6-Month Gastrointestinal Quality of Life (QoL) Results after Endoscopic Sleeve Gastroplasty and Laparoscopic Sleeve Gastrectomy: A Propensity Score Analysis.

Abstract

Laparoscopic sleeve gastrectomy (LSG) is currently the most commonly performed bariatric procedure. Endoscopic sleeve gastroplasty (ESG) is a promising new bariatric technique which is less invasive in its approach. To date no study has compared quality of life (QoL) outcomes between LSG and ESG. The aim of this study is to compare QoL after ESG and LSG using a propensity score analysis. QoL was evaluated by means of Gastrointestinal Quality of Life Index (GIQLI) questionnaire before and 6months after the procedure. Patients were matched for age, sex, preoperative weight, and comorbidities. Propensity score matching resulted in 23 pairs of patients homogeneous for age (p = 0.3), preoperative BMI (p= 0.3), sex (p= 0.74), and comorbidities (p= 0.9). Post-ESG patients, despite a less important %EWL (39.9 (17.5-58.9)vs 54.9 (46.2-65); p= 0.01) and %TWL (13.4 (7.8-20.9) vs 18.8 (17.6-21.8); p= 0.03), presented better QoL (14 [3-24] vs 13 (- 1-23) ΔGIQLI score; p= 0.79) with clear advantage for the gastrointestinal symptoms subdomain (66.5 (61-70.5) vs 59 (55-63); p= 0.001), while post-LSG patients presented a worsening of GERD symptoms (30.7% vs 0%) and an increased use of PPI therapy (p= 0.004). Resolution or improvement of comorbidities was similar (ESG 53% vs LSG 45.8%; p= 0.79) in both groups. LSG may significantly affect QoL and results in worsening of gastrointestinal symptoms including GERD. ESG is a promising less invasive bariatric endoscopic procedure that demonstrated a positive impact on both QoL and comorbidities, which could lead to greater patient acceptance earlier in their disease or at a younger age.
