Long-Term Results of Radiofrequency Energy Delivery for the Treatment of GERD: Results of a Prospective 48-Month Study

Table 1

Baseline characteristics of treated patients (n = 56)^a.

---

Mean age (yr) 42±14

Male sex, 𝑛 (%) 36 (64.2)

Mean heartburn score 3.8±1.9

Mean HRQL score^b  29±9

Mean SF-36 mental 40±7

Mean SF-36 physical^c 41 ± 7

Daily PPI use, 𝑛 (%) 56 (100)

Median 24-h pH^d 15.85 (5.9–18.2)

Median LES pressure (mmHg) 8.44 (7.2–11.7)

<2 cm hiatal hernia, 𝑛 (%) 28 (50)

Erosive esophagitis at EGD, 𝑛 (%)^e 14 (25)

---

EGD: esophagogastroduodenoscopy; LES: lower esophageal sphincter.
^aMeans report ±1 SD, medians report 25th and 75th percentile ranges, and proportions report absolute numbers (percentiles).
^bHeartburn and heartburn-related quality of life scores (higher scores for worse symptoms).
^cSF-36 physical score (higher scores for better function; U.S. general ‘‘healthy group’’ population mean = 55.3).
^dPercentage of time esophageal pH was <4 (off antisecretory medications).
^eTen patients with grade A and four patients with grade B esophagitis according to the Los Angeles classification.
