Abstract

Abstract:

Objective To systematically evaluate the therapeutic effect of laparoscopic Roux-en-Y gastric bypass (LRYGB) in patients with obesity comorbid with polycystic ovary syndrome (PCOS). Methods A systematic literature search was conducted across four databases (PubMed, Embase, Web of Science, and Scopus) for studies published up to January 1, 2025. Following screening against predefined eligibility criteria, a total of 6 studies comprising 128 patients were ultimately included. Results Following LRYGB, there was a significant reduction in the number of patients with menstrual irregularities (OR=0.07; 95%CI: 0.04~0.14; P<0.05). Additionally, significant improvements were observed in hirsutism (OR=0.14; 95%CI: 0.06~0.32; P<0.05), sex hormone-binding globulin (SHBG) (MD=23.24; 95%CI: 7.97~38.51; P<0.05), free androgen index (FAI) (MD=-3.89; 95%CI: -5.33~-2.45; P<0.05), total testosterone levels (MD=-25.55; 95%CI: -30.08~-21.01; P<0.05), and body mass index (BMI) (MD=-17.22; 95%CI: -19.32~-15.11; P<0.000 1). Conclusions LRYGB can serve as an effective therapeutic intervention to improve body weight and metabolic profiles in the population with obesity comorbid with PCOS.
