Abstract
Background The goals of therapy for patients with nonalcoholic fatty liver disease and compensated
advanced chronic liver disease include weight loss and reduction of the portosystemic
pressure gradient (PPG) to decrease the risk of hepatic decompensation. Endoscopic
gastric plication (EGP) is an effective endoscopic weight loss procedure. This study
aimed to assess the effect of EGP on PPG.
Methods In this prospective pilot study, patients with nonalcoholic fatty liver disease and
compensated advanced chronic liver disease underwent endoscopic ultrasound-guided
PPG measurement prior to and at 6 months following EGP. Primary outcomes were the
change in PPG and proportion of patients experiencing ≥ 20 % reduction in PPG at 6
months. Secondary outcomes included percent total weight loss (TWL) and changes in
noninvasive tests of fibrosis.
Results 20 patients were included. Baseline median body mass index and liver stiffness measurement
were 40.2 kg/m2 (range 30.1–56.7) and 14.7 kPa (range 8.2–36), respectively. At 6 months, median
PPG decreased from 5.4 mmHg (range 0.7–19.6) to 1.8 mmHg (range 0.4–17.6) (P = 0.002), with 79 % (11/14) experiencing ≥ 20 % reduction. Patients experienced 12.5 %
(6.5 %–26.1 %) TWL (P < 0.001) at 6 months, with 89 % (17/19) achieving ≥ 7 % and 68 % (13/19) achieving
≥ 10 % TWL. There were significant improvements in noninvasive tests of fibrosis.
Conclusion EGP appeared to be effective at reducing PPG in patients with nonalcoholic fatty
liver disease and compensated advanced chronic liver disease.
