The effect of endoscopic gastric plication on portosystemic pressure gradient in patients with nonalcoholic fatty liver disease and compensated advanced chronic liver disease

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 ultrasoundguided PPGmeasurement prior to and at 6months 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 5.4mmHg (range 0.7.19.6) to 1.8mmHg (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. © 2022 Georg Thieme Verlag.
