 (67%) subjects had resolution of all LPR symptoms.

Conclusions:

Patients with LPR who are selected using dual pH and full column impedance are likely to demonstrate improvement in RSI following Nissen.
