Durability of Stretta Radiofrequency Treatment for GERD: Results of an 8-Year Follow-Up

Table 1

Baseline characteristics of patients who reached an 8-year follow-up after Stretta procedure (𝑛=26)^a.

Mean age (yr)	36±18
Male sex	𝑛=10 (38.4%)
Mean heartburn score^b	3.8±1.9
Mean HRQL score^b	31±7
Mean SF-36 mental^c	42±9
Mean SF-36 physical^c	40±6
Daily PPI use	𝑛=26 (100%)
Median 24 hs pH^d	16.85 (9.9–18.4)
Median LES pressure (mmHg)	9.30 (7.2–11.0)
<2 cm hiatal hernia	𝑛=6 (23%)
Erosive esophagitis at EGD^e	𝑛=7 (27)

EGD: esophagogastroduodenoscopy; LES: lower oesophageal 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, [13]).
^cSF-36 physical score (higher scores for better function; US general “healthy group” population mean = 55.3 [14]).
^dPercentage of time of oesophageal pH < 4 (off antisecretory medications).
^eSix patients with grade A and one patient with grade B esophagitis according to the Los Angeles classification.
