| Abstract |
Clinical characteristics of laryngopharyngeal reflux (LPR) in Japanese population remain unclear, and its treatment outcome is suboptimal. The objectives of this study were to evaluate Japanese patients with LPR symptoms using hypopharyngeal multichannel intraluminal impedance (HMII) and to assess the outcome of antireflux surgery (ARS). Subjects included patients who had LPR symptoms for > 12 weeks or laryngoscopic findings suggestive of LPR and underwent laryngoscopy and esophageal testing including HMII. Abnormal proximal exposure (APE) was defined as LPR ≥ 1/day and/or full column reflux (FCR) (reflux 2 cm distal to the upper esophageal sphincter) ≥ 5/day on HMII. Patients with APE were offered ARS and the outcome of ARS was objectively assessed using Reflux Symptom Index (RSI). From July 2015 to September 2016, 52 patients with LPR symptoms (28 men, 24 women, median BMI 22.3) underwent HMII, and 38 patients (73%) had APE. Of them, 29 (76%) patients were not obese (BMI < 25) and 19 (50%) patients had a negative DeMeester score. Approximately one-third of LPR and FCR events were non-acid in the distal esophagus. A positive symptom-association probability was seen only in 18 patients (35%). Mild esophagitis and hiatal hernia were found in 5 (10%) and 23 (48%) patients, respectively. All 12 patients (100%) who had undergone ARS were able to discontinue PPI and had a significant improvement in the RSI scores postoperatively (22.9 ± 10.0 vs. 6.8 ± 6.8, p < .001). APE was frequently observed in Japanese patients with LPR symptoms. Obesity and esophagitis were uncommon in this population. Since a large number of patients with APE had negative DeMeester score and proximal reflux events were often non-acid, a conventional pH monitoring is insufficient. HMII is crucial to evaluate patients with LPR symptoms as the documentation of APE is a key for successful outcome of ARS. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 03 July 2018.
All research outputs
#14,960,072
of 23,011,300 outputs
Outputs from Surgical Endoscopy
#3,608
of 6,102 outputs
Outputs of similar age
#252,855
of 440,043 outputs
Outputs of similar age from Surgical Endoscopy
#131
of 164 outputs
Altmetric has tracked 23,011,300 research outputs across all sources so far. This one is in the 32nd percentile – i.e., 32% of other outputs scored the same or lower than it.
So far Altmetric has tracked 6,102 research outputs from this source. They receive a mean Attention Score of 4.1. This one is in the 37th percentile – i.e., 37% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 440,043 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 39th percentile – i.e., 39% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 164 others from the same source and published within six weeks on either side of this one. This one is in the 17th percentile – i.e., 17% of its contemporaries scored the same or lower than it.
